Equilibrium Of Rigid Bodies Tutorial Homework

Physics 1110 Spring 2015

Tutorial Schedule: Assignments

On all but the last week, a tutorial will be performed in the blue tutorial workbook called “Tutorials in Introductory Physics” by McDermott and Shaffer.  This is a group activity but each student is expected to do his or her own work. This work is not handed in, but the TA grades each student’s participation.

After the first week, homework will also be due which students should hand in at the beginning of the recitation section. Most of these homeworks will be found in the red tutorial workbook called “Homework in Introductory Physics”, also by McDermott and Shaffer. These will be referred by the prefix HW with a range of pages numbers following. Students will need to neatly tear or cut these homeworks out of their workbooks prior to attending the recitation section. Typically, the homework is on the material covered in the previous tutorial.


Alternately, some homeworks will be constructed by the professors in this class and for those weeks a pdf will be provided in the table below. For those homeworks, print out the assignment and complete it, handing it in at the begining of your recitation section on the date indicated.

The schedule for the weekly tutorials and tutorial homeworks is as follows:

What? Guided-inquiry worksheets for small groups in recitation section of intro calculus-based physics. Instructors engage groups in Socratic dialogue. Worksheets use Elicit-Confront-Resolve model: Questions elicit known student difficulties and help students confront and resolve these difficulties.

Why? Each tutorial is designed to carefully walk students through overcoming specific student difficulties, and goes through a rigorous process of research and redesign to show that it leads to student learning. They can be effective even if instructors don't understand the research behind them.

Why not? These tutorials are designed for calculus-based physics courses, and may not work as well with other populations. Some researchers think that their elicit-confront-resolve approach may give students a sense that their intuition about physics is always wrong and lead to decreased self-efficacy.
