Abstract

Oftentimes the increase in industrial development is the cause of environmental problems. Environmental problems can be overcome by the presence of humans who care about the environment or have environmental literacy skills. Environmental literacy skills can be instilled from an early age, for example through practicum learning in schools. However, considering that the Covid-19 pandemic is one of the obstacles in carrying out the practice, virtual laboratory-based online learning is carried out. This study was aimed to improve students' environmental literacy through virtual laboratory-based online learning that has been developed.  This research is quasi experiment with pre-test and post-test research design Control Group Design. The total sample of the study was 70 students of class X at state senior high school. The research instrument used was in the form of test questions about environmental changes material and environmental literacy questionnaires. The results showed that the N-gain value of environmental literacy in the experimental class was 29% high, 60% moderate, 11.42% low with the percentage of attitudes 66.62% and 63.43% behavior. Meanwhile, for the control class, the N-gain value was 9% high, 48.57% moderate, 42.85% low and 68% attitude and 67% behavior. This shows that virtual laboratory-based online learning contributes to increasing environmental literacy skills.

Abstract

This study aimed to measure and analyze students’ quantitative literacy (QL) in human coordination system concept. It involved 76 participants (16-17 years old) from the second grade of senior high school at two national schools in Subang, West Java, Indonesia. These participants consisted of 39 males and 37 female students. Their QL was assessed by four essay tests to examine their QL indicators including interpretation, representation, calculation, and analysis through coordination system in human issue. Their answers were analyzed by a QL rubric according to Association of American Colleges and University (AACU) assessment. QL achievement for each indicator was categorized into four levels. The analysis result showed that students’ interpretation, representation, calculation, and analysis were at level 3, 2, 3, and 1, respectively. Based on data analysis, students’ achievement in calculation, interpretation, and representation were categorized as the milestone (mediocre). Meanwhile, their analysis skill was classified as a benchmark or the lowest QL level.

Abstract

ABSTRACTPenelitian pendahuluan menunjukkan bahwa kuliah lapangan Ekologi Umum belum memiliki model penilaian yang dapat secara optimal menilai semua kegiatan mahasiswa. Tujuan penelitian ini adalah untuk mengembangkan "model penilaian" dan untuk mengetahui efektivitas dengan mencoba model dalam kegiatan perjalanan ekologi bidang umum Metode penelitian untuk penelitian kami adalah metode penelitian campuran dengan desain eksploratif. Penilaian dilakukan dari tahap persiapan, selama perjalanan Ekologi Umum lapangan, dan pasca-field trip. kinerja siswa ditentukan oleh diri sendiri dan peer-assessment dengan skor kisaran 0-4. Setelah kunjungan lapangan selesai, pendapat siswa yang terjaring oleh kuesioner dan wawancara. mayoritas siswa ( 90%) menyatakan bahwa "model penilaian" yang berusaha optimal adalah untuk menilai kinerja siswa dan kemampuan kerja ilmiah, meningkatkan keterlibatan siswa dalam proses pembelajaran; mempengaruhi rasa tanggung jawab, interaksi sosial , kepercayaan siswa lain, dan komitmen untuk melakukan pekerjaan yang lebih baik siswa mengaku. memahami kriteria penilaian, tetapi ada beberapa siswa yang tidak suka dengan cara ini dan diasumsikan rekan-rekan mereka tidak cukup kompeten untuk menilai, selain masalah "keadilan ", kritik mengurangi rasa percaya diri, dan merasa buruk menilai teman sendiri. Singkatnya, model penilaian cukup efektif dalam menilai kinerja siswa dalam bidang ekologi umum berbasis inkuiri. Hal ini masih perlu dimodifikasi dalam rubrik penilaian dan strategi penilaian.ABSTRACTPreliminary research indicates that General Ecology field trip does not have a model of assessment that can be optimally assess all student activities. The purpose of this study was to develop a "model of assessment" and to try to determine the effectiveness of the models in ecology field trip activities common research method for our research is mixed research methods to the design of exploratory. Assessment was carried out from the preparation stage, during General Ecology field trip, and postfield trip. student's performance is determined by self-and peer-assessment with a score range of 0-4. After the site visit was completed, students' opinions were netted by questionnaires and interviews. majority of students ( 90%) stated that "assessment model" which seeks optimal is to assess student performance and scientific work ability, improve student engagement in the learning process; affect sense of responsibility, social interaction, trust other students, and a commitment to do the job the better students admitted. understand the assessment criteria, but there are some students who do not like this way and assumed their colleagues are not competent enough to judge, in addition to the problem of "fairness", criticism reduces confidence, and feel bad judge his own friends. In short, the assessment model is quite effective in assessing student performance in the areas of general ecology-based inquiry. It still needs to be modified in the assessment rubrics and assessment strategies.

Abstract

Improving problem-solving skills has been promoted as a helpful strategy in student learning in the 21st century. Field trips are a learning method that can encourage students to interact directly with natural objects in nature. The learning method is expected to improve students' problem-solving skills. In this case, this research was conducted to find the effect of field trips on improving students' problem-solving skills based on a focused strategy. This research is quasi-experimental research using pre-test and post-test designs. The participants in this study were students from two tenth grades of SMAN in Pameungpeuk, Garut, during the 2019/2020 school year. The data obtained were analyzed using the average comparison test, namely the t-test (for parametric data) and the Mann-Whitney test (for non-parametric data) with a value of 0.05. Based on the analysis, the problem-solving skills of students in the two classes increased in the medium category, and there was a significant difference in the problem-solving skills of students in the two classes with a significant value of 0.044. Thus, it can be concluded that a focused strategy-based field trip affects problem-solving skills and can stimulate the improvement of students' problem-solving skills on ecosystem materials. Therefore, a field trip with a focused strategy can potentially be an alternative method for teachers in high school to improve students' problem-solving skills on ecosystem materials.
