This study determined the influence of the competency of teachers and the laboratory environment in an online setting on the students' science process skills using mixed methods approach-convergent design. Participants of the study were 2nd year students from different Higher Education Institutions in Region XI, Philippines. Further, to gather…

An exploratory study was to determine the effectiveness of discussion sessions as a teaching strategy of thermodynamics in basic physical chemistry of fundamental concepts in this area as spontaneity by explaining students according to their ideas. A previously validated questionnaire was used as an instrument on thermochemistry, enthalpies of…

The study diagnosed chemistry teacher trainees' difficulties in naming and writing structures of spiro and bicyclic compounds. The case study design was conducted in a constructivist environment to enhance chemistry teacher trainees' ability to construct, represent, and interpret the structural formulae of spiro and bicyclic compounds. Purposive…

The low Cumulative Grade Point Average of most chemistry undergraduates results in their low achievement and motivation which poses a threat to the production of future chemistry teachers. The diversity of this problem has resulted in several suggestions concerning the application of Google Meet strategy to determine its efficacy in ameliorating…

This paper reports on a study that sought to improve pre-service science teachers' performance in the International Union of Pure and Applied Chemistry (IUPAC) nomenclature of aliphatic hydrocarbons using flipped classroom instructional approach (FCA). The study employed a single group pre- and post-test action research design. The sample size…

This study aimed to investigate the effect of the analytical chemistry laboratory (ACL) course, designed, and conducted according to the flipped learning approach (FL) on prospective science teachers' (PSTs) meaningful understanding and interpretation of knowledge in the context of the environment. Seventy-three second grade PSTs participated in…

Chemicals used in academic teaching laboratories, research institutions, and industrial facilities are mostly dual-use chemicals. They provide many desired benefits but at the same time may cause adverse effects to human health and environments. In the case of Somalia, there are gaps in terms of chemical security (CS) awareness and…

This study aimed to examine the views of preservice science teachers on concept map use in a General Chemistry II class. The study was conducted with 47 preservice science teachers. In the study, an interview form grounded on determining their views on concept maps and comprised of open-ended questions, was used as the data collection tool. In…

A problem-based learning (PBL) methodology was implemented to a project, whose main objectives were to discuss and apply the Twelve Principles of Green Chemistry to the study of poly(vinyl alcohol)'s cross-linking reaction with dicarboxylic acids. The five participating students were oriented to be responsible for their own learning and the…

The aim of this paper was to investigate the effect of the use of science, technology, and society (STS) issues through flipped and traditional learning environments on students' motivation to learn chemistry as well as their chemical literacy (CL). Two freshman engineering classes totaling 89 students taught by the same instructor enrolled in a…

This study developed an e-resource for six topics and six activities for CHE 242 that could be implemented through the hybrid learning approach. The research employed the analysis, design, development, implementation, and evaluation model but particularly focused on the analysis phase only, in this study. One hundred and two students who enrolled…

The purpose of this study was to investigate the influence of a microteaching lesson study on pre-service chemistry teachers' collective pedagogical content knowledge (PCK) regarding solubility concepts. Three pre-service chemistry teachers participated in this study. Data were collected by means of lesson plans, semi-structured interviews,…

Molecular orbital diagrams are commonly taught and used for describing chemical bonding chemistry courses including courses at the college level. Misconceptions that occur when students construct and/or use these diagrams are difficult to anticipate, diminish the diagram utility, and limit student learning. In this exploratory study, a combination…

Although fundamental chemistry acts as a prerequisite for fully comprehending imperative aspects of biology, Bielefeld University is one of three universities in North Rhine-Westphalia, Germany that does not require majors or minors in biology education to complete classes in general chemistry, before fulfilling graduation requirements. A study…

In this study, diagnostic worksheets adopted from the Royal Society of Chemistry and microscale chemistry activities were employed to investigate teacher trainees' understanding of chemical compounds. The framework for the study was hinged on the constructivist theory. Participants in this study were 36 1st-year undergraduate teacher trainees of…
