For the two-way factorial design in analysis of variance, the current article explicates and compares three methods for controlling the Type I error rate for all possible simple interaction contrasts following a statistically significant interaction, including a proposed modification to the Bonferroni procedure that increases the power of…

Introduction: The use of averaged topic-level scores can result in the loss of valuable data and can cause misinterpretation of the effectiveness of system performance. This study aims to use the scores of each document to evaluate document retrieval systems in a pairwise system evaluation. Method: The chosen evaluation metrics are document-level…

We present three strategies to replace the null hypothesis statistical significance testing approach in psychological research: (1) visual representation of cognitive processes and predictions, (2) visual representation of data distributions and choice of the appropriate distribution for analysis, and (3) model comparison. The three strategies…

Heterogeneity in meta-analysis is most commonly estimated using a moment-based approach described by DerSimonian and Laird. However, this method has been shown to produce biased estimates. Alternative methods to estimate heterogeneity include the restricted maximum likelihood approach and those proposed by Paule and Mandel, Sidik and Jonkman, and…

This research aimed to develop the virtual learning media of the sacred object artwork by applying the concept of the virtual technology in order to publicize knowledge on the cultural wisdom of the sacred object artwork. It was done by designing and developing the virtual learning media of the sacred object artwork for the virtual presentation.…

This study aims at finding out the effect of peer assessment on the evaluation process of students. The hypothesis underlying this study is that assessment is an integral part of the learning process, which should play an important role in the educational model. The current study will emphasize the importance of using peer assessment as a tool to…

Saudi Arabia is one of the countries that encounter the issue of bilingualism due to the spread of private schools that offer programs in different languages. This research is an attempt to investigate the impact of bilingualism on the creative capabilities (Fluency, Flexibility, Originality, Details) of kindergarten children in Riyadh. It aims at…

This article focuses on timed tests and specifically on whether increased time enhances test performance. Three courses during the Winter 2015 term (quizzes n = 573) and three courses over the Spring 2015 term (quizzes n = 600) comprised this sample. Students were given the same tests, but the experimental group (Spring 2015) was given 50% more…

The pronunciation of regular past tense verbs seems to be difficult for most L2 learners, especially in L2 learners whose first language phonological system is different from the English one. It is predicted that Thai EFL students could encounter difficulties perceiving English coda clusters like the '-ed' ending sounds. For this reason, this…

The Student Growth Objectives are assessments created locally or by commercial educational organizations. The students' scores from the Student Growth Objectives are included in teacher summative evaluation as one of the measures of teacher's effectiveness. The high amplitude of the requirements in teacher evaluation raised a concern of whether…

This research aims to get acquainted with the effectiveness of the active learning strategy in improving the acoustic awareness skills and understanding what is heard by the basic stage students in Jordan by answering the two following questions: This research has been applied to a sample of 60 students from the basic third grade in Al-Ahnaf Ben…

The purpose of this quantitative descriptive comparative study was to investigate and explore the usage of multimedia instructional tools (MMITs) in an integrated business applications course to determine if there was a statistically significant difference in the gain scores between the pretest and posttest scores of high school students who used…

We find statistically significant relationships between changes in wages by occupation and subsequent changes in college majors completed in associated fields. College majors (defined at a detailed level) are most strongly related to wages observed three years earlier, when students were college freshmen. The responses to wages vary depending on…

If Christian schools desire students to achieve higher-level thinking, then the textbooks that teachers use should reflect such thinking. Using Risner's (1987) methodology, raters classified questions from two Christian publishers' fifth grade reading textbooks based on the revised Bloom's taxonomy (Anderson et al., 2001). The questions in the A…

The aim of this research was to establish whether gender and age have an impact on spatial reasoning and its development through the use of 3D modeling. The study was conducted on a sample of 196 children from sixth to ninth grade, of whom 95 represented the experimental group and 101 the control group. The experimental group received 3D modeling…
