Describes study of elementary school students that investigated the use of computer-based pointing devices. The time required to move to a target and the type of input device are examined, the applicability of Fitts' law is discussed, and the impact of input devices on processing rate is examined.

Describes research that investigated the effectiveness of computer-based instruction (CBI) in support of mastery learning based on a study of 333 undergraduate students who used a CBI system called Management Information Systems Tutor (MIST). Student performance and time on task are examined. (Author/LRW)

Naturalistic observation techniques were used with 24 9- to 12-year-old learning disabled students to investigate two sets of variables that might influence achievement differences between computer-assisted instruction and seatwork: engagement rate and interactions with teachers and peers. Implications for research and microcomputer implementation…

Describes a study of undergraduates that compared the effects of response-certitude adaptive and nonadaptive feedback in a computer-based lesson of verbal information and defined concept tasks. Effects on student performance, feedback-study time, and lesson efficiency are discussed, and implications for future research are suggested. (LRW)

Describes a study that was designed to investigate the interaction between three levels of instructional control (i.e., linear, mixed, and learner) and provision of an orienting activity on college students' learning of factual and procedural knowledge via interactive video. Instructional time and recall of facts and procedures are examined. (35…
