The Reliability and Validity Study of ‘Classroom Practices in Inclusive Preschool Education Environment with Talented and Gifted Children Scale

The aim is to develop a scale to demonstrate the instructional approaches that teachers apply in inclusive preschool classrooms, where typically developed and talented/gifted children are educated together. A total of 156 teachers working in inclusive preschools in Ankara formed the study group. The scale consists of 22 five-point, Likert-type items. Both exploratory and confirmatory factor analyses were performed. As a result of the exploratory factor analysis, a structure consisting of three factors and 18 items was obtained. The first factor termed as ‘Differentiation’ consists of seven items, while the second factor, ‘Detection and Development of Potential’ consists of eight items, and the third factor of the scale, ‘Motivation’ consists of three items. The scale accounts for 44.61% of the total variance. As a result of the confirmatory factor analysis, it determined that the scale was in good agreement with the model in general. The Cronbach alpha internal consistency coefficient of the scale is defined as .88 and the reliability of the subscales is determined between .76 and .83. In addition, the correlation coefficients of the items in each factor are higher than .30. In general, it is found that the three-factor structure of the scale is valid and reliable.

The Psychometric Properties of the Mindfulness in Teaching Scale in a Turkish Sample

In this study, by translating the Mindfulness in Teaching Scale (MTS) developed by Frank, Jennings and Greenberg [1] into Turkish, it was aimed to investigate the psychometric properties of the Turkish version of the scale among Turkish educators. The adaptation study of the scale started with the linguistic equivalence study. After revealing that the scale was equivalent to the original form linguistically, Confirmatory Factor Analysis (CFA) was applied for the construct validity. As a result of CFA, it was observed that the two-factor structure of goodness of fit was excellent (c2/sd=2.111, IFI=.93, CFI=.93, GFI=.95 and RMSEA=.054) whereas the single factor structure was at acceptable level (c2/sd=2.982, IFI=.87, CFI=.87, GFI=.93 and RMSEA=.072) based on the compliance index value calculations. The Cronbach's-alpha internal consistency coefficient was found to be .64 for the Interpersonal Mindfulness subscale, .80 for the Intrapersonal Mindfulness subscale, and .78 for the whole scale. While the corrected item total correlations ranged from .30 to .65, it was found that t-test results for the scores of the upper 27% and lower 27% groups were significant, and the scale indicated significant relationships with the Mindful Attention Awareness Scale (MAAS) (p<.05). In order to determine the test-retest reliability, correlation coefficient was found to be statistically significant in accordance with the measurements made in 3-week interval. Overall findings demonstrated that the Mindfulness in Teaching Scale is a valid and reliable measurement tool for Turkish educators.

INVESTIGATION OF STRESS MANAGEMENT STYLES OF PROFESSIONAL VOLLEYBALL PLAYERS

Depending on the stress the organism encounters, reactions of people may vary. Stress leads to positive and negative effects on the person. The person starts to act and struggle against the stress they face. The aim of this research is to reveal the ways professional volleyball players cope with the pre-match stress. The universe of the research is volleyball players in Turkey's 3rd league, and the sample of it consist of randomly selected 100 (69 female, 31 male) athletes who played in the 3rd league during the 2016-2017 season. The scale was applied to the athletes 30 minutes before the match. The research has employed a 30-item Stress Coping Strategies (Styles) Scale developed by Folkman and Lazarus (1980) and adapted to Turkish by Sahin and Durak (1995). Cronbach Alpha internal consistency coefficient was found to be 77. Independent Samples T-test and one-way analysis of variance (One Way ANOVA) for cases with more than two groups test were used in the analysis of the obtained data. Values in the self-confident approach of lower dimensions are above the average. By contrast, a statistically significant difference was not reached in the research with regard to gender and age. It can be said that the athletes were not very stressed before the match and accordingly they did not set a strategy to cope with the stress. This condition may be related to the importance of the match or the league it is played in. In other studies conducted, it is suggested to increase the number of samples and to apply the scale to the upper leagues in order to clarify the styles of coping with stress more clearly.

Digital Reading Disposition Scale: A Study of Validity and Reliability

In this study, a Digital Reading Disposition Scale was developed to determine undergraduate pre-service teacher students' dispositions towards digital reading, opposed to a preference for printed reading material. Initially, a 20-items trial version of the scale was administered to a total sample of N=301 undergraduate pre-service teacher students in order to establish validity of the scale. According to the results of the Exploratory Factor Analysis (EFA) of the data collected by means of the 20-item trial form, it was revealed that only 12 items of the scale had a one-factor loading, which explained 65.58% of the total variance. Fit index values, derived from a Confirmatory Factor Analysis (CFA), confirmed the one-factor structure of the 12-items scale as a valid model. A satisfactory Cronbach-Alpha internal consistency coefficient of 0.952, as well as satisfactory test-retest reliability coefficient (Pearson correlation coefficient of 0.92) reapplied to n=98 pre-service teacher students three weeks after the first administration of the scale, provide evidence of the high reliability and consistent measurement of the scale over time. Furthermore, as part of an item analysis, adjusted item-total correlation of each item was calculated, and t-values for upper and lower 27% groups are reported to be significant (p<.001) for the 12 items of the scale. Accordingly, satisfactory validity and reliability indices are established for the Digital Reading Disposition Scale for the study sample in this investigation disposition.

Assessing self-regulated learning: The case of vocabulary learning through information and communication technologies

ABSTRACTFocusing on Self-Regulated Learning, this study aims to contribute a gap in current research by developing a learning environment and domain-specific measure (i.e. vocabulary learning in Information and Communication based environments) that could be used for research and pedagogical purposes in language learning. The development and validation of the instrument underwent an extended test design process. The first phase was the development of an item pool which made use of relevant literature and focus group interviews with EFL learners (n = 15). The second phase was the field-testing of the measure through its administration to 77 EFL learners. The last phase involved an evaluation of the psychometric properties of the revised instrument given to a total of 250 EFL learners. The findings from Confirmatory Factor Analysis with acceptable values of goodness of fit indices (NFI = .89; CFI = .93; TLI = .92, RMSEA = 0.06 and SRMR = 0.04) supported a 23-item, five-factor scale. The Cronbach alpha internal consistency coefficient of the overall scale was calculated to be .85, leading to the conclusion that the scale proposed here is a valid and reliable measure for systematic inquiry into EFL learners’ self-regulated vocabulary learning through technology.
