Abstract

This study aimed to analyze the effectiveness of the atomic structure module based on guided discovery learning integrated with TPACK on improving the chemical literacy skills of phase E students in high school. The research applied the type of quasi-experiment with pretest-posttest control group design. The population includes phase E students of class X SMAN 1 Sungai Penuh who are studying chemistry in the 2024/2025 academic year, as many as seven classes. Samples were taken using a purposive sampling technique, and the experimental class X.D and control class X.F were selected. Chemical literacy test instrument in the form of essay questions. The data obtained were analyzed using the n-gain test and hypothesis testing with the 't' test. The results of data analysis obtained the n-gain value of the control class and experimental class, respectively, 0.20 in the low category and 0.35 in the medium category. The hypothesis test results obtained tcount > ttable, which is 3.43> 2.009. The chemical literacy ability of the experimental class is significantly higher than that of the control class. So the atomic structure module based on guided discovery learning integrated with TPACK effectively improves the chemical literacy skills of SMAN 1 Sungai Penuh phase E students.

Abstract

This study aims to analyze the validity, practicality, and effectiveness of the acid-base e-module based on guided discovery learning on students' digital literacy skills. The development model used is the Plomp development model. The developed e- module was validated by three lecturers and two chemistry teachers. The module's practicality test was carried out by three chemistry teachers and 33 high school students. The module's effectiveness test was carried out using the pre-experimental method with a non-equivalent control group design. The validity test is explained using Aiken's V formula. The overall validity test results were obtained of 0.91 with a valid category. The results of the e-module practicality test carried out by teachers and students were 89.4 and 87.09% with a very practical category. The average N-Gain value in the experimental class was 0.75, which is in the high category. Based on the results of data analysis, it can be concluded that the acid-base e-module, based on guided discovery learning that was developed, is valid, practical, and effective in improving the digital literacy skills of Phase F (Grade XI) high school students

Abstract

This study aims to analyze student learning outcomes in chemical bonding material and analyze the factors that influence low student learning outcomes. The type of research conducted is descriptive research. The subjects of the study were students of phase F3 class XI SMAN 12 Padang in the semester July-December 2024. The sample determination was carried out using a purposive sampling technique. The instrument used was a two-tier diagnostic test of 15 questions. Data obtained from the analysis of student learning outcomes in chemical bonding material showed that 36.7% of students had not reached the KKTP where there were several learning objectives that had not been achieved by students, namely determining the process of forming single, double and triple bonds, then on the learning objective of distinguishing polar and non-polar covalent bonds, then on the learning objective of determining the formation of coordinate covalent bonds in several compounds. The causes of low student learning outcomes were caused by internal and external factors, but external factors were more dominant in causing low student learning outcomes. ABSTRAKPenelitian ini bertujuan untuk menganalisis hasil belajar peserta didik pada materi ikatan kimia dan menganalisis faktor-faktor yang mempengaruhi rendahnya hasil belajar peserta didik. Jenis penelitian yang dilakukan adalah penelitias deskriptif. Subjek penelitian yaitu peserta didik fase F3 kelas XI SMAN 12 Padang pada semester juli-desember 2024. Penentuan sampel dilakukan dengan teknik purposiv samplin. Instrumen yang digunakan tes diagnostik two-tier sebanyak 15 soal. Data yang didaptkan dari analisis hasil belajar peserta didik pada materi ikatan kimia didapatkan sebesar 36,7% peserta didik belum mencapai KKTP dimana terdapat beberapa tujuan pembelajaran yang belum dicapai oleh peserta didik yaitu menentukan proses terbentuknya ikatan tunggal, rangka dua dan rangkap tiga, selanjutnya pada tujuan pembelajaran membedakan ikatan kovalen polardan non polar, selanjutnya pada tujuan pembelajaran menentukan pembentukan ikatan kovalen koordinasi pada beberapa senyawa. Penyebab rendahnya hasil belajar peserta didik disebabkan oleh faktor internal dan eksternal, namun faktor eksternal lebih mendominasi dalam menyebabkan rendahnya hasil belajar peserta didik.

Abstract

Revolution industrial 4.0 learning is an digitalization of era, especially in the field of education so that technology-based teaching materials are needed that can increase student activity in learning. This study aims to analyze the validity, practicality and effectiveness of the acid-base titration e-module based on guided discovery learning for class XI SMA. The research method used is educational design research with a plomp model consisting of a preliminary research stage, a prototyping stage, and an assessment phase. The research subjects consisted of 8 validators, 6 people in the small group and 18 students in the field test. The research instruments used were validity questionnaires, practicality test questionnaires and student answer sheets on e-modules. Data were analyzed using Aiken's V formula and descriptive statistics. The results of the content validity test and obtained the average value of Aiken's V of 0.95 with a valid category. The results of the construct validity test and media expert validation obtained the average value of Aiken's V 0.89 in the valid category and 0.95 with the valid category. The results of the one-to-one evaluation show interesting e-modules, clear letters and easy-to-understand language. The results of data analysis in the small group test obtained an average percentage value of 87% in the very high category and 88% in the field test stage in the very high category. This data is evidenced by the ability of students to answer e-module questions at the small group stage and field test of . Based on the data analysis, it was concluded that the acid-base titration e-module based on guided discovery learning for class XI SMA was valid, practical and effective.

Penelitian menggunakan metode pre-eksperimental dengan desain one group pretest-posttest yang dilaksanakan pada satu kelas XI di SMA Negeri 5 Padang. pengambilan sampel menggunakan Teknik purposive sampling, dengan jumlah sampel 25 siswa.. Instrumen yang digunakan berupa angket literasi digital, tes pilihan ganda dan lembar observasi guru. Data angket literasi digital diolah dengan menggunakan skala likert, data instrument tes pilihan ganda diolah dengan uji n-gain, normalitas dan hipotesis . Hasil dari penelitian ini diperoleh rata-rata skor literasi digital siswa mencapai 81,4% dengan nilai n-gain sebesar 0,703 yang berada pada kategori sedang, serta hasil uji Wilcoxon menunjukkan perbedaan yang signifikan antara skor pretest dan posttest (sig. < 0,001). Temuan ini menunjukkan bahwa media pembelajaran berbasis AR efektif dalam meningkatkan literasi digital siswa, terutama pada aspek akses digital, visualisasi informasi, dan literasi saintifik. Meskipun demikian, efektivitas media masih dipengaruhi oleh kesiapan perangkat teknologi dan pengawasan guru dalam penggunaannya. Penelitian ini merekomendasikan integrasi AR secara lebih luas dalam pembelajaran sains sebagai inovasi pedagogis untuk memperkuat kompetensi digital siswa dalam menghadapi tantangan era digital.

Jenis penelitian yang dilakukan adalah penelitian deskriptif. Subjek penelitian yaitu peserta didik fase F2 kelas XI SMAN 12 Padang pada semester Juli-Desember 2024. Penentuan sampel dilakukan dengan teknik purposive sampling. Instrumen yang digunakan tes pilihan ganda sebanyak 20 butir soal, angket dan wawancara. Data yang didapatkan dari analisis hasil belajar peserta didik pada materi konsep mol didapatkan sebesar 38,2% peserta didik belum mencapai KKTP di mana terdapat beberapa tujuan pembelajaran yang belum dicapai oleh peserta didik yaitu menentukan hubungan antara mol, jumlah, partikel, massa molar dan volume molar. Selanjutnya pada tujuan pembelajaran menentukan konsep mol dalam menentukan rumus kimia, serta menentukan pereaksi pembatas pada sebuah reaksi. Untuk penyebab rendahnya hasil belajar peserta didik yaitu disebabkan oleh faktor internal dan eksternal, namun faktor eksternal lebih mendominasi dalam menyebabkan rendahnya hasil belajar peserta didik.
