Computer-Based Tools for Instructional Design: An Introduction to the Special Issue

Modern instructional theories are characterized by their focus on rich, multidisciplinary and often collaborative learning tasks that are somehow representative for authentic, real life tasks. This new view on learning heavily increases the complexity of the design process and the resulting instructional systems. It is argued that computer-based instructional design (ID) tools may help to deal ...

Introduction to the Special Issue on Computer Arithmetic

intensive numerical simulations use floating-point arithmetic operations, and elementary functions such as logarithm or cosine. Gaining speed and accuracy is tantamount in these applications; cryptographic applications use totally different calculations–but it is still a matter of arithmetic!–, to allow one to efficiently play with elliptic curves, integer lattices, and similar discrete structu...

Special Issue Introduction: Semantic Role Labeling: An Introduction to the Special Issue

Semantic role labeling, the computational identification and labeling of arguments in text, has become a leading task in computational linguistics today. Although the issues for this task have been studied for decades, the availability of large resources and the development of statistical machine learning methods have heightened the amount of effort in this field. This special issue presents se...

Introduction to Special Issue

Although recent frameworks for test validation have emphasized utilization as a key component (e.g. Bachman & Palmer, 2010; Chapelle, 2012; Kane, 1992), what happens in the sometimes messy contexts where assessments are carried out is often not documented. This is perhaps because test developers are more focused on defining and operationalizing test constructs than on issues of implementation. ...
