Pengembangan Video Tutorial Pembelajaran Basketball Dribbling

Physical and health education is carried out as part of an organized and continuous education process to acquire knowledge, personality, skills, health, and physical fitness. In this education, three domains must be achieved, such as cognitive, affective, and psychomotor. Of the three domains, the dominant one is the psychomotor domain because many subjects are directly related to motion values, such as movement abilities and skills. One of the compulsory subjects in the sports coaching study program, the Health Sports Education Study Program, Universitas Jambi, is basketball. Science and technology (IPTEK) is a term we often hear in everyday life. The development of society in all areas of life is inseparable from the existence of science and technology. In general, there is an assumption that the mastery and application of science and technology will guarantee the progress of society. This research is research and development. Research and development is a research method used to produce particular products and test the effectiveness of these products. In this case, research and development were carried out to obtain a video tutorial for learning basketball dribbling in the Health Sports Education Study Program, Universitas Jambi. This research and development were carried out based on the study that video tutorials for teaching basketball dribbling in the Health Sports Education Study Program at Universitas Jambi were not available. The research results showed that a video tutorial on basketball dribbling was arranged for the Health Sports Education Study Program, at Universitas Jambi. With the feasibility level based on the assessment of material experts, a percentage of 90% is included in the very feasible category, and the media expert's assessment is obtained with a percentage of 90%, including the very feasible category. The trial results obtained a percentage of 72% including the feasible category.

Rasch validation of the Warwick-Edinburgh Mental Well-Being Scale (WEMWBS) in community-dwelling adults

BackgroundWith the ongoing global COVID-19 pandemic and the recent political divide in the United States (US), there is an urgent need to address the soaring mental well-being problems and promote positive well-being. The Warwick-Edinburgh Mental Well-Being Scale (WEMWBS) measures the positive aspects of mental health. Previous studies confirmed its construct validity, reliability, and unidimensionality with confirmatory factor analysis. Six studies have performed a Rasch analysis on the WEMWBS, and only one evaluated young adults in the US. The goal of our study is to use Rasch analysis to validate the WEMBS in a wider age group of community-dwelling adults in the US.MethodsWe used the Rasch unidimensional measurement model 2030 software to evaluate item and person fit, targeting, person separation reliability (PSR), and differential item functioning (DIF) for sample sizes of at least 200 persons in each subgroup.ResultsAfter deleting two items, the WEMBS analyzed in our 553 community-dwelling adults (average age 51.22 ± 17.18 years; 358 women) showed an excellent PSR = 0.91 as well as person and item fit, but the items are too easy for this population (person mean location = 2.17 ± 2.00). There was no DIF for sex, mental health, or practicing breathing exercises.ConclusionsThe WEMWBS had good item and person fit but the targeting is off when used in community-dwelling adults in the US. Adding more difficult items might improve the targeting and capture a broader range of positive mental well-being.

Physical body experiences questionnaire simplified for active aging (PBE-QAG): Rasch validation.

To validate the Physical Body Experiences Questionnaire simplified for Active aGing (PBE-QAG) with Rasch Measurement Theory. PBE-QAG measures body awareness during physical activity. Community-dwelling adults were recruited at the Minnesota State Fair, Highland Fest, and in the Brain Body Mind Lab (University of Minnesota). They completed demographic, clinical, and behavioral questionnaires and the PBE-QAG, which has 12 items, with scoring options ranging between 0 (totally true) and 4 (totally false). A lower total PBE-QAG score on reflects better body awareness. We validated the structural validity of PBE-QAG in community-dwelling older adults, and in community-dwelling adults (18-99 years of age). We also performed a pilot structural validity in community-dwelling adults with chronic stroke. We evaluated item and person fit, targeting, unidimensionality, person separation reliability, differential item functioning for demographic and clinical characteristics, principal component of residuals, and local item dependence. We obtained unidimensionality and item fit after deleting and rescoring items in older adults (n = 133), adults (n = 530), and adults with chronic stroke (n = 36). In community-dwelling adults, 7 participants did not fit the model (1.13%). There was minimal floor (5.28%), no ceiling effect (0.00%), and no local item dependence or differential item functioning. The person mean location was -1.77±1.22 logits. PBE-QAG demonstrated good item and person fit, but the targeting is off. Therefore, the current version of PBE-QAG is not recommended for use in community-dwelling adults. We encourage further validation of PBE-QAG by adding more difficult items. We also recommend evaluating the PBE-QAG in a larger group of adults with stroke.

Teacher self-efficacy and reasons for choosing initial teacher education programmes in Norway and New Zealand

In samples of teacher education students in New Zealand and Norway, we explored their reasons for choosing teaching and their sense of self-efficacy for teaching. We examined the factor structure of the newly developed Reasons for Choosing Teacher Education Scale (RCTES) and the established Norwegian Teacher Self-Efficacy Scale (NTSES). The factor structure of the NTSES and the RCTES were consistent with expectations and previous research. We found that altruism, personal fit with teaching, and job security were the strongest reasons for going into teaching in both samples, and that teacher self-efficacy is related to motives for entering initial teacher education.

Measuring palliative care self-efficacy of intellectual and developmental disability staff using Rasch models.

The objectives of this study were to evaluate the psychometric properties of a palliative care self-efficacy instrument developed for intellectual and developmental disability (IDD) staff using Rasch analysis and assess the change in palliative care self-efficacy between 2 time points using Rasch analysis of stacked data. Staff from 4 nonprofit IDD services organizations in a US Midwestern state (n=98) answered 11 questions with Likert-style responses at baseline and 1-month follow-up post training. Rasch analysis was performed to examine rating scale structure, unidimensionality, local independence, overall model fit, person and item reliability and separation, targeting, individual item and personal fit, differential item functioning (DIF), and change in palliative care self-efficacy between 2 time points. The rating scale structure improved when 5 response categories were collapsed to 3. With the revised 3 response categories, the instrument demonstrated good psychometric properties. Principal components analysis of Rasch residuals supported the assumption of unidimensionality. Model fit statistics indicated an excellent fit of the data to the Rasch model. The instrument demonstrated good person and item reliability and separation. Gender-related DIF was found in 1 item, and work tenure-related DIF in 3 items. Overall palliative care self-efficacy improved between 2 time points. Rasch analysis allowed for a more thorough examination of this palliative care self-efficacy instrument than classical test theory and provided information on rating scale structure, targeting, DIF, and individual persons and items. These recommendations can improve this instrument for research and practical contexts.

Predicting injury risk using machine learning in male youth soccer players

The aim of this study was twofold: a) to build models using machine learning techniques on data from an extensive screening battery to prospectively predict lower extremity soft tissue (LE-ST) injuries in non-elite male youth soccer players, and b) to compare models' performance scores (i.e., predictive accuracy) to select the best fit. A sample of 260 male youth soccer players from the academies of five different Spanish non-professional clubs completed the follow-up. Players were engaged in a pre-season assessment that covered several personal characteristics (e.g., anthropometric measures), psychological constructs (e.g., trait-anxiety), and physical fitness and neuromuscular measures (e.g., range of motion [ROM], landing kinematics). Afterwards, all LE-ST injuries were monitored over one competitive season. The predictive ability (i.e., area under the receiver operating characteristic curve [AUC] and F-score) of several screening models was analysed and compared to select the one with the highest scores. A total of 45 LE-ST injuries were recorded over the season. The best fit screening model developed (AUC = 0.700, F-score = 0.380) allowed to successfully identify one in two (True Positive rate = 53.7 %) and three in four (True Negative rate = 73.9 %) players at high or low risk of suffering a LE-ST injury throughout the in-season phase, respectively, using a subset of six field-based measures (knee medial displacement in the drop jump, asymmetry in the peak vertical ground reaction force during landing, body mass index, asymmetry in the frontal plane projection angle assessed through the tuck jump, asymmetry in the passive hip internal rotation ROM, and ankle dorsiflexion with the knee extended ROM). Given that these measures require little equipment to be recorded and can be employed quickly (approximately 5–10 min) and easily by trained staff in a single player, the model developed might be included in the injury management strategy for youth soccer.

The productivity tax of new office concepts: a comparative review of open-plan offices, activity-based working, and single-office concepts

This systematic review critically analyzes the relationship between office concepts and individual and organizational performance. Based on the current literature, we identify seven key dimensions to guide our understanding: office concept, work, personality fit, satisfaction, health, control paradigm, and enabling paradigm. Our systematic search yielded 429 published papers on office concepts and performance between 2005 and 2022. Rigorous selection criteria narrowed them down to 46 empirical articles included in this analysis. The results show that activity-based working not only negatively impacts performance but also affects employee satisfaction and health. Open-plan offices can reduce real-estate costs but lead to lower performance levels, thereby imposing a tax on productivity which outweighs the initial cost savings. Activity-based working has the potential to enhance collaboration and interaction but is dependent on a professional and proactive management. In most cases, especially for knowledge workers, the single office turns out to be the environment in which employees show the best individual and organizational performance.

Emphasizing effort vs talent in personal trainers' performance: consumption response of personal fitness training customers

PurposeFitness service companies often promote the companies' personal training service by attributing trainers' competent characteristics, qualifications or/and service provision to their effort or talent. This promotion is called performance attribution promotion. Utilizing attribution theory and the theory's adjacent studies, this study investigated whether and why performance attribution promotion affects consumers' service purchase of personal fitness training.Design/methodology/approachThe authors developed the experimental stimuli of performance attribution promotion and validated those through a pretest (N = 200). Using the validated stimuli, the authors conducted an experiment with employing a single factor between-subject design (performance attribution promotion: effort vs talent) based on random assignment (N = 200).FindingsThe analysis results revealed that attributing trainers' competent characteristics, qualifications or/and service provision to effort (vs talent) leads to a higher level of service registration intention. Moreover, this effect was mediated by the perceived teaching expertise but not by the perceived teaching trustworthiness.Originality/valueThese findings enrich the literature by illuminating a new mechanism and consequence of performance attribution promotion. The authors' study also extends the marketing studies related to expertise perception by presenting the attribution of visible features as one of the characteristics determining expertise perception. Finally, the authors' findings also have implications for fitness service companies and other stakeholders that seek to effectively leverage trainers' competent outcomes for consumer acquisition.

KEY PERFORMANCE INDICATORS (KPI) AND WAYS OF THEIR APPLICATION IN THE FITNESS INDUSTRY OF UKRAINE

Introduction. The article examines modern approaches to assessing the performance of fitness club employees based on the use of key performance indicators (KPI) and analyzes operational and strategic KPI. The advantages and disadvantages of using key performance indicators (KPI) to evaluate the work of fitness club staff are determined. The purpose of the work is to determine the key performance indicators (KPI) of the fitness club staff and ways of their application in the fitness industry of Ukraine. Materials and methods: analysis; synthesis; comparison. Results. In the course of the study, the peculiarities of the application of key performance indicators (KPI) in fitness clubs of Ukraine are determined. The priority of the indicators should be determined taking into account their importance and necessity, that is, determine those indicators, the implementation of which contributes to the achievement of the goal. Examples of KPI that can ensure the effectiveness of the personal fitness trainer and the company's sales department are given. The implementation and effective use of key indicators will allow fitness clubs not only to achieve the set goal, but also to identify a number of problems that "inhibit" its achievement. It is shown that in order to create an effective system of key indicators of a fitness club, both professional skills (knowledge of the subject area, work experience, qualifications) and competent intuition and a creative approach are necessary. The advantages of using KPI for employees of fitness clubs are understanding the purpose of their work, awareness of personal benefit in case of success; analysis of the activities of subordinates, identification of problem areas, assessment of the quality of work of staff and managers; timely adjustment of plans and goals of the fitness club; feedback between employees and management. In this case, the main shortcomings are the incorrect interpretation of key performance indicators; excessive number of criteria; the need for global staff retraining, staff turnover. Conclusion. The future development and application of KPI in fitness clubs largely depends on the market conditions of the Ukrainian fitness market and the desire to integrate into the international market, as well as on the speed of management development and the effectiveness of management analysis in domestic fitness clubs.

Personal fitness training services to improve health outcomes: A survey exploring clients' perspectives

It is currently unclear how personal fitness training (PT) clients in Serbia evaluate this service and what motivates them to be consistent with the training practice in the quest for obtaining physical literacy and health outcomes. A cross-sectional explorative study was used to investigate consumers' perceptions on the PT service with the aim to inform trainers on clients' motivational factors, challenges and experiences in the pursuit of training goals. A total of 148 respondents completed the anonymous questionnaire via Qualtrics platform. The key findings of the study can be summarised as follows: 1) PT clients in Serbia are using up these services primarily for sustained exercise adherence and motivation to attain and maintain health-related goals, 2) PT clients in Serbia highly value professional dedication of a personal trainer as well as their ability to facilitate supportive social environment, 3) Personal trainers in Serbia are expected to play a significant role in motivating clients, especially those with weight management needs and limited capacity for self-directed lifestyle changes. Additionally, there is a need for increased transparency from fitness centres regarding the qualifications of employed trainers and their backgrounds. Stakeholders should find a way to encourage PT consumers to provide feedback and express their impressions more effectively, thereby reducing the chances of losing the motivation to hire or keep a personal trainer. In conclusion, PT clients in Serbia value holistic training practices and expect their personal trainers to lead them and motivate them to reach the targeted health-related objectives.

The effect of scoring correction and model fit on the estimation of ability parameter and person fit on polytomous item response theory

Scoring quality has been recognized as one of the important aspects that should be of concern to both test developers and users. This study aimed to investigate the effect of scoring correction and model fit on the estimation of ability parameters and person fit in the polytomous item response theory. The result of 165 students in the Statistics course (SATS4410) test at one of the universities in Indonesia was used to answer the problems in this study. The polytomous data obtained from scoring the test results were analyzed using the Item Response Theory (IRT) approach with the Partial Credit Model (PCM), Graded Response Model (GRM), and Generalized Partial Credit Model (GPCM). The effect of scoring correction and model fit on the estimation of ability and person fit was tested using multivariate analysis. Among the three models used, GRM showed the best fit based on p-value and RSMEA. The results of the analysis also showed that there was no significant effect of scoring correction and model fit on the estimation of the test taker’s ability and person fit. From the results of this study, we recommend the importance of evaluating the levels or categories used in scoring student work on a test.

Rasch and Confirmatory Factor Analyses of the Arabic Version of the Diabetes Self-Management Scale (DSMS): An Intercultural Approach.

The current study was designed to validate the Arabic version of the Diabetes Self-Management Scale (DSMS) using Rasch and confirmatory factor analyses. This included person and item fit, separation, and reliability; rating scale functionality to evidence substantive validity; unidimensional structure to evidence structural validity; and item technical quality to evidence content validity. The study was conducted between September 2021 and March 2022. Utilizing AMOS-based confirmatory factor analysis (CFA), the study also assured the dimensionality of the DSMS. The participants were 103 diabetic patients in Saudi Arabia with a mean age of 44.72 years (standard deviation = 17.35). The analysis was performed using a trichotomous rating scale, and only one item exhibited a misfit (DSMS14). The item difficulty range was -1.0 to +1.0 logits, while the person's ability range was -3.0 to +3.0 logits. The first construct proved one Rasch dimension, which was explained and further analyzed using AMOS-CFA for the one-factor model. The DSMS was shown to be beneficial as a screening instrument for patient-reported diabetes self-management, despite several flaws that need to be addressed to improve the scale further.
