9. Peer Facilitating Methodology Mentor-mentee cum peer facilitators session with Dr. JJ, Saturday for 3 hours. Concept reinforcement & problem solving with FCs. Sunday/Monday for 3 hrs Peer FCs meet with assigned peers (4 peers). Tue or Wed for 2 hours. Reinforcement + quiz: with all students. Thursday for 2 hrs New set of FC’s Reading assignment due

10. Peer Facilitating Methodology Mentor - mentee session  Facilitators (FC) (between 10 -15 pupil) meet me for about 3 hours on Friday.  A coordinator is appointed – those with highest CGPA.  Coordinators arrange for peers to meet together after session with me.  Responsible to assist peers to clarify confusing concepts  All FCs & other peers get to read a set of guided questions or simplified notes and very specific operational/outcome objectives on the week’s topic.simplified notes very specific operational/outcome objectives

11. Peer Facilitating Methodology Mentor - mentee session - Reinforcement  Facilitators (FC) meet me for about 4 hours on Sunday.  Some pizza/noodles/fried rice is served for lunch, MY TREAT.  Concepts are reviewed, added and discussed.  Selected examples or problems are solved.  Plenty of two-way discussion initiated by the mentor.

12. Peer Facilitating Methodology Peer Facilitating session Facilitators (FC) meet with their assigned peers (peers have submitted reading assignment).  Peers go through the specific outcome & evaluate their comprehension (pre).  Review & discussions (often knowledge dissemination) started by FC.  Peers go through the specific outcome again for post-analysis & they evaluate the FC.  I just go around from group to group to answer questions.

13. Peer Facilitating Methodology

14. Reinforcement With All Students  A lecture concentrating on overview by me.  Question (often forced answer rather than voluntary) & answer.  Evaluation - 15 minute quiz focusing on ability to draw, express, read tables and writing mathematical expressions.

15. Objectives - Review Specific outcomes I am confident that (Q in - Q out ) + (W in - W out ) + (E mass,in - E mass,out ) =  E sys, (kJ) I know that a refrigerator maintains a refrigerated space at a low T by removing heat (Q in =Q L ) from it. I am aware that a heat pump maintains a heated space at a high T by supplying Q out = Q H to the space. I know that for a reversible process, W in = W out, Q in = Q out for system and the surrounding after a cycle is completed.

16. Objectives - Review Specific outcomes I know that irreversibilities are caused by friction, non-isothermal heat transfer & non-quasi equilibrium movement. I realize that Carnot engines set the upper limit for the engines' performances.  max =  rev. COP R,max = COP R,rev. I know the Carnot principles for heat engines:  rev,1 =  rev,2 ; &  irr <  rev for engines between same T H & T L.

17. Objectives - Review Specific outcomes I am aware that the ratio of heat exchanges (Q H / Q L ) rev = T H / T L for Carnot engines. I can write: COP HP < COP HP,rev that is [ 1 / 1 - (Q L / Q H )] < [ 1 / {1 - (Q L / Q H ) rev }] = [ 1 / {1 - (T L / T H )}] = [T H /{T H - T L }]. I can write: COP R < COP R,rev that is [ 1 / {(Q H / Q L ) - 1}] < [ 1 / {(Q H / Q L ) rev - 1}] = [ 1 / {(T H / T L ) - 1}] = [T L / {T H - T L }]. I can write for a SPP:  th <  th,rev that is [ 1 - (Q L /Q H )] < [ 1 - (Q L /Q H ) rev].= [ 1 - (T L /T H )] = [{T H - T L } / T H ].

18. Objectives - Review Specific outcomes I know that the area under a T-s diagram will represent the heat transfer during an internally reversible process. I can write the entropy balance as: S in - S out + S gen =  S system, kJ/K or S in - S out + S gen =  S system., kW/K I can write the entropy balance as: s in - s out + s gen =  s system, kJ/kg K. For rev. process, S gen = S gen = s gen = 0. I know that entropy of a system can be changed by heat transfer, S heat, mass transfer, S mass & irreversibilities, S gen.; kJ/K

19. Notes - Review Review Energy must be conserved in any thermodynamics process

20. Notes - Review Specific outcomes For a stationary closed system, q –  =  u. For a stationary closed system undergoing a constant- pressure process, q –  =  h. For an open system that allows mass flow and undergoing a steady-state process, then the energy and the mass conservation must be obeyed and that there must be NO property change within the system’s boundary. Note that the mass and volume flow rate is related to the velocity of the moving mass.

21. Notes - Review Specific outcomes So, the energy balance for a steady-flow device is

22. Results & Discussion 4 Disadvantages äplenty of time must be dedicated to the following: òpreparing documentation: the peer guided notes (5-8 hrs), the self specific objectives (6- 10 hrs), the course outline (2-4 hrs). òGrading the reading assignment (2-4 hrs), grading the quizzes (4-6 hrs) òMentor-mentee session (6-8 hrs) òalways living by the hour & leaving not much time for anything else in a week

23. Results & Discussion 4 Disadvantages äplenty of time must be dedicated to the following: òmodifying lecture notes (2-3 hrs) òalways living by the hour & leaving not much time for anything else in a week ädocumentation has and are still evolving for the past 3 semesters (the peer review notes just begun this semester).

24. Results & Discussion 4 Advantages ästudents (FCs) get to learn the concepts in a very personal setting: òlistening and discussion takes place after they reading the peer review notes & specific learning outcomes òproblems are solved together, FC’s first then corrected by me ästudents are made to know the concepts before pee discussion and peer reinforcement through their summarized reading assignment

25. Results & Discussion 4 Advantages ästudents have their peer discussion in a very small group (3-4 students) ästudents are given the chance to participate in their discussion (although at times get frustrated ‘cos FC are not very reliable to answer questions) ämore active learning involving mentor- mentee, and among peers. äHighly probing & invoke students’ active participation (more than willing) during the reinforcement session

31. Concluding Remarks ( Mentor-mentee session is most liked by student ( Students are made to be ready before peer discussion through the summary of the reading assignments ( time spent and commitment on the lecturer’s part is extremely high until the documents and lectures are completely satisfactory

32. Concluding Remarks ( students interest in learning has improved tremendously even though most don’t take physics at any stage during their diploma program ( applicable to any class size as long as materials are carefully designed, and lecturers are willing to do away with their traditional method of passive learning (minimal students participation, ‘cos “we need to finish our syllabus”)
