This paper discusses the significance of model-based teaching on the topic of ionic and metallic bonding in Year 12 Chemistry in a New Zealand secondary school. Based on the conceptualization of the sub-macro level understanding of the bonding structure and properties of ionic and metallic compounds, models and drawings were used as an effective…

Understanding chemical models can be challenging for many university students studying chemistry. This study analysed students' understanding of molecular structures using the Lewis structure as a model, and examined what hinders their understanding. We conducted pre- and post-tests to analyse students' conceptions and changes in them. The…

The abstractness of the chemistry concept can be understood easily through chemistry learning using multiple representations. This article used the Systematic Literature Review (SLR) method to review eleven articles published from 2012 to 2021 and focused on chemistry learning using various representations. The articles are systematically obtained…

Background: Recently, there is a growing interest in independent learning approaches globally. This is, at least in part, due to an increased demand for so-called "21st century skills" and the potential of independent learning to improve student skills to better prepare them for the future. Purpose: This paper reports a study that…

The primary focus of this education leadership portfolio is to reconstruct lessons on chemical reaction concepts for teachers to use and reach all learners of chemistry in Cecil County Public Schools. As a high school chemistry teacher, I have observed that student enrollment in chemistry is relatively low, and students show little enthusiasm…

The aim of this study is to investigate Emiratii high school students' understandings of stoichiometry, their use of metacognitive strategies, and the influence of students' use of metacognitive strategies on their understandings of stoichiometry. Two instruments were used in this study, the first to measure students' understandings of…

The present study was conducted to investigate the degree of effectiveness of cooperative learning instruction over a traditional approach on 11th grade students' understanding of electrochemistry. The study involved forty-one 11th grade students from two science classes with the same teacher. To determine students' misconceptions concerning…

Presents an account of one teacher's path to realizing the depth of intuitive beliefs about science. Organizes chemistry misconceptions into eight patterns of reasoning that include thinking rules and alternative conceptions. (DDR)

Reports on a study that constructs a Lakatosian teaching strategy that can facilitate conceptual change in students' understanding of chemical equilibrium. Results indicate that the experimental group performed better on tests. Contains 81 references. (DDR)

Reports the relationship between student characteristics and results of a test of misunderstanding administered to 49 suburban high school students enrolled in a New York State Regents Chemistry Class. A multiple regression analysis of data revealed that the best predictors of performance on the posttest misunderstanding test was the pretest score…

Addresses the interface between two scientific disciplines, chemistry and physics, and suggests that learners do not readily integrate their knowledge across such domains. Recommends further research on how demarcations encourage learners. Contains 46 references. (DDR)

Investigates Grade 12 students' understandings of the nature of chemical bonds and the energetics elicited across five familiar chemical reactions following a course of instruction. Discusses the many ways in which students can misconstruct concepts and principles. Contains 63 references. (DDR)

The purpose of this study was to: (1) investigate the relationship between the learning approaches of high school students, their prior knowledge, and their attitudes toward chemistry, and their performance on a misconceptions test; and (2) describe and analyze the differences between the responses of students of different learning approaches on…

Describes four chemical terms that students with well-considered reasons use in a way that is not accepted in chemistry. From 4300-7500 senior high school students completed a series of multiple choice tests while other groups of students participated in discussions about the problem situations. Contains 34 references. (DDR)

The problem-solving difficulties of Nigerian preservice chemistry teachers (n=300) were investigated. The results from written tests and an interview show students were capable of constructing mental representations but not solution plans; had inappropriate approaches and strategies; exhibited structural errors relating to a disregard of given…
