Considers a class of estimation procedures for the factor model. The procedures are shown to yield estimates possessing the same asymptotic sampling properties as those from estimation by maximum likelihood or generalized last squares, both special members of the class. General expressions for the derivatives needed for Newton-Raphson…

Discusses the idea that with larger cohorts of the very old, subjects in their 80s and 90s will be increasingly sought as respondents. Points out various steps that need to be taken to assure that this older group will be represented by the ailing as well as the healthy community residents. (Author/EJT)

This study investigated school innovativeness and a number of variables commonly found to be associated with this phenomenon in similar North American studies. (Editor)

The relation in schoolchildren of duty and efficacy to trust is the principal topic of this study. (Author/RK)

Authors attempted to measure a few key variables associated with the Porter-Lawler (1968) expectancy model in order to determine its validity. (Author/RK)

Article examined the validity of some of Piaget's and Bruner's findings in non-western cultures, the relationship between cognitive models that they developed, and the implications for curriculum, teaching and learning of any data newly discovered. (Author/RK)

Considered the advantages of knowing how parents feel about the secondary school curriculum. (RK)

A total of 484 tenth-grade students, evenly divided between schools with Commonwealth libraries and those without, were assessed for motivational dispositions (need for achievement, test anxiety, and sense of responsibility for successes and failures), academic values, and displayed motivation (as revealed in choice of tasks).

This literature review addresses the technical adequacy of time sampling observation systems, which is fundamental to ensuring the generalizability of data obtained from behavioral observation. Investigations comparing partial interval, whole interval, and momentary time sampling have yielded consistent results. These suggest that duration of…

This paper explains the methodology and procedures used by the Center for the Study of Community Colleges (CSCC) in carrying out a national survey of community college students to gather information on student demographic characteristics, educational background, educational objectives, and opinions about the college experience. As background…

Most of the observational study of marriage has focused on relatively young and highly educated couples from professional backgrounds; working-class couples, older couples, and couples from distressed marriages seem reluctant to volunteer for research on close relationships. The development of techniques for recruiting these couples represents an…

This simple method for simulating the Central Limit Theorem with students in a beginning nonmajor statistics class requires students to use dice to simulate drawing samples from a discrete uniform distribution. On a chalkboard, the distribution of sample means is superimposed on a graph of the discrete uniform distribution to provide visual…

After the terms "qualitative research" and "quantitative research" are defined, this paper considers why it makes sense to integrate these approaches, at least under some circumstances. This discussion necessitates attention to the issue of whether quantitative and qualitative research are inextricably linked to incompatible…

Present research connected with computer-based instruction indicates that many investigators rely on conventional experimental design and data analysis to address the research question. Although this is appropriate in many cases, the limits of hard and software resources and sample size in other cases have made conventional approaches a poor…
