This study aimed to develop a standardised instrument for diagnosing science misconceptions in primary school children. Following a developmental research approach using the 4-D model (Define, Design, Develop, Disseminate), 100 four-tier multiple choice items were constructed. Content validity was established through expert evaluation by six…

Curricular analytics (CA) is a quantitative method that analyzes the sequence of courses (curriculum) that students in an undergraduate academic program must complete to fulfill the requirements of the program. The main hypothesis of CA is that the less complex a curriculum is, the more likely it is that students complete the program. This study…

Students experience many difficulties learning the fundamental relationships in Newtonian mechanics, partly due to preexisting mental models that originate from their everyday lives. These preconceptions often persist even after instruction in mechanics and lead to a supposed incompatibility between physics lessons in school and personal…

Attitudes towards learning chemistry have been little studied in secondary school students, especially regarding dimensions related to problem solving, the molecular atomic perspective of chemistry, and real-world connection of chemistry. In the present study, we first aimed to design and assess the psychometric properties of the attitude to…

General chemistry students need to understand the concept of intermolecular forces and use them to predict the properties of materials. To do this, they must create symbolic representations of molecules, relate these to physical observations, and explain them using submicroscopic theoretical constructs. When these concepts are taught separately,…

Although the chemical literature contains many studies of multimedia-based learning and teacher enthusiasm, there is a paucity of research on whether and to what extent teacher enthusiasm in video lectures affects students' learning, especially in chemistry. In this context, this mixed-method study used eye tracking and quantitative analysis to…

College biology courses commonly use diagrams to convey information. These visual representations are embedded in course materials with the expectation that students can comprehend and learn from them. Educational research, however, suggests that many students have difficulty understanding diagrams and the conventions (e.g., labels, arrows) they…

The purpose of this study is to find a way to improve students' performance to solve physics problems by inducing changes in emotion via immediate feedback. To this end, in 2016, we conducted an experiment, doing an interview and survey consecutively. The participants were five second-year male students attending a private high school in Seoul,…

Situational engagement is a key element in promoting students' maintained interest and focused attention in learning. Most research on students engagement has been variable-centered, and only few studies have examined situational patterns of student engagement. The present study used person-oriented approach (e.g., latent profile analysis with…

Enzyme kinetics is the study of enzymatic catalytic rates in biochemical reactions. This topic is commonly taught to life science students in introductory biochemistry courses during their undergraduate education. Unlike most other biochemistry topics, which focus on visual structures of biomolecules and their processes, enzyme kinetics is…

The aim of research was validation of a method for the assessment of cognitive complexity of chemical technology problem tasks. The method included an assessment of the difficulty of concepts and an assessment of their interactivity. As a research instrument for assessing performance, test of knowledge was used. Each task in the test was followed…

Innovative teaching strategies are designing a new and promising landscape in education. They fill lessons with creativity and imagination for either the students or teachers. This article addresses an attempt to make the approach to science easier in a nonscientific environment: primary education at university level. Gamification methodologies…

The present investigation aims to analyze the effect of motivation on students' causal attributions to choose or abandon chemistry when it first becomes optional in the secondary education curriculum in Spain. Attributions to the effect of the family and to the teacher and classroom methodology were found to be common predictors of the choice to…

Dealing with multiple external representations (MERs) in science education is the key to students' understanding of science communication and becoming scientifically literate. It is generally accepted that learning scientific concepts, processes, and principles requires understanding and interacting with MERs. Science can be understood as a…

Chemical processes can be fully explained only by employing quantum mechanical models. These models are abstract and require navigation of a variety of cognitively taxing representations. Published research about how students use quantum mechanical models at the upper-division level is sparse. Through a mixed-methods study involving think-aloud…
