Abstract

21st-century learning demands that students possess critical thinking, creative, and problem-solving skills based on science literacy. However, observations at SMP Negeri 3 Kabila and SMP Negeri 1 Tapa indicate that science learning remains dominated by lecture methods and limited laboratory facilities, resulting in low process skills and student science literacy. This study aims to analyze the effect of implementing the PhET virtual laboratory learning media integrated with the Problem-Based Learning (PBL) model on students' science literacy skills regarding the topic of matter and its changes. This study uses a quantitative approach with a one-group pretest–posttest design, combined with a multi-site, replicated-treatment design. The research sample consisted of 112 seventh-grade students, selected via cluster sampling from two schools: SMP Negeri 3 Kabila and SMP Negeri 1 Tapa. The research instrument consisted of a science literacy test with 10 items that measured the ability to explain scientific phenomena, evaluate scientific investigations, and interpret scientific data. Data analysis used the Kolmogorov-Smirnov normality test, paired t-test (hypothesis test), and N-Gain calculation. The research results showed that the data were normally distributed and that the use of the PhET virtual laboratory media had a significant effect on students' science literacy skills, as indicated by t-values ≥ t-table in all classes. The improvement in skills was also reinforced by the N-Gain value in the moderate category. This shows that PhET-based learning is effective in improving students' science literacy. So, it can be concluded that integrating the PhET virtual laboratory with the PBL model has a positive impact on students' science literacy skills in the topic of matter and its changes and can serve as an alternative learning medium in schools with limited laboratory facilities.

Abstract

Science practicums are an essential component of the Independent Curriculum to develop students’ science process skills, yet their implementation at the junior high school level still faces various obstacles. This study aims to analyze problems in the implementation of science practicums at SMPN 1 Telaga Biru, Gorontalo Regency. A qualitative approach was used, with data collected through observation, semi-structured interviews with four science teachers, and a literature review. Data were analyzed using thematic analysis involving data reduction, coding, categorization, and conclusion drawing. The results reveal three interrelated problems: (1) limited facilities and infrastructure, such as damaged tools and insufficient practicum materials; (2) limited instructional time; and (3) low teacher competency in operating practicum equipment due to minimal training. These constraints reduce the effectiveness of practicum-based learning and hinder the development of students’ science process skills. This study concludes that improving practicum implementation requires integrated efforts in enhancing facilities, time management, and teacher competency. The findings provide a comprehensive basis for improving educational policy and practice, particularly through better resource allocation, flexible scheduling, and continuous professional development for teachers.

Abstract

The low scientific literacy of students in Indonesia is caused by the monotonous learning process that makes students bored with learning. This study aims to determine the effect of a virtual laboratory based on PhET simulation on students' scientific literacy in temperature and heat. This study used a quasi-experimental, non-equivalent control-group design with two experimental and two control classes of seventh-grade students during the 2025/2026 academic year. Data were collected using pre-test and post-test scientific literacy instruments. The results of the independent-samples t-test showed a significance value (Sig. 2-tailed) of 0.000 < 0.05, indicating a significant effect of the virtual laboratory on students' scientific literacy. In addition, the N-Gain analysis showed that the control class was in the low category (0.17 and 0.14), while the experimental class was in the medium category (0.63). The uniqueness of this study lies in integrating a virtual laboratory based on PhET simulations with scientific literacy indicators in teaching temperature and heat. These findings indicate that virtual laboratory media can effectively improve students' scientific literacy. PhET simulation-based virtual laboratories can serve as an effective technology-enhanced learning tool to improve students' scientific literacy, particularly in understanding temperature and heat concepts in junior high school science education.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh penggunaan media Laboratorium Virtual berbasis Physics Education Technology (PhET) terhadap kemampuan literasi sains siswa pada materi zat dan perubahannya di SMP Kabupaten Gorontalo. Penelitian menggunakan metode kuasi-eksperimen dengan desain One Group Pretest-Posttest Design. Subjek penelitian terdiri atas satu kelas eksperimen di SMP Negeri 1 Dungaliyo dan tiga kelas replikasi di SMP Negeri 1 Bongomeme dengan jumlah masing-masing 20 siswa pada tahun ajaran 2025/2026. Data dikumpulkan melalui tes esai literasi sains, lembar observasi, dan angket respons siswa. Analisis data dilakukan menggunakan uji-t dan indeks N-Gain. Hasil penelitian menunjukkan bahwa penggunaan laboratorium virtual PhET berpengaruh signifikan terhadap kemampuan literasi sains siswa. Rata-rata nilai meningkat dari 46,5 pada pretest menjadi 90,3 pada posttest, didukung oleh nilai thitung > ttabel sehingga hipotesis alternatif diterima. Nilai N-Gain berada pada kategori tinggi. Peningkatan terjadi pada aspek menjelaskan fenomena ilmiah, mengevaluasi penyelidikan ilmiah, dan menafsirkan data serta bukti ilmiah. Dengan demikian, media PhET efektif digunakan sebagai inovasi pembelajaran IPA untuk meningkatkan literasi sains siswa.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pendekatan Deep Learning dan penggunaan KIT Mekanika terhadap frekuensi miskonsepsi siswa SMP kelas VIII pada materi getaran dan gelombang. Penelitian dilakukan di SMP Negeri 10 Gorontalo dengan melibatkan tiga kelas, yaitu kelas eksperimen, replikasi 1, dan replikasi 2. Metode yang digunakan adalah eksperimen dengan desain One Group Pretest-Posttest. Pengumpulan data dilakukan menggunakan tes Three-Tier Multiple Choice yang diberikan sebelum dan sesudah pembelajaran. Hasil pengujian statistik menunjukan bahwa terdapat penurunan frekuensi miskonsepsi secara signifikan pada kelas eksperimen (6,78 menjadi 2,59),  replikasi 1 (6,52 menjadi 2,57), dan replikasi 2 (6,22 menjadi 2,3). Nilai n-gain sebesar 0,64 pada kelas eksperimen dan replikasi 1, serta 0,67 pada replikasi 2, termasuk dalam kategori sedang. Temuan ini menunjukkan adanya peningkatan pemahaman konsep dan penurunan miskonsepsi secara konsisten. Dengan demikian, pendekatan Deep Learning dan KIT Mekanika efektif dalam menurunkan frekuensi miskonsepsi siswa pada materi getaran dan  gelombang.
