Abstract

Critical thinking skills are needed in chemistry learning, because some chemistry is contextual and in Indonesia is still relatively low. This study aims to stimulate students critical thinking skills on the topic of voltaic cells by developing the Selvo E-module apparatus. Research and development is carried out by adapting and modifying the development model through the preliminary study phase and development with limited trials. The sample in this study were students of class XI MIPA Academic Year 2018/2019. The instruments used were valid and reliable essay test questions and questionnaire sheets. Based on the findings obtained, it can be seen that the application of the Selvo E-module can stimulate students to think critically. It is seen from the average value of students pretest at 20.14 and the average posttest value of students is 85.07.

Abstract

Based on the 2013 Curriculum (K-13), the ability to think at a higher level is an ability that must be possessed by every teacher, especially chemistry teachers. This study aims to determine the ability of teachers in compiling indicators of achievement of learning outcomes that require high order thinking skills. This research was conducted on Chemistry teachers who took part in professional education activities of teachers in positions ranging from batch 1 to 4, in 2019. There were 40 teachers who were subject of research in Chemistry. The results obtained are based on the results of testing about 2% of teachers who have been able to compile indicators of learning outcomes based on semi-high thinking (C3). Teachers after attending training above 97% are able to compile indicators of learning outcomes based on higher order thinking (C4). The increase in n-gains increases with a high category

Abstract

The purpose of this research to determine the feasibility of student worksheet base on CORE(connecting, organizing, reflecting and extending) based on the validation data with the data sourcechemistry teacher and student responses to the data source. The design used was a model Researchand Development (R & D), where there is a stage and potential problems, data collection, design,study, revision, validation, and test student worksheet base on CORE. The results of the study designwas tested in the validation and limited so that it will produce a student worksheet base on CORE inaccordance with the standards of eligibility based on the feasibility of the content or materials,presentation and language. Student worksheet base on CORE that was developed has been validatedby two chemistry lectures and three teachers of chemistry and tested on 34 MAN 1 Kota Malangstudents. Achievement of the feasibility of the student worksheet base on CORE is the percentage ofthe overall aspects of the chemistry teacher assessment to validate that is equal to 98.15%, while thepercentage of student responses obtained at 98.52%.

Abstract

One effort to improve student learning outcomes is to choose teaching media that are appropriate and attract students' attention. The media developed is a three-dimensional ball teaching media.The purpose of this study is to develop three-dimensional atomic ball teaching media, to find out the validity level of three-dimensional atomic ball teaching media, to find out the practicalities of the three-dimensional atomic ball teaching media that have been developed. This research is a type of Research and Development (R & D) research using a 4D development model, namely define, design, develop, and dessiminatebut is limited to the develop stage. The teaching media developed were validated by media experts and material experts. The subject of this research trial was a chemistry teacher to find out the practicality of three-dimensional atomic balls teaching media, and 20 students of East Siantan 1 High School to find out the practicality of three-dimensional atomic balls. The method used to analyze data uses qualitative and quantitative descriptive techniques. The results showed that the validity of three-dimensional atomic ball teaching media for atomic structure material was obtained from the results of a media expert's assessment of 95.19% with very valid criteria, and the material expert's assessment was 81.23% with very valid criteria.The practicality test results were obtained from teacher responses of 92.5% with very practical criteria, and 81.41% student responses with very practical criteria. Based on the results of the study it can be concluded that atomic ball teaching media in three dimensions of atomic structure are worthy of being used as learning media by teachers and students.
