Application of Inquiry Based Learning Model Using Stem Approach to Reduce Students' Intrinsic Cognitive Load

Abstract

This study is an experimental research using a quasi-experimental design with the type of non-equivalent control group pretest-posttest. This research aims to reduce Intrinsic Cognitive Load (ICL) through Inquiry Based Learning (IBL) model based STEM approach. This research was conducted at SMA Negeri 1 Seputih Banyak with the research subjects of class X IPA 1 students and X IPA 4. An data Intrinsic Cognitive Load obtained from essay the pretest-posttest (Task Complexity worksheet). Cognitive load test data analysis was performed using the data normality test, N-gain test and hypothesis test using the Paired Sample T-Test. The experimental class implements the Inquiry Based Learning model based audio and visual using STEM approach while the control class is nonaudio and visual. The results showed by the average value of N-Gain Intrinsic Cognitive Load (ICL) in the experimental class was 0.63 with the moderate category and the control class was 0.18 with the low category. Based on data analysis, can be concluded that there is a positive influence in the form of a decrease in the cognitive load Intrinsic Cognitive Load (ICL) in the experimental class using the Inquiry Based Learning model plus an audio and visual based STEM approach.

Efektivitas Model Pembelajaran Kooperatif Jigsaw Berbasis STEM (Science, Technology, Engineering, And Mathematic) Terhadap Kemampuan Metakognisi

“…Pendekatan STEM merupakan pembelajaran yang menggunakan pendekatan berbasis saintific dan matematika berdasarkan aktivitas yang berkaitan dengan peningkatan teknologi yang digunakan untuk mempermudah peserta didik untuk terbuka pemikirannya (Anwari et al, 2015). Pendekatan pembelajaran yang berpusat pada peserta didik dapat mengoptimalkan kinerja peserta didik dalam pendekatan STEM (Sundari et al, 2021).…”

Analysis of Student's Rational Thinking Ability in a Career Perspective in the Field of Science, Technology, Engineering, Mathematics (Stem)

“…Based on the description above, students must have the ability to think rationally as a capital in determining their future careers based on their views on STEM (Science, Technology, Engineering, And Mathematics) because STEM itself will provide experience for students. (Sundari et al, 2021) Based on the results of initial observations, the researchers found the uniqueness of the research site, namely by showing the ability to think rationally which includes the ability to classify, imagine and imagine. One of the science teachers at the research site has gradually introduced the STEM approach to learning.…”
