Abstract

Learning media is a tool used in the school that can help teacher in the teaching process. Media that is made according to needs can help students achieve learning goals effectively and efficiently. This research aims to determine the feasibility of booklet the role of biodiversity based on inventory of post-birth medicinal plants in Mekar Sari Village on the sub-material role of living things for life in class X. This study uses research development by Sugiyono which consists of determining potential and problems, data collection, designing media, validating, finally revising the design. The validity of the booklet media was obtained through content validation carried out by five validators. Booklet media validation is viewed from three aspects, namely format, content and language. Validation analysis refers to Lawshe (1975), namely content validity ratio (CVR) and content validity index (CVI). The research results show an average CVR of 1.00 and resulting in a CVI of 1.00 in the valid category. The results of the analysis in this research can be concluded that booklet media is suitable for use as learning media

Abstract

The development of information and communication technology has a significant impact on the world of education, particularly in the provision of learning media. Video-based learning media has become an effective alternative for visualizing complex materials, such as in the bioassay technique course. This study aims to develop and assess the feasibility of educational videos as media for the Bioassay technique course, which includes material on testing using animal testing. This study uses the research and development (RD) method with a modified ADDIE development model consisting of four stages: analysis, design, development, and evaluation. Data collection techniques include validation by experts. The instrument used is a validation sheet with a Likert scale. The aspects assessed include format, content, and language. For the four indicators in the format aspect, a validity score of 1 was obtained. Similarly, for the three indicators in the content aspect, the validity score was also 1, and for the two indicators in the language aspect, the validity score remained at 1. Overall, from these three aspects, an average validation score of 1.00 was achieved, categorized as very high. Therefore, the video is deemed suitable to be used as a learning media in the bioassay technique course.

Abstract

Learning media is one component in the learning system which functions as a means of non-verbal communication. The use of learning media aims to help educators convey information so that it is easy to understand, learning becomes effective and efficient, increasing student activity and student motivation to learn. Media creation can also be developed based on the research results. The aim of this research is to determine the feasibility of a sub-material encyclopedia on the role of the biodiversity for life in class X based on the results of inventory of medicinal plants for male and female reproductive health in Balai Harapan Village, Tempunak District, Sintang Regency as a learning medium. This research uses development research methods. This development procedure consists of determining potential and problems, gathering information, designing the product, validating the design, and revising the design. The validity of the encyclopedia is obtained through content validation carried out by five validators. Encyclopedia validation is viewed from three aspects, namely presentation, content and language. Validation analysis uses Lawshe's (1975) content validity ratio (CVR) and content validity index (CVI) approaches. The research results show an average CVR of 1.00, resulting in a CVI value of 1.00 in the "valid" category. Based on the research results, it can be concluded that the encyclopedia is suitable for use as a learning media

Abstract

In study of biology, explore the concepts rather than just memorise them is important. That's why use of media can make learning process more attractive and easy to understand for students. This study aimed to determine the feasibility of using breastfeeding and family planning sub-material pocket book media based on an inventory of breastfeeding-promoting plants in Pasti Jaya Village, Bengkayang Regency, West Kalimantan Province. The research and development process included identifying potential benefits and problems of media as a support for learning, gathering information on the plants, designing the product, and assessing the pocketbook with five validators. The pocket book was evaluated based on its presentation, content, and language, and the results showed that it's suitable for use as a learning tool. The validation results were then analyzed by Lawse calculations. The results showed that of the three aspects with twelve criteria, the validation content validity ratio value was 1.00 with a valid category. The average of all content validity index criteria obtained a value of 1.00 with a valid category, which shows that the breastfeeding and family planning sub-material pocketbooks are suitable for use as learning media
