Background: Science educators around the world have recognised that difference in performance exists between male and female students in chemistry and there have been several efforts and interventions through research and workshops to bridge this gap. Purpose: Owing to the current growth of the effects of the use of computer simulations on…

The epistemic components of science are included in instruction through the three-dimensional learning of the Next Generation Science Standards (NGSS). Students use the Science & Engineering Practices to engage the Disciplinary Core Ideas through the perspective of the Crosscutting Concepts. The NGSS focus on the epistemic aspects that all…

This study investigated Chemistry students' performance and retention (knowledge and understanding, knowledge and application, perception and attitude) in Organic Chemistry in three Senior High Schools (SHSs) within Tamale Metropolis in Ghana. Collaborative learning models were employed as intervention strategies. Quasi-experimental design was…

Collaborative learning with peers can lead to students learning from each other and solving physics problems correctly not only in situations in which one student knows how to solve the problems but also when none of the students can solve the problems alone. We define the rate of construction as the percentage of groups collaborating on problem…

[This paper is part of the Focused Collection on Instructional labs: Improving traditions and new directions.] In this paper, we describe the results of a research project whose goals were to (1) develop and implement video-based experimental investigations using the Investigative Science Learning Environment (ISLE) approach and (2) study how…

K-8 science teacher candidates often struggle with the difficult learning tasks in multiple science courses in their teacher-training program. One of the major parts of these science courses is biology. Student learning in biology depends on their motivational and affective variables as much as their cognitive abilities. As one of the theories of…

The creative achievements of eminent genius in Chinese history are of enormous interest. There is, however, uncertainty about the accurate measurement of eminence and creativity. The most tenable measurement approach is historiometric. Nearly all historiometric research on eminence and creative achievement has involved Western samples. The present…

The purpose of this mixed-method action research study was to improve Black students' performance in my sixth-grade science class by improving their ability to use the claim, evidence, and reasoning (CER) framework. Using criterion-based convenient sampling, I enlisted 17 Black participants, all of whom were underperforming in my science class at…

Different molecular representations are usually used to depict the three-dimensional (3D) structure of organic compounds. Mastering the skill of interconverting one form into another is essential for students to ensure success in organic chemistry. The traditional and recently developed methods for completing such interconversions that rely on 3D…

An integrated system comprising a commercial high-performance liquid chromatography HPLC (except autosampler) equipped with an external multichannel autofeeding module was developed to accomplish interference-free separation and kinetic tracking for the H[subscript 2]O[subscript 2]-thiourea reaction, which is proposed as a lab experiment for…

Over the past few decades, physics education researchers (PER) developed a variety of assessments instrument for research and instructional purposes. Most of these instruments are designed to measure topical understanding. Generally, if student performance is satisfactory, it is assumed that the students possess the content understanding and that…

This study investigates the relationship between study methods and exam performance in introductory physics courses. Data were collected over 3 years through surveys to examine students' study habits, perceived effectiveness of techniques, and the correlation between time allocation and exam grades. Results indicate that high-achieving students…

The impact of an interactive in-class Valence-Shell Electron-Pair Repulsion (VSEPR) activity, designed and implemented by the author in her first-year undergraduate chemistry classes, was assessed through the statistical analysis of pre- and posttreatment quizzes on VSEPR theory and the analysis of questionnaires. The activity consisted of…

This research is a large study over an extended period of time involving hundreds of general chemistry students and multiple instructors at the US Naval Academy. The purpose was to investigate whether a combination of clicker content and confidence questions would improve the performance and metacognition of students of different achievement…

We applied a balance theory of wisdom to thinking in the domain of science. In two studies, we administered maximum-performance scales measuring Scientific Wisdom, Scientific Reasoning, Scientific Creativity, and fluid and crystallized intelligence, and a typical-performance scale of self-assessed wisdom. Our Scientific Wisdom scale, along with…
