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…

The diversity of scientific methods has received increasing attention in the field of science education. This paper aimed to investigate how preservice chemistry teachers perceive scientific methods and their diversity. Based on the theoretical framework of Brandon's Matrix and previous research, two tasks (i.e., Task 1 "understanding of the…

We aim to graphically analyze the depth of conceptual understanding behind the Force Concept Inventory (FCI) responses of students, focusing on three questions (questions 1, 15, and 28). In our study, we created and implemented subquestions to clarify and quantify the students' reasoning steps in reaching their responses to the original FCI…

Purpose: This article presents several potential concerns with the common usage of the term "fluency" in the study of "stuttering" and people who stutter (or, as many speakers now prefer, "stutterers"). Our goal is to bridge gaps between clinicians, researchers, and stutterers to foster a greater sense of…

Scientific misconceptions are ubiquitous, and in our era of near-instant information exchange, this can be problematic for both public health and the public understanding of scientific topics. Refutation text is one instructional tool for addressing misconceptions and is simple to implement at little cost. We conducted a random-effects…

Refutation texts are designed to facilitate the revision of inaccurate knowledge; however, studies have documented backfire effects wherein respondents become less accurate when exposed to a factual correction compared to another. Here, we explored whether epistemic emotions mediated knowledge revision or backfire processes when reading…

This study investigated the stability and persistence of prospective elementary teachers' conceptual understanding of average speed. A questionnaire containing two questions about average speed was administered to the prospective teachers prior to their admission to an elementary science methods course (pretest) and at the end of the course…

This article describes a study of 149 preservice chemistry teachers' misconceptions of concepts related to a reduction-oxidation reaction. A mixed-method approach was used to obtain data through the ROXCI (Redox Concept Inventory) instrument and interviews. Result indicated that the highest misconceptions were for item number 10 (4.03% or only 6…

When any object, such as a glass of water, a greenhouse or the Earth's atmosphere, stays at a steady temperature, the amount of energy entering the object is equal to the amount of energy leaving it. This is considered in equilibrium. This equilibrium changes when the amount of energy entering does not equal the amount of energy leaving.…
