Abstract

The innovation of student activity worksheet is one of the alternative ways to complement teaching materials in 2013 curriculum. The learning process will be more meaningful if the student activity worksheet used raises contextual material. The purpose of this study is to analyze the feasibility and practicality of CTL-approched student activity worksheet in environmental change material as one of the teaching materials in the learning process. The research method used in this study is a modified Research and Development (RnD) by Sugiyono (2015). The instruments used in this study are validation sheet by material and media experts, student activity worksheet readability questionnaire sheet by students, practicality questionnaire sheet by teacher & students, and interview guidelines. The validity of the material obtains a score of 82.14% with very Feasible criteria and it shows the suitability of the material presented with the CTL approach. The validity of the media obtains a score of 94.6% with very valid criteria and it shows the suitability of the graphic and language aspects. The results of the readability test by students shows a score of 75.2% with Feasible criteria. The result of the practicality assessment of student activity worksheet by teacher reaches a score of 95.83% with very practical criteria and by students reachs a score of 76.23% with practical criteria. Based on the research results, it can be concluded that the developed-CTL-approched student activity worksheet is very feasible and practical to use in learning process.

Abstract

Technological advancement is one aspect that can be used to support the learning process. Through the use of technology, one of them is by applying blended learning models students get new experiences that will help them in understanding the material. This study aims to examine the effectiveness of blended learning models on the motivation and learning outcomes of Don Bosko High School students on ecological materials. This research is an experimental research using quasi experiment nonequivalent control group design. Population of students in grade X mipa at Don Bosko High School. The samples used were class X MIPA 2 as experimental class and X MIPA 3 as control class. Sampling using puspossive random sampling. The independent variable in this study is the model of blended learning of ecological material, the dependent variables are the motivation of learning and learning outcomes. The results showed that the percentage of students' learning motivation in the experimental class was 96% while in the control class 84.62% were in a very good and good category. Cognitive learning outcomes in the experimental class were higher than the control class with 84% of students achieving the established KKM. Improved learning outcomes in the experimental class showed moderate categories, while in the control class was in the low category. These results were reinforced by a questionnaire of student responses that gave a positive response to the blended learning model. Based on the results of the study, it was concluded that the blended learning model of ecological material is effective against the motivation of learning and student learning outcomes.

Abstract

The background of the problem in this study is the analytical ability of students of SMA Negeri 13 Semarang on biotechnology material is still low. One of the consequences on the absorption of UN in 2017, 2018 and 2019 in the puspendik is also low. The teaching materials used are not yet in accordance with the needs and tastes of learners. in addition, learning is still focused on teachers with lecture and discussion methods. This, resulting in KD biotechnology has not been achieved. This research aims to develop research-based e-booklets on the application of conventional biotechnology as a supplement to biotechnology materials facilitated with learning devices. The research method used is Research and Development. Data collection in this study used interview guidelines, validation assessment sheet, clozure technique form, and response questionnaire. The results showed that based on expert assessment of materials and media on e-booklet developed showed very valid criteria with an average percentage of 92.77% and 93.4%. Trials of learners in the clozure technique got an average percentage of 96.33% with high criteria. Meanwhile, students and teachers' responses to e-booklets get an average percentage of 91.25% and 97.22% with very decent criteria. In the validation assessment, learning devices get very valid criteria on all devices created, including syllabus, RPP, LKPD, and evaluation questions with the average percentage obtained in a row is 87.76%; 90,04%; 92,01%; and 93.17%. Through learning using e-booklets that have been developed and refer to learning tools that have been created is expected to improve the analytical skills of learners.
