The science curriculum aims to provide students with the identity of a researcher, thinking skills, and scientific process skills. Critical thinking skill emerges as one of the skills that should be emphasized in the teaching process in terms of its structural features and the qualities aimed to be given to individuals. For individuals to gain…

Analogies are bridges between prior knowledge and new knowledge to make meaning of the new one. Analogies are particularly effective in teaching science concepts that are not very apparent in the students' everyday lives due to their abstract nature. For this reason, it is essential to adapt analogies to teach new concepts effectively in science…

One of the central tenets of Universal Design for Learning (UDL) is the presentation of concepts using multiple modalities. As new technologies develop, the variety of available representations increases as well. In this paper, we explore how 3D-printed models can provide another avenue of approach to physics concepts. Students with low vision may…

Science is a systematic study of natural phenomenon. The natural phenomenon is perceived and understood by an individual based on his/her experience and cultural context. The term misconception is complex in nature and has been conceptualize as alternative conceptions, preconceptions, alternative ideas, conceptual stumbling blocks, erroneous…

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…
