THE EFFECT OF GUIDED INQUIRY MODEL ASSISTED BY PhET MEDIA ON STUDENTS’ LEARNING OUTCOMES

This study aimed to determine the learning outcomes of students who are given
treatment and determine the effect of PhET media guided inquiry learning model toward
the student’s learning outcomes of high school students. This type of research was quasi
– experimental research design with pretest-posttest control group design. The
population was all students of class XI IPA of SMAN 2 Medan in the 2022/2023
academic year. The samples were taken using purposive sampling technique and
obtained class XI IPA 3 as an experimental class and class XI IPA 1 as a control class.
The independent variable of guided inquiry learning model assisted by PhET media that
was imposed on the experimental class, while the student’s learning outcomes as the
dependent variable. The data were taken using multiple choice tests to measure students'
learning outcomes. The research hypothesis was tested using the hypothesist test with a
significant level of 0.5% aided by Excel and the results of the hypothesis test showed a
significant so Ha was accepted. Based on these results it can be concluded that there
was an effect of the treatment of guided inquiry model assisted by PhET media on the
students' learning outcomes at senior high school.
