Abstract

The research on the development of this textbook was carried out based on the results of the analysis of student needs, namely that there are no teaching materials that can improve students' science process skills in the Tissue Culture course at the Department of Biology, State University of Medan. This textbook is compiled based on the learning syntax of Project-Based Learning (PjBL). This study aims to develop a Project-Based Learning-based tissue culture textbook to improve students' science process skills. This research method uses the Research and Development (R&D) with Thiagarajan's 4D (Define, Design, Develop, and Disseminate). The population of this study was students of the Biology Department of Universitas Negeri Medan with a sample of 47 people who were given a PjBL-based tissue culture textbook. The results showed that (1) the textbooks have been tested for feasibility by material experts (87,73) (2) instructional design experts (92) with a very feasible category, (3) the response of tissue culture lecturers (92) and (4) students based on individual tests (95.1), small group tests (93,75), and limited group tests (90.02) with a very good category and (5) the results of the calculation of N-Gain for science process skills were obtained at 0.66 which is in the medium category.

Abstract

This research aims to develop and test the feasibility and effectiveness of the module of human excretory system based on Problem Based Learning (PBL). The research method use is Research and Development (R&D) with the 4-D model, namely the defining stage, the design stage, the development stage, and the dissemination stage. Validation was conducted by module design experts with an average score of 93.32, material experts 92.32, learning experts 90.86, and one biology teacher of class XI 94.68, all categorized as “very feasible.” The module appeal trial shows high results with assessment categories 85.01 - 100 (highly appealing), 70.01 - 85 (appealing), 50.01-70 (less appealing), and 01.00-50 (not appealing). The results of the individual trial were 3 students at 100 (highly appealing), a small group of 10 students at 82.14 (appealing), and a limited group of 20 students at 98.75 (highly appealing). The effectiveness of the module tested through student learning outcomes using independent t test. In the cognitive aspect, the average value of the experimental class reached 96.15 (very good) with t count 2.170 > t table 1.666 and supported by a significant value of 0.033 <0.05. Affective aspects obtained a value of 94.30 (very good) with t count 2.296 > t table 1.666 supported by a significant value of 0.025 < 0.05, and psychomotor aspects reached 97.13 (very good) with t count 7.619 > t table 1.666 supported by a significant value of 0.000 < 0.05. The results of this study indicate that the developed module can be useful as an effective alternative learning media to improve students' learning outcomes.
