Abstract

The influence of cooperative learning type TAI based on chemoentrepreneurship to entrepreneurship motivation and conceptual understanding of students on colloidal system concept. Colloidal system concept was a concept that requires highly analysis with mastery of concepts that must be understood and require students practice in daily life. Learning will be more meaningful and provide a deep understanding of the learners when learning adapted to the characteristics of the subject matter. One effective solution was implement the cooperative learning type TAI based on chemoentrepreneurship. This study aimed to determine the influence of cooperative learning type TAI based on chemoentrepreneurship to entrepreneurship motivation and conceptual understanding of students. The study design used was pretest-posttest control group design, the sampling technique used cluster random sampling. The population in this study were all students of grade XII IPA SMA AL-Hamzar, Thatwas 50 students were divided into an experimental group of 26 students and a control group of 24 students. Entrepreneurship motivation analysis technique using multivariate test obtained scores of experimental group 63%, 74% and score of control group 66%, 68%. While conceptual understanding data using multivariate test with SPSS 16.0 for windows which scores obtained from initial test and final test on the conceptual understanding was no difference between the experimental group and control group that why used T test. Results obtained there was significant influences of cooperative learning type TAI based on chemoentrepreneurship to entrepreneurship motivation and it had no influence on students' conceptual understanding with sig = 0.304 > 0.05. So it can be concluded that there was no influence of cooperative learning type TAI based on chemoentrepreneurship to conceptual understanding of students.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh Media Animasi Submikroskopik (MAS) terhadap kemampuan representasi siswa pada setiap sub materi pokok larutan penyangga. Penelitian ini menggunakan nonequivalent pretest-posttest control group design. Hasil penelitian menunjukkan bahwa peningkatan (N-gain) kemampuan representasi siswa kelas eksperimen lebih tinggi (p=0,002) dibandingkan kelas kontrol. Selain itu, rata-rata N-gain kemampuan representasi siswa kelas eksperimen lebih tinggi daripada kelas kontrol pada setiap sub materi pokok. Konsep komponen larutan penyangga mengalami peningkatan tertinggi di kelas eksperimen (rata-rata N-gain = 81,21%). Konsep pH larutan penyangga mengalami peningkatan tertinggi di kelas kontrol (rata-rata N-gain = 76,42%). MAS memuat konsep larutan penyangga pada level submikroskopik dengan jelas sehingga dapat membantu siswa memahami konsep-konsep pada level makroskopik dan simbolik. Berdasarkan hasil penelitian ini disimpulkan bahwa MAS dapat meningkatkan kemampuan representasi siswa pada setiap sub materi pokok.

This study used a nonequivalent pretest - posttest control group design. The results showed that an increase (N-gain) representation capabilities experimental class students was higher (p = 0.002) than the control class. In addition, the average N-gain representation of students' ability for experimental class higher than control class on each sub subject matter. The concept of buffer components experienced the highest increase in the experimental class (the average N-gain = 81.21%). The concept of pH buffer solution experienced the highest increase in the control class (the average N-gain = 76.42%). MAS includes the concept of a buffer solution at submicroscopic level so clearly that it can help students understand the concepts of the macroscopic and symbolic levels. Based on the results of this study concluded that the MAS can increase representation of students' abilities in each sub subject matter. Keywords : animation media, submicroscopic, capabilities, representation

Abstract

Pandemi Covid-19 membuat sistem pembelajaran di kelas menjadi terbatas sehingga siswa dituntut untuk belajar lebih mandiri. Akan tetapi, sumber belajar memadai yang mendukung kemandirian belajar kimia di SMAN 1 Batulayar masih sangat kurang. Penelitian ini bertujuan untuk mengembangkan modul pembelajaran kontekstual terintegrasi Augmented Reality untuk meningkatkan keterampilan berpikir kritis siswa pada materi ikatan kimia. Penelitian ini termasuk metode Penelitian dan Pengembangan. Tahapan penelitian mengikuti desain pengembangan model ADDIE yang terdiri dari lima tahap, yaitu analisis (Analysis), desain (Design), pengembangan (Development), penerapan (Implementation), dan evaluasi (Evaluation). Subyek penelitian adalah siswa SMAN 1 Batulayar yang berjumlah 40 orang. Instrumen dalam penelitian ini adalah angket dan tes uraian. Data kelayakan modul dan tanggapan siswa diperoleh dari angket lalu dianalisis berdasarkan persentase, sedangkan data keterampilan berpikir kritis didapatkan dari tes uraian lalu dianalisis menggunakan paired sample t-test dan skor gain ternormalisasi (N-gain). Adapun hasil penelitian ini antara lain: 1) modul dinyatakan sangat layak dengan rerata skor 90%, 2) modul dapat meningkatkatkan keterampilan berpikir kritis siswa yang ditunjukkan oleh nilai signifikan 0,00 pada taraf kepercayaan 95% dan skor N-gain 58% dengan kategori sedang, dan 3) siswa memberikan tanggapan sangat baik terhadap proses pembelajaran menggunakan modul. Dengan demikian, modul pembelajaran kontekstual terintegrasi augmented reality telah berhasil dikembangkan.

Abstract

Most of the students had difficultyin understanding the concept of chemistry  which is abstract and cannot connect the concepts studied with the phenomena in everyday life.This is because the instructional media and learning models used by the teacher do not pay attention to submicroscopic representations and do not link chemistry with the environment around students.This study aims to develop Chemical Interactive Multimedia (CIM) based on PBL (Problem Based Learning) to improve students' Generic Science Skills (GSS). PBL-based CIM was developed on the concept of salt hydrolysis in a tutorial format. This study was a Research and Development using the ADDIE design. The research procedure consists of five stages, namely Analyze, Design, Development, Implementation, and Evaluation. The PBL-based CIM effectiveness test against the GSS of MA Darul Habibi NW Paok Tawah students was carried out at the implementation stage using a one-group pretest-posttest design. The instrument used was in the form of a questionnaire to obtain eligibility data and student responses, as well as a description test to obtain KGS data. CIM based on PBL feasibility data will be analyzed using a five-scale absolute norm, student responses were analyzed descriptively, and GSS data were analyzed using a normalized gain score (N-gain). The validation results show that PBL-based MIK has an average score of 92% which means it was very feasible.The limited trial of 12 students stated that PBL-based CIM met the aspects of appearance, readability, language, and ease of use very well.The results of PBL-based CIM trials in learning can increase students' GSS which is indicated by an average N-gain score of 58% in the moderate category.Therefore, it can be concluded that PBL-based MIK was successfully developed in the very feasible category and could improve students' GSS.
