According to "noun-cue" models, arbitrary linguistic categories, like those associated with case and gender systems, are difficult to learn unless members of the target category (i.e., nouns) are marked with phonological or semantic cues that reliably co-occur with grammatical morphemes (e.g., determiners) that exemplify the categories. "Syntactic…

This article explores analogy as a communicative tool used by parents to relate children's past experiences to unfamiliar concepts. Two studies explored how similarity comparisons and relational analogies were used in parent-child conversations about science topics. In Study 1, 98 family groups including 4- to 9-year-olds explored two science…

This paper is about a study into the nature of analogies recorded from three Form 2 (Grade 10) classes in Kenya, instructed by three physics teachers. Through a case study method involving classroom observation, several analogies were recorded and analysed. These analogies were predominantly "environmental" (drawn from students'…

This article presents a critical review of complexity theory in relation to educational research. The "analytical reductionist" approach is one in which the educational researcher seeks to reduce complex wholes to particular factors and to identify correlations between them and desirable outcomes. Complexity theory shows how this approach in…

In this article we describe the initial investigations that we have conducted on student data collected from a web-based tutoring tool. We have used some data mining techniques such as association rule and symbolic data analysis, as well as traditional SQL queries to gain further insight on the students' learning and deduce information to improve…

The aim of this paper is to compare the effects of different communication media on the quality of arguments and the development of argumentative reasoning. The study involved 73 undergraduate students. It consisted of a pre-test, an intervention session consisting of either an asynchronous online discussion or a face-to-face discussion, and a…

This paper reports on a project that aimed to assist the induction of three women teachers into the practice of mathematics teaching. In their first year of teaching the three teachers were located in schools at great distances from the normal support structures for the teachers. Further, the schools consisted of student populations with wide…

The tendency to generalize from specific experiences leading to new, more abstract concepts is a natural aspect of human thought. Generalizations are the end result of an inductive process that begins with the identification of similarities in seemingly disparate situations. It is the existence of such generalizations that makes it possible for us…

Heuristic training alone is not enough for developing one's mathematical thinking. One missing component is a mathematical point of view. This study reports findings regarding outcomes of a historical approach calculus course to foster Taiwanese college students' views of mathematical thinking. This study consisted of 3 stages. During the initial…

Nondeterminism is an essential concept in mathematics and one of the important concepts in computer science. It is also among the most abstract ones. Thus, many students find it difficult to cope with. In this article, we describe some didactic considerations, which guided the development of a "Computational Models" course for high school…

Achieve launched this study to help inform the decisions states are making about high school assessments by providing greater insights into the world of college admissions and placement testing. Achieve analyzed more than 2,000 questions from college admissions and placement exams to determine how these tests compare to one another and how well…

Tests are intended to assess performance of students. However, tests can also be used as an educational tool. Current patterns in education have produced a group of students with weak learning skills, limited confidence in their own abilities, an underlying hostility or distrust of the educational system, and an inhibited attitude towards…

A new concept, relativistic operations, seems to provide a link between Piagetian theory, information processing theory, logical thought in the new physics, and the nature of adults' problem solving in everyday social situations. Relativistic operations are logical, cognitive operations which can be used as a system to relate, order, and select as…

Intended for elementary school language arts teachers, this paper outlines some recent work in the area of cognitive functioning and shows how this highlights the necessity for great care in fostering a child's language competence at two different stages: very early childhood and early to middle primary school. Following an introduction, the paper…

This study investigated the educational implications of having a group of 17 first-year New Zealand nursing students develop a medical expert system. Goals of the study were to determine whether, in the process of developing the expert system, the learners could: (1) acquire a more in-depth understanding of the specific subject domain under study…
