MTE 49409/28/09Directives for the TIMSS video commentary assignment (HW#3)View these lesson videos from Germany (volume & density), Japan (areas of triangles), and the US (angles) at http://mathedu.asu.edu/TIMSS/Comment on:1. Each lesson's coherence (the parts of the lesson and how they fit together). Explain the way it was coherent or the way in which it was not coherent.2. The ways in which these lessons reflect, or fail to reflect, the didactic triad that we discussed in class. Please write so that your sentences will be comprehensible even by someone who has not seen the videos. (That is, convey enough context about events in the video that the reader will still get your point even without having seen the video.)3. The extent to which the teacher engages his or her students in conceptual conversations and how the lesson is thereby affected.MTE 49409/28/09In-class activityFollow these directives for each part of the Japanese lesson, be specific and explicit:a) Describe the mathematical idea(s) that the teacher intended for students to learn(i.e., the math learning goals).b) Describe the problem(s) that students worked and the intended mathematical content addressed in those problems. c) Describe how the math content of a given problem fits with that of problems that students worked previously; how are the two related and what connections between them did the teacher hope students would make?d) Answer Question 1 (coherence) in terms of your descriptions of the math content (speak about how parts of a lesson fit together in terms of the math content of the problems worked by students and the intended math learning goals).Homework ( Due 10/05/09 )Apply the above approach to all three TIMSS lessons, and re-submit an assignmentthat provides your commentary about each lesson’s coherence in terms of the mathematical content of lessons and problems worked in those lessons.Note: The grade on this re-write will replace your original grade on this
