  • 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,

  • 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.

  • the assumption that there is a single established body of mathematical skills that everyone needs to know to be prepared for 21st-century careers. This assumption is wrong. The truth is that different sets of math skills are useful for different careers, and our math education should be changed to reflect this fact.
  • Today, American high schools offer a sequence of algebra, geometry, more algebra, pre-calculus and calculus (or a “reform” version in which these topics are interwoven). This has been codified by the Common Core State Standards, recently adopted by more than 40 states. This highly abstract curriculum is simply not the best way to prepare a vast majority of high school students for life.
  • A math curriculum that focused on real-life problems would still expose students to the abstract tools of mathematics, especially the manipulation of unknown quantities. But there is a world of difference between teaching “pure” math, with no context, and teaching relevant problems that will lead students to appreciate how a mathematical formula models and clarifies real-world situations.
  • ...4 more annotations...
  • For instance, how often do most adults encounter a situation in which they need to solve a quadratic equation? Do they need to know what constitutes a “group of transformations” or a “complex number”? Of course professional mathematicians, physicists and engineers need to know all this, but most citizens would be better served by studying how mortgages are priced, how computers are programmed and how the statistical results of a medical trial are to be understood.
  • Imagine replacing the sequence of algebra, geometry and calculus with a sequence of finance, data and basic engineering.
  • Traditionalists will object that the standard curriculum teaches valuable abstract reasoning, even if the specific skills acquired are not immediately useful in later life. A generation ago, traditionalists were also arguing that studying Latin, though it had no practical application, helped students develop unique linguistic skills. We believe that studying applied math, like learning living languages, provides both useable knowledge and abstract skills.
  • In math, what we need is “quantitative literacy,” the ability to make quantitative connections whenever life requires (as when we are confronted with conflicting medical test results but need to decide whether to undergo a further procedure) and “mathematical modeling,” the ability to move practically between everyday problems and mathematical formulations (as when we decide whether it is better to buy or lease a new car).

    From rockets to stock markets, many of humanity's most thrilling creations are powered by math. So why do kids lose interest in it? Conrad Wolfram says the part of math we teach - calculation by hand - isn't just tedious, it's mostly irrelevant to real mathematics and the real world. He presents his radical idea: teaching kids math through computer programming.

It's prospective parent information day, and you make the trek to San Francisco's South of Market neighborhood. You walk up to the second floor of the school, file into a glass-walled conference room overlooking a classroom, and take a seat alongside dozens of other parents who, like you, feel that public schools-with their endless bubble-filled tests, 38-kid classrooms, and antiquated approach to learning-just aren't cutting it. At the same time, you're thinking: this school is kind of weird. On one side of the glass is a cheery little scene, with two teachers leading two different middle school lessons on opposite ends of the room. But on the other side is something altogether unusual: an airy and open office with vaulted ceilings, sunlight streaming onto low-slung couches, and rows of hoodie-wearing employees typing away on their computers while munching on free snacks from the kitchen. And while you can't quite be sure, you think that might be a robot on wheels roaming about. Then there's the guy who's standing at the front of the conference room, the school's founder. Dressed in the San Francisco standard issue t-shirt and jeans, he's unlike any school administrator you've ever met. But the more he talks about how this school uses technology to enhance and individualize education, the more you start to like what he has to say. And so, if you are truly fed up with the school stat

  • Economists are trying to measure a home computer’s educational impact on schoolchildren in low-income households.
  • little or no educational benefit is found. Worse, computers seem to have further separated children in low-income households, whose test scores often decline after the machine arrives, from their more privileged counterparts.
  • few children whose families obtained computers said they used the machines for homework. What they were used for — daily — was playing games.
  • ...4 more annotations...
  • “Scaling the Digital Divide,” published last month, looks at the arrival of broadband service in North Carolina between 2000 and 2005 and its effect on middle school test scores during that period. Students posted significantly lower math test scores after the first broadband service provider showed up in their neighborhood, and significantly lower reading scores as well when the number of broadband providers passed four.
  • The expansion of broadband service was associated with a pronounced drop in test scores for black students in both reading and math, but no effect on the math scores and little on the reading scores of other students.
  • THE one area where the students from lower-income families in the immersion program closed the gap with higher-income students was the same one identified in the Romanian study: computer skills.
  • How disappointing to read in the Texas study that “there was no evidence linking technology immersion with student self-directed learning or their general satisfaction with schoolwork.”

    Traditional methods of teaching maths have more in common with how we programme a computer that what we might do if we wanted to engage our students in mathematical thinking. We shouldn't be overly surprised then when our students consider mathematics to be all about learning a set of rules that they need to apply in the right order so as to output the correct response. But is there a better way?

    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."

    "Crickets are small programmable devices that can make things spin, light up, and play music. You can plug lights, motors, and sensors into a Cricket, then write computer programs to tell them how to react and behave. With Crickets, you can create musical sculptures, interactive jewelry, dancing creatures, and other artistic inventions -- and learn important math, science, and engineering ideas in the process. Crickets are based on more than a decade of NSF-funded educational research. Lifelong Kindergarten researchers collaborated with the LEGO company to create the first "programmable bricks," squeezing computational power into LEGO bricks. This research led to the LEGO MindStorms robotics kits, now used by millions of people around the world. While LEGO MindStorms is designed especially for making robots, Crickets are designed especially for making artistic creations. Crickets were refined in collaboration with the Playful Invention and Exploration (PIE) museum network, and are now sold as a product through the Playful Invention Company (PICO)."
