PISA:数学素养的界定与测评

数学素养是国际学生评价项目(The Programme International Student Assessment,以下简称PISA)2003年的重点测评项目。PISA认为数学素养这一领域不仅要求学生掌握适应未来社会挑战的数学技能,而且要求学生学会分析、推理,在各种情境、领域中,通过提出问题,分析问题和解决问题来有效地传递观点。因此,PISA对数学素养的测评重点与以前的其它测评不同,如第三次国际数学和科学教育研究(IEA/TIMSS),他们的评价结构是基于成员国的国家课程的共同要素而进行,但PISA评估的重点不是     

天津学生数学学习的性别差异——来自PISA的结果

数学学习的性别差异一直是人们关心的问题。PISA 2012测评结果显示,虽然天津男生与女生数学学习成绩不存在差异,但男女生数学学习的驱动力、动机和自我信念还是有明显差异。与男生相比,女生学习的坚持性、问题解决的开发性、对自身解决数学问题能力的自信更差,而数学焦虑更强,更倾向于将数学学习失败的责任归咎于自身以外的因素。     

Generalizability of Large-Scale Performance Assessments in Science: Promises and Problems

This study provides empirical evidence about the sampling variability and generalizability (reliability) of a statewide science performance assessment. Results at both individual and school levels indicate that task-sampling variability was the major source of measurement error in the performance assessment; rater-sampling variability was negligible. Adding more tasks improves the generalizability of the measurement. For the school-level assessment, the variation of performance among students within a school was larger than the variation among schools. Increasing the number of students taking a test within a school thus increases the generalizability of the assessment. Finally, the allocation of students in a matrix-sampling design is compared to a studentscrossed-with-tasks design. The former would require fewer tasks per student than the latter to build a generalizable measure of school performance.

Training and Scoring Issues Involved in Large-Scale Writing Assessments

Many states are implementing direct writing assessments to assess student achievement. While much literature has investigated minimizing raters' effects on writing scores, little attention has been given to the type of model used to prepare raters to score direct writing assessments. This study reports on an investigation that occurred in a state-mandated writing program when a scoring anomaly became apparent once assessments were put in operation. The study indicates that using a spiral model for training raters and scoring papers results in higher mean ratings than does using a sequential model for training and scoring. Findings suggest that making decisions about cut-scores based on pilot data has important implications for program implementation.

Impact of Design Effects in Large-Scale District and State Assessments

This article proposes that sampling design effects have potentially huge unrecognized impacts on the results reported by large-scale district and state assessments in the United States. When design effects are unrecognized and unaccounted for they lead to underestimating the sampling error in item and test statistics. Underestimating the sampling errors, in turn, results in unanticipated instability in the testing program and an increase in Type I errors in significance tests. This is especially true when the standard error of equating is underestimated. The problem is caused by the typical district and state practice of using nonprobability cluster-sampling procedures, such as convenience, purposeful, and quota sampling, then calculating statistics and standard errors as if the samples were simple random samples.     

Measurement,Sampling, and Equating Errors in Large-Scale Assessments

In large-scale assessments, such as state-wide testing programs, national sample-based assessments, and international comparative studies, there are many steps involved in the measurement and reporting of student achievement. There are always sources of inaccuracies in each of the steps. It is of interest to identify the source and magnitude of the errors in the measurement process that may threaten the validity of the final results. Assessment designers can then improve the assessment quality by focusing on areas that pose the highest threats to the results. This paper discusses the relative magnitudes of three main sources of error with reference to the objectives of assessment programs: measurement error, sampling error, and equating error. A number of examples from large-scale assessments are used to illustrate these errors and their impact on the results. The paper concludes by making a number of recommendations that could lead to an improvement of the accuracies of large-scale assessment results.     

DIF Detection and Interpretation in Large-Scale Science Assessments: Informing Item Writing Practices

Differential item functioning (DIF) analyses are a routine part of the development of large-scale assessments. Less common are studies to understand the potential sources of DIF. The goals of this study were (a) to identify gender DIF in a large-scale science assessment and (b) to look for trends in the DIF and non-DIF items due to content, cognitive demands, item type, item text, and visual-spatial or reference factors. To facilitate the analyses, DIF studies were conducted at 3 grade levels and for 2 randomly equivalent forms of the science assessment at each grade level (administered in different years). The DIF procedure itself was a variant of the "standardization procedure" of Dorans and Kulick (1986) and was applied to very large sets of data (6 sets of data, each involving 60,000 students). It has the advantages of being easy to understand and to explain to practitioners. Several findings emerged from the study that would be useful to pass on to test development committees. For example, when there was DIF in science items, MC items tended to favor male examinees and OR items tended to favor female examinees. Compiling DIF information across multiple grades and years increases the likelihood that important trends in the data will be identified and that item writing practices will be informed by more than anecdotal reports about DIF.     

Gender Differences on the Math Subtest of the Scholastic Aptitude Test may be Culture-Specific

Cross-cultural studies can shed new light on theories of gender differences in cognition. In the present study, Chinese students were given items from the math subtest of the Scholastic Aptitude Test (SAT) that have been found to produce the largest gender differences in American students. The authors describe how four different explanations of gender differences make different predictions regarding the possible size of the gender difference in Chinese students. Consistent with the Differential Coursework view but contrary to the predictions of several other views, the results revealed no difference in performance on the SAT items between Chinese males and females.     

Examinee Non-Effort on Contextualized and Non-Contextualized Mathematics Items in Large-Scale Assessments

In this study it is investigated to what extent contextualized and non-contextualized mathematics test items have a differential impact on examinee effort. Mixture item response theory (IRT) models are applied to two subsets of items from a national assessment on mathematics in the second grade of the pre-vocational track in secondary education in Flanders. One subset focused on elementary arithmetic and consisted of non-contextualized items. Another subset of contextualized items focused on the application of arithmetic in authentic problem-solving situations. Results indicate that differential performance on the subsets is to a large extent due to test effort. The non-contextualized items appear to be much more susceptible to low examinee effort in low-stakes testing situations. However, subgroups of students can be found with regard to the extent to which they show low effort. One can distinguish a compliant, an underachieving, and a dropout group. Group membership is also linked to relevant background characteristics.     

A comparison of PISA and TIMSS 2003 achievement results in mathematics

This study compares the Programme for International Student Assessment (PISA) 2003 Mathematics results with the Trends in International Mathematics and Science Study (TIMSS) 2003 Grade 8 mathematics results, using country mean scores for 22 participants of both studies. It is found that Western countries generally performed better in PISA than in TIMSS, and Eastern European and Asian countries generally performed better in TIMSS than in PISA. Furthermore, two factors, content balance and years of schooling, can account for 93% of the variation between the differential performance of countries in PISA and TIMSS. Consequently, the rankings of countries in the two studies can be reconciled to a reasonable degree of accuracy.     

Gender and Gender Identity Differences in Learning Styles

In the past decade, extensive research on gender and learning styles has produced a multitude of findings: gender differences in learning styles are small on average, but across studies quite different results are observed. In the present study, this heterogeneity is the central focus of our attention. Two possible interpretations concerning the educational context and the concept of gender identity are investigated: the teacher and the subject he or she teaches. Besides the variable gender as a dichotomous variable, the variable gender identity is included to reflect the theoretical standpoint of the social construction of gender differences. Using multivariate techniques on a data set of 432 adult secondary students, the observed relations between gender, gender identity and learning styles are described. Gender identity turns out to explain more variance in the use of learning styles compared to gender. Furthermore, it is shown that gender (identity) differences in learning styles do not vary across teachers and, with one exception, they do not vary across subjects.     

The LAAS: A Computerized Scoring System for Small- and Large-Scale Developmental Assessments

The evaluation of developmental interventions has been hampered by a lack of practical, reliable, and objective developmental assessment systems. This article describes the construction of a domain-general computerized developmental assessment system for texts: the Lexical Abstraction Assessment System (LAAS). The LAAS provides assessments of the order of hierarchical complexity of oral and written texts, employing scoring rules developed with predictive discriminant analysis. The LAAS is made possible by a feature of conceptual structure we call hierarchical order of abstraction, which produces systematic quantifiable changes in lexical composition with development. The LAAS produces scores that agree with human ratings of hierarchical complexity more than 80% of the time within one-third of a complexity order across 6 complexity orders (18 levels), spanning the portion of the lifespan from about 4 years of age through adulthood. This corresponds to a Kendall's tau of .93.     

Comparisons among Designs for Equating Mixed-Format Tests in Large-Scale Assessments

In this study we examined variations of the nonequivalent groups equating design for tests containing both multiple-choice (MC) and constructed-response (CR) items to determine which design was most effective in producing equivalent scores across the two tests to be equated. Using data from a large-scale exam, this study investigated the use of anchor CR item rescoring (known as trend scoring) in the context of classical equating methods. Four linking designs were examined: an anchor with only MC items, a mixed-format anchor test containing both MC and CR items; a mixed-format anchor test incorporating common CR item rescoring; and an equivalent groups (EG) design with CR item rescoring, thereby avoiding the need for an anchor test. Designs using either MC items alone or a mixed anchor without CR item rescoring resulted in much larger bias than the other two designs. The EG design with trend scoring resulted in the smallest bias, leading to the smallest root mean squared error value.
