The present review describes a meta-analysis of findings from 50 controlled evaluations of intelligent computer tutoring systems. The median effect of intelligent tutoring in the 50 evaluations was to raise test scores 0.66 standard deviations over conventional levels, or from the 50th to the 75th percentile. However, the amount of improvement found in an evaluation depended to a great extent on whether improvement was measured on locally developed or standardized tests, suggesting that alignment of test and instructional objectives is a critical determinant of evaluation results.

In this article, the authors argue Experience-sampling methods (ESM) can be particularly enriching for education research by enabling us to ask new and interesting questions about how students, teachers, and school leaders engage with education as they are living their lives and thus help us to better understand how education contexts shape learning and other outcomes. They highlight the value of these approaches for addressing new and exciting questions they may help education researchers to answer as they allow us to uncover experience in new ways.

Meta-Analysis With Complex Research Designs: Dealing With Dependence From Multiple Measures and Multiple Group Comparisons
This article summarizes the different approaches to handling dependence that have been advocated by methodologists. The authors present a case study using effect sizes from a recent meta-analysis of reading interventions, in order to compare the results obtained from different approaches to dealing with dependence. The results show that mean effect sizes and variance estimates were found to be similar.However, estimates of indexes of heterogeneity varied.

The authors describe the affordances of a stance of reciprocity, illustrating the contours of the component in recruitment, participation, analysis, and presentation. They ask: How do truth traditions support reciprocity? How do we authentically reciprocate participants’ efforts throughout the research process? And finally, how might qualitative work embrace reciprocity and lead education research to a broader conceptualization of evidence, one that expands the transformative potential of our collective work?

In this article, the authors review the basic features of Design-based research (DBR). The authors describe the trends toward increasing its use, and highlight and analyze the most cited articles that focus on DBR in education. The authors conclude that DBR is being utilized increasingly in educational contexts and especially those in the United States. It seems to be especially attractive for use in K–12 contexts and with technological interventions. The increasing number of studies reported suggests that researchers and graduate students are finding ways to meet the time demands of multiple iteration studies.

Teacher attrition threatens validity in research studies. In this article, the authors examine the threat of participant attrition as an example of the types of problems researchers face. The authors found that teachers left because of changes in teaching assignments, institutional challenges, and personal challenges.

Studying the Impact of the Lesson Analysis Framework on Preservice Teachers’ Abilities to Reflect on Videos of Classroom Teaching
This study investigates the impact of the Lesson Analysis Framework (LAF) on preservice teachers’ abilities to analyze lessons through an experimental design. The intervention was implemented as part of a course in the teacher preparation program for secondary teaching at a large public university in Italy. The participants were randomly assigned to LAF group and Teaching Rating Framework (TRF) group. The findings revealed that participants who used the LAF as a lens for reflecting on a videotaped lesson during an intervention improved their unprompted analysis of a novel lesson after the intervention, whereas the reflections of participants who used an alternative framework, the TRF, did not change over time.

Attention has been directed toward extended school time as a measure to improve academic achievement. past reviewers have argued that any positive relation between allocated time and achievement is tentative and instructional quality needs to be addressed first. After a comprehensive search of the literature, 15 empirical studies of various designs conducted since 1985 were found. The findings suggest that extending school time can be an effective way to support student learning.

Methodology in Our Education Research Culture: Toward a Stronger Collective Quantitative Proficiency
The goal of this article is to examine how quantitative methods are used in the literature and taught in doctoral programs. Evidence points to deficiencies in quantitative training and application in several areas: (a) methodological reporting problems, (b) researcher misconceptions and inaccuracies, (c) overreliance on traditional methods, and (d) a lack of coverage of modern advances. An argument is made that a culture supportive of quantitative methods is not consistently available to many applied education researchers.

Professional Development for Information Communication Technology Integration: Identifying and Supporting a Community of Practice through Design-Based Research
Research suggests effective classroom ICT integration occurs through needs-based, collaborative professional development (Chandra-Handa, 2001; Cuttance, 2001; Figg, 2000; Gibson, Oberg, & Pelz, 1999; Gross, 2000; Haughey, 2002). A community of practice (CoP) (Wenger, 1998; Wenger, McDermott, & Snyder, 2002) can be an effective mode of such collaborative professional development. Principles for this research approach are discussed and address the membership of a CoP and teacher/researcher ownership of research goals and design.
