Many teachers are confused about how to implement the phenomena-based teaching recommended by the "Next Generation Science Standards" (NGSS Lead States 2013). This article describes one possible approach--purposely repurposing existing activities. This process involves having teachers: (1) Choose a phenomenon that informs the development…

The aim of this laboratory experiment is to utilize graphene oxide (GO) material to introduce undergraduate students to many well-known concepts of general chemistry. GO is a new nanomaterial that has generated worldwide interest and can be easily produced in every well-equipped undergraduate chemical laboratory. An in-depth examination of GO…

Risk is always present in people's lives: diseases, new technologies, socio-scientific issues (SSIs) such as climate change, and advances in medicine--to name just a few examples--all carry risks. To be able to navigate risks in everyday life, as well as to participate in social debate on risk-related issues, students need to develop risk…

This article is a review of research literature on the teaching of concepts in instrumental music education. It is organized in four parts (a) the value of concept teaching in large instrumental ensembles, (b) time spent teaching concepts during rehearsals, (c) approaches to concept teaching, and (d) implications for music education. Research has…

I propose that students pay more attention to the approximations that lead to integral formulas when they study applications of the definite integral. The goal is to focus students on the underlying concepts and the definition of the definite integral--and to steer them away from memorizing formulas. To address this goal, I have written some…

Understanding information organization is a key component to navigating digital library environments as an information professional. While traditionally thought of within the areas of assessment and evaluation, citation indexing is another form of organization and navigation, and learning about it can transform one's knowledge of the information…

The purpose of this article is to explore physical education (PE) teachers' content knowledge of the emerging concept movement capability. Interviews with eight PE teachers were conducted, partly using a stimulated recall technique which involved watching and commenting on video recorded PE lessons. A phenomenographic analysis was used to outline…

The radioactive nature of technetium is discussed using a combination of introductory nuclear physics concepts and empirical trends observed in the chart of the nuclides and the periodic table of the elements. Trends such as the enhanced stability of nucleon pairs, magic numbers, and Mattauch's rule are described. The concepts of nuclear binding…

A narrative inquiry approach was adapted to study teacher's experiences of planning and teaching force and motion topics. Oral narrative data were collected through interview conversations between the researcher and the teachers about their experiences of planning and teaching force and motion concepts. "Narrative analysis" technique…

In this paper, we discuss the results of a case study about the teaching strategies used by three primary school educators to decode Grade 4 science terminology. In South Africa, the study of science is formally introduced to learners in Grade 4. Additionally, Grade 4 is the year when learners transition from being taught in their native languages…

The central dogma of biology is difficult to learn because its microscopic processes cannot be visualized. This study aimed to devise two inquiry activities: 'Button Code' and 'Beaded Bracelet Making,' involving the concepts of DNA replication and protein synthesis based on the Metacognitive Learning Cycle (MLC) for students, and to explore the…

Could Usain Bolt achieve what teachers often fail to do? Could this famous Olympic winner challenge and motivate students to study mechanics and introduce them to the principles of physics in a fun way, outside of the classroom? In order to answer these questions, we "invited" for one semester the world record holder to visit our Greek…

The author's objective for this reply in reexamining opportunity cost was to draw attention to two conflicting definitions of the concept in current use and to argue the case for dropping one of them. The comments of Daniel Arce, Rod O'Donnell, and Daniel Stone might be read as demonstration that the author has failed on both counts. Such a…

In the field of business and technical communication, scholars have called for research on dealing with cultural conflict for a long time. But the limited study on dealing with cultural conflicts, along with the current political context in the United States, calls for efforts to systematically address diversity issues and cultural conflict in our…

The importance, and associated challenges, of faculty ownership and engagement in the assurance of learning (AoL) process are well documented in the literature. The authors demonstrate how schools can further their AoL objectives by encouraging and subsequently supporting organic, faculty-led initiatives. Specifically, we present a case study of a…
