A significant amount of energy in the form of heat is lost in industrial processes once it is used in specific processes. Among different technologies, high-temperature heat pumps (HTHP) are a valuable method of recovering low-temperature waste heat in the industry in a very efficient way that can be activated using clean electricity. As a…

Learning spaces, the practices in which people engage, and the representations they use are ideological. Ideologies are coherent constellations of values, beliefs, and practices that impose order on how disciplines like engineering operate. Historically, engineering spaces have been dominated by a relatively technocratic, rationalistic, and…

This study investigated the influence of acquired L1 writing skills on exophonic writings of students (N = 147) from diverse majors, who visited an English writing center for assistance. Affective differences revealed students with L1 writing tutelage (WL1) had lower avoidance behavior and higher extrinsic motivation and writing self-efficacy.…

Instructional physics labs offer students unique opportunities to develop an understanding of experimentation. By transforming labs to be more open ended and experimentation focused, instructors can better support student agency and choice. In this study, we examine students' overall sense of and perceptions about agency in two…

Context: Uncontrolled hemorrhage is a major cause of preventable death. Wound care and managing external hemorrhage are important skills for athletic trainers. Objective: Describe a laboratory activity used to allow students to practice managing uncontrolled external hemorrhage and wound packing. Background: The prevalence of active shooter and…

Many scholars experience a number of troubles and difficulties in writing for publication processes. The continuous support and help given in writing centers may provide solutions for international scholars in terms of their academic publication problems. This study aimed to investigate the effectiveness of a writing center with regard to meeting…

In order to provide undergraduate students with a full, rich online learning experience we adapted pre-existing online content including graduate courses from Johns Hopkins University Engineering for Professionals (JHU EP) program. These online courses were designed using published methodologies and held to a high level of rigor of a Masters-level…

Purpose: The purpose of the mixed methods study is twofold. The quantitative portion examined teacher candidates' perceptions of whether they received high-quality early childhood teacher education and support. Specifically, it compared those students who had access to a community college lab school to those students who did not have access to a…

This qualitative grounded theory study applies Discourse Analysis (DA) to focus on the student-to-student (SS) "productive conversation" occurring within groups engaged in several activities in a physical science laboratory with a goal to identify aspects and patterns of such conversation. In this study, Student-to-Student Productive…

The potential for humans to influence Earth's climate was theorized by scientists like Svante Arrhenius as early as 1896. Yet, as late as 2020, political leaders, like the former President Donald Trump, and the people who follow them continue to doubt the possibility. With growing scientific evidence that human activities are degrading our…

An experiment for an undergraduate organic chemistry class based on the application of an ionic liquid as solvent and catalyst of an organic reaction is reported. The whole experiment requires three 3-h lab sessions. First, students prepare the ionic liquid dimethylimidazolium methylsulfate, which is then used as a recyclable catalyst/reaction…

A laboratory experiment was developed to investigate the rheological properties of a green calcium-cross-linked alginate gel as an alternative to the traditional borax-cross-linked poly(vinyl alcohol) gel. As borax is suspected of damaging fertility and the unborn child, a safe, green alternative is necessary. The rheological properties of a…

We demonstrate here a novel laboratory experiment for the synthesis of gold nanoparticles (AuNPs) by using a low energy gold-sputtering method together with a modern, green, and biofriendly deep eutectic solvent (DES). The strategy is straightforward, economical, ecofriendly, rapid, and clean. It yields uniform AuNPs of 5 nm in diameter with high…

This paper reports an experimental activity where students have to carefully analyze the evidence collected at the crime scene, namely fibers and lipstick traces. The fibers are analyzed by infrared spectroscopy, solubility tests, and optical microscopy, while in turn the lipstick traces are investigated by thin layer chromatography. Students also…

National legislation concerning soil pollution by heavy metals in different countries is mostly based on the total heavy metal concentration levels allowed in different soils. As soil pollution is an issue of worldwide concern, here we develop a laboratory exercise for students in which they must check the suitability of a total metal…
