Summary of a conceptual model of service quality and its implications for future research

Universities Among the earliest systematic analyses of college outcomes are those of C. Focusing on both longitudinal changes and cross-sectional differences, this body of research generated some of the first significant impressions of the efficacy of college attendance. By and large, these studies explored basic distinctions between those who attended college and those who did not.

As is seen, it is also possible to depict all one-step multiplication and division problems using the same format. Vergnaud identified two different types of relationships in the entries of this diagram: In both situations the relationships are multiplicative in nature: Using the scalar within measure space relationship from this table, a-c implies a multiplication by or a is mapped onto c by the multiplicative operator In proportional situations, b-x implies the same multiplicative relationship and we have: Therefore c-x implies the same relationship and we have: Because the quantities are proportional, the same relationship exists between b and x.

Similarly, in Equation 2the functional relationship between a and b is defined as b over a. By stressing early the multiplicative relationships between any two numbers, children can be taught to extend their understandings and apply them directly to a rich class of problem situations in a more meaningful manner than is currently being done.

These implicit models are very resistant to change and cause difficulties later on. It is likely that the general phenomenon of stressing interrelations within and between mathematical domains will replicate itself many times over as new insights are gained into both the mathematical as well as the pedagogical aspects of the topics embedded in school mathematics curricula.

Underlying each of these advances has been the use of research paradigms different from those in vogue 20 or more years ago. There has been much research with individuals or with small groups of students, utilizing extensive observation and participation, regular in-depth student interviews, and protocol analyses.

The teaching experiment, and other ethnographically oriented paradigms, have been the paradigms of choice for many mathematics educators during the past 15 years.

Protocols resulting from student interviews, many of which have resulted from teaching experiments, have provided rather detailed insights into the ways in which students come to know a mathematical concept. Such information was largely unavailable in the s and s, given the experimental paradigms then in use.

More sophisticated information is now available. Our own work has utilized the teaching experiment on four different occasions since Instructional periods consisted of 121830and 17 weeks respectively.

The first three dealt with a variety of rational number subconcepts part-whole, decimal, ratio, and measure -the last related to the role of rational number concepts in the evolution of proportional reasoning skills at the seventh-grade level.

In general, project personnel would assume responsibility for all rational number-related instruction 4 days per week. Respectively, 6, 9, 30, and 9 students participated in the experiments. All students were interviewed regularly in the smaller classes and a selected group of eight or nine students were interviewed in the third experiment, which utilized a whole-class situation for instructional purposes.College and its Effect on Students - Early Work on the Impact of College, Nine Generalizations, Later Studies, Pascarella and Terenzini.

The process of developing this conceptual framework brought out a number of significant realizations: that the intellectual effectiveness exercised today by a given human has little likelihood of being intelligence limited—that there are dozens of disciplines in engineering, mathematics, and the social, life, and physical sciences that can contribute .
