Abstract

This research aims to develop and obtain Web-based learning media that meets the eligibility requirements according to BSNP criteria, determine the increase in student competency by using the developed Web-based media and determine the percentage of student responses to Web-based media used in lectures on the topic of instrument analysis. This research method is a research and development method using the ADDIE model. Web-based media was validated by media experts and material experts, then the valid media was presented to 26 Chemistry Education students at Medan State University to see the influence of the Webb media developed and get responses on the web-based media used. The research results show that the Web-based learning media developed meets the BSNP eligibility criteria with an average percentage of 91.25%. The use of Web-based media can increase student competency in lectures on the topic of Instrument Analysis, namely 75% for experimental classes that use Web media and 56% for classes without Web media. Learning outcomes using Webb media are better than without using Webb media and student responses to the use of Webb-based media in lectures Topic evaluation Instrument analysis is very high. Thus, over all the Web-based media developed is good for use in lectures on the topic of Instrument Analysis, to provide students with learning experiences in using the Web.

Abstract

This study aims to determine the presence of student misconceptions in redox material, misconceptions in each concept of redox material, and factors causing student misconceptions in redox material in class XII MIA SMA N 2 Percut Sei Tuan. This research is a quantitative descriptive research. The sampling technique in this study used purposive sampling technique. The samples in this study were 32 students of class XII MIA 1 who were selected based on the recommendation of the chemistry teacher. Data collection techniques were carried out using a web-based three-tier diagnostic test, misconception questionnaire, and in-depth interviews (teachers and students). The results showed that the misconceptions identified using the web-based three tier diagnostic test on the redox concept as a whole was 31.718%, while students who experience incomprehension of the concept is 54.687%, students who understand the concept is 13.906% and understand the concept is not sure 1.25%. Students' misconceptions on each concept of redox material are highest on the concept of compound names at 43.8% and the lowest on the concept of equalizing redox reactions with the oxidation number method and the ½ reaction/ion electron method at 26.6%.Based on the results of questionnaires and interviews, each factor has an influence on misconceptions, the biggest misconceptions are teacher factors and teaching methods, namely 21.32% and 21.28%.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh penerapan model pembelajaran Collaborative Creativity yang dipadukan dengan media virtual laboratorium terhadap hasil belajar siswa pada materi asam basa di SMA Negeri 1 Tanjung Beringin. Sampel penelitian dipilih dari populasi menggunakan teknik cluster random sampling. Penelitian ini merupakan penelitian kuantitatif dengan menggunakan desain non-equivalent control group design, melibatkan dua kelas XI yang ditentukan secara acak sebagai kelas sampel. Data penelitian diperoleh melalui tes hasil belajar dan angket respons siswa. Nilai rata-rata pretest yang diperoleh siswa adalah 37,66, sedangkan setelah perlakuan melalui model Collaborative Creativity dan dilakukan posttest, nilai rata-rata meningkat menjadi 85,66. Hasil ini menunjukkan bahwa model pembelajaran tersebut, yang didukung media virtual laboratorium, memberikan pengaruh positif terhadap hasil belajar siswa pada materi asam basa. Selain itu, data angket menunjukkan bahwa 77,83% siswa memberikan respons positif terhadap penerapan model pembelajaran tersebut. Terdapat pula hubungan yang signifikan antara respons siswa dan hasil belajar dengan nilai korelasi sebesar r_hitung = 0.94, yang lebih tinggi dibandingkan r_tabel = 0.36.
