Writing to Learn Mathematics: A Mixed Method Study
This study sought to address a research gap by studying students who had been taught mathematics using writing. The purpose of this study was to provide an analysis of students’ perceptions of the benefits and drawbacks of this pedagogical approach. The types of writing students performed in mathematics classes were described, and students’ preferences regarding these tasks were analyzed. Finally, a comparison was made between female and male students’ responses in order to see whether gen

Dealing with abstraction: case study generalisation as a method for eliciting design patterns
Developing a pattern language is a non-trivial problem. A critical requirement is a method to support pattern writers with abstraction, so as they can produce generalised patterns. In this paper, we address this issue by developing a structured process of generalisation. It is important that this process is initiated through engaging participants in identifying initial patterns, i.e. directly dealing with the 'cold-start' problem. We have found that short case study descriptions provide a produc

Exploring Teachers’ Beliefs through Collaborative Journaling: A Qualitative Case Study of Japanese
This qualitative case study was implemented to describe, interpret, and document preservice EFL teachers’ learning processes through collaborative journaling and gained awareness for all participants (including myself as a participant-observer). Four preservice EFL teachers in Japan (two males and two females) participated in the study. At the time of the investigation, they were all undergraduate students studying in an EFL teacher education program at a Japanese university. To investigate th

Promoting Different Kinds of Learners towards Active Learning in the Web-Based Environment
According to many recent studies the effect of learning style on academic performance has been found to be significant and mismatch between teaching and learning styles causes learning failure and frustration. Thus balancing the teaching style and the students' learning style is very important. When emphasizing the individual learning processes, web-based learning offers a good opportunity for differentiating ways of learning. So far the aim of this study is to describe different learners (categ

Turtle's Navigation and Manipulation of Geometrical Figures Constructed by Variable Processes in a 3
Issues related to 3d turtle's navigation and geometrical figures' manipulation in the simulated 3d space of a newly developed computational environment, MaLT, are reported and discussed here. The joint use of meaningful formalism and the dynamic manipulation of graphically represented 3d figures seem to offer new resources and to pose new challenges as far as geometrical activities and construction of meanings are concerned, which are strongly related to the representational infrastructure of Ma

Why Web 2.0 is Good for Learning and for Research: Principles and Prototypes
The term "Web 2.0" is used to describe applications that distinguish themselves from previous generations of software by a number of principles. Existing work shows that Web 2.0 applications can be successfully exploited for technology-enhance learning. However, in-depth analyses of the relationship between Web 2.0 technology on the one hand and teaching and learning on the other hand are still rare. In this article, we will analyze the technological principles of the Web 2.0 and describe thei

Adding new Representations of Mathematical Objects to Aplusix
In the framework of the ReMath European project, we initiated two new representations for algebraic expressions in Aplusix: a Tree & Natural representation mixing tree representations and natural representations of algebraic expressions, and a graphical representations to show curves and sets of solutions. Our work has been driven by two approaches: (1) a traditional approach focusing on the definition of new objects with their functionalities, beginning with a specification phase and continuing

A Bayesian Student Model without Hidden Nodes and Its Comparison with Item Response Theory
The Bayesian framework offers a number of techniques for inferring an individual's knowledge state from evidence of mastery of concepts or skills. A typical application where such a technique can be useful is Computer Adaptive Testing (CAT). A Bayesian modeling scheme, POKS, is proposed and compared to the traditional Item Response Theory (IRT), which has been the prevalent CAT approach for the last three decades. POKS is based on the theory of knowledge spaces and constructs item-to-item gra

Collaborative learning - New learning models and applications
Distance education – defined as education that takes place when the learner and the instructor are in separate location – is undergoing changes throughout the world. The teaching environment is undergoing a major shift as more and more programs are offering classes online. This shift is due to rising costs in education, enrollment management issues, and an evolution in the use of distance learning.

A New Analytical Approach on Continuous Improvement Evaluation: A National Presentation Case
This paper demonstrates a new approach on how to analyze evaluation data to find a team’s (sometimes called circle) improvement ability and the characteristics of evaluators by using the data from the national Quality Control Circle (QCC) presentations in Taiwan. Most evaluations on the QCC presentation use the itemized rating method or the duplex-pole evaluation method. The former has the negative effects of canceling out the higher and lower while the latter cannot distinguish the ability typ
