Recouping and rethinking the effects of summer vacation on reading achievement

Vacations may have detrimental effects on maths and spelling performance, but the findings for reading are less conclusive. The purpose of this study was to analyse the effects of summer vacation on early literacy skills of young children. Participants included rising first and second‐graders, most of whom were at‐risk, struggling readers. No evidence of summer setback was evident for this sample of children; in fact, gains in reading (or, recoupment of any losses) were more common in children performing at lower levels than for those with higher scores at the end of the school year. Our outcomes are different from those reported by other researchers. We explain this with attention to the content of our comparisons, the grade levels investigated and measures used to assess performance, and discuss implications for future research based on our findings.  相似文献

The communication of laboratory investigations by university entrants

The purpose of the study reported here was to analyse the ways in which unversity entrant science students carry out and communicate experimental activities and to identify a model to explain characteristic communication practices. The study was prompted by a need to inform the development of an introductory laboratory course. The students studied shared an educational background characterised by a lack of experience with laboratory work and scientific writing. Seven groups of three students were studied. The investigative strategies of these groups were observed. Laboratory reports were used to identify the ways in which students communicated these strategies. Data are presented that show a discrepancy between the strategies used and those reported. The results suggest that: (i) students' perceptions of the purpose of a laboratory task influence their decisions on what to report; (ii) understandings of laboratory procedures greatly influence their decision on what to report and on how much detail to include in a report and; (iii) knowledge of discourse rules contributes to effective reporting. It is concluded that students' communication of an investigation results from the differential operation of various perceptual filters that determine both the procedural and discourse elements of their reports. It is recommended that the communication of science should be taught explicitly and alongside the procedures and concepts of science. © 2000 John Wiley & Sons, Inc.
