Chemistry includes observable phenomena and materials related to daily life, but learners sometimes have difficulties understanding the theoretical and abstract nature of chemistry as well as its applications and relating it to everyday experiences. In this manner, the aim of the study is to determine and assess whether pre-service science and…

The high turnover rates of science educators in high-need secondary schools are a concern for many educational leaders. There is a gap in the literature for understanding the coaching strategies and practices that are perceived as being beneficial for science instructional coaching of novice science teachers in high-need secondary schools. In this…

This study examines the instructional decision making of an eighth-grade general education science teacher working with Culturally and Linguistically Diverse (CLD) students in a heterogeneously grouped class without the support of a specialized English to Speakers of other Languages (ESOL) teacher. To do so, this study employs Erving Goffman's…

Given the role of scientific argumentation in science education (Osborne, 2010), argumentative discourse styles provide a means to understand the various dialogue types with distinct rhetorical features that individuals adopt during argumentative activities. Previous research indicates that different argumentative discourse styles lead to varied…

This is a qualitative, descriptive, and multi-case study, in which the researcher investigated the perceptions of middle school teachers who were implementing three-dimensional learning aligned with the Next Generation Science Standards (NGSS) into their instructional practices. The participants were 10 middle school teachers who worked in three…

The area of interest considered for the study was the overall academic achievement in biology lecture and laboratory courses using Bloom's Taxonomy. The problem of the study is the lack of higher-order thinking skills leading to a learning gap in many universities and colleges. The purpose of the quantitative correlational study was to determine…

Global climate change (GCC) presents unprecedented global concerns, notably food supply limitations, unsustainable use of natural resources, and widespread environmental degradation. The International Panel on Climate Change (IPCC) reports a 0.85 °C increase in global average temperatures between 1880 and 2018 and a 50% increase in global carbon…

A student experiment that uses QuEChERS (quick, easy, cheap, effective, rugged, and safe) methodology for extraction and HPLC for quantitative determination of tocopherols from seeds and nuts is described here. Chromatographic separation is achieved by using a pentafluorophenyl stationary phase which gives enhanced separation of the tocopherols…

Dynamic biochemical processes are often difficult for students to grasp in the classroom using static images or models, or even through watching simulation videos. This is particularly true for protein-folding and enzyme catalysis, two key biochemistry concepts. The author has developed and tested two 3D, dynamic, and interactive classroom models,…

This study described the implementation procedure (step-by-step) of the culturo-techno-contextual approach (CTCA) in the classroom with concrete curricular examples for each step. The study then proceeded to explore the potency of CTCA on nuclear chemistry, a traditionally perceived difficult concept among secondary school students in Nigeria, as…

The laboratory experiment presented here describes the use of a calcium ion-selective electrode (Ca-ISE) to determine the concentration of zinc in a supplement tablet. This approach was developed to show students how to expand the range of applications of Ca-ISE to enable the determination of metal ions other than Ca[superscript 2+]. To determine…

Infrared (IR) spectroscopy and catalysis represent two of the most practically relevant topics in chemistry, but they are normally taught in separate contexts at the undergraduate level. Although IR spectroscopy is introduced to students as a tool for organic compound characterization, it also finds wide applicability in the investigation of…

Laboratory safety has received heightened attention due to a series of devastatingly tragic accidents in both academic and nonacademic settings. Consequently, chemistry departments at various academic institutions now offer some form of formal training in laboratory safety for entering graduate students. Although the extent of this training varies…

The inclusion of the InChI or SMILES codes as a one-sentence answer allows web-based classroom response systems to provide instant feedback to some of the most typical drawing-based questions asked in organic chemistry courses. This paper discusses the implementation and scope of this strategy using smartphones as the only hardware requirement.

Second-semester biochemistry students at two primarily undergraduate institutions, the California State Polytechnic University, Pomona, and the State University of New York College at Cortland, worked on a collaborative, semester-long project that resulted in the production of bioinfographics focused on metabolic pathways. Students were divided…
