Experiments are described that involve undergraduates learning concepts of nanoscience and chemistry. Students prepare nanopatterns of organosilane films using protocols of particle lithography. A few basic techniques are needed to prepare samples, such as centrifuging, mixing, heating, and drying. Students obtain hands-on skills with nanoscale…

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…

In an informal survey, just 4.93% (2014) and 6% (2015) of Human Anatomy and Physiology students stated that their favorite lab activity was using a microscope. Additionally, performance on lab practical microscopy questions was low with the average percent correct between 31.85% and 41.94%. To increase student interest, engagement and performance,…

As the need for alternative energy becomes increasingly important, energy research and related industries are rapidly expanding. This lab incorporates current energy-storage research into a second-year lab that instills real-world, industry-relevant knowledge and skills while teaching and reinforcing physical-chemistry concepts. A manganese oxide…

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…

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…

The CERN Beamline for Schools Competition gives high school students the opportunity to perform an experiment of their design using the T9 facility. Our team, 'Relatively Special', was fortunate enough to be joint winners of this global event and travel to CERN for a unique adventure. This paper gives an account of our story including the…

Multifunctional chemical analysis (MCA) systems provide a viable alternative for large scale instruction while supporting a hands-on approach to more advanced instrumentation. These systems are robust and typically use student stations connected to a remote central computer for data collection, minimizing the need for computers at every student…

Determination of enzymatic activity is a relevant experiment in teaching chemistry and biochemistry to high school and college students. A method for measuring the kinetic parameters of lactose cleavage by the enzyme lactase is described. This enzyme catalyzes the hydrolysis of lactose to galactose and glucose. The kinetic parameters can be…

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…

Lecturer-researchers, because of the duality of their profession, can introduce students directly to their research. Stimulating student interest through practical research topics enables students to see the relevance of the teaching/learning process and thereby enhance their motivation. As a major societal issue, research on renewable energies is…

In chemistry curricula, both the role of the laboratory program and the method of assessment used are subject to scrutiny and debate. The ability to identify clearly defined competencies for the chemistry laboratory program is crucial, given the numerous other disciplines that rely on foundation-level chemistry knowledge and practical skills. In…

Sustainability is emerging as a prominent curricular initiative at the undergraduate level, and as a result, involving students in real-world problems in the classroom and laboratory is an important goal. The specific problem of a dwindling supply of clean and safe drinking water is also of utmost importance and relevance. This general chemistry…

Biochemistry and molecular techniques are used for the development of the scientific practice of students. To improve both the teaching and learning quality and promote the students' motivation, this article outlines an interactive "Virtual Simulation and Actual Operation Combined" approach by using a tailored virtual practice-learning…
