Word reading fluency: A transfer appropriate processing account of fluency transfer

Word reading fluency, as indexed by the fast and accurate identification of single words, predicts both general reading ability and reading comprehension. This study compared the effects of context training and isolated word training on subsequent measures of word reading fluency. Good and poor readers were given 12 repetitions of two sets of words; 48 new words were learned in each condition. Words were presented in a story during context training and on a computer screen during isolated word training. Target words were read in isolation at test, randomly displayed within a series containing 72 untrained words. Results show that words trained in isolation are remembered longer and read faster when presented in isolation at test compared to words trained in context. Theoretical implications are discussed in relation to transfer appropriate processing.     

Unraveling sources of stimulus control in a temporal discrimination task

In temporal discriminations tasks, more than one stimulus may function as a time marker. We studied two of them in a matching-to-sample task, the sample keylight and the houselight that signaled the intertrial interval (ITI). One group of pigeons learned a symmetrical matching-to-sample task with two samples (2 s or 18 s of a center keylight) and two comparisons (red and green side keys), whereas another group of pigeons learned an asymmetrical matching-to-sample task with three samples (2 s, 6 s, and 18 s) and two comparisons (red and green). In the asymmetrical task, 6-s and 18-s samples shared the same comparison. In a subsequent retention test, both groups showed a preference for the comparison associated with the longer samples, a result consistent with the hypothesis that pigeons based their choices on the duration elapsed since the offset of the houselight (i.e., sample duration + retention interval). Results from two no-sample tests further corroborated the importance of the ITI illumination as a time marker: When the ITI was illuminated, the proportion of choices correlated positively with the retention interval; when the ITI was darkened, choices fell to random levels. However, the absolute value of choice proportions suggested that the sample stimulus was also a time marker. How multiple stimuli acquire control over behavior and how they combine remains to be worked out.     

Are the Notion of Mean and Related Concepts too Difficult for 6th and 7th Grade Biology Students?

Basic statistical concepts are considered to be part and parcel of any modern biological education. Micro‐computer assisted activities may offer new opportunities for the early development of relatively young children's skills and understandings, thus preparing them efficiently for a meaningful secondary school science education. However, the relevant skills and concepts may well be beyond the ken of such children. In this study, we attempted to check the level which could be reached with 6th and 7th grades primary school students (11‐12 years of age), concerning the connected concepts of “mean” and “deviation” from the mean, and some major implications of these concepts. Special learning activities were developed, and an electronic spreadsheet was used as the main tool for the quantitative tasks. A one year period of intensive teacher training preceded the actual experiment. The main results will be delineated, as well as the main responses of the students and of the teachers. Although the schools selected for the experiment (experimental as well as control groups) were located in areas of a relatively high socio‐economic level, there was some heterogeneity in the classes. The results will show that educators are confronted with problems of heterogeneity even in “good” classes, and that finding the appropriate level of intellectual stimulation of different pupils is not an easy task. Some concepts appeared to be at the limit of, or beyond, the abilities of many students, but by no means of all of them.     

Universities as a meeting point with new academic knowledge,society and culture: cognitive and emotional transitions during higher education

This paper examines how exposure to a different culture, acquired knowledge and everyday practices at Israeli universities affected the identities of the ‘First Women’ students from the Druze minority who broke gender roles and turned to acquire higher education. The short distance between the Druze villages and the university required a longer and far more complex journey than the women imagined when they decided to study. The paper analyses ways in which the university atmosphere imparts values, norms, knowledge and practices that enable individuals to reassess their identities. Thirty‐four interviews with Druze women, who were the first in their community or their respective villages to obtain higher education, were analysed, allowing a study of the different experiences and various paths of change and their intricate effects on framing identity.     

Adolescent social competence: effectiveness in a group setting

We used a longitudinal data set to evaluate an observational assessment of adolescent competence within a group context. Participants were 40 (21 males, 19 females) ethnically diverse children who had earlier been observed in summer camp (age 10) and preschool (age 4 1/2), as well as in infancy. A revealed differences task was videotaped as part of an intensive weekend camp reunion at ages 15 to 16. Raters, blind to the adolescents' developmental histories, coded each adolescent on the following behavioral rating scales: enjoyment of the task, involvement, leadership, self-confidence in the task, and global social competence. Both concurrent validity (strong correlations with independent camp reunion counselor ratings and peer sociometric measures) and clear associations with antecedent measures of peer competence in preschool and middle childhood were demonstrated. A pattern of correlations revealed considerable discriminate validity. Neither IQ nor socioeconomic status accounted for these associations. Overall, the results confirm the power of a developmentally appropriate, taxing, behaviorally based assessment of group functioning as a measure of competence in adolescence.     

Continuing education as a catalyst for inter-professional collaboration

Do nurses have access to the tools and resources they need for evidence-based practice? Are librarians prepared to work with nurses to provide access to appropriate resources and services, and teach the needed information literacy skills? The authors work with professional library and nursing organizations to present interdisciplinary continuing education to improve the information literacy of nurses and the ability of librarians to provide resources and services that meet nurses' information needs. This article reviews behavioral and practice changes reported by nurses and librarian participants in symposia on evidence-based nursing in March 2001 and May 2003.     

Aspiration levels and educational choices: An experimental study

The explanation of social inequalities in education is still a debated issue in economics. Recent empirical studies tend to downplay the potential role of credit constraint. This article tests a different potential explanation of social inequalities in education, specifically that social differences in aspiration level result in different educational choices. Having existed for a long time in the sociology of education, this explanation can be justified if aspiration levels are seen as reference points in a prospect theory framework. In order to test this explanation, this article applies the method of experimental economics to the issue of education choice and behaviour. One hundred and twenty-nine individuals participated in an experiment in which they had to perform a task over 15 stages grouped in three blocks or levels. In order to continue through the experiment, a minimum level of success was required at the end of each level. Rewards were dependent on the final level successfully reached. At the end of each level, participants could either choose to stop and take their reward or to pay a cost to continue further in order to possibly receive higher rewards. To test the impact of aspiration levels, outcomes were either presented as gains or losses relative to an initial sum. In accordance with the theoretical predictions, participants in the loss framing group choose to go further in the experiment. There was also a significant and interesting gender effect in the loss framing treatment, such that males performed better and reached higher levels.     

Multilateral agencies and higher education reform in Latin America

During the last decade, the debate over higher education took up a significant space on the agendas of various international agencies, including multilateral development banks and other intergovernmental agencies. This fact points to the importance of the subject within a broader discussion that refers to national development projects and their articulation within the new international economic and political order. In this context, the purpose of this article is to discern the principal lines of argument at work and their implications for the transformation of higher education in Latin America. To this end, we have chosen four cases that we consider relevant for the region: The United Nations Education, Science and Cultural Organization (UNESCO), the World Bank, the Economic Commission for Latin America and the Caribbean (ECLA) and the Interamerican Development Bank (IADB). In the first part of the text we characterize the particularities of each of these organizations, highlighting their relation with the processes of educational change. In the second, we approach the subject of the recommendations made by the multilateral agencies on change in the higher education systems in the world and, particularly, in the Latin American region.
