Sample preparation is a key step in most biological experiments, including in the subject of lipidomics. Lipidomics focuses on the study of lipids produced in specific organisms, so samples required in lipidomics experiments are usually solutions of biological lipids. To make sure that the scientific experiments are reliable, lipid samples in a…

One expected outcome of physics instruction is that students develop quantitative reasoning skills, including strategies for evaluating solutions to problems. Examples of well-known "canonical" evaluation strategies include special case analysis, unit analysis, and checking for reasonable numbers. We report on responses from three tasks…

As introductory physics courses increasingly focus on student engagement, the use of Learning Assistants (LAs) has increased. LAs and other instructors need to have sufficient PCK to effectively guide student learning. Our goal was to research LAs observed PCK in the classroom and to develop a set of questions to assess LAs' PCK. Our research…

Assessments that are open-ended and student-centered may be used to encourage formation of networks between prerequisite material and new course content thereby promoting meaningful learning. Creative Exercises (CEs) are assessments that allow multiple correct answers and do not penalize for incorrect statements thereby inspiring creativity. CEs…

Research shows that there are multiple benefits to giving college students oral rather than written exams. However, studies that examine, describe, and differentiate how students view their oral exams were never found in a literature search. The purpose of this study was to use Q methodology [Q] to describe the divergent student views about taking…

Teaching practices used by teachers influence students' achievement of learning outcomes. These practices may be explored from students' perspectives. Because gender may influence students' perceptions of learning environments, this study explored gender differences in students' perceptions of teaching practices employed in their biology…

[This paper is part of the Focused Collection on Instructional labs: Improving traditions and new directions.] In recent years, physics instructional labs have been under considerable research and development. However, there seems to be no shared understanding of how the assessment of instructional labs should be arranged to best serve students'…

Testing is a highly important tool, used ubiquitously in academia, to assess student comprehension and understanding of material. Unfortunately, the emphasis placed on test grades has resulted in a modern epidemic of test-related anxiety, which can have adverse health effects on students. Over time, novel testing strategies have been developed to…

In recent years, single-subject experimental courses have not been able to meet the demands of the comprehensive development of life sciences. This study is based on two fundamental disciplines, molecular biology and metabolomics, with the analysis and intervention of tumor-related genes as the starting point. A comprehensive experimental course…

A structured series of activities has been designed and implemented to promote analysis and data reporting skills for second-year organic chemistry students. Student report sheets were developed to assist students in reporting necessary data for their compounds. A series of rubrics have been utilized by students to promote metacognition and by…

Optimizing the workload of university students is important for their academic performance and student experience. Large perceived workloads are associated with poorer academic performance and lower student satisfaction in university students. In response to student feedback in 2021, we redesigned a second-year undergraduate physiology subject to…

This study explores the integration of socio-humanitarian safety components into the chemistry curriculum for secondary education, emphasizing how contextual and competency-based assessments can enhance the preparedness of future chemistry teachers. Employing a mixed-methods approach, the research evaluates the effectiveness of traditional,…

Problem solving is considered an essential ability for becoming an expert in physics, and individualized feedback on the structure of problem-solving processes is a key component to support students in developing this ability. Problem-solving processes consist of multiple elements whose order forms the sequential structure of these processes.…

This research will analyze the issues encountered by two science teachers implementing Arduino-based robotic coding projects. This research employed a case study design. This research has used a criterion sampling group. This study used semi-structured observation, interviews, and video observations as data collection tools. The teachers conducted…

The purpose of this study was to explore an approach to an elementary science methods course that utilized a science notebook to physically distinguished multiple perspectives of science teaching and learning. We conceptualized teacher candidates' (TCs') thinking within a framework titled "Exploring Multiple Perspectives in the Methods…
