Curriculum tracking and teacher evaluations of individual students: selection, adjustment or labeling?

Past research into the consequences of tracking mainly documented on the impact of attending different tracks on students’ achievement and behavior. Less attention has been paid to the impact of track positions on teachers’ perceptions and expectations regarding students. By means of multi-level analysis of data of 6,545 students in 46 Flemish secondary schools with self-reported student measures and teachers’ evaluations of students, this study examines if teachers’ evaluations of secondary school students’ cognitive capacity, effort in class and diligence in doing homework vary by track, and whether teachers’ perceptions are informed (1) by the typical students’ background features; (2) by the students’ resistance to school; or (3) by labeling of students attending certain tracks. Teachers perceive lower track students as less able and less diligent in doing homework because of students’ social and cognitive characteristics and anti-school behavior. Accounting for the latter, teachers even evaluate lower track students as paying slightly more effort. The implications for future research and social policy are discussed.     

Mixed methods research design for pragmatic psychoanalytic studies

Calls for more rigorous psychoanalytic studies have increased over the past decade. The field has been divided by those who assert that psychoanalysis is properly a hermeneutic endeavor and those who see it as a science. A comparable debate is found in research methodology, where qualitative and quantitative methods have often been seen as occupying orthogonal positions. Recently, Mixed Methods Research (MMR) has emerged as a viable "third community" of research, pursuing a pragmatic approach to research endeavors through integrating qualitative and quantitative procedures in a single study design. Mixed Methods Research designs and the terminology associated with this emerging approach are explained, after which the methodology is explored as a potential integrative approach to a psychoanalytic human science. Both qualitative and quantitative research methods are reviewed, as well as how they may be used in Mixed Methods Research to study complex human phenomena.     

Questionnaire of executive function for dancers: an ecological approach

There is a current debate about the ecological validity of executive function (EF) tests. Consistent with the verisimilitude approach, this research proposes the ballet executive scale (BES), a self-rating questionnaire that assimilates idiosyncratic executive behaviors of classical dance community. The BES was administrated to 149 adolescents, students of the Cuban Ballet School. Results present a Cronbach's alpha coefficient of .80 and a split-half Spearman-Brown coefficient r (SB) = .81. An exploratory factor analysis describes a bifactorial pattern of EF dimensions, with a self-regulation component, which explains more than 40% of variance, and a Developmental component, which accounts for more than 20% of variance. The questionnaire's total scores fit linear regression models with two external criteria of academic records, confirming concurrent validity. These findings support the hypothesis that the internalization of specific contextual cultural meanings has a mediating influence in the development of EF.     

TEACHING MEMORIZED SPELLING WITH A MICROCOMPUTER: TIME DELAY AND COMPUTER-ASSISTED INSTRUCTION

A computer-assisted instruction program was evaluated that used a constant time-delay procedure to teach 5 students 18 spelling words. In addition to delivering the instructional procedure, the program managed the presentation of training content based on individual student responding and collected instructional data on individual student performance. The procedure was effective at teaching 4 of the 5 students the words, and generalization occurred from the computer-delivered keyboard response format to a teacher-delivered hand-written response format. Maintenance data varied among the students. The study demonstrated the feasibility of using microcomputers to deliver time-delay instruction in special education classrooms and suggested several research questions related to specific features of microcomputer-delivered time-delay instruction.     

Variability of olfactory threshold and its role in assessment of aging

Olfactory thresholds of elderly persons (over 65 years) average one to two orders of magnitude higher than those of young adults (under 30 years). Past studies reveal enormous spreads (typically about three orders of magnitude) of individual thresholds within each age group and extensive overlap between the two groups—enough to question how typically decline in sensitivity characterizes the individual aged person. The present study shows that much of the observed overlap is misleading, because the brief threshold tests usually administered tend to exaggerate individual differences. A more representative assessment of an individual’s threshold (for 1-butanol) was achieved by averaging the thresholds from two to eight separate short tests, spread over 4 days. The spread of each group’s thresholds (12 young and 12 elderly subjects) narrowed strikingly as the number of tests averaged increased from one to four; further tests accomplished no additional narrowing of spread. Based on a single test, thresholds of young and elderly overlapped in the usual way; but based on four or more tests, thresholds of young and elderly overlapped little or not at all. The outcome (1) argues that decline in smell sensitivity seems to be, after all, a common feature of aging, and (2) sheds light on the sourcesof variability of sensory thresholds.
