- Well, of course the NRC accused AP Physics B of being a mile wide and an inch deep - it's the poster child for it!
- That seems to have been a trigger for similar redesigns of other AP courses
- Interesting, but not really surprising, bar graph of the results of surveys of colleges about coverage of topics in different semesters
- Good seven big ideas of physics: don't have time to get them down, but... Systems have properties, interactions are forces, waves mediate p and E exchange, math is useful for describing nature, didn't get the rest
- Tradeoff: reduced credit for students scoring well on the B exam if it's split, but increased access (especially given that they always recommended B being a second year course)
- I might like this...
- It might not align well with some state graduation requirements (like California)
- They're promising a detailed curriculum framework, including boundaries and depth
- Adding inquiry and conceptual reasoning
- Proposed release date: Fall 2014
- Nice question: "I was at one of these meetings two years ago, and I saw a similar talk, that said that it would be coming out in two years."
- They're saying that having B1 (mechanics) as a first course would prepare students to do well with both parts of AP C in a second year. The idea of having an option for the B1 kids to take a second year (particularly those without the calculus prereq.) of physics is good, though I don't have a free prep to teach it!
- Now we're talking about the curriculum
- They're saying that the curriculum isn't a sequence or a pacing guide, but instead a framing of the seven big ideas
- Each big idea has some 'enduring understandings' subordinate to it
- Below that, there's 'essential knowledge' (more than just facts, allegedly) and 'science practices: inquiry and reasoning'
- Below that, nougat
- A second shot at Big Ideas: "Objects and systems have properties such as mass and charge. Systems may have internal structure," "Fields existing in space can be used to explain interactions," "that force/interaction one", "missed one", ""Changes that occur as a reult of interactions are constrained by conservation laws," "Waves can transfer E and p from one location to another without the permanent transfer of mass and serve as a math. model for the desc. of other phenomena," "The math. of probability can be used to describe the behavior of complex systems and to interpret the..." Sorry - I type too slowly
- The division here lends itself pretty well to SBG
- The "science practices" are being shared among different AP science courses - that'll help out our benchmarking!
- Some examples: models/representations, math, questioning, plan and implement data collection, three or four more; they says that they're available on the AP site, since they're common to all courses
- Each of those comes with several skills used to demonstrate the desired practice
- Essential knowledge and science practices are alleged to collide inelastically and usefully to the teacher to become learning objectives
- They've promised that there are no required labs about 6 times
- An unfortunate example of one of the Essential Knowledge items: "A force exerted on an object is always due to the interaction of that object with another object." Will there be a list of underlying assumptions, since there's a big one behind that statement?
- Rotation being added (angular kinematics and momentum, torque without angular acceleration)
- For some reason... intro circuits is in the AP 1 course.
- It's starting to look a bit more packed now: kinematics, dynamics, p, E, oscillations, waves and sound, rotation, statics, electric circuits
- C courses left untouched (at this point)
- Symbolic problem-solving, lab and analytical skills, experimental design, more reasoning questions, deeper conceptual questions, error analysis, much more writing to justify understanding: changes to the exam
- Overall, it seems like a good pitch. We'll see how it plays out (can you tell that I'm skeptical of the College Board? :)
- Afterwards, a good story when talking to the presenter about the (grossly disfunctional) AP audit process: one of the teachers that wrote one of the sample syllabi on the site (which I basically had to copy to get them to accept my audit proposal) had her syllabus rejected. :)

Winter Meeting: Monday Night
Here's an interesting one - an hour on the AP Physics B Course and Exam redesign (about time!):
