Teacher-centered lecture-style classes predominate in the Republic of Korea. Typically, classes follow a three-stage structure: introduction, development, and wrap-up. This study aims to analyze concepts teachers present in each stage of photosynthesis classes from a conceptual perspective and how these concepts are connected across each stage. To…

Evaluating students' cognitive understanding of core concepts and identifying learning path aligned with their cognitive developmental patterns are critical for enhancing conceptual mastery in chemistry. This study employed the Rule Space Model to investigate students' cognitive characteristics and learning path in comprehending the conceptual…

Dimensional analysis is an algorithm currently in use in almost every chemistry classroom in the United States. Chemistry educators use this procedural tool in the classroom with the intention of providing students with a reliable method to solve many of the relatively simple math problems they encounter. The unintended consequence of using this…

Learning in the classroom is mainly done through verbal interaction. Since science learning is a subject in which it is difficult for students to acquire knowledge on their own, teacher guidance in class is more important. This study aimed to compare teaching and learning concept networks for the ecosystem-related content taught in upper secondary…

Given the widespread presence of competition in educational settings and its complex impact on science learning, how students complete tasks in competitive environments has attracted a wide range of attention. The purpose of this study is to compare students' performance on physics conceptual questions in noncompetitive and competitive…

Trigonometric derivatives are fundamental in both mathematics and physics, yet their correct application, particularly the distinction between radians and degrees, remains a significant challenge for college students worldwide. This study identifies a widespread "blind spot" in understanding trigonometric derivatives and their…

The progress achieved in the models used by future Spanish primary school teachers on the phenomenon of tides is analysed after implementing a modelling-based didactic sequence. It was implemented throughout ten sessions in two classes (N = 88). An open-ended questionnaire was used as a data collecting instrument. Based on prior studies and the…

With the rise of quantum computing, interest has grown in using two-state quantum systems (qubits) at the secondary level to foster students' conceptual understanding. Quantum measurement, in particular, is central to quantum theory and its accurate conceptualization by students is crucial for grasping fundamental quantum principles. However,…

This study investigates the process of students' metacognitive learning about homeostasis, a fundamental biological principle. The research aimed to determine how the metacognitive awareness learning approach (MCLA) affects student perceptions of homeostasis. The research participants were 146 Israeli 10th-grade students (ages 15-16) who were…

Recent studies have reported a growing trend of using student-generated diagrams for assessment in science teaching and research. However, many educators tend to use diagrams to explore students' perceptions of scientists and their work rather than explore conceptual understanding of abstract concepts. In this study, we used diagrams to…

Despite the importance of developing elementary science teachers' content knowledge for teaching (CKT), there are limited assessments that have been designed to measure the full breadth of their CKT at scale. Our overall research project addressed this gap by developing an online assessment to measure elementary preservice teachers' CKT about…

This article describes a comprehensive practical laboratory method for developing an enzyme to more easily measure glyphosate levels in solution. Through this article, undergraduate students of biology majors can conduct research experiments in critical fields by utilizing various techniques, such as chemiluminescence (CL) biosensors with…

This study evaluated recent advances in learning progressions for the concept of matter (LPCM) and explored trends by reviewing the literature on the topic published between 2005 and 2021. A total of 21 studies were reviewed. Fifteen studies were devoted to developing LPCM of varying spans and grain sizes. There were six follow-up studies based on…

Many research studies have shown that lower-secondary school students' scientific literacy depends on their understanding of corresponding scientific concepts. Therefore, it is of great significance to model and assess students' conceptual understanding in learning specific scientific concepts, because it can reflect and diagnose students'…

This article outlines the results from the research on primary and secondary school pupils' conceptualisation of microorganisms. It has been observed from the past few decades that one conceptual model is dominant, in which microorganisms are considered harmful, disease-causing and living in dirty environments. These misconceptions are only likely…
