Explorations in policy enactment: feminist thought experiments with Basil Bernstein’s code theory

This paper builds on feminist elaborations of Bernstein’s code theory to engage in a series of thought experiments with interview data produced during a co-inquiry design-based research intervention project. It presents three accounts of thinking/writing with data. Our purpose in presenting three different accounts of interview data is to demonstrate the relation between theory and empirical data. In the first two accounts, interview data are interpreted and performed through the lens of theory. By contrast, in the third account attention is paid to the ways in which care is practised not only in terms of policy enactment, but also research enactment. Empirical data are not moulded to fit generalisable theoretical frameworks. Rather, empirical data push back on theoretical concepts in a collaborative thought experiment.     

Comparison of Methods for Combining the Minimum Passing Levels for Individual Items into a Passing Score for a Test

The purpose of this study was to compare several methods for determining a passing score on an examination from the individual raters' estimates of minimal pass levels for the items. The methods investigated differ in the weighting that the estimates for each item receive in the aggregation process. An IRT-based simulation method was used to model a variety of error components of minimum pass levels. The results indicate little difference in estimated passing scores across the three methods. Less error was present when the ability level of the minimally competent candidates matched the expected difficulty level of the test. No meaningful improvement in passing score estimation was achieved for a 50-item test as opposed to a 25-item test; however, the RMSE values for estimates with 10 raters were smaller than those for 5 raters. The results suggest that the simplest method for aggregating minimum pass levels across the items in a test–adding them up–is the preferred method.     

Object Properties and Knowledge in Early Lexical Learning

The ease with which young children learn object nouns suggests that they possess strategies to identify properties critical to lexical category membership. In previous work, young children used a same-shape criterion to extend new count nouns. The present research tested the generality of this shape bias. 2- and 3-year-olds were asked either to extend a novel count noun to new instances, or to choose unnamed objects to go together. The objects varied in shape, size, and texture. For half of the subjects, the objects had eyes--a property strongly associated with certain material kinds. If young children know this association, they should attend to texture as well as shape in classifying objects with eyes. With named objects only, both 2- and 3-year-old children classified eyeless objects by shape and objects with eyes by both shape and texture. The results suggest that very young children possess considerable knowledge about conditional relations between kinds of perceptual properties. Knowledge of such conditional relations may aid children in forming new categories and thus in discovering new word meanings.

Gender, ‘bias’, assessment and feedback: analyzing the written assessment of undergraduate history essays

This paper reports on findings relating to a project on gender and essay assessment in HE. It focuses on one aspect of the study: the assessment of and feedback given to two sample essays by 50 historians based at universities in England and Wales. We found considerable variation both as to the classification awarded to the essays and to positive and negative comments made about their quality, supporting the argument that the ‘quality’ of a piece of writing for assessment is ultimately constructed by the reader of the essay and cannot be objectively ascertained. Gender issues emerging from the data are explored in the paper, relating to lecturers’ perceptions of the essays’ qualities; views concerning the way feedback should be presented; and the content and style of feedback given by lecturers on the sample essays. We found that gender constructions were manifested more in presentation than practice. These findings on the situated practice of assessment have implications for the conception of the ‘reliability’ of essay assessment in HE.     

The decline of academic motivation during adolescence: an accelerated longitudinal cohort analysis on the effect of psychological need satisfaction

Adolescents typically exhibit a marked decline in academic intrinsic motivation throughout their school careers. Following self-determination theory, it is hypothesised that traditional school environments insufficiently satisfy three basic psychological needs of youths during maturation, namely the needs for autonomy, competence and relatedness. As a consequence, insufficient need satisfaction might account for the decline in intrinsic academic motivation during adolescence. This hypothesis was tested in an accelerated longitudinal cohort design on N = 600 students (286 girls) between 11 and 16 years of age. The results showed that students exhibited a marked decline in intrinsic motivation during adolescence. Moreover, differences in need satisfaction predicted the decline in motivations. These results support the notion that an adequate satisfaction of three basic psychological needs in school is crucial for the maintenance of intrinsic academic motivation during adolescence.     

Estimation performance and strategy use of Mexican 5th and 8th grade student sample

What computational estimation skills and strategies do Mexican students possess? Does the theoretical model based on interviews with a select United States sample accurately describe the Mexican sample? These were questions studied based on interviews with 8 eighth graders (those scoring in the top 5%) out of a sample of 177 eighth graders from twelve different Mexican schools representing a range of social and economic backgrounds. Preliminary screening data collected by administering a computational estimation test revealed that estimation was very difficult for the Mexican students (mean 4.0, range of 0 to 18 on the 38-item open-ended test). The interviews revealed that the Mexican students as a whole did employ the three general cognitive processes outlined in the theoretical model, namely reformulation, translation, and compensation. The most common strategy employed was the front-end technique. Similarly, a frequent strategy used to “estimate” was mentally applying a paper/pencil algorithm. In contrast to data collected under similar conditions in Japan and the United States, rounding was a strategy only occasionally used in the interviews. The use of benchmarks (key reference points used as bounds in forming an estimate) as a strategy for estimating problems involving percent was common and may reflect students' “out-of-school” experience with mathematical applications. Consistent with parallel investigations with Japanese and United States students, these Mexican strudents rarely reflected on their estimates through their own initiative and rarely recognized unreasonable estimates.     

Who succeeds? II. Perceptions of graduates and inactive students of a nontraditional bachelor of arts degree program

A questionnaire was returned by 241 (79%) graduates and 75 (31%) of the inactive students of a nontraditional BA degree program. A profile of each type of adult learner was presented and differences between the profiles in age and ethnic affiliation are discussed. The two groups did not differ in primary reason for seeking a degree or a nontraditional program, but graduates gave more reasons in each case. Graduates were more likely to perceive dispositional, communication, and program variables as assets. Inactive students were more likely to perceive time to study and cost of courses as problems. Results are compared to the concept of educational barriers.Dr. Losty is Associate Dean of the Faculty at Stephens College, Columbia, Missouri.
