The insufficiency of teachers who teach integrative science, technology, engineering and mathematics (STEM) courses is a major challenge facing science education today. Many teachers lack adequate expertise to combine disciplines and choose effective instructional approaches. This study examines how and to what extent teachers might succeed in…

The recent discovery and ongoing detection of Einstein's predicted gravitational waves offers an exciting opportunity for engaging the general public in science. In order to reach a wide range of people with different science-art identities, levels of physics expertise, age, and gender, the "Celebrating Einstein" festival merges science,…

This study focused on the development and validation of a three-tier multiple-choice diagnostic instrument about the ecological footprint. Each question in the three-tier test comprised by; (a) the content tier, assessing content knowledge; (b) the reason tier, assessing explanatory knowledge; and (c) the confidence tier that differentiates lack…

Understanding student ideas in large-enrollment biology courses can be challenging, because easy-to-administer multiple-choice questions frequently do not fully capture the diversity of student ideas. As part of the Automated Analysis of Constructed Responses (AACR) project, we designed a question prompting students to describe the possible…

For some elementary science teachers, a unit on land and water brings nightmares of dirt and water all over the room. Several Earth science "kits" contain hands-on exercises that allow the students to "get messy" as they manipulate materials; however, these lessons may lack the necessary opportunities for students to ask unique…

There is an urgent need to strengthen undergraduate science students' epistemic knowledge, which requires having the scientists "qua" teachers on board. The divide between scientists' perceptions of science and the perceptions held by those who study science is in this context problematic. Even so, this remains a sorely understudied…

Science, Technology, Engineering, and Mathematics (STEM) education, integrated STEM education, and integrative STEM education are all actively pursued teaching approaches currently being highlighted in the United States and abroad (Sanders, 2009; Semali & Mehta, 2012), and in recent years the increase in interest, engagement, and pressure to…

This study consists of a categorisation of the vocabulary of chemistry, focusing on the terminological difficulties students face when learning this subject. Therefore, this classification intends to provide chemistry teachers an awareness of the language barriers students must overcome in their understanding of this scientific discipline. Two…

The study assessed the effect of concept map on achievement and classroom management of 7th grade students. Three elementary schools were purposively selected in Silchar town of Assam, India. The 7th grade students (n = 36), of 'School I' was assigned to lecture cum discussion approach, 34, students (n = 34) of 'School II' was assigned to Spider…

In formal education, the teaching of natural sciences begins when children are about 12 years old. Teachers justify this with the difficulty and abstraction of concepts in these sciences, and they refer to the theory of child development by Piaget. However, numerous examples from everyday life, from non-formal education, analysis of the…

Academic institutions and research funders have in the last decade devoted considerable effort to developing policies to support academic integrity and prevent misconduct. In this study, we consider the extent to which various initiatives of Canadian federal and provincial (Québec) funders have affected the development of institutional research…

The aim of the present study is to determine pre-service teachers' mental models related to basic astronomy concepts. The study was conducted using a survey method with 293 pre-service teachers from 4 different departments; physics education, science education, primary teacher education and early childhood education. An achievement test with…

The National Association of Social Workers requires social workers to obtain continuing education (CE) after they receive their social work degrees. A large and profitable industry that has emerged catering to this need for CE that is particularly focused on the needs of licensed social workers. Quality control mechanisms in place to monitor the…

The forgotten history of de Broglie waves as themselves artifacts of a Lorentz transform, not physical lengths and frequencies to be transformed, causes confusion for students and others. In this paper the de Broglie wavelength is derived and dependence of de Broglie frequency on velocity explained in terms of Einstein synchronized reference frame…

The classroom jumping ring demonstration is nearly always performed using alternating current (AC), in which the ring jumps or flies off the extended iron core when the switch is closed. The ring jumps higher when cooled with liquid nitrogen (LN2). We have performed experiments using DC to power the solenoid and find similarities and significant…
