Walchand Institute of Technology, Solapur (www. witsolapur. org) About this constructor • Transformation defines some change in object in terms of shape, size, location, etc. • Various types of transformations such as translation, scaling, rotation, shearing, reflection, etc. • When a transformation takes place on a 2 Dimension plane, it is called 2 D Geometric transformation. • Transformations play an important role in computer graphics to reposition the graphics on the screen and change their size or orientation.

Walchand Institute of Technology, Solapur (www. witsolapur. org) In-class Activity Design -2 Active Learning activity(ies) that you plan to do Real world problem solving using. • Think-Pair-Share Conceptual Clarification using • Peer Instruction IDP in Educational Technology, IIT Bombay 10

Walchand Institute of Technology, Solapur (www. witsolapur. org) In-class Activity Design -2 Peer Instruction Strategy – For analyzing and understanding the concept. Q 1: Translate the triangle with vertices A(1, 1), B(4, 1) and C(4, 3) by 2 units in X and Y direction and Magnify it twice. Q 2. Perform a 90° rotation of a triangle A(1, 1), B(4, 1), C(4, 3) IDP in Educational Technology, IIT Bombay 11

Walchand Institute of Technology, Solapur (www. witsolapur. org) In-class Activity Design -2 Peer Instruction Strategy – What Student Does § For each question they will first vote individually. § Then they will discuss with peers and come to consensus. § Listen to instructors explanation. IDP in Educational Technology, IIT Bombay 12

Walchand Institute of Technology, Solapur (www. witsolapur. org) In-class Activity Design -2 TPS Strategy – Think (~15 minutes) Think individually and Solve the problem. Pair (~7 minutes) Instruction: Now pair up and compare your answers. Agree on one final answer. While students are pairing and discussing, instructor goes to 2~3 sections to see what they are doing. IDP in Educational Technology, IIT Bombay 13

Walchand Institute of Technology, Solapur (www. witsolapur. org) In-class Activity Design -2 TPS Strategy- (10 Mins) • Instructor asks a group to share their answer with class and see whethere are different answers. After sharing is done, instructor gives feedback on the correct solution. • In the next iteration of TPS, in the Think Phase we ask students to compare their answers. • In the pair phase we ask students to compare the answers. • In the share phase again the different answers are sought. IDP in Educational Technology, IIT Bombay 14

Walchand Institute of Technology, Solapur (www. witsolapur. org) In-class Activity Design -2 Justify why the above is an active learning strategy • In both the above questions, student will solve the problem. • They are required to think deeply about the content they were familiarized in out-of -class and do higher order thinking. • There is also feedback provided (either through peer discussion or instructor summary) IDP in Educational Technology, IIT Bombay 15
