The development of Musi estuary ecosystem alternative teaching materials as supplementary books for biology learning in high schools

Abstract

Student textbooks were generally limited with examples and were also seldom found relevant to students’ daily lives which often caused biology learning not to run contextually. Meanwhile, there were many contexts around students that could be used as references or learning resources. One of the local potentials found on the east coast of South Sumatra was Musi estuary. There were many potentials such as the wealth of biotic components and their abiotic factors. Therefore, we needed teaching materials that could complete the use of textbooks in schools, this aimed to help students more easily understand concepts through relevant contexts. The development of teaching materials used the ADDIE approach; analysing, designing, developing, implementing and evaluating. Making alternative teaching materials for Musi estuary ecosystem had arrived at the development stage followed by evaluating each of the previous stages. This research was using the validation questionnaire of the National Education Standards Agency (BSNP) including aspects of the feasibility of content, the feasibility of language, the feasibility of presentation and the feasibility of graphics. The teaching material has validated by 3 experts and 3 high school Biology teachers. Based on the results of material validation by experts it was obtained an average score of 3.13 (77.38%), and high school biology teacher 3.33 (83.17%), which then concluded that the alternative teaching material of Musi estuary ecosystem was discovered eligible to be used as a supplementary of biology textbooks on grade X for ecosystem learning material.
