Many educators are already knowledgeable about and skilled in best practices. And much of what is happening in developmentally appropriate programs exemplifies "brain compatible" practices. Being educated in the connections between best practices and brain compatibility is an important part of the knowledge base of early childhood educators. Just…

Many studies in the chemical education literature report students' alternative conceptions in chemistry and the difficulty they present for future learning. In this paper, we review existing diagnostic tools used to uncover students' alternative conceptions in chemistry and suggest that there are two fundamental issues with such instruments,…

The "Theory of Special Relativity" is widely regarded as a difficult topic for learners in physics to grasp, as it reformulates fundamental conceptions of space, time and motion, and predominantly deals with situations outside of everyday experience. In this paper, we describe embedding the physics of relativity into a computer game, and…

The major science education reform documents emphasize the need for K-12 students to have a robust understanding of nature of science (NOS), and inservice teachers consequently need to develop their NOS teaching repertoires. This study investigated the extent to which science teachers were willing to adopt new strategies and activities for…

Students have problems with understanding, using and interpreting graphs. In order to improve the students' skills for working with graphs, we propose Manual Video Measurement (MVM). In this paper, the MVM method is explained and its accuracy is tested. The comparison with the standardized video data software shows that its accuracy is comparable…

This is the second brief in a series, "Building a Post-Care Service System in Child Welfare: Lessons Learned from the Frontlines of Implementation Science in Catawba County." This brief describes how implementation science principles informed technical assistance strategies used in Catawba County to support the full and effective use of…

Development of a scientifically literate citizenry has become a national focus and highlights the need for K-12 students to develop a solid foundation of scientific reasoning abilities and an understanding of nature of science, along with appropriate content knowledge. This implies that teachers must also be competent in these areas; but…

Scientific ecological knowledge (SEK) is a powerful discipline for diagnosing and analyzing environmental degradation, but has been far less successful in devising sustainable solutions which lie at the intersection of nature and culture. Traditional ecological knowledge (TEK) of indigenous and local peoples is rich in prescriptions for the…

As student-teacher-scientist partnerships become more widespread, there is a need for research to understand the roles assumed by scientists and teachers as they interact with students in general and in inquiry learning environments in particular. Although teacher roles during inquiry learning have been studied, there is a paucity of research…

The purpose of this study was to investigate how WebQuests can be used in physics classes for teaching specific concepts. The study had three stages. The first stage was to develop a WebQuest on Newton's second law. The second stage involved developing a lesson plan to implement the WebQuest in class. In the final stage, the WebQuest was…

Studies of high-school science course sequences have been limited primarily to a small number of site-specific investigations comparing traditional science sequences (e.g., Biology-Chemistry-Physics: BCP) to various Physics First-influenced sequences (Physics-Chemistry-Biology: PCB). The present study summarizes a five-year program evaluation…

The time-dependent oscillator describing parametric oscillation, the concept of invariant and Noether's theorem are important issues in physics education. Here, it is shown how they can be interconnected in a simple and unified manner.

We propose a laboratory learning pathway, suitable for secondary school up to introductory undergraduate level, employing the VnR dynamic modelling software. It is composed of three increasingly complex activities dealing with experimental work, model design and discussion. (Contains 4 footnotes, 1 table and 5 figures.)

A classroom activity is presented in which students are challenged to find matches between the United States two-letter postal abbreviations for states and chemical element symbols. The activity aims to lessen negative apprehensions students might have when the periodic table of the elements with its more than 100 combinations of letters is first…

The covariant Maxwell equations are derived from the continuity equation for the electric charge. This result provides an axiomatic approach to Maxwell's equations in which charge conservation is emphasized as the fundamental axiom underlying these equations.
