This study examined the representational competence and fluency of preservice science teachers (PSTs) enrolled in a science teacher education program. It compared how these skills influence the understanding of the same cohort of PSTs when teaching concepts in chemistry and physics. Utilising a quantitative descriptive comparative design, the…

The study was conducted to ascertain if learning styles and corresponding teaching methods are factors that influence effective learning. The study employed a non-equivalent planned variation quasi-experimental design. The study's sample comprised 362 chemistry students from six senior high schools in Delta State. The students were selected using…

Developing digital materials for learning purposes, or e-learning materials, is not as straightforward as it may seem. The traditional approach is multimedia instruction, the presentation of both pictures and words in an e-learning format to foster learning. However, multimedia instruction, to develop meaningful learning, needs to support the…

The Ouchterlony double immunodiffusion technique is used as a teaching tool for studying immune responses and exemplifying differences in antigen-antibody reactions. Although commonplace in undergraduate labs, standardized commercial kits limit learning experiences because they have fixed modalities of use, a low shelf-life, and impose budgetary…

The aim of this study was to determine the effect of Mobile AR (MAR) supported Flipped Learning Model (FLM) applications on the academic achievement of first year undergraduate students in General Chemistry Laboratory course and to investigate the students' views on MAR supported FLM. In the study carried out with a quasi-experimental design with…

Evaluating students' cognitive understanding of core concepts and identifying learning path aligned with their cognitive developmental patterns are critical for enhancing conceptual mastery in chemistry. This study employed the Rule Space Model to investigate students' cognitive characteristics and learning path in comprehending the conceptual…

Fluorescence experiments hold great potential to develop and deepen student understanding of fundamental chemical concepts because the phenomenon is engaging and also illustrates many different chemical concepts and applications, including in quantum mechanics, spectroscopy, kinetics, equilibrium, and stoichiometry, through easily observable…

Dimensional analysis is an algorithm currently in use in almost every chemistry classroom in the United States. Chemistry educators use this procedural tool in the classroom with the intention of providing students with a reliable method to solve many of the relatively simple math problems they encounter. The unintended consequence of using this…

Teaching engineering students how to effectively communicate using the language, representations, and tools specific to their discipline is important to their development as practitioners in their respective fields. This article describes a literature review of learning activities intended to teach crystal structure and crystallography and…

Recently the trend of words in the world is related to sustainable development such as "green" has become a new trend in everyday human life. This study aimed to analyze and map the chemistry learning with green chemistry insight for undergraduate students of chemistry education program as an effort to conserve the environment as one of…

This study evaluated recent advances in learning progressions for the concept of matter (LPCM) and explored trends by reviewing the literature on the topic published between 2005 and 2021. A total of 21 studies were reviewed. Fifteen studies were devoted to developing LPCM of varying spans and grain sizes. There were six follow-up studies based on…

The study complements previous research on a case study of chemistry lesson plans design and teaching. It has been found that chemistry education in the Gambia has been challenged by ineffective lesson plans design and teaching, and laboratory resources. The consequences have been unsatisfactory learning outcomes. However, what could lead to…

This study investigated the impact of teaching materials developed using the reconceptualized family resemblance approach to the nature of science (RFN) on pre-service chemistry teachers views about the nature of science (NOS). The materials were based on the book "Leviathan and the Air-Pump: Hobbes, Boyle, and the Experimental Life" by…

The ability to express scientific concepts in mathematical terms and integrate scientific and mathematical reasoning about a phenomenon is a foundational cognitive process involved in scientific thinking. This process called "blended math-science sensemaking" (MSS) is a desired skill for all science, technology, engineering, and math…

In this study, it was aimed to examine the effects of inquiry-based activities supported by web 2.0 tools on the attitudes of students towards the chemistry lesson in the unit of 'Acids, Bases and Salts' in the 10th grade chemistry lesson. Considering the relevant achievements in the 2018 chemistry curriculum and using the web 2.0 tools Padlet and…
