The development of metaknowledge about models (MKM) and metaknowledge about the modelling process (MKP) are important in pre-service science teachers (PSTs) education. MKM refers to knowledge about the model's entities and its purposes, while MKP refers to knowledge about the components and structure of the modelling process. Assessing MKM and MKP…

Although researchers have extensively studied student conceptions of radioactivity, the conceptions held by preservice teachers on this subject are largely absent from the literature. We conducted a qualitative content analysis of problem-centered interviews with preservice teachers (N=13) to establish which conceptions are held by preservice…

This research report presents the findings of the 2024 Climate Literacy Survey, commissioned by the Department for Education (DfE) to assess the level of climate literacy amongst school leavers leaving secondary education in England.

Wetlands ecosystems play an important role and are relevant to biotic and abiotic factors including survival of humans. Therefore, it is imperative that learners in Lesotho become sensitized to the knowledge about the ecology of wetland ecosystems. Few studies investigated Lesotho students' ecological literacy of wetlands hence this study explored…

Despite the magnitude of the investment in professional development (PD) for K-12 educators and its limited returns, research on PD has typically only focused on effective elements of program design. Little work has been done to explore the role of facilitators or leaders of professional development. However, by better understanding the complex…

Algorithmic systems shape every aspect of our daily lives and impact our perceptions of the world. The ubiquity and profound impact of algorithms mean that algorithm literacy--awareness and knowledge of algorithm use, and the ability to evaluate algorithms critically and exercise agency when engaging with algorithmic systems--is a vital competence…

Researchers have long been interested in the origins of humans' understanding of symbolic number, focusing primarily on how children learn the meanings of number words (e.g., "one", "two", etc.). However, recent evidence indicates that children learn the meanings of number gestures before learning number words. In the present…

The purpose of this study is to determine pre-service chemistry teachers' knowledge of the oxidation number and coordination number in coordination compounds. Data were collected from 31 pre-service chemistry teachers through a 4-question scale, and the second question of the scale consisted of 8 sub-questions. The results showed that the…

In a study of student understanding of negative definite integrals at two institutions, we administered a written survey and follow-up clinical interviews at one institution and found that "backward integrals", where the integral was taken from right to left on the x-axis, were the most difficult for students to interpret. We then…

Although approximately a third of individuals with intellectual and developmental disabilities (IDD) also experience a mental health concern, caregivers often miss early identification of these issues. In this perspective piece, we present an outline for a mental health literacy program that can enhance existing training approaches for caregivers…

Site visits are common in evaluation plans but there is a dearth of guidance about how to conduct them. This paper revisits site visit standards published by Michael Patton in 2017 and proposes a framework for evaluative site visits. We retrospectively examined documents from a series of site visits for examples of Patton's standards. Through this…

Diabetes mellitus is a chronic metabolic disease that affects over 34.2 million or 10.5% of the U.S. population and ranks as the seventh leading cause of death. Tennessee's diabetes prevalence rate is ranked 45th overall in the nation, with 14.9% of the population affected, and in the local area for this project, the rate is greater than 15%,…

My dissertation asks: "What does an Angel Investor learn about the venture capital investment process and how do they learn it?" This is important, because Angels finance the earlier stages of venture investing (referred to as Seed or Series A) and play an instrumental role in the formation, financing, and success of today's leading…

The importance of textbooks and other materials to the educational process cannot be overstated. Unfortunately, the prices on these vital learning materials have continued to grow steadily year over year (Hanson, 2021). Open educational resources (OER), which are "teaching, learning, and research materials that are either (a) in the public…

While understanding the concept of audience is an important step in learning to write, few studies have explored how student writers conceptualize audience in academic and nonacademic settings. This dissertation explores how college students enrolled in a first-year composition course conceptualize and operationalize audience and examines how the…
