Since 50% of all the tests and also the final will incorporate problem-solving skill based on conceptual understanding, your comprehension of the subject matter is highly significant before you try to solve any problems. Hence, you need to practice doing the problems while brushing your understanding of the subject matter. The other 50% will concentrate on sketching, drawings, labelling, and writing down concepts both in your own words and its mathematical representation. Your ability to sketch, label and draw will determine how much you understood the subject matter and in most cases the questions that are asked of you and will also indicate your success in the course. Lecturer: Dr. J.J. Page 3 of 4 Semester May 2001 – Oct 2001 @ Hakcipta Fakulti Sains Gunaan, UiTM, Shah Alam ASSESSMENT TESTS READING ASSIGNMENT QUIZ PROJECT (Peer-Facilitating) FINAL EXAM 3 x 10% 8 x 1% 6 x 2% 1 x 10% 1 x 40% = 30% = 8% = 12% = 10% = 40% READING ASSIGNMENT ALL the assignment must be submitted no later than 3:00pm on Mondays. Your handwriting must be legible. Remember that this is only a summary of the chapter. Hence, I anticipate you to draw, label, draw again and write down conceptual ideas. In addition, the mathematical representation for how the concepts are related and maybe some derivation on how to represent the concepts mathematically, must also be included, where applicable. DO NOT COPY ALL THAT YOU SEE IN YOUR TEXTBOOK. SUMMARIZE THEM. A good summary should not be more than 3 page long with lots of drawings and labeling or concept/mind mapping. You receive credit for each assignment that you submit. PROJECT (PEER FACILITATING) Assessment Components include the following: i) Preparation before and during consultation (group scoring), and attendance whether as a facilitator or as a peer. – 5% ii) Peer evaluation during discussion with peers (individual scoring) –2 X 2.5% = 5% FORMAT: 1) Ten (DIC) and five (BSAC) groups will be formed and depending on the class size, a group may consist of between three and four members. 2) Each student will be assigned to do peer tutoring (facilitating) ONLY TWICE during the semester. This works really well if there are four members in each group but we will make do with whatever numbers we have. Procedure: a) Group members are selected randomly by me. b) Group coordinators will be selected by me based on CGPA. c) Each group will receive the assigned topic two weeks after the semester begins. d) Group leaders will then discuss and distribute reading responsibilities to group members. e) Group members will then meet to put together materials and methods they will use to facilitate discussion with peer students. f) On Fridays & Saturdays or Sundays, groups doing the tutoring the following week will see me to discuss what needs to be prepared. During this hour, we will go through your preparation (the concepts involved, the graphs or drawings and labeling that are required, the reasoning for a process or relationship between concepts, and the mathematical representations of the relationships), your understanding, your needs and your lacking. Group members are to read the materials before seeing me. We will be using the operational objectives & facilitator’s notes that can be downloaded from my website at www.itm.edu.my/acaprg/fsg/drjj1.html. A password is required & an Acrobat Reader will have to be installed on the computer you use to access the internet. g) Facilitating will be on Tuesdays (DIC) for two hours. Your role is to start and guide discussion among members and NOT TO TEACH. In addition to sharing concepts with your peers, you will also need to work on some examples and exercise problems during this session. Before the session begins, your students would have already evaluated themselves by using the operational objectives. In addition, peers in your group will also evaluate you using a special form. Hence you must make sure to complete your session within 90 minutes. All sessions will begin on time (2:10pm). h) Thursdays are designated for reinforcement (lecture/discussion) led by me with all students. In addition, there will be quizzes (as designated on pages 1 – 3 of this outline).
