Kalkan, Ömür Kaya; Kelecioglu, Hülya – Educational Sciences: Theory and Practice, 2016
Linear factor analysis models used to examine constructs underlying the responses are not very suitable for dichotomous or polytomous response formats. The associated problems cannot be eliminated by polychoric or tetrachoric correlations in place of the Pearson correlation. Therefore, we considered parameters obtained from the NOHARM and FACTOR…

Brandon, Paul R.; Harrison, George M.; Lawton, Brian E. – American Journal of Evaluation, 2013
When evaluators plan site-randomized experiments, they must conduct the appropriate statistical power analyses. These analyses are most likely to be valid when they are based on data from the jurisdictions in which the studies are to be conducted. In this method note, we provide software code, in the form of a SAS macro, for producing statistical…

Genç, Murat – Online Submission, 2015
The purpose of this study was to investigate the effect of scientific studies on students' scientific literacy and attitude towards science course. For the study, a middle school science study group was established by randomly selecting 30 students from the 6th, 7th, and 8th grades. Participating students were given information about the…

Adedokun, Omolola A.; Burgess, Wilella D. – Journal of MultiDisciplinary Evaluation, 2012
Background: Although McNemar Test is the most appropriate tool for analyzing pre-post differences in dichotomous items (e.g., "yes" or "no", "correct" or "incorrect", etc.), many scholars have noted the inappropriate use of Pearson's Chi-square Test by researchers, including social scientists and evaluators,…

Su, Jun-Ming; Lin, Huan-Yu – Educational Technology & Society, 2015
In recent years, software operating skills, the ability in computer literacy to solve problems using specific software, has become much more important. A great deal of research has also proven that students' software operating skills can be efficiently improved by practicing customized virtual and simulated examinations. However, constructing…

Scranton, Melissa Arnold – ProQuest LLC, 2013
The purpose of this study was to gain a better understanding of how students think in a technological environment. This was accomplished by exploring the differences in the thinking of students while they worked in a technological environment and comparing this to their work in a paper and pencil environment. The software program TinkerPlots:…

Tas, Erol – Journal of Education and Training Studies, 2015
The main objective of this study is to research the effects of a student gains and activity based virtual material on students' success, permanence and attitudes towards science lesson, developed for science and technology lesson 6th grade "Systems in our body" unit. The study, which had a quasi-experimental design, was conducted with…

Annetta, Leonard; Vallett, David; Fusarelli, Bonnie; Lamb, Richard; Cheng, Meng-Tzu; Holmes, Shawn; Folta, Elizabeth; Thurmond, Brandi – Journal of Computers in Mathematics and Science Teaching, 2014
The purpose of this study was to examine the effect Serious Educational Games (SEGs) had on student interest in science in a federally funded game-based learning project. It can be argued that today's students are more likely to engage in video games than they are to interact in live, face-to-face learning environments. With a keen eye on…

Yang, Chih-Wei; Kuo, Bor-Chen; Liao, Chen-Huei – Turkish Online Journal of Educational Technology - TOJET, 2011
The aim of the present study was to develop an on-line assessment system with constructed response items in the context of elementary mathematics curriculum. The system recorded the problem solving process of constructed response items and transfered the process to response codes for further analyses. An inference mechanism based on artificial…

Churchwell, Don Wesley – ProQuest LLC, 2009
This study examined the relationship between STAR Math gains and TCAP composite scores. The purpose of this study was to determine if there was a significant relationship between STAR Math pretest and posttest gains over the course of the 2005-2006 academic year through the use of the STAR Math software program and TCAP math composite scores at…

Shavalier, Maria – Journal of Educational Computing Research, 2004
This study investigated whether the software Virtus WalkThrough Pro could be used to enhance middle school children's spatial ability as measured by the Paper Folding, Mental Rotations, and Eliot-Price Tests. The study also investigated whether the use of this software impacted males differently than females, or users with high spatial ability…

Miyamoto, Karen A. – Research and Issues in Music Education, 2005
A pretest-posttest experimental design was utilized to determine the efficacy of the Yuba Method on inaccurate elementary singers. Testing of pitch accuracy was analyzed using the Sona-Speech Model 3600 software program. Inaccurate singers (N=168) from a population of 320 fourth, fifth, and sixth grade students, were divided into three subgroups…

Stamper, John, Ed.; Pardos, Zachary, Ed.; Mavrikis, Manolis, Ed.; McLaren, Bruce M., Ed. – International Educational Data Mining Society, 2014
The 7th International Conference on Education Data Mining held on July 4th-7th, 2014, at the Institute of Education, London, UK is the leading international forum for high-quality research that mines large data sets in order to answer educational research questions that shed light on the learning process. These data sets may come from the traces…
