Abstract

The validity and practicality of the media are a condition before it can be widely piloted. This research aims to find out the validity and practicality of the Evolution Virtual Laboratory Learning Media, which was developed based on the artefacts of the Sangiran Site to empower science literacy of students. The media validity test using expert judgment involved two expert validators, and two high school biology teachers. While the media practicality test involved 20 grade 12th students. The instrument used was a validity questionnaire consisting of 9 items (material experts), 18 items (media experts), and 13 items (practitioners). Questionnaire instruments to students as many as 16 items. All questionnaires use the Likert Scale. The test results showed material experts rated 86.80%, media experts 84.6%, education practitioners 84.30%, and students by 79.00%. Based on the validity and practicality of the Sangiran Site-based Evolution virtual laboratory learning media is declared valid and practical, so it can be used for effectiveness testing.

Abstract

Critical thinking skills greatly support students to think analytically, thus making themselves intelligent. Two factors influence students' critical thinking skills, including the first from teacher resources. This study aims to determine empirical data related to the effectiveness of using the Discovery Learning Model for students. The method used is meta-analysis, namely a statistical review by analyzing the results of research published internationally related to the use of the Discovery Learning model on critical thinking skills. The analysis sample consists of 4 international journals published in 2017 - 2022 at the high school level, which discuss the writing of experiments on the effectiveness of using the Discovery Learning model on critical thinking skills. The writing instrument is in the form of a coding sheet that summarizes journal data and information. Based on the analysis of the overall influence value, the average value of the effectiveness effect is ≥ 0.8, which means it is in the large effect category. The findings of the analysis also show that the effectiveness of using the Discovery learning model affects increasing critical thinking skills compared to conventional methods. This provides the conclusion that the use of the Discovery Learning model on critical thinking skills is effective in learning.
