Wordle.net tag cloud of student advice to future semesters of Astronomy 210 students at Cuesta College, San Luis Obispo, CA.
Students have a weekly online reading assignment (hosted by SurveyMonkey.com), where they answer questions based on reading their textbook, material covered in previous lectures, opinion questions, and/or asking (anonymous) questions or making (anonymous) comments. Full credit is given for completing the online reading assignment before next week's lecture, regardless if whether their answers are correct/incorrect. Selected results/questions/comments are addressed by the instructor at the start of the following lecture.
(The following question was asked subsequent to, and then again following the first quiz of the semester.)
How difficult do you think Quiz 1 will be? (How difficult did you think Quiz 1 was?) (Graded for completion.)
(VD) Very difficult.
(D) Difficult.
(N) Neutral.
(E) Easy.
(VE) Very easy.
Student responses (pre-test, all responses)
Sections 70158, 70160
(VD) : 9 students
(D) : 36 students
(N) : 20 students
(E) : 5 students
(VE) : 0 students
Student responses (post-test, all responses)
Sections 70158, 70160
(VD) : 2 students
(D) : 27 students
(N) : 34 students
(E) : 6 students
(VE) : 1 student
Of the 70 students who had answered the pre-test question, and the 70 students who had answered the post-test question, 55 students had answered both the pre-test and post-test questions (while 15 students answered only the pre-test, and 15 students only answered the post-test question).
Student responses (pre-test responses only, no post-test responses, N = 15)
Sections 70158, 70160
(VD) : 2 students
(D) : 8 students
(N) : 4 students
(E) : 1 student
(VE) : 0 students
Student responses (no pre-test responses, post-test responses only, N = 15)
Sections 70158, 70160
(VD) : 1 student
(D) : 6 students
(N) : 7 students
(E) : 1 student
(VE) : 0 students
Of the 55 students who answered both the pre-test and post-test questions, 24 students had no change in their opinion, while 31 students changed their opinion.
Student responses (pre-test and post-test responders, no change in opinion, N = 24)
Sections 70158, 70160
(VD) : 0 students
(D) : 11 students
(N) : 11 students
(E) : 2 students
(VE) : 0 students
Student responses (pre-test and post-test responders, change in opinion, N = 31)
Sections 70158, 70160
(VD) : pre: 7 students; post: 1 student
(D) : pre: 17 students; post: 10 students
(N) : pre: 5 students; post: 16 students
(E) : pre: 2 students; post: 3 student
(VE) : pre: 0 students; post: 1 student
A Student t-test on all 55 students who answered both the pre-test and post-test questions (24 students with no change in their opinion together with the 31 students that changed their opinion) results in p = 0.0071, and thus there is a statistically significant difference between pre-test and post-test responses.
For the students who took both and responded differently to the pre-test and post-test questions, here were the shifts:
(VD) to (D): 4 students
(VD) to (N): 1 student
(VD) to (E): 1 student
(VD) to (VE): 1 student
(D) to (VD): 1 student
(D) to (N): 14 students
(D) to (E): 2 students
(N) to (D): 5 students
(E) to (D): 1 student
(E) to (N): 1 student
"Negative shifts" in opinion (e.g., towards difficult): 8 students
"Positive shifts" in opinion (e.g., towards east): 23 students
(Compare with the 24 students with no shifts in opinion.)
Thus there was significant shift towards positive opinions regarding the first quiz, after students received had their grades.
Students were given the opportunity to reflect upon their studying and offer advice to future students before taking their first quiz; responses are listed below verbatim, and summarized graphically as a Wordle at the top of this article.
