A lab appropriate to introduce voltammetric techniques and basic electrochemical parameters is described in this work. It is suitable to study theoretical concepts of electrochemistry in an applied way for analytical undergraduate courses. Two electroactive species, hexaammineruthenium and dopamine, are used as simple redox systems. Screen-printed…

An experiment for teaching mixing intensification in reaction engineering is described. For this, a simple tubular reactor was constructed; helical static mixer elements were fabricated from stainless steel strips and inserted into the reactor. With and without the internals, the equipment operates as a static mixer reactor or a laminar flow…

Coursework that is dependent on experiential learning, such as that offered in the laboratory-based sciences, can present barriers for a variety of students. These barriers can be magnified for students who experience disabilities that impact their access to the full depth of the course content and materials. Our unique perspective was formed…

Due to the necessity to continue learning even during the pandemic, schools opened utilizing distance learning modalities. However, there is a dearth of evidence on the effectivity of this modalities in physics. In this study, we investigated the effects of three physics distance learning modes; the module-only (MO), virtual lab plus module (VLM),…

This study captures student perceptions of the effectiveness of remote learning and assessment in two associated engineering disciplines, mechanical and industrial, during the COVID-19 pandemic in a cross-national study. A structured questionnaire with 24 items on a 5-point Likert scale was used. Parallel and exploratory factor analyses identified…

Protocol-guided teaching is a student-centered instructional model in which the teacher creates the learning protocol prior to the lesson in order to direct students toward active and autonomous learning. A well-structured learning protocol is essential for the effective application of this instructional paradigm. This article evaluates the…

Integrating authentic research practices into introductory laboratory courses to prepare tomorrow's scientists has become increasingly prevalent over the past decade. However, an incomplete understanding of the nature of science (NOS) and authentic scientific inquiry (SI) precludes higher-level learning in undergraduate research experiences. In…

Background: Although sound is an everyday phenomenon that we hear about constantly, numerous studies have reported that students often exhibit learning difficulties in understanding this subject. Only a few studies have proposed programs involving practical learning experiments to provide students with solid conceptual knowledge. Moreover, little…

Laboratory courses can serve as important avenues to equitably support introductory biology students to develop foundational scientific literacy skills while experiencing the authentic research process. We present a model for an equity-focused redesign of an introductory organismal biology laboratory course at a teaching institution with limited…

As we pass the third anniversary of the World Health Organization's declaration of the SARS-CoV-2 global pandemic, it is beneficial to reflect upon how physiology education adapted to the challenges of the pandemic. At the initial stages of the pandemic, many educators were faced with the challenge of quickly transitioning to emergency remote…

Understanding measurement uncertainty is crucial in experimental physics, as it enables accurate and reliable measurements, facilitates comparison between measurements, and aids in designing experiments. Consequently, measurement uncertainty has emerged as a critical learning goal for many introductory physics labs. Here, we explore the impact of…

This study determined the influence of the competency of teachers and the laboratory environment in an online setting on the students' science process skills using mixed methods approach-convergent design. Participants of the study were 2nd year students from different Higher Education Institutions in Region XI, Philippines. Further, to gather…

[This paper is part of the Focused Collection on Instructional labs: Improving traditions and new directions.] National organizations set goals of engaging students in experimentation and authentic scientific reasoning while developing normative concepts to help them develop essential skills and competencies necessary to succeed in our rapidly…

Approaches toward engaging undergraduates in scientific research have included research experiences based in faculty laboratories (FLREs), course-based undergraduate research experiences (CUREs), and courses rooted in primary research literature that may be precursors to research experiences. We examined outcomes for undergraduate biology students…

Despite an extensive amount of research examining students' perceptions of alternative laboratory experiences, little focus has been aimed at the perceptions of adult learners. This two-phase mixed-methods study investigated the preferred at-home laboratory experience, and the factors that played a significant role in the user experiences, of…
