A previous study (Luwel, Verschaffel, Onghena, & De Corte, 2000) revealed that 2nd and 6th graders use at least 3 different kinds of strategies for determining different numerosities of blocks presented in square grids: (a) an addition strategy by means of which (groups of) blocks are counted (and added), (b) a subtraction strategy in which the number of empty squares is subtracted from the total number of blocks in the grid (i.e. the anchor), and (c) an estimation strategy, whereby the number of blocks is determined in a quick but imprecise way. Although 6th as well as 2nd graders used the clever subtraction strategy, the majority of 2nd graders had serious trouble with the correct determination of the anchor, resulting in huge numerosity judgement errors. Since this finding seriously complicated the testing of a number of hypotheses in that study, we replicated the above study but presented the children information about the grid size. This manipulation led to a substantial increase in the proportion of appropriate subtraction strategy users and made it possible to investigate the effect of several subject and task variables on the frequency, accuracy, and adaptiveness with which the different strategies were applied. Results are discussed in terms of the conceptual framework of Lemaire and Siegler (1995) regarding strategic change. 相似文献

Knowledge is and will be produced in order to be sold; it is and will be consumed in order to be valorised in a new production: in both cases, the goal is exchange.(Jean-Francois Lyotard, The Postmodern Condition: a report on knowledge. , 1984, p.4)
We live in a social universe in which the formation, circulation, and utilization of knowledge presents a fundamental problem.If the accumulation of capital has been an essential feature of our society, the accumulation of knowledge has not been any less so.Now, the exercise, production, and accumulation of this knowledge cannot be dissociated from the mechanisms of power; complex relations exist which must be analysed.(Michel Foucault, Remarks on Marx: conversations with Duccio Trombadori , 1991, p.165) 相似文献

This study examined the effects of reading interventions from single‐case design studies for students with and at‐risk of emotional and behavioral disorders in grades K–12 using a quantitative synthesis. Seventeen studies met the selection criteria of having one more dependent variables meeting what works clearinghouse (WWC) design standards with or without reservations. Although students’ reading performance significantly improved from baseline to intervention phases (p < 0.001), the overall weighted average effect size was weak (Tau‐U = 0.58, 95% confidence interval = [0.54, 0.63]; d = 0.29); smaller effects were found on reading comprehension. Interventions were less effective for students in secondary grades, students with a comorbid disability, and students in substantially separate settings. While no studies meeting the selection criteria were conducted in inclusive settings, the teacher provided interventions were more effective than those provided by researchers suggesting the importance of the student–teacher relationship for reading instruction. Study limitations, areas for future research, and implications for school practices are discussed. 相似文献

ABSTRACTPrevious research shows that many students find it difficult to learn computer programming. To learn computer programming includes both gaining theoretical understanding and learning to develop programmes in practice. To this end, teachers commonly design programming exercises for the students in the computer laboratory. To be able to improve the process of designing such exercises, there is a need of a more detailed understanding of the interaction between learning of theory and learning of practice in laboratory sessions. In this paper, an approach for investigating this interaction is proposed. Theoretically, the approach is based on phenomenography and variation theory. To illustrate the approach, it is demonstrated in detail how it was applied to a small but rich case of empirical data from a computer laboratory session. The main result presented here is the new approach for analysing data. In addition, the results of the case study shed preliminary light on the interaction between learning of practice and learning of theory when students work with programming assignments in the laboratory. 相似文献

In the United States, college students must complete the Free Application for Student Federal Aid (FAFSA) to access federal aid. However, many eligible students do not apply and consequently forgo significant amounts of financial aid. If students have perfect information about aid eligibility, we would expect that all eligible students complete FAFSA and no aid would go unclaimed. Using data from the National Postsecondary Student Aid Survey, I estimate a multinomial logit model which controls for all variables that contribute to aid eligibility and other student characteristics that may deter FAFSA completion. I find that students who are lower middle income, white, male and independent from parents are less likely to complete FAFSA even when they are eligible for aid. Using propensity score matching, I find that each year applicants forgo $9,741.05 in total aid (including grant and loan aid) which includes $1,281.00 of Pell Grants, $2,439.50 of the balance subsidized student loans, $1,986.65 of the balance of unsubsidized student loans, and $1,016.04 of institutional grants. These aid totals aggregate to $24 billion annually. 相似文献

AbstractAdvancements in technology have increased preschool children’s access to the Internet. Very little research has been conducted to identify pre-school-aged children’s understandings of the Internet and ramifications of being ‘online’. Without an understanding of children’s thinking about the Internet, it is difficult to provide age- and pedagogically appropriate cyber-safety education. This study developed and pilot-tested an interview schedule that focuses on the Internet thinking and cyber-safety awareness of Australian children aged 4–5 years. The schedule is informed by sociocultural theory, cyber-safety education research and approaches for researching with young children. The schedule shows potential to elicit children’s understandings of the Internet and cyber-safety awareness. Adjustments are required to allow more contextualised responses from children. 相似文献

This study estimates the relative and unique effects on changes in critical thinking of three dimensions of students' college experience: curricular exposure, formal classroom and instructional experiences, and out-of-class experiences. Students' classroom/instructional and out-of-class experiences both make positive, statistically significant, and unique contributions to gains in critical thinking above and beyond students' precollege characteristics and level of critical thinking. Theoreticians have long speculated that students' academic and nonacademic experiences jointly influence change, and this study supports that belief. The design and instruments in this study may be of interest to persons involved in assessment or the study of college impact.Paper presented at the meeting of the Association for Institutional Research, New Orleans, LA, May 1993.The National Center on Postsecondary Teaching, Learning, and Assessment is funded by the U.S. Department of Education, Office of Educational Research and Improvement (OERI), under Grant No. R117G10037.
