  • What would an exceptional middle and high school computer science curriculum include?
  • This isn't a complete answer, but one thing the very first introductory classes should require is that the students turn off all their electronic computers and actually learn to walk through  algorithms with a computer that exists only on paper. (Or, I suppose, a whiteboard or a simulator.) This exercise would give the students a grounding in what is going on inside the computer as a very low level.My first computer programming class in my Freshman year of high school was completely on paper. Although it was done because the school didn't have much money, it turned out to be very beneficial.Another class I had in high school, that wouldn't normally be lumped into a Computer Science curriculum but has been a boon to my career, was good old Typing 101.
  • If you followed the CS Unplugged curriculum your students would know more about CS than most CS grads:http://csunplugged.orgIt's a really great intro to basic computer science concepts and very easy for students to understand.  Best of all you don't even need a computer per student if your school doesn't have the budget,
  • ...6 more annotations...
  • For younger students, I think that the ability to make something professional-looking, like a real grown-up would, is paramount.  Sadly, I think this means that LOGO and BASIC aren't much use any more*.
  • So, we have a few choices.  You can try to write phone apps that look just like real phone apps, design interactive websites that look just like real interactive websites, or do something with embedded systems / robotics.  Avoid the temptation to make these things into group projects; the main thing every student needs to experience is the process of writing code, running it, debugging it, and watching the machine react to every command.
  • It is important to consider what an 11 to 18-year old is familiar with in terms of mathematics and logical thinking. An average 11-year old is probably learning about fractions, simple cartesian geometry, the concept of units, and mathematical expressions. By 15, the average student will be taking algebra, and hopefully will have the all-important concept of variables under his/her belt. So much in CS is dependent on solid understanding that symbols and tokens can represent abstract concepts, values, or algorithms. Without it, it's still possible to teach CS, but it must be done in a very different way (see Scratch).
  • At this point, concepts such as variables, parenthesis matching, and functions (of the mathematical variety) are within easy reach. Concepts like parameter passing, strings and collections, and program flow should be teachable. More advanced concepts such as recursion, references and pointers, certain data structures, and big-O may be very difficult to teach without first going through some more foundational math.
  • I tend to agree strongly with those that believe a foundational education should inspire interest and enforce concepts and critical thinking over teaching any specific language, framework, system, or dogma.
  • The key is that the concepts in CS aren't just there for the hell of it. Everything was motivated by a real problem, and few things are more satisfying than fixing something you really want to work with a cool technique or concept you just learned.

    CS Unplugged is a collection of free learning activities that teach Computer Science through engaging games and puzzles that use cards, string, crayons and lots of running around. The activities introduce students to underlying concepts such as binary numbers, algorithms and data compression, separated from the distractions and technical details we usually see with computers. CS Unplugged is suitable for people of all ages, from elementary school to seniors, and from many countries and backgrounds. Unplugged has been used around the world for over fifteen years, in classrooms, science centers, homes, and even for holiday events in a park!

  • Attracting females is key to the future of computer science, Rodger says. In 2008, only 11.8 percent of U.S. bachelor's degrees in computer science went to women, according to the Computing Research Association. And Duke's showing is hardly better, said Rodger, who is trying to turn that around by making programming fun to learn.

    Asa Spencer of the Thomas B. Fordham Institute writes in the Education Gadfly Weekly: "Traditionalists cringe, tech buffs rejoice: This latest NAEP writing assessment for grades eight and twelve marks the first computer-based appraisal (by the "nation's report card") of student proficiency in this subject. It evaluates students' writing skills (what NAEP calls both academic and workplace writing) based on three criteria: idea development, organization, and language facility and conventions. Results were predictably bad: Just twenty-four percent of eighth graders and 27 percent of twelfth graders scored proficient or above. Boys performed particularly poorly; half as many eighth-grade males reached proficiency as their female counterparts. The use of computers adds a level of complexity to these analyses: The software allows those being tested to use a thesaurus (which 29 percent of eighth graders exploited), text-to-speech software (71 percent of eighth graders used), spell check (three-quarters of twelfth graders), and kindred functions. It is unclear whether use of these crutches affected a student's "language facility" scores, though it sure seems likely. While this new mechanism for assessing kids' writing prowess makes it impossible to track trend data, one can make (disheartening) comparisons across subjects. About a third of eighth graders hit the NAEP proficiency benchmark in the latest science, math, and reading assessments, compared to a quarter for writing. So where to go from here? The report also notes that twelfth-grade students who write four to five pages a week score ten points higher than those who write just one page a week. Encouraging students to put pen to paper (or fingers to keyboard) is a start."

      This is where I think textbooks companies need to lead. Customers typically only want more of the same, more of what has worked in the past, more of what has a track record. They dont' necessarily think beyond and/or have the luxury of being visionaries.

    At Empire High School in Vail, Ariz., students use computers provided by the school to get their lessons, do their homework and hear podcasts of their teachers' science lectures. Down the road, at Cienega High School, students who own laptops can register for "digital sections" of several English, history and science classes. And throughout the district, a Beyond Textbooks initiative encourages teachers to create - and share - lessons that incorporate their own PowerPoint presentations, along with videos and research materials they find by sifting through reliable Internet sites.

    "Engineering is the "silent E" in STEM subject areas. While science, mathematics, and technology are often topics of content area lessons, engineering is often ignored. However, engineering is inclusive of all STEM subjects because engineers use science, mathematics, and technology to solve problems. Engineering careers are diverse, spanning many different technologies and disciplines, such as agricultural engineering, aerospace engineering, computer engineering, mechanical engineering, and chemical engineering."

  • Although many old and recent studies conclude that people understand what they read on paper more thoroughly than what they read on screens, the differences are often small. Some experiments, however, suggest that researchers should look not just at immediate reading comprehension, but also at long-term memory.
  • When taking the quiz, volunteers who had read study material on a monitor relied much more on remembering than on knowing, whereas students who read on paper depended equally on remembering and knowing.

  • Subconsciously, many people may think of reading on a computer or tablet as a less serious affair than reading on paper. Based on a detailed 2005 survey of 113 people in northern California, Ziming Liu of San Jose State University concluded that people reading on screens take a lot of shortcuts—they spend more time browsing, scanning and hunting for keywords compared with people reading on paper, and are more likely to read a document once, and only once.
