Abstract

Abstract: The objective of this research was to develop the student worksheet on the subject of chemical bonds. The type of this research was reserach and development (R & D) with the ADDIE development models which include analysis, design, development, implementation and evaluation. This research was carried out to the implementation stage, namely one-on-one trials and limited trials. The study was conducted at the University of Riau FKIP. The object of research is (Connecting, Organizing, Reflecting dan Extending) CORE-based student worksheet. The data analysis technique used in the study is descriptive statistical analysis, which is by calculating the percentage of validation values. The average score of the assessment of the five aspects of student worksheet eligibility by the validator team, namely the feasibility of the content, characteristics of the CORE model, linguistic, presentation, and graphic values were 91.67%, 93.75%, 90.00%, 91.67% and 85.41%, respectively. so, the overall average score of the chemical bond student worksheet validation based on the CORE model is in the valid eligibility category, meaning that the developed student worksheet is feasible to use. While the percentage of teacher and student responses to student worksheet was 92.85% and 91.90% which were on positive criteria.   Key Words: Student Worksheet (SWs), CORE models, and Chemical Bonds.

Abstract

The purpose of this study is to develop PQ4R-based LKPD in high school chemistry learning subject to valid chemical bonds based on aspects of content eligibility, PQ4R characteristics, linguistic, presentation and graphic as well as knowing user responses to LKPD. This type of research is development research with the development process referring to the development of the Plomp model. Consists of the initial investigation, design, realization / construction, test, evaluation and revision, and implementation phases. However, this research is limited only to the test, evaluation and revision phases because the purpose of this study is to develop the product and determine the user's response. The object of this research is PQ4R-based LKPD. Data collection instruments are validation sheets and user responses. The results of the data analysis obtained validity on the aspects of content eligibility, PQ4R characteristics, linguistic, presentation and graphic characteristics, respectively; 97.62%, 95.24%, 91.67%, 95.24%, and 91.67% with valid categories. Trial of user responses by teachers and students in a row; 95.83% and 91.63%, so the LKPD that has been developed is suitable for use in the learning process.
