The development of a suite of computer-based diagnostic tests based on the Common European Framework

2005

DIALANG is an on-line language assessment system, which contains tests in 14 European languages and is based on the Common European Framework of Reference (CEFR). It is the first major testing system that is oriented towards diagnosing language skills and providing feedback to users rather than certifying their proficiency. This article describes the contents of Version 1 of DIALANG and the way in which the system works. This is followed by an account of the development of DIALANG tests and of the pilot testing and standard setting procedures. The results of the first analyses of items and self-assessment statements, and of the standard setting procedures, are reported. The article focuses…

Training with a computer-based simulator achieves basic manual skills required for upper endoscopy: A randomized controlled trial

2004

Changes in medical practice have constrained the time available for education and the availability of patients for training. Computer-based simulators have been devised that can be used to achieve manual skills without patient contact. This study prospectively compared, in a clinical setting, the efficacy of a computer-based simulator for training in upper endoscopy.Twenty-two fellows with no experience in endoscopy were randomly assigned to two groups: one group underwent 10 hours of preclinical training with a computer-based simulator, and the other did not. Each trainee performed upper endoscopy in 19 or 20 patients. Performance parameters evaluated included the following: esophageal int…

Computer‐based and Face‐to‐face Collaborative Argumentation in Secondary Schools in England and Finland

2005

Abstract This article focuses on the analysis of secondary school students’ argumentative interactions in England and Finland, within specific face‐to‐face and computer‐based environments. We propose that a combination of learning environments, in conjunction with teacher input and support, is important for developing argumentation skills in the classroom. Face‐to‐face argumentation, in particular, offers ample opportunity for concentrating on the quality (through deeper exploration) of arguments; such learning can enhance the construction of well‐structured arguments often associated with some computer‐based environments, such as synchronous computer chat.

New Technology, Writing And Learning

2001

The participants involved in most previous studies on writing have written their texts by hand but writing with the aid of a computer is much more prevalent today. This chapter specifically examines the effects of new technology on writing and, by implication, on writing to learn, and presents examples how technology has created new possibilities for using writing for purposes of learning. The chapter is divided into four main parts. Part one briefly introduces the chapter. Part two considers the nature of writing in terms of interactions between planning, writing and editing. Part three examines how computer aided writing changes these processes. Here individual and collaborative writing a…

Systematic Approach for Calculating the Concentrations of Chemical Species in Multiequilibrium Problems: Inclusion of the Ionic Strength Effects

2012

A general systematic approach including ionic strength effects is proposed for the numerical calculation of concentrations of chemical species in multiequilibrium problems. This approach extends the versatility of the approach presented in a previous article and is applied using the Solver option of the Excel spreadsheet to solve real problems such as the calculation of the pH of buffer solutions at any ionic strength. It is useful for undergraduate programs, in post-graduate programs, and in professional laboratories to predict experimental conditions.

Technological, Organisational and Socio-Interactional Affordances in Simulation-Based Collaborative Learning

2021

Analysis of the applicability of a learning technology requires an evaluation of how the affordances of the learning environment respond to users’ needs. We examine affordances in a simulation-based collaborative learning environment from the learners’ viewpoint. Our analysis focuses on three types of affordances: technological, organisational and socio-interactional. The findings show how teams of learners employ the different types of affordances in their collaborative tasks. In addition, our analysis illustrates the interdependent and interlinked nature of the affordances. We offer an analytical understanding of the dynamics among different kinds of affordances and show how they can be a…

Customization Support in Computer-Based Technologies for Autism: A Systematic Mapping Study

Autism Spectrum Disorder (ASD) is a neurodevelopmental condition characterized by social interaction and communication difficulties, along with narrow and repetitive interests. Being a spectrum dis...

Paper-based vs computer-based exams in CS1

2016

In this study, we examine the "test mode effect" in CS1 exam using the Rainfall problem. The participants started working with pen and paper, after which they had access to a computer, and they could rework their solution with a help of a test suite developed by the authors. In the computer- based phase many students were able to fix the errors that they had committed during the paper-based phase. These errors included well-known corner cases, such as empty array or division by zero.

Construction and validation of a computer-based diagnostic module on average velocity

1994

This article describes the process of building a computer-based diagnostic module concerning the understanding of the average velocity concept. The first step consists of the production of a student model that takes into account student errors and reasoning paths. The computer module formulates its diagnosis by leading users along different patterns foreseen according to the hypothesized student model. Results are reported concerning a correlation analysis between automatic and human diagnoses.
