The purpose of this study was to work out the effect of the employment of chemistry learning modules based of colligative nature of the answer to boost of scholars independent learning attitudes. Population of this study was senior high school School PSKD 7 Depok by purposive sampling tecnique which was class XII with thirty students. Design of this study is one group pre non tes post non test group experiment. Data collection tecniques with questionnaries of 20 statement items and likert scale option. In processing data used the SPSS programs. The results of t paired test concluded that value of t count is bigger than the worth of t Table (-18.83> -23.80). Furthermore, it's also known that the importance value or post-nontest probability value (p-value) of 0,000 is smaller than 0.05 (0.000<0.05). It means there is effect of the use of chemistry learning modules based of colligative nature of the solution to improve of students independent learning attitudes. Based on the gain test to increase of students independent learning attitudes is in the high category, namely 0.82. Thus Guided Inquiri Based Chemistry Teaching Module are needed in learning nature of colligative solution. Keywords: Module; guided inquiri; learning

Publisher : Pascasarjana Universitas Negeri Medan

Practicum is an important element in chemistry. In chemistry learning with practical methods students are given the opportunity to be creative, find, or prove a phenomenon that he experienced and the concepts his learned. Therefore, it is important to develop the learning method using practicum to accommodate the progress and needs of the times so that learning is close to students so that learning becomes meaningful. In this research, the development of digital integrated chemistry practicum modules based on simple practice is carried out. The research sample consisted of 248 students and 26 chemistry teachers, and was validated by 3 expert judges. In the initial stage, the module developed is validated by expert judges. The validation results show that the module is categorized as valid in terms of content eligibility, language feasibility, and presentment eligibility with an average score of 3.81 (scale 4). In the final stage, a module testing is conducted for chemistry students and teachers in the form of collecting responses. Chemistry teacher response results indicate that the module is feasible to be used as a source of student learning on chemistry practicum class XI high school even semester with an average score of 3.78 (scale 4). The results of the students' responses showed that the module was appropriate for them to use as a source of learning on chemistry practicum with an average score of 3.79 (scale 4). The results of student responses on the presentment eligibility aspect showed the highest value of 3.98 (scale 4), the module developed was presented digitally integrated which can be accessed online.Keywords: Chemistry; e-module; practicum; simple-practice

Practical learning which is generally carried out in the laboratory is one of the important lessons in the science learning process, especially chemistry. The Covid-19 pandemic has caused practical learning activities to not be accommodated in real laboratories. This situation encourages the creation of practical learning innovations, namely the use of virtual labs. In this study, students' learning interest in the use of virtual labs is described which is integrated with the use of e-modules on colloidal material. Based on the results of data analysis, 74.55% of students were interested in using the virtual lab, 10.90% very interested, 12.73% quite interested, and 1.82% lack of interested. These data indicate that the majority of students can make good use of the virtual lab and are able to optimally elaborate on the learning process. However, virtual labs are not intended to replace real laboratories but can be used as supplements and media to support learning in real laboratories.Keywords: Colloids, Practicum, e-module, Virtual Lab

This study aims to determine the effect of explicit instruction learning models and the percentage of student learning outcomes improvement in chemistry. Explicit instruction learning model is the free variable while the dependent variable is learning outcomes. This research method is a quasi experiment with the research design nonequivalent control group design. The population of this study were students of Senior High School 42 Jakarta, the sample was selected by purposive sampling technique, consisting of two classes, namely class XI MIA 1 as the experimental class and XI MIA 2 as the control class. The results of the ttest show that the sig. (2-tailed) is smaller than the α value, namely sig 0.000 < sig 0.05, so learning using the explicit instruction model has a significant effect on improving chemistry learning outcomes on hydrocarbon compound material. In addition, the use of explicit instruction learning models can improve student learning outcomes by 19% when compared with the use of conventional learning models (TCL).Keywords: Explicit instruction, Quizizz, Chemistry learning, Learning outcomes

Perencanaan merupakan salah satu unsur penting pada proses pembelajaran. Perencanaan yang baik umumnya berkontribusi positif pada keberlangsungan proses pembelajaran terutama dari sisi keteraturan. RPP merupakan perangkat perencanaan pembelajaran semester yang disusun oleh guru mata pelajaran. Dengan adanya RPP diharapkan pembelajaran dapat berlangsung optimal dan bermakna. Hasil analisis data menunjukkan bahwa RPP guru kimia yang menjadi sampel pada kegiatan tersebut berada pada kategori baik dengan nilai rata-rata 81,25. Data tersebut menunjukkan bahwa sebagian besar guru kimia sudah memiliki keterampilan yang baik dalam merancang kegiatan pembelajaran yang akan diterapkan di kelas. Dengan adanya keterampilan awal dalam merancang pembelajaran akan membantu guru dalam mengembangkan, merancang, menganalisis proses pembelajaran, mengevaluasi, dan mampu berkreasi menemukan solusi yang tepat apabila pembelajaran tidak berjalan semestinya. Perencanaan pembelajaran berperan penting dalam menunjang kelancaran proses pembelajaran, dengan adanya perencanaan pembelajaran maka siswa dapat mempersiapkan diri sebelum pembelajaran berlangsung. Kendati demikian, proses pembelajaran sejatinya bersifat fleksibel yang dipengaruhi oleh situasi, kondisi, sarana, prasarana, dan stakeholder pendidikan. Perencanaan pembelajaran yang baik tidak menjamin kebermaknaan suatu proses pembelajaran.
