Abstract
Rotational dynamics is one of topic in physics for high school students that require visualization of its concepts. This research developed an interactive e-book for physics learning with its features consisting of multimedia content such as audio, video, animation, and simple problem-solving activities. This e-book has been validated and recommended by a team of experts. This trial aims to determine the effectiveness of e-book by students in mastering concepts, using a. quasi-experiment. The sample was chosen using purposive sampling technique at senior high school with 42 students. Data were collected using multiple choice questions. The increase of student concept mastery is determined based on the N-gain score of pretest and posttest data. The results show that the average student response to e-book is 81% in the very good criterion. The N-gain scores for the equilibrium concepts of A and B classes are 0.79 and 0.70 in the high criteria, while, the concept of rotational dynamics are 0.66 and 0.66 respectively and in the medium criterion. The increase of conceptual mastery occurs in every cognitive domain (remembering, understanding, applying, analyzing, evaluating, and creating). In conclusion, the e-book has been effective in enhancing the mastery of student concepts.
Highlights
The e-book is a digital version of the traditional printed book read on a personal or desktop computers, laptops, smartphones, tablets, or e-book readers [1]
Each group is given a pre-test through 24 items of multiple choice questions which consists of 12 items on the concept of 'Equilibrium of rigid bodies,' and the ‘Rotational Dynamics.’
The results show that the interactive e-book design is 'Feasible' to be used as teaching material in physics learning
Summary
The e-book is a digital version of the traditional printed book read on a personal or desktop computers, laptops, smartphones, tablets, or e-book readers [1]. The Indonesian government, through the Ministry of Education and Culture, has provided e-books for schools which are accessible online in PDF format (Portable Display Format). E-book PDFs are designed like a printed book and cause significant eye effect [2], such as dry eyes, ocular discomfort, headache, and other visual symptoms [3]. Users tend to read quickly to obtain main points. This is not optimally utilized because limited learning message is acquired, and the concept is not fully conveyed. E-books have been designed with more interactive features such as audio, video, slideshows, and image galleries [4]. There are variables in the interactive e-book diagrams, symbols, signs, shapes, and tools which supports thinking skills [6]
