A Systematic Literature Review of Empiricism and Norms of Reporting in Computing Education Research Literature

Context. Computing Education Research (CER) is critical to help the computing education community and policy makers support the increasing population of students who need to learn computing skills for future careers. For a community to systematically advance knowledge about a topic, the members must be able to understand published work thoroughly enough to perform replications, conduct meta-analyses, and build theories. There is a need to understand whether published research allows the CER community to systematically advance knowledge and build theories. Objectives. The goal of this study is to characterize the reporting of empiricism in Computing Education Research literature by identifying whether publications include content necessary for researchers to perform replications, meta-analyses, and theory building. We answer three research questions related to this goal: (RQ1) What percentage of papers in CER venues have some form of empirical evaluation? (RQ2) Of the papers that have empirical evaluation, what are the characteristics of the empirical evaluation? (RQ3) Of the papers that have empirical evaluation, do they follow norms (both for inclusion and for labeling of information needed for replication, meta-analysis, and, eventually, theory-building) for reporting empirical work? Methods. We conducted a systematic literature review of the 2014 and 2015 proceedings or issues of five CER venues: Technical Symposium on Computer Science Education (SIGCSE TS), International Symposium on Computing Education Research (ICER), Conference on Innovation and Technology in Computer Science Education (ITiCSE), ACM Transactions on Computing Education (TOCE), and Computer Science Education (CSE). We developed and applied the CER Empiricism Assessment Rubric to the 427 papers accepted and published at these venues over 2014 and 2015. Two people evaluated each paper using the Base Rubric for characterizing the paper. An individual person applied the other rubrics to characterize the norms of reporting, as appropriate for the paper type. Any discrepancies or questions were discussed between multiple reviewers to resolve. Results. We found that over 80% of papers accepted across all five venues had some form of empirical evaluation. Quantitative evaluation methods were the most frequently reported. Papers most frequently reported results on interventions around pedagogical techniques, curriculum, community, or tools. There was a split in papers that had some type of comparison between an intervention and some other dataset or baseline. Most papers reported related work, following the expectations for doing so in the SIGCSE and CER community. However, many papers were lacking properly reported research objectives, goals, research questions, or hypotheses; description of participants; study design; data collection; and threats to validity. These results align with prior surveys of the CER literature. Conclusions. CER authors are contributing empirical results to the literature; however, not all norms for reporting are met. We encourage authors to provide clear, labeled details about their work so readers can use the study methodologies and results for replications and meta-analyses. As our community grows, our reporting of CER should mature to help establish computing education theory to support the next generation of computing learners.

Challenging boundaries to expand frontiers in gender and policy studies

Gender and policy studies needs to face challenges and cross boundaries if the discipline is to develop. This article argues that gender and policy studies needs to explicitly foreground the centrality of politics – the analysis of power – in approaching policy. The discipline confronts boundaries in relation to inclusivity, diversity and relevance. Inclusive gender equality demands challenging the hegemonising and marginalising boundaries in the field, which contributes to its relevance by placing politics and power centre stage. Openness to the diversity of gender and policy approaches, a more systematic and thoughtful application of intersectionality, cooperation with LGBTQI+, critical race studies and normative political theory provide opportunities to challenge boundaries and advance knowledge. We argue that explicit reflexivity about power dynamics and knowledge production, employing a plurality of approaches, will better equip the discipline to navigate major challenges and crises, and offer more nuanced democratic and egalitarian societal contributions.

Reflective Practice in Anesthesia Clinical Teaching

BackgroundReflective practice is an essential aspect of knowledge generation for professional practice. By reflecting on action, professionals learn to improve their practices. Through processes of reflection, practitioners participate in a dialogue between theory and practice. Even though reflective practice is an important approach for learning from experience, its place remains unclear in anesthesia clinical education as well as anesthesia practice in a broad sense.AimThe aim of this paper was to examine the affordances of reflective practice in anesthesia clinical education.MethodsTwo cases, illustrating critical incidents in the anesthesia clinical teaching environment, were examined to consider how incorporating reflective practice into clinical education can advance knowledge generation in the field.FindingsThe two cases studies show how reflective practice can contribute to experiential learning, particularly through reflection on critical incidents.ConclusionReflective practice can help bridge the gap between theoretical knowledge and practice in anesthesia education and practice.Rwanda J Med Health Sci 2021;4(3):406-411

The present paper has described a comparatively new application of the neural network in the field of spatial interpolation. Neural network interpolation models are developed for both maximum and minimum temperatures for all the twelve months. The model utilizes geographical information like latitude, longitude and elevation as inputs to generate normal maximum and minimum temperatures at a place. The performances of the models are compared with the other commonly used method for spatial interpolation.

New Frontiers in Functional and Molecular Imaging of the Acutely Injured Lung: Pathophysiological Insights and Research Applications

This review focuses on the advances in the understanding of the pathophysiology of ventilator-induced and acute lung injury that have been afforded by technological development of imaging methods over the last decades. Examples of such advances include the establishment of regional lung mechanical strain as a determinant of ventilator-induced lung injury, the relationship between alveolar recruitment and overdistension, the regional vs. diffuse nature of pulmonary involvement in acute respiratory distress syndrome (ARDS), the identification of the physiological determinants of the response to recruitment interventions, and the pathophysiological significance of metabolic alterations in the acutely injured lung. Taken together, these advances portray multimodality imaging as the next frontier to both advance knowledge of the pathophysiology of these conditions and to tailor treatment to the individual patient’s condition.

Sex Differences in Substance Use Disorders: A Neurobiological Perspective

Clinical studies provide fundamental knowledge of substance use behaviors (substance of abuse, patterns of use, relapse rates). The combination of neuroimaging approaches reveal correlation between substance use disorder (SUD) and changes in neural structure, function, and neurotransmission. Here, we review these advances, placing special emphasis on sex specific findings from structural neuroimaging studies of those dependent on alcohol, nicotine, cannabis, psychostimulants, or opioids. Recent clinical studies in SUD analyzing sex differences reveal neurobiological changes that are differentially impacted in common reward processing regions such as the striatum, hippocampus, amygdala, insula, and corpus collosum. We reflect on the contribution of sex hormones, period of drug use and abstinence, and the potential impact of these factors on the interpretation of the reported findings. With the overall recognition that SUD impacts the brains of females and males differentially, it is of fundamental importance that future research is designed with sex as a variable of study in this field. Improved understanding of neurobiological changes in males and females in SUD will advance knowledge underlying sex-specific susceptibility and the neurobiological impact in these disorders. Together these findings will inform future treatments that are tailor designed for improved efficacy in females and males with SUD.

Machinability investigation of polymer/GNP nanocomposites in micro-milling

Nanoparticles such as graphene have been added to various polymer matrices to enhance the mechanical, thermal, and electrical properties of polymer materials that require complex designs on a microscopic scale. Micro-machining is used to process these nanocomposite materials to achieve high surface quality and dimensional accuracy while maintaining high productivity. In this study, a systematic micro-milling experiment was performed on polymer/graphene nanoplatelet (GNP) nanocomposites to advance knowledge of the micro-machinability of these materials. It evaluates the effect of the addition of 0.1wt% GNP nanoparticles on machined surface morphology, chip formation, cutting forces, and tool wear. It is found that the addition of GNP nanoparticles changes the slot edge formation mode from burring mode to chipping mode.

Judging What Others Enjoy: Desirability and Observability of Interests

Interests guide major life decisions such as choosing a career path, yet little is known about the subjective characteristics of individual differences in interests. Prior research on personality traits has demonstrated that subjective trait perceptions influence the validity and reliability of personality assessments. The current work expands the study of these subjective characteristics to individual differences in interests. Desirability and observability were assessed among 13 constructs: person orientation, thing orientation, RIASEC career interests, and Big Five traits. Judgments of interest dimensions varied considerably, with socially-related interests rated more desirable than thing-related interests. Some career-related interests were low in observability, and thus may be susceptible to being overlooked or categorized inaccurately. The patterns observed in interest characteristics were comparable to patterns in career choice hit rates, occupational prestige, and self-other convergence. The findings advance knowledge of differences between interest dimensions and suggest that subjective perceptions should be considered in interest assessment.

Introduction: The makers and the made

Academic disciplines are a help and a hindrance. While they advance knowledge by focusing disciplinarians on a coherent set of related issues, those same boundaries that define and focus, also delimit and inhibit expansion of universal knowledge for the broad benefit of humanity. Such are Communication Design and Visual Anthropology.
