• Questionnaires – Learners got to fill out a questionnaire at the end of each of the five training days. (See Appendix O to find the five questionnaires.) 4.05.02 Mapping Assessment Items to Instructional Objectives Every exercise question and every question on each of the tests has been mapped to one or more instructional objectives. This is in keeping with the spirit of objectives- oriented evaluation strategy. The matrices illustrating these mappings are located in Appendix R. These matrices, as previously mentioned, also have a difficulty level corresponding to Bloom’s taxonomy assigned to each exercise and test question. (See Appendix Q.) 68
Chapter 5: Experiment Design 5.01 Overview of the Experiment After designing and developing training material for domain testing, I conducted two rounds of pilot studies. These were basically formative evaluations that lead to immense revision and refinement of the training material content, my instruction and the way I was organizing the training material. Once I felt the training material was polished enough to be used in the real experiment, I conducted actual training sessions using the revised training material with 23 learners. I started with 18 learners in my actual experiment. Each training period lasted for five days, starting on a Monday and ending on a Friday. The entire training period totaled 18 hours. The learners took a paper-based pretest on the first day following a brief introductory lecture on domain testing. The pretest was open book and the learners were given reference materials to consult during the test. On the second, third and fourth training days, the learners were subject to lectures that involved demonstration of examples that addressed one or more instructional objectives. They were then required to solve exercises based on what they learned in the lecture. The strategy was to alternate between examples and exercises. The learners could refer to the reference materials and lecture slides to solve exercises. However, they were not allowed to take the reference materials home. This helped control the amount of time subjects actually spent on the material during the week. We didn't want the variability of some students working for several hours per night on the material while others worked only in class. We also wanted to reduce the chances of learners scheduled to attend future training sessions being exposed to the training material, which could influence those future learners’ performance. On the fifth and final training day, the learners were required to take two posttests. One was a paper-based test which was equivalent to the pretest, and the 69
