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…

This synthesis of ethyl 6-acetoxyhexanoate (Berryflor) is designed as an experiment for use in a second-year organic chemistry course focusing on the synthesis and reaction of esters. The compound is described as having a raspberry-like odor with jasmine and anise aspects. A two-step procedure for its synthesis beginning with inexpensive…

We report here the development of an inexpensive and engaging laboratory-based activity that can help students learn about the scientific method and the role of plant epicuticular waxes and surfactant function on waxy plant leaves as real life example in the agricultural industry. Three each of nontreated collard leaves ("Brassica…

This research aims to develop an instructional model using advanced laboratory equipment (ALE) based on collective intelligence attributes that can be applied to the scientifically-gifted students. The developed GI-ALE model is defined by introducing the principles of the group investigation (GI) model to the existing ALE instructional model based…

This article is a brief account of how the Writing Center at Daytona State College has begun to utilize social media in our space. We examine the platforms that we use, along with the data associated with them, and then discuss our goals for integrating our staff into the narrative that we share on campus and virtual campus. We first want to see…

Often overlooked in many molecular cell biology laboratory and cell culture courses, suspension cells represent an important aspect of molecular cell biology and cell culture. Most primary cell cultures and cell lines are adherent cells which grow in monolayers on surfaces. However, other cells such as hematopoietic cells, certain tumor cells, and…
