A physical organic chemistry experiment is described for second-year college students. Students performed nucleophilic aromatic substitution (NAS) reactions on 5,10,15,20-tetrakis(2,3,4,5,6-pentafluorophenyl)porphyrin (TPPF[subscript 20]) using three different nucleophiles. Substitution occurs preferentially at the 4-position ("para")…

Practical work is an essential component of science education. However, insufficient approaches towards practical work can limit the potential it has for promoting both students' motivation and situational interest. One suggestion to solve this problem is to use alternative forms of lab instruction which are both motivating and easy to comprehend.…

In the Spring 2017 semester, an instructional designer, a writing center coordinator, and a director of distance library services initiated a pilot project for a seven-campus, eight-satellite center, public university system to cross-train virtual writing tutors in baseline research skills. This case study describes the collaborative pilot…

iSchlenk, a portable instructional cart with equipment for hands-on student experience in safe handling of air-sensitive, moisture-sensitive, toxic, pyrophoric, and/or radioactive chemical materials, is described. The cart, for use by =4 students, has compressed air and vacuum from a diaphragm vacuum pump supplied to 4 three-port Schlenk lines…

Faculty participants in a fellowship designed to engage students at an urban commuter college of technology in their general education curriculum evaluated and redesigned their courses to include place-based learning (PBL) using the Living Laboratory model of pedagogy. Focused on faculty perception of the relationship between PBL and its influence…

Peer instruction has been used extensively in lecture courses; however, there is little evidence of its use in laboratory courses. The purpose of the present study was to describe the implementation of the peer instruction method in a physiology laboratory course in China. Second-year medical students attended a 6-wk physiology laboratory course…

As social and postmodern ontologies continue to shape our definition of space, undergraduate instructors have struggled to incorporate these paradigms in the geography classroom. Recent research suggests that practical applications using field work, qualitative research, and geographic information science can augment students' understanding of…

The current study compared the effectiveness of two methods in biology teaching that are based on the science-as-inquiry approach: visits to authentic university laboratories (AULs) and analyzing adapted primary literature (APL). The methods' effectiveness was measured in terms of high-school students' increased understanding following a 6-week…

While evidence supports the use of cadavers to facilitate the teaching and learning of human anatomy, cadaver-based teaching may not be present at the undergraduate level at many institutions due to limited laboratory access, financial constraints, and the lack of qualified faculty trained to teach in this type of setting. The following case…

An educational researcher sought to collaborate with a classroom instructor to introduce problem-based learning as a new teaching intervention. First, a classroom instructor was approached to consider how a problem-based learning instructional approach might fit with their existing curriculum plan. The researcher and the classroom teacher used a…

The aim of the research is to assess the effectiveness of Virtual Lab (experimental group) compared to Physical Lab (control group) in the level of Science Process Skill mastery of topic salt experiment. This research also was done to compare the students' level of Science Process Skill mastery by gender and to find interaction effect between…

Agricultural mechanics laboratory management skills are essential for school-based agriculture teachers who instruct students in an agricultural mechanics laboratory (Bear & Hoerner, 1986). McKim and Saucier (2011) suggested the frequency and severity of accidents that occur in these laboratories can be reduced when these facilities are…

Providing a project-based experience in an undergraduate biochemistry laboratory class can be complex with large class sizes and limited resources. We have designed a 6-week curriculum during which students purify and characterize the enzymes invertase and phosphatase from bakers yeast. Purification is performed in two stages via ethanol…

In this paper of I have reviewed the test done for validating the special theory of relativity using masers and lasers in last one century. Michelson-Morley did the first experimental verification for the isotropy of space for the propagation of light in 1887. It has an accuracy of 1/100th of a fringe shift. The predicted fringe shift on the basis…

We describe a laboratory experiment that employs the Nanoceria Reducing Antioxidant Capacity (or NanoCerac) Assay to introduce students to portable nanoparticle-based paper sensors for rapid analysis and field detection of polyphenol antioxidants. The experiment gives students a hands-on opportunity to utilize nanoparticle chemistry to develop…
