This paper proposes a computer-aided teaching model using knowledge graph construction and learning path recommendation. It first creates a multimodal knowledge graph to illustrate complex relationships among knowledge. Learning elements and sequences are then used to form time sequences stored as directed graphs, supporting flexible path…

In building intelligent tutoring systems, it is critical to be able to understand and diagnose student responses in interactive problem solving. However, building this understanding into a computer-based intelligent tutor is a time-intensive process usually conducted by subject experts. Much of this time is spent in building production rules that…

As course management systems (CMS) gain popularity in facilitating teaching. A forum is a key component to facilitate the interactions among students and teachers. Content analysis is the most popular way to study a discussion forum. But content analysis is a human labor intensity process; for example, the coding process relies heavily on manual…

Surveys some of the benefits claimed for data-logging methods identified through research. Discusses findings from research that sought to explore the translation of these benefits into the real-world of science classrooms and identify the range of influences on science teachers adopting and developing data-logging methods.

Presents a detailed analysis of courseware design activities based upon the use of conceptual data models for content elaboration. Highlights include discussions of computerized training systems, authoring languages and authoring systems, and the distinction between processing and data. (Author/LRW)

This paper presents a study on the effects of various data compression methods from the viewpoint of central computer to terminal communications on a large graphics oriented timesharing system, PLATO IV. The desired goal is to increase terminal display speed without significant increase in the transmission error rates. While the major emphasis in…

VOCAL (Voice Oriented Curriculum Author Language) is designed to facilitate the authoring of computer assisted curricula which incorporate highly interactive audio and text presentations. Lessons written in VOCAL are intended to be patterned after the style of informal classroom lectures. VOCAL contains features that allow the author to specify…

Discusses issues faced by the Federal Aviation Administration (FAA) when designing large computer based training systems (CBTs), and offers a conceptual model for interpreting CBT issues. (MER)

In 1974, as part of a reciprocal agreement between Canada and the Federal Republic of Germany, a delegation of Canadian experts visited Germany to examine programs in Computer Assisted Instruction (CAI) and to explore areas of future cooperation. The delegation examined CAI program support and administrative structures in German education. Special…

Difficulties in implementing the EXCHECK/VOCAL System, a general program for mathematics instruction written in the VOCAL language, are presented in terms of informal mathematics procedures, audio and prosodic features, and proposed research. References are appended. (CMV)

A survey of the 28 Florida community colleges was conducted to determine the type and amount of computer hardware and software used at each college and to obtain colleges' evaluation of their own administrative software. Responses from 27 colleges revealed that: (1) of the 26 colleges with administrative data processing systems, 13 had IBM systems…

To determine the number and current use of microcomputers in Alberta's elementary, junior, and senior high schools, a total of 1,509 schools were surveyed. The results, as reported by 1,271 schools (84.2%), showed the total number of microcomputers to be 13,748. To provide more in-depth information, schools were categorized by six instructional…

This study explores a wide variety of technical alternatives, from equipment needs and on-the-ground system design, to equipment operation and suggested applications for department activities, both now and in the future. Some suggested alternatives include (1) communication satellites, (2) one way audio transmission, (3) one and two way hard copy…

This report describes a computer managed instruction (CMI) system operated by the Navy which involves approximately 9,000 students a day in ten technical training schools, and the research and development effort that has taken place to ensure the most cost-effective and productive technical training system. Major system problems were identified…

To minimize training time, an adaptive training model for optimizing path sequencing in computer aided instruction was developed. The model reduced a course to logical components or quanta, then plotted the material for possible sequences and evaluated each component quanta as to importance to subject assimilation. For implementation and testing,…
