Does learning chemistry by representation with “Jaman-Now App_Permilang” effectively impact students’ cognitive & motivation?

Abstract

Technology has become a major component in every aspect of human life, and learning resources had included in that aspect. This issue described media for learning the "Jaman-Now App Permilang (JNAP)" can have an effect on students' cognitive and their motivation in the learning process. The quantitative approach was the method used in this study, where this research was a part of the development research conducted by researchers, in which this research presentation specifically explained aspects of the effectiveness of the product being developed. Product feasibility tests are carried out in the school environment through two processes (limited & extensive test). Those processes were used with observation, testing, and questionnaire techniques as a measure of product success. The feasibility of this research focused on the effectiveness of the product in chemical learning where this effectiveness is assessed as an indicator of product feasibility with a valid instrument (cognitive tests, questionnaire). Statistical data revealed that the average N-Gain in the 1st process has a point of 0.25 (low), the 2nd process was 0.42 (medium), and very good criteria for the motivation aspect. The results indicated that the product has a good enough impact on the co-positivity and motivation of students, although the visualization of the values shown in the medium criteria. In other words, the product has the potential to become one of the strategies in improving the quality of chemical learning, assessment for chemistry learning, strengthening their cognitive, and guidelines for students in reflecting themselves in an understanding of the chemical material.
