Asynchronous Learning Networks (ALNs) make the process of collaboration more transparent, because a transcript of conference messages can be used to assess individual roles and contributions and the collaborative process itself. This study considers three aspects of ALNs: the design; the quality of the resulting knowledge construction process; and cohesion, role and power network structures. Th...

An onolysis of student learning with the LISP tutor indicates thot while LISP is complex, learning it is simple. The key to factoring out the complexity of LiSP is to monitor the leorning of the 500 productions in the LISP tutor which describe the progromming skill. The learning of these productions follows the power-low learning curve typical of skill acquisition. There is transfer from other ...

Questionnaires to assess goal orientation are widely used. However, recent research indicates some shortcomings. Most significantly, questionnaire data are unable to capture developments and changes in students ́ goal orientation during the learning process. Therefore, it seems appropriate to supplement questionnaire data with online measures that directly tackle students’ behavior. We analyzed ...

Turbinia-Vyasa is a computer-based instructional system that trains operators to troubleshoot and diagnose faults in marine power plants. The simulator, Turbinia, is based on a hierarchical representation of subsystems, components, and primitives. Vyasa is the computer-based tutor that teaches the troubleshooting task using Turbinia. The simulator, an interactive, direct manipulation interface,...

We present an automated detector that can predict a student’s later performance on a paper test of preparation for future learning, a post-test involving learning new material to solve problems involving skills that are related but different than the skills studied in the tutoring system. This automated detector operates on features of student learning and behavior within a Cognitive Tutor for ...

Teacher trainers/educators play a key role in the process of normalisation, as defined by Bax (2003), in the training of foreign language teachers to use technology as a regular part of their practice. This study explores teacher trainer attitudes towards adopting technology, their readiness to use it on teacher training courses, and their current levels of comfort in integrating it on Cambridg...

Cognitive tutoring systems have proven to be effective at improving mathematics learning in economically developed countries, but little is known about how teachers and students use these systems in other cultures. We visited three Latin American countries and observed use of the Middle School Mathematics Tutor in a school in each country. We found that students in these classrooms tended to wo...

model or time remaining. The planner is designed to be generic to tutors that teach troubleshooting for complex physical devices. It controls the Lower Hoist Tutor, a prototype tutor for the Mark-45 naval gun mount. This tutor teaches troubleshooting of the lower hoist, a complex hydraulic-electronic-mechanical assembly of the Mark-45 The tutor implementation demonstrates the planner’s operatio...

For cross-pollination between ITS authoring tools, it may be useful to know the prevalence of tutoring behaviors crafted with these tools. As a case study, we analyze the problem units of Mathtutor, a web-based intelligent tutor for middle-school mathematics built, as an example-tracing tutor, with the Cognitive Tutor Authoring Tools (CTAT). We focus on tutoring behaviors that are relevant to a...

Much of the power of a computer tutor comes from its ability to assess students. In some domains, including oral reading, assessing the proficiency of a student is a challenging task for a computer. Our approach for assessing student reading proficiency is to use data that a computer tutor collects through its interactions with a student to estimate his performance on a human-administered test ...
