This paper extends the use of Generalizability Theory to the measurement of extemporaneous L2 speech through the lens of speech perception. Using six datasets of previous studies, it reports on "G studies"--a method of breaking down measurement variance--and "D studies"--a predictive study of the impact on reliability when…

[This paper is part of the Focused Collection on Instructional labs: Improving traditions and new directions.] Research on nontraditional laboratory (lab) activities in physics shows that students often expect to verify predetermined results, as takes place in traditional lab activities. This understanding of what is taking place, or…

Despite their centrality to undergraduate teaching in U.S. universities, few studies focus on ITA's and their experiences within ITA training classes. Through a multiple case study of two In-Service ITA's (China, Taiwan) investments (Darvin & Norton, 2015) in one such class, it became clear how idiosyncratic are perception of these courses:…

All students studying Computer Science (CS) deserve to have their basic psychological need for belonging satisfied. In this dissertation, I present two studies of belonging among CS students at the University of Washington-Paul G. Allen School of Computer Science and Engineering. In the first study, my collaborators implemented a resubmission…

This research examines one lead teacher's and two assistant teachers' emotional discomfort as they participated in an eight-month collaborative ethnography of 19 children's peer-culture aggression in an early care and education classroom in the USA. Two questions guided this analysis: (1) What are the emotional themes of teachers in relation to…

Despite growing evidence of positive student outcomes from course-based undergraduate research experiences (CUREs), little consideration has been given to employing graduate teaching assistants (GTAs) as CURE instructors. GTAs may be novice researchers and/or teachers and likely vary in their interest in teaching a CURE. Guided by expectancy-value…

An honors practitioner describes various challenges in onboarding and training a new academic advisor during the coronavirus crisis. Virtual interaction and multitasking skills prove fruitful for training in best practices while also bringing experienced and first-year students together in unexpected ways. The author cites several improvements in…

In this paper, the guest editors consider the direction of research on teaching assistants (TAs), and how academics can elevate the field within the spheres of education and the social sciences. We begin by unpicking, and endorsing, Giangreco's idea of applying the 'Maslow's Hammer test' (expressed in this special issue) to manuscripts about…

The reliance on teaching assistants (TAs) for inclusion is discussed in relation to the quality of instructional support. Swiss policy stipulates two distinct models for TAs working in mainstream classes: they can either be employed to work with a particular pupil with special educational needs (SEN) or be employed as a general aide to provide…

Many recent studies document the difficulties that students experience when learning organic chemistry, often due to the complex visualization and reasoning skills required to successfully understand the ways molecules interact in specific environments. Many of these studies call on instructors to improve their teaching strategies to support…

Science as an enterprise has been and continues to be exclusionary, perpetuating inequities among whose voice is heard as well as what/whose knowledge is recognized as valid. Women, people of color, and persons with disabilities are still vastly outnumbered in science and engineering by their White, male counterparts. These types of imbalances…

Teaching skills are fundamental for academic positions, which combine research and teaching activities. Thus, universities should look for candidates with excellent research records and teaching experience or skills; another strategy is the training of teaching staff. On the other hand, when dealing with already in-service teachers, the challenges…

A significant number of international graduate students teach undergraduates in science departments as teaching assistants, often as laboratory instructors. The compelling cultural differences between international teaching assistants (ITAs) and their students in the U.S. have led to profound communication problems, which was often referred to as…

Chatbot usage is evolving rapidly in various fields, including higher education. The present study's purpose is to discuss the effect of a virtual teaching assistant (chatbot) that automatically responds to a student's question. A pretest-posttest design was implemented, with the 68 participating undergraduate students being randomly allocated to…

Minoritized students in civil engineering frequently experience subtle negative attitudes or biases based on their race and gender. These subtle attitudes and biases are known as microaggressions and are reasons for low self-efficacy and retention in civil engineering. Previous studies demonstrated the prevalence of microaggressions in engineering…
