Argumentation and modelling are core scientific practices, and studies suggest that incorporating the specific practices in the teaching of science can engage learners. This is a qualitative study of a classroom of 10-12-year-old students working collaboratively in argumentation and modelling. The aim of the study was to explore how primary school…

Over the past several years, we have contributed several articles to "TPT" that focused on a forensics-style reexamination of historical events. In each article, we presented a case study as a pedagogy for teaching topics from introductory-level physics courses. Recently, we assembled our prior work into a series of…

A simple one-dimensional [superscript 1]H NMR experiment that quantifies protein bound to gold nanoparticles has been developed for upper-division biochemistry and physical chemistry students. This laboratory experiment teaches the basics of NMR techniques, which is a highly effective tool in protein studies and supports students to understand the…

The non-major's two-semester organic chemistry course at UPR-RP aims at developing a more integrated and meaningful understanding of the fundamentals of Organic Chemistry. To achieve this goal, we have implemented a novel instructional design that focuses on nine terminal objectives. The nine terminal objectives describe what students should be…

A comprehensive experiment for third-year undergraduate students in pharmaceutical engineering is described. Students had previously completed courses in analytical chemistry, chemistry of natural products, and bioseparation engineering and had background knowledge in purification, quantitative analysis, packed column chromatography,…

Infrared (IR) thermography renders invisible infrared radiation with intuitive coloration in images and videos taken of objects, reactions, and processes. Educators can take advantage of this technology to extend students' sensory perception of chemical reactions or processes that absorb or release heat in rich detail. In theory, IR thermography…

The main purpose of this research is to determine the effect of the volume of concept on the level of understanding the relationship between concepts. The mixed method was used in the research. Volume of concept form, concept map form and puzzle scales were used to collect quantitative data. Qualitative data was collected through a fully…

This paper is about "augmented reality" (AR) and its potentials to support students in handling scientific representations. For this purpose, first representations are examined from a science educational and instructional psychology perspective. After giving a short overview of AR in general and how it can be delineated from…

Instructors expect students to read before class to engage them in using higher-order thinking skills that are critical to performing in group work and engaging in discussions. As many instructors are aware, however, for various reasons many students don't read the assigned textbook. In this study, science news articles were used as prereadings to…

Texts presenting novel statistics can shift learners attitudes and conceptions about controversial science topics. However, not a lot is known about the mechanisms underlying this conceptual change. The purpose of this study was to investigate two potential mechanisms that underlie learning from novel statistics: numerical estimation skills and…

Feature engineering, the construction of contextual and relevant features from system log data, is a crucial component of developing robust and interpretable models in educational data mining contexts. The practice of feature engineering depends on domain experts and system developers working in tandem in order to creatively identify actions and…

Teachers across the United States and worldwide found themselves in unprecedented educational situations during the early response period to the COVID-19 pandemic in spring of 2020. Efforts to quarantine and provide social distancing to prevent the spread of the disease brought mandated school closures throughout the United States, and teachers…

Effectively mastering organic chemistry means having the ability to recognize structural patterns, identify properties or behaviors as a result of patterns, manipulate and transform representations, and predict future outcomes. Often students rely on rote memorization of seemingly disconnected information instead of developing a sound…

The dissertation is composed of two sections. The first section is composed of chapters one, two, and three and describes the study of macrocyclic [beta]-hairpin peptides derived from [beta]-sheet peptides. The second section is composed of chapters four and five and discusses the curricular innovations made to support the remote instruction of an…

To address the need for physics courses that stimulate non- STEM majors' interest in, and appreciation of, science, the Department of Applied Physics has developed a popular course for Yale College undergraduates, The Technological World, that explains the physics behind technologies that students use every day. The course provides an in-depth…
