We present an example of a novel, model-based approach to instruction in which learners constructed a representation of a specific phenomenon, evaluated their representation, and then revised it, via an abstraction process, to construct a model. The example took place in high school in the context of solution chemistry. The aim of the instruction…

The purpose of this study is to determine the relationship between Turkish high school students' perceptions of learning environment, conceptions of learning biology and achievement goal orientations. In order to determine the relation among these three sets of variables, canonical correlation analyses were conducted. A total of 398 high school…

This research focuses on chemistry teachers' enacted pedagogical content knowledge (ePCK) in equilibrium in chemical reactions. The enactment dimension of this pedagogical content knowledge (PCK) encompasses enacted knowledge and skills as well as those embedded in practice concerning the Refined Consensus Model of PCK, the most recent PCK model…

In this study, it was aimed to determine high school students' cognitive structures regarding to the immunity, infection, allergy and autoimmunity. In this study, it was tried to reveal the cognitive structures of high school students on immunity, infection, allergy and autoimmunity just before COVID-19. The study was carried out with 77 students.…

The purpose of this study was to delve into the interaction between pre-service chemistry teachers' pedagogical content knowledge (PCK) and content knowledge (CK) while teaching electrochemistry. Two pre-service chemistry teachers enrolled in practice teaching course in chemistry education program participated in the study. All PCK components were…

The aim of this study is to investigate the effect of active learning on students' achievement in the unit of magnetism. It is important to create proper teaching environments in order to ensure the active participation of students in learning processes. Many different methods and techniques may be used for active participation. Detailed…

For abstract concepts to be well understood, students need to be familiar with the concepts and able to associate them correctly. Students cannot make scientific explanations on the subject unless they can establish relationships. This study aimed to determine the understanding level of 11th-grade high school students on "gases" in terms…

This research aims to draw a picture of chemistry lessons based on students' opinions in Hakkari, Turkey. The research design is a case study. An open-ended qualitative questionnaire consisting of 15 questions was used. The questionnaire was applied to 463 tenth- and eleventh-grade students studying at high schools in Hakkari. The data obtained…

One needs higher order thinking skills in positioning perspectives for any kinds of problems that affect one's view of life in order to develop a fundamental scientific understanding. For this reason, science teaching requires thinking skills instruction to be included in classes. This study aimed to observe the effects of student-centered…

Although many studies are analyzing the effect of the STEM model on students' cognitive characteristics, it is known that there are not many studies conducted especially on its impact on students' conceptions of learning (COL), and it is thought that there is a need for these studies as well. It is necessary to determine how COL, which may vary…

The aim of the present research is to determine the current situation in the readiness levels of 11th grade high school students for self-directed learning, to examine the effectiveness of laboratory activities developed with with mobile technology integrated into the 5E learning model in various chemistry subjects on students' self-directed…

The informal learning environment and the station technique provide students with learning environments where they can be active and materialize the abstract terms. With this regard, the purpose of the study was to determine the contribution of activities, which are carried out through the station technique in informal learning environments…

The purpose of this study is to disclose the units and topics including the concept of water within 9th, 10th, 11th and 12th grades' biology textbooks that were chosen by the Ministry of National Education (MoNE) Head Council of Education and Morality (HCEM), and provide an overview of the whole content that mentions the concept of water. This…

In this study, the impacts of teaching modern physics topics according to textbooks that are prepared based on two different physics curricula implemented in Turkey on students' success, problem-solving skills, and attitudes were examined. The sample of the study consisted of 80 high school students studying in the 12th grade. Within the scope of…

The purpose of this study is to investigate the effect of MagAR, an instructional material for teaching magnetism using augmented reality and sensing technology, on students' academic achievement and learning process, and to identify students' views about augmented reality. An embedded mixed-method approach was employed in this study. The study's…
