Educational tools like EdPuzzle, PlayPosit, and Kaltura have gained recent attention, as they purportedly empower educators to incorporate questions, quizzes, and discussions into instructional videos. However, there is no empirical evidence on how or under what circumstances these platforms may impact students' learning. A quasi-experimental…

This study aimed at determining the category and analyzes the mental models of the students from three senior high school clusters (low, medium, high) on the solubility and solubility product topic, knowing students' opinions on chemistry subject, knowing learning methods and assessment that teacher used in solubility and solubility products…

This study aims to investigate the effect of the teaching model developed for hot conceptual change on middle school 7th-grade students' understanding of the Nature of Science (NOS) aspects. In this qualitative and exploratory study, activities were carried out with 24 students of two classes in a village school in the South Marmara region using a…

Genetics plays an increasing role in modern life as evidenced by the development of revolutionary techniques such as CRISPR-based genome editing and the rise of personalized genome services. However, genetics is difficult to learn; known issues include its abstract nature, different scales, and technical language. Pedigree analysis is a…

This study investigated preservice teachers' levels of mathematics anxiety before and after a mathematics methods course. Changes were measured using manipulatives and other activities to make mathematics concepts more concrete and meaningful. Both quantitative and qualitative measures were utilized. Informal discussions, informal interviews, and…

This study investigates if a force-based teaching approach, based on quantum mechanical principles and developed in a lesson study, would enhance the understanding of chemical bonding among upper secondary school students. The teaching approach was based on research on the teaching and learning of chemical bonding. The study included first-year…

In this paper we focus on Norwegian first-year engineering students' interpretations of differentials and definite integrals. Through interviews with 15 engineering students, we investigated how the students interpreted the different symbols involved in the Fundamental Theorem of Calculus (FTC), as displayed in the textbook used in their calculus…

This article focuses on developing the idea process in visual art education by using digital peer feedback. In the school subject visual art, the visual idea process, e.g. when students sketch their ideas, is an important phase in a project. When an idea takes form, there is the possibility for considering the idea in a new way, for others to…

Within two sections of science methods for elementary and middle-school teachers, an embedded, multi-case study design was employed to explore whether teaching rehearsals would better prepare preservice teachers (PSTs) to implement explanation-driven science instruction. A teaching rehearsal allows PSTs to practice teaching a segment of their…

Involving undergraduate STEM majors in authentic research has been cited as being an imperative goal in advancing the field of science and preparing students for careers and post-graduate educational programs. An important component of authentic research that is often overlooked is student understanding of the Nature of Science (NOS) and how this…

The aim of this study is to explore the possibility of introducing the general notions of function and inverse function through a mathematical activity on linear functions, focusing on the quantitative meaning associated to the connection between a relation and its inverse. We present a genetic decomposition, that is, a viable cognitive path for…

Cinquain is a poetic form, or stanza, of five lines that do not rhyme, which follows some strict rules. Cinquain is also considered to be a training means, a method, a technique, an instrument used for reflection, for synthesis of all knowledge on a particular topic (a being, an object, an ensemble of objects), towards developing one's creativity.…

Fostering students' bidirectional conception of the equal sign (viewing the equal sign as indicating an equivalence of two sides rather than a 'show result' symbol) is challenging, and students' misconception of the equal sign is persistent. Some studies mention that in China, the pedagogical approach to introducing the equal sign supports…

This paper investigates what instructional factors influence conceptual understanding (CU) of signals and systems for senior undergraduate engineering students. Previous results show students in signals and systems courses typically gain little CU, though evidence-based instructional practices, such as active learning, can increase gains in CU.…

Although there has been extensive research on students' understanding of the particulate nature of matter (PNM), there is still a lack of research on contexts that can be used to teach this challenging topic. In a previous design-based research study, the authors developed a teaching-learning sequence (TLS) on the PNM in the context of crystal…
