The teaching of histology has changed dramatically with virtual microscopy. Fewer students of histology spend significant time viewing slides on a microscope and instead study images available in digital slide sets, generally accessible via the internet. However, students must still be able to correctly identify the defining characteristics of…

In the author's large, urban high school, enrollment in a laboratory science is mandatory. While the student participation rate for lab activities is over 98%, the turn-in rate for traditional lab reports averages just 35% to 85%. Those students who don't produce a lab report miss a critical opportunity to improve their skills in scientific…

Perovskite solar cells have garnered exponential research interest due to their facile fabrication, solution processability, and low cost. However, there have been limited efforts to integrate this class of materials into the undergraduate laboratory curriculum. Therefore, we designed an integrated laboratory experiment in our upper-division…

The aim of this study is to examine the personal professional development efforts of science and technology teachers in their fields with regard to some variables. These variables were determined as gender, year of seniority and sufficiency level of the laboratory equipment. Moreover, the relation between the actual efforts exerted by science and…

A simple and reliable didactic laboratory has been developed to illustrate fundamental concepts of hydrophilicity, hydrophobicity, wetting, and spreading phenomena for undergraduate students. The described laboratory includes preparation of surfactant solutions at different concentrations and applying droplets of these solutions on a hydrophobic…

Agricultural mechanics instruction includes a broad array of machinery, structures, and technical systems, as well as a diverse workforce. Virtually every aspect of agriculture has a mechanics component and a large portion of secondary agriscience curriculum is devoted specifically to teaching agricultural mechanics. Further, the agricultural…

Laboratory practicals engage students in complex thinking to build their scientific knowledge and understanding. Surprisingly few studies connect the development of students' cognitive and metacognitive skills for learning in the laboratory practical with foundational skills for researching. Librarians strive to establish teaching partnerships…

Although lab activities play an important role in physics teaching, many of these activities do not attain the expected objectives. Many reasons can be advanced for this, such as a lack of apparatus/equipment in schools, limits to the lab time allocated, teachers' lack of knowledge and skills about lab-oriented teaching methods or the teachers'…

This paper reports our classroom implementation of a new remote laboratory (RL) system, which was developed by using innovative ideas and methods for applying technology-enhanced learning to secondary school science education (Grades 7-9 or Ages 12-14). The newly developed RL system, which involves 8 remote experiments, was tested with 32…

A variety of factors contribute to attrition in science, technology, engineering, and mathematics (STEM) education at the community college level including underpreparedness, lack of confidence, and broader socioeconomic issues. This work describes our efforts to improve student learning and overall success in a community college General Biology I…

A pressing concern in all agricultural mechanics courses is safety. Lab activities have an inherent propensity to cause serious injury. The safety practices which are taught by teachers are largely dependent on the equipment in the laboratory and the resources available to the program. Various researchers have indicated that problems have existed…

Educational researchers have conducted very few studies on the subjective experiences of both trained and self-taught auto mechanics (Barber, 2003, 2004; Nelsen, 1997, 2010). Further, no present studies explore the subjective experience of the automotive instructor as he or she experiences uncertainty in the automotive lab. This study addresses a…

Though many undergraduates are interested in medicine, relatively few experiments related to drug design and development are included in introductory chemistry laboratory courses. In this experiment, aqueous solutions of four different drugs (acetaminophen, caffeine, phenacetin, and sulfanilamide) are extracted using 1-octanol, a mimic of the…

Lactone-size identification of [subscript D]-ribonolactone derivatives has been debated for four decades due to complex lactone-ring rearrangements and acetal migration. This laboratory experiment for an upper-division undergraduate organic chemistry laboratory course describes a fast and reliable assignment of lactone-size derivatives from…

A laboratory experiment is described in which students compare two methods for the determination of the calcium content of commercial dietary supplement tablets. In a two-week sequence, the sample tablets are first analyzed via complexometric titration with ethylenediaminetetraacetic acid and then, following ion exchange of the calcium ion present…
