The study that is the subject of this paper tested the effects of EDI (explanation-driven inquiry) on students' redox conceptual understanding and their misconceptions. Two classes of 119 10th grade high school students were involved. Two groups of students in the same school were chosen. One class that was taught by EDI teaching was set as the…

The effectiveness of blended learning was evaluated through the integration of an online chemistry platform, LabLessons. Two modules, "Formation of Hydrogen" and "Titration," were designed by college mentors alongside classroom chemistry teachers to engage and allow high school students to better comprehend these scientific…

Success for students majoring in STEM (science, technology, engineering, and mathematics) within undergraduate chemistry courses is crucial for retention in science degree programs, especially for students perceived as lacking content knowledge and skills. This study leveraged blended learning structures in a remedial chemistry course combined…

This study investigated 27 chemistry professors' perceptions of learning in undergraduate education and their suggestions for adopting an inquiry-based pedagogical approach to teaching and learning. Semistructured interviews revealed that two thirds of participants perceived undergraduate learning in traditional ways such as the acquisition of…

Temporal analyses are critical to understanding learning processes, yet understudied in education research. Data from different sources are often collected at different grain sizes, which are difficult to integrate. Making sense of data at many levels of analysis, including the most detailed levels, is highly time-consuming. In this paper, we…

One focus of 21st century science education is teaching students authentic disciplinary practices. Scientific argumentation is one such practice, and evidence suggests it is not only a key skill, but also a facilitator of high-level comprehension. Science teachers need assistance teaching and incorporating argumentation into their work. In this…

In the wake of increasing evidence that students' positive attitudes towards science particularly in chemistry and physics change strikingly as they move up in school, this study explores student perception of intrinsic and extrinsic factors that make them feel cognitive load in learning physics, chemistry and biology resulting in difficulty to…

This article describes how to construct a simple, inexpensive, and robust colorimeter from a few Lego bricks, in which one light-emitting diode (LED) is used as a light source and a second LED as a light detector. The colorimeter is suited to various grades and curricula.

Chromatographic instrumentation has been really influential in shaping the modern chemical practice, and yet it has been largely overlooked by history of science.Gas chromatography in the 1960s was considered the analytical technique closer to becoming dominant, and being the first automated chromatography set the standards that all the subsequent…

The aim of this study is to compare 2018 Science Course Curriculum (SCC), 2015 Trends in International Mathematics and Science Study (TIMSS) and 2018 High School Entrance Examination (HSE) in terms of content domains, cognitive domains and learning objectives. Qualitative research method, was used in this study. Data were analyzed using document…

Connecting the behavior of invisible (to the naked eye) particles governed by the principles of quantum mechanics to the world we can see and touch requires a host of inferences, almost none of which can be extrapolated from experience. Molecular-level sensemaking thus relies upon intellectual resources that must be developed in large part by…

The study sought to determine the relationship between problem-solving skills and measure of working memory and attention span of science students of low ability level. The study adopted correlational survey research design. The population for the study comprised all Secondary School I (SSI) that offered physics, chemistry and biology as school…

The following report addresses the impact of preparatory education on first year science grades at two Ontario-based universities. Specifically, the impact of high school and university level preparatory courses on their respective first year university grades will be addressed. A variety of analytic and visualization-based strategies will be…

This research aimed at describing the effectiveness of the macromedia flash based inquiry learning in improving students' concept understanding in chemistry learning. It was an experimental research with post-test only design. The population was the eleventh-grade science students of state high school 5 Yogyakarta, Indonesia. The sample in this…

The Spring 2020 semester will be marked in our history as one of the most challenging semesters for higher education, although through the adversity, we were presented with opportunities for classroom innovation. A reflective account of the teaching insights gained from implementing a COVID-19 miniunit and utilizing remote oral examinations is…
