The integration of simulation modeling system for student experiment and modeling ability evaluation

This research aims at developing and evaluating the computer simulation software of pendulum, and exploring junior high students' scientific modeling ability. Firstly, the researcher analyzed pendulum modeling software development. Secondly, after considering the validity of the software, and the assessments of the whole system by the experts in the field, this researcher revised the software to make it more suitable for the purposes of junior high students' pendulum modeling with computer simulation. Finally, purposes of this research are to contend the suggestions of application of the software for junior high science teacher, to synthetic development relevant software of pendulum modeling in this research, and to obtain the following conclusions:1. There are six kinds of variables of simulation pendulum: mass, length, angle, force, air-force, and width of string. Based on the modeling software systematic, the researcher needed to develop relevant software tools to help students' modeling, such as Time-recorder, grid chart and the film of Galileo's history of science.2. The fuzzy synthetic evaluation was implemented for assessing modeling ability. Five aspects, with totally 19 sub items together, are contained in the evaluation system, which can be regarded as the evaluation for student's modeling ability.3. Via the evaluation in discipline content, media interface and the user attitude, etc., this simulation software is suitable for the stage of junior high student pendulum modeling under the movement law, f = m a.
