Description of Program The overall goal of this project was to increase student learning by introducing interactive learning activities in Chemistry 121 recitation sections and training the GTA’s to facilitate these activities effectively. The idea was to actively engage students in problem solving during the recitations. They could thereby gain an immediate feedback on whether they were developing the skills required for the course. By having the students work in groups, they would be encouraged to build their own learning communities. The recitation instructor’s role would be to guide the students to apply key concepts that had been introduced in lectures and labs. This approach toward learning stresses concepts rather than specific facts, and allows the course to link naturally to societal issues. Three steps were taken to carry out this transformation of the course: i Identify and train a “Lead GTA” in interactive learning techniques. The Lead GTA was chosen to be Matt Stoltzfus in Spring 2004, based on his previously superior performance as a TA in this and other courses in general chemistry. His training began in Summer 2004, and was conducted by John Parson and Andrew Heckler. It included reading of science education materials, discussions, and experience in mentoring new graduate students enrolled in Chemistry 701, Seminar in Teaching College Chemistry. The principal skill that the Lead GTA developed was being able to conduct an interactive recitation section in which the students solved carefully designed problems in small groups. ii Identify and/or develop materials for use during recitation sections. The materials used in the recitation sections were chosen to maximize group interaction, conceptual understanding, and learning of general problem solving skills. Prof. Patrick Woodward had already developed some materials for use in recitation sections. Other materials were developed by the Lead TA and instructors who were lecturing in Chemistry 121 in Autumn 2004. iii Assign the Lead TA to observe and advise other GTA’s on effective practices. The Lead GTA had half of the normal teaching assignment in Autumn 2004 and Winter 2005. He was assigned two recitation sections of Chemistry 121 to teach himself, but spent considerable time helping the instructors refine the activities, preparing and distributing solutions to all of the activities, and observing other GTAs while they discussed the activities in groups. Those discussions took place in weekly Chemistry 121 meetings that were attended by the instructors and all of the recitation GTA’s. They provided a means of assuring that every GTA in the course was prepared to use the activities in her/his own recitation sections. Also, faculty could obtain feedback from the GTA’s as to which activities were effective, which needed improvement and where students were having difficulties. The focus in Autumn 2004 was in writing new activities and having the GTA’s practice them before using them in their recitation sections. All 6 lecture sections of Chemistry 121 participated in the project in Autumn 2004. In Winter 2005, the activities that had been developed were refined, largely by the Lead GTA. All 4 lecture sections that quarter participated in the project. The weekly meetings were devoted mostly to giving specific advice on how to use the activities but also to gather feedback from the GTA’s. Most of the GTA’s involved had already been trained in the use of the activities in Autumn 2004. It had been hoped that the activities would be adopted for use in the two lecture sections of Chemistry 121 taught in Spring 2005, but the faculty teaching then chose not to require that their GTA’s use the activities for group work in their recitation sections. Also, Matt Stoltzfus was not available to assist with Chemistry 121 then. However the instructor for the lecture section of Chemistry 121 taught in Summer 2005 has chosen to use the same style of interactive recitation sections that were used in Autumn and Winter quarters. In fact she was one of the GTA’s that had taught in the course in those earlier quarters. The results of this GTA training program were publicized in a few ways: a report on the effectiveness of the teaching method was made to the Chemistry Department Committee for Improving General Chemistry Instruction, chaired by Dr. Woodward. This committee consists of 5 other faculty members and 2 staff members. Dr. Parson reported on results of the GTA training at the OSTEP meeting on Feb. 5, 2005, and also at the OSTEP Reception and Poster Session on May 25, 2005. 2. Itemized Budget Item FTAD provided ½ of Lead GTA salary for two quarters $5000 Dept of Chemistry provided Tuition and fees for Lead GTA The money available from FTAD was insufficient to employ a Lead GTA for the whole year. It would have been especially useful to have an additional $2500 to cover half of the salary in Spring 2005 for the Lead GTA, as the faculty assigned to teach Chemistry 121 in Spring 2005 were reluctant to adopt the use of interactive recitation sections without his assistance. 3. Assessment of Project Two forms of assessment were carried out. One looked at changes in students’ conceptual understanding of chemistry problems before and after taking the course. The other approach was to see how the students and GTA’s responded to this style of running the recitation sections. i Chemistry concepts test – pre- and post-course results. The American Chemical Society has published a set of concept exams which have been widely used for students who have taken high school level chemistry courses. They emphasize a student’s ability to visualize the underlying chemical ideas rather than to recall specific facts. Ten of these questions were selected which require the types of thought processes called for in the Chemistry 121-122-123 sequence. Since all of the Chemistry 121 sections adopted the new format for recitations, there was no control group of Autumn 2004 students available for comparison. However in an earlier study carried out by Dr. Heckler on two lecture sections of Chemistry 121, this same set of questions had been given to students before the course, and then several of the questions were imbedded in the final exams for the course. Those Chemistry 121 sections did not use the group activities in recitation sections and hence served as a good control group. One problem in making a comparison of results across different sections was that no common exams are used by the various instructors for the course. So different questions from the original set of ten were selected by instructors for use in their final exams. A table showing the outcomes from the concepts tests is given in Appendix A. A copy of the set of ten questions that were used can be obtained from Dr. Parson upon request. Six of the same questions were used in the control group and in the Autumn 2004 final exams, and five of the same questions were used in the control group and in the Winter 2005 final exams. Below is a summary of the results. • Traditional Recitations (control group) – Pre Correct 23.9% (6 question set); 24.7% (5 question set) – Post Correct 47.4% (6 question set); 46.3% correct (5 question set) • Interactive Recitations AU 2004 – 6 question set – Pre Correct 21.2% – Post Correct 57.3% • Interactive Recitations WI 2005 – 5 question set – Pre Correct 18.7% – Post Correct 51.8% It is apparent that students experiencing the interactive recitations ended up doing better on these questions. This happened even in Winter 2005 when students at the outset of the course were less prepared to answer the questions correctly. ii Evaluation of the recitation format by students and GTA’s. Two questionnaires were designed to assess the response of students and GTA’s to the interactive recitation sections. The questionnaire for students consisted of nine multiple choice questions, which are shown along with the results in Appendix B. By and large students responded favorably to the recitation format. For example the first question: “How much did working with other members of your group on the in-class activities help your learning?” had the following responses: (first percentage is for AU 2004 and second is for WI 2005) 1. 2. 3. 4. 5. 18%, 16% helped a great deal 29%, 24% helped a good deal 27%. 25% helped some 17%, 18% helped a little 9%, 17% was of no help The questionnaire for GTA’s queried the same aspects of the recitations as the student survey, and in addition, it asked other questions such as: “Would you want to teach in this recitation format again?” Responses from 19 of the 37 AU 2004 recitation GTA’s were the following: 1. 2. 3. 4. 5. 7 definitely 10 I would prefer this method 2 I am neutral 0 I would prefer the other method 0 definitely not This is a significant outcome since many of the GTA’s questioned also had experience teaching with the traditional recitation format. The complete questionnaire for the GTA’s is shown as Appendix C. In addition to the multiple choice questions, there were questions calling for written evaluations of various aspects of the course. The written responses of the GTA’s were distributed to the grant personnel and the lecturers involved in the course. They were discussed at a meeting on restructuring the General Chemistry curriculum organized by Dr. Woodward. Even though the same questionnaire was sent out electronically to the GTA’s in WI 2005, unfortunately no responses were obtained for that quarter. However, the weekly meetings with the GTA’s had allowed the grant personnel and lecturers ample opportunity to obtain feedback from them throughout the quarter on various aspects of the recitations. 4. Reflections on the Future i Continuation of the program. The GTA training program in the use of interactive recitation sections was judged to be a success. The activities which were developed will be used in the Chemistry 701 class that new Chemistry graduate students are currently taking. Faculty assigned to teach Chemistry 121 will be encouraged to make use of the activities in their own classes, and to develop new activities. One of the faculty members, Dr. Heather Allen who lectured in Chemistry 121 Autumn 2004, has already developed and tested a set of activities for Chemistry 122, which most of the science majors are required to take after Chemistry 121. Faculty will have to call on their own assigned GTA’s for help with refining and solving the activities, as Departmental support is not available to hire a Lead GTA on a continuing basis. However, the teaching expectations in the Department may be modified to include a mentoring requirement for graduate students after they move out of GTA positions. For many graduate students in Chemistry the transition from being a GTA to becoming a GRA can take place as early as the second year. ii Recommendations for changes. Several changes were already made in moving from the autumn to the winter quarter offering of Chemistry 121. These were done largely in response to concerns that were brought to the faculty’s attention during the training sessions and from the GTA questionnaire. One problem was that the take-home quizzes used in Autumn 2004 made it possible for cheating to go undetected. Even though warned not to work on the quizzes with the help of others, some students could very well have been doing just that. So in Winter 2005, a brief quiz was used in most of the recitations, but it was made short enough to allow ample time for the group activities. Also, students were assigned homework that now had to be handed in. Since students were permitted to work together on the homework, papers was checked mostly for effort rather than content. 5. Lessons Learned It is preferable to train GTA’s thoroughly just once in the use of a new component such as interactive recitations. If they are asked to go through training more than once, they will become bored and less open to change the second time they are involved. GTA’s who have helped previously with a course should be retained in future offerings of that course as long as possible, or at least they should be required to serve as mentors to GTA’s who are new to the course. GTA’s can be expected to run recitation sections according to a specific protocol, as long as the procedure they are to follow is thoroughly explained and justified. Students will not generally do unfinished class activities on their own unless some credit is allotted to them for doing so. Students should be expected to complete activity pages and hand them in at the next recitation section. In that way groups that were unable to complete the activities during a recitation would be strongly encouraged to work on them individually or in learning communities before the next recitation.

How did your students respond to working in groups? What are your thoughts about the size of the groups and process of assigning groups? 2. During the quarter various types of questions were tried on the recitation activities, ranging from simple application questions (i.e. plug and chug, such as what is the shape of this molecule, balance this reaction, what is the theoretical yield of this product, etc.), to concept questions that were meant to test the underlying principles (i.e. filling in the reaction box with the right type and number of molecules, etc.), to problems that linked chemistry to real world processes (i.e. rocket fuel problem, etc.), to open ended chemistry questions with more than one answer. Which types of questions were the most useful and what type of mix would you consider to be ideal for future recitations? 3. Do you think it would be useful to take some time at either the beginning or the end of the recitation to go over the basic concepts covered on the activities? If so when would you do it and how long would you spend on this activity? 4. To what extent do you think students left recitations with unanswered questions that could have been covered if you were able to spend most of the time addressing the students as one entire group? 5.
