The "TAS2R38" alleles that code for the PAV/AVI T2R38 proteins have long been viewed as benign taste receptor variants. However, recent studies have demonstrated an expanding and medically relevant role for "TAS2R38." The AVI variant of T2R38 is associated with an increased risk of both colorectal cancer and "Pseudomonas…

Every introductory astronomy class encounters Galileo during the course as the first man to systematically study the sky with a telescope. Every Astronomy 101 student meets Galileo as one of the major catalysts behind the shift from the Ptolemaic to the Copernican system and as one of the great minds behind the scientific method. But most of the…

The hearts of sports fans were stirred recently by the fastest-ever try scored in international rugby. Welsh winger Dafydd Howells crossed the Fijian try line to score a mere six seconds after Angus O'Brien had started the game with a kickoff, in one of the fixtures in rugby's Junior World Cup played on June 2, 2014, in New Zealand. This…

New experiments for undergraduate students are needed to stimulate experiential learning in the laboratory while providing valuable training for future career development. Iodine deficiency remains a major public health concern that is monitored by measuring the median urinary iodide concentration of a population. In this context, we have…

A common method that scientists use to validate a theory is to utilize known principles and laws to produce results on specific settings, which can be assessed using the appropriate experimental methods and apparatuses. Smartphones have various sensors built-in and could be used for measuring and logging data in physics experiments. In this work,…

Along-standing energy lab involves dropping bouncy balls and measuring their rebound heights on successive bounces. The lab demonstrates a situation in which the mechanical energy of a system is not conserved. Although students enjoyed the lab, the author wanted to deepen their thinking about energy, including the connections to motion, with a new…

While the equivalence between online and traditional classrooms has been well researched, very little effort has been expended to do such comparisons for college level introductory chemistry. The existing literature has only one study that investigated chemistry lectures at an entire course level as opposed to particular course components such as…

A new method for teaching advanced laboratories at the undergraduate level is presented. The intent of this approach is to get students more engaged in the lab experience and apply critical thinking skills to solve problems. The structure of the lab is problem-based and provides students with a research-like experience. Students read the current…

Students find it hard to understand acid-base homeostasis and the mechanisms involved in compensating for acid-base imbalances, including the role of the lungs and kidneys in this process. We have developed a laboratory activity based on collaborative problem-based learning and human patient simulators (HPSs) to teach this topic. Students (n=50)…

This study is inspired by laboratory studies demonstrating that distributing study sessions over time better supports learning and retention than clustering sessions. We compare two implementations of a multi-day inquiry science unit: in the clustered instruction condition, students completed an inquiry unit in five consecutive class periods. In…

Professional manpower education and training on research equipment handling are very important for the efficient management, utilization, and operation of research equipment, which in turn is essential for obtaining excellent research results. The government-level efforts to offer such are an essential ingredient of a successful national R&D…

One of the most important objectives of teachers, parents, school administrators, and students is to improve student scores on standardized tests, such as the State of Texas Assessment for Academic Readiness (STAAR) in eighth-grade science. This quasi-experimental study examined the science achievement scores between schools that used different…

This study investigated teachers' characteristics and availability of laboratory as predictors of physics students' performance in Ilorin. 40 teachers and 400 students formed the sample size. The instruments used were PTQ and PSPT. The PSPT was a set of 15 theory questions on the topics taught by the teachers to the students. The scores were used…

Many Anglo-American universities have undertaken a paradigm shift in how the dissection of human material is approached, such that students are encouraged to learn about the lives of body donors, and to respectfully "personalize" them as human beings, rather than treating the specimens as anonymous cadavers. For the purposes of this…

The purpose of this study is to determine the perceptions of teacher candidates on the concepts of science course, science laboratory, science teacher and science student using metaphors. In this study, the phenomenological research method was used. The participants consisted of a total of 58 first year students who are studying at the department…
