...

Participation is recognised as an important indicator of school inclusion and educational success of children with and without disabilities and one of the fundamental human rights. In particular, the participation in leisure activities plays a vital role in children’s life and needs to be given a higher attention. The aim of the present exploratory study was to reflect on the inclusion of children with disabilities in Portuguese schools, by portraying and comparing their participation profiles in leisure activities to those of typically developing peers. The participation patterns in leisure activities of 61 children with disabilities and 114 children without disabilities were assessed. Results indicate that the pattern of participation of children with and without disabilities differs whether they are school or community-based activities. Regarding school-based activities, findings reveal that children with disabilities participate more frequently in these activities, but in solitary and constrained spaces at school compared to children without disabilities. For community contexts, our findings indicate that children with disabilities participate in less diverse activities than children without disabilities. In addition, the range of activities is correlated to their level of independence. This exploratory study contributes to an understanding of the pattern of participation of children with and without disabilities.

The primary goal of this research is to explore absenteeism tendency, and the attitudes towards absenteeism and cheating of students who attended the teacher certificate program. In addition, this research aims to identify the views of students and lecturers on cheating and absenteeism. A sequential explanatory mixed-method research design was employed in this research. The sample of the quantitative data was 321 teacher certificate program students studying at Mugla Sitki Kocman University, Turkey. Absenteeism tendency, cheating attitude and absenteeism attitude scales were used to collect the data. Descriptive statistics, correlation, independent t-test, one-way analysis of variance (ANOVA) and Tukey HSD tests were used to analyze the data. Qualitative data was collected through semi-structured interview forms. 14 students and 14 lecturers were interviewed, recorded, and transcribed. Qualitative data was analyzed through quantitative content analyses and descriptive analyses. Research findings show that verbal field students have significantly more positive cheating attitudes than quantitative field students. While cheating attitudes show no significant difference between genders, students in physical education departments have higher scores in the dimensions of environmental conditions and opportunity and ability than verbal and quantitative field students. Both students and lecturers describe cheating as “unfair behavior and plagiarism,” and absenteeism as a “right” in unavoidable situations. It is emphasized that the active participation of students in classes mostly depends on the instructor.

This study aims to analyze whether academics’ organizational cynicism attitudes and levels of organizational identification in the field of sports sciences differ based on certain variables and determine if any relationship exists between these two variables. “Organizational Cynicism Scale” and “Academics’ Organizational Cynicism Scale” were applied to 106 academics as a data collection tool. Mann-Whitney U test and Kruskal Wallis test were used for nonparametric statistical data analysis. Bonferroni correction was taken into account in order to identify different groups. Spearman order correlation coefficient was calculated in order to identify the correlations among variables. The findings suggest that academics’ organizational cynicism and identification sub-dimensions did not display significant differences in terms of gender, marital status and academic title. However, significant differences were found among some sub-dimensions in terms of sufficiency of institution’s physical facilities, the status of place where the institution is located and financial aid from the institution. Additionally, negative and moderately significant correlations were found between all sub-dimensions of organization cynicism attitude and cognitive/behavioral/affective organizational identification sub-dimensions. It is considered that the present study will make important contributions to educational psychology thanks to its findings.

The purpose of this research is to examine the correlation between the attitude towards reading and the perception of creative reading. The sample group of the study, in which the correlational survey model among the qualitative research designs was conducted, consists of 319 students studying at fourth grade in primary schools. The scale for the perception of creative reading generated by Yurdakal and Susar Kirmizi and the scale for the attitude towards reading formed by Yurdakal and Susar Kirmizi were applied in collecting data for the research. Pearson Product-Moment Correlation Analysis and Simple and Multiple Linear Regression Analysis were implemented for the analysis of data in the study. When the data obtained from the analyses were examined, it was observed that there was a positive and high correlation between the attitude scale towards reading and its sub-dimensions. Likewise, a positive and high correlation was determined between the perception of creative reading scale and its sub-dimensions. As the attitude towards reading increases, the perception of creative reading decreases. This finding is similar for all the sub-dimensions in the scales. It was also comprehended that the attitude towards reading was a predictor of the perception of creative reading and that there were significant correlations between the perception of creative reading and the sub-dimensions of contributions, meaning, activities, and process of reading. Along with these variables, the attitude towards reading explains the perception of creative reading at a total level of 13%.

The analyses described in this paper permitted an evaluation of whether capacity-building professional development practices were related to early childhood intervention practitioners’ reported use of capacity-building family-centered practices. This was ascertained by structural equation modeling for two different types of family-centered practices (participatory and relational) where the two models were compared to determine the better fitting model and the sizes of effects for the relationships among the variables in the models. Results provided converging evidence that capacity-building professional development engenders practitioners’ use of capacity-building family-centered practices. Implications for practice are described.

A modern teaching method influences both direct and indirect learning achievement through the student's nonacademic factors. The researcher has an intention to examine the influences of new teaching methodology on mathematics achievement towards mathematics attitude, achievement motivation, and self-efficacy of students as mediating variables (n teacher = 117, n student = 2,205). The Multilevel Structural Equation Modeling revealed that attitude towards mathematics is the most important factor in explaining the academic achievement of individual students. It could be explained the variance with achievement motivation and perceived self-efficacy of students by 60.50%. As for the modern teaching method, there was a positive effect on achievement both directly and indirectly through all three factors with statistical significance and explained conjointly about the variance of student achievement in each classroom by 99.00%. This finding suggests the importance and direction of teaching design that covers the development of relevant factors as proposed in discussions and implementations.

This study considers the interaction between an e-learning system, the Blackboard system, and the students who use it in Saudi Arabia. While previous work exists, there is limited consideration of the assessment of the preferences of e-learning system usability variables based on students’ perspectives, especially in developing countries such as Saudi Arabia. This paper attempts to fill the gap by investigating the relative importance of the design criteria developed for e-learning system usability evaluation from the students’ perspective in Saudi tertiary education. Based on reviewed literature, a set of usability principles was developed that have had an influence in the students’ learning process and use of the e-learning system. The list includes system navigation, system learnability, visual design, information quality, instructional assessment and system interactivity. An exploratory study was carried out to identify the most important usability design characteristics from a student’s perspective and then evaluate the overall usability of the current e-learning system, based on this subset. A quantitative approach was adopted to weigh usability design characteristics, based on 181 learners’ perceptions. The sample consists of undergraduates who are users of a web-based e-learning system in a university in Saudi Arabia. The research instrument was tested for construct validity and reliability. The analysed results have shown that information quality is the most important dimension followed by the navigation of the e-learning system. The study has also revealed that the system learnability and visual design came third and fourth in order of importance of e-learning system usability assessment. Finally, the least important design categories that influenced the e-learning system usability assessment were instructional assessment and system interactivity. The empirical results of this study may help to provide insights for designers and evaluators leading to a more effective approach to improve the usability and uptake of the e-learning system.

This paper presents how the process of flipped teaching with Computer Assisted Language Learning (CALL) works in teaching English as a Foreign Language (EFL) writing in the Indonesian context. As well, it also elaborates how the teaching model affects learner autonomy. This flipped teaching with CALL was experienced by some lecturers of private universities in East Java, Indonesia. This study used a multi-site case study research design. The data were yielded from in-class observation, lesson plan analysis, focus group interviews, and questionnaires. The total of 5 EFL writing teachers and 150 students from 5 private universities in East Java, Indonesia had participated in this study. Experimenting with flipped teaching with CALL in teaching EFL writing enabled the teachers, as course developers, to get an idea of their students’ response to the challenges of new ways, methods, and techniques of their study. The flip-class environment fostered better communication amongst learners and learner autonomy as well. The flip-class atmosphere also had a beneficial impact on the motivation of learners. The qualitative results from interviews of the learners showed that the learners had inspired themselves to engage in in-class learning activities and self-regulated teaching environments. The findings gave reflection to the teachers on several vitally necessary conditions enabling a course in a flipped teaching with CALL format to contribute to developing students’ professional competencies.

This study has been carried out with the families who migrated from Turkey and settled in Amsterdam, the Netherlands, which has an intense cultural and educational diversity. Finding the answer to the question “According to whom; who is who?” constitutes the fundamental ground of this research. However, this research has also been carried out in order to comprehend the points of view that have changed or have not changed between the past and the present and to scrutinize the reasons for such points of view. Moreover, another main objective is to form a comparative opinion about the situations that the settled migrant families in Amsterdam, the Netherlands, and their children have encountered regarding the “other” concept, based on cases in their experiences, with regard to the adaptation concept. Content analysis, which is a qualitative research technique, was used during the research, whereas relevant persons have been contacted by means of the snowball sampling technique. In accordance with the obtained opinions and with the results derived from sample experiences, there surely exist differences in experiences in terms of adaptation and the marginalization-othering concept between those who migrated in the past and those migrating in the present day. Those sample experiences are discussed directly and the comments have been made by considering negative and positive concepts together.

The purpose of this research was to investigate the relationship between foreign language anxiety, shyness, language learning strategies, speaking scores and academic achievement of university preparatory students learning German. In addition, it was aimed to determine how the independent variables predict the speaking scores and academic achievement. The research sample consisted of 110 students (75 female and 35 males). Three instruments used in the study were: Foreign Language Classroom Anxiety Scale; Strategy Inventory of Language Learning and Shyness Scale. The results of this study revealed that a moderate significant negative relationship (r= -.434) was present between the students' foreign language learning anxiety and academic achievement. Besides, a significant and negative relationship (r= -.290) was found between foreign language anxiety and speaking scores of students. According to the correlation analysis, no significant relationship was identified between shyness, academic achievement and speaking scores of students. According to the analysis, a significant positive relationship was found between the students' language learning strategies and their academic achievements (r= .275). Namely, these data showed that, the level of academic achievement increases as the use of strategy increases. Similarly, shyness and foreign language anxiety show a moderate positive correlation (r= .419). According to these findings, it may be stated that shyness increases as speaking anxiety rises. Besides, it was determined that students' shyness, foreign language anxiety and language learning strategies predicted 26.4 % of their academic achievement. The results indicated that independent variables were positive predictors of students’ academic achievement. Finally, suggestions were made for German teachers to reduce the effects of shyness and anxiety in the process of foreign language learning.

In recent years, cyberbullying, which can be considered as a new form of bullying, has emerged as a result of developments in the field of technology and communication. Cyberbullying has become a social problem which has affected individuals’ lives negatively. The key to success in the elimination of cyberbullying and its negative effects lies in cyberbullying sensitivity. The present study aims to analyze teachers’ cyberbullying and cyber victimization experiences and levels of cyberbullying sensitivity based on some variables which are supposed to develop awareness regarding cyberbullying. Using survey as a research model, the present study focused on 346 teachers working at schools affiliated with Ministry of National Education in Tasova District located in Amasya (Turkey). “Personal Information Form”, “The Revised Cyberbullying Inventory for University Students” and “Cyberbullying Sensitivity Scale” were used as data collection tools. SPSS package program was used for data analysis and frequency and percentage values of demographic variables. Independent T test was used for gender and marital status variables, and One-Way ANOVA test was used for age and level of education variables. The findings of the present study revealed that most of the participants used social media websites actively and spent at least 2 or 3 hours on these websites on a daily basis. Teachers usually have a Facebook and/or Instagram account, and benefit from social media for research purposes and playing games. It can be stated that teachers have a significantly high level of cyberbullying sensitivity. However, it was also indicated that even though participants worked as a teacher, they still did cyberbully and suffered from cyber victimization in the past. While a significant difference was observed only in the dimension of cyber sensitivity in terms of marital status, age and level of education, a significant difference wasn’t observed in the dimensions of cyberbullying, cyber victimization and cyber sensitivity in terms of gender.
