1. Open-Book Examinations What it is and what it is not Rocky K. C. Chang Department of Computing 15 October 2003

2. Rocky K. C. Chang, Department of Computing2 Why not OX? Mine is 100% continuous assessment. Mine requires a certain degree of memorization. The books would distract students during exams. I do not see the differences between closed and open book exams. It is much easier to design questions for closed-book exams. I am more comfortable with closed-book exams.

3. Rocky K. C. Chang, Department of Computing3 Why OX? Students would buy books. Students would spend more time on book reading. Students can stay away from the memorization exercise before exam. Students generally think that open-book exam a very fair assessment. Don’t have to worry whether students would have found out the questions beforehand. Don’t have to worry too much about plagiarism during exam.

4. Rocky K. C. Chang, Department of Computing4 In my opinion, OX is … Not to make students happier –Some don’t. Not exam questions as usual –More in-depth, probing questions Not a decision towards the end –Communicated in the first class Not about the form and style of examination –About the teaching strategy Not about making information available during exam –About communicating expectation throughout the course Not about open BOOKS –About openness in teaching and learning

5. Rocky K. C. Chang, Department of Computing5 Not to leave assessment alone Not assessment and teaching –Assessment as part of teaching Not assessment for the “final judgment” –Assessment for learning Not teach-and-then-assess –Teach-assess-teach-assess-teach- … Not assessment for the seen –Assessment for the unseen

6. Rocky K. C. Chang, Department of Computing6 Good vs bad assessments Assessment distinguishes students’ learning (normal distribution?). Assessment is congruent with teaching. Assessment covers the syllabus and major concepts. Assessment covers a range of skills (analytical, practical, communications, etc). Assessment discourages bad learning habits. Assessment effects good learning habits.

7. Rocky K. C. Chang, Department of Computing7 Why OX for me? Provide a thorough learning experience. Two approaches: barrier removal and enabling. First presupposition: closed-book exam is a barrier to thorough learning. –Instill insecurity: what if I miss …. –Encourage fact memorization and discourage understanding. –Limit the depth of the assessment. –Inconsistent environment.

8. Rocky K. C. Chang, Department of Computing8 OX can Remove the insecurity by making it a nonsecretive issue. Encourage to spend time only on understanding the course material. Probe for more in-depth understanding as a result of the last item. Minimize the discrepancy between the usual working environment and the examination environment.

9. Rocky K. C. Chang, Department of Computing9 Enabling through Assignments and tutorials –Past examination and test questions –Let’s-work-together-work –Drill a deeper understanding –Encourage the study group to work on them. Dynamic interaction Group-based learning 1-2 mid-term tests Hands-on class project

10. Rocky K. C. Chang, Department of Computing10 OX is everything Decided on OX before teaching. –Announce and explain it in the first class. –Guarantee no question recycling. My messages: –Communicate my expectations. –Show my seriousness in teaching. –Demonstrate my commitment in teaching. Enable students in the process

11. Rocky K. C. Chang, Department of Computing11 Impact on the students? Enjoy the exam more? Improve the learning attitude? Increase the class attendance? More attentive to the lectures and tutorials? Increase class participation? Change from memorization to understanding? Work harder? Stay away from plagiarism? Spend more time on reading the textbook? Study more with other students? Enhance the learning outcome? Increase the interest in the subject?

12. Rocky K. C. Chang, Department of Computing12 The most recent survey: I 1.The examination questions require a thorough understanding of the subject materials. 2.The examination questions are difficult. 3.The examination questions can accurately assess my understanding of the subject materials.

13. Rocky K. C. Chang, Department of Computing13 The most recent survey: I

14. Rocky K. C. Chang, Department of Computing14 The most recent survey: II 4.The solutions to the assignments and previous examination questions are helpful for the exam preparation. 5.The books and other materials that you brought are helpful. 6.The time given for the examination is adequate, i.e., given 1-2 more hours would not help.

15. Rocky K. C. Chang, Department of Computing15 The most recent survey: II

16. Rocky K. C. Chang, Department of Computing16 The most recent survey: III 7.I still prefer this kind of open-book examinations. 8.I think I have achieved my expected grade indicated in the first-class survey. 9.Overall, I enjoy taking this course.

17. Rocky K. C. Chang, Department of Computing17 The most recent survey: III

18. Rocky K. C. Chang, Department of Computing18 Other comments Always critical questions, so exciting, but frustrating. Strongly agree on Q.1 and 2. This can really distinguish very good students from average students. Open book exam is very time consuming. Open book exam works like assignment. Can consider close book exam with easier questions and less time. I found that I could learn a lot during this exam. Also, I realize what we should spend more time on it. Overall, I think this kind of examination is really interesting. Many questions are not easily be found in the book, really need to understand.

19. Rocky K. C. Chang, Department of Computing19 What have I gained? I have compiled a set of good problems. I am more thorough in my teaching. I have a better understanding of the students’ learning difficulties. I have learned more during the time of designing new questions. I can gradually increase the depth of my teaching. I see my students put more effort in understanding. I have stayed alive in my teaching.

20. Rocky K. C. Chang, Department of Computing20 What does OX (not) achieve? Not important: –The books, notes, assignment solutions available to the students Important: –Get rid of the fear of losing out to those good memorizers. Very important –Encourage students spend to more time on understanding. Utmost important –Cultivate a passion for thorough learning.

21. Rocky K. C. Chang, Department of Computing21 A final question Does our teaching produce students with an open mind? –Do they question? –Do they challenge? –Do they counter-propose? –Do they innovate? OX is an instrument to cultivate an open environment for teaching and learning. –Transparent teaching

22. The course promotes independent thinking rather than memorizing. This is the most special thing throughout the two years of U-life. - A student’s comment
