The ability to visualize student engagement and experience data provides valuable opportunities for learning support and curriculum design. With the rise of the use of learning analytics to provide "actionable intelligence" on students' learning, the challenge is to create visualizations of the data, which are clear and useful to the…

This paper lays out the rationale and implementation of student modeling and updating in the HYDRIVE intelligent tutoring system (ITS) for aircraft hydraulic systems. An epistemic level of modeling concerns the plans and goals students are using to guide their problem solving, as inferred from specific actions in specific contexts. These results…

The study evaluated the accuracy of Class.LD2, a computerized expert system for classifying learning disabled (LD) students. Of 264 student files, 78 files were chosen based on disagreement between multidisciplinary team and Class.LD2 decisions regarding eligibility for LD placement. These 78 cases were evaluated by three individuals expert in LD…

Qualitative interviews with 20 teachers of students with moderate/severe disabilities determined their use of visual analysis of graphically displayed data to evaluate the effectiveness of educational interventions. Results indicated that experienced teachers stressed student characteristics or the conditions under which the data were collected,…

The efficacy of the CATES system for making training decisions and determining student proficiency in Naval in-flight training proposed in an earlier study (Rankin and McDaniel, 1980) is compared with the present system of instructor judgments for performance assessment. The current study used 29 newly-designated naval aviators undergoing Fleet…

Project Impact, a support system for the administrative and instructional staff in the Onondaga-Madison BOCES schools, was designed to support a diagnostic-prescriptive approach in the classroom by providing the information the teacher needs in order to make instructional decisions. It consists of a series of computer programs with a large storage…

Two studies involving 27 learning-disabled middle-school students and 30 mildly handicapped junior high students investigated use of Teacher Net, a computer networking system that facilitates immediate feedback. Teacher Net reduced the teachers' administrative workload, effectively monitored student understanding, provided feedback to teachers,…

This paper suggests methods for collecting and using student information for school improvement by describing how the Richardson Independent School District (RISD), Texas, determines data for effective school management decisionmaking. RISD readily accesses student information via a networked database on line with the central office's IBM…

As part of a project formulating optimal rules for decision making in computer assisted instructional systems in which the computer is used as a decision support tool, an approach that simultaneously optimizes classification of students into two treatments, each followed by a mastery decision, is presented using the framework of Bayesian decision…

The research project investigated whether expert system tools have become sophisticated enough to be applied efficiently to problems in special education. (Expert systems are a development of artificial intelligence that combines the computer's capacity for storing specialized knowledge with a general set of rules intended to replicate the…
