Geodesy is a very active and essential research discipline in geophysics but it is not a commonly studied subject at the secondary school or junior post-secondary levels. Far more frequently, gravity and gravitational acceleration are discussed, to some extent, in elementary kinematics or classical mechanics courses. This often takes the form of…

We present a critical discussion of how chemistry textbooks treat the electrolysis of water and aqueous salt solutions, based on a survey of general chemistry textbooks in English and Korean at secondary and tertiary levels, also informed by the historical background of 19th-century debates. English-language textbooks present various and…

Science education tries to develop students thinking, linking, analyzing by embodying an abstract concept. The modeling method is used as one of the methods used in science education. This research in 2018-2019 academic year at Kocaeli Vocational School, was applied to students who are taking the course. In this survey, the qualitative method is…

This study aims to find out the effects on pre-service teachers of a constructivist teaching approach aided by use of a Porphyrios-tree. Use of a Porphyrios-tree is thought to be the basis of and most principled conceptual teaching tool to aid meaningful comprehension about concepts of interspecies relationships. The study has a quasi-experimental…

Fermentation is responsible for the production of myriad products across a variety of industrial sectors. In particular, the biomanufacturing industry requires a labor force proficient in fermentation and its associated technologies to drive the production of recombinant protein therapeutics. This paper describes the development of a course that…

Our collaborative action research addresses a challenge in initial teacher education pertaining to the lack of theoretical coherence between teacher candidates' understandings of teaching and learning. The group comprised of three science teacher candidates (Authors 2 and 3) and a university faculty member (Author 1). Through a loosely adapted…

Despite the fact that the sophisticated technologies are a substantial component of children's everyday environment, of the space within which they act, play and learn--the world of complex technological systems (their characteristics, and the knowledge and skills involved in operating, designing and programming them) is almost ignored in the…

Germinating a seed is presumably the first experiment made by a child in his life. So, it has an important place both in child's scientific experience and understanding. Despite the significance of the experiment, the literature indicates that students possess various misconceptions related to the concepts of seed and seed germination. So, it is…

Work, as a concept, is often encountered in daily life, but the meaning of work in physics is closely related to power, force, and energy. Studies made about various concepts and subjects have proved that using words in ways different from their scientific meanings has a negative effect on teaching, and causes conceptual complexities and/or…

Biology and biochemistry students must learn to visualize and comprehend the complex three-dimensional (3D) structures of macromolecules such as proteins or DNA. However, most tools available for teaching biomolecular structures typically operate in two dimensions. Here, we present protocols and pedagogical approaches for using immersive augmented…

Background: Preschoolers' knowledge of the principle of static equilibrium is an important research focus for understanding children's science content knowledge. Hitherto studies have mainly used behavioural observation with small samples. Thus, extending these studies with a validated test instrument is desirable. Aims: The aim was to validate an…

The purpose of this study is to investigate the process of students' construction of scientific explanations through drawing explanatory diagrams. For this, we observed fifth and sixth graders' drawing processes in a gifted science class involving learning physics concepts in mechanics. The analysis was carried out on three pictorial…

In this article we present simple and low-cost experiments about the polarization of light. We use an LCD monitor or an RGB LED light bulb with a Polaroid as a source of polarized radiation, a polarizer sheet as an analyzer, and a smartphone camera to measure light intensities. Thus, using a digital camera to acquire videos students can explore in…

Besides improving students' understanding of scientific concepts, chemistry teaching should also improve students' ability of applying concepts to solve problems. The research aims to explore the effects of modeling teaching on students' proficiency in solving galvanic cell problems. This research used a quasi-experimental design, and the…

When reading scientific information on the Internet laypersons frequently encounter conflicting claims. However, they usually lack the ability to resolve these scientific conflicts based on their own prior knowledge. This study aims to investigate how differences in the trustworthiness and/or expertise of the sources putting forward the…
