Get PDFThis study aims to investigate the applicability and effectiveness of the peer instruction method on teaching the subject of acids and bases at the 12th grade level. In addition, it is aimed to determine the effect of peer instruction on students’ attitudes towards chemistry and in-class discussion, and to examine opinions of students to peer instruction after implementation. The sample of the study consists of 21 12th grade students in a private high school. During the research process, the unit of acids and bases was covered by the researcher with the peer teaching method and implementation was completed in 5 weeks. In this study, which was designed as an action research, qualitative and quantitative data were used together. Quantitative data were collected through acids-bases concept test (ABCT), chemistry attitude scale (CAS), argumentativeness scale (AS), concept questions, and qualitative data were collected through method opinion scale (MOS), semi-structured interview, and observation. The analysis of the data was carried out using quantitative and qualitative methods. The results showed that there was a notable increase in the academic achievement of the students after the implementation. Furthermore, the results obtained from ABCT and semi-structured interviews indicated that peer instruction improved students’ conceptual learning, and also it is effective in eliminating misconceptions. Although the pretest-posttest scores of CAS and AS did not demonstrate a considerable statistical difference, observation and semi-structured interview data pointed out that students’ attitudes towards chemistry and in-class discussion increased positively. At the end of the implementation, it was observed that students’ attitudes towards the peer instruction method are positive and students found it very useful and effective

At the same time, during the implementation of the activity, teachers and students experienced a STEM activity based on the EDP. In the fall semester of the 2022-2023 academic year, this STEM activity based on the engineering design process was planned for Friction force and water resistance in the 5th-grade middle school science course. Then, the activity was implemented in a class of 21 students. The activity was implemented in three class hours. This activity, titled “Let’s Design a Water Slide Boat,” aimed at designing a water slide boat that would be least affected by water resistance and friction force to improve students’ engineering and design skills. This activity was based on NGSS and the objectives and outcomes set in the 5th-grade science curriculum of the Turkish Ministry of National Education
Biology Teacher Candidates Drawings about Circulatory System
Get PDFThe purpose of the drawing method is to reveal the hidden beliefs, attitudes, knowledge and understanding of students without being dependent on words. It is more useful than other techniques in that it is easy to apply and a lot of data can be obtained with a drawing. Some misconceptions can be revealed by asking students to describe or illustrate some objects or phenomena. Biology is mostly concerned with the diagnosis of structures, their interrelationships and their functions. For this reason, it is very important to draw the biological structures correctly. Human circulatory system’ comprehension is a major point in biology education. Because understanding this system is a basis for learning the transport and exchange of substances in the human body, the lymphatic system, gas exchange, and other important biological concepts. The aim of this study is to examine the cognitive structures of biology teacher candidates about the “circulatory system” with the drawing technique. In this study, a case study was conducted to reveal the biology teacher candidates’ drawings in detail. In order to explore biology teacher candidates’ drawing of the circulatory system in detail, their drawings were collected as data through 32 high school students (teacher candidates) in biology education faculty from Turkey. After the drawings were completed, each drawing was effectively scored for the presence or absence of at least one organ/structure in circulatory system. In addition, the drawings were further reclassified, taking into account the pattern of the path of pulmonary and systemic circulations. According to the findings obtained from the drawings of the biology teacher candidates about the circulatory system, it was revealed that the teacher candidates had many misconceptions, mistakes and incomplete information

Professional Learning Community (PLC) in STEAM Education: A Hands-On Workshops Sample
Get PDFSTEAM education puts professional learning communities on the agenda by requiring teacher collaboration along with disciplinary integrity. In this study, a professional learning community in STEAM education was investigated by observing 49 teachers from different disciplines working in different districts during 16 weeks of interdisciplinary training and their practice with students. Teachers’ perceptions of skills teaching self-efficacy, design self-efficacy and perceptions of interdisciplinary teaching were assessed using pre-post tests. The research concluded that the STEAM professional learning community study positively improved teachers’ perceptions of skill teaching self-efficacy and interdisciplinary teaching, but was not sufficient to develop design self-efficacy. It was found that teachers’ views of practice were positive and that interdisciplinary collaboration contributed to this. In light of the research findings, it was suggested that the use of professional learning communities in STEAM education may be an effective example of the interdisciplinary functioning of hands-on workshops
