Development of digital learning media based on android games with joyful inquiry model to increase science literacy skills for second year students of junior high school in subject matter of vibration

Abstract

The aim of this research was to develop digital learning media in the form of android games to improve students’ scientific literacy skills. Digital learning media are developed based on the joyful inquiry learning model for the subject matter of vibration. The validation of digital learning media was carried out by media experts, subject matter experts, science teachers, and second year students of Junior High School 1 Duduksampeyan in Gresik Regency, Indonesia. The results of expert validation showed that digital learning media is very valid with a validity rate of 84% and readability rate of 87%. The effectiveness of digital learning media in increasing students’ scientific literacy was measured by quasi experiments using two classes of second year students of Junior High School 1 Duduksampeyan in Gresik Regency, Indonesia. The class VIII-F used digital learning media with the joyful inquiry learning model and the class VIII-E used the inquiry learning model. The results of the independent sample t-test showed a significance value of 0.0012 (smaller than α = 0.05) which meant that there were significant differences between the scientific literacy abilities of the class VIII- F and the class VIII-E. The N-gain value of the class VIII-F is 0.72 and this value is greater than the N-gain value of the class VIII-E that is 0.47. These results indicate an increase in the scientific literacy ability of students in the class VIII-F is higher than that of class VIII-E students which means that the digital learning media developed are effective in increasing students’ literacy abilities.
