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…

Author Rob Dean previously published an Illuminations article concerning "challenge" questions that encourage students to think imaginatively with approximate quantities, reasonable assumptions, and uncertain information. This article has promoted some interesting discussion, which has prompted him to present further examples. Examples…

This article argues that the role of practical work in science is overemphasised and misunderstood. Science is distinguished by the fact that it is a set of ideas about the material world and not by empirical enquiry. The latter is only one of six styles of reasoning that have been used to develop scientific ideas. The lack of clarity around the…

This evaluation was conducted with 43 second-year students, or teacher candidates, attending the science education program of an education faculty in a Turkish university. In this study, students were asked to complete a single open-ended and gap-filling questionnaire, and their answers were evaluated according to a five-point Likert-type rubric.…

Four experiments used rats to study false context fear memories. In Experiment 1, rats were pre-exposed to a distinctive chamber (context A) or to a control environment (context C), shocked after a delay in a second chamber (context B) and tested either in B or A. Rats pre-exposed to A froze just as much as control rats in B but more than control…

Laboratories are generally regarded as critical to engineering education, and yet educational institutions face significant challenges in developing and maintaining high-quality laboratory facilities. Remote laboratories are increasingly being explored as a partial solution to this challenge, with research showing that--for the right learning…

With the current popularity and widespread use of high-tech and telecommunication products, digital information with varied forms of software, hardware, and multimedia was engaged in designs for entertainment and daily life; its related products are sweeping the globe. On the other hand, the rapid development of 3D printing technology further…
