In order to improve vitality and efficiency of teaching in music, with the multi-sensing, immersion and interactivity feature in the virtual reality (VR) technology, the VR system can solve the low cross mutual inductance and low efficiency in traditional music teaching. An online error identification algorithm was proposed in the paper. The teaching performance was evaluated with dimensions and confirmatory factor analysis. The results indicate the enthusiasm of students' autonomous learning and learning efficiency has been greatly improved with teaching system.

This research aims to examine the components and inhibiting factors of the teacher’s work performance in the teaching assignments of Buddhist education teachers. The authors believe that the theoretical as well as the practical problems of Buddhist education teachers can be solved by examining its components and the inhibiting factors. This research was developmental research that begins by compiling the component of performance instrument and the inhibiting factors instrument through Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA). The data were then analyzed through regression analysis. The subjects of research were Buddhist education teachers in Central Java, Indonesia. The results of the research show the values of Anti-image > 0.5 for 7 indicators. Meanwhile, the loading factor was bigger than 0.5 for each component. The model had RMSEA ≤ 0.05, Chi-Square (X²) > 0.05, P = 0.55, the GFI was 0.97, which means the model was fit. The teaching performance components of Buddhist education teacher include planning the learning program, implementing the learning program, and evaluating the learning program. The inhibiting factors of the teacher’s performance are the additional tasks, the classroom atmosphere, conflict, and work pressure. This research has proved that the inhibiting factors have a negative impact on the teaching performance of Buddhist education teachers.

Swimming is one of the most popular spots among college students, though it is hard to master. With virtual reality (VR) technology, problems of the low-cross mutual inductance and low efficiency can be solved. A physical model and the software framework of the virtual reality system was proposed. The swimming teaching system can solve the problem that perception-action separation, improve the study ecological validity, and hold great promise for the study of perception- action. A comparison analysis between students' correct and wrong swimming movements is carried out, and the analysis results show that the virtual reality system solves the problem of monotonicity in real swimming teaching.

The present study aims (a) to translate and adapt the Igroup Presence Questionnaire (IPQ) to the Portuguese context (semantic equivalence/ conceptual and content validity) and (b) to examine its psychometric properties (reliability and factorial validity). The sample consisted of 478 subjects (285 males and 193 females). The fidelity of the factors varied between 0.53 and 0.83. The confirmatory factor analysis results produced a 14-item version of IPQ-PT, accepting covariance between residual errors of some items of the instrument, as the best structural representation of the data analyzed. The CFA was conducted based on a three-variable model. The fit indexes obtained were X2/df = 2.647, GFI = .948, CFI = .941, RSMEA = .059, and AIC = 254. These values demonstrate that the proposed Portuguese translation of the IPQ maintains its original validity, demonstrating it to be a robust questionnaire to measure the sense of presence in virtual reality studies. It is therefore recommended for use in presence research when using Portuguese samples.

The Relationship

As virtual reality becomes more prevalent in society, there has been a renewed focus on developing experiences for consumers to enjoy (Hartl and Berger, 2017). The current research project explores the relationship between presence, game attractiveness, suspense, and enjoyment in watching mediated sports content and exploring the differences between these constructs in 2D presentation versus 360 video presentation. Participants were asked to provide demographic information, watch a video presented either on a traditional monitor screen or in 360-degree video on the Oculus Rift and then complete surveys to assess their experience watching the clip. This data will be analyzed via confirmatory factor analysis to determine if presence, game attractiveness, suspense, and enjoyment are linked. Furthermore, 2D and 360 video conditions were also compared through MANOVA to determine if there are differences between conditions in regard to presence, suspense, and enjoyment.

This article investigates the psychometric properties of the Revised Child Anxiety and Depression Scale (RCADS). A group of 704 adolescents completed the questionnaires in their classrooms. This study examines potential confirmatory factor analysis factor models of the RCADS as well as the relationships between the RCADS and the Screen for Child Anxiety Related Emotional Disorders-Revised (SCARED-R). A subsample of 595 adolescents also completed an anxiety questionnaire (Fear Survey Schedule for Children-Revised, FSSC-R) and a depression questionnaire (Center for Epidemiological Studies Depression Scale, CES-D). Confirmatory factor analysis of the RCADS suggests that the 6-factor model reasonably fits the data. All subscales were positively intercorrelated, with rs varying between .48 (generalized anxiety disorder-major depression disorder) and .65 (generalized anxiety disorder-social phobia/obsessive-compulsive disorder). The RCADS total score and all the RCADS scales were found to have good internal consistency (> .70). The correlations between the RCADS subscales and their SCARED-R counterparts are generally substantial. Convergent validity was found with the FSSC-R and the CES-D. The study included normal adolescents aged 10 to 19. Therefore, the findings cannot be extended to children under 10, nor to a clinical population. Altogether, the French version of the RCADS showed reasonable psychometric properties.

Abstract. Physical exercise when done excessively may have negative consequences on physical and psychological wellbeing. There exist many scales to measure this phenomenon. The purpose of this article is to create a scale measuring the problematic practice of physical exercise (PPPE Scale) by combining two assessment tools already existing in the field of exercise dependency but anchored in different approaches (EDS-R and EDQ). This research consists of three studies carried out on three independent sample populations. The first study (N = 341) tested the construct validity (exploratory factor analysis); the second study (N = 195) tested the structural validity (confirmatory factor analysis) and the third study (N = 104) tested the convergent validity (correlations) of the preliminary version of the PPPE scale. Exploratory factor analysis identified six distinct dimensions associated with exercise dependency. Furthermore, confirmatory factor analysis validated a second order model consisting of 25 items with six dimensions and four sub-dimensions. The convergent validity of this scale with other constructs (GLTEQ, EAT26, and The Big Five Inventory [BFI]) is satisfactory. The preliminary version of the PPPE must be administered to a large population to refine its psychometric properties and develop scoring norms.

Development And Validation

Abstract. The current paper presents the development and validation of a unit-level Organizational Citizenship Behavior (OCB) scale based on the Referent-Shift Consensus Model (RSCM). In Study 1, with 124 individuals measured twice, both an Exploratory Factor Analysis (EFA) and a Confirmatory Factor Analysis (CFA) established and confirmed a five-factor solution (helping behavior, sportsmanship, loyalty, civic virtue, and conscientiousness). Test–retest reliabilities at a 2-month interval were high (between .59 and .79 for the subscales, .83 for the total scale). In Study 2, unit-level OCB was analyzed in a sample of 129 work teams. Both Interrater Reliability (IRR) measures and Interrater Agreement (IRA) values provided support for RSCM requirements. Finally, unit-level OCB was associated with group task interdependence and was more predictable (by job satisfaction and integrity of the supervisor) than individual-level OCB in previous research.
