Analisis Kesulitan Belajar Siswa dalam Mata Pelajaran IPA dan Upaya Penanganannya di MTs N 1 Kepulauan Sula

This study aims to identify and analyze students' learning difficulties in the subject of Natural Sciences (IPA) at MTsN 1 Kepulauan Sula and the measures to address them. Employing a qualitative approach with a descriptive case study method, data were collected through participant observation, in-depth interviews, and document analysis over eight weeks. The findings indicate that students struggle with understanding abstract concepts such as force, motion, energy, and atomic structure due to insufficient teaching aids and practical exercises. Limited resources and facilities, such as inadequately equipped laboratories and restricted access to information and communication technology (ICT), also hinder the teaching and learning process. Low student motivation, varying levels of academic ability among students, and inadequate parental involvement in home learning are additional factors affecting learning difficulties. Proposed measures include enhancing teaching quality through teacher training, utilizing local resources, and strategies to boost student motivation. Differentiated learning approaches to address varying academic abilities and increased parental involvement are also recommended. These findings provide insights into the challenges of teaching IPA in remote areas and recommend developing educational policies better suited to local contexts.

Student Acceptance Study of PhET Simulation with an Expanded Technology Acceptance Model Approach

Phet simulation is a computer-based practicum simulation medium that helps to increase students’ engagement and understanding through concept visualization. Even though there have been numerous studies on the Technology Acceptance Model (TAM) related to Phet simulation, the TAM study of Phet simulation combined with certain learning methods is rarely observed. We propose an advanced version of TAM by including the external variables of system quality, user characteristics, and instructor. This study is a quantitative design with a descriptive, explanatory type. This model was tested using an online questionnaire disseminated to 49 students that finished taking basic natural sciences subjects using Phet simulation based on problem-based learning. The result showed that system quality has an effect on perceived usefulness, perceived ease of use has an effect on behavioral intention of use, behavioral intention of use has an effect on actual usage, and there is no relationship between instructor quality on perceived usefulness. Grit on perceived ease of use, learner anxiety, and perceived usefulness on the behavioral intention of use. These findings have implications regarding user acceptance of Phet simulation combined with certain learning methods, specifically problem-based learning.

Research skills modules for further education college based top-up degrees

This case study investigated to what degree the research skills needed for college based top-up degrees differ from each other. The four academic areas studied ranged from natural and formal science subjects to social science and visual arts. They were explored by means of a thematic analysis of both their individual module handbooks on research skills and interviews with lecturers on these modules. The results were compared against the relevant subject benchmark statements, Biglan’s framework of classifying academic fields and related research. The interviews suggest that the research skills development needs of students at top up degree level can be met through a dedicated module in an effective way. Both the handbooks and the interviews intimated that there is a certain amount of overlap when it came to secondary research, which may be effectively met by a suitable librarian. Furthermore it was found that only two dimensions of Biglan’s framework are necessary to explain the needs of detailed ethics consideration for student projects and the existence of primary research tools and techniques peculiar to a certain field. Further work could include the definition of more generic primary research tools and techniques for academic fields where a paradigm consensus is relatively weak.

How much do teachers know about self-regulated learning? To what degree and in what way do they encourage it in students?

IntroductionSelf-regulated learning (SRL) is a multidimensional process that involves personal (cognitive and emotional), behavioral, and contextual components. Teachers, as mediators in socialization, can influence SRL in various direct and indirect ways: by instructing students on effective learning strategies and structuring the learning environment. Most teachers agree that students should be helped to become self-regulated in their learning, however, they are unsure of how to do this, which is why they encourage it to a limited degree. Therefore, the objectives of the research were: (1) to examine how much teachers know about SRL, to what degree and how they encourage it in students; (2) to examine the differences in encouraging SRL with regard to gender, seniority, type of school and status of school subjects they teach.MethodThe research was conducted using an online questionnaire at two measurement points. A total of 251/179 primary and secondary school teachers in Croatia participated in the study. To assess teaching knowledge and methods of encouraging SRL, the questionnaire employed both open-ended questions (“Provide your own subjective definition of self-regulated learning.”; “How you promote self-regulated learning in your practice? Which approaches are most effective?”) and the Self-Regulated Learning (SRL) Encouragement Scale (encouragement of learning planning and learning organization strategies, metacognitive monitoring of learning, elaboration and evaluation, understanding and effort investment).ResultsTeachers only partially know what self-regulated learning constitutes. About two-thirds of teachers have heard of the SRL, but only 14% accurately defines the construct. When defining SRL, they most often emphasize independently regulated/directed learning, and the definitions are mostly partially correct. On the other hand, teachers estimate that they encourage SRL to a significant extent. There are certain discrepancies in the data regarding the methods of encouraging SRL depending on the methodology (qualitative/quantitative). Teachers encourage SRL to a limited extent and provide implicit and indirect SRL encouragement. The results indicate that female teachers and teachers in humanities encourage SRL to a greater extent when compared to natural science and technical subject teachers, and the same goes for elective subject teachers when compared to compulsory subject teachers.DiscussionThe results have theoretical, but also great practical implications when it comes to the implementation of this multidimensional and complex construct in the educational system. They corroborate the theoretical foundations of SRL and SRL encouragement, whilst indicating the need for improving teachers’ knowledge and competencies in regard to SRL encouragement in students.

The Importance of Active, Innovative, Creative, Effective, and Fun Learning Applications On Natural Science Subject At Islamic Elementary School

The active, innovative, creative, effective, and fun learning applications (PAIKEM) learning model comes from the concept that learning should be child-centered and should be fun therefore students are motivated to continue learning on their own without orders and also students do not feel burdened or afraid. For this reason, the pleasurable learning part becomes one of the important aspects of learning. Especially in science learning activities where teachers still use conventional methods, whereas the material in science learning is very interesting to learn when using fun learning. PAIKEM is one of the fun learning methods, besides motivating students to explore, create, and experiment is the goal of PAIKEM learning. This is to support students develop higher-order thinking skills, critical thinking, and creative thinking.

How does the SETS Model Work Through E-Modules to Enhance Students' Critical Thinking Skills? Effectiveness Level of Instructional Materials

Critical thinking skills are 21st century skills that can be improved through the use of appropriate learning models and supported by the prior knowledge that students already have. One of the learning models that can improve critical thinking skills is the SET learning model through the Science E-Module. The purpose of this study was to show the effectiveness of the application of SETS-based e-modules in Natural Science (IPA) subjects with the topic of waves and sound to improve students' critical thinking skills. This study used a quantitative descriptive design with one-group pretest-posttest technique. The sample consisted of 29 students from class VIII.C who were selected through cluster sampling. Data were analyzed using the normalized N-gain method and paired sample t-test. The results showed that the average N-gain of students' critical thinking skills after implementing learning through SETS-based science e-modules on wave and sound material was 0.4, including in the medium category. The average critical thinking skills of students after the intervention (72) were significantly higher than before the intervention (51). In addition, students' response to the SETS-based science e-module on wave and sound material resulted in a score of 90.4% which showed very good criteria. Therefore, it can be concluded that the implementation of SETS-based science on wave and sound materials can improve students' critical thinking skills.

Developing a Scientific Literacy Assessment Instrument for Portuguese 3rd Cycle Students

Teachers and researchers, in accordance with the main Portuguese curriculum documents in the area of Physical and Natural Sciences, agree that the development of scientific literacy is an integral part of basic education and report that the teaching of these skills is taking place in schools. However, few scientific literacy assessment instruments are available to assess students’ proficiency in using these skills. In this article, we describe the design and processes for gathering validity evidence for the development of the Avaliação da Literacia Científica Essencial (ALCE) instrument. The ALCE assesses scientific literacy skills of students at the end of the 3rd cycle of Basic Education, in the cognitive domains of understanding; analysing and evaluating phenomena; problems and everyday situations involving content knowledge and skills developed in the subjects of Natural Sciences and Physical Chemistry. Our validity argument, which includes the gathering of evidence based on the content and internal structure of the instrument and is grounded in the current literature on the validation of assessment instruments, supports the use of the instrument for the assessment of students’ scientific literacy level at the end of the 3rd cycle of Basic Education. The ALCE may be a useful tool to identify possible gaps between the teaching objectives and the students’ scientific literacy proficiency and reflect on the methodologies, lesson plans and strategies used in the classroom in order to change them to better develop the students’ scientific literacy.
