In learning during the current epidemic, students cannot meet face to face on campus, and learning geometry in universities is a dreadful lesson before the pandemic. Both at UPGRIS and other private universities so far, students are required to use a compass and ruler in making flat shapes and building spaces so they have to face to face with the…

This study is a follow-up to one on the pass rates of basic writers in a large, urban Midwestern university. Students who came for eight or more mandatory writing center tutorials for their basic writing course passed at a rate of 90% or higher each semester from 2013-2016. The current study examined their graduation rates. These students…

The purpose of this study was to explore how teachers at a southwestern secondary private charter school utilize the on-campus fabrication lab to promote the implementation of problem-based learning (PBL). Guided by the theory of constructivism, I qualitatively explored the processes teachers engage in when implementing a PBL lesson using a…

[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'…

Background: Experiential learning is commonly used in postsecondary settings, especially in undergraduate, agricultural, and laboratory courses. However, a lack of attention has been paid by educators to critical components of experiential learning. Purpose: The effects of reflection mode (peer-verbal or written journal reflection) and transfer…

The blog and distance learning: the former can enhance, enlighten, and elevate the educational experience for the student and the teaching experience for the instructor. And blogs are especially suited for the asynchronous environment where nearly everything is written and remains throughout the course, so students can continually refer to the…

Animal models are widely used in laboratory practicals in biomedical disciplines. However, experiments involving animal work are usually time-and-labor consuming. It is also costly to run an animal lab and the animal caring/holding request special training. Here we present a laboratory course design that provides students with wet lab experience…

This paper addresses the fundamentals, structuring, and application of a Formative Dimensions for Green and Sustainable Chemical Education (Formative Dimensions -- GSCE) qualitative evaluation tool of experimental processes. This instrument was created considering the need to resignify laboratory practices in Chemical Education. Qualitative…

ChatGPT is a brand new, free AI chatbot that has the potential to produce a seismic shift in chemistry education, especially in written lab reports. An example is explored in which ChatGPT is used to write the discussion portion of a lab report. Ways to detect the use of ChatGPT are also discussed.

Recently, smart sensing/actuation paper has attracted significant interest due to its potential usage as a sustainable component in future electronics, robotics, and intelligent sensing devices. In acknowledging the importance of this topic for the engagement of students at the university level in conjunction with Industrial Revolution 4.0, it is…

Antioxidants are molecules that act against free radicals, and this effect can bring many benefits to health and society. Antioxidants can be found in various matrices of nature, such as fruits and plants. Some studies have shown that "Rhizophora mangle," a typical mangrove plant, is rich in antioxidants. People report its use for…

Pulsed field gradient nuclear magnetic resonance (NMR) is used to estimate the size of quantum dots (QDs) produced in a simple, fast, small-scale synthesis. This upper-division laboratory experiment teaches the basics of QD synthesis and pulsed field gradient NMR, a powerful technique for measuring diffusion coefficients in solution. The diffusion…

There is an increasing need for fundamental electrochemistry concepts to be taught in the undergraduate curriculum, given the broad applicability of electrochemical technologies in addressing a wide range of global issues from critical energy shortages to real-time medical diagnostics. However, many electrochemical concepts are often taught in…

Course-Based Undergraduate Research Experiences (CUREs) have become more commonly incorporated in laboratory courses in undergraduate education. Because CUREs incorporate research within the context of a course, the benefits of mentored research (self-efficacy, science identity, persistence, and more) are extended to each student enrolled. CUREs…

A multistep synthesis of a metal-free organic dye-sensitizer for solar cells was developed as a multifaceted research project for upper-division undergraduate students with a goal of introducing students to the application of organic synthesis in material science, and renewable energy research. The characterization of the dye is done by thin-layer…
