Design and Application of Augmented Reality in Science Education to Develop Students’ Critical Thinking Skills

/in /by

The goal of this project is to create instructional materials based on augmented reality (AR) that will enhance students’ critical thinking abilities. There were 25 pupils enrolled in the public junior high school where the study was done. The ADDIE approach is being used in this development research study. The resulting product is AR-based media equipped with learning devices consisting of a Learning Implementation Plan, Student Worksheets, test instruments. Data collection was carried out using validation sheets, learning implementation sheets, student activity sheets, critical thinking tests and student response questionnaires. The percentage of each score attained was calculated in order to analyse the data. The findings indicated that the student worksheet’s validity scored 85.3 in the very valid category, the learning implementation plan’s validity scored 87.3 in the same area, and the learning outcome test’s average validity score was 90 very valid. With an average of 93.6%, learning implementation indicated very good outcomes; student activities in learning showed very good results with an average of 94.3%; and 88% of student responses fell into the very good category. The critical thinking test’s findings indicated that the critical thinking indicators of interpretation, analysis, and explanation had the biggest increases, and the conclusion indicator saw the lowest. The study’s conclusion is that teachers can use the augmented reality-based learning tool to teach the Life Organization System’s content since it is valid, practical, and effective.

Framework of Problem-Based Learning Activities with STEM Approach: Utilizing Plastic Waste with Ecobrick Method in Improving Students’ Ecological Literacy to Solve Environmental Problems

/in /by

Plastic is a difficult chemical to degrade or decompose naturally, taking hundreds or even thousands of years for nature to break down plastic. However, the reality is that plastic is widely used in various human needs, from food packaging materials to automotive materials. One way to overcome plastic waste is through eco-brick or utilizing waste with plastic bottle media. Ecobrick is one creative effort to manage plastic waste into useful objects and reduce pollution and toxins caused by plastic waste. Teaching about eco-brick issues can be used as teaching material to improve students’ ecological literacy. Ecological literacy is a state in which individuals have good knowledge and attitudes about the environment and are capable of taking actions that positively impact the environment. However, the ecological literacy of students could be a lot higher. One of the reasons for this is that the teaching methods used so far have yet to bring out their ecological capabilities. Therefore, this study will apply problem-based learning (PBL) with a STEM approach. PBL is a learning approach involving a specific syntax combining STEM disciplines of Science, Technology, Engineering, and Mathematics. This approach can improve students’ ecological literacy in solving environmental problems.
