The undergraduate transfer process has well-documented challenges, especially for those who identify with groups historically excluded from science, technology, engineering, and mathematics (STEM) programs. Because transfer students gain later access to university networking and research opportunities than first-time-in-college students, transfer…

The importance of chemistry practical work in enhancing students' performance and 21st-century skills has been highlighted in the literature. However, Malaysian Matriculation chemistry lecturers were lack of knowledge in the 21st-century pedagogies and practiced the cook-book recipe teaching style which proved ineffective in enhancing students'…

Chemistry is a vital and highly relevant field of science that is under-represented in science centers and museums. Amidst concerns that the public is ambivalent about the chemistry field, the "Explore Science: Let's Do Chemistry" project sought to understand how to design hands-on activities that could increase the feelings of interest,…

The workplace practices of engineers have changed due to the ubiquity of digital technology. So-called techno-mathematical literacies (TmL), seen as a domain specification of 21st-century skills, are essential for future engineers. How these TmL can be fostered in their education, however, is still unclear. To address this issue, we conducted a…

In large, introductory courses, instructors and teaching assistants often struggle to provide detailed feedback on student homework in a timely manner. Here we describe a peer-reviewed homework system that provides quick turnaround while offering flexibility in the construction of homework problems. Homework is administered through a cycle, which…

Many students probably know something about space from playing computer games or watching movies and TV shows. Teachers can expose them to the real thing by launching their experiments into near space on a weather balloon. This article describes how to use high-altitude ballooning (HAB) as a culminating project to a chemistry unit on experimental…

Though school is out for the summer, ninth- and tenth-grade students at Union Intermediate High School are burning off energy playing a game of tag on the soccer field. But that is not all they are doing. They are also synthesizing and applying key chemistry concepts they have just learned related to the conditions of the early solar system. They…

Guidelines for planning a study abroad course in chemistry start with defining the course objectives and outcomes. These, in turn, guide the choice of course content and format, location, length of travel, activities, and assessment. Budgetary issues include transportation, lodging, admission fees, activities, docents and guides (including audio…

A practical exercise for developing a simple cost-effective solar ultraviolet radiation dosimeter is presented for use by middle school science students. Specifically, this exercise investigates a series of experiments utilising the historical blue print reaction, combining ammonium iron citrate and potassium hexacyanoferrate to develop an…

A basic and affordable experimental apparatus is described that measures the static contact angle of a liquid drop in contact with a solid. The image of the drop is made with a simple digital camera by taking a picture that is magnified by an optical lens. The profile of the drop is then processed with ImageJ free software. The ImageJ contact…
