Strategic aspects of children’s numerosity judgement

A previous study (Luwel, Verschaffel, Onghena, & De Corte, 2000) revealed that 2^nd and 6^th 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 6^th as well as 2^nd graders used the clever subtraction strategy, the majority of 2^nd 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.     

Influences affecting the development of students' critical thinking skills

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.

The origins and aims of Epistemics

This is the first of two articles describing the nature and historical development of the author's work on Epistemics. The author originally conceived Epistemics as the science of the structure and transmission of human knowledge, but this conception was later elaborated to enable separate emphasis to be given to the human and instrumental aspects of knowledge transmission. Part I of the paper relates the concerns of Epistemics to Instructional Science. Part II of the paper relates Epistemics to insight deriving from the Brain Sciences.     

传统数学评价之"缺憾"——以一个租船问题为例

传统评价未能正确地反映数学的本质，传统的数学评价系统希望贴近常模分布．传统的数学评价是“片段”和“缩水”的评价．评价的标准间接规定了学生的问题解决模式，被评价的指标体系影响了学习的发生方式，评价的标准也不断加剧僵化数学观的塑造．数学开放题为思维方式和过程提供了更多空间．开放题的质化评价弥补了传统的数学评价存在的某些缺陷，但这种评价与传统评价相比，确实耗费更多时间．利用开放题的质化评价是未来数学评价的方向．     

Consistency of Angoff-Based Predictions of Item Performance: Evidence of Technical Quality of Results From the Angoff Standard Setting Method

Judgmental standard-setting methods, such as the Angoff(1971) method, use item performance estimates as the basis for determining the minimum passing score (MPS). Therefore, the accuracy, of these item peformance estimates is crucial to the validity of the resulting MPS. Recent researchers (Shepard, 1995; Impara & Plake, 1998; National Research Council. 1999) have called into question the ability of judges to make accurate item performance estimates for target subgroups of candidates, such as minimally competent candidates. The propose of this study was to examine the intra- and inter-rater consistency of item performance estimates from an Angoff standard setting. Results provide evidence that item pelformance estimates were consistent within and across panels within and across years. Factors that might have influenced this high degree of reliability, in the item performance estimates in a standard setting study are discussed.     

Development of a distance education assessment instrument

The study described in this article takes the view that distance education programs are dynamic systems with multiple constituencies. Literature on distance education programs as complex systems and on the critical constituency approach to program evaluation was used to guide the development of a questionnaire designed to assess the components of a distance education program. Instrument development was conducted in four phases using both quantitative and qualitative methods. The data from this study suggest that there are four major components of effectiveness in distance education programs: instruction, management, telecommuting, and support. Within each of these components there are from two to five subcomponents, 14 components in all, which can be used to assess distance education programs. The assessment scale which was developed measures these four components and their subcomponents.
