THE EFFECTIVENESS OF E-BOOK DEVELOPMENT ON MOSSES IN IMPROVING STUDENT LEARNING OUTCOMES

Abstract

Plantae material consists of three main materials, namely mosses, ferns and seed plants. The material on mosses is difficult for students to understand because 1) the small size of mosses 2) the structure, properties and characteristics are difficult to distinguish so that the phenetic and phylogenetic classifications are difficult to determine and 3) the stages of metagenesis are complicated due to their invisible size. Moss material needs to be packaged in e-book form to make it more interesting. E-book development needs to take advantage of the environment, so that students can easily remember facts, concepts, and relate theory. This study aims to analyze the effectiveness of the developed e-book in improving student learning outcomes. the research method used Quasi Experiment with nonequivalent control group design. Population of X IPA class at SMA N 12 Bandar Lampung with X IPA 1 experimental class and X IPA 2 control class. Data collection was carried out using test, lift and interview methods. The results showed that the learning outcomes of the experimental class were higher than the control class. The results of the N-gain calculation in the experimental class were 0.72 with high criteria and ≥80% of students achieving a value of ≥75%. Based on the results of the study, it can be concluded that the e-book material on moss plants that was developed was effective in improving student learning outcomes.
