Purpose: Sound pressure level (SPL) measurement of voice and speech is often considered a trivial matter, but the measured levels are often reported incorrectly or incompletely, making them difficult to compare among various studies. This article aims at explaining the fundamental principles behind these measurements and providing guidelines to improve their accuracy and reproducibility. Method: Basic information is put together from standards, technical, voice and speech literature, and practical experience of the authors and is explained for nontechnical readers. Results: Variation of SPL with distance, sound level meters and their accuracy, frequency and time weightings, and background noise topics are reviewed. Several calibration procedures for SPL measurements are described for stand-mounted and head-mounted microphones. Conclusions: SPL of voice and speech should be reported together with the mouth-to-microphone distance so that the levels can be related to vocal power. Sound level measurement settings (i.e., frequency weighting and time weighting/averaging) should always be specified. Classified sound level meters should be used to assure measurement accuracy. Head-mounted microphones placed at the proximity of the mouth improve signal-to-noise ratio and can be taken advantage of for voice SPL measurements when calibrated. Background noise levels should be reported besides the sound levels of voice and speech.

In 2 separate studies, we found that college-age students learned more when they collaboratively watched tutorial dialogue-videos than lecture-style monologue-videos. In fact, they can learn as well as the tutees in the dialogue-videos. These results replicate similar findings in the literature showing the advantage of dialogue-videos even when observers watched them individually. However, having the observing students watch collaboratively as dyads provided data to carry out in-depth analyses of their conversations and activities in order to understand why dialogue-videos are superior to monologue-videos. Toward that goal, transcripts of video dialogues and monologues, as well as peer-to-peer conversations of the observing students collected in a prior study, were analyzed using the ICAP (interactive, constructive, active, passive) framework as a lens. Three sets of analyses were carried out. The 1st set focused on the content of the videos in terms of the tutors' and the tutees' moves. The 2nd set focused on the activities and behaviors of the collaboratively observing dyads. The 3rd set focused on the role of the tutees in the dialogue-videos in eliciting constructive and interactive engagement from the observing students. Our analyses suggest that dialogue-videos naturally elicited more constructive and interactive engagement behaviors from the observers than the monologue-videos, which in turn mediated the observers' own learning.

Mentorship, consisting of its official and unofficial forms, transforms medical trainees into competent and well-rounded physicians. In this commentary, we reflected on existing mentorship programs at the McMaster School of Medicine, highlighted lessons from a new peer-based mentorship program, and revisited the benefits of integrating diverse mentorship styles to enhance medical education.

This paper examines the UK government’s main intervention in education during and after the COVID crisis—the National Tutoring Programme (NTP)—which operated in England from 2020–24. It involves a truncated genealogy of the NTP which shows how, when learning loss emerged as a key policy problem, the private sector was promoted as the main policy solution. We trace the evolution and decline of the NTP in response to schools’ experiences and needs. We also conduct a network analysis of the final iteration of the NTP and suggest that although it can be seen as a policy failure, it set a significant precedent in the extent to which the private sector became imbricated into the machinations of governance. We use the construct of heterarchical governance to argue that the NTP saw the establishment of a mezzanine level of governance which saw the involvement of the global education industry, with its concomitant neoliberal imaginary of education, embedded at a powerful level of the policy process. This raises questions about how privatisation might be conceptualised and articulated as well as raising concerns about the capacity for global actors to access and shape national education systems, notably during times of crisis.   

Background: With respect to the clinical criteria for diagnosing \"childhood apraxia of speech\" (commonly defined as a disorder of speech motor planning and/or programming), research has made important progress in recent years. Three segmental and suprasegmental speech characteristics--error inconsistency, lengthened and disrupted coarticulation, and inappropriate prosody--have gained wide acceptance in the literature for purposes of participant selection. However, little research has sought to empirically test the diagnostic validity of these features. One major obstacle to such empirical study is the fact that none of these features is stated in operationalized terms. Purpose: This tutorial provides a structured overview of perceptual, acoustic, and articulatory measurement procedures that have been used or could be used to operationalize and assess these 3 core characteristics. Methodological details are reviewed for each procedure, along with a short overview of research results reported in the literature. Conclusion: The 3 types of measurement procedures should be seen as complementary. Some characteristics are better suited to be described at the perceptual level (especially phonemic errors and prosody), others at the acoustic level (especially phonetic distortions, coarticulation, and prosody), and still others at the kinematic level (especially coarticulation, stability, and gestural coordination). The type of data collected determines, to a large extent, the interpretation that can be given regarding the underlying deficit. Comprehensive studies are needed that include more than 1 diagnostic feature and more than 1 type of measurement procedure.

Education researchers often encounter scenarios where an abrupt policy change occurs within or across jurisdictions or populations that affect key student outcomes. Difference-in-differences is a research design analysts can use to estimate causal effects of these “natural experiments.” This article introduces education researchers to the difference-in-differences approach. We provide an overview of the standard two-by-two design, which examines changes in outcomes over time between a treated and an unaffected group. Then, we discuss the key assumptions and threats to validity that researchers must address to have maximum confidence in their results. We also discuss commonly used alternative specifications that provide researchers with a more nuanced approach to estimating policy effects. Throughout the paper, we illustrate the difference-in-differences approach using the example of the implementation of an after-school tutoring program to increase economically disadvantaged students’ academic performance. In supplementary material, we provide Stata code to help assist researchers adapt the approach to their own scholarship.

Background Geopolitical and socioeconomic challenges limit faculty development and clinical teaching in Palestine and many other developing countries. The first, and still only, Family Medicine (FM) residency program is a four-year program based out of An-Najah University in the West Bank. Training in primary care clinics occurs in the final two years and there are many challenges to adequate supervision in the clinical setting that were exacerbated during the pandemic. To improve the readiness for practice skills of 13 Palestinian FM residents a three-month tutorial program was organized in 2020. A nongovernmental organization (NGO) that has worked to support Family Medicine development in the region engaged experienced British and American General Practitioners trained as tutors to offer online tutorials. We examined the program as a case study to understand the factors that facilitated or impaired a positive virtual learning environment in a middle/low income country. Methods The tutors and residents were divided into groups and met virtually between June and September 2020. Evaluations and session reports collected during the program, the text of an online chat, and responses to an online survey two years later were collected. Using thematic analysis techniques, we evaluated the value for the residents at the time and two years later and identified factors that facilitated or impaired a positive virtual learning environment. Results Themes of knowledge, skills, attitudes, cultural disconnects, and tutorial logistics emerged. The group with the most stable tutor pairing, including one Arabic-speaker familiar with the context, was the most engaged. The all-female group formed a chat group to share real-time case questions during clinical practice and focused on skills (e.g. conducting a thorough medication review) and attitudes (e.g. open to sharing and discussing uncertainties). Other groups were less cohesive. Conclusions Transnational tutorials that focused on clinical thinking and decision-making skills were most successful when the tutorial pair was stable, offered familiarity with the language and addressed cultural differences. Intrinsic factors such as lacking the motivation to participate and extrinsic factors such as unstable internet and rolling electric cuts, and clinical structures that made applying new skills challenging were more difficult to address but must be considered.

This article reviews research on the achievement outcomes of elementary mathematics programs; 87 rigorous experimental studies evaluated 66 programs in grades K–5. Programs were organized in six categories. Particularly positive outcomes were found for tutoring programs (effect size [ES] = +0.20, k = 22). Positive outcomes were also seen in studies focused on professional development for classroom organization and management (e.g., cooperative learning; ES = +0.19, k = 7). Professional development approaches focused on helping teachers gain in understanding of mathematics content and pedagogy had little impact on student achievement. Professional development intended to help in the adoption of new curricula had a small but significant impact for traditional (nondigital) curricula (ES = +0.12, k = 7), but not for digital curricula. Traditional and digital curricula with limited professional development, as well as benchmark assessment programs, found few positive effects.

PurposeFace-to-face tutorial sessions remain an integral part of the delivery mode of distance education in Ghana. It is sometimes used as the sole mode of delivery of educational content in some distance education institutions. This study, therefore, investigated the interconnectedness of elements of face-to-face tutorials among distance education students.Design/methodology/approachThe study adopted the positivist approach and used descriptive research as a design. Simple random and stratified sampling techniques were used, and a sample of 1,491 students was drawn from a population of 44,001 across all regions of Ghana. Data were collected with a self-administered questionnaire and analysed with descriptive and inferential statistics.FindingsThe study found that collaborative learning, counselling, self-directed learning, motivation and critical thinking had strong interrelationships as elements of face-to-face tutorials.Research limitations/implicationsThis quantitative study was limited to the views of students on the elements of face-to-face tutorials. It was envisaged, however, that the views of the tutors and administrators who conducted the face-to-face tutorials could have enriched the findings of the study. In addition, adopting a mixed design approach where both qualitative and quantitative data were collected from the participants could have given an in-depth and enriched perspective of the current study.Practical implicationsManagement of distance education institutions need to focus on these important elements and their inter-relationships as they might lead to improved academic and social progress among students. In addition, institutions must also organise orientations and seminars for course facilitators and new students on the need to develop commitments towards the elements of face-to-face tutorials as requirement so as to succeed on their course of study.Originality/valueThis is a novel approach that will help improve the understanding of students on the importance of the activities they engage in during face-to-face tutorials. It would also help managers of institutions using face-to-face tutorials to focus on these important elements that might lead to improved academic work among students.

The adoption of active learning instructional practices in college science, technology, engineering, and mathematics (STEM) courses has been shown to result in improvements in student learning, contribute to increased retention rates, and reduce the achievement gap among different student populations. Descriptions of active learning strategies have been reported in other disciplines; however, the research literature that documents the success of these strategies may be unfamiliar to many geoscience instructors. This literature review seeks to serve as a bridge that connects the reflective practitioner, the research literature on instructional strategies, and the network of community resources available to the geoscience educator. We review the characteristics of 11 active learning strategies and weigh the evidence that these strategies improve student learning. Furthermore, we analyze the utility of these strategies in the context of their use in geoscience classrooms. We seek to provide geoscience instructors with a decision-making guide and evidence-based recommendations that they can use to select and implement active learning strategies that have the potential to enhance undergraduate learning experiences in geoscience courses.
