This article describes a systematic approach to subgroup classification based on a classification framework and sequential steps involved in the subgrouping process. The sequential steps are stating the purpose of the classification, identifying the classification elements, using relevant information, and using clearly stated and purposeful…

This paper attempts to examine in a descriptive way the pioneering model of "World Englishes" proposed by Kachru in the mid-1980s that allocates the presence of English into three concentric circles: The "Inner" Circle, the "Outer" Circle, and the "Expanding" Circle. The Inner Circle presents the countries…

We present a proposal for helping students to cope with statistical word problems related to the classification of different cases of confidence intervals. The proposal promotes an environment where students can explicitly discuss the reasons underlying their classification of cases.

The first intelligent tutoring systems for computer programming have been proposed more than 30 years ago, mostly focusing on well defined programming tasks e.g. in the context of logic programming. Recent systems also teach complex programs, where explicit modelling of every possible program and mistake is no longer possible. Such systems are…

For well over two decades, the OECD has developed and published a broad range of comparative indicators published yearly in the flagship publication Education at a Glance. These provide insights into the functioning of education systems, such as the participation and progress through education, the human and financial resources invested, and the…

We report our progress on the "River Memorial Museum" didactic intervention project developed with schools, in the basin of the Atoyac River in Mexico, that are significantly impacted by the pollution produced through industrialisation. The teachers of the elementary schools in these communities, environmental scientists, educators, and…

This Study Snapshot highlights key findings from a study that examined how attaining English proficiency and being reclassified as fluent English proficient affected achievement in English language arts and math in the first year after student reclassification in grades 3-8 in New Mexico. New Mexico established a state-level policy that requires…

A broad categorisation of different reading styles for mathematics text is generated in this research. The styles derive from those found in literature around academic reading skills. These styles are inductively refined using video transcripts of five specially chosen students studying out loud from a prescribed mathematics textbook. The context…

Coding is a process of assigning meaning to a given piece of evidence. Evidence may be found in a variety of data types, including documents, research interviews, posts from social media, conversations from learning platforms, or any source of data that may provide insights for the questions under qualitative study. In this study, we focus on text…

Principal component analysis (PCA) is one of the most important and powerful methods in chemometrics as well as in a wealth of other areas. Running a PCA results in two main elements, the score plot and the loading plot; the score plot provides the location of the samples, and the loading plot indicates correlations among variables, the trends in…

This study was prompted by the Arizona Department of Education's (ADE) interest in learning more about the progress of English learner students toward English proficiency in the early grades. The study examined, for the 2013/14 kindergarten cohort in Arizona, the English language proficiency of non-native English speaker students and their English…

Brian Martin describes a difficult committee meeting he once attended which consisted of one representative from each department. When the meeting ended it left a bitter taste for many who participated. Having learned from this experience, Martin became a chair of the committee and tried a new system that overcame many of the previous problems.…

Language Policy and Planning is currently a significantly diversified research area and thus it is not easy to find common denominators that help to define basic approaches within it. Richard B. Baldauf attempted to do so by differentiating between four basic approaches: (1) the classical approach, (2) the language management approach (Language…

Online educational videos have emerged as one of the most popular modes of learning in the recent years. Studies have shown that liveliness is highly correlated to engagement in educational videos. While previous work has focused on feature engineering to estimate liveliness and that too using only the acoustic information, in this paper we…

Professional knowledge is highlighted as an important prerequisite of both medical doctors and teachers. Based on recent conceptions of professional knowledge in these fields, knowledge can be differentiated within several aspects. However, these knowledge aspects are currently conceptualized differently across different domains and projects.…
