This article presents and discusses the results of a study that investigates university students' comprehension of the concept of molar concentration, following teaching and evaluation of the subject. The specific problems underlying learning of this concept have not yet been focused on in sufficient detail or depth. A "Reasoning with…

In this paper, the main purpose is to describe the development and use of three flowcharts for identifying types of isomers and naming coordination compounds. The first flowchart is designed to help students identify the type of isomers between the two coordination compounds. The second one is is designed to identify the type of stereoisomerism.…

As an outcome of multidiscipline integration, the polymeric surfactant is of growing importance in modern industry and scientific research. However, the instructional introduction on polymeric surfactants is still insufficient in universities nowadays. In order to effectively guide undergraduates to study polymeric surfactant, a new polymeric…

Science and technology play an important role in modern medicine and experience shows that, although school students and their relatives are likely to have experienced some of the complex procedures available today, they are generally not aware of the science behind them. Demonstrations that link school science to medical procedures can therefore…

The Gatsby "Good Practical Science" report (Gatsby, 2017) identified opportunities to carry out open-ended investigative projects as one of ten benchmarks for good practical science. However, there is currently no requirement for post-16 students in England to have access to such opportunities as this is not required by A-level…

Individuals with a secondary education should have a knowledge level sufficient to make sense of what they read or hear about genetics, and they should be able to think scientifically in evaluation and decision-making processes. The purpose of this study is to identify the basic understanding of secondary education students about genetic concepts…

According to the Next Generation Science Standards, science instructional materials can be efficient as long as they integrate three dimensions: science and engineering practices, crosscutting concepts and disciplinary core ideas. However, research investigating the integration of these three dimensions in the content of school science textbooks…

Science teachers use a large number of visual representations and models in science classes to guide students to understand complex phenomena and to learn to conduct scientific inquiry. Fluent formation and use of visual representation involves metavisualization, which is a process related to metacognition and visualization. However, what kinds of…

Science education researchers have found that instructional design focusing more on learners' affective needs can be powerful in nurturing effective and exciting science learning. This paper reports a qualitative study exploring how learners' situational affective experiences are influenced by the interplay of their habitual affective attributes…

High-performance liquid chromatography is one of the primary techniques covered in the undergraduate analytical chemistry curriculum. This technology report describes the use of a portable capillary-scale instrument that can provide similar performance to a benchtop instrument but generates less solvent waste and enables operation in nonlaboratory…

Students have several misconceptions about thermodynamics. However, an understanding of basic concepts in this branch of physics remains fundamental to explain thermal phenomena. The purpose of this activity was to extend students' conceptual understanding of heat, temperature, energy, and thermal insulators and conductors. Two groups of students…

The COVID-19 pandemic is promoting online education. In this concern, not only online teaching of wet laboratory practices is being challenging, but also online teaching of practices in bioinformatics. Here, I discuss the problematic of online teaching practices in bioinformatics and provide fundamental guidelines, especially oriented for beginner…

Oxygen reduction reaction (ORR),as a multielectron electrode reaction, is an important electrochemical reaction in the field of electrochemical energy storage systems. Herein, a new advanced electrochemical laboratory experiment is designed for undergraduates to master the preparation of oxygen reduction catalytic electrode. Students can use…

Physics teachers around the world are trying to create classroom environments that would allow life science students to be more intrinsically motivated in their work. These efforts include, among others, matching classroom activities to students' interests as well as structurally variable activities to match different student abilities. While…

This article seeks to use Dewey's interpretation of pragmatism and education as a model for how dominant notions of school exemplify a e. The article argues that Dewey sought to commodify nature as a tool for human progress. This aspect of Dewey's beliefs is further demonstrated in the kind of schooling that is being implemented through…
