We describe a scaffolded assessment activity that introduces students to the essential theories and principles of chromatography. This summative assessment was redesigned to introduce scaffolded and "fill-in-the-blank" questions about the chromatographic separation of mixtures. In addition to analyzing chromatograms and interpreting…

Reading and understanding scientific literature is an essential skill for any scientist to learn. While students' scientific literacy can be improved by reading research articles, an article's technical language and structure can hinder students' understanding of the scientific material. Furthermore, many students struggle with interpreting graphs…

Even though scientific communication and collaboration play critical roles in academic success, they often come in second to teaching laboratory fundamentals. COVID-19 associated capacity constraints forced our program to reexamine the traditional laboratory instruction paradigm by limiting physical attendance, as well as laboratory duration.…

This paper explores the practice of ungrading, a movement embraced by a growing number of teachers and professors who see the process of grading as disconnected and sometimes counter to the learning goals they have for their students. We discuss the limitations of traditional grading systems in the United States, mainly in the way that grading is…

Higher education constantly has to adapt to meet the changing needs of our students. One of the challenges instructors have faced when delivering online courses is the assessment integrity. This issue was highlighted during the COVID-19 pandemic, which forced educators to quickly convert traditional in-person courses to online versions of the…

The purpose of this study was to determine teacher perspectives on emergency remote teaching conducted during the COVID-19 pandemic in science and art centers. The study was carried out using a phenomenological qualitative research design with 41 science and art center teachers from 17 different majors. A content analysis method was employed in…

The use of game in education has been evidenced to improve students' engagement in learning. However, much research shows that the use of game in learning is only effective for high school students, while its use for students of higher education is limited. Research on game in education has predominantly been occupied by Kahoot! while Quizizz has…

People with disabilities rely on a range of accessible technologies to interface with the digital world. However, their needs are often not considered when developing applications in introductory computer sciences courses. These courses traditionally focus on teaching technical skills that do not include those for designing and developing…

This study extends current research by organizing information about students' expectancy-value achievement motivation, in a way that helps parents and teachers identify specific entry points to encourage and support students' science aspirations. This study uses latent class analysis to describe underlying differences in ability beliefs, task…

This study investigates the effects of problem-based learning (PBL) on students' academic achievements in studying "Electrochemistry" within a course on Analytical Chemistry. The research was of a pretest-posttest control group quasi-experimental design and it was conducted with second year students in the Chemistry Teaching Program at…

The purpose of this study was to explore (a) to what extent male and female science teachers pose different types of questions and (b) if the type of science question posed influences the extent to which boys or girls respond to them. Transcripts of the teacher-student interaction in a whole-class situation were analysed, with attention paid to…

Black girls represent a unique subpopulation of science learners. Black girls are unique because they consistently outperform Black boys in science. Despite this trend, Black girls often face dual marginalization in STEM classrooms and professions. Racial and gender marginalization can inhibit the success of Black girls in science if researchers,…

The Periodic Table of Elements is central to the study of modern Physics and Chemistry. It is however, considered by teachers as difficult to teach. This paper reports on a case study exploring reflections on teaching periodic table concepts in five secondary schools from South Africa. Qualitative methodology of interviews and document analysis…

This study aims to describe the history of interdisciplinary education and the current trends and to elucidate the conceptual framework and values that support interdisciplinary science teaching. Many science educators have perceived the necessity for a crucial paradigm shift towards interdisciplinary learning as shown in science standards.…

Chemistry lesson should be supported with experiments to understand the lecture effectively. For safety laboratory environment and to prevent laboratory accidents; chemical substances' properties, working principles for chemical substances' usage should be learnt. Aim of the present study was to analyze the effect of experiments which depend on…
