Abstract

The learning process of 2013 curriculum emphasizes on the students skill, it also demands them to be more active and have extraordinary abilities such as creative thinking skills. The purpose of this study is to describe the feasibility of the Students Worksheet with the mind mapping strategy to improve the students creative thinking skills on stoichiometry material. There are tree aspects which were observed in the students worksheets to measure the feasibility, those are content, presentation, and language. This study was conducted based on 4-D development model which has been modified into 3-D (define, design, and develop). The limited trial was implemented on 12 students of X Science 2 in Senior High School 3 Mojokerto. Furthermore, the results showed that from the three aspects of students worksheet which were content, presentation and language were categorized to be very feasible with the percentage 91.88%;93.55%;86.67 % . The students activities and responses were the data that obtained through the limited trials with the percentage 97.62% and 88.02% of each. Moreover, the increasing of the students creative thinking skills and learning outcomes can be seen from the N-Gain value which were 0.74 and 0.75, and belonged to high category. Based on the results it can be concluded that the students worksheet with a mind mapping strategy was feasible and able to improve the students creative thinking skills and learning outcomes on stoichiometry material

Abstract

Hydrocarbons are one of the materials from Chemistry that studies abstract concepts and procedural knowledge such as alkanes, alkenes and alkyas. To study hydrocarbon material, students must master well the concepts related to previous concepts such as the concept of covalent bonding and equalizing reactions. If students do not understand the concepts related to hydrocarbon material, it will be difficult to master the concepts in hydrocarbon material. The learning process at school at this time sometimes also still does not increase student creativity and activity. The application of the Learning Cycle 5E learning model combined with cooperative type TPS (Think Pair Share) and cooperative type STAD can be used as an alternative to developing a more meaningful learning atmosphere in understanding concepts and giving students the opportunity to work together to solve problems. The purpose of this study was to determine: the quality of the learning process using the LC 5E - TPS and LC 5E - STAD models on the topic of hydrocarbons, as well as differences in the cognitive learning outcomes of hydrocarbon students who were taught with these two learning models. This study uses a quasi-experimental design with "Postest Only Group Design". The sample of this study was students of class XI IPA1 and class XI IPA2 of SMAN I Parang in the 2019/2020 school year, each consisting of 21 people. Class XI IPA1 as an experimental class taught with LC 5E - TPS model and class XI IPA2 as an experimental class taught with LC 5E - STAD model. Research data in the form of observations of the quality of the learning process, the results of observations of students 'cooperative abilities and students' post test scores. Research data were analyzed using t test. The results showed that the quality of the learning process by using the LC 5E - TPS model and the LC 5E - STAD model were included in both categories. Students' cooperative skills in both learning models are included in both categories. Cognitive learning outcomes of students in learning with the LC 5E - TPS model are higher than in learning with the LC 5E - STAD model.

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

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.

Abstract

Many chemistry teachers claimed that identifying students' understanding genuinely is challenging due to the limited time available, and the overload works faced. Therefore, constructing an efficient and valid instrument to overcome this difficulty is a must. This study is a part of the big project to produce a robust four-tier instrument to identify students' conception of acid-base properties of salt solution (FTI-ABPS2). The project involved six groups of researchers, and each group carried out the study in 6 different participant groups and schools. This paper outlines the development and validation of a four-tier instrument of Acid-Base properties of salt Solution involving public secondary school students in Malang Regency. The instrument was constructed using the procedure as carried out by Habiddin & Page (2019). Twenty-eight questions were constructed for the instrument. The results show that the instrument is valid and reliable to be implemented further. In-depth analysis regarding content validity, as well as the empirical validity of the instrument in light with the characteristic of chemical concepts (acid-base properties of salt solution in particular), is also discussed.
