Examining Mentor Perception of Competence in an Academic Peer Mentoring Program.

Peer mentoring programs can be a valuable support mechanism for new faculty transitioning from clinical practice to academia. Mentors play a crucial role in this process. This study described mentors' perceived competence in 21 areas of the mentor role and their experiences as mentors following the first year of a structured peer mentoring program. This study employed a mixed-methods approach, using the Mentoring Competency Assessment-21 alongside open-ended questions. These instruments were electronically administered to a convenience sample consisting of eight mentors with varying experience ranging from 2 to 16 years in the nursing program at a mid-sized university, following an intentional first-year peer mentoring program. The highest-performing items were "Establishing a relationship based on trust" (M 6.50, SD 0.53), "Considering how personal and professional differences may impact expectations" (M 6.25, 0.83), and "Acknowledging your mentee's professional contributions" (M 6.13, SD 0.99). The lowest scores were focused on estimating scientific knowledge and scholarly productivity. Responses to the Mentoring Competency Assessment-21 indicated that mentors felt at least moderately competent in the various aspects of the faculty mentor role. Mentors valued the professional development and supporting materials provided by the development team. An identified area for improvement was the support provided to assist the mentees' scholarly development. This study underscores the importance of supportive materials, such as handbooks and regular communication, in fostering mentor competence and facilitating successful nursing faculty peer mentoring programs. Future research implications include assessment of mentor competence by mentees and long-term follow-up of program outcomes.

Enhancing anatomy comprehension through competency-specific formative assessments: A study on the effectiveness of pre and post lecture multiple-choice questions in CBME

Modern medical education was required to include clear, tailored and regular formative assessments, especially for Millennials. Competency-Based Medical Education (CBME) emphasized the objective assessment of anatomical competencies. Question-answer and viva-voce tests were considered subjective and resource-intensive. This research was conducted to examine how competency-specific formative assessments using multiple-choice questions and photos before and after competency-based medical lectures improved anatomy comprehension.: The research involved 150 first-year MBBS students who were enrolled in online anatomy courses. Competency-specific, picture-based, clinical scenario-based and multiple-choice pre-questionnaires were distributed. The questions were reviewed and attempted by students before attending the theory classes. Lecture classes were conducted according to the curriculum and competencies of the National Medical Council. After the lecture, the questions and answers were reviewed and a feedback questionnaire was administered. The feedback survey included Likert scale responses and open-ended questions to gauge students' opinions on the teaching and learning methodology.: It was observed that the method was effective, stimulating curiosity, motivation and engagement. Participants expressed that the approach facilitated memorization, imparted clinical knowledge and reinforced theory. Clinical scenario-based multiple-choice questions were found to enhance memory, spark interest and improve understanding of anatomy's clinical relevance. Students believed that this method would benefit them in university exams. Overall, 89.7% of participants found the methods highly satisfactory, 50% satisfactory and 10.3% unsatisfactory.: Competency-specific formative assessments using multiple-choice questions and photos before and after lectures were found to improve anatomy knowledge. The strategy was found to promote engagement, memory and clinical understanding, reinforcing anatomical concepts. The results of this study suggested that competency-specific formative assessments added value to the current CBME-based medical education by increasing learning and practical application.

Motor competence assessment represents one of the most important topics in the field of motor development and physical education. The present cross-sectional study aims to assess basic motor competence, self-perception and enjoyment during PA in a sample of normal weight and overweight-obese children post covid-19 pandemic. The sample (N= 107, age= 8-9 years old) was recruited from an experimental project in Lecce (Apulia). Motor competence assessment was conducted with MOBAK 3-4 protocol, and self-perception and enjoyment were evaluated with two validates questionnaires. Multivariate analysis of variance (MANOVA) has been performed to assess effect of gender and BMI on considered variables. Results from MANOVA showed significant main effect for gender [F(10,93) = 2.353, p= .013, η²= 0,218] and BMI cutoff [F(10,93) = 2.351, p= .013, η²= 0,218]. However, interaction effect was no significant. Moreover, independent t-test highlighted significant differences in catching, dribbling, balancing and object movement according to gender (p< .05), and in balancing, rolling and self-movement according to BMI cutoff (p< .05). Self-efficacy differed significantly between male and female. No effect was found for enjoyment. Further studies should investigate the effect of BMI and factors related to physical activity on motor competence development.

The Next Era of Assessment Within Medical Education: Exploring Intersections of Context and Implementation.

In competency-based medical education (CBME), which is being embraced globally, the patient-learner-educator encounter occurs in a highly complex context which contributes to a wide range of assessment outcomes. Current and historical barriers to considering context in assessment include the existing post-positivist epistemological stance that values objectivity and validity evidence over the variability introduced by context. This is most evident in standardized testing. While always critical to medical education the impact of context on assessment is becoming more pronounced as many aspects of training diversify. This diversity includes an expanding interest beyond individual trainee competence to include the interdependency and collective nature of clinical competence and the growing awareness that medical education needs to be co-produced among a wider group of stakeholders. In this Eye Opener, we wish to consider: 1) How might we best account for the influence of context in the clinical competence assessment of individuals in medical education? and by doing so, 2) How could we usher in the next era of assessment that improves our ability to meet the dynamic needs of society and all its stakeholders? The purpose of this Eye Opener is thus two-fold. First, we conceptualize - from a variety of viewpoints, how we might address context in assessment of competence at the level of the individual learner. Second, we present recommendations that address how to approach implementation of a more contextualized competence assessment.

Exploring digital competencies in higher education: design and validation of instruments for the era of Industry 5.0

IntroductionIndustry 5.0 is the next phase of industrial work that integrates robots and artificial intelligence to boost productivity and economic growth. It emphasizes a balance between human creativity and technological precision, built on three pillars: human centrality, sustainability, and resilience. Corporations and educational institutions must adopt an integrated approach to training their future workforce, emphasizing digital and key competencies such as creativity, communication, collaboration, and critical thinking. Higher education institutions must measure digital competencies and other key Industry 5.0 competencies to prepare students for a sustainable future. However, there is a need to identify appropriate scientific instruments that can comprehensively evaluate these competencies.MethodsThis study conducted a Systematic Literature Review to analyze the existing digital competency assessment instruments in higher education from 2013-2023. The focus was on instruments that measure digital competencies and core competencies for Industry 5.0, such as creativity, communication, collaboration, and critical thinking. The search process began with a strategy applied across various databases, including ERIC, Google Scholar, ProQuest, Scopus, and Web of Science, to cover a broad range of literature on the design and validation of digital competency assessment tools.ResultsThis search generated a total of 9,563 academic papers. Inclusion, exclusion, and quality filters were applied to select 112 articles for detailed analysis. Among these 112 articles, 46 focused on designing and validating digital competency assessment instruments in higher education. Within the reviewed literature, surveys and questionnaires emerged as the predominant methods utilized for this purpose. This study found a direct relationship between digital competencies and essential skills like communication and critical thinking.DiscussionThe study concludes that assessment tools should integrate a wide range of competencies, and students and educators should be actively involved in developing these skills. Future research should focus on designing tools that effectively evaluate these competencies in dynamic work contexts. Assessment instruments should cover a broader range of competencies, including creativity and collaboration, to meet the demands of Industry 5.0. Reliable assessments of digital competencies and soft skills are crucial, with a need for appropriate reliability tests that do not impact students’ preparedness for labor market challenges.

Mastering the Game: How Level Structure and Game Elements Shape Competency Acquisition

Understanding the dynamics of level structure and game elements in digital educational games is paramount to fostering competency acquisition. How levels are organized within a game, along with the use of various game elements, has a significant impact on the learning outcomes and skill development of individuals. Through the strategic design and implementation of these components, educational games can effectively engage learners and facilitate the acquisition of competencies in multiple domains. In addition to structure, the integration of gamification elements can have a profound impact on learner engagement and sustainable skill acquisition. Therefore, a key element for the success of a serious game is to create appropriate personalization and a balanced relationship between learning and gaming experience. As a result, a mini-game called "Basketball Physics Challenge" has been designed to be integrated into an intelligent, adaptive physical learning game centered around force and motion as part of an ongoing research project. By playing the game "Basketball Physics Challenge", players will apply their understanding of basic physics principles in a realistic, interactive, and virtual setting. An experimental design was used to test the mini-game, in which a gamified and a non-gamified version were used and compared. 20 participants completed the experiment, and their learning progress was meticulously tracked. Using competency-based knowledge space theory, the mini-game facilitated in-game competency assessment, enabled monitoring of learning progress, tailored learning experiences, and provided individualized formative feedback. The pilot was used to develop and implement a competency model that will be the subject of future in-depth studies. The results indicated that the gamified version of the game led to slightly higher engagement and performance levels compared to the non-gamified version, although the difference in learning outcomes between the two versions was not statistically significant. The analysis also showed that an optimal number of levels and a balanced integration of game elements are crucial for maintaining engagement without causing cognitive overload. Furthermore, the order in which the game versions were presented affected player performance, with initial exposure to gamification leading to better outcomes. These findings provide valuable information for the design of educational games and their effectiveness in skill acquisition. This research supports the development of powerful educational technologies that enhance learning through a coherent level structure and meaningful use of game elements that effectively promote learner engagement.

Comparative Study of Nursing Informatics Competencies in Educators, Students, and Clinical Nurses

Background: Nursing informatics refers to a specialty in nursing that influences the learning environment, interprofessional collaboration, patient care, strategic planning, and patient satisfaction. Nursing informatics competency has been identified as a critical factor influencing the quality-of-care services. Nurses must integrate informatics into clinical decision-making processes. Objectives: This study aims to conduct a comparative analysis of nursing informatics competency among nursing educators, students, and clinical nurses. Methods: This descriptive-analytical study was conducted in 2023 at the nursing faculty of Abadan University of Medical Sciences. The study sample included 670 participants: Nursing educators, students, and clinical nurses. Nursing educators and students were selected through a census method, while clinical nurses were chosen via random sampling. Data were collected using the Nursing Informatics Competency Assessment Tool (NICAT) and demographic questionnaires. The NICAT assesses informatics competency across 30 components, categorized into three dimensions: Computer literacy, informatics literacy, and information management skills. Data were analyzed using SPSS version 26 software. Results: The average nursing informatics competency score among the participants was 105.58, falling within the competent range. Nursing educators achieved the highest competency score (110.21), followed by clinical nurses (106.24) and students (103.78). The highest score was observed in informatics literacy (45.84), while the lowest score was seen in information management skills (24.59). Information management skills, computer literacy, and informatics literacy were significantly correlated with the overall nursing informatics competency score (P < 0.001). Conclusions: Nursing educators, students, and clinical nurses were found to be competent in nursing informatics. However, due to technological advancements and the growing use of electronic health services, there is a need to enhance nurses' competencies in all dimensions, particularly in information management skills. It is recommended to revise the curriculum and provide the necessary infrastructure and equipment to integrate informatics into nursing education and empower nurses.

An Operations Chain Model for Automatic Assessment of Operation Procedure for Equipment Operators

Automatic assessment of the operation ability of operators based on computers is an essential approach for improving the effectiveness of equipment operation training and enhancing equipment safety. Present methods primarily focus on the operation results but pay less attention to the operation procedure. One reason is that there is a lack of a model that has the ability to describe all probable paths to accomplish the same task. Therefore, an operations chain model is put forward for the first time to describe the standard operation procedure and relationships among operations based on the decomposition of operational tasks and the relationships among the various operations required to fulfill the task. A specific operation task corresponds to an operations chain, which will form one or multiple standard operation sequences that will allow trainees to complete the same task through different paths. The Needleman–Wunsch sequence alignment algorithm is introduced to match the trainees’ operation sequence with all standard sequences. The maximum alignment result is the score of the trainees’ operations. An example shows that the operations chain model can accurately describe the complex structure of the standard operating procedures. The Needleman–Wunsch sequence alignment algorithm can objectively evaluate the trainee’s operation capabilities. The combination of the operations chain model and sequence alignment algorithm can form a complete operation procedure assessment method that is friendlier to trainees and has more objective evaluation results. The method will help to improve the effectiveness of the competency assessment of equipment operators.

Assessing Chest Tube Insertion Skills Using a Porcine Rib Model-A Validity Study.

Assessments require sufficient validity evidence before their use. The Assessment for Competence in Chest Tube Insertion (ACTION) tool evaluates proficiency in chest tube insertion (CTI), combining a rating scale and an error checklist. The aim of this study was to collect validity evidence for the ACTION tool on a porcine rib model according to the Messick framework. A rib model, consisting of a porcine hemithorax that was placed in a wooden frame, was used as simulator. Participants were recruited from the departments of surgery, pulmonology, and emergency medicine. After familiarization with the rib model and the equipment, standardized instructions and clinical context were provided. They performed 2 CTIs while being scored with the ACTION tool. All performances were assessed live by 1 rater and by 3 blinded raters using video recordings. Generalizability-analysis was performed and mean scores and errors of both groups on the first performance were compared. A pass/fail score was established using the contrasting groups' method. Nine novice and 8 experienced participants completed the study. Generalizability coefficients where high for the rating scale (0.92) and the error checklist (0.87). In the first CTI, novices scored lower than the experienced group (38.1/68 vs. 47.1/68, P = 0.042), but no difference was observed on the error checklist. A pass/fail score of 44/68 was established. A solid validity argument for the ACTION tool's rating scale on a porcine rib model is presented, allowing formative and summative assessment of procedural skills during training before patient contact.

Graduating Vascular Surgery Trainee Proficiency in Endovascular and Open Peripheral Revascularization Procedures

Endovascular interventions for peripheral artery disease have increased in prevalence over time given the inherent benefits of minimally invasive approaches. While it is essential that vascular surgery graduates are facile with endovascular techniques, the results of the BEST-CLI trial highlight the equivalent importance of ensuring trainee competence in open skills. Recent studies demonstrate increasing case volume of both endovascular and open procedures during vascular surgery training. Case volume is merely a surrogate marker for competence, however, and the objective competence attained by trainees at the time of graduation is unknown. We sought to investigate operative autonomy and competence of graduating vascular surgery trainees performing endovascular as compared to open peripheral vascular revascularization procedures. Operative performance and autonomy ratings for infrainguinal endovascular and open revascularizations from the Society for Improving Professional Learning Operative (SIMPL OR) application database were collected for all vascular surgery participating institutions from 2018-23. The distribution for autonomy and performance ratings were determined by training level for endovascular and open procedures, respectively. Mixed effects logistic regressions were conducted to estimate the predictive association between procedure type and autonomy and performance assessment, adjusting for training level and case complexity. Subsequently, the estimated model was applied to predict the probability of a graduating trainee being rated as meaningfully autonomous or competent while performing endovascular and open procedures across various case complexities. Sixty-nine residents from 23 programs (12 fellowship, 11 residency) were assessed on 706 revascularization procedures (n=383 endovascular, 323 open). When controlling for training level and case complexity, there were no differences in autonomy (OR 1.11 [95% CI: 0.62-1.99]) or competency assessment (OR 0.86 [95% CI: 0.46-1.59]) for endovascular, as compared to open, peripheral revascularization procedures. For average complexity procedures, the predicted probability of a trainee being assessed as competent and autonomous at the time of graduation was high (competent: 88% endovascular, 86% open; autonomous: 96% endovascular, 97% open). Predicted probability of competence and autonomy for complex procedures was lower but remained similar between groups (competent:73% endovascular, 70% open; autonomous: 92% endovascular, 92% open). There is no difference in the graduating level of autonomy and competence of endovascular as compared to open peripheral revascularization procedures for vascular surgery trainees. These findings suggest vascular surgery trainees enter independent practice with adequate proficiency to utilize the full scope of techniques to care for patients requiring peripheral revascularization procedures.

Establishing Triage Competencies and Verification Processes: A Survey Study

IntroductionAlthough the ED triage function is a critical means of ensuring patient safety, core competencies for ED triage are not well defined in the literature. The purpose of the study was to identify and validate emergency triage nursing competencies and to develop a competency verification process. MethodsA sample of 1181 emergency nurses evenly divided between roles with oversight of triage training and competency assessment (manager-level and staff nurses performing triage) completed an online survey evaluating competency elements that comprised the following in terms of frequency and importance, training modalities, and evaluation methods: expert assessment, clinical judgment, management of medical resources, communication, and timely decisions. ResultsBoth manager-level and triage nurses agreed on the importance of the identified competencies. Gaps in training and evaluation were reported by both staff nurses and manager-level nurses. Triage nurses reported less training offered and less competency evaluation compared with manager-level nurses. Triage nurses reported performing all competencies more frequently and at higher level of competency than manager-level nurses reporting on triage nurse performance. DiscussionThis study provides both a standard set of triage competencies and a method by which to evaluate them. Managers and educators might consider this standard to establish initial triage role competency and periodic competency assessment per institutional guidelines. The gap in perceived education and evaluation suggests that standard education and evaluation processes be adopted across emergency departments.

Teaching posterior composite restorations: A survey of dental schools in Palestine

AimThis study aimed to assess different aspects of teaching posterior composite restorations in two dental schools in Palestine. Materials and methodsA questionnaire was emailed to the heads of the operative and conservative dentistry departments to collect detailed information on the teaching practices related to posterior composite restorations. The questionnaire comprised 22 questions structured to collect information on the time dedicated to teaching the topic, competency assessments, future plans for allocating time for each restoration type, relevant indications and contraindications, specific materials and techniques utilized in the application, and fees charged for posterior restorations. The gathered responses were collated in Excel and analyzed. ResultsBoth dental schools allocated similar teaching times to posterior composites and amalgam in their preclinical operative dentistry courses. However, there was a greater emphasis on composites in the clinical course than in the preclinical course at both institutions. Despite these differences, both institutions expressed a shared intention to allocate more time to teaching posterior composites while reducing the emphasis on teaching amalgam procedures. Consistency was observed across competency testing, cavity design preferences, and contraindications, with both schools favoring slot-type cavities. Furthermore, uniformity was noted in the management of operatively exposed dentin and matrix techniques, although variations existed in moisture isolation. Notably, both schools taught circumferential and sectional metal matrices but did not teach clear sectional matrices or use of bulk-fill composites. Additionally, the adhesive and light-curing practices remained consistent across both institutions. ConclusionThe findings of this study indicate that the teaching of posterior composite restorations is consistent across both Palestinian dental schools. Their curricula are aligned with contemporary international practices, demonstrating a strong commitment to modern operative dentistry and adherence to global standards. These findings offer valuable insights for educators and researchers and emphasize the need for ongoing adaptations to maintain high clinical standards.

METHODS AND TOOLS FOR ASSESSING STUDENT COMPETENCIES

The article deals with the detailed information about Methods and tools for assessing student competencies. The accurate assessment of student competencies is crucial in modern education, as it allows educators to measure not only knowledge retention but also skills, attitudes, and critical thinking abilities. This paper explores various methods and tools used for assessing student competencies, including traditional assessments, performance-based assessments, and technology-enhanced assessments. Traditional methods, such as multiple-choice tests and written exams, remain popular but are often limited in their ability to evaluate higher-order thinking skills. In contrast, performance-based assessments—such as projects, presentations, and portfolios—offer a more comprehensive evaluation by focusing on the application of knowledge in real-world contexts. Technology-enhanced tools, such as digital simulations, e-portfolios, and automated feedback systems, provide innovative ways to measure competencies while increasing engagement and personalization. The paper also discusses the importance of aligning assessment tools with learning objectives and provides insights into the challenges associated with each method, including issues of reliability, validity, and scalability. By combining multiple assessment methods, educators can obtain a holistic view of student competencies, enabling targeted support and improved learning outcomes.

TRANSITIONING FROM AN INSTITUTIONALLY DEFINED CANDIDATE SEARCH TO THE ANALYTIC HIERARCHY PROCESS: IMPROVING FACULTY SELECTION

This article presents a comprehensive model using the Analytic Hierarchy Process (AHP) for faculty search and selection at a regional university. After developing and applying evaluation criteria based on generalized position descriptions, the search committee chose to revise the criteria using the AHP. The revision allowed for more detailed and relevant assessments of candidate competencies and experience. While full implementation of the AHP was time-constrained, outcomes revealed greater consensus regarding preferred qualifications and presented a clearly defined rationale to support recommendations. In the decision-making process, the main criteria included degree, teaching, student engagement, research, service, experience, and diversity. Some of the main criteria had associated detailed sub-criteria. Although the AHP is typically used early in the faculty selection process, in this specific scenario, the initial elimination of candidates from the pool was made simpler by clearly defining the required qualifications and then closely evaluating the preferred qualifications. This article aims to assist higher education institutions in prioritizing and ranking their selection criteria, which have been found to be similar across different institutions.
