Improving ISLE-based STEM learning outcomes for building the 21st century skills and characters through a lesson study: A case study on Torque and Moment of Inertia

Abstract

The objectives of this study are as follows: (1) Developing ISLE-based STEM learning media, (2) Building 21st-century skills and character, (3) Analyzing the improvement of learning outcomes through lesson study. This research is a descriptive quantitative study developed at the STEM UNSYIAH Research Center and carried out at Unsyiah Laboratory High School. The instruments used in this study are validation rubric for media and material experts and Teacher Observation sheets and monitoring sheets for the increasing 21st-century character. Based on the data analysis: 1) Validation of the Moment of Inertia props from 2 media experts obtained an average percentage value of 86.4% with an excellent category. 2) Validation of Student Worksheet by two validators expert in material teaching obtained an average percentage value of 84.77% with an excellent category. 3) The teaching and learning results using teaching aids and LKPD through a Lesson Study conducted by the observer obtained a percentage with an average of 83.5% excellent category. 4) There is an increase in 21st-century character in students by 77% with an excellent category. ISLE-based STEM Learning Media is very suitable for improving 21st-century skills.

“…This is supported by the average value of the pretest-posttest which has increased by 0.75 with high criteria. In accordance with the research results of Ulfa, et al (2021) that ISLE-based learning is very suitable for improving 21st century skills including students' creative thinking skills.…”

“…The investigations conducted in the ISLE approach are more about building knowledge . Research on the development of ISLE-based learning devices has also been conducted by Ulfa, et al (2021) who found that ISLE-based learning devices can improve students' critical thinking skills, as well as critical thinking skills with interconnected creative skills in producing an effective thinking to solve a problem (Mayarni &Yulianti, 2020).…”

Analysis of learning styles in terms of knowledge, skills and attitudes

“…Besides using learning styles, improving learning outcomes can also be done with several methods, media or other learning models, including using problem-solving learning models (Alqurashi, 2019), interactive-invention teaching strategies (Ukoh, 2022), and generative learning models with virtual lab. (Li et al, 2019), the Inquiry learning method (Razali et al, 2020), the community science technology approach (Mulyanti et al, 2021), including discovery learning-based SWS (Junina et al, 2020), ELSE-based STEM training (Ulfa et al, 2021), virtual Lab-based SWS. PhET simulation (Halim et al, 2021), and the NHT model (Rahayu & Cahyadi, 2019).…”

Use of the Lesson Study Professional Development Program by Both Stem and Non-Stem Teachers in the Educational Process

“…The varied teaching philosophies and techniques within non-STEM subjects further complicate the integration of Lesson Study. Recognizing and addressing these differences is vital to making Lesson Study a relevant and valuable professional development tool for non-STEM educators (Ulfa et al, 2021).…”
