A guided-inquiry experiment was designed and implemented in an introductory organic chemistry laboratory course. Students were given a mixture of compounds and had to isolate two of the components by designing a viable workup procedure using liquid-liquid separation methods. Students were given the opportunity to apply their knowledge of chemical…

Part I of this dissertation focuses on investigations of nitrogen oxide plasma systems. With increasing concerns over the environmental presence of NxOy species, there is growing interest in utilizing plasma-assisted conversion techniques. Advances, however, have been limited because of the lack of knowledge regarding the fundamental chemistry of…

The impacts of a technology-integrated formative assessment technique on students' conceptual and procedural knowledge in studying chemical equilibrium are studied in this study. To attain the purpose, a quasi-experimental pretest-posttest strategy nested with a qualitative study method was adopted. The study has three groups: two experimental and…

Though there are a multiplicity of approaches that have been used to promote Nature of Science (NOS) among school students, an approach based on exploration of a scientific discovery indigenous to the sample population, of contemporary interest, and based on a topic outside the school science syllabus seems to be lacking in the literature. This…

In this article, we focus on a set of remote activities regarding simulated juries, judges' evaluations, communication of verdicts, and a post-discussion conversation. These activities aimed to promote learning of the preservice teachers about the differences between remote and in-person teaching in a chemistry teaching methods course. The set of…

This article presents a study conducted at Georgia Gwinnett College (GGC) to explore the use of ChatGPT, a large language model, for fostering critical thinking skills in higher education. The study implemented a ChatGPT-based activity in introductory chemistry courses, where students engaged with ChatGPT in three stages: account setup and…

Results from the Trends in International Mathematics and Science Study (TIMSS) assessments have shown that students in Korea displayed high levels of science achievement. In order to understand those achievement outcomes, a number of studies have examined science teaching in Korea and explored the effects of teaching practices on student…

Mass spectrometry is frequently introduced to undergraduate students as an instrument for both qualitative and quantitative chemical analysis. One of the most common uses of mass spectrometry (MS) is to deduce or confirm a compound's chemical formula, by relying on high-resolution accurate-mass measurements. However, like all forms of instrumental…

Purpose: This paper aims to discuss the knowledge levels, attitudes and behaviours regarding the concept of sustainable development among pre-university programme educators, as well as the potential barriers and opportunities they face in adopting the concept of sustainable development in the teaching of the pre-university level chemistry module…

The Environmental education navigates students towards environmentally friendly life style and securing a quality of life. The implementation of cross-section topics, including the Environmental education, into science classes, is possible through a variety of techniques. One of the least used methods is a real school experiment. The following…

In this research, the laboratory perceptions of pre-service science teachers with different goal orientations in analytical chemistry courses in which an inquiry-based laboratory approach had been adopted were examined in a case study. From the pre-interviews conducted with 37 pre-service science teachers, 3 preservice science teachers with…

The challenges of education in the era of the industrial revolution include disruption 4.0, 21st-century skills, globalization, and global competition. Chemistry is a subject that needs to be developed in order to improve the educational system in the era of disruption. The purpose of this research is to identify and analyze the needs of the…

Teaching and understanding the concepts related to ideal gases and their transformations is relatively uncomplicated. However, for science and engineering students, reaching an understanding of and assimilating the concepts related to real gases and their transformations is a more difficult goal. Backed by their considerable experience teaching…

The themes discussed in this study relate to how students reason about the information encoded in rate constants, which is important for developing a deep understanding of chemical kinetics at the molecular level. This study is part of a larger project centered more generally on students' understanding and use of mathematics in chemical kinetics.…

A pedagogical technique, named the Bridge activity, has been developed to assist students' transition from preclass preparation to in-class learning within a flipped organic chemistry course. Bridge activities form the basis of an initial interactive discussion to activate students' prior knowledge and encourage meaningful learning. This paper…
