For the classroom discussion, an audience response system will be used to assess the discussion portion of the course. Students discuss their reasoning for their response with their peers. The results of each student’s response will count toward their class participation grade. Individual students will be graded based on the following two criteria: 1. Is the student participating in the discussion? 2. Did the student get the correct response? Based on how well the class responds to the question, the instructor will ask additional questions on this topic, review this topic, or move on to the next topic. Objective Examinations Example: 1.

Problem Solving Examinations Example: 1. Exam problem (problem solving with rubric grading): A rock is thrown straight up with an initial velocity of 20 m/s. What maximum height (in m) will the rock reach before starting to fall downward? (acceleration due to gravity is 9.8 m/s2). 2. Quiz problem (problem solving with rubric grading): A track star in the broad jump goes into the jump at 12 m/s and launches himself at 20˚ above the horizontal. How long is he in the air before returning to Earth? (g = 9.80 m/s2). Repeatable No Methods of Instruction Lecture/Discussion Distance Learning Lecture: A multimedia slide presentation is used to present the topic of centripetal acceleration in detail utilizing graphics and video segments for emphasis and clarity. Example problems are demonstrated by the instructor at appropriate times throughout the class lecture or live/recorded video. Students are always encouraged to ask questions in class or in the LMS video chat throughout the presentation. (Objectives: Rotational Motion 1-4). Several live or video demonstrations of rotational dynamics using actual equipment at appropriate times during the presentation provide more emphasis and clarity. Students are also given a complete set of lecture notes in advance and encouraged to ask questions throughout the presentation in class or through the LMS chat feature. (Objective: Rotational Motion 8 and 9). Distance Learning An audience response system is used to ask questions on the application of Newton's Law in order to assess the level of student understanding during lecture and recitation (problem solving session). Based on how well students respond to the questions, the instructor will ask additional questions on this topic, review this topic, or move on to the next topic. In the online format polling software will be used to administer the question for during live/recorded video sessions. (Objectives: Dynamics 1-7). In class, group problem solving activities are administered to assess student understanding. The activities are also designed to get students to verbalize physical concepts to each member in the group, identify concepts that affect a physical system, and to illustrate how to build physical models. The instructors role is to facilitate the activity. In the online modality this can be accomplished asynchronously using virtual groups or synchronously using a breakout groups feature of a live meeting software. Example: Suppose you connect three vessels of equal volume. The vessels are thermally insulated. You decide to connect the three vessels by placing thin tubes of negligible volume in between each container so that gas can flow from one vessel to the next when a stopcock between them is open. Initially, the pressure and temperature in each container is at the same value Po and To, respectively. The stopcocks between the vessels are opened, and thermal insulation is removed from two of the vessels. Then two vessels are surrounded by heat reservoirs so that their temperatures are maintained at 85To and 2To while the third remains at To. What is the final pressure of the system when mechanical equilibrium is reached? (Objectives: Thermodynamics 3,4) Typical Out of Class Assignments Reading Assignments 1.
