Iannario, Maria; Manisera, Marica; Piccolo, Domenico; Zuccolotto, Paola – Sociological Methods & Research, 2020
In analyzing data from attitude surveys, it is common to consider the "don't know" responses as missing values. In this article, we present a statistical model commonly used for the analysis of responses/evaluations expressed on Likert scales and extended to take into account the presence of don't know responses. The main objective is to…

A green chemistry experiment is presented for teaching an undergraduate quantitative analysis/analytical chemistry laboratory class through the use of black tea leaf extract for the determination of iron in supplement tablets. Dried tea leaf is a safe, low cost, and widely available source of natural extract that can be used in place of more toxic…

Menekse, Muhsin – Journal of Experimental Education, 2020
This study addressed the role of the reflection-informed learning and instruction (RILI) model on students' academic success by using CourseMIRROR mobile system. We hypothesized that prompting students to reflect on confusing concepts stimulates their self-monitoring activities according to which students are expected to review their…

Simões, Gustavo Borges; Badolato, Paulo Victor e Silva; Ignácio, Marcelo Dante; Cerqueira, Eduardo Coelho – Journal of Chemical Education, 2020
Zinc oxide is a common additive in food, cosmetics, and medicines. Here, we describe the validation of methods to analyze two pharmaceutical samples containing ZnO--talc powder and dermal ointment--by ethylenediaminetetraacetic acid (EDTA) titration. The methods developed were implemented as a practical class to students of a Quantitative Analysis…

Coletta, Vincent P.; Steinert, Jeffrey J. – Physical Review Physics Education Research, 2020
Recently, Nissen et al. argued in this journal for the use of Cohen's d, in place of the more commonly used normalized gain, in the analysis of preinstruction and postinstruction scores on concept inventories used to measure the effectiveness of instruction. Their reason for advocating such a change is that they say normalized gains are…

Woessner, Matthew C.; Maranto, Robert – International Journal of Educational Reform, 2020
Despite efforts to redress racial grievances, American's most progressive institutional sector, higher education, suffers racial incidents with disturbing frequency. We hypothesize that one explanation lies in the bureaucratization of higher education. Various trends have led to what Benjamin Ginsberg calls "the fall of the faculty" and…

Thompson, W. Burt – Teaching of Psychology, 2019
When a psychologist announces a new research finding, it is often based on a rejected null hypothesis. However, if that hypothesis is true, the claim is a false alarm. Many students mistakenly believe that the probability of committing a false alarm equals alpha, the criterion for statistical significance, which is typically set at 5%. Instructors…

Woods, Amelia Mays; Ayers, Suzan F. – Journal of Teaching in Physical Education, 2019
There are several factors that contribute to the shrinking supply of teachers. Fewer individuals are pursuing teaching as a career; in the United States, for example, teacher education enrollments plunged 35% between 2009 and 2014 (Berry & Shields, 2017). In direct relation to the decrease in students entering preservice teaching, fewer…

Sablan, Jenna R. – American Educational Research Journal, 2019
Critical race theory (CRT) has been used in educational literature to emphasize the influence of racism on educational opportunity and the assets of students of color. Quantitative methods appear antithetical to CRT tenets according to some, but this article endeavors to show why this is not the case, based on both historical and contemporary…

Aiken, John M.; Henderson, Rachel; Caballero, Marcos D. – Physical Review Physics Education Research, 2019
Physics education research (PER) has used quantitative modeling techniques to explore learning, affect, and other aspects of physics education. However, these studies have rarely examined the predictive output of the models, instead focusing on the inferences or causal relationships observed in various data sets. This research introduces a modern…

Rode, Jacob B.; Ringel, Megan M. – Teaching of Psychology, 2019
The current study examines whether R or SPSS output induces greater initial anxiety in students and whether anxiety toward one or both changes after being taught one type of software output throughout the course. The authors each taught an introductory statistics course, with the first course (n = 43) teaching R output exclusively and the second…
