A GUIDED INQUIRY APPROACH-BASED PHYSICS PRACTICE MODEL TO IMPROVE STUDENTS’ CRITICAL THINKING SKILL

Abstract

This study aims to develop a guided inquiry approach-based physics practice model to
improve students' critical thinking skills. This study refers to the research and development
procedure model (R & D) by Borg and Gall. This study employs four phases namely
specification, operationalisation, piloting, and revision. To get appropriate model, a try out
was done based on five factors or steps which comprise (1) design, (2) subject of try out
(research) (3) type of try out data, (4) instrumentt of data collection, and (5) technique of
data analysis. The subjects of try out were 32 students which ware taken from the tenth
grade student’s of MAN 2 Mataram. The techniques of data collection in this study were
validation sheets, observation sheets, questionnaires and tests, while the technique of data
analysis using quantitative descriptive analysis. The model of being developed was
analyzed by three (3) aspects, namely: validity, effectiveness, and practicality. The results
of the validation of experts at 3.7 with a reliability of 96%, showing the developed model
is valid. Based on the first trial, the implementation syntax developed model of the observer
ratings obtained 97% done, it shows a model developed was practical. For N-Gain Student
critical thinking skills after attending the learning physics practice models based guided
inquiry 0.64 with moderate category, it demonstrates effective models developed for
improving critical thinking skills. Based on the above results it can be concluded that the
physics practice models based guided inquiry with a decent category.
