As evidence becomes increasingly important in educational policy, it is essential to understand how research design might contribute to reported effect sizes in experiments evaluating educational programs. A total of 645 studies from 12 recent reviews of evaluations of preschool, reading, mathematics, and science programs were studied. Effect sizes were roughly twice as large for published articles, small-scale trials, and experimenter-made measures, compared to unpublished documents, large-scale studies, and independent measures, respectively. Effect sizes were significantly higher in quasiexperiments than in randomized experiments. Excluding tutoring studies, there were no significant differences in effect sizes between elementary and middle/high studies. Regression analyses found that effects of all factors maintained after controlling for all other factors. Explanations for the effects of methodological features on effect sizes are discussed, as are implications for evidence-based policy.

In this technical comment, we argue that Morgan et al.'s claim that there is no minority overrepresentation in special education is in error due to (a) sampling considerations, (b) inadequate support from previous and current analyses, and (c) their failure to consider the complexities of special education disproportionality.

Purpose: Patients with voice problems commonly report increased vocal effort, regardless of the underlying pathophysiology. Previous studies investigating vocal effort and voice production have used a range of methods to quantify vocal effort. The goals of the current study were to use the Borg CR100 effort scale to (a) demonstrate the relation between vocal intensity or vocal level (dB) and tasked vocal effort goals and (b) investigate the repeated measure reliability of vocal level at tasked effort level goals. Method: Three types of speech (automatic, read, and structured spontaneous) were elicited at four vocal effort level goals on the Borg CR100 scale (2, 13, 25, and 50) from 20 participants (10 females and 10 males). Results: Participants' vocal level reliably changed approximately 5 dB between the elicited effort level goals; this difference was statistically significant and repeatable. Biological females produced a voice with consistently less intensity for a vocal effort level goal compared to biological males. Conclusions: The results indicate the utility of the Borg CR100 in tracking effort in voice production that is repeatable with respect to vocal level (dB). Future research will investigate other metrics of voice production with the goal of understanding the mechanisms underlying vocal effort and the external environmental influences on the perception of vocal effort.

Studies on physics identity are appearing more frequently and often responding to increased awareness of the underrepresentation of students of color in physics. In our broader research, we focus our efforts on understanding how racial identity and physics identity are negotiated throughout the experiences of Black physicists. In this paper, we present a Critical Physics Identity framework that can be used to examine racialized physics identity and demonstrate the utility of this framework by analyzing interviews with four physicists. Our framework draws from prior constructs of physics identity and racialized identity and provides operational definitions of six interacting dimensions. In this paper, we present the operationalized constructs, demonstrate how we use these constructs to code narrative data, as well as outline three methods of analysis that may be applied to study systems and structures and their influences on the experiences of Black students.

This meta-analysis examined the influence of attributes related to the implementation of learning strategy instruction interventions on students' academic performance, and also examined how the attributes related to the method of testing the intervention effects affected the actual effects measured. Using metaregression, we analyzed the influence of the subject domain in which the intervention was implemented, the implementer, its duration and intensity, student cooperation, and research method aspects (including measurement instrument). Most attributes moderated the intervention effect. Using forward regression analysis, we only needed four attributes to obtain the best model, however, This analysis showed that the intervention effect was lower when a standardized test was used for evaluation instead of an unstandardized test. Interventions implemented by assistants or researchers were more effective than those implemented by teachers or using computers. Cooperation had a negative, and session duration a positive, contribution. Together, these attributes explained 63.2% of the variance in effect, which stresses the importance of emphasizing not only the instructional focus of an intervention but also its other attributes.

The hospital setting may be especially difficult for pediatric patients on the autism spectrum and their families compared to those not on the spectrum. Child life specialists are healthcare professionals specifically trained to support parents and their children and help prepare them for hospital procedures. Because of this specialized skill set, these professionals likely have a wealth of expertise to share relevant to caring for autistic patients. This study aimed to understand 21 child life specialists’ experiences working with patients on the spectrum. Our findings highlighted the following themes: Parents are the Experts, Proactive and Individualized Care, Disclosure, and Hospital-Wide Suggestions to Improve Patient Care. We discuss the practice implications of these findings on the healthcare experiences of pediatric patients on the spectrum.

Numerous methods are available to assess physical activity (PA) but systematic observation (SO) excels in being able to provide contextually rich data on the setting in which the activity occurs. As SO is particularly useful for determining how activity is influenced by the immediate physical and social environments, its use is becoming more popular. Observation tools have the advantages of flexibility, high internal validity, low inference, and low participant burden, while their disadvantages include the need for careful observer training and recalibration, inaccessibility to certain environments, and potential participant reactivity. There is a need for both scientists and practitioners to have additional information on observation techniques and systems relative to making environmental and policy decisions about PA, and in this article, we describe concepts and identify questions related to using SO in researching PA behavior. We present 10 general questions in 3 sections, including those related to: (a) ensuring data accuracy through the selection of the most appropriate methodological protocols; (b) investigating PA in school settings, including physical education, recess, and other programs; and (c) investigating PA in community settings (e.g., parks, recreation centers, youth and adult sport programs) and homes.

Outcome-reporting bias occurs when primary studies do not include information about all outcomes measured in a study. When studies omit findings on important measures, efforts to synthesize the research using systematic review techniques will be biased and interpretations of individual studies will be incomplete. Outcome-reporting bias has been well documented in medicine and has been shown to lead to inaccurate assessments of the effects of medical treatments and, in some cases, to omission of reports of harms. This study examines outcome-reporting bias in educational research by comparing the reports of educational interventions from dissertations to their published versions. We find that nonsignificant outcomes were 30% more likely to be omitted from a published study than statistically significant ones.

Purpose: The purpose of this study was to investigate whether there are indications of gender-related voice problems in our transmasculine participants and to analyze how discrepancies between participant self-evaluations and researcher-led examinations can be best negotiated to ensure a participant-centered interpretation. Method: We conducted a participant-centered mixed-methods study combining qualitative content analyses of semistructured interviews, acoustical voice analyses, and an examination of gender attributions to voice. Fourteen German-speaking transmasculine people, 14 cisfemale control persons, and 7 cismale control persons participated. The data were examined for indications of gender-related voice problems pertaining to vocal gender presentation and gender attribution to voice received from others. Results: Eleven participants (79%) presented with indications of gender-related voice problems. Problems included dissatisfaction with gender-related voice features, difficulties with control of vocal gender presentation, and mismatch between desired gender attribution and gender attributions received from others. Discrepancies between participant self-evaluations and researcher-led examinations were observed in a number of cases. Conclusion: Transmasculine speakers may experience a range of gender-related voice problems. Research and clinical practice with transmasculine people need to be adapted to better match the diversity of the population and the complexity of the processes that shape the production of speaker vocal gender in interaction.

Background Interdisciplinary collaboration among academic pharmacists is crucial for enhancing scientific research, discovering new drugs and modifying existing ones, besides solving pharmaceutical problems. This study aimed to explore the perception and experience of academic pharmacists regarding research collaboration. Methods A qualitative study through one-to-one face-to-face interviews with faculty members at the University of Baghdad/College of Pharmacy was conducted from May to July/2023. Purposive and convenience strategies were used to enroll study participants. Thematic-analysis approach was used to analyze the data. Results Twenty-four faculty members were interviewed. Most participants were female with ≥ 10 years of academic experience. Five themes emerged from the obtained data. The first theme, entitled the collaborative research was conducted at three different levels: college, national, and to a lesser extent, international. The second theme was facilitators of collaborative research. This theme includes two subthemes the reasons behind research collaboration and the encouraging characteristics of the researcher. Seeking scientific and technical support were the main reported reasons behind domestic collaborations, while supervising postgraduate students was the main reason for international collaborations. The third theme was the barriers to collaborative research. The complicated-university laws, besides limited-resources & funds, were barriers to collaborative research. Academic workload was the main challenge for domestic collaborations, whereas poor professional-networking was the main challenge for international collaborations. Ethical challenge in collaborative research was the fourth study theme. The last theme was the recommendations to improve future research collaboration. In this regard, most participants recommended enhancing academics’ research-skills, increasing research funding, and simplifying regulatory issues to improve collaborative research. Conclusion Research collaborations occur at the domestic and, to a limited extent, at the international level. Academic workload, shortage of resources, and complicated university regulations are the main challenges for research collaborations. Enhancing research-skills, increasing research funding, and simplifying university regulations can improve research collaborations.
