THE DIFFERENCE OF STUDENT'S CRITICAL THINKING AND RESULT STUDY BETWEEN LESSONS WHICH WAS USING GUIDED AND SEMI GUIDED INQUIRY ON GEOMETRICAL OPTICS SUBJECT STUDY IN SMA N 5 YOGYAKARTA

摘要

The purposes of this research was to know: (1) the difference of student'sudcritical thinking ability (CTA), (2) the difference of student's result study whichudwas pointed from concept capability between class of guided and semi guidedudinquiry model and also, (3) which was the better of both models that coulduddeveloping CTA and improving student's result study.udThis research used Nonequivalent Control Group Design eksperimenudmethode and Cluster Random Sampling technique which resulted two classes ofud20 students in each class (XB and XC). Class XB used guided inquiry model,udmeanwhile XC used semi guided inquiry model. Data was collected from pretestudand postest instrument and also CTA observation worksheet. The CTA and resultudstudy's difference was analyzed using ANAVA by significanty 5% and theudimprovement of result study was analyzed by Standar Gain method in every class.udStatistically, there was a difference of CTA in both class but neither ofudpostest result. The average of CTA in class XB was 71,33 meanwhile XC is 77,58.udThe average of result study in XB was 65,6 meanwhile XC was 70,2. The result ofudStandar Gain analysis showing the improvement of XB's concept attainment wasudmiddle with score 0,28, meanwhile XC was low. From that, semi guided inquiryudmodel's was better to developing CTA and improving student's concept capabiity.
