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.

Many educators hold beliefs that including students, at least to some degree, has academic and social benefits, however, they struggle with fundamental pedagogy. With a global shift from a segregated lens to that of an inclusive lens, special education teachers who once held positive beliefs towards segregated special education are now faced with a new reality of teaching students with disabilities in inclusive classroom settings. This paper highlights the experiences of ten educators who transitioned from teaching in a self-contained class to an inclusive class. Focus group and interview themes indicated that all had experienced a shift in their pedagogy- their overall beliefs and teaching methods- after they taught students with disabilities in inclusive classrooms. Despite their special education training, these educators were challenged by their own beliefs and expectations, the attitudes of others, and systematic barriers within the education system. Highlights of their change process include the positive performance of students with disabilities, the growth and development of the other students, and their overall pedagogical self-reflection. As a result, a framework, the Inclusive Educators’ Continuum of Change, was developed to highlight the change process and connect this research to the literature on inclusion and teacher change. This diagram can provide teacher educators a framework for discussing pedagogical change. Implications for professional development and teacher training for inclusive practice, as well as maximizing the educator skills in Professional Learning Communities (PLC) and mentorship opportunities will be highlighted.

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.

Motivation for school is an important concept which influences students’ academic, social and cultural development. Leadership behaviours to be displayed by school principals can be thought to affect the network of social relations in school and to support the climate of trust in school for students to develop positive attitudes towards the school. In this context, this paper aims to analyse the correlations between school principals’ social justice leadership behaviours, students’ trust in school principals and motivation for school. The study group was composed of 762 secondary school students from Altindag district of Ankara. The data were collected with social justice leadership scale, trust in the school principal scale and motivation for the school scale. The data were put to descriptive analysis, correlation analysis and multiple linear regression analysis. The findings demonstrated that students had moderate level of perceptions of school principals’ social justice leadership behaviours and trust in school principals and high level of motivation for school. Besides, significant correlations were also found between the variables. Additionally, it was found that social justice leadership predicted significantly trust in school principals and motivation for school. The findings showed that the social justice leadership behaviors of the school principal play a key role on students’ motivation and their trust in the principals.

The purpose of the study is to examine pre-service teachers' impromptu speaking skills on the basis of the evaluations of the instructor, peers and their own. The study employed a descriptive case study design, one of the qualitative research methods. A total of 23 pre-service math teachers taking the course of Art of Effective Speech in a state university in Turkey in the 2016-2017 academic year participated in the study. The data of the study were collected through the observations of the researcher and pre-service teachers. Descriptive analysis was used in the analysis of the data. As a result of the study, it was found that in most of the observation items, the pre-service teachers found themselves inadequate in terms of impromptu speaking skills while they were found to be adequate by their peers and instructor. In addition, it was revealed that the pre-service teachers found themselves inadequate in some items related to the use of voice while they found themselves adequate in most of the items related to articulation/diction and body language and in all of the items related to communication. However, while the instructor observed that the pre-service teachers were generally competent in all the sub-dimensions, she determined that they needed improvement in the sub-dimensions of eye contact, pausing at the appropriate place and speaking without repeating words.  

The research aims were to examine the relationship among psychological resilience, patience, and happiness levels of physical education teachers employing in İzmir, Afyonkarahisar, and Muğla provinces in the Aegean Region and was to explain whether psychological resilience and patience levels predict happiness. The research was a descriptive study in the relational scanning model. The study participants consisted of 336 PE teachers, 182 (54.2%) were males, and 154 (45.8%) were females.. The data were obtained using the Brief Resilience Scale (BRS), Patience Scale and Oxford Happiness Questionnaire. In the analysis of data were used SPSS 25 statistical program. The analysis of the data descriptive statistics, correlation, and statistical regression methods were used. As a result of the research, it was determined that the psychological resilience, patience, and happiness levels were at medium levels according to the average score the PE teachers got from the scales. It was found that there is a moderate positive relationship between PE teachers' psychological resilience, patience, and happiness levels, and psychological resilience and patience levels are a significant predictor of happiness.

In modern times, the importance of education cannot be overstated. Beyond the acquisition of knowledge, perhaps the most important aim of education may be the development of character in individuals, including vitality, courage, sensitiveness, and intelligence, from which our society may experience increased prosperity, peace, and freedom. In this paper we address the daunting challenge of achieving successful, widespread, and inclusive university education. How do we enliven and engage the students in our classrooms? How can we help each and every student in the class self-actualize and reach the highest potential for learning? Active learning is one well-established and potent solution for accelerating the accumulation of knowledge. In this paper, an experiment in active learning utilizing team-based adaptive online quizzes in an introductory math finance course involving 378 undergraduate students over two years is conducted to explore the potency of this active learning methodology compared to a control group with traditional teaching. We find active learning unambiguously improves knowledge accumulation in the individual students, while simultaneously bolstering inclusive excellence across all students in the class, as measured by a relevant and meaningful quantitative metric. The paper concludes with a discussion comparing the quality of active vs. traditional teaching methods and offers interpretations of the quantitative results. The results of this paper support the widely accepted theme in the literature that active learning has a positive effect on student performance in STEM (Science, Technology, Engineering, and Math) courses.

This study aims to determine the opinions of high school principals on their cultural intelligence levels, to determine the activities of these principals to increase their cultural intelligence levels, the advantages of their having a high level of cultural intelligence, the factors that prevent them from increasing their cultural intelligence levels, and their suggestions to increase their cultural intelligence levels. The data obtained from the interview forms were analyzed by the content analysis method. The findings were organized and presented under themes and sub-themes. The study group of the research consisted of 40 school principals working in Mersin central districts in the 2020-2021 academic years. According to the study results; most of the participants stated that they had a high level of cultural intelligence while some participants stated that they had a low level of cultural intelligence. Regarding the activities to increase their level of cultural intelligence, principals stated that they did activities such as increasing their knowledge, going abroad, and developing social relations. The principals expressed three different opinions on the advantages of having a high level of cultural intelligence: organizational advantages, professional advantages, and individual advantages. It was determined that factors preventing principals from increasing their cultural intelligence levels were factors unrelated to principal and factors related to principal. The principals expressed two different opinions on what could be done to increase their cultural intelligence levels: The things to be done by the superiors and the things to be done the principal.

The study discussed in this paper is a systematic literature review related to the role of dual language programme (DLP) in mathematics education which has been published within the last 5 years. This study was conducted to identify the distribution of DLP studies in terms of year of publication, the study context covered in previous studies, the context of study areas used, focus and trends of past studies, research methods used in previous studies and the role of language in school mathematics education. This review study followed the guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) to analyze articles from Scopus and Web of Science. The findings of the study indicate that research trends in the implementation of the DLP on mathematics education for secondary school students showed an increase from 2017 to 2019. Most DLP-related articles are widely developed in the United States and Germany. The findings indicate that previous studies are more interested in studying the implementation of DLP in rural areas. Past studies have also preferred to use the design of either a qualitative study or a quantitative study to be implemented. Questionnaires, tests and interviews are among the research instruments that are often used for a study.

Gamification in education refers to the application of game design elements and game principles in teaching with the goal of increasing students’ motivation and engagement, which contributes to more successful achievement of learning outcomes. Gamification can be used in education at different levels, from primary and secondary schools to universities and adult education. An analysis of the literature on the use of gamification in education has shown that it is more common in university education and less common in primary and secondary schools. Nonetheless, experience shows that games and numerous digital tools are successfully used in schools for the purpose of gamification, although this is generally not supported by the relevant research published in the papers. The research presented in this paper represents a systematic review of the literature on relevant research on the use of gamification in primary and secondary schools to explore the field and make recommendations for future research. The conclusion is that research on gamification should continue to suggest appropriate pedagogical and technological frameworks which would facilitate the use of gamification in schools by teachers.

Teachers face situations that are difficult to solve, which affect their practices in the classroom. Teachers´ability to face problematic situations been related to educators' adaptive and metacognitive capacity. This study aimed to contrast the recent literature on classroom problems with reports from Chilean teachers regarding what they mean today as critical situations in the classroom. The major problems with the highest prevalence were categorized based on a literature review. Subsequently, teachers from three educational levels (pre-school, primary and secondary) were asked to relate situations in which they had experienced a crisis in their profession. After a filtering based on the relevance and textual richness present, the stories (n=145) were subjected to a thematic analysis and contrasted with the categories obtained from the reviewed literature. The results show a low proportion of problems associated with learning management in the classroom and, on the other hand, a high proportion of behavioral problems in students focused on situations of aggression towards the teacher. These conclusions are discussed to reconsider the concept of "classroom problem situations" and, based on this, questioning the role of teacher training in the development of skills for the management of authentic problem situations.

The definition of creativity among professional mathematicians and the definition of mathematical creativity in the classroom context are significantly different. The purpose of this study was to investigate the relationship between students’ mathematical creativity (i.e., cognitive flexibility) and figure apprehension when solving geometric problems with novel auxiliary features such as straight lines and curved lines. In other words, this study determined if geometry knowledge influenced mathematical creativity (cognitive flexibility) in problem-solving. Grade-12 students participated in the intervention. The high school that is the research topic attempts to equip students with academic abilities and is, except for vocational schools, the most popular form of high school among all other types. Such a school was chosen for the study so that a significant proportion of students in Makassar could be represented. In this study, we discovered a relationship between cognitive flexibility and the geometric ability of pupils while solving problems involving auxiliary lines. This indicates that the usage of auxiliary lines as a reference for developing pupils’ creative thinking skills must be advocated. In addition, good geometric abilities (e.g., visual thinking, geometrical reasoning) will encourage pupils to generate various problem-solving concepts. This finding contributes significantly to future research by focusing on auxiliary lines.

This study explores the impact of gender on the preferred English language learning strategies of self-perceived introverted students in Vietnam, given the burgeoning role of English as an international lingua franca. A mixed-methods approach, involving survey questionnaires and follow-up interviews, was utilized to gather both quantitative and qualitative data from a cohort of 68 English major undergraduates, 29 of whom self-identified as introverted via the Myers-Briggs Type Indicator (MBTI). The investigation provides a comprehensive understanding of the preferred language learning strategies among introverted learners, and specifically examines how gender influences these strategic choices. The results reveal that gender does not present significant differences in the preferred English language learning strategies of self-perceived introverted individuals. Regardless of gender, introverted language learners demonstrate a tendency towards compensation learning strategies, with specific strategies such as deductive reasoning, organizing physical environs, and error rectification receiving almost identical responses from both male and female participants. These findings suggest that the role of personality traits, such as introversion, should be considered in tailoring pedagogical approaches to meet individual learning preferences and needs. Further research is needed to explore this area in greater depth and to examine its broader implications for English language teaching pedagogy.

The role of artificial intelligence (AI) in education remains incompletely understood, demanding further evaluation and the creation of robust assessment tools. Despite previous attempts to measure AI's impact in education, existing studies have limitations. This research aimed to develop and validate an assessment instrument for gauging AI effects in higher education. Employing various analytical methods, including Exploratory Factor Analysis, Confirmatory Factor Analysis, and Rasch Analysis, the initial 70-item instrument covered seven constructs. Administered to 635 students at Nueva Ecija University of Science and Technology – Gabaldon campus, content validity was assessed using the Lawshe method. After eliminating 19 items through EFA and CFA, Rasch analysis confirmed the construct validity and led to the removal of three more items. The final 48-item instrument, categorized into learning experiences, academic performance, career guidance, motivation, self-reliance, social interactions, and AI dependency, emerged as a valid and reliable tool for assessing AI's impact on higher education, especially among college students.
