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 article introduces an entropy-based measure of data-model fit that can be used to assess the quality of logistic regression models. Entropy has previously been used in mixture-modeling to quantify how well individuals are classified into latent classes. The current study proposes the use of entropy for logistic regression models to quantify…

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 article presents a typology of statements that can be made about discourse data. The classification is based on two parameters: level of generality and level of interpretation. Each of these is operationalized into three discrete levels, to yield a nine-cell table containing types of statements going from the presentation of a single case to…

This paper presents the methods and outcomes of a typological analysis of Web 2.0 technologies. A comprehensive review incorporating over 2000 links led to identification of over 200 Web 2.0 technologies that were suitable for learning and teaching purposes. The typological analysis involved development of relevant Web 2.0 dimensions, grouping…

The aim of the research is to create the classification for shock wave triple configurations and their existence regions of various types: type 1, type 2, type 3. Analytical solutions for limit Mach numbers and passing shock intensity that define existence region of every type of triple configuration have been acquired. The ratios that conjugate…

Models of category learning have been extensively studied in cognitive science and primarily tested on perceptual abstractions or artificial stimuli. In this paper, we focus on categories acquired from natural language stimuli, that is, words (e.g., "chair" is a member of the furniture category). We present a Bayesian model that, unlike…

Purpose: The authors sought to determine an optimal set of flesh points on the tongue and lips for classifying speech movements. Method: The authors used electromagnetic articulographs (Carstens AG500 and NDI Wave) to record tongue and lip movements from 13 healthy talkers who articulated 8 vowels, 11 consonants, a phonetically balanced set of…

How do people learn categories and what changes with development? The current study attempts to address these questions by focusing on the role of attention in the development of categorization. In Experiment 1, participants (adults, 7-year-olds, and 4-year-olds) were trained with novel categories consisting of deterministic and probabilistic…

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…

Understanding identity labels as "jaulas" [cages] and testimonios as theory and method, this article centers bi/multilingual Latinx students' experiences in high school English Language Development (ELD) classes. We present how two teachers, now researchers, built long-term relationships with former elementary school students, affording…

Expression of motion shows systematic inter-typological variability between language types, particularly with respect to manner and path components of motion: speakers of satellite-framed languages (S-language; e.g. German) frequently conflate manner and path into a single clause, while verb-framed language speakers (V-language; e.g. Spanish)…

Non-governmental organizations (NGOs) are becoming increasingly important participants in educational programmes and implementing education policy. This study explores governmental policymakers' perceptions and reactions to NGO involvement in the implementation of education policy. We applied a qualitative research method, conducting in-depth…

I present my perspective on the design process in this article, arguing for a focus on student learning and "slow design" that stems from knowledge of mathematics and their support system in the learning process. I have a question about the design process academization and task design research direction. Numerous examples from my work at…

Citation is an essential part of academic writing and allows writers to make strong arguments, review previous research, and express their opinions. This study investigates reporting verbs as a part of citation practice in the research articles published in Iranian and international journals (with different linguacultural backgrounds) in…
