Bloom's Taxonomy of Learning Domains - 0 views

  • Since the work was produced by higher education, the words tend to be a little bigger than we normally use. Domains may be thought of as categories. Instructional designers, trainers, and educators often refer to these three categories as KSA (Knowledge [cognitive], Skills [psychomotor], and Attitudes [affective]). This taxonomy of learning behaviors may be thought of as “the goals of the learning process.” That is, after a learning episode, the learner should have acquired a new skill, knowledge, and/or attitude. While the committee produced an elaborate compilation for the cognitive and affective domains, they omitted the psychomotor domain. Their explanation for this oversight was that they have little experience in teaching manual skills within the college level. However, there have been at least three psychomotor models created by other researchers.
  •  
    The Three Types of Learning: A committee of colleges, led by Benjamin Bloom (1956), identified three domains of educational activities: Cognitive: mental skills (Knowledge); Affective: growth in feelings or emotional areas (Attitude); Psychomotor: manual or physical skills (Skills). Domains can be thought of as categories. Trainers often refer to these three categories as KSA (Knowledge, Skills, and Attitude). This taxonomy of learning behaviors can be thought of as "the goals of the learning process." That is, after a learning episode, the learner should have acquired new skills, knowledge, and/or attitudes.

Issues about Outcomes Based Education - 0 views

  • Outcome-based education (OBE) is one of those that is new, even revolutionary, and is now being promoted as the panacea for America's educational woes. This reform has been driven by educators in response to demands for greater accountability by taxpayers and as a vehicle for breaking with traditional ideas about how we teach our children. If implemented, this approach to curriculum development could change our schools more than any other reform proposal in the last thirty years.
  • According to William Spady, a major advocate of this type of reform, three goals drive this new approach to creating school curricula. First, all students can learn and succeed, but not on the same day or in the same way. Second, each success by a student breeds more success. Third, schools control the conditions of success. In other words, students are seen as totally malleable creatures. If we create the right environment, any student can be prepared for any academic or vocational career. The key is to custom fit the schools to each student's learning style and abilities.
  • Outcome-based education will change the focus of schools from the content to the student
  • ...29 more annotations...
  • The teacher's role in the classroom will become that of a coach. The instructor's goal is to move each child towards pre-determined outcomes rather than attempting to transmit the content of Western civilization to the next generation in a scholarly fashion
  • the focus is no longer on content. Feelings, attitudes, and skills such as learning to work together in groups will become just as important as learning information--some reformers would argue more important.
  • Where traditional curricula focused on the past, reformers argue that outcome-based methods prepare students for the future and for the constant change which is inevitable in our society.
  • Reformers advocating an outcome-based approach to curriculum development point to the logical simplicity of its technique. First, a list of desired outcomes in the form of student behaviors, skills, attitudes, and abilities is created. Second, learning experiences are designed that will allow teachers to coach the students to a mastery level in each outcome. Third, students are tested. Those who fail to achieve mastery receive remediation or retraining until mastery is achieved. Fourth, upon completion of learner outcomes a student graduates.
  • According to William Spady, a reform advocate, outcomes can be written with traditional, transitional, or transformational goals in mind. Spady advocates transformation goals.
  • Traditional outcome-based programs would use the new methodology to teach traditional content areas like math, history, and science
  • Many teachers find this a positive option for challenging the minimal achiever
  • An outcome-based program would prevent such students from graduating or passing to the next grade without reaching a pre-set mastery level of competency.
  • Transformational OBE subordinates course content to key issues, concepts, and processes. Indeed, Spady calls this the "highest evolution of the OBE concept." Central to the idea of transformational reform is the notion of outcomes of significance.
  • Spady supports transformational outcomes because they are future oriented, based on descriptions of future conditions that he feels should serve as starting points for OBE designs
  • little mention is made about specific things that students should know as a result of being in school.
  • The focus is on attitudes and feelings, personal goals, initiative, and vision--in their words, the whole student.
  • It is in devising learner outcomes that one's world view comes into play. Those who see the world in terms of constant change, politically and morally, find a transformation model useful. They view human nature as evolving, changing rather than fixed.
  • Advocates of outcome-based education point with pride to its focus on the student rather than course content. They feel that the key to educational reform is to be found in having students master stated learner outcomes. Critics fear that this is exactly what will happen. Their fear is based on the desire of reformers to educate the whole child. What will happen, they ask, when stated learner outcomes violate the moral or religious views of parents?
  • Under the traditional system of course credits a student could take a sex-ed course, totally disagree with the instruction and yet pass the course by doing acceptable work on the tests presented. Occasion-ally, an instructor might make life difficult for a student who fails to conform, but if the student learns the material that would qualify him or her for a passing grade and credit towards graduation.
  • If transformational outcome-based reformers have their way, this student would not get credit for the course until his or her attitudes, feelings, and behaviors matched the desired goals of the learner outcomes.
  • Another goal requires students to know about and use community health resources. Notice that just knowing that Planned Parenthood has an office in town isn't enough, one must use it.
  • transformational outcome- based reform would be a much more efficient mechanism for changing our children's values and attitudes about issues facing our society
  • the direction these changes often take is in conflict with our Christian faith
  • "Who has authority over our children?"
  • Outcome-based education is an ideologically neutral tool for curricular construction; whether it is more effective than traditional approaches remains to be seen. Unfortunately, because of its student-centered approach, its ability to influence individuals with a politically correct set of doctrines seems to be great. Parents (and all other taxpayers) need to weigh the possible benefits of outcome-based reform with the potential negatives.
  • who will determine the learner outcomes for their schools
  • consideration of what learner outcomes the public wants rather than assuming that educators know what's best for our children. Who will decide what it means to be an educated person, the taxpaying consumer or the providers of education?
  • If students are going to be allowed to proceed through the material at their own rate, what happens to the brighter children? Eventually students will be at many levels, what then? Will added teachers be necessary? Will computer-assisted instruction allow for individual learning speeds? Either option will cost more money. Some reformers offer a scenario where brighter students help tutor slower ones thereby encouraging group responsibility rather than promoting an elite group of learners. Critics feel that a mastery- learning approach will inevitably hold back brighter students.
  • With outcome-based reform, many educators are calling for a broader set of evaluation techniques. But early attempts at grading students based on portfolios of various kinds of works has proved difficult. The Rand Corporation studied Vermont's attempt and found that "rater reliability--the extent to which raters agreed on the quality of a student's work--was low." There is a general dislike of standardized tests among the reformers because it focuses on what the child knows rather than the whole child, but is there a viable substitute? Will students find that it is more important to be politically correct than to know specific facts?
  • whether or not school bureaucracies will allow for such dramatic change? How will the unions respond? Will legislative mandates that are already on the books be removed, or will this new approach simply be laid over the rest, creating a jungle of regulations and red tape?
  • although districts may be given input as to how these outcomes are achieved, local control of the outcomes themselves may be lost.
  • Many parents feel that there is already too much emphasis on global citizenship, radical environmentalism, humanistic views of self-esteem, and human sexuality at the expense of reading, writing, math, and science.
  • education may become more propagandistic rather than academic in nature

Inclusion of preschool children with autism in Sweden: attitudes and perceived efficacy... - 0 views

  • This pilot study examined the relations among preschool teachers' attitudes towards the inclusion of children with autism and perceived self-efficacy, as well as demographic characteristics such as teachers' work experience and educational background. The cohort consisted of 21 participants who had degrees in preschool education and worked with children with autism in general preschool/kindergarten settings in central Sweden.
  • In general, findings revealed that preschool teachers held positive attitudes towards children with autism,
  • teachers showed neutral attitudes towards the inclusion of children with autism into general preschool classrooms
  • ...2 more annotations...
  • this was significantly related to the number of credits in special education taken during pre-service education
  • No relations were found between teachers' perceived self-efficacy and attitudes towards inclusion, although a relationship was found between participation in in-service training and efficacy to make decisions.

5 Tips on Spoken Word | Power Poetry - 0 views

  • Choose a subject and have attitude. No attitude, no poem! Feelings and opinions give poetry its “richness.” Each poet has a unique perspective and view of the world that no one else has. It is important that a spoken word poem embodies the courage necessary to share one’s self with the rest of the world. The key here is to build confidence. We must acknowledge ourselves as writers and understand what we have to say is important. Practice. Practice. Practice.  
  • Pick your poetic devices. Poems that get attention are ones that incorporate simple, but powerful poetic elements. Repetition is a device that can help a writer generate exciting poems with just repeating a key phrase or image. Rhyming can enrich your diction and performance. (Check out other poetic devices while you’re at it.)
  • Performance. Spoken word poems are written to be performed. After your poem is written, practice performing the poem with the elements of good stage presence in mind.  It is important to maintain Eye Contact – Don’t stare at the floor, or hide behind a piece of paper/phone. From time to time, look into the eyes of people in the audience to capture their attention. Projection  is also crucial, so remember to speak loudly and clearly so that your voice can be heard from a distance. Enunciation helps the listeners to hear exactly what you say. Don’t mumble. Speak clearly and distinctly so that the audience can understand what you are saying. Facial Expressions  help animate your poem. You’re not a statue: smile if you’re reading something happy. Look angry if your poem is about anger. This might sound silly, but using the appropriate facial expressions help express various emotions in your performance. Gestures such as hand motions and body movements emphasize different elements of your performance. Choose the right gestures for your poem.

  • Memorization. Once you’ve memorized your spoken word piece, you can devote more time to your performance. Memorization allows you to be truly in touch with the meaning and the emotional content of your poem, even if you forget a word or a line you can improvise (freestyle), which is one of the most important elements of spoken word.
  • Power Poetry. Spoken word must be, well, spoken. To create an online performance (so that you can share it on Power Poetry, of course) check out our multimedia tip guide to bring your work to life.
  •  
    "Spoken Word is writing that is meant to be read out loud. Some examples of spoken word you might be familiar with are stories, poems, monologues, slam poetry, rap and even stand-up comedy. Spoken word is written on a page but performed for an audience and since it is performed, this poetry demonstrates a heavy use of rhythm, improvisation, rhymes, word play, and slang. It is more animated than more traditional forms of poetry. When writing a spoken word piece use words and phrases that project onto the minds of the listeners like vivid images, sounds, actions and other sensations. If your poem is rich with imagery, your listeners will see, smell, feel and maybe even taste what you're telling them. Here are some spoken word poems from our Power Poets."

Talking about disability: A guide to using appropriate language - 0 views

  •  
    Life for most people with mental or physical disabilities is vastly improved over what it was twenty or thirty years ago. The Americans with Disabilities Act and other federal and state laws assure that people with disabilities have the same basic rights as people without disabilities. Some things have been slower to change; namely, attitudes and perceptions about people with disabilities. Ignorance and discrimination can be serious impediments to achieving integration, productivity, and independence for people with disabilities. The use of outdated language and words to describe people with disabilities contributes greatly to perpetuating old stereotypes. No longer should we view people with disabilities as helpless or tragic victims. Awareness is the first step toward correcting this injustice. If public opinion about people with disabilities is to be brought up to date, the public needs to hear and learn to use appropriate language. It is especially important for the media, elected officials, public speakers, and others in leadership positions to portray people with disabilities sensitively and realistically. This is a guide to using descriptive words and language when talking to or about people with disabilities.

You Can Give a Boy a Doll, but You Can't Make Him Play With It - Christina Hoff Sommers... - 0 views

  • In April 2012, following the celebration of International Women's Day, the Swedes formally introduced the genderless pronoun "hen" to be used in place of he and she (han and hon).
  • Egalia, a new state-sponsored pre-school in Stockholm, is dedicated to the total obliteration of the male and female distinction. There are no boys and girls at Egalia—just "friends" and "buddies."
  • Classic fairy tales like Cinderella and Snow White have been replaced by tales of two male giraffes who parent abandoned crocodile eggs. The Swedish Green Party would like Egalia to be the norm: It has suggested placing gender watchdogs in all of the nation's preschools. "Egalia gives [children] a fantastic opportunity to be whoever they want to be," says one excited teacher.

  • Congenital adrenal hyperplasia (CAH) is a genetic condition that results when the female fetus is subjected to unusually large quantities of male hormones—adrenal androgens. Girls with CAH tend to prefer trucks, cars, and construction sets over dolls and play tea sets
  • Androgyny advocates like our Swedish friends have heard such stories many times, and they have an answer. They acknowledge that sex differences have at least some foundation in biology, but they insist that culture can intensify or diminish their power and effect.
  • Hunter College psychologist Virginia Valian, a strong proponent of Swedish-style re-genderization, wrote in the book Why So Slow? The Advancement of Women, "We do not accept biology as destiny ... We vaccinate, we inoculate, we medicate... I propose we adopt the same attitude toward biological sex differences."
  • As one Swedish mother, Tanja Bergkvist, told the Associated Press, "Different gender roles aren't problematic as long as they are equally valued." Gender neutrality is not a necessary condition for equality. Men and women can be different—but equal. And for most human beings, the differences are a vital source for meaning and happiness. Since when is uniformity a democratic ideal?
  • To succeed, the Swedish parents, teachers and authorities are going to have to police—incessantly—boys' powerful attraction to large-group rough-and-tumble play and girls' affinity for intimate theatrical play
  • Boys' imaginative play involves a lot of conflict and imaginary violence; girls' play, on the other hand, seems to be much gentler and more peaceful. But as Paley looked more carefully, she noticed that the girls' fantasies were just as exciting and intense as the boys—though different. There were full of conflict, pesky characters and imaginary power struggles.

Optimism and the Law of Attraction in Islam | Muslim Mind - 0 views

  • If you have hope in God, if you are certain that He will give you what’s good, then this is what He indeed will give you. But if you don’t, it’s like you’re saying to Him: I don’t trust You. God is the Generous, if you don’t have hope in His bounties, it only means that you don’t even believe He is really Generous. Do you realize how serious this is?
  • If you fear injustice, you forget that He is the Just. If you are confused and you don’t think you’ll find your way, you forget that He is the Guide. Remember that the reason to mention all that is to prove that a Muslim should be positive and focus on the positive; it’s how we Muslims should build our mind and our inner world.
  • Poverty is the promise of Satan, while forgiveness and abundance are God’s promise. Which promise are we to believe!? Remember that poverty is not only lack of money, which is only a manifestation; poverty is first of all a state of mind. Those who live in this state of mind are following and believing Satan instead of God.
  • ...3 more annotations...
  • One can be poor while having tons of money, whereas those who truly believe in God don’t hesitate to give, even if they are not so rich; it’s because they don’t have this poverty state of mind. That also explains why the Prophet used to give so much that his companions said he used to give in the manner of a person who fears no poverty; this is the example of the Prophet who wasn’t really rich as we know.
  • Let’s also look at some other indications of this Law of Optimism in Islam. The Prophet says “Ask God with firm conviction that He will answer your prayer.” Now imagine the state of mind of a person believing this saying of the Prophet. Imagine that you pray to God and ask Him for good and Halal things, then you go about in life certain that God’s mercy and generosity will give you what you wish. Imagine how much power this will give you, how much enthusiasm and how much hope! It’s true that God will not answer your prayer on the spot, not immediately, but you know He will, and your worries disappear.
  • The verse also links this attitude of asking for the bad to being hasty, notice that pessimism is usually connected to impatience as well; a pessimist loses hope as soon as he is challenged, whereas hope can’t be there without patience, because you don’t really expect the good to happen overnight. Reasonable and hopeful people realize that, so they are not hasty and impatient to have what they want.
  •  
    "Not long ago, a book was published, which had a great success, and it was entitled: "The Secret". It tries to give an answer to the previous questions, and it claims that the secret of happy and successful people lies in what is called, "the Law of Attraction." So what is the Law of Attraction, and do we have it anywhere in the teachings of our religion? I will tell you what the secret and what the Law of Attraction are, then I will explain that the belief in this so-called secret, which was told about by our Prophet and revealed in the Quran in the most simple and expressive ways, is in fact essential for a true Islamic life-style. It is essential for the inner life of a true Muslim and believer."

Why private schools are better than state - Parentdish UK - 0 views

  • beautiful buildings, steeped in history, the acres of immaculate grounds, the committed teachers, the exam results, the range of extra-curricula activities
  • Or maybe I'd simply prefer my children to mix with other children and parents whose speech is not punctuated with 'innit'.
  • I've taught in independent and state schools.
  • ...17 more annotations...
  • Not all teachers in state schools are work-shy; some are brilliant. But there are too many teachers who are not
  • In the last 10 years, only 17 out of 400,000 teachers in state schools were dismissed due to incompetence
  • In the state school, once-a-term staff meetings were something to get through as quickly as possible.
  • Parents thought nothing of looking me right in the eye at parents' evenings and reminding me that they were paying a lot of money for their child's education, so they expected results. I felt personally accountable. Do parents dare to tell a teacher in a state school that their taxes are paying their salaries, so shape up?
  • class size. I've taught classes with 15 pupils and classes with 35. Children in smaller classes feel more confident about contributing, and I had more time for them. I knew the name of every pupil in the school; I felt part of a close knit community and so did they.
  • Independent schools can't allow any child to slip through the net. At the weekly staff meeting we discussed each year group, flagging up any pupil who was struggling and an action-plan was devised. My department also had a weekly meeting where pupils were discussed.
  • Autonomy and accountability, that's what makes the independent system successful. Bad teachers just go.
  • Do independent schools simply hot-house children to get them through exams? Yes, and why not? But extra-curricular activities in independent schools are there to help children flourish, whether they are academically gifted or not.
  • Everyone connected with independent education expects success - the teachers, parents and children. There is no embarrassment about applying to Oxbridge or any Top Ten university, it's the norm. I accept that not all state schools have low expectations, but too many have an 'us and them' attitude towards top universities.
  • As an only child, I wanted my son to start in the prep system and carry on making friends for life
  • it gives parents power to provide the best for their children; you are the customer.
  • Until the state system is run on those lines, giving parents power, attracting the very best teachers with salaries and working conditions to match, then money will always buy better education and no one should feel guilty if they choose to buy it.
  • It could be deduced that we live in a society where your chance of success is determined before birth and that there is little reason to compete in 'the race of life' since some people are starting that race 150 yards in front and the top positions in our society are largely predetermined.
  • The trick is to find a school where the kids (and their parents) are committed to learning. Such schools do not have to be private, and the teachers in both private or state schools are generally excellent.
  • The grammar schools and the private schools are roughly comparable in academic performance. They outperform the comprehensives, for the simple reason for this is that the kids ending up in the comprehensives tend to be the ones who failed the 11+ examinations (i.e. their parents did not get them private tutoring, etc.).
  • The most stuck up children come out of private school.
  • This is the third time she has been back to private education and we feel we have much more of a say, as we are employing them to do a service and feel much more involved in her education.

Top 10 Ways to Manage Teacher Burnout - Combating Teacher Burnout - 0 views

  • Every time you think a negative thought reword it in your own mind. Even though this might seem silly, it is the core of internal happiness.
  • create an overall task list that you need to accomplish and store this someplace where you can check it over each week. Then make yourself a daily to-do list that is reasonable and doable. Try to limit yourself to 3-5 tasks that you can accomplish in one day. Then when you mark them off the list you can feel a sense of accomplishment, and you will have something to celebrate.
  • Each time something happens beyond your control, you can just ask for the courage to change the things you can, the strength to accept the things you cannot change, and the wisdom to know the difference.

  • While teachers cannot change much of what is thrown at them, they can change their own attitudes towards these challenges.
  • When your workday is done, you need to leave the stresses of it and the rest of your life behind, even if only for fifteen minutes. Relaxation and meditation can rejuvenate the body and the spirit.
  • laughter often is the best medicine. The natural endorphins that are released while laughing help bring us relief from the stresses of the world.
  • Burnout can often be caused by getting caught in a rut. While on the Internet, search for new lessons or materials to help you teach an upcoming topic. Outside of school, find something that you've always wanted to try but haven't done yet.
  • try not to bring home work every night. You might want to consider going into school early so that you can complete your paperwork.
  • everyone needs a good night's sleep to function properly the next day. I know that I personally need at least seven hours to be productive the next day. Figure this number out for yourself and make a date with your bed each night. Your body will thank you!

6 Women Scientists Who Were Snubbed Due to Sexism - 0 views

  • Several people posted comments about our story that noted one name was missing from the Nobel roster: Rosalind Franklin, a British biophysicist who also studied DNA. Her data were critical to Crick and Watson's work. But it turns out that Franklin would not have been eligible for the prize—she had passed away four years before Watson, Crick, and Wilkins received the prize, and the Nobel is never awarded posthumously.But even if she had been alive, she may still have been overlooked. Like many women scientists, Franklin was robbed of recognition throughout her career (See her section below for details.)
  • Pulsars are the remnants of massive stars that went supernova. Their very existence demonstrates that these giants didn't blow themselves into oblivion—instead, they left behind small, incredibly dense, rotating stars.Bell Burnell discovered the recurring signals given off by their rotation while analyzing data printed out on three miles of paper from a radio telescope she helped assemble.The finding resulted in a Nobel Prize, but the 1974 award in physics went to Anthony Hewish—Bell Burnell's supervisor—and Martin Ryle, also a radio astronomer at Cambridge University.The snub generated a "wave of sympathy" for Bell Burnell. But in an interview with National Geographic News this month, the astronomer was fairly matter-of-fact.
  • despite the sympathy, and her groundbreaking work, Bell Burnell said she was still subject to the prevailing attitudes toward women in academia.
  • ...9 more annotations...
  • "[And] it was extremely hard combining family and career," Bell Burnell said, partly because the university where she worked while pregnant had no provisions for maternity leave.
  • Born in 1922 in the Bronx, Esther Lederberg would grow up to lay the groundwork for future discoveries on genetic inheritance in bacteria, gene regulation, and genetic recombination.A microbiologist, she is perhaps best known for discovering a virus that infects bacteria—called the lambda bacteriophage—in 1951, while at the University of Wisconsin.Lederberg, along with her first husband Joshua Lederberg, also developed a way to easily transfer bacterial colonies from one petri dish to another, called replica plating, which enabled the study of antibiotic resistance. The Lederberg method is still in use today.Joshua Lederberg's work on replica plating played a part in his 1958 Nobel Prize for physiology or medicine, which he shared with George Beadle and Edward Tatum."She deserved credit for the discovery of lambda phage, her work on the F fertility factor, and, especially, replica plating," wrote Stanley Falkow, a retired microbiologist at Stanford University, in an email. But she didn't receive it.
  • Lise Meitner's work in nuclear physics led to the discovery of nuclear fission—the fact that atomic nuclei can split in two. That finding laid the groundwork for the atomic bomb.Her story is a complicated tangle of sexism, politics, and ethnicity.After finishing her doctoral degree in physics at the University of Vienna, Meitner moved to Berlin in 1907 and started collaborating with chemist Otto Hahn. They maintained their working relationship for more than 30 years.After the Nazis annexed Austria in March 1938, Meitner, who was Jewish, made her way to Stockholm, Sweden. She continued to work with Hahn, corresponding and meeting secretly in Copenhagen in November of that year.Although Hahn performed the experiments that produced the evidence supporting the idea of nuclear fission, he was unable to come up with an explanation. Meitner and her nephew, Otto Frisch, came up with the theory.Hahn published their findings without including Meitner as a co-author, although several accounts say Meitner understood this omission, given the situation in Nazi Germany."That's the start of how Meitner got separated from the credit of discovering nuclear fission," said Lewin Sime, who wrote a biography of Meitner.
  • Chien-Shiung Wu overturned a law of physics and participated in the development of the atom bomb.Wu was recruited to Columbia University in the 1940s as part of the Manhattan Project and conducted research on radiation detection and uranium enrichment. She stayed in the United States after the war and became known as one of the best experimental physicists of her time, said Nina Byers, a retired physics professor at the University of California, Los Angeles.In the mid-1950s, two theoretical physicists, Tsung-Dao Lee and Chen Ning Yang, approached Wu to help disprove the law of parity. The law holds that in quantum mechanics, two physical systems—like atoms—that were mirror images would behave in identical ways.Wu's experiments using cobalt-60, a radioactive form of the cobalt metal, upended this law, which had been accepted for 30 years.This milestone in physics led to a 1957 Nobel Prize for Yang and Lee—but not for Wu, who was left out despite her critical role. "People found [the Nobel decision] outrageous," said Byers.Pnina Abir-Am, a historian of science at Brandeis University, agreed, adding that ethnicity also played a role.
  • Rosalind Franklin used x-rays to take a picture of DNA that would change biology.Hers is perhaps one of the most well-known—and shameful—instances of a researcher being robbed of credit, said Lewin Sime.Franklin graduated with a doctorate in physical chemistry from Cambridge University in 1945, then spent three years at an institute in Paris where she learned x-ray diffraction techniques, or the ability to determine the molecular structures of crystals. (Learn more about her education and qualifications.)She returned to England in 1951 as a research associate in John Randall's laboratory at King's College in London and soon encountered Maurice Wilkins, who was leading his own research group studying the structure of DNA.Franklin and Wilkins worked on separate DNA projects, but by some accounts, Wilkins mistook Franklin's role in Randall's lab as that of an assistant rather than head of her own project.Meanwhile, James Watson and Francis Crick, both at Cambridge University, were also trying to determine the structure of DNA. They communicated with Wilkins, who at some point showed them Franklin's image of DNA—known as Photo 51—without her knowledge.Photo 51 enabled Watson, Crick, and Wilkins to deduce the correct structure for DNA, which they published in a series of articles in the journal Nature in April 1953. Franklin also published in the same issue, providing further details on DNA's structure.Franklin's image of the DNA molecule was key to deciphering its structure, but only Watson, Crick, and Wilkins received the 1962 Nobel Prize in physiology or medicine for their work.
  • Nettie Stevens performed studies crucial in determining that an organism's sex was dictated by its chromosomes rather than environmental or other factors.After receiving her doctorate from Bryn Mawr College in Pennsylvania, Stevens continued at the college as a researcher studying sex determination.By working on mealworms, she was able to deduce that the males produced sperm with X and Y chromosomes—the sex chromosomes—and that females produced reproductive cells with only X chromosomes. This was evidence supporting the theory that sex determination is directed by an organism's genetics.A fellow researcher, named Edmund Wilson, is said to have done similar work, but came to the same conclusion later than Stevens did.Stevens fell victim to a phenomenon known as the Matilda Effect—the repression or denial of the contributions of female researchers to science.Thomas Hunt Morgan, a prominent geneticist at the time, is often credited with discovering the genetic basis for sex determination, said Pomona College's Hoopes. He was the first to write a genetics textbook, she noted, and he wanted to magnify his contributions."Textbooks have this terrible tendency to choose the same evidence as other textbooks," she added. And so Stevens' name was not associated with the discovery of sex determination.
  • the first wife of Albert Einstein should be in this list. People know so little about her, and I think she deserves to be known. 
  • Vera Rubin, for accurate studies discovering dark matter.
  • How sadly ironic that the very woman who set the stage for the  DNA structure discovery, which in 1994 helped make it possible to genetically test and confirm BRCA carriers like Angelina Jolie and me (with familial cancer holocausts generation, after generation, after generation), did not have access the test that could have saved her life so she could go on with the research she loved and win a Nobel Prize.
