Kelley’s Discrimination Index (DI) is a simple and robust, classical non-parametric short-cut to estimate the item discrimination power (IDP) in the practical educational settings. Unlike item–total correlation, DI can reach the ultimate values of +1 and ‒1, and it is stable against the outliers. Because of the computational easiness, DI is specifically suitable for the rough estimation where the sophisticated tools for item analysis such as IRT modelling are not available as is usual, for example, in the classroom testing. Unlike most of the other traditional indices for IDP, DI uses only the extreme cases of the ordered dataset in the estimation. One deficiency of DI is that it suits only for dichotomous datasets. This article generalizes DI to allow polytomous dataset and flexible cut-offs for selecting the extreme cases. A new algorithm based on the concept of the characteristic vector of the item is introduced to compute the generalized DI (GDI). A new visual method for item analysis, the cut-off curve, is introduced based on the procedure called exhaustive splitting.

The study's goal was to examine the correlation between the computer programming self-efficacy and computational thinking skills of gifted and talented students. The capacity of the computer programming self-efficacy of gifted and talented students to predict their computational thinking skills were also examined. The relational screening model has been implemented in the research. The participants of the study were composed of 106 secondary school gifted and talented students studying the Individual Ability Recognition Program (IAR) at the Science and Art Center in the city center. Typical case sampling was applied for the student identification of the participants, 46 are female and 60 are male. Gifted and talented students' computational thinking skills were assessed using the "Computational Thinking Skills Scale” and the computer programming self-efficacy was measured by using the "Computer Programming Self-Efficacy Scale". Data were analysed by Pearson correlation analysis and simple linear regression analysis in statistical software SPSS 22. Research results found that there was a positive and high correlation between the computer programming self-efficacy and computational thinking skills. The gifted and talented students' computer programming self-efficacy demonstrated 31.5% of the total variance in computational thinking skills. This finding supports the claim which is present in the literature that self-efficacy in computer programming is the affective aspect of computational thinking skills. To predict computational thinking skills, it may be recommended to build multiple models for cognitive and affective skills of gifted and talented students.

E-learning pedagogy is used in many health training institutions in Uganda, However, despite the high investment, e-learning adoption is still low. This study aimed at ascertaining the relevance of on-line quality management in improve e-learning adoption in midwifery schools in Uganda. It used an explanatory sequential mixed methods design to ascertain if on-line quality management was significant at improving e-learning adoption and the on-line quality traits which would be implemented by midwifery schools to improve e-learning adoption. Data collection was conducted in two phases, the first entailed quantitative data collection and analysis to determine if on-line quality management was significant to e-learning adoption. The second embraced a qualitative data collection and analysis to ascertain the detailed traits of on-line quality management relevant to e-learning adoption. Linear regression analysis established on-line quality management had influence on e-learning adoption (p=0.000). On-line quality management accounted for 55.5% of the variance in e-learning adoption with a strong positive statistically significant relationship, and its salient traits included; Compact Disc, Read-Only-Memory materials meets the expectation of users, collaborative improvement of on-line quality, Learning Management System meets expectations of users, providing the best on-line experience, e-learning program being described as an excellent on-line learning experience, and guidelines for improving on-line quality. Midwifery schools therefore have to focus on the six most relevant traits of on-line quality management if they are to improve e-learning adoption.

A new index of item discrimination power (IDP), dimension-corrected Somers’ D (D2) is proposed. Somers’ D is one of the superior alternatives for item–total- (Rit) and item–rest correlation (Rir) in reflecting the real IDP with items with scales 0/1 and 0/1/2, that is, up to three categories. D also reaches the extreme value +1 and ‒1 correctly while Rit and Rir cannot reach the ultimate values in the real-life testing settings. However, when the item has four categories or more, Somers’ D underestimates IDP more than Pearson correlation. A simple correction to Somers’ D in the polytomous case seems to lead to be effective in item analysis settings.  In the simulation with real-life items, D2 showed very few cases of obvious underestimation and practically no cases of obvious overestimation. With certain restrictions discussed in the article, D2 seems to be a good alternative for these classic estimators not only with dichotomous items but also with the polytomous ones. In general, the magnitudes of the estimates by D2 are higher than those by Rit, Rir, and polychoric correlation and they seem to be close of those of bi- and polyserial correlation coefficients without out-of-range values.

This paper sought to investigate the mathematics teachers’ reflection on the role of Productive Pedagogies’ framework in festering effective classroom instruction. Two research objectives were used to discuss the reflection of the four mathematic teachers. A qualitative case study was adopted as the design of the study. Classroom observations, Research Journal and Reflective Interviews were organised to collect data for the study, while the narratives approach to data analysis was used to analyse the data collected. From the study, the mathematics teachers were able to gradually adjust to the new framework through effective reflective meetings with their colleagues and with the support of the researcher. They (mathematics teachers) reflected that, the framework helps them developed confidence, positive attitude and interest to their teaching practice. It helped fostered effective collaboration and created an atmosphere of trust between the mathematics teachers and their students. The study also suggested that the pedagogy influence the mathematics teachers to provide and received feedback from their colleagues and from their students. They were also of the view that there was a gradual shift from the traditional teacher centred instruction they are more conversant with to a more student-centred pedagogy. The implication of the study suggests the need to adopt the Productive Pedagogies framework into the Nigerian mathematics classroom to improve mathematics teacher’s classroom instruction.

Within the scope of the research, which aims to determine the leisure literacy and leisure exercise levels of the university students who volunteer in sports organizations, it is aimed to analyze the relationship and the differences of certain variables with measurement tools, as well as to examine the relationship and impact between leisure literacy and leisure exercise. In this context, 207 sports organization volunteers who participated in the study participated in the data collection, as well as a demographic information form, as well as the “Leisure Literacy Scale” and “Leisure-Time Exercise Scale" was used. In this study, the internal reliability coefficient for the Leisure literacy scale was .94 and .70 for the leisure exersice questionnaire. Descriptive statistics, independent sample t test, one-way analysis of variance (ANOVA) test and Tukey (HSD-LSD) test and Pearson Correlation test and regression analysis were used for data analysis. The findings reveal that participants have high leisure literacy (81.25 ± 14.04) and men exhibit more active leisure exercise levels, certain variables change leisure literacy and leisure exercise levels. On the other hand, positive strong relationships between leisure literacy and leisure exercise were determined, and leisure literacy was found to have a positive effect on leisure exercise level. As a result of the research, it can be stated that the volunteer participants who take part in sports organizations and evaluate their leisure time actively, the literacy knowledge, background and action level for their leisure time is an important factor that makes individuals spend their leisure by exercising.

This article proposes that the reader be nourished by avant-garde elements for new educational practices in the teaching and learning of mathematics. The writing is based on an investigation that was carried out with high school students from Puerto Rico. From a qualitative paradigm with a research design in action, it was explored how students in higher grades resolve situations within their environment. Emphasis was placed on how they analyze through situations in context, and how they build knowledge through the search for a possible solution to the problem through the Project Based Learning strategy. The emphasis in treatment was for students to experience a transdisciplinary environment. Their impressions from the study were the revealing focus of how students learn when they are presented with a situation in their environment, taking roles themselves, solving them it through a project. As part of the project they used their knowledge of science and mathematics to solve the situation. Similarly, they learned mathematical concepts that are part of the Trigonometry course and that are measured in the academic achievement tests called PR Goals, previously known as Puerto Rican Academic Achievement Tests (PPAA).

This study aimed to investigate whether Thai high school students’ perceived teacher support could enhance their reading ability through self-efficacy and sense of school belonging. The theoretical foundation of this study included the theory of social-motivational processes and social cognitive theory. Structural equation modeling was used for analysis and validation. The student questionnaire from the Programme for International Student Assessment (PISA) 2018 survey questions regarding teacher support, sense of school belonging, self-efficacy, and reading ability. The sample consisted of the data collected from the Thai students in the PISA2018 survey, with an effective sample size totaling 7968. The research results of the overall model showed that the perceived teacher support of Thai high school students’ had no direct effect on their reading ability, but their perceived teacher support had an indirect effect on reading ability through their self-efficacy and sense of school belonging. From the results can be seen that high school teachers in Thailand, in supporting and encouraging their students in learning, must simultaneously develop their perceived self-efficacy and sense of school belonging. Only thus can there be obvious help to their students’ reading ability.

Humans have had to immigrate from one country to another throughout the history because of economic problems, warfare, safety, etc. Warfare and migration definitely bring about traumatic incidents for all humanity. However, they are much more destructive for children. The current study aims to review the warfare-and-migration-themed drawings of the Syrian and Palestinian children living in Turkey as refugees in comparison to the Turkish children’s drawings. A case study design was employed as a qualitative methodology. 19 Syrian, 6 Palestinian and 25 Turkish children aged between 6-10 years studying in various primary schools in City of Istanbul made up the study sample. Children were asked to draw pictures of warfare and migration, observed and interviewed for data collection. Content analysis was used to determine the themes present in the qualitative data. The themes identified in the drawings were discussed referring to the literature and recommendations were made.

Xenophobia, being hostile to foreigners and feeling fear of them, is considered as hating and having prejudices against the people of other nations. It is noticed that with the increase of migration movements on a global scale in recent years, xenophobia has become one of the more critical subjects in the scientific world. Determining the relationships between xenophobic attitudes and personal traits is considered as one of the important steps in developing relationships especially among people from different cultures. By detecting positive personality traits and negative personality traits associated with xenophobia, interpersonal relationships can be developed. Accordingly, in the current study, it is aimed to determine the relationships between xenophobia and personality traits (neuroticism, extraversion, openness to experience, agreeableness and conscientiousness, and Machiavellianism, narcissism and psychopathy). For this purpose, data were collected from 422 (342 females, 80 males) university students via the data collection tools, which are “Xenophobia Scale”, “Adjectives Based Personality Test” and “Dirty Dozen Scale”. The data were analyzed by stepwise regression technique. As a result of the analyzes, it has been observed that agreeableness, which is among the five-factor personality traits, and psychopathy and narcissism, which are among the dark triad-personality traits predicted xenophobia significantly. Accordingly, it was determined that the agreeable people had lower levels of xenophobic attitudes. Psychopathy and narcissism personality traits have been observed to lead to higher levels of xenophobic attitudes.

Digital storytelling has undergone extensive study in different content-areas, but its naturally-combined use with collaborative writing for skills development, and reflective practice remains underresearched in pre-service EFL teacher education. This study undertook joint tech-enhanced retelling of L2 texts by 56 Turkish EFL teacher candidates, rubric-based peer and teacher assessment of final products, comparative analysis of complexity, accuracy, and fluency (CAF) between outliers, and process evaluation using the significant learning taxonomy to explore impacts on L2 writing performance, academic learning, and personal growth. Despite assigning lower scores than the teacher-assessors, especially to the top-performers, the majority of peers successfully fulfilled the job, effectively performed the future reviewer role, and positively reacted to co-construction, and technology integration. CAF and reflection analyses indicated that the biggest difference between the highest- and lowest-scoring groups lay in grammatical accuracy, and lack of mutual interaction could account for the less cooperative group’s poorer performance. The classification of their post-task responses into six kinds of learning gains (foundational knowledge, application, integration, human dimension, caring, and learning how to learn) also revealed that their collaborative digital storytelling experience (CDS) elicited more procedural, critical, creative and practical thinking on the academic learning front, while disciplinary and integrative thinking may have declined due to more immediate preoccupation with task achievement. Their critical thinking was mainly organised around consensus-reaching, fluctuating membership, and logistical challenges, and most demonstrated a clear understanding of the role of positive group dynamics in group outcomes. Despite heightened awareness of the performance-boosting, character-forming, and motivational benefits of collective scaffolding and multimodal meaning-making, a minority could also discern the instrumentality of innovative teaching techniques in their future classroom practices.

The purpose of this study is to investigate the effect of Personalized Book Advice Smart Application on secondary school students’ motivation as well as determining the views of students, teachers, and parents regarding the application. In the research, a mixed method approach, in which quantitative analysis and qualitative analysis methods are used together, was adopted. In the quantitative part, 585 secondary school students, 300 of whom are in the experimental group and 285 in the control group; In the qualitative part, 105 students, 6 teachers and 247 families were included in the research. Similarly, the qualitative of the study involved 105 students, 6 teachers, and 247 parents. In the quantitative part of the research, data collected with the Reading Motivation Scale developed by Durmus. In the qualitative part, the data were collected through a questionnaire. The quantitative data were analyzed using parametric descriptive statistics, while the qualitative data were analyzed using descriptive analysis technique. According to the findings obtained from the research, there is a significant difference in reading motivation of secondary school students in terms of post-test scores. It is seen that the students like to read adventure books and think that the books proposed by the application are suitable for their interests. Teachers state that they find the application successful, and they like that the application forms reading habits, and recommends books according to their interests, moreover, the recommended books are suitable for the students’ levels. On the other hand, the teachers think that teacher control is necessary. Additionally, parents state that they like the application because it recommends books according to the children’s interests and those recommended books were suitable for their levels, however, they added that the number of the books needs to be increased.

The purpose of this study was to examine the relationship between effective communication skills and verbal intelligence levels of Faculty of Sports Sciences students according to variables such as gender, department, age, academic grade point average (GPA), and way of taking the Effective Communication Skills (ECS) course. The correlational survey model was used in the research. The subjects were 230 volunteer university students, chosen by simple random sampling method. The Multiple Intelligence Areas Inventory and The Effective Communication Skills Scale were used. The result showed that there was a significant difference in favor of female students in terms of effective listening by gender. A significant difference was found in favor of the Recreation Department in terms of self-recognition/self-disclosure, I-language, and verbal intelligence sub-dimensions. A significant difference was found in favor of 21-23 age in self-recognition/self-disclosure sub-dimension by age variable. According to academic GPA, a significant difference was found in the verbal intelligence sub-dimension in favor of those whose academic GPA was 3.15-3.57. In addition, according to way of taking the ECS course, a significant difference was found in favor of the compulsory course in the sub-dimensions of ego supportive language, self-recognition/self-disclosure, and I-language. Besides, it was determined that there is a positive and significant relationship between students' effective communication skills and verbal intelligence levels. As a result, it has been determined that, in terms of the development of communication skills, it is important that the ECS course is included in the curriculum as part of the compulsory course.

Shared leadership enables employees to develop positive feelings for their organizations and themselves. Especially, their devotional feelings and behaviours towards their organizations increase with the sharing of leadership. In this study, the shared leadership of the school and the organizational commitment levels of the teachers, their relationship with each other and the predictive status were examined. This study is a research within relational survey model. The data of the research were collected from 512 teachers in primary and secondary schools in Malatya districts of Turkey in the 2019-2020 academic year. The data were collected through the Shared Leadership Scale and the Organizational Commitment Scale of Teachers. For the analysis of the data, t-test, ANOVA test, correlation and regression analyzes were performed. According to the results of the research, shared leadership and organizational commitment levels in primary and secondary schools are high. There is a positively significant and moderate correlation between the shared leadership of the school and the organizational commitment of teachers. Shared leadership in primary and secondary schools positively and significantly predicts teachers' organizational commitment. For this reason, in order to increase the organizational commitment of teachers; it is important to create a sharing school life, in order to support teachers for the purposes of the organization and to include them in decision-making processes. According to the results obtained, it is recommended that young teachers with lower organizational commitment be given more duties, powers and responsibilities.

Progress monitoring of academic achievement is an essential element to prevent learning disorders. A prominent approach is curriculum-based measurement (CBM). Various studies have documented positive effects of CBM on students’ achievement. Nevertheless, the use of CBM is associated with additional work for teachers. The use of tablets may be of help here. Yet, although many advantages of computer- or tablet-based assessments are being discussed in the literature (e. g. innovative item formats, adaptive testing, automated scoring and feedback), there are still concerns regarding the comparability of different assessment modes (paper-pencil vs. tablet). In the study presented, we analyze the CBM data of 98 fourth graders. They processed the exact same computation items once with paper and pen and once in a tablet application. The analyses point to comparable results in the test modes, although some significant deviations can be found at item level. In addition, the children report perceived benefits when working with the tablet.

The aim of the present study is to examine the effect level of procrastination on academic achievement. To this end, a meta-analytic approach was applied and the studies published between January 2000 and May 2020 in Education Resources Information Center (ERIC) and Academic Search Ultimate databases were included in the study. The research was limited to articles examining the correlation between the variables and, accordingly, the correlation coefficient was specified as an index to identify the effect size. After reviewing 22 relevant studies with 8307 participants, the meta-analysis was conducted through Comprehensive Meta-Analysis (CMA) software. The findings revealed that the variables were negatively correlated with each other and the overall effect size of procrastination on academic achievement was found -0.61, which can be interpreted as the medium effect size. The findings of the study endorse the main tenets of theoretical framework regarding the aforementioned link.

This study was conducted to investigate prospective teachers' spiritual well-beings and life satisfactions in terms of specified variables. 298 students from various departments of universities participated in the study. The Spiritual Well-Being Scale developed by Paloutzian and Ellison, and adapted to Turkish by Eksi and Kardas, the Life Satisfaction Scale developed by Diener et al. and translated and adapted to Turkish by Koker and a Personal Information Form prepared by the researcher were used in the study. This study was a descriptive study based on survey model. The study data were subjected to normality tests and analyzed accordingly. Mann Whitney U Test, Kruskal-Wallis H Test and Spearman Rho correlation coefficient were used to analyze the data. Results of the study, indicated that spiritual well-being levels of prospective teachers significantly varied by gender, year of study, field of study and educational status of father. Life satisfaction levels of prospective teachers significantly varied by field of study. Furthermore, there was a moderate positive correlation between total score for spiritual well-being and life satisfaction.

The aim of this study is to identify whether high school students encounter any difficulties in mathematics and reveal the reasons for such difficulties. The participants of the study, which was a descriptive case study based on qualitative understanding, were a total of 164 students, including 85 students from Anatolian High Schools and 79 students from Science High Schools. Approximately 11% of the participants said they had no difficulties in math, whereas 99% of the students from Anatolian High Schools and 78% of the students from Science High Schools said they had difficulties in mathematic. Their thoughts about the reasons for such difficulties were analyzed by content analysis method considering the type of high school they attended. The findings obtained revealed that the difficulties encountered by the participants in mathematics were teacher-, content- and student-based. Anatolian High School students stated that they intensely faced teacher-based difficulties, whereas Science High School students stated that they faced content-based difficulties. It's expected that the results of this study may contribute to studies to be conducted to increase student success in mathematics education and provide ideas for further studies.

Revision constitutes an important component of the writing process that integrates text interpretation, reflection, and production. Although previous studies have offered useful insights into the revision behaviour of L2 writers at different levels of proficiency using off-line measures, little is known about the online processes of revision. In this study, I used keystroke logging to investigate longitudinal changes in the revision processes of postgraduate and undergraduate students in the context of an intensive English for Academic Purposes (EAP) program. Twenty-five postgraduate and 14 undergraduate students participated in this study. The keystroke logging program Inputlog was used during two essay writing sessions at the beginning and at the end of the course to observe how the participants revise their essays and to get insights into their on-line writing processes. Keystroke logging data were coded in terms of the orientation and location of revisions. The results revealed that postgraduates produced more content-oriented revisions at the end of the programme than at the beginning. The opposite trend was observed for the undergraduates, who revised their essays significantly less frequently at the end than at the beginning of the EAP program and made more mechanical revisions than postgraduate writers. The findings highlight fundamental differences in the developmental trajectories of revision processes between postgraduate and undergraduate students. These differences caused by previous academic writing experience and language proficiency should be considered in developing materials for EAP programs. In the paper, I also discuss benefits of using keystroke logging to investigate L2 writers’ revision processes.

This study investigated the link between future L2 selves and Willingness to Communicate (WTC) in the classroom in the UK university context. We applied a mixed methods approach to collect data from 121 Chinese overseas students where a questionnaire was used before semi-structured interviews were conducted with six participants. Two key quantitative findings were: 1) There is a strong positive correlation between ideal L2 self and classroom WTC; 2) A student’s major moderates the relationship between the ought-to L2 self and classroom WTC. Students from non-English-related majors had a greater influence of ought-to L2 self on their WTC in the classroom, while ought-to L2 self does not seem to affect the WTC of English-related majors in the classroom. Follow-up interviews triangulated the quantitative findings with further illustrations in terms of the role of future L2 selves in stimulating WTC in the classroom and the potential differences between students with different academic backgrounds.
