Abstract

Voltaic cell practical work using synthetic chemicals can produce waste that damages the environment, so environmentally friendly substitute materials are needed.  Green Chemistry based practical work was not available yet at State Senior High School 1 Rambah, Rokan Hulu.  This research aimed at knowing validity and practicality levels of Green Chemistry based practical work on Voltaic Cell topic designed.  It was Research and Development with DDR model consisting of 3 steps–planning, designing and developing.  This research was conducted to the twelfth-grade students of MIPA at State Senior High School 1 Rambah, Rokan Hulu.  Based on research findings, Green Chemistry based practical work on Voltaic Cell topic designed showed that the validity percentages by material and media experts continuously were 96.66% and 94.12% with very appropriate criteria (valid). The practicality percentages of Chemistry subject teacher and student respond continuously were 88% and 92,9% with very practical criteria. Based on the data, it could be concluded that Green Chemistry based practical work designed was very appropriate and very practical to be used as a teaching material in supporting the implementation the practical work on Voltaic Cell topic.

Abstract

This research was instigated with the lack of student involvement in the learning process because the conventional learning model use, monotonous teaching material, and the lack of training on the use of student creative thinking ability. This research aimed at developing creative thinking ability-based student electronic worksheet on Colloid lesson by using ADDIE development model and finding out validity level, practicality, and student response to the student electronic worksheet. It was Research and Development (R&D) with ADDIE development model consisting of 5 steps—analysis, design, development, implementation, and evaluation. But, in this research, only limited to the development step. Practicality test and student response was conducted to a Chemistry subject teacher and ten the eleventh-grade students of Natural Science B at State Islamic Senior High School 2 Kepulauan Meranti. The data obtained were analyzed by using quantitative and qualitative descriptive analysis techniques. Creative thinking ability-based student electronic worksheet on Colloid lesson was tested valid with the percentage 80% by media experts, it was very valid with the percentage 95.45% by material experts, practicality test score by teacher was 85.92% with very practical criterion, and student response percentage was 64.5% with practical category. However, it is hoped that an effectiveness test will be carried out to find out the media effectiveness in the future.

Abstract

This research was instigated with the low of student chemistry learning motivation.  It aimed at finding out whether there was a difference of chemistry learning motivation between students taught by using Science Technology Society learning model and those who were not taught by using Science Technology Society learning model.  It was quantitative research with quasi-experiment method.  The samples of this research were the eleventh-grade students of MIA 2 and 4, and they were 72 students.  Questionnaire and documentation were used to collect data.  Independent sample t-test was the technique of analyzing data.  Based on data analysis results, there was a difference of chemistry learning motivation between students taught by using Science Technology Society learning model and those who were taught by using conventional learning model on Colloid lesson at State Islamic Senior High School 3 Pekanbaru.  It was proven with the score of tobserved higher than ttable at 5% significant level (4.587>1.994).  Based on the result of effect size test by using Cohen’s formula, the score of d 2.59 was lower than 1, and it meant that Science Technology Society learning model affected student chemistry learning motivation significantly.
