Abstract

The practice activities carried out in the ground area do not fully recognize the environment with the blended learning process. This development research aims to produce E-Student Worksheet (E-SW) teaching materials that can increase students’ naturalistic intelligence on freshwater ecosystem materials for aquatic ecology courses at the Biology Education Study Program, FKIP University of Riau. Development research using the ADDIE model Students measured parameters by validity, practicality, and naturalistic intelligence assessed. Data collection was carried out through field observations, interviews, and the dissemination of questionnaires. The trial subjects consist of 1 material expert, 1 educational expert, and 1 media expert, a small group trial of 15 students and a large group trial of 35 students. The data is analysed by the descriptive method. The results showed that the validity of the Electronic E-SW was very valid with an average value of 95.67% based on the aspect of display quality 94.64%, software aspects 93.75%, usage aspects 95.31%, content and material feasibility aspects 95 .67 %, and linguistic feasibility aspect 95.83%. The practicality of E-SW is relatively practical, with an average value of 78.96% based on the aspect of use 79.08%, the aspect of time efficiency of 77.43%, and in the aspect of benefits of 79.23%. The Naturalistic Intelligence of students using E-SW increased from 64.02 (good) to 83.18 (very good). E-SW is very suitable to be used as teaching material for practicum activities in aquatic ecology lectures. The implications of this research are expected to be an alternative to E-SW teaching materials in the lecture process by blended learning or face-to-face.
