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…

The study complements previous research on a case study of chemistry lesson plans design and teaching. It has been found that chemistry education in the Gambia has been challenged by ineffective lesson plans design and teaching, and laboratory resources. The consequences have been unsatisfactory learning outcomes. However, what could lead to…

The authors of this article propose a simple exercise of monopoly pricing to illustrate complex theoretical results on the welfare effects of group pricing. By exposing students to this exercise, they aim to bridge a gap between the standard textbook analysis of group pricing and more general results in the literature and clarify some students'…

Over the last years, there is a growing interest in studying students' difficulties with rational numbers from a cognitive/developmental perspective, focusing on the role of prior knowledge in students' understanding of rational numbers. The present study tests the effect of the "whole" or "natural number bias" (i.e., the…

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…

Electricity is a very important concept in learning Physics. Mastering this concept can make learning Physics meaningful and relatable to real life problems. However, literature indicates that students have poor conceptual understanding of concepts about electricity. The current research aims to improve Form 5 (aged 17 years) students'…

The aim of this study was to analyze the direct and indirect relationships between romantic myths of love and teen dating violence victimization (physical and psychological), considering the mediating role of tolerant attitudes toward abuse and the moderator role of gender. A sample of 467 adolescents who had a dating relationship at that time or…

The "Forty Electronic Challenges" is a "discovery learning" and socio-constructivist science activity that has become rather popular in Canada. The article recalls its emergence and development. It discusses its theoretical underpinnings and how it fits into the existing literature. It then gives educators all the guidelines…

We discuss student conceptions of improper integrals and infinity in the context of a second-semester calculus course (in a three-course sequence). Our observations stem from a sequence of activities used in an online course over a three-day period. Throughout the enactment of these activities, students are challenged to develop conceptions of…

Identifying changing patterns of stability and variability is crucial when examining second language development (SLD) from a complex dynamic systems theory (CDST) perspective (Larsen-Freeman, 2020). By studying attractor states, or recurrent patterns of stability, light can be shed on the underlying dynamics of a complex dynamic system (van Geert…

This study explored how a professional development experience changed preschool teachers' perceptions of integrated STEM education. In addition, the research examined what teachers learned about STEM education with this experience. The study employed a qualitative research design, precisely a case study approach. Thirty preschool teachers…

Considering both the ecological niches of fungi and the different benefits they provide to humans, it is expected that students have a high level of scientific knowledge about living things in this kingdom. In the study, it was aimed to examine the learning of secondary school students about living things in the fungi kingdom. The research, which…

The aim of this research is to determine the students' misconceptions of using concept cartoons and to evaluate the lessons taught with concept cartoons according to the students' opinions. The model of the research is the case study, which is one of the qualitative research methods. Participants are a total of 82 students, attending the 3rd grade…

The purpose of this study was to analyze teacher perceptions of the impact of deficit thinking in student course level placement to derive greater insight into the causes of the over-representation of students of color in lower-tracked classes. This study was conducted as a virtual focus group using Google Meet that took place across 3 meetings in…

The Math Kangaroo is one of the biggest international mathematics competitions. In Finland, the number of participants has been around 15,000 in recent years. In this research, we considered Finnish fourth to ninth graders' performance in the Math Kangaroo Finland 2011, 2015 and 2019. We investigated the following problems: What kind of…
