The randomized control trial (RCT) is the primary experimental design in education research due to its strong internal validity for causal inference. However, in situations where RCTs are not feasible or ethical, quasi-experiments are alternatives to establish causal inference. This paper serves as an introduction to several quasi-experimental…

A computational experiment investigating common organic chemistry mechanisms has been developed and implemented in a junior/senior-level physical chemistry laboratory course at two institutions. Students investigated various reactions that proceed via S[subscript N]1, S[subscript N]2, E1, and E2 mechanisms using hybrid Density Functional Theory…

In today's educational climate, physical education teachers are required to assess student learning in order to document student growth and demonstrate effectiveness as a teacher. However, because many schools limit the amount of time students spend in physical education, it is often difficult to assess student learning without it interfering with…

The Rasch model is a probabilistic model which describes the interaction of persons (test takers or survey respondents) with test or survey items and is governed by two parameters: item difficulty and person ability. Rasch measurement parallels physical measurement processes by constructing and using linear person and item measures that are…

Appropriate interpretation of assessment data requires an appreciation that tools are subject to measurement error. School psychologists recognize, at least on an intellectual level, that measures are imperfect--that test scores and other quantitative measures (e.g., rating scales, systematic behavioral observations) are best estimates of…

Pre-assessments at the start of teaching new content yielded information on what her students knew and might need, this math teacher found, but led many students to get nervous at a unit's beginning. To gauge students' understandings about math in a more inviting, stress-free way, she simply gave them drawings of protractors and asked "What…

Artificial intelligence-enabled adaptive learning systems (AI-ALS) are increasingly being deployed in education to enhance the learning needs of students. However, educational stakeholders are required by policy-makers to conduct an independent evaluation of the AI-ALS using a small sample size in a pilot study, before that AI-ALS can be approved…

Using simulation to teach business related concepts has been shown to improve student performance and learning. Developed almost two decades ago, an Enterprise Resource Planning (ERP) simulation game has seen wide adoption in traditional classrooms. However, report of its use in online classes has been rare. This teaching note shares experiences…

Environmental science is a broad, interdisciplinary field integrating aspects of biology, chemistry, earth science, geology, and social sciences. Mastery of basic science concepts and reasoning are therefore necessary for students to understand the interactions of different components in an environmental system. How do teachers identify and assess…

Students in academic contexts are expected to engage with large amounts of reading and they frequently meet unknown words and phrases in those reading materials. Previous research has shown that second and foreign language learners can acquire some of the unknown vocabulary that they encounter during reading. However, these previous findings were…

SHINE for Girls, a nonprofit with the mission of empowering young women to value their own potential and capabilities within STEM fields, employs a unique curriculum that blends math with dance. They were selected as part of HundreED's 100 Global Education Innovations for 2017. In this article, Tara Hally, Director of Programming, and Kirin Sinha,…

This project produced an online astronomy course based on the free, online OpenStax textbook. When this project was conceived, about a year before the COVID-19 pandemic, the authors had no idea that in a short period of time, most college and university classes would be online. This abrupt change in modalities of courses, from traditional,…

Skilled, ethical use of social media can advance social justice, impact policy, engage and educate the community, and elevate social workers. To assure that MSW students develop these skills, we created an assignment that required students to use a professional social media profile to advocate for a cause or policy based on findings from a needs…

A two-day workshop was designed to help rising chemical engineering sophomores prepare for the upcoming school year, curriculum, and internship opportunities. Activities include team-building exercises, presentations from faculty about upcoming classes, talks from local industry partners, interview and resume workshops, and discussions with…

A one semester undergraduate biochemistry laboratory experience is described for an understanding of recombinant technology from gene cloning to protein characterization. An integrated experimental design includes three sequential modules: molecular cloning, protein expression and purification, and protein analysis and characterization. Students…
