This article focuses on learning gains in the area of higher education STEM (science, technology, engineering, and mathematics) through new approaches to the formative assessment feedback cycle. Learning gains were examined for stratified randomized comparison and two treatment groups of 943 students organized into 41 laboratory sections in…

Background: We present an analysis of students' responses to application-based questions on the topic of growth and control of microorganisms, from a questionnaire administered to 348 second and third year students of an Indian university who were enrolled in its undergraduate programs in Biotechnology or Microbiology. We examined aspects of the…

In this article, we discuss what it means to learn troublesome "threshold concepts" about writing that cannot be adequately grappled with in a single course or assignment. Here, two faculty members and a graduate of a writing major reflect on elements of the writing curriculum, the writing center practicum, and the learning dispositions…

One of my principal goals at the University of Minnesota is to transform the university's entry-level geoscience program into an effective ''concluding'' geoscience course that provides students with a clear understanding of the many interactions between Earth processes and human society. Although place-based learning appeared to be a promising…

We present a simple and accurate experiment to obtain the speed of sound in air using a conventional speaker and a microphone connected to a computer. A free open source digital audio editor and recording computer software application allows determination of the time-of-flight of the wave for different distances, from which the speed of sound is…

Scalpels are utilized by many different user groups for such purposes as medical procedures and dissection. Injuries caused by scalpels are a potential risk for scalpel users, and include injuries that may occur while mounting and removing the scalpel blade. Between 10% and 20% of all scalpel injuries in education and healthcare settings are…

In their article, "Space, relations, and the learning of science," Wolff-Michael Roth and Pei-Ling Hsu draw our attention to the importance of field in the teaching and learning of science. While the Roth and Hsu study is focused on the scientific research laboratory as an internship setting for the teaching of science, this response to…

Many of us have grabbed two pieces of aluminum foil and a paper towel, quickly sandwiched them together, and exclaimed in lecture, "Look! It's easy to make a capacitor!" Then we move on from there, calculating things such as capacitances with various dielectrics or plate sizes, the capacitance of capacitor networks, RC circuits,…

We have developed an upper-level undergraduate laboratory exercise that enables students to replicate a key experiment in developmental biology. In this exercise, students have the opportunity to observe live chick embryos and stain the apical ectodermal ridge, a key tissue required for development of the vertebrate limb. Impressively, every…

In this laboratory module, introductory biochemistry students are exposed to two-dimensional [superscript 1]H-nuclear magnetic resonance of glycerophospholipids (GPLs). Working in groups of three, students enzymatically synthesized and purified a variety of 2-acyl lyso GPLs. The structure of the 2-acyl lyso GPL was verified using [superscript…

An increasingly interconnected world requires people to become versatile communicators in a variety of different settings. Language centers have a critical role to play in this process by offering language and culture training in multiple languages to students, professionals and the wider community alike. They may do so from the perspective of…

Youth with autism spectrum disorder often have complex medical needs. Disruptions of healthcare during the transition from pediatric to adult healthcare may put youth with autism spectrum disorder at higher risk of medical emergencies and high medical costs. We conducted a study among transition-age youth (14-25 years old) receiving healthcare at…

Pre-service teachers frequently express negative prejudices towards science and the methodologies traditionally used during their training. Gamification is a booming technology based on combining the psychological aspects, mechanics and dynamics of a game in non-ludic environments. The use of gamification has shown good outcomes in terms of…

Across the nation, there is a large shortage of teachers in several subject areas (Daniel, 2015; Milliard, 2015; Sutcher, Darling-Hammond, & Carver-Thomas, 2016). In agricultural education, many teachers are leaving the profession within the first five years of beginning their teaching careers (Tippens, Ricketts, Morgan, Navaro, &…

Most of the research on argumentation in science education has documented the myriad flaws in students' argumentation, and the difficulties teachers have organising productive arguments in the classroom. We apply a sociocultural framework to argue that productive argumentation emerges from a classroom culture in which its practice meaningfully…
