Textbooks are essential learning resources for both teachers and students, but they often contain misconceptions that can affect students' understanding of key concepts, particularly in biology. Misconceptions can arise from inaccurate or incomplete information, and they may lead to incorrect conceptual understanding. The clarity and accuracy of…

The study investigates secondary students' understanding of "orbital" and "electron cloud" concepts in different quantum contexts (for values of the ?principal quantum number n = 1 and n = 2) on the basis of their verbal and pictorial representations, evaluating also their consistency. Participants, which were 192 12th-grade…

In the present study, text presentation in biology textbooks was analyzed with respect to misconception and elements of conceptual change towards the learning of "Cell Structure". Content analysis of the lesson "Cell Structure" in five biology textbooks of Grades 11 and 12 across selected educational boards in Asia like the…

This 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 aims to determine the effect of peer instruction on students' attitudes towards chemistry and in-class discussion, and to examine students' opinions regarding peer…

This paper is twofold. First, it examines the misconceptions held by students about atoms. Second, it determines the suggestions of the instructors (academics and teachers) to overcome these misconceptions. The study adopted a case study research method. A questionnaire was administered to 288 students and a semi-structured interview was conducted…

Rapidly occurring advancements in molecular genetics, such as recent developments in epigenetics, are challenging traditional genetics as it is taught at schools. For example, the adoption of epigenetics--which provides molecular mechanisms for the environment to directly alter phenotypic variation--would mean that pivotal tenets in genetics…

The 21st-century mathematics classrooms should equip learners with well-grounded knowledge and thinking skills pertaining to geometry. However, Euclidean geometry remains one of the challenging, if not the most difficult topic for many learners. As a result, the purpose of this article is to interpret Grade 12 learners' learning difficulties in…

This paper discusses the significance of model-based teaching on the topic of ionic and metallic bonding in Year 12 Chemistry in a New Zealand secondary school. Based on the conceptualization of the sub-macro level understanding of the bonding structure and properties of ionic and metallic compounds, models and drawings were used as an effective…

The concept of angles is important for future geometric knowledge (Arslan et al., 2016; Moore, 2013; Yigit, 2014). However, although Piaget (1948) suggests angles lead to the discovery of lines, angles are typically taught later in schools, after points, lines, and planes (Charles, 2011). Therefore, the way in which angles are taught can affect…

Conceptual understanding of calculus is crucial in the fields of applied sciences, business, and engineering and technology subjects. However, the current status indicates that students possess only procedural knowledge developed from rote learning of procedures in calculus without insight of core ideas. Hence, this paper aims to assess students'…

Through a descriptive exploratory research design, the current study purposed to diagnose students' misconceptions of acid-base concepts. A Three-Tier Diagnostic Test (TTDT) with 20 items was administered to 72 Thai and 64 Indonesian grade 12 students in the science program. The semi-structured interview was used to probe their responses to the…

The aim of this study was to develop a three-tier concept test to determine high school students' conceptual understanding in terms of chemical bonding, and at implementing a reliability and validity study for the test. A total of 175 high school students participated in the research. A three-tier test of 15 questions was employed in the study.…

This phenomenographic case study attempted to determine the alternative and misconceptions of learners in selected concepts in Physics. The research adds another dimension to understanding alternative conception in kinematics by qualitatively determining how learners describe/define a distance of 0m, a displacement of 0m, a speed of 0m/s, a…

Background: The context-based approach (CBA) is one of the approaches that allow learning to take place with real and related context, and this has increasingly become more popular. Purpose: The purpose of this study is to investigate the effect of the REACT strategy of the CBA on remedying 12th grade students' alternative conceptions of…

There are various types of instructional media related to Valence Shell Electron Pair Repulsion (VSEPR) but there is a lack of diversity of resources devoted to assessment. This research presents an assessment and comparison of students' understanding of VSEPR theory before and after tuition involving the use of the foam molecule model (FMM) and…
