Spatial and sequential tasks performed both independently and jointly were compared for 40 undergraduates grouped by sex and dominant hand. When both tasks were performed simutaneously, there was a significant advantage for right-handers and a slight advantage for males. This was attributed to hemispheric interference left-handers experienced.…

Describes a study that attempted to establish whether or not a hierarchy exists among selected reading skills, to establish the direction and strength of such a relationship, and to compare empirical methodologies for establishing hierarchical relationships. (MKM)

The age of onset for tactual exploration of the fingers, body (torso), knee, foot, and penis by the fingers was determined in 100 normal infants. Journal availability: see EC 113 765. (Author)

Describes programed classroom instruction, indicating that it should be sequenced in small steps around complete concepts to elicit responses from students and provide immediate feedback. Notes that this instructional method involves students completely but requires more preparation time and training for the teacher. A sample of programed material…

A study involving 60 blind children (in grades k-2) was conducted to validate the hypothesized order of a series of tactual discrimination tasks and to determine the grade level(s) at which most "normal blind" children successfully perform simple tactual discrimination tasks presented on the Optacon. (SBH)

Evidence is offered that children with specific language impairment often have serial memory difficulties. Research on the difficulties such children have in rote counting and in learning nursery rhymes is reviewed. Implications of current research for assessment and intervention in mathematics and rhymes are discussed. (DB)

The study compared two methods of teaching an initial place value skill: a concrete, semiconcrete, abstract teaching sequence and an abstract-only presentation. Learning-disabled elementary and middle school students (N=24) using the concrete to abstract teaching sequence performed significantly better on three posttests than students taught the…

Research suggests that cooperative learning works best when students are first taught group-processing skills, such as leadership, decision making, communication, trust building, and conflict management. Inadequate teacher training and boring assignments can torpedo cooperative learning efforts. Administrators should reassure teachers with…

Describes methods for item construction for computer-based instruction (CBI). Use of a rational set generator (RSG) in presenting an adaptive sequence of items to the learner is described; a model matrix of a computer-based RSG is presented; concrete and defined concepts are discussed; and rule using is explained. (Four references) (LRW)

Evaluates the sequential introduction of compliance training components on the instruction-following of four elementary school students. The components included effective instruction delivery with reinforcement for compliance, time in, and time out. Increased compliance levels were maintained at follow-up with all four students. Discusses results…

This article discusses the combination of skills into sequences. Combining skills into usable, challenging, and meaningful sequences is often neglected or under-used in many school and community game programs. Reasons for this under-use are discussed. Combinations of skills build on proficiency in performing separate skills and serve as…

In two H[subscript 2] [superscript 15]O PET scan experiments, we investigated the cerebral correlates of explicit and implicit knowledge in a serial reaction time (SRT) task. To do so, we used a novel application of the Process Dissociation Procedure, a behavioral paradigm that makes it possible to separately assess conscious and unconscious…

The way in which two teachers, Elizabeth and Carolyn, posed problems to develop their own conceptual understanding of division of fractions in terms that would also be meaningful for their students is described. Carolyn and Elizabeth's approach is to pose several problems of various degrees of difficulty and complexity for each aspect of the…
