Students’ attitudes towards interdisciplinary education: a course on interdisciplinary aspects of science and engineering education

A course entitled ‘Science and Engineering Education: Interdisciplinary Aspects’ was designed to expose undergraduate students of science and engineering education to the attributes of interdisciplinary education which integrates science and engineering. The core of the course is an interdisciplinary lesson, which each student is supposed to teach his/her peers. Sixteen students at advanced stages of their studies attended the course. The research presented here used qualitative instruments to characterise students’ attitudes towards interdisciplinary learning and teaching of science and engineering. According to the findings, despite the significant challenge which characterises interdisciplinary teaching, a notable improvement was evident throughout the course in the percentage of students who expressed willingness to teach interdisciplinary classes in future.     

Mastery learning,rewriting assignments and student learning of criminal justice research methods

This research examines the application of mastery learning theory to the teaching of criminal justice research methods. Mastery learning has students learn each module before proceeding to the next one. Criminal justice research methods is amenable to mastery learning because the course content is cumulative; students need to know each step before proceeding to the next one. Mastery learning was implemented by having students rewrite exercises until they obtained perfect scores. It was tested in three classes taught by the same instructor. Student learning was measured by comparing the difference in scores on a pretest examination with scores on a post-test examination. The results indicated that the better students performed on the exercises, the more they improved on the final examination over the initial examination. The more students rewrote assignments, the better they performed on the assignments and subsequently, the more they improved on the final examination. Students who averaged between one and two rewrites maximized improvement on the examination. The results suggest that mastery learning theory is an effective method of teaching research methods. Although it is more time consuming than traditional methods, it is beneficial to students who are trying to learn difficult material for the first time.     

Citation Help in Databases: The More Things Change,the More They Stay the Same

In 2005, the authors reviewed citation help in databases and found an error rate of 4.4 errors per citation. This article describes a follow-up study that revealed a modest improvement in the error rate to 3.4 errors per citation, still unacceptably high. The most problematic area was retrieval statements. The authors conclude that librarians should include citation features in the evaluation of databases and should open a dialogue with vendors about the importance of providing accurate, reliable information about citations to students.     

A HUMANISTIC HIGHER EDUCATION PROGRAMME

This article proposes a concrete educational programme ‐ based on the reappropriation of the German humanistic conception of the modern university ‐ for a reunification of the “two cultures”, humanistic and scientific, within the framework of the postmodern university. The first step will be to clarify the demise of the cultural and educational role of postmodern universities (first section); secondly, to present the humanistic conception of the university, implemented at the University of Berlin established by von Humboldt at the beginning of the nineteenth century, as both a desirable and possible conceptual foundation for the revitalization of the cultural role of the university (second section); thirdly, to delineate a concrete educational programme based on a reappropriation of the humanistic conception (third section); and finally, in a short section (the fourth), to describe two specific characteristics of the suggested programme.     

Statistical Learning and Spelling: Older Prephonological Spellers Produce More Wordlike Spellings Than Younger Prephonological Spellers

The authors analyzed the spellings of 179 U.S. children (age = 3 years, 2 months–5 years, 6 months) who were prephonological spellers, in that they wrote using letters that did not reflect the phonemes in the target items. Supporting the idea that children use their statistical learning skills to learn about the outer form of writing before they begin to spell phonologically, older prephonological spellers showed more knowledge about English letter patterns than did younger prephonological spellers. The written productions of older prephonological spellers were rated by adults as more similar to English words than were the productions of younger prephonological spellers. The older children s spellings were also more wordlike on several objective measures, including length, variability of letters within words, and digram frequency.     

Frequency analyses of prephonological spellings as predictors of success in conventional spelling

The present study explored how children's prephonological writing foretells differential learning outcomes in primary school. The authors asked Portuguese-speaking preschool children in Brazil (mean age 4 year 3 months) to spell 12 words. Monte Carlo tests were used to identify the 31 children whose writing was not based on spellings or sounds of the target words. Two and a half years later, the children took a standardized spelling test. The more closely the digram (two-letter sequence) frequencies in the preschool task correlated with those in children's books, the better scores the children had in primary school, and the more preschoolers used letters from their own name, the lower their subsequent scores. Thus, preschoolers whose prephonological writing revealed attentiveness to the statistical properties of text subsequently performed better in conventional spelling. These analytic techniques may help in the early identification of children at risk for spelling difficulties.
