Habituation and dishabituation of rats’ exploration of a novel environment

The habituation of locomotor activity across repeated exposures to a novel maze was studied in a series of experiments using rats as subjects. Habituation, defined as a decrease in ambulation, was greater on a second trial occurring 5 min after a first trial than on one occurring 60 min after. This short-term decrement occurred only when the same maze was used on both trials, and could be dishabituated by intertriai detention in another novel environment. On a delayed test trial, habituation was, in one case, somewhat greater following initial spaced trials, and in another condition, comparable following both massed and spaced trials. The longer term habituation was maze specific, but was not affected by the presence of a dishabituator following either or both of the first two trials. The results were discussed in terms of theories of “priming” and encoding variability.     

Long-range course planning by college students

A group of 633 college students at a large midwestern public university was asked fifteen questions pertaining to personal long-term course planning. The results indicated that only 48% of the students sketched out a tentative listing of at least two courses per term for one or more subsequent semesters when first planning courses for the current semester. Long-range planning was positively correlated with the number of years students had already spent in college and with students' perception of the following factors: course planning utility, degree of certainty about pursuing one's current first choice of career, and degree of commitment in using college coursework as a means of achieving a career goal (all p < 0.001). Long-range planning was negatively correlated with the anticipation of a possible change in academic interests. Such planning was not significantly correlated with students' entrance examination aptitude scores or grade point averages. Thus, students' long-range planning of courses was associated more strongly with career commitment than with recent academic performance or aptitude.     

College attrition,student use of campus facilities,and a consideration of self-reported personal problems

Five groups of undergraduate students, Dropouts (academic dismissals), Low Stopouts (voluntary leavers with low GPA), Low Persisters (continuing students with low GPA), High Stopouts (voluntary leavers with high GPA), High Persisters (continuing students with high GPA), were compared in terms of their use of various campus facilities and their responses to a checklist of personal problems. The High Stopouts and High Persisters did not differ in use of facilities. However, among the low academic performance students, the Low Persisters made significantly greater use of facilities than the Low Stopouts, who, in turn, made significantly greater use of facilities than Dropouts. These findings, for the most part, did not appear to be related to the self-reported importance of personal problems. It was concluded that among low performance students, the broad use of campus services and facilities can be taken as a measure of student integration in the college community.     

Salary comparisons: New methods for correcting old fallacies

Institutions of higher education place high priority on ensuring that their faculties are adequately paid. Since gauging the adequacy of compensation is a problem of relative measure, this assessment is usually performed by comparing university-level average salaries for a group of peer institutions. Often the potential distortions caused by differences in the rank mix of the faculty are forestalled by comparing average salaries for each of the four ranks. However, few if any institutions take similar steps to prevent the skewing of averages owing to differences in cost of living, differences in distribution of faculty in academic year and twelve-month appointments, and differences in the configuration of the faculty over disciplines. This paper shows that salary comparisons that do not compensate for these variation in staff mix are seriously flawed. A recommended methodology is demonstrated.     

Standards as a Threat to Open‐mindednes

The article examines the view that open‐mindedness, which is seen as a critical weapon in the teacher's armoury, is endangered by the movement to establish objective standards in education generally and in teacher education in particular. It analyses different ways in which standards impinge on open‐mindedness and proceeds to examine the possibilities, under each heading of the analysis, for containing the threat.     

The interdependence of language and translational math skills among bilingual hispanic engineering students

The performance of 43 Hispanic engineering and science majors on a task that consists of reading a sentence describing a mathematical relationship between two variables, and then writing an equation describing the relationship, is investigated in both English and Spanish. Results are compared with grade point average and with language proficiency. Comparison of the bilingual group to a monolingual group consisting of 52 engineering and science students shows that performance, as measured by either the mathematical translation task or grade point average, is more strongly correlated with language proficiency for the bilingual group. Clinical interviews conducted with samples from each group reveal large differences in the interpretation of the mathematical task between Hispanics and monolinguals. Suggestions are made for the improvement of the technical education of Hispanics.
