The Cognitive Tutor Authoring Tools (CTAT) [1] are a suite of software programs meant to make the creation of web-based ITS practical for non-programmers. CTAT supports a relatively novel type of tutors, called example-tracing tutors, which use examples of problem-solving approaches to assess and guide students as they practice solving problems. CTAT employs a programming-by-demonstration paradigm...
Although educational games can be engaging and motivating for students, the game aspects tend to take up time that could have been used for instruction, and they add to the cognitive load of the students. Therefore, instead of completely integrating educational content into a game framework, we instead choose to start with a computer tutor and selectively incorporate those features of games that are...
In this interactive demo we will present the Adaptive eLearning Platform – a web-based solution for the development, deployment and analysis of Adaptive Tutorials. Adaptive Tutorials (AT) are online instructional activities that exhibit three levels of adaptivity: students experience adaptive feedback with remediation targeted to their intrinsic misconceptions, while their activities are also sequenced...
In previous work, we developed SlideTutor - an Intelligent Tutoring System that teaches visual classification problem-solving in Pathology, and shown that use of the system is associated with rapid learning gains. Development of the SlideTutor system and content has required many years of effort by system developers, knowledge engineers and domain experts. Both cases and domain ontologies must be...
This demonstration will present a novel community environment ‘AWESOME Dissertation Environment (ADE)’ which uses semantic wikis to implement the pedagogical approach of ‘social scaffolding’. ADE was developed within an interdisciplinary UK research project called AWESOME (Academic Writing Empowered by Social Online Mediated Environments) which involved the universities of Leeds, Coventry and Bangor...
This demonstration will show how a tutor can detect the content of collaborative behavior and offer relevant domain level interventions. Rashi is a domain independent intelligent tutor providing students with practice using inquiry skills. When working on human biology, students interact with a virtual sick patient whom they must successfully diagnose. Rashi supports students as they create hypotheses...
We present our computer-based learning environment, Science Assistments (http://users.wpi.edu/ sci_assistments/; NSF-DRL # 0733286; NSF-DGE #0742503; U.S. Dept of Ed. # R305A090170), for Physics, Life Science, and Earth Science that scaffolds middle school students’ scientific process skills, namely, hypothesisgeneration, design of experiments, data collection, data interpretation, and warranting...
Mixing worked-out examples with problem solving has been shown to be an effective blend of educational activities [1]. Given the positive impact on learning, some Intelligent Tutoring Systems attempt to incorporate worked-out examples into their learning environments. The approach taken by Carnegie Learning’s Cognitive Tutor, called Interactive Examples, was created to solve two design challenges.
Two of the most important characteristics to support learning of geometric concepts are (a) the possibility of allowing students to interact with geometric objects and (b) the capability of guiding these students during the process of interaction by helping them to discover interesting properties and to make “plausible” conjectures. Available interactive/dynamic geometry software allow for rich interaction...
There is a need for software that supports learners in actively dealing with theoretical concepts by having them create models and perform concept prediction and explanation (e.g. [3,4,5]). DynaLearn seeks to address this by developing a domain independent Interactive Learning Environment (ILE) based on Qualitative Reasoning (QR) [1]. The QR vocabulary fits the nature of conceptual knowledge, and...
The effect of tutor learning has been studied in various contexts, providing ample evidence to suggest that students learn when they teach others. Yet, the cognitive and social factors that facilitate or inhibit tutor learning are still not well understood. One factor that prohibited research progress in this area is that studying the tutor learning effect could often be done only at the cost of tutees’...
Step-based ITS have been proven successful for well-defined domains, particularly in well-defined tasks, but their success is mitigated by their cost. Typically, the main factor behind the cost is the efforts needed to model the task domain. Different approaches have been investigated to reduce these efforts: Model-Tracing Tutors (e.g. Cognitive Tutors, Andes), Constraint-Based Tutors (e.g. SQL-Tutor,...
Project LISTEN’s Reading Tutor listens to children read aloud, and helps them learn to read, as illustrated on the Videos page of our website. This Interactive Event encompasses both this basic interaction and new extensions we are developing.
Carnegie Learning’s Cognitive Tutors for mathematics have been the subject of a wide variety of research [3,4] and are the most widely deployed Intelligent Tutoring Systems. Currently, over 560,000 students and 2,700 schools in all 50 United States are using them. Many ITS researchers understand these tutors from printed works but have not had the opportunity to use the tutors in a hands-on fashion.
Geometric proof has long been a topic of study within Intelligent Tutoring Systems [3,4]. Proof is interesting because it supports a variety of solutions and strategies. However, implementation is challenging and such tutors have not been widely deployed.
ISLET is a multiplayer role-playing game whose goal is to help players develop intercultural communication skills for French-speaking Sub-Saharan Africa. Its vision is to utilize multiplayer gameplay to create the most compelling language learning environment available.
The Pittsburgh Science of Learning Center’s DataShop is an open data repository and set of associated visualization and analysis tools. DataShop has data from thousands of students deriving from interactions with on-line course materials and intelligent tutoring systems. The data is fine-grained, with student actions recorded roughly every 20 seconds, and it is longitudinal, spanning semester or yearlong...
This interactive event presents a pressure sensitive chair constructed out of Wii Fit game controller boards. During this event, we will demonstrate how to arrange the boards to detect seat and back pressure, configure a PC to receive a bluetooth datastream from the boards, and modify the power supply of the boards to increase uptime and reliability. We claim that the pressure sensitive chair so constructed...
