Abstract

This research is motivated by the understanding that the current reality shows that the approach that has been developing so far is more naturalistic-positivistic which refers to cognitive coherence. Whereas the cognitive aspect in the context of mastering the subject matter is not the ultimate goal of a learning process. Mastery of subject matter is not the end of the teaching process, but only as an intermediate goal for the formation of better behavior. This study aims to measure the affective competence of students in learning using a value-based approach with the aid of multimedia. Aspects that are measured are acceptance, response, value inculcation, organization of values ​​and characteristics. The research was conducted using a qualitative approach. Data collection is done by using a questionnaire technique. Respondents are students who teach General Biology courses. Learning is carried out using powerpoint-based interactive media while the implementation of value-based learning is inserted in learning activities and the content of teaching materials used. The results showed that the learning process in addition to increasing students' interest and motivation also made students show positive attitudes in terms of: 1) Receiving; 2) Response (responding); 3) Value investment (valuing); 4) Organization of values ​​(organization); 5) Characteristics of life (characterization).

Abstract

Abstract Teachers in Sumber Marga Telang are still faced with difficulties in choosing platforms, developing appropriate media in making teaching materials, and developing evaluation tools according to the needs of their students. This community service activity is carried out to broaden horizons and improve teachers' abilities in developing innovative digital-based learning media by utilizing the Sway and Liveworksheet applications. The platform was chosen with the consideration that it is easy to access, has a simple and easy-to-understand display, has features that are able to accommodate the needs of educators and has free options. The training activity begins with a pretest to see the initial knowledge of the trainees. Furthermore, observations were made in the form of questions and answers with the participants which were then followed by the delivery of material about the theory of media development by the speakers. Furthermore, participants did hands-on practice with the facilitator from the community service team to develop sway and liveworksheet-based media. The results of the Pre Test showed that the average participants' initial knowledge was 52, then there was an increase in knowledge in both theoretical and practical aspects to 76.3 after the training was given.
