This paper reports on five secondary school mathematics prospective teachers' conceptions of "extreme point." The analysis of the data addressed students' definitions, examples, and evaluation of given examples, with special attention to the related domain. Written assignments and individual interviews uncover salient, erroneous concept…

This research paper aims to propose a novel didactic sequence inspired by an historical/epistemological study of the evolution of spectroscopy and in particular of colorimetry. The working principles of the historical color comparators and the visual color matching method, first proposed by Duboscq, stimulated us in the development of a five-step…

This study aims to determine the need for multitiered diagnostic instruments to identify misconceptions and their causes, as well as multi-representational profiles in chemistry lessons starting from grade 10 in the initial to the final material for grade 12. The data analysis technique used in this research is descriptive, namely descriptive…

Understanding the photosynthesis concepts is challenging due to its abstract nature, often leading to student misconceptions. This study aims to identify and analyze misconceptions among science and social studies students using the image analysis method. A total of 78 students (32 science, 46 social studies) participated, selected through a…

This study aimed to develop a comprehensive diagnostic tool for assessing upper-secondary school students' understanding of isomers, expanding upon existing two- and three-tier conceptual diagnostic methods. By incorporating 'Confidence Rating Factor' tiers within the answer and reason sections, a four-tier test was designed and developed. This…

The purpose of this study is to reveal middle school students' model understanding and information sources of incorrect model related to basic astronomy topics included in the Turkish middle school science curriculum. The study is a descriptive study focusing on qualitative data. The sample of the study includes 197 students (aged 12-13) attending…

This study aims to explore the middle schoolers' common naive conceptions of AI and the evolution of these conceptions during an AI summer camp. Data were collected from 14 middle school students (12 boys and 2 girls) from video observations and learning artifacts. The findings revealed 6 naive conceptions about AI concepts: (1) AI was the same as…

Middle school students (n = 144) worked with an applet specially designed to introduce the concept of function without using algebraic representations. The purpose of the study was to examine whether the applet would help students understand function as a relationship between a set of inputs and a set of outputs and to begin to develop a…

This study aims to determine the alternative conceptions that middle school students may have about the structure of celestial bodies, celestial events and the motions of celestial bodies. Since qualitative and quantitative methods were used in the study, the study method is mixed. Since quantitative data were collected first and qualitative data…

Misconceptions occur as a result of learners' wrong beliefs and experiences, and because subsequent learning is built on these misconceptions, they cause new concepts to be learned incorrectly. Studies show that students have problems in making sense of many mathematical concepts in mathematics teaching processes and this situation can be…

Chemistry is a difficult subject for many students. The content is challenging, and students often enter chemistry classes with preconceived ideas about chemical phenomena which may or may not align with scientific ideas (Gabel, 1999; Johnstone, 1991, 1993; Nakhleh, 1992). The purpose of this study was to understand high school students'…

There is a strong relationship between the quality of education, teachers' decisions and instructional actions, and knowledge. All of them have an important role outcome of the lesson and students' learning. The focus of this study was to discover how the process of students' learning or incapability of learning was affected by teaching practices.…

Contemporary secondary science education is characterised by a greater inclination towards the constructivist paradigm of education and the development of inquiry-oriented teaching. The basic principle of this paradigm is the dynamic modification of preconceptions towards the desired level given by the school curriculum. This places particular…

Bullying continues to be a concern in the field of education among school aged students, including individuals with disabilities. The areas of exploration in this basic qualitative study were the characterizations used by students, the ways in which they perceive and experience bullying, and ways in which they react to social situations. Social…

Previous investigations into first year calculus students' understandings of tangent lines have revealed common misconceptions arising either from students' prior experiences with the topic or from the treatment of the subject in the calculus classroom. This study seeks to examine in-service secondary mathematics teachers' conceptions of tangent…
