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.
Keywords: Physics Practicum Model Based Guided Inquiry, Critical Thinking Skills.
