Background: The competencies for the 21st century are defined as a broad and interrelated system of knowledge, skills, values and attitudes enabling the full application of man in personal and professional life. Regarding the science education competencies combining science and scientific knowledge, as well as skills such as inquiry, critical…

The study sought to determine the effects of a pilot home-based science intervention on deaf and typically hearing children's conceptual understanding of science and their abilities to reason about and communicate their understanding (scientific enquiry skills). Data show that by age 5 years a science attainment gap exists between deaf children…

The incorporation of interdisciplinary education, a topic of significant global interest, is increasingly being recognized as a key aspect of educational innovation in Vietnam. This recognition extends to several fields, including STEM (Science, Technology, Engineering, and Mathematics) education. This research aims to design and implement a STEM…

The methodology and mathematical treatment of several classic multivariate methods for the analysis of spectroscopic data is demonstrated in a straightforward way that can be used as a basis for teaching an undergraduate introductory course on chemometric analysis. The multivariate techniques of classical least-squares (CLS), principal component…

Developing models and using mathematics are two key practices in internationally recognized science education standards, such as the Next Generation Science Standards (NGSS). However, students often struggle with these two intersecting practices, particularly when developing mathematical models about scientific phenomena. Formative…

Course-based undergraduate research experiences (CUREs) are being increasingly implemented to broaden the opportunities for undergraduate students to engage in authentic research across STEM disciplines including chemistry. The present review synthesizes the literature on chemistry CUREs, encompassing 68 articles published between 2016 and 2022…

Often overlooked in many molecular cell biology laboratory and cell culture courses, suspension cells represent an important aspect of molecular cell biology and cell culture. Most primary cell cultures and cell lines are adherent cells which grow in monolayers on surfaces. However, other cells such as hematopoietic cells, certain tumor cells, and…

To evaluate the recent advances in learning progression (LP) research and identify future research directions, we reviewed LP literature from 2006 to 2018. Through a systematic search of Web of Science databases and key journals, we located 130 LP articles published between 2006 and 2018. Among these articles, we reviewed 86 studies. The review…

Single-outcome experiments are used in the undergraduate instructional laboratory, particularly for large lectures associated with multiple sections of instructional laboratories, due in large part to efficiencies associated with chemical purchases, experiment preparations, and assessments. Despite the practical advantages, single-outcome…

We constructed a low-cost experimental kit consisting of a compact 532-nm diode laser, optics, and optomechanical components that arrange on a small honeycomb breadboard. The kit is flexible enough to construct five typical wave optic experiments, e.g., double-slit interference, Michelson and Mach-Zehnder interferometers, diffraction, and Malus's…

Before students learn Kirchhoff's rules, they are typically taught how to solve "combined series-parallel" circuits. The method presented in many textbooks begins by drawing a series of simplified circuits, replacing series and/or parallel elements with their equivalent resistances, eventually reducing the circuit to a voltage source and…

This study explores how life science researchers conceptualize, operationalize, and value Interdisciplinary Research (IDR). We interviewed a sample of 10 established life science faculty to understand the researchers' lived experiences and perspectives on participating in IDR. Six themes emerged from our data: (1) IDR requires the integration of…

Studies indicate that the failure of science education to meet the needs of the 21st century is to some extent due to the inability to incorporate scientific reasoning and higher order assessments in the school instruction. Though the outcomes of education seek higher-order thinking abilities there is a lack of high ability assessments in…

Rapid developments in educational technology show its impacts on classes. One of the recent trends in science education is virtual laboratory environments. The goal of this study is to reveal the effects of inquiry-based hands-on and virtual laboratory environments on pre-service science teachers' inquiry skills. A quasi-experimental research…

Conceptually understanding chemistry requires the ability to transition among representational levels to use an understanding of submicroscopic entities and properties to explain macroscopic phenomena. Past literature describes student struggles with these transitions but provides limited information about upper-level post-secondary chemistry…
