Contrary to current IUPAC recommendations, the chemical element X should be defined as the nucleus of the X atom. Consequently, different isotopes with their different nuclei belong to different elements, each one with its own physical and chemical properties. This view leads to the conclusion that we no longer have a periodic table of the…

One aim of inquiry activities in science education is to promote students' participation in the practices used to build scientific knowledge by providing opportunities to engage in scientific discourse. However, many factors influence the actual outcomes and effect on students' learning when using inquiry materials. In this study, discourse from…

Basic cardiac electrophysiology is foundational to understanding normal cardiac function in terms of rate and rhythm and initiation of cardiac muscle contraction. The primary clinical tool for assessing cardiac electrical events is the electrocardiogram (ECG), which provides global and regional information on rate, rhythm, and electrical…

Purpose: In this study, researchers applied blended learning program to investigate the success of a blended learning program on satisfaction of the psychological needs, and academic achievement of chemistry students of O-Levels, following curriculum prescribed by University of Cambridge. Design/methodology/approach: Research pattern is…

This research aims to evaluate a workshop using argumentation-based forensic chemistry activities to enhance gifted students' critical thinking. A workshop program, consisting of seven argumentation-based forensic chemistry activities, was conducted with 20 students at a gifted school in Turkey. A qualitative experimental design was used. An…

Chemistry as a discipline in general incorporates abstract concepts, which should be visualized through experiment- and application-oriented methods. It is a well-known fact in Turkey that chemistry class offered by simple and traditional methods cannot be understood by students at a satisfactory level. Such chemical subjects as atoms, molecules,…

The purpose of the study is to investigate the effect of cooperative and individual learning methods on the conceptual understanding at sub-micro level of pre-service science teachers (PST) in equilibrium chemistry. The study was conducted on 52 PSTs. A pre-test/posttest non-equivalent quasi-experimental design was used in this study. Data…

The importance of utilizing spectroscopic techniques for unraveling structural and compositional changes in nonreacting and reacting systems is unquestionable. Nowadays, efforts are directed towards the introduction of relevant spectroscopic techniques to undergraduate students in order to prepare them for future careers in industry and academia,…

Thermodynamic characterization of micelle formation from an ionic surfactant in aqueous solutions is a classic experiment in physical chemistry. The critical micelle concentration (CMC) and the degree of micelle ionization ([alpha)] can be directly obtained by conductimetry, then thermodynamic parameters ([delta]G[subscript m][superscript o],…

Twenty-first century chemistry education researchers reported challenges in chemistry education pertaining to high school chemistry teaching-learning outcomes. Even though all studies intended to improve chemistry teaching-learning outcomes, unfortunately the impact of chemistry education research found not to be much encouraging. A few of these…

Rapid campus closure and unexpected transition to emergency online teaching of a large first year chemistry unit provided an opportunity to explore the level of student engagement and factors associated with success in this online transition. Here, we compared the standard offering in 2019 to the online version in 2020 by examining the completion…

The aim of the study is to compare learning styles of students in the department of chemistry education in education faculties and learning styles of students in the department of chemistry in faculties of science or faculties of arts and sciences in Turkey. The study group of the study is comprised of 1291 undergraduate students in total from the…

The prime purpose of this investigation was to improve Pre-service Chemistry Teachers (PCTs) understanding of reaction related concepts of Aliphatic Hydrocarbons (AHCs). Participants were 12 PCTs selected from a pool of 87 second year PCTs taking Introductory Organic Chemistry course in Arbaminch college of Teachers Education, Southern Nations,…

An understanding of acid-base reactions is necessary for success in chemistry courses and relevant to careers outside of chemistry, yet research has demonstrated that students often struggle with learning acid-base reaction mechanisms in organic chemistry. One response to this challenge is the development of educational applications to support…

The free radical chlorination of an alkane experiment is often used in the undergraduate laboratory curriculum to introduce students to the free radical mechanism, substituent effects, intermediate stability, and the relative reactivity of radicals. In this experiment, students monochlorinate multiple alkanes and analyze the reaction mixture using…
