Development of HOTS Integrated Problem Based Learning (PBL) Chemistry Learning Module on Buffer Solution Material at SMA Negeri 1 Purba

Abstract

This research was conducted to design a Problem Based Learning (PBL) based learning module with the ADDIE model. The problems studied are 1) How is the feasibility (validity) and learning effectiveness of the Problem Based Learning (PBL)-based module developed on the buffer solution material to measure students' Higher Order Thinking Skills (HOTS) and 2) What are the students' chemistry learning outcomes using the module-based Problem Based Learning (PBL) is higher than the KKM score. The subjects of this study were 3 expert validators (expert lecturers), and 1 high school chemistry teacher to evaluate the learning to be developed and class XI MIA students of SMA Negeri 1 Purba who were determined by random sampling using an experimental class totaling 30 students. The results of the study showed that 1) the problem-based learning module for chemistry-based learning buffer solution material that was developed was feasible to be used for learning materials to improve students' critical thinking skills. The module is declared effective as seen from the increase in student learning outcomes, namely the average pretest value of 33.5 and posttest 80.13 in the experimental class, 2) The learning outcomes of chemistry using Problem Based Learning (PBL)-based modules developed on buffer solution material are higher than the value KKM (75) with an average score of 80.13.

Development E-Assessment Literacy Oriented Higher Order Thinking Skills (HOTS) on Thematic Learning to Measure Critical Thinking Skills of Primary School Students

“…Evaluation stage, carried out on development products in the form of content/materials developed by learning media and evaluating the effectiveness and success of the media developed (Panggabean et al, 2022). Field trials were carried out in class V at SDN Berundung.…”

Development of an inquiry-based virtual laboratory to facilitate biology practicum for high school students

“…These criteria include holding a doctorate degree in biology, biological education, education, educational technology, or education technological and vocational, as well as having prior experience as a validator of educational products (Septiani, 2020). Meanwhile, participants in the product trial stage consisted of practitioners, in this case biology subject teachers at high school, a total of 5 teachers who were involved in the product trial assessment process (Panggabean et al, 2022). Before validation activities were carried out by experts to see the level of product feasibility, virtual laboratory media was developed using the Adobe Animate application, and the design process was created using Corel Draw and Adobe Illustrator.…”
