Learning analytics (LA) provides tools to analyze historical data with the goal of better understanding how curricular structures and features have impacted student learning. Forward-looking curriculum design, however, frequently involves a degree of uncertainty. Historical data may be unavailable, a contemplated modification to curriculum may be…

This article is devoted to the study of the possibilities of educational environment design in the arrangement of the schoolwork with children from migrant families so that they could positively adapt to the conditions of school and integrate into the culture of the host country. Based on a generalization of the problems faced by migrant children,…

Investigating symmetric dot patterns provides opportunities for foundational mathematical learning that is not restricted to multiplication alone. Students have opportunities to learn about the properties of symmetry, about the generalization of patterns, about writing and interpreting equations--all areas of study in grades 3-5. And symmetric dot…

This paper introduces "Kwaras" and "Namuti," two new tools for building, managing, accessing, and mobilizing ELAN-based language documentation corpora. Kwaras integrates WAV files, ELAN annotations, and document metadata into a web-based corpus, allowing immediate access to annotations and recordings. Namuti builds from Kwaras…

This document introduces, describes and exemplifies the technical features of some recently implemented automated reasoning tools in the dynamic mathematics software GeoGebra. The new tools are based on symbolic computation algorithms, allowing the automatic and rigorous proving and discovery of theorems on constructed geometric figures. Some…

Jeff McQuillan offers case studies of intermediate level language learners who read young adult and adult fiction successfully as an argument against explicit vocabulary instruction. Case studies provide useful insights into whatever is being investigated but may not always be generalizable. However, McQuillan's reference to case studies has made…

E-rater[R] is an automated essay scoring system that uses natural language processing techniques to extract features from essays and to model statistically human holistic ratings. Educational Testing Service has investigated the use of e-rater, in conjunction with human ratings, to score one of the two writing tasks on the TOEFL-iBT[R] writing…

Given three points in the plane, interest is in the locus of all points for which the sum of the distances to the given points is a prescribed constant. These curves turn out to be sixth degree polynominals in x and y , and thus are complicated. However, it turns out that often there is a point, within the triangle formed by the three given…

A heuristic description is given of the rediscovery with "Sketchpad" of a less-well-known, but beautiful, generalization of the nine-point circle to a nine-point conic, as well as an associated generalization of the Euler line. The author's initial analytic geometry proofs, which made use of the symbolic algebra facility of the TI-92 calculator,…

In this paper, the theory of variation in the tradition of phenomenographic research approach is placed in the context of Dynamic Geometry Environment (DGE). Central concepts of discernment, variation, simultaneity and space of learning in the theory of variation are discussed for simple dragging episodes in DGE to illustrate the potential…

This final report describes activities of a federally funded project which developed an educational computer-assisted instructional program for persons with severe disabilities. A preliminary review of the literature identified specific inadequacies of most software for this population, such as: too few examples of a task or concept thus limiting…

In all likelihood, currently employed therapists and teachers grew up with computer technology. Part of their computer culture included programming computers for entertainment using popular consumer software like Microsoft Basic. Within this social-educational milieu, the "FACTS+" curriculum represents one long-term project covering the…
