Abstract

Nowadays, the lack of a facility is one of the main problems in physics education for developing countries. To solve the problem by use of the modern technology which develop around the world obviously, a teaching material in learning alternating current (AC) circuit as one of the most difficult theory in physics for secondary school students has been investigated using a soundcard oscilloscope with the laptop computer. Experiments for the electrical resonance in LCR circuits have been investigated using the sound card oscilloscope; experimental results were compared to that measured by the conventional oscilloscope system. As expected, the investigated soundcard oscilloscope experiments show a good performance; the magnitude of electrical current as a frequency response proves the effectiveness of the teaching material in physics education that shows kind of limited function of soundcard oscilloscope that utilizes as a benefit in a simple experiment. For the further work, the teacher can utilize and develop this software for the other teaching materials for example related to traditional music or traditional apparatus which tend to find around student’ home or school, so students can understand more deeply about the concept of alternating current in many cases and more interesting classes can be created.

Abstract

Research shows that students’ misconceptions interfere with students’ learning of scientific concepts. Meanwhile, the significant effects of students’ misconceptions on their achievement has been a concern for teachers who strive to find ways of dealing with the misconceptions. This study was conducted to explore Cambodian students’ misconceptions of states of matter (Solid, liquid, and gas), which main aimed to investigate what type of misconceptions which they held in the concept of characteristics of solid, liquid, and gas. Data was collected using a 15 multiple-choice two-tier test which was administered on 330 junior high school students in Kampot province, Cambodia. In this test, students’ responses were categorized into three: correct answer, misconception, and incorrect answer. Data analysis through descriptive statistics showed the frequencies of each students’ misconceptions. Students’ responses to the items revealed that 20 misconceptions were held by less than 50% of the students whereas 4 misconceptions were held by more than 50% of the students who took the test. Interviews with some of the students revealed the nature of students’ understanding of the concept of states of matter. Two main conclusions were derived to explain these results: 1) students tend to attribute macroscopic view to microscopic view and 2) students believe matter exist unless they see.

Abstract

The integration of science, technology, engineering, and mathematics (STEM) in K-12 education is widely recognized as a critical means to ensure future prosperity, security, and a skilled workforce in these fields. This integrated STEM approach entails teaching these four STEM disciplines in a cohesive manner. However, several barriers have arisen, including the lack of a clear consensus on the key features of implementing integrated STEM education effectively. There remains uncertainty about which science subjects should be integrated with the other three disciplines and at what level within K-12 science education this integration should occur. Therefore, this study aims to establish a well-defined framework for teaching science through an integrated STEM approach (ISTEMA) and identify the types of integrated STEM disciplines employed in various educational settings through a systematic literature review. Secondary data, including scholarly journal articles and book chapters, were collected through searches in databases such as the Educational Resource Information Center (ERIC) and Web of Science. Data analysis was conducted using within-case and cross-case analysis methods. The findings of the study revealed that the framework of teaching science ISTEMA generally consists of six elements: inquiry-based, engineering-based, technology-based, problem-based, teamwork-based, and robotic-based learning. This approach primarily focuses on primary and lower secondary education. Engineering and technology content is predominantly integrated into the science subject. In primary education, science and engineering and science and technology are extensively used, while in lower and upper secondary education, science, engineering, and mathematics, science, technology, and engineering, or STEM are commonly employed.
