Generalized Intelligent Framework for Tutoring (GIFT)
Description | Background | Research Goals | Obtaining GIFT Software | Features | GIFT Documents | Releases
GIFT is an empirically-based, service-oriented framework of tools, methods and standards to make it easier to author computer-based tutoring systems (CBTS), manage instruction and assess the effect of CBTS, components and methodologies. GIFT is being developed under the Adaptive Tutoring Research Science & Technology project at the Learning in Intelligent Tutoring Environments (LITE) Laboratory, part of the U.S. Army Research Laboratory - Human Research and Engineering Directorate (ARL-HRED).
The technology gap for a reusable CBTS framework to support individual and small team tutoring was identified through a review of the intelligent tutoring systems (ITS) literature in 2009-2010 and the Training and Doctrine Command (TRADOC) formalized the Army requirement for GIFT in their Army Learning Concept (2011). GIFT was brought to practice in 2011 by the LITE Lab team. The first public demonstration of GIFT was conducted at the Interservice/Industry Training Systems and Education Conference (I/ITSEC) in December 2011. The first release of GIFT was completed in May 2012.
While GIFT is being developed to facilitate the use of CBTS by the U.S. Army, the intent is to collaboratively develop GIFT and have it function as a “nexus” for CBTS research being conducted within government, industry and academia.
Research Goals Adaptive Tutoring research goals that are driving future GIFT development include:
an ontology to represent the knowledge and concepts of CBTS, their relationships and their interactions
automated tools and processes to author CBTS, their models, and components
automated delivery methods for tailored instruction to individuals and small teams
a set of reusable, domain-independent modules that include standard processes and structures
a testbed methodology to support the systematic comparison and assessment of CBTS, their components, and instructional methods
Obtaining GIFT Software
After registering on this site, the GIFT software, including source code, is available for download on the Downloads tab
GIFT consists of several core modules which interact with each other to perform the functions within a Computer-Based Tutoring System (CBTS). The Sensor Module has interfaces to support commercial sensors (e.g., Affectiva Q-Sensor) and its function is to format, process and store sensor data. The Domain Module provides domain content to support training, assesses trainee performance against standards, and provides domain-specific feedback to the trainee when the Pedagogical Module identifies the need for feedback based on trainee performance. The Trainee Module uses trainee performance, historical data (e.g., past performance) and sensor data to determine the trainee’s cognitive and affective state.
Each of these Modules is interchangeable through the virtue of interfacing standards. This allows each Module designer to select the type of approach that they believe is suited towards instruction. For instance, a sample configuration may have a webcam sensor that interprets Facial Action Units (FACs), a rule-based performance assessment, a Feedback Generation Engine that generates varying levels of hints upon request, a finite state machine of trainee assessment, and pedagogy that gives hints on failed problems.
This release features functional elements of each of the modules in a game-based tutoring domain. It does this on top of the training content created by the Games for Training (http://www.peostri.army.mil/PRODUCTS/USAGFTP/).
Sensor Module - includes the Affectiva Q sensor to measure electrodermal activity (EDA); a custom mouse sensor to measure EDA; and a software-based "Self Assessment" sensor that can be manipulated for testing
Learner Module - functions as a prototype pass-through module, collating information from VBS2 and the respective sensors
Pedagogical Module - acts to give hints on concepts which are 'underperforming'
Domain Module - listens to VBS2 traffic, assesses performance on 4 different tasks, supports varying levels of feedback as requested
In addition to functional Modules, several additional components are included for researchers, including:
The ability to author your research questions with the Survey Authoring Tool
The functionality to keep track of users and historical performance inside of a mySQL database
The ability to analyze sensor/performance/assessed data after an experiment in a collated .csv file, with your choice of software
A longer description of the current project and goals is available under the Documents Tab. This paper is the recommended paper for citation.
If you are looking to develop with GIFT, we recommend the "Unwrapping GIFT" series of documents, found here (http://ceur-ws.org/Vol-1009/0702.pdf) and in the GIFTSym proceedings each year.
The software documentation for GIFT is extensive, updated, and complete. It is available with each GIFT download, in the Downloads section.
Other information such as answers to the "I'm wondering where to get started...?" and "How can I automatically conduct an experiment with GIFT?" questions can be found in the GIFT Forums (https://gifttutoring.org/boards/6/topics/205) and (https://gifttutoring.org/boards/6/topics/342), respectively.

Corporate training and industry
Generalized Intelligent Framework for Tutoring (GIFT) is an educational software designed for creation of computer-based tutoring systems. Developed by the U.S. Army Research Laboratory from 2009 to 2011, GIFT was released for commercial use in May 2012. GIFT is open-source and domain independent, and can be downloaded online for free. The software allows an instructor to design a tutoring program that can cover various disciplines through adjustments to existing courses. It includes coursework tools intended for use by researchers, instructional designers, instructors, and students. GIFT is compatible with other teaching materials, such as PowerPoint presentations, which can be integrated into the program.
SHERLOCK "SHERLOCK" is used to train Air Force technicians to diagnose problems in the electrical systems of F-15 jets. The ITS creates faulty schematic diagrams of systems for the trainee to locate and diagnose. The ITS provides diagnostic readings allowing the trainee to decide whether the fault lies in the circuit being tested or if it lies elsewhere in the system. Feedback and guidance are provided by the system and help is available if requested.
Cardiac Tutor The Cardiac Tutor's aim is to support advanced cardiac support techniques to medical personnel. The tutor presents cardiac problems and, using a variety of steps, students must select various interventions. Cardiac Tutor provides clues, verbal advice, and feedback in order to personalize and optimize the learning. Each simulation, regardless of whether the students were successfully able to help their patients, results in a detailed report which students then review.
CODES Cooperative Music Prototype Design is a Web-based environment for cooperative music prototyping. It was designed to support users, especially those who are not specialists in music, in creating musical pieces in a prototyping manner. The musical examples (prototypes) can be repeatedly tested, played and modified. One of the main aspects of CODES is interaction and cooperation between the music creators and their partners.more » « less
