Reflecting recent knowledge and developments in the field, this very practical, easy-to-use guide emphasizes learning how to do case study research--from the first step of deciding whether a case study is the way to go to the last step of verifying and confirming findings before disseminating them. The authors show students how to determine an…

"A priori" power analyses allow researchers to estimate the number of participants needed to detect any effects of an intervention. However, power analyses are only as valid as the parameter estimates used. Effect sizes vary greatly depending on several study characteristics, including the nature of the intervention, the developer of the…

The published literature often underrepresents studies that do not find evidence for a treatment effect; this is often called "publication bias." Literature reviews that fail to include such studies may overestimate the size of an effect. Only a few studies have examined publication bias in single-case design (SCD) research, but those…

Students with significant intellectual and developmental disabilities deserve access to instruction on academic skills in addition to functional skills. Many teachers, however, report challenges with identifying appropriate evidence-based practices to teach academics to these students. The purpose of this systematic review was to summarize and…

There is much debate over the number of interviews needed to reach data saturation for themes and metathemes in qualitative research. The primary purpose of this study is to determine the number of interviews needed to reach data saturation for metathemes in multisited and cross-cultural research. The analysis is based on a cross-cultural study on…

A key consideration in planning studies of community-based HIV education programs is identifying a sample size large enough to ensure a reasonable probability of detecting program effects if they exist. Sufficient sample sizes for community- or group-based designs are proportional to the correlation or similarity of individuals within communities.…

This research was motivated by several studies which show that students have difficulties in understanding the material ratio, wherein one contributing factor is the lack of ability in proportional reasoning. The purpose of this study is to produce a trajectory of learning to help students develop abilities in comparison reasoning. Solution…

Academic publications provide insights into a discipline's history, knowledge base, and research norms, and thus analyzing publication activity provides learning about the field of study. To learn more about the field of adult and continuing education, this study used content analysis to examine 10 years of "Adult Learning" from 2006…

Stakeholders in STEM education have called for integrating engineering content knowledge into STEM-content classrooms. To answer the call, stakeholders in science education announced a new framework, Next Generation Science Standards, which focuses on the integration of science and engineering in K-12 science education. However, research indicates…

With a view to enhancing the entrepreneurial activity of universities, the authors explore the concepts and features of the "experimental lab", presenting it as an effective means of supporting entrepreneurial training programmes and helping students to turn ideas into actual start-ups. In this context, the term experimental lab refers…

The study investigated students' access to and utilization of some learning resources in selected public and private universities in southwest Nigeria. Stratified random sampling technique was used to select 585 (295 public and 290 private) students from 12 (six public and six private) universities in southwest Nigeria. Two instruments--Cost and…

The rise of online course enrollments in higher education has highlighted the need to establish and validate effective online instructional strategies focused on improving learning outcomes and affective responses towards instruction. One such strategy, group-based context personalization, frames instructional materials within contexts relevant to…

Baeysian Network Meta-Analysis represents a rather unique challenge in assessing the quality of included studies. Prior efforts to synthesize computer based scaffolding are in need of a closer examination of research quality. This study examines two quality metrics for meta-analysis, study design, and risk of bias (Higgins et al., 2011). Lower…

School practitioners and educators are frequently challenged by the diverse and pervasive academic and behavioral needs of children at risk for and with attention-deficit hyperactivity disorder (ADHD). This paper examines the outcome literature on self-regulated learning (SRL) interventions for youth with ADHD by systematically reviewing the key…

Using disciplinary exclusions, such as office referrals, suspensions, and expulsions, has been the subject of significant concern related to student and family civil rights, school policy, and negative impact on short- and long-term outcomes for students. Embedded in this phenomenon is the documentation of significant and persistent…
