Direct linkSmith, Kendal N.; Lamb, Kristen N.; Henson, Robin K. – Gifted Child Quarterly, 2020
Multivariate analysis of variance (MANOVA) is a statistical method used to examine group differences on multiple outcomes. This article reports results of a review of MANOVA in gifted education journals between 2011 and 2017 (N = 56). Findings suggest a number of conceptual and procedural misunderstandings about the nature of MANOVA and its…

Peer reviewedGorard, Stephen; Gorard, Jonathan – International Journal of Social Research Methodology, 2016
This brief paper introduces a new approach to assessing the trustworthiness of research comparisons when expressed numerically. The 'number needed to disturb' a research finding would be the number of counterfactual values that can be added to the smallest arm of any comparison before the difference or 'effect' size disappears, minus the number of…

Hand, Brian; Shelley, Mack C.; Laugerman, Marcia; Fostvedt, Luke; Therrien, William – Science Education, 2018
In a cluster-randomized study, we investigate the impact of an argument-based approach to teaching science in elementary school on science learning and critical thinking skills. Forty-eight schools participated in the study, with data on 9,963 students across the 2 years of the intervention. Annual standardized tests assessing science content…

Jorgensen, Estelle R.; Ward-Steinman, Patrice Madura – Journal of Research in Music Education, 2015
The purpose of this study was to examine evidence of a hypothesized shift in the operative research paradigms in music education during the first quarter century of the publication of the "Journal of Research in Music Education," during the period 1953 to 1978. This shift was from humanities-oriented historical and philosophical studies…

In the era of contemporary society, which revolves around the fast information science revolution, the pupil is no longer just an observer in the educational process but rather an active constructor of one's own knowledge. Current didactic theories proclaim teaching, in which the teacher is an instructor and a facilitator, and as such should…

Calucag, Lina S. – Journal of Education and Practice, 2016
This is an experimental study, made used of the non-randomized experimental and control groups, pretest-posttest designs. The experimental and control groups were two separate intact classes in Algebra. For a period of twelve sessions, the experimental group was subjected to the scientific heuristic method, but the control group instead was given…

Shamuganathana, Sheila; Karpudewan, Mageswary – Chemistry Education Research and Practice, 2017
Existing studies report on the importance of instilling environmental literacy among students from an early stage of schooling to enable them to adopt more pro-environmental behaviors in the near future. This quasi-experimental study was designed to compare the level of environmental literacy among two groups of students: the experimental group (N…

Dexter, Douglas D. – International Journal for Research in Learning Disabilities, 2012
A pretest-posttest comparison group design was used to investigate the effects of a semantic mapping lesson plus visual display versus a semantic mapping lesson alone on adolescents' with learning disabilities (LD) ability to gain and maintain factual knowledge from expository social studies material. In addition, a posttest only comparison group…

Thompson, Bruce – Middle Grades Research Journal, 2009
The present article provides a primer on using effect sizes in research. A small heuristic data set is used in order to make the discussion concrete. Additionally, various admonitions for best practice in reporting and interpreting effect sizes are presented. Among these is the admonition to not use Cohen's benchmarks for "small," "medium," and…
