Analysis of critical thinking skills and scientific communication of students for SHM concepts assisted by Ispring quiz maker test instrument

The purpose of this study was to determine: (1) Students' critical thinking skills taught
using the Group Investigation and Direct Instruction learning model. (2) The ability of students
to think critically in terms of students' scientific communication skills in physics, especially the
concept of Simple Harmonic Motion (SHM) in springs after applying the learning model of
group investigation (GI) and direct instruction (DI) assisted by Ispring Quiz Maker media. The
experimental class is class X MIA 3 and the control class is class X MIA 4. The design of this
study is the True Experimental Design type Pretest-Postest Control Group Design. The
instrument consisted of: (1) formative critical thinking test (ispring quis maker test instrument),
(2) observation sheet of scientific communication of students, and (3) documentation. Data in
this study were analyzed using normalized gain values, one-party t-test, and analysis of students'
scientific communication skills. The results showed that: (1) students' ability to think critically
in learning using the Group Investigation model is better than Direct Instruction. (2) students
who have high scientific communication skills are better at critical thinking
