This NCEE Technical Methods report examines how to address the problem of missing data in the analysis of data in Randomized Controlled Trials (RCTs) of educational interventions, with a particular focus on the common educational situation in which groups of students such as entire classrooms or schools are randomized. Missing outcome data are a…

Background: The area of research aimed for a more efficient e-learning is slowly widening from purely technical to the areas of psychology, didactics and methodology. The question is whether the text or background color influence the efficiency of memory, i.e. learning. If the answer to that question is positive, then another question arises which…

The "Value-Added School Review (VSR)" is an analytical model designed to assist schools in identifying and addressing opportunities for school improvement. The model works best when it is focused purposefully on students and the student learning outcomes as defined in the "Guide to Education". It complements the processes…

The study sought to understand adolescents' perceived career challenges and needs in a disadvantaged context using the Social Cognitive Career Theory (SCCT). A qualitative research design based on semi-structured interviews was conducted with 12 Grade 9 and Grade 10 learners from a disadvantaged background. The results of the study indicated a…

Collaborating with universities in Hong Kong, Finland, the United Kingdom and Australia the research project outlined in this paper takes up one of the key initial findings related to the importance of children's online spaces away from school. The project brings together complementary strengths from each partner nation to assist our mutual need…

This paper describes one phase of an investigation into the possible existence of gender interactions in one-to-one instrumental music lessons. In order to provide a preliminary sketch-map of a hitherto unexplored field, the mixed methods research design used a combination of three strands: (1) questionnaires to teachers and pupils; (2)…

In this study, the different types of research designs used to assess the impact of prerequisite courses are presented. Supported by an in-depth literature review, the challenges that are faced in the assessment of the impact of prerequisites, from statistical to political, are identified and their pitfalls are pointed out. In particular, the…

The present meta-analysis examines the effect of grade retention on academic outcomes and investigates systemic sources of variability in effect sizes. Using multilevel modeling (MLM), the authors investigate characteristics of 207 effect sizes across 22 studies published between 1990 and 2007 at two levels: the study (between) and individual…

The purpose of this study was to empirically test the posit that students who participated in a contextualized, mathematics-enhanced high school agricultural power and technology (APT) curriculum and aligned instructional approach would not differ significantly (p less than 0.05) in their technical competence from students who participated in the…

Models of a psychological process can be difficult to discriminate experimentally because it is not easy to determine the values of the critical design variables (e.g., presentation schedule, stimulus structure) that will be most informative in differentiating them. Recent developments in sampling-based search methods in statistics make it…

Background/Context: Much research is being done on Turkish immigrants and their children in Germany and the Netherlands, but almost always from a national perspective. To compare the situation, for example, regarding educational outcomes across the two countries has proved to be very difficult because of different sets, selection criteria, and…

In recent years, the interest grew in research on measuring the "quality of life" (QOL) in cities. This interest comes from the success QOL measurement achieved in understanding communities' needs, tracking changes in different aspects of life and assessing the most desired types of future development among citizens. This research…

We analyse the origin and development of an Experimental Design course which has been taught in several faculties of the Universidad de la Republica and other institutions in Uruguay, over a 10-year period. At the end of the course, students were assessed by carrying out individual work projects on real-life problems, which was innovative for…

This study examines individual, social, and contextual correlates of anxiety sensitivity among African American adolescents living in public housing. The study also reports prevalence of anxiety sensitivity among this population of youth. Participants included 238 African American adolescents (mean age = 15.6) living in three public housing…

D'Eon et al. concluded that change in performance self-assessment means from before to after a workshop can detect workshop success in their and other situations. In this commentary, their recommendation is refuted by showing that (a) self-assessments with balanced over- and underestimations are still biased and should not be used to evaluate…
