Activities and strategies will be discussed that have helped students at the Xavier University of Louisiana, a historically Black and Catholic university, effectively engage in the course and learn organic chemistry in an online synchronous remote mode during the five-week summer session courses (summer 2020 and summer 2021) using video-creations,…

This paper describes the use of a tabletop electron microscope in teaching college level physics. The workings and use of an electron microscope encompass many aspects of science, technology, engineering and mathematics (STEM). A sequence of activities was constructed to compliment the instructional material in the physics course of the University…

Midterm exams are a multi-use tool, providing evaluation of students for professors but also acting as a learning tool for students. Midterms may improve learning outcomes by contributing to the testing effect: the phenomenon in which retrieval of learned material (i.e., testing) produces improvements in long-term retention beyond those produced…

The education of physicists requires annual progress in mathematics through grades K-12, continuing on to high school physics, undergraduate instruction, and often many years of postgraduate study. The traditional domain of physics education research is the study of pedagogical techniques for a single lesson or a single course, but the physics and…

This work address the preconceptions of first year engineering students about the kinematic graphs and the outcomes of a pedagogical strategy that relies on Predict -- Observe -- Explain learning method mediated by a video analysis software. The whole learning procedure was accompanied by a written material as students' worksheets which enabled a…

Integration of active-learning approaches into increased-structure postsecondary classrooms significantly improves student academic outcomes. We describe here two parallel sections of Introductory Biology that shared learning objectives and content but varied in course structure. The large-enrollment traditional course consisted of four 50-minute…

The purpose of this study was to investigate the effect of the case-based learning (CBL) method used in "biochemical oxygen demand (BOD)," which is a topic taught in the environmental chemistry course, at Dokuz Eylul University, on the academic achievement and opinions of students. The research had a quasi-experimental design and the…

A low-cost turbidimeter, colorimeter, and nephelometer (TCN) multipurpose instrument applicable for undergraduate, graduate, and research laboratories is demonstrated within this work. The instrument relies on simple and robust electronics while using a PC sound card as an analog-to-digital converter. The performance of the instrument was…

Creating instructional activities and assessments that align with expected learning outcomes can improve student learning. Communicating learning expectations to students may lead to better student performance and an increase in student perceptions of the fairness of the assessment tools. One tool for communicating learning outcomes is the…

Students' difficulties in quantum mechanics may be the result of unproductive framing rather than a fundamental inability to solve the problems or misconceptions about physics content. Using the theoretical lens of epistemological framing, we applied previously developed frames to seek an underlying structure to the long lists of published…

In this paper, we analyse the conceptual and procedural difficulties that university students of the Primary Education Degree have about respiratory physiology. To carry out this study a questionnaire was designed in order to assess the knowledge of these future teachers before and after studying the first subject of natural sciences of the…

This study investigates the knowledge acquisition of biology and physics freshmen students with special regard to differences between high school (HS) high performing and low performing students. Our study is based on a prior knowledge model, which describes explicit knowledge as a composite of four knowledge types: knowledge of facts, knowledge…

Technological innovation in science provides complementary tools for exploring new teaching strategies within a pedagogical framework that promotes interaction between the teacher and the learner. This work is based on the implementation of a computer application modeling crystallographic material structures, in order to identify and study the…

This study examines scientific practices associated with scientific writing in organic chemistry in China. Although there is rapidly growing literature on the features and strategies of scientific writing, further research in this area is needed to recognize and treat scientific writing as a social endeavor to evaluate it in a more comprehensive…

Team based learning (TBL) is a time tested teaching-learning (T-L) tool involving collaborative learning but has hardly been tested for teaching clinical biochemistry to undergraduate medical students. The present study was designed to (a) compare problem solving skills of first year MBBS students after attending a TBL session on 'organ function…
