de Roo, Nina; Amede, Tewodros; Elias, Eyasu; Almekinders, Conny; Leeuwis, Cees – Journal of Agricultural Education and Extension, 2023
Purpose: Agricultural extension services in poor countries often identify opinion leaders based on criteria such as wealth and social status. We explore the effectiveness of this top-down approach by analysing the role of so-called model and nodal farmers in the diffusion of malt barley in a highland community in Ethiopia. Research approach: We…

Tamimi, Nancy; Kienzler, Hanna; Hammoudeh, Weeam; Giacaman, Rita – International Journal of Training and Development, 2022
To address the gap in locally driven mental health capacity strengthening initiatives in the occupied Palestinian territory (oPt), researchers from Birzeit University (BZU) and King's College London (KCL) developed a unique short course focusing on the intersection between methods, mental health, and conflict. The course was delivered in the West…

Rusticus, Shayna A.; Wilson, Derek; Jarus, Tal; O'Flynn-Magee, Kathy; Albon, Simon – Learning Environments Research, 2022
The desire to support student learning and professional development, in combination with accreditation requirements, necessitates the need to evaluate the learning environment of educational programs. The Health Education Learning Environment Survey (HELES) is a recently-developed global measure of the learning environment for health professions…

Cain, Liz; Goldring, John E.; Scott Jones, Julie – Higher Education, Skills and Work-based Learning, 2022
Purpose: The purpose of the paper is to discuss the "Q-Step in the Community" programme, part of the Q-Step Centre based in the Sociology Department at Manchester Metropolitan University, designed to help address the skills gap in quantitative methods (QM) that is evident across parts of the UK higher-education sector. "Q-Step in…

Timothy Lycurgus; Ben B. Hansen; Mark White – Grantee Submission, 2022
We present an aggregation scheme that increases power in randomized controlled trials and quasi-experiments when the intervention possesses a robust and well-articulated theory of change. Intervention studies using longitudinal data often include multiple observations on individuals, some of which may be more likely to manifest a treatment effect…

Günhan, Burak Kürsad; Friede, Tim; Held, Leonhard – Research Synthesis Methods, 2018
Network meta-analysis (NMA) is gaining popularity for comparing multiple treatments in a single analysis. Generalized linear mixed models provide a unifying framework for NMA, allow us to analyze datasets with dichotomous, continuous or count endpoints, and take into account multiarm trials, potential heterogeneity between trials and network…

Rosenthal, Jeffrey S. – Teaching Statistics: An International Journal for Teachers, 2018
This article advocates that introductory statistics be taught by basing all calculations on a single simple margin-of-error formula and deriving all of the standard introductory statistical concepts (confidence intervals, significance tests, comparisons of means and proportions, etc) from that one formula. It is argued that this approach will…

Garcia, Nichole M.; López, Nancy; Vélez, Verónica N. – Race, Ethnicity and Education, 2018
Critical race theory (CRT) in education centers, examines, and seeks to transform the relationship that undergirds race, racism, and power. CRT scholars have applied a critical race framework to advance research methodologies, namely qualitative interventions. Informed by this work, and 15 years later, this article reconsiders the possibilities of…

Wind, Stefanie A.; Patil, Yogendra J. – Educational and Psychological Measurement, 2018
Recent research has explored the use of models adapted from Mokken scale analysis as a nonparametric approach to evaluating rating quality in educational performance assessments. A potential limiting factor to the widespread use of these techniques is the requirement for complete data, as practical constraints in operational assessment systems…

Raykov, Tenko; Goldammer, Philippe; Marcoulides, George A.; Li, Tatyana; Menold, Natalja – Educational and Psychological Measurement, 2018
A readily applicable procedure is discussed that allows evaluation of the discrepancy between the popular coefficient alpha and the reliability coefficient of a scale with second-order factorial structure that is frequently of relevance in empirical educational and psychological research. The approach is developed within the framework of the…

Inan, Tugbay – Universal Journal of Educational Research, 2018
The impact of the scoring systems on home field advantage in the highest-level Turkish soccer division, Turkish Super League, between the 1959-1960 and 2016-2017 seasons, was aimed to be examined in this study. 2-point system was used in Turkish Soccer Leagues between 1959 and 1987. Since 1987-1988 season, the 3-point system has been started to be…

Luo, Yong – Educational and Psychological Measurement, 2018
Mplus is a powerful latent variable modeling software program that has become an increasingly popular choice for fitting complex item response theory models. In this short note, we demonstrate that the two-parameter logistic testlet model can be estimated as a constrained bifactor model in Mplus with three estimators encompassing limited- and…

Falk, Carl F.; Monroe, Scott – Educational and Psychological Measurement, 2018
Lagrange multiplier (LM) or score tests have seen renewed interest for the purpose of diagnosing misspecification in item response theory (IRT) models. LM tests can also be used to test whether parameters differ from a fixed value. We argue that the utility of LM tests depends on both the method used to compute the test and the degree of…

Biggs, Michael – Sociological Methods & Research, 2018
Since the 1970s, catalogs of protest events have been at the heart of research on social movements. To measure how protest changes over time or varies across space, sociologists usually count the frequency of events, as either the dependent variable or a key independent variable. An alternative is to count the number of participants in protest.…

Can, Ibrahim; Cihan, Hamit; Ari, Erdal; Bayrakdaroglu, Serdar – Journal of Education and Training Studies, 2018
The aim of this investigation is to compare velocity and power variables during loaded-squat jump (SJ[subscript Loaded]) exercise of national athletes dealing with different sports branches and to identify whether velocity and power parameters become different or not according to branches. In accordance with this purpose, a total of 36 national…
