In electromagnetism, to determine the direction of the electromagnetic force and magnetic field, the right-hand rule (RHR) is used. Previous researches show that students have difficulty in applying the RHR. This research is aimed to find out the factors which make it difficult for the students to apply the RHR. To achieve this, qualitative case…

Some level of understanding of and about nanoscience and nanotechnology (NST) has been suggested as being relevant in up-to-date scientific literacy for all. Research scientists working in these fields are central in current efforts to inform and engage the public in NST. Earlier research has shown that scientists can contribute to authentic…

This study investigates the use of specific educative features for supporting the teaching of nature of science (NOS) during read-alouds of elementary science trade books. Educative features are components of educative curriculum materials that aim to increase teachers' content knowledge and support effective instructional practices. Understanding…

Low cost, open-source analytical instrumentation has the potential to increase educational outcomes for students and enable large-scale citizen science projects. Many of these instruments rely on smartphones to collect the data, mainly because they can effectively leverage a dramatic price-to-performance ratio of the optical sensors. However,…

In recent years, research on students' scientific competencies has generated much discussion. According to the PISA 2015 Assessment and Analytical Framework, both scientific competencies and attitudes towards science -- interest in science, valuing scientific approaches to enquiry (or epistemological beliefs about science), and environmental…

The survey method was employed for investigating understanding nature of science (NOS) between general science education and science pre-service teachers. Independent t-test and two-way ANOVA were used for testing hypothesis. Results found that both of two programs rated understanding NOS ranges disagree and highly agree levels in different items.…

Comfort whilst camping overnight during outdoor pursuits is based on pain free and warm sleeping arrangements and is highly dependent on the performance of the sleeping bag and sleeping mat. In adventurous and challenging situations, performance can contribute to safety and expedition success. From the manufacturer's point of view, thermal…

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…

Inquiry skill is the most important factor in the development of the scientific processes of prospective science teachers. The objective of this study is to research the effect of using inquiry-based activities on the development of scientific process skills of prospective science teachers. The research group of the study consists of students…

A guided inquiry-based experiment exploring the regioselectivity of the hydration of phenylacetylene is described. The experiment uses an acidic gold(III) catalyst in a benign methanol/water solvent system to introduce students to alkyne chemistry and key principles of green chemistry. The experiment can be easily completed in approximately 2 h,…

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…

The concept of reactance in AC electrical circuits is often non-intuitive and difficult for students to grasp. In order to address this lack of conceptual understanding, classroom exercises compare the predicted resistance of a power tool, based on electrical specifications, to measured resistance. Once students discover that measured resistance…

The eight science and engineering practices outlined in the Next Generation Science Standards (NGSS) are key to student science learning. However, there is limited guidance for teachers on what these practices "look like" in instruction across different grade ranges and topic areas. Further, there is little existing guidance for teachers…

Nature of science (NOS) is a key component of scientific literacy, so science teacher education on NOS is critical to ensure students' scientific literacy. According to mainstream NOS literature, explicit and reflective interventions are recommended to effectively teach NOS. This paper presents an experience for the initial education of secondary…
