Abstract

This study aimed to determine the effect of applying the flipped classroom model to students’ learning outcomes in oxidation-reduction reactions. It was conducted in SMAN 47 Jakarta. Research method is quasi-experimental with nonequivalent control group design. The sample consisted of 72 students were taken with purposive sampling. Independent variables are the flipped classroom model and direct instructional. Chemistry learning outcome became a dependent variable. The flipped classroom model is invers of the traditional learning model. Students learn the instructional material at home through videos and discussions in class. Analysis of the requirement’s test showed that the data were normally distributed and had homogeneous variances. Hypothesis testing showed different results in a significant level of 0.05. The differences of average value between pretest and posttest of the experimental group is 12.50. While the differences in the control group was 7.17. It can be concluded that the difference of average value between pretest and posttest of the experimental group is higher than the control group. The flipped classroom model can improve students’ learning outcomes in the oxidation-reduction reaction.

Abstract

The development of a chemistry experiment based on green chemistry aims to train and familiarize students to save on the use of chemicals, replace them with safer materials and minimize waste generated from experimental activities. Research and development methods are used to develop experimental modules based on green chemistry. The stages of research and development consist of needs analysis, product development, and product testing. The developed experiment module, implements three principles of green chemistry, i.e. preventing waste, safer chemical planning and safe use of solvents. The feasibility test by expert judgement on the material and media obtained scores 91.9% and 94.7% respectively. The results of the trials in small groups and large groups showed that the developed module was feasible to use. Student perceptions after using the module show positive results. The conclusions from the results of the feasibility test and the trial conducted indicate that the green chemistry-based kinetics' module has good criteria and in accordance with the wishes and needs of students. In addition, the implementation of this module in the kinetics experiment succeeded in making students understand and apply the principles of green chemistry. As many as 90% of students realize that there is a relationship between the application of the principles of green chemistry and the educational paradigm for sustainable development. The use of kinetics' module based on green chemistry also saved the cost of experiment material requirements by 75% per year.

Abstract

This study aimed to analyze the 21st century skills of students in learning chemical equilibrium with the Flipped Classroom-Collaborative Problem Solving model. Flipped Classroom is a learning model that students learn first outside the classroom through video, then carry out active activities in class such as discussions, presentations, making posters, and doing practicum. Collaborative problem solving is done when students discuss in solving problems for each learning activity. The research method used descriptive qualitative method. Data collection techniques were: observation, interviews, questionnaires, and reflective journals. Data analysis consisted of several stages, namely data collection, data reduction, data presentation, and verification or conclusions. Based on data analysis, this learning model made students active in learning and also made the students learn independently outside the classroom using mobile learning and searching some sources of references. In addition, students were actively involved in problem solving discussions, presentations, making projects, and practicums that were designed by students themselves. Thus it can be concluded that the Flipped Classroom-Collaborative Problem Solving learning model can train and grow students critical thinking skills, creativity and innovation skills, communication skills, and collaborative skills in learning chemical equilibrium.

Abstract

This research aims to analyze the effect of the applying of SWH-based experiment method and the achievement motivation of 7th-grade students toward the Science’s learning outcome in the chapter of Properties and Physical and Chemical Changes. The applied of SWH-based experiment method and achievement motivation is an approachment to support the process of learning. The research was conducted in October 2015 until June 2016 at private junior high school in Bekasi. The method of study that used is quasi-experiment with factorial design 2x2. The sample consisted of 40 students which determined by simple random sampling technique. The data of cognitive learning was measured by the learning outcome and learning motivation which determined based on the questionnaire. The gained data were distributed normally and homogeny. The data analysis result was using two-way ANAVA test, resulted: 1) the applied of SWH-based experiment method lead to an increasement of Science’s learning outcome compared to conventional method; 2) the applied of SWH-based experiment method toward student with high achievement motivation lead to a better learning outcome rather than conventional method; 3) the applied of SWH-based experiment method toward student with low achievement motivation didn’t lead to a higher of Science’s learning outcome than the applied of conventional method; 4) an interaction was found between experiment method and motivation of achievement toward the learning outcome.
