Abstract

Evaluation of student abilities in Biology subjects often faces challenges in ensuring that the instruments used actually measure what they are supposed to measure. The data analysis used is the Rasch model, which is part of item response theory, offering a more accurate approach in analyzing evaluation data. This model allows the identification of items that are inappropriate or too difficult, as well as providing more in-depth information about individual student abilities.  Through analysis of instruments and question items from 30 multiple choice questions that emphasize critical thinking skills, the aim of this research is to assess the quality of Biology questions for class X SMA. Testing was carried out using WinStep software and Rasch modeling analysis on 166 students from five high schools/vocational schools. The research method used is quantitative. The results of the instrument investigation show that the issue has very good dependability and the unidimensionality of the instrument is indicated by unexplained changes in the first differentiation. These results show that the Rasch test can help educators in selecting questions that meet the evaluation criteria and contribute to improving the quality of national education. The implications of this research are By applying the Rasch Model, educators can develop more accurate and fair evaluation tools, which are able to identify individual student difficulties and strengths.

Abstract

This study aims to analyze students' scientific argumentation skills in the context of environmental change using Toulmin's Argument Pattern. The topic of environmental change was selected due to its contemporary relevance and inherent complexity, which necessitates robust argumentation. The participants consisted of 76 Phase E (10th grade) students at SMAN 1 Koto XI Tarusan, selected through random sampling. A qualitative descriptive design was employed, with data collected through seven argumentative essay questions and student interviews. The responses were assessed using a rubric based on Toulmin’s components: claim, data, warrant, backing, and rebuttal. The findings revealed that 76% of students exhibited weak argumentation skills, 17% demonstrated moderate proficiency, and only 7% performed at a strong level. The study provides a comprehensive overview of students' argumentation abilities and identifies strengths and weaknesses in their application of Toulmin’s framework. The implications of this research highlight the need for developing more effective instructional strategies to enhance students' scientific argumentation skills, particularly in addressing environmental issues.

Abstract

Education plays an important role in preparing students to face the challenges of the 21st century, one of which is through improving scientific literacy. However, the results of a pre-research questionnaire showed that 70.1% of phase E students at SMAN 1 Pangkalan Koto Baru rarely read materials or work on questions based on scientific literacy, and 50.5% of students had never heard of the term scientific literacy. This has impacted students’ low ability to explain scientific phenomena and interpret data scientifically. Therefore, learning innovations are needed, such as the application of the Problem Based Learning (PBL) model assisted by color coding to improve students’ scientific literacy skills, particularly on the topic of environmental change. This research is quantitative research with an experimental design using a Randomized Control-Group Posttest Only Design. The study population consisted of all phase E students at SMAN 1 Pangkalan, with a sample of two classes randomly selected. The experimental class received treatment using the PBL model assisted by color coding, while the control class used a conventional learning model. Data were collected through a scientific literacy ability posttest and analyzed using normality tests, homogeneity tests, and hypothesis testing. The results showed that the implementation of the Problem Based Learning model assisted by color coding had a significant effect on improving students’ scientific literacy skills. This is indicated by the average posttest score of the experimental class, which was 79.43, higher than that of the control class, which was 68.22. This study concludes that the PBL model assisted by color coding is effective in improving the scientific literacy skills of phase E students on the topic of environmental change at SMAN 1 Pangkalan.

Abstract

21st century education aims to improve students' scientific literacy skills. The results of the PISA study show that Indonesian students' scientific literacy is in the low category. The low level of student scientific literacy is caused by several factors in the education system, such as the curriculum, teachers and students themselves. This research aims to see the effect of the model Problem Based Learning (PBL) in Biology learning on students' scientific literacy abilities at SMAN 2 Pulau Punjung based on three aspects of scientific literacy, namely aspects of context, knowledge and competence. This research is experimental research with methods like an experiment. The research sample consisted of 70 students consisting of two classes taken using engineering purposive sampling. The instrument used is a scientific literacy test. The data analysis techniques used are divided into three, namely normality test, homogeneity test and hypothesis test. Based on the research results, it is known that the hypothesis test results obtained were 0.000 < 0.05. This shows that there is an influence of the PBL model on students' scientific literacy abilities in Biology learning at SMAN 2 Pulau Punjung. This can be seen in the average value of the scientific literacy abilities of students taught using the PBL model which is higher than the average scientific literacy abilities of students taught using the learning model. discovery learning

Abstract

This study aims to examine the development of Student Worksheets (LKPD) based on Discovery Learning through a literature review. LKPD based on Discovery Learning is one of the effective learning media to improve critical thinking skills, problem solving, and students' understanding of concepts independently. The method used in this study is a literature review by examining various reference sources related to the development of LKPD, the application of the Discovery Learning model, and its impact on student learning outcomes from the Google scholar database from 2017 to 2023. The results of the review show that the development of LKPD based on Discovery Learning has a positive influence on the learning process, by increasing active participation and deeper understanding of the material. In addition, analysis of various studies shows challenges in implementation, such as time constraints, teacher readiness, and curriculum adaptation. Therefore, training is needed for educators and adjustments to LKPD to make it easier to apply in various classroom conditions. This study is expected to be a reference for the development of LKPD that is more effective and innovative in supporting Discovery Learning-based learning in schools.
