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.

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 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).

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.

Classroom interaction is an essential element in developing communicative skills. In a foreign language context like Burkina Faso, the classroom appears as the only setting that provides an opportunity for English language learners to practice their communicative skills. In the classroom, teachers create opportunities for interaction between students and their peers, between students and teachers, and between students and teaching materials. Although those interactions are expected to promote English language acquisition, they sometimes seem insufficient. In this paper, the author examines the interactions between teachers and their students. The author seeks to understand the extent to which they can be conducive to communicative skills. The methodology used to collect this data is qualitative, mostly based on classroom observation and interviews. The participants are high school classroom teachers and their students. The results unveiled that the nature of the interaction was determined by the control and elicitation techniques used by teachers which often limited the opportunities to communicate.

Adversity Quotient is a person's response to overcoming obstacles or problems. Barriers experienced, and the ability to overcome these obstacles vary in each person. This study was a literature review study focusing on adversity quotient in the field of education. This study reviewed several manuscripts that concentrated on research design, type of participants, and the critical role of adversity quotient in the field of education. A total of 18 articles were analyzed by exploring and reviewing manuscripts from trusted database journals, namely Scopus, Science Direct, and ERIC. This review explored three aspects of educational adversity quotient publications, including 1) the type of research design used in research related to adversity quotient in the field of education, 2) the types of participants chosen in research related to adversity quotient, and 3) the role of adversity quotient in education. Based on the results of manuscript reviews, adversity quotient research shows a great influence in the field of education. Research on adversity quotient shows that 1) descriptive and experimental research is the most commonly used design; 2) research participants in adversity quotient research are dominated by students, especially university students; 3) the role of adversity quotient is much shown in learning outcomes in the field of skills.

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.

This study was designed to investigate the applicability of the IES/NSF pipeline-of-evidence protocol in ascertaining why two notable educational initiatives spearheaded and financially supported by the Bill and Melinda Gates Foundation achieved or not the goal of improved academic outcomes for K-12 public school students. Our interest was not whether there is a sufficient body of high quality research evidence to support the two initiatives but whether the research considered by the Gates Foundation established the likelihood that the initiatives would be successful and worth the decision to dedicate substantial funding, time, and effort required for each versus the many competing programs seeking sponsorship. We found that in the case of Intensive Partnerships for Effective Teaching, efficacy and effectiveness research were absent and the Gates foundation discontinued grant support because the initiative had not achieved the goal of improved high school graduation and college attendance among low-income minority students. In the case of Early College High School, we found empirical evidence was manifest at all but the effectiveness stage of the pipeline and the initiative continued to receive funding. Our findings support the importance of widening the net of methodologies that constitute a framework for elements needed to make predictions of effectiveness for any given intervention before investing in scale-up initiatives and the need for private foundations to be transparent in their decision-making process to enable others to scrutinize the research that informs the design of initiatives.

Decline in students’ motivation to learn languages remains a vexing issue for teachers and educators. Among a myriad of factors that affect student motivation, teachers’ practices appear to play a very dominant role. This has been reflected in the rising number of studies that examine teachers’ motivational strategies. This study aims to determine the specific teacher strategies which are most likely to positively affect the motivation of Arab learners of English from the perspective of learners. Some 400 teenage learners of English responded to an open-ended question in which they were asked to freely describe the strategies their teachers used that motivated them to learn. The results of the study suggest that the majority of students prefer strategies that promote communicative uses of the language to ones that focus on grammar or emphasize learning through texts. Many students also reported that they had more interest in studying English when their teachers integrated technology. It is therefore recommended that teachers give more weight to these motivating strategies by incorporating more communicative use of English and more technology into their lessons.

The goal of the study is to reveal the effect of activity-based media education on students' critical media literacy levels. A case study with fifth grade students was used in the study. A total of 18 students from a public school were participants. The data was gathered by a rubric and semi-structured interviews. Findings revealed that students have media literacy ability. Based on the result of the study, it can be suggested that either an independent media literacy course or a media literacy education integrated into other courses should be provided from the first grade. Furthermore, because of the fact that media literacy is closely related to critical thinking, teaching methods and activities in which students can gain critical questioning and thinking skills should be preferred.

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 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.

Contemporary studies related to teacher autonomy mostly deal with research into how autonomy is perceived by teachers and which variables it is associated with. On the other hand, there are very few studies dealing with how teachers’ instructional autonomy over the curriculum is reflected in the education process. The aim of this study is to reveal in depth the practices carried out in the context of instructional autonomy by science teachers who have different levels of autonomy. The study is based on data gathered from eight teachers employed at different schools in the province of Izmir in Turkey. Interviews, observations and documents were used for collecting the data. The results reveal that while teachers with high instructional autonomy successfully apply contemporary teaching methods, alternative evaluation techniques, high-order thinking skills and effective classroom management, teachers with low instructional autonomy fall short in all of these areas.

Although Goodman–Kruskal gamma (G) is used relatively rarely it has promising potential as a coefficient of association in educational settings.  Characteristics of G are studied in three sub-studies related to educational measurement settings. G appears to be unexpectedly appealing as an estimator of association between an item and a score because it strictly indicates the probability to get a correct answer in the test item given the score, and it accurately produces perfect latent association irrespective of distributions, degrees of freedom, number of tied pairs and tied values in the variables, or the difficulty levels in the items. However, it underestimates the association in an obvious manner when the number of categories in the item is more than four. Towards this, a dimension-corrected G (G2) is proposed and its characteristics are studied. Both G and G2 appear to be promising alternatives in measurement modelling settings, G with binary items and G2 with binary, polytomous and mixed datasets.

This paper investigated how puppetry could be used to improve the standards of early childhood science education. This study determined the effect of a puppet-making and puppetry workshop on preservice preschool teachers’ beliefs and attitudes towards science education and looked into their experiences during and after puppet-making. Although participants faced some difficulties during the workshop, they developed numerous socioemotional skills. Puppetry activities can help preservice teachers learn how to deliver child-centered, stimulating, and interactive classes. Using puppets in early childhood science education can help teachers develop positive attitudes towards science and offer students high-quality, engaging, and creative activities.

This article introduces the concept of the carrying capacity of data (CCD), defined as an integrated, evaluative judgment of the credibility of specific data-based inferences, informed by quantitative and qualitative analyses, leavened by experience. The sequential process of evaluating the CCD is represented schematically by a framework that can guide data analysis and statistical inference, as well as pedagogy. Aspects of each phase are illustrated with examples. A key initial activity in empirical work is data scrutiny, comprising consideration of data provenance and characteristics, as well as data limitations in light of the context and purpose of the study.  Relevant auxiliary information can contribute to evaluating the CCD, as can sensitivity analyses conducted at the modeling stage. It is argued that early courses in statistical methods, and the textbooks they rely on, typically give little emphasis to, or omit entirely, discussion of the importance of data scrutiny in scientific research. This inattention and lack of guided, practical experience leaves students unprepared for the real world of empirical studies. Instructors should both cultivate in their students a true respect for data and engage them in authentic empirical research involving real data, rather than the context-free data to which they are usually exposed.

The study aims to analyze, in terms of content and process, the math talks between the mother and child during the shared book reading of the illustrated storybooks with math contents. The study group under the research is comprised of nine pairs of mother and child. The process of the study 18 videos which were recorded when two storybooks with math contents were read by the mothers. In the data collection process, each pair of mother and child together read two storybooks given to them in their home environment, and the entire process was video-recorded. Subsequently, interviews were held with mothers for identifying their views about supporting their children’s math skills. It was shown that the content of mother-child math talks in the home environment was mostly about the learning area of numbers and counting skills. It was a remarkable result that math concepts such as sorting/ranking and properties/features of objects were not in the contents of mother-child math talks. The results from interviews with mothers, it was inferred that the mothers viewed themselves as inadequate for talking to their children about math concepts, and performed the math talks mostly on the basic skills such as counting the numbers.

In this article, we present some core ideas underpinning research that takes a Designs for Learning (DFL) approach guided by theoretical considerations and choices, as well as by practitioners’ challenges and inquiries. These choices shape, and are shaped by, DFL’s research goals and motives, theoretical orientation, research objectives, questions, and practitioners’ participation and ethical considerations. Further, we present and discuss how DFL as a research approach compares to other design-oriented research strategies. Even if a DFL research approach shares several similarities with other approaches of inquiry, we argue that it remains primarily oriented towards knowledge areas that relate to understanding and developing learning and teaching – both in formal education and in informal settings such as museums.
