intelligent tutoring system

Examples of Intelligent Tutoring Systems in Education
Algebra Tutor PAT (PUMP Algebra Tutor or Practical Algebra Tutor) developed by the Pittsburgh Advanced Cognitive Tutor Center at Carnegie Mellon University, engages students in anchored learning problems and uses modern algebraic tools activate students to problem solve and share results. The aim of PAT is to able to tap into a students prior knowledge and their day to day experiences with mathematics in order to promote growth. The success of PAT is well documented (exp. Miami-Dade County Public Schools Office of Evaluation and Research) from both a statistical (student results) and emotional (student and instructor feedback) perspective.

Mathematics Tutor The Mathematics Tutor (Beal, Beck & Woolf, 1998) helps students solve word problems using fractions, decimals and percentages.The tutor records the success rates when student is working on the problems and subsequent problems that are predicted to fit student’s level will be selected and an estimated desirable time will be given to the student to solve the problem[18].
eTeacher eTeacher (Schiaffino et al., 2008) is an intelligent agent that supports personalized e-learning assistance. It builds student’s profile while observing student performing in online courses. Then eTeacher uses the information from student’s profile to suggest their personalized courses of action that assist their learning process[19].
ZOSMAT ZOSMAT was designed to address all the needs in a real classroom. It follows and guides a student in different stages of their learning process. This is a student-centered ITS that records the progress in student’s learning progress depends on their effort. ZOSMAT can be used for either individual learning or real classroom environment with the guidance of a human tutor[20].
REALP REALP was designed to help students enhance reading comprehension by providing reader-specific lexical practice and offering personalized practice in useful, authentic reading materials gathered from the Web. The system automatically build a user model according to student’s performance. After reading, the student will be given a series of exercises based on the target vocabulary found in reading[21].
CIRCSlM-Tutor CIRCSIM_Tutor is an intelligent tutoring system that is used with first year medical students at the Illinois Institute of Technology. It uses natural dialogue based, Socratic language to help students learn about regulating blood pressure.
Why2-Atlas Why2-Atlas is an ITS that analyses students explanations of physics principles. The students input their work in paragraph form and the program converts them into a proof by making assumptions of student beliefs based on their explanations. In doing, misconceptions and incomplete explanations are highlighted. The system then addresses these issues through a dialogue with the student and asks the student to correct their essay. A number of iterations may take place before the process is complete.

SmartTutor The University of Hong Kong (HKU) developed a SmartTutor, to support the needs of continuing education students. Personalized learning was identified as a key need within adult education at HKU and SmartTutor aims to fill that need. SmartTutor provides support for student by combining Internet technology, educational research and artificial intelligence[22].
AutoTutor Auto Tutor assists college students in learning hardware, operating systems and Internet in an introductory computer literacy course by simulating the discourse patterns and pedagogical strategies of a human tutor. Auto Tutor attempts to understand learner’s input from keyboard and formulate dialog moves with feedback, prompts, correction and hints[23].
ActiveMath ActiveMath is a web-based, adaptive learning environment for mathematics. These systems strive for improving long-distance learning, for complementing traditional classroom teaching, and for supporting individual and life-long learning[24].

[edit] Examples of Intelligent Tutoring Systems in Corporate Training and Organizational Learning

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[25].
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 and feedback in order to personalize and optimize the learning. Each simulation, regardless of whether the students were successful able to help their patients, results in a detailed report which students review[26].
