Cognitive load theorists have frequently used subjective measures of cognitive load to test the effectiveness of instructional procedures. This study sought to broaden the applications of subjective measures by testing their ability to detect variations in intrinsic cognitive load within tasks. In two experiments students were asked to complete…

Studies of sentence comprehension deficits in Parkinson's disease (PD) patients suggest that language processing involves circuits connecting subcortical and cortical regions. Anatomically segregated neural circuits appear to support different cognitive and motor functions. To investigate which functions are implicated in PD comprehension…

Background: Studies focusing on reading errors can help to understand how children learn to read and to structure key components of reading instruction. However, no prior studies have examined which letters might be a greater source of difficulty for beginning readers in Spanish. Aims: First, to examine the pattern of reading errors in beginning…

A geographer and a developmental psychologist collaborated on an investigation of the development of children's ability to comprehend, produce, and use graphic representations of space. Such representations are called "geo-graphics" in this paper. The researchers held that children's mastery of maps is dependent on their developing…

Algebra word problems were analyzed in terms of the information integration tasks that are required to solve the problems. These tasks were classified into three levels: value assignment, value derivation, and equation construction. Novices (35 first year algebra students) and experts (13 analytic geometry students) were compared on the proportion…

Isolates and analyzes the errors in the English speech of a Punjabi-speaking Indian. (CK)

The study investigated whether the pre-arrangement of math facts in spaced repetitions redundancy would increase the acquisition rate of a second grader with poor mathematics achievement. Baseline data were provided by observation of in-class math performance of addition sums zero through 18. In the experimental phase, worksheet problems were…

This paper is concerned with the role of meaning and understanding in the acquisition of computational skill in subtraction. Evidence on the syntactic nature of subtraction errors is reviewed, with common "bugs" described. Then, data collected from interviews with four children are summarized in terms of their semantics of concrete…

Assessment data and other research findings on fractions are briefly reviewed. These indicate that students are able to add and subtract fractions but have substantial difficulty finding and using common denominators. Selected results for nine-year-olds from the first and second national assessments of mathematics are used to portray what students…

Spoonerisms can be elicited by having the subject articulate a target preceded by bias items. Any systematic difference in rate of errors between similar targets must result from processes after recoding of target into its slip. Editing processes make lexical outcomes more frequent than nonsense outcomes. (CHK)

The National Longitudinal Study of the High School Class of 1972 (NLS) employs a combination of mail, telephone, and personal interview data-gathering techniques. The NLS quality control process begins with editing each returned questionnaire to determine if certain key items are answered and if responses are consistent. If the respondent failed…

A research project is discussed involving the collection of production data from writing samples of 375 adult learners of English divided equally among five language backgrounds: Arabic, Chinese, Japanese, Persian, and Spanish. Information is presented about three constructions: (1) subject relative clause, (2) infinitival complement on verb, and…

During the 1975-76 academic year student response data were saved for a group of 17 freshman music majors as they worked through 15 units of harmonic dictation exercises delivered on the University of Delaware's Graded Units for Interactive Dictation Operation (GUIDO) system. Analysis of the student data base led to the identification of seven…

The paper addresses provisions for a diagnostically based remedial component for children manifesting clear and specific learning disabilities in mathematics. A model, the interactive unit, upon which a sequential program that systematically minimizes learning disabilities on mathematics performance is introduced. It is explained that the…

This report analyses justifications gathered in a series of studies which led intellectually normal infants' school and nursery school children and mildly mentally retarded special day school children to acquire conservation understanding. Two hundred and five children were given a pretest of number, mass, length, liquid, and weight conservation.…
