Abstract

This study is a development research that aims to produce STEAM-based electronic learning device on colloid material to increase student’s interest and learning achievement that are valid, practical and effective. The development model uses the ADDIE development model which consists of 5 stages : (1) the analysis phase includes curriculum analysis, student analysis, concept analysis, formulation of learning objectives, and task analysis; (2) the design, which includes the stage of selecting the format and initial design of the RPP, e-module and E-LKPD using the Canva application; (3) the device development stage by integrating STEAM aspects and following the Project Based Learning (PjBL) syntax; (4)the deployment stage is the testing phase of learning tools that have been validated by experts and have been revised by developers; (5) the evaluation phase includes the evaluation of learning devices after going through the trial phase. Analysis of the results of the validation of RPP, e-Modul and e-LKPD based on the STEAM PjBL model, namely 3.53; 3.80; and 3.77 very valid categories. Practical based on the practicality test by looking at the implementation of STEAM-based learning the PjBL model has an average value of M = 1.87 which means that it is fully implemented; the responses of students and teachers were very positive with a percentage of 90.91% and 85.25%. Learning Devices also meet the effective criteria because the class completeness reaches 84.85% and the n-gain results in increasing interest in learning are in the medium criteria.

Abstract

This experimental research aims to examine the influence of Discovery Learning Model on critical thinking skills and redox learning outcomes. The research design used was Posttest-Only Control Design and obtained students of grade X MIA 1 cconsisted of 25 people as the experimental class and grade X MIA 2 consisted of 29 people as the control class. The data analysis techniques used were descriptive and inferential statistical analysis. The results of the study reveal that learning using the Discovery Learning Model obtains the value of critical thinking skills are 79%. The cognitive learning outcomes are 83%, affective learning outcomes are 83%, and psychomotor learning outcomes are 80%, which is higher than conventional learning. Thus, they have a significant influence based on hypothesis testing on learning outcomes and critical thinking skills with the value of Sig. (2- tailed) < 0.05. In addition, the results of critical thinking skills have a correlation with learning outcomes with Pearson correlation values of 0.853, 0.811, and 0.652, outcomes is at a very high and sufficient level of closeness. Therefore, the conclusion of the study is the use of Discovery Learning Model influences critical thinking skills and redox learning outcomes.

Abstract

This development research aims to develop an application-based learning media called the Edmodo application by adopting the Flipped Classroom learning model into learning to increase students' motivation and learning outcomes during the pandemic in Reaction Rate subject which is valid, practical, and effective. The development model used in this study referred to the Addie development model, which consisted of several stages, namely analysis, design, development, implementation, and evaluation. The Edmodo media developed had conducted through the validation stage by validators/experts and had gone through trials, and had been revised by developers so resulted a learning media which is valid, practical, and effective. The results show that the developed Edmodo media has: (1) the media expert validation by 3.96 with very valid criteria, (2) the material expert validation by 3.83 with very valid criteria. Edmodo media is stated to be practical because in the practicality test related to: (1) its implementation in the Flipped Classroom learning model is at an average value of M = 1.98 with the category of fully implemented, (2) the teacher's response is very positive with a percentage of 97.00% with very practical criteria, and (3) the students' responses are very positive with a percentage of 83.69% with very practical criteria. The media also met the effectiveness criteria with the results: (1) there is a difference in the average students’ learning motivation before and after the trial and (2) the learning outcomes meet the effective criteria with a class completeness percentage of 84%.
