Identifying contingencies between constructs in a multi-faceted learning progression (LP) is a challenging task. Often, there is not enough evidence in the literature to support connections, and once identified, they are difficult to empirically test. Here, we use causal model search to evaluate how connections between ideas in a genetics LP…

Student understanding regarding topics in upper-division courses, such as biochemistry, is not well represented in the literature. Herein we describe a study that investigated students' reasoning about Michaelis-Menten enzyme kinetics and enzyme inhibition. Our qualitative study involved semistructured interviews with fourteen second-year students…

Magnets are familiar objects and yet magnetism as a concept remains challenging. A casual search of YouTube for magnets reveals a staggering number of videos, interesting demos involving electric and permanent magnets, and entire channels devoted to various uses for magnets. It is far more difficult to find descriptions that can help students…

As students learn physics, they are often required to reason about the behavior of macroscopic and microscopic phenomena, and to synthesize prior knowledge from several different areas of physics to construct understanding of new ideas. This can be a tremendously difficult cognitive task for novice students, especially when the unfamiliar…

How do individuals create a knowledge base over a lifetime? Charles Darwin left detailed records of every book he read from "The Voyage of the Beagle" to just after publication of "The Origin of Species." Additionally, he left copies of his drafts before publication. I use these records to build a case study of how reading and…

The book synergizes research on number across two disciplines--mathematics education and psychology. The underlying problem the book addresses is how the brain constructs number. The opening chapter frames the problem in terms of children's activity, including mental and physical actions. Subsequent chapters are organized into sections that…

Psychological studies of early numerical development fill a void in mathematics education research. However, conflations between magnitude awareness and number, and over-attributions of researcher conceptions to children, have led to psychological models that are at odds with findings from mathematics educators on later numerical development. In…

Quantifying angularity is critical for the study of K-12 school mathematics and beyond; yet, quantifying angularity is challenging for individuals across these grade levels. Using data from a yearlong teaching experiment with ninth-grade students, I address the role of attentional motion in quantifying angularity and present four such motions…

Metamodeling ideas move beyond using a model to solve a problem to consider the nature and purpose of a model, such as reasoning about a model's empirical basis and understanding why and how a model might change or be replaced. Given that chemistry relies heavily on the use of models to describe particulate-level phenomena, developing…

The purpose of this research was to examine teachers' perceptions regarding the concept of curriculum through metaphor analysis. In this research, "phenomenology research design" was adopted. The participants of the research consisted of volunteering teachers (n = 261) working in ten public high schools in the province of Nigde, Turkey.…

Children start to gain concepts from an early age. They are particularly sensitive to what is happening in their close surroundings. As a result of their daily observations, they can create various conceptual information about the Earth, Sun, and Moon. It is thought that the participation of children in the education process is very important for…

EPortfolio use meets institutional reporting requirements and provides an opportunity for students to demonstrate learning, showcase their strengths to future employers, and develop lifelong reflective practice. At the same time, ePortfolio use offers students repeated opportunities to develop the skills necessary for academic progress and…

Reorienting organic chemistry laboratories with an emphasis on systemic thinking can only be beneficial to students. Addressing the challenges of climate change and the development of renewable resources with a fundamental reaction, such as the hydrogenation of an alkene, will allow students to see organic chemistry as a science beneficial to…

Understanding is one of the four key proficiencies in the "Australian Curriculum: Mathematics" and arguably the pivot on which mathematics depends. This case study investigated preservice teachers' understanding and ability to articulate some measurement concepts. Data were gathered from 23 preservice teachers who voluntarily…

In this article, the authors explain how to use the "evidence on the U" strategy to support deep and complex thinking in elementary students, and give examples of scaffolding activities that gradually place much of the responsibility for learning on the students themselves over the course of a year. They also describe how this teaching…
