Learning science in the context of local phenomena and problems can be powerful for young people. Yet, designing place-based instructional materials is resource intensive, limiting broad access. This study investigates how instructional materials designed for widespread use can support teacher localization through phenomenon adaptation, whereby…

Dimensional analysis is an algorithm currently in use in almost every chemistry classroom in the United States. Chemistry educators use this procedural tool in the classroom with the intention of providing students with a reliable method to solve many of the relatively simple math problems they encounter. The unintended consequence of using this…

Introductory mechanics is an obligatory course for many disciplines outside of physics and the failure rate is often high. Even the students who pass the course often fail to achieve the main learning goal: The conceptual knowledge required for modeling situations with physics principles. In many cases, this is due to inefficient learning…

Purpose: This study aims to assess the validity and reliability of the Psycho-B'GREAT Module developed according to the ASSURE's Module Development Model. Method: The content validity of the Psycho-B'GREAT Module was assessed by ten experts in the fields related in teaching and learning (T&L) and biology education. In testing the…

This book provides teachers with 50 dynamic activities to teach science, through music, food, games, literature, community, environment, and everyday objects. The authors share tried and tested ideas from their collective 75 years of teaching experiences. For the busy teacher with little time to plan lessons, resources are provided that include…

This study evaluated recent advances in learning progressions for the concept of matter (LPCM) and explored trends by reviewing the literature on the topic published between 2005 and 2021. A total of 21 studies were reviewed. Fifteen studies were devoted to developing LPCM of varying spans and grain sizes. There were six follow-up studies based on…

Idealizations are omnipresent in science. However, to date, science education research has paid surprisingly little attention to the use of idealizations in fostering students' model competence and understanding of the nature of science (NOS). The starting point for the theoretical reflection in this paper is that insufficient consideration of…

In collaboration with educators and researchers, we created an online resource called Phase Separation 101 to help undergraduate students understand the basics of liquid-liquid phase separation, an emerging and complex concept in cell biology for which visual resources are still scarce. This work presents the workflow and visual communication…

Evolutionary medicine is a growing area of research and practice; however, it is not widely discussed in introductory biology courses. Because of the interest in human biology, using evolutionary medicine is a great way to hold students' interest, placing topics in context, making the subject of evolution relevant. Too often students lose interest…

All in-class teaching in the Republic of Trinidad and Tobago, West Indies was suspended on Friday, 13 March 2020, because of the COVID-19 global health crisis. These restrictions remained for the commencement of the new academic year 2020-2021, which began in September 2020, thus jeopardizing the delivery of course content at the University of the…

Metacognition and critical thinking have become essential variables in science teaching. However, the low level of metacognition and critical thinking of students at various levels of education in Indonesia is still widely reported. Therefore, to minimize the gap that occurs, an instructional model is needed as an alternative solution, namely the…

Despite its crucial importance in physics, there are not many studies focusing on student difficulties and teaching strategies related to the (1D) wave equation in the PER literature. In order to contribute to fill this gap, we conducted a study with university students which focused on specific aspects that are crucial for understanding this…

In view of the mounting requirements for courses in nuclear chemistry and radiochemistry, hands-on experience in the separations of radioisotopes is imperative. Three separation techniques commonly used were introduced, coprecipitation, liquid-liquid extraction, and ion-exchange chromatography. Their principles and the associated fundamental…

In chemistry, a eutectic mixture refers to a mixture of two or more components at which the lowest possible freezing point is observed. This phenomenon is covered in a wide range of curricula such as physics, chemistry, chemical engineering, and pharmacy to various depths. Despite the significance of this phenomenon in pharmaceutical compounding…

The COVID-19 pandemic has displayed new challenges for chemistry instructors and students worldwide. An essential part of learning chemistry involves interactions in a laboratory ambiance. However, nowadays, it is necessary to consider alternatives to teaching experimental chemistry in an online environment. As a course project proposal, the…
