MENINGKATKAN MULTIREPRESENTASI FISIKA SISWA MELALUI PENERAPAN MODEL PROBLEM SOLVING SECARA KELOMPOK DISERTAI SOFTWARE PSIM DI SMK (Hukum Kelistrikan Arus Searah)
This paper reports the result of study about problem solving as groups with
software PSIM at vocational high school. The purpose of this research are: (1) to represent
the ability of verbal, mathematics, image, and graph physics at vocational high school; (2)
to examine the difference of students achievement physics between class treatment and
control. This research was pure experiment by using control group pre-test post-test design.
The data was collected by observation, interview, documentation and test. The result of
data collection was analyzed by descriptive and inferential statistics. The students pre-test
and post-test data was analyzed by normalized gain (Ng). The students achievement
physics data was analyzed by Independent Samples T Test. Based on the result of data
analysis, it can be concluded that: this research which using Ng analysis was knowable to
improve the ability of verbal representation, matemathical representation, image
representation and graphic representation of the students at vocational high school in
various scores 0,452 (medium), 0,474 (medium), 0,769 (high) and 0,907 (high); the result
of this research was significantly influence to students achievement and improvement.
