This article presents a Pedagogical Framework for Invasive Species to shift how we understand, teach, and study invasive species, especially when people are responsible for their expansion into new ecosystems. The focus is on a species originating from countries in Sub-Saharan Africa that humans extracted and introduced in certain regions of the…

This study investigated the nature of the pedagogical content knowledge (PCK) development among 22 prospective teachers enrolled in an elementary science methods course. The nature of prospective teachers' PCK development was investigated in relation to their experiences in planning, enacting, and reflecting upon a Physical science lesson. The…

The purpose of this study was to understand how the facilitator affects the participants' perception of the professional development based on the moves they make to engage educators in the learning experiences. The implementation of the Next Generation Science Standards has resulted in the development of a variety of science professional…

Games are highly appreciated by the population, so due to the COVID-19 pandemic confinement we decided to carry out an Internet research of several games, in order to use them for the assimilation of new words of Biochemical students. Games found in puzzle books allow the stimulation of memory, reasoning and other brain capacities, such as keeping…

More research on information and communications technology (ICT) use for teaching and learning is needed, particularly since the almost global transition from traditional face-to-face to virtual classrooms forced by the COVID-19 pandemic. The problem addressed in this current qualitative project study was the reported challenges experienced by…

The intersecting issues that this study addresses are the lack of engagement in civic opportunities for underserved youth and the environmental injustices that disproportionately impact marginalized populations. To address these issues, the purpose of this youth participatory action research (YPAR) investigated how a high school science teacher…

This study synthesized impacts of integrated literacy and content-area instruction (i.e., science, social studies) on vocabulary and comprehension outcomes in the elementary years (i.e., kindergarten through fifth grade). A systematic search of the extant literature identified 35 (quasi)experimental studies. Random-effects models were used to…

The COVID-19 pandemic has highlighted the importance of incorporating distance learning for long periods. However, few studies have addressed strategies to overcome the limitations caused by the lockdown. In this study, we report an active learning experience on the topic of chemical kinetics, using two "flipped class" approaches,…

The goal of this dissertation project is to use embodied learning--an emerging approach to supporting student engagement--as a focal point to demonstrate how a multidimensional engagement framework can help us understand, evaluate, and design for new ways of learning. The project is situated in the context of third-grade students learning about…

The widely explored but still unresolved question about the contribution of the application of different ways of performing experiments in the integrated natural sciences is addressed in this research. The aim was to determine the contribution of demonstration hands-on experiments (DHE) and student hands-on experiments (SHE) in relation to…

Background: The Next Generation Science Standards (NGSS) call for the integration of engineering content and practices in elementary science curricula, yet little is known about elementary teachers' preparedness to do so or their views on teaching engineering. Purpose/Hypothesis: The purpose of the current study was to explore K-5 teachers'…

On the basis of recent advances in battery research and technology, we have developed a novel laboratory exercise centered on an organic--inorganic battery using the redox chemistry of the organic molecule anthraquinone-2,7-disulfonic acid disodium salt (AQDS). Although most commercially available batteries are based on inorganic redox couples,…

In this paper, we derive an equation for the distance covered by a free-falling body as a function of time valid for any arbitrary distance. The equation, interestingly, yields exactly the time according to the Kepler's third law in the limiting case of very large distance compared to the radius of the Earth. The equation, of course, reduces to…

Existing accounts of student thinking about mechanical wave propagation and superposition emphasize that students sometimes treat wave pulses as objects, saying, for example, that pulses bounce off of one another when they meet. In this paper, we present a context in which students explicitly reason about pulses as not-objects, instead describing…

A student-choice model course redesign was used to counteract a large increase in student enrollment, improve the quality of instruction, and preserve student success. This model is an instructional technique that allows students to choose how to engage in a course. Using this model in a first-semester college-level general chemistry course,…
