A principal limitation of frame-based computer assisted instruction (CAI) results not from the characteristics of the computer medium, but rather from prior instructional design practices, specifically the logical abstraction of behavioral objectives. Learning hierarchy-based instruction implemented in the interactive computer-based medium results…

Levels of independent variable(s) are often mixed within each block of trials rather than each level being presented in a separate block in research of various types. Two experiments involving tasks of a visual nature were conducted to demonstrate that such mixing can easily obscure the effects of principal interest. A target circle was projected…

Data for this analysis of classroom instruction were part of the junior high phase of the Managing Academic Tasks (MAT) study (Doyle, Sanford, Clements, French & Emmer, 1983). The MAT focuses on the character of academic tasks, the nature of the overall task systems that operate in classrooms, and the contexts associated with task…

Discusses many factors involved in determining the complex nature of a child's knowledge base. Includes three kinds of considerations: 1) task-oriented criteria; 2) motivational elements; and 3) the relationship between personality and performance. (Author/CS)

The author evaluates three remedial approaches to learning disabled (LD) children as defined by B. Batemen: the etiological approach which focuses on causation; the diagnostic remedial approach which focuses on behavioral manifestations of LD; and the task analytic approach which emphasizes the task and teaching methods rather than learner…

The development of a large body of e-­learning specifications, such as IMS and SCORM, has led to the proposal for a new way to facilitate content workflow. This involves the movement of educational digital content and the knowledge of pedagogical communities into an online space. Several projects have looked at the theoretical structure of these…

Methods for examining the processes being utilized in meetings and evaluating them to increase the effectiveness of organizations are described. (AJ)

It is hypothesized and found that organizational positions systematically vary in their replacement rates. This variation is directly associated with positional visibility; visibility is also found to relate to salaries and the racial composition of positional occupants. (Author/AJ)

A project was undertaken to devise an improved method for determining the workload generated by each direct instructional, instructional-related, and professional-related activity carried out at Colorado State University and the estimated workload expected of each instructional faculty member. These load factors specifically recognize the input…

Sinclair-de Zwart's findings on relationships between cognitive and linguistic development were compared with data gathered in Australia from 162 first-, second-, and third-grade Greek-English bilinguals (tested in both languages) and 136 English monoglots in the same classroom. (Author/CS)

Subjects of several ages were asked to copy, trace, or point to the beginning of a set of shapes. The aim was to determine the extent to which sequential behavior was consistent across tasks. With one notable exception, behavior was consistent. (Author/BJG)

Revision of paper presented at California Teacher's Association Staff Conference on Problem Solving (Asilomar, California, January 30, 1968).

The Job Characteristics Model proposed by Hackman and his associates postulates that positive personal and work outcomes are derived from five core job dimensions: skill variety, task identity, task significance, autonomy, and feedback from the job. The effects of the number of workers (work group size) and the number of tasks (task size) on…
