White, Simon R.; Bonnett, Laura J. – Teaching Statistics: An International Journal for Teachers, 2019
The statistical concept of sampling is often given little direct attention, typically reduced to the mantra "take a random sample". This low resource and adaptable activity demonstrates sampling and explores issues that arise due to biased sampling.

Therrien, Mona; Calder, Beth L.; Castonguay, Zakkary J. – Journal of Food Science Education, 2018
Students in the Didactic Program in Dietetics (DPD) at the University of Maine were exposed to the cheese-making process, within a lab setting of two hours, utilizing an accelerated recipe for a Queso Fresco-style cheese. The purpose of this project was to provide students with a novel, hands-on learning experience, which covered concepts of…

Marshall, Jill A.; Banner, Jay L.; You, Hye Sun – Journal of College Science Teaching, 2018
This study investigated the interaction of disciplinary and interdisciplinary learning in a team-taught, first-year, interdisciplinary sustainability course. We surveyed (pre/post) both STEM (science, technology, engineering, and mathematics) and non-STEM majors (N = 241), assessing attitudes and content knowledge. Responses were analyzed using…

Metzger, Kelsey J.; Smith, Brittany A.; Brown, Ethan; Soneral, Paula A. G. – Journal of College Science Teaching, 2018
This study describes the development and implementation of an iterative diagnostic and intervention routine designed to elicit and quantitatively describe aspects of student metacognition, affect, and study habits in a first-year undergraduate biology course. The Student Metacognition, Affect, and Study Habits (SMASH) inventory is a…

Bruck, Laura B.; Bruck, Aaron D. – Journal of College Science Teaching, 2018
Recruitment and retention in the sciences is both difficult and crucial, especially in the community college setting. In this study, the resources used by General Chemistry I students at two different public, predominantly two-year colleges in two states were studied via surveys for a semester. Data were analyzed with respect to student attitudes…

Bosman, Lisa B.; O'Brien, Steve; Shanta, Susheela; Strimel, Greg J. – Technology and Engineering Teacher, 2018
The purpose of this article is to provide educators with resources to help students establish a deeper understanding of the application and role of statistical analysis within the design and innovation process. Quantitative analyses are often taught and applied through design activities, especially during testing or experimenting phases of design.…

Paek, Insu; Cui, Mengyao; Öztürk Gübes, Nese; Yang, Yanyun – Educational and Psychological Measurement, 2018
The purpose of this article is twofold. The first is to provide evaluative information on the recovery of model parameters and their standard errors for the two-parameter item response theory (IRT) model using different estimation methods by Mplus. The second is to provide easily accessible information for practitioners, instructors, and students…

Flohic, Hélène M. L. G. – Journal of Astronomy & Earth Sciences Education, 2017
A common challenge among university professors is how to best design undergraduate courses to successfully enhance students' attitudes. To compare which curriculum was more efficient at fostering a positive attitude towards science in general, I studied the impact of two different general education science courses on the attitudes of college…

Cagle, Jack F. – Journal of Organizational and Educational Leadership, 2017
A decade of research on school discipline has made society keenly aware of the "elephant in the room." Overwhelmingly, Black students are "wounded" permanently when they are suspended over and over for offenses that are overlooked when their white counterparts commit the same infraction. Since Black students are suspended…

James, Joan K.; Matthews, Robert W. – Science and Children, 2017
In their classrooms, the authors observed students experiencing meaningful and memorable learning when they were immersed in scientific inquiry involving Bess beetles. Students who learn from active, experiential instruction, find such learning to be exciting and emotionally engaging. As a result, they learn more deeply and effectively. This…

Sandusky, Peter Olaf – Journal of Chemical Education, 2017
Metabolomics applies multivariate statistical analysis to sets of high-resolution spectra taken over a population of biologically derived samples. The objective is to distinguish subpopulations within the overall sample population, and possibly also to identify biomarkers. While metabolomics has become part of the standard analytical toolbox in…

Perry, Rebecca R.; Lewis, Catherine C. – Teaching Children Mathematics, 2017
The authors recently conducted a randomized controlled trial that showed a significant impact of teachers' lesson study, supported by mathematical resources, on both teachers' and students' understanding of fractions. The research and mathematical resources are described in the second part of this article. First the authors examine some of the…

St. John, Kristen; McNeal, Karen S. – Journal of Geoscience Education, 2017
During the past two decades, the Geoscience Education Research (GER) community has been increasingly recognized as an evidence-based research subdiscipline in the geoscience and in the larger discipline-based education research (DBER) field. Most recently, the GER community has begun to address the current state of the field and discuss the best…

Petrosino, Anthony J.; Mann, Michele J. – Journal of College Science Teaching, 2018
Although data modeling, the employment of statistical reasoning for the purpose of investigating questions about the world, is central to both mathematics and science, it is rarely emphasized in K-16 instruction. The current work focuses on developing thinking about data modeling with undergraduates in general and preservice teachers in…

Case, Catherine; Whitaker, Douglas – Mathematics Teacher, 2016
In the criminal justice system, defendants accused of a crime are presumed innocent until proven guilty. Statistical inference in any context is built on an analogous principle: The null hypothesis--often a hypothesis of "no difference" or "no effect"--is presumed true unless there is sufficient evidence against it. In this…
