In our institution, Quartet (computer software program) was a part of the curriculum which provides the students with the opportunity to work on their own in order to develop their language skills. To what extent the learners benefit from the materials and the time provided for them mainly depends on students since as Dakin suggests (1973)…

The purpose of this research was to analyze Impact of the Use of Laboratories on EFL Teaching in Primary School. The motivation of the student is one of the fundamental pillars to achieve academic success in the teaching of any subject and fundamentally in that of a second language. Implementing a language laboratory in your school creates a…

Research Experience for Teachers (RET) programs have been placing K-12 teachers in university research labs for almost three decades (Pop et al., 2010). However, the long-term impacts are rarely explored. This paper summarizes data from a survey study of 135/158 teachers (88% response rate) who participated in Stanford University's RET programs…

The purpose of this experiment was to create a simple and inexpensive flame photometer to measure the concentration of sodium in beverages, such as Gatorade. We created a nebulizer using small tubing and sprayed the sample into the base of a Bunsen burner. Adjacent to the flame was a photodiode with a filter specific for the emission of the sodium…

Dissections of human organs and animals are an important part of medical and science education but students usually express negative emotions towards dissections. Some studies show a negative influence of disgust and anxiety on motivation, interest and achievement. Therefore, reducing anxiety and disgust should be an important aim. As humor can…

The aim of this study was to examine pre-service science teachers' views about laboratory applications in science education and how their views changed through laboratory applications that were carried out for two semesters. 63 (52 females, 11 males) pre-service teachers participated in the study. The study was carried out by using pre-test and…

STEM (Science, Technology, Engineering, and Mathematics) education in the United States faces a host of problems including low recruitment and retention in STEM disciplines, under-representation of multiple segments of the US population, and a host of other issues. These problems are well recognized and a variety of solutions are being implemented…

A simple method is presented to show kids the size of a microbe--a fungus hypha--compared to a human hair. Common household items are used to make sterile medium on a stove or hotplate, which is dispensed in the cells of a weekly plastic pill box. Mold fungi can be easily and safely grown on the medium from the classroom environment. A microscope…

Previous studies have shown that pouched rats can detect the presence of "Mycobacterium tuberculosis," which causes tuberculosis, in human sputum samples obtained from clinical facilities. Although pouched rats evaluate sputum samples quickly, preparing the samples is relatively slow. The present study evaluated whether the rats can detect…

Metabolomics is a key discipline in systems biology, together with genomics, transcriptomics, and proteomics. In this omics cascade, the metabolome represents the biochemical products that arise from cellular processes and is often regarded as the final response of a biological system to environmental or genetic changes. The overall screening…

We proposed in the Basic Microbiology Subject for food science and nutrition students, a "hands-on" activity consisting on sampling student's hands for bacterial presence and identification. This is a project to be implemented in multiple laboratory classes throughout the semester, allowing students to learn, and apply general…

Remote camera-traps are commonly used to estimate the abundance, diversity, behavior and habitat use of wildlife in an inexpensive and nonintrusive manner. Because of the increasing use of remote-cameras in wildlife studies, students interested in wildlife biology should be exposed to the use of remote-cameras early in their academic careers.…

A facile, discovery-based experiment is described that introduces aliphatic substitution in an introductory undergraduate organic chemistry curriculum. Unlike other discovery-based experiments that examine substitution using two competing nucleophiles with a single electrophile, this experiment compares two isomeric, competing electrophiles…

A laboratory experiment for teaching protein separation and detection in an undergraduate biochemistry laboratory course is described. This experiment, performed in two, 4 h laboratory periods, incorporates guided inquiry principles to introduce students to the concepts behind and difficulties of protein purification. After using size-exclusion…

The properties of blood and the relative ease of access to which it can be retrieved make it an ideal source to gauge different aspects of homeostasis within an individual, form an accurate diagnosis, and formulate an appropriate treatment regime. Tests used to determine blood parameters such as the erythrocyte sedimentation rate, hemoglobin…
