[[alternative]]The Research of Applying educational Performance Evalucation to the Teaching Concept of Chemical Equilibrium

[[abstract]]This thesis is to apply educational performance evaluation to the teaching concept of chemical equilibrium. When learning chemistry, many senior high students often encounter difficulties and are frustrated. Moreover, it reduces the interest of learning chemistry that experiments education doesn't put into effect among most schools. The purpose of this thesis is dedicated to develop the educational evaluation instruments for simplified experiments. By observing students operating simplifiedexperiments with interesting and challenging evaluation instruments, the synthesis of this research is evaluated. After analyzing the data, we choice the topic of chemical equilibrium in order to simplify the design of experiments and analysis of chemical concept. 1. The results of pre- and post-tests indicate that students make greater progress of understanding the concept of chemical equilibrium. Thus, theapplicability of these teaching instruments innovated by this research can be expected. 2.Compared with pre- and post-tests both filled in by the treatment and control groups, there is no clear difference between by these two groups. The learning results are similar after teaching with either the instruments applied by this research or conventional ones. 3.As for the analysis between male and female students, this research does not approve any sexual difference on learning results. 4.The responses of students are found different from experimental operating and test results. This may be contributed from incorrect attitude of making experiments. On the other hand, it is convincing that students' learning is dominated by memorizing.
