Abstract

Education today focuses on creating characters who are able to face future challenges. The first challenge in this global era is the need for every student to have process skills in 21st century learning known as 4C: (1) Communication Skills, (2) Collaboration skills, (3) Critical Thinking and (4) Creative. One of the characteristics desired in 21st century education is a communicative and collaborative character. The purpose of this study was to determine the improvement of the communicative and collaborative character of students after using guided inquiry-based e-LKPD on acid-base material. The form of this research was quasi-experimental research. The research sample consisted of 2 classes, namely the experimental class (XI MIA 1) and the control class (XI MIA 2). Based on the research, the results showed that the use of guided inquiry-based e-LKPD on acid-base material can improve the communicative and collaborative character of students through observation results with an average value in the experimental class, respectively, namely 89.25% and 85% with the high category compared the control class is 44.75% and 36.75% with the low category.

Abstract

The research on the development of e-modules on hydrocarbon compound material for agricultural vocational school education units aims to develop e-modules that are in accordance with the demands of the agricultural vocational curriculum. This study used a research and development (R&D) method with the ADDIE development model which only consists of 3 stages, namely analysis, design and development. The object of research was the e-module on the material of hydrocarbon compounds. The research subjects were 3 educators who taught chemistry subjects at the Agricultural Vocational School and 23 Agricultural Vocational Schools students. Data collection was done through validation sheets and response questionnaires. The results showed that the e-module developed was very valid or very feasible to be tested in the field with an overall average percentage value of material validation of 91.69% and an overall average percentage of media validation of 94.13%. Based on the results of the test, the response of educators obtained an average percentage of 85.18% with the very good category and the results of the students' responses obtained an average percentage of 72.72% with the attractive category. Thus it can be concluded that the e-module of hydrocarbon compounds is very good and interesting to be applied in the learning process on a larger scale.

Abstract

Molecular shapes and intermolecular interactions materials were quite difficult because it was related to abstract concept that must be presented with multiple representations, so it was necessary to procure PBL-MR (Problem Based Learning-Multiple Representation)-based teaching materials to present this concept in concrete way. This study aimed to develop student e-worksheet based on PBL-MR in molecular shape and intermolecular interactions materials using flip builder application. The method used is Research and Development (R & D), with the Plomp model. This method consisted of three phases, namely (a) preliminary research phase, (b) development phase and (c) assessment phase. Evaluation of the validation was carried out by 3 media experts and 3 material experts. 1-1 test which was assessed by 3 students from the SAF school in Pekanbaru. Small scale with users response to assess practicality by 3 teachers and 30 students from 3 schools, namely MP1, SP2 and SAF in Pekanbaru. The results showed that student e-worksheet was rated very valid with average percentages of material experts 93.83% and media experts 100%; test 1-1 got comments from students and improvement of questions in student e-worksheet; teacher and student responses got average percentages of 95.83% and 84.23% with very practical category. In conclusion, the student e-worksheet was very valid and very practical, so it was suitable for use in chemistry learning.AbstrakMateri bentuk molekul dan interaksi antar molekul tergolong sulit karena terkait dengan konsep abstrak yang harus disajikan dengan multi representasi, sehingga perlu dilakukan pengadaan bahan ajar berbasis PBL-MR (Problem Based Learning-Multiple Representation) untuk menyajikan konsep ini secara konkret.
