Strategic planning tools for large-scale technology-based assessments

Education systems are increasingly being called upon to implement new technology-based assessment systems that generate efficiencies, better meet changing stakeholder expectations, or fulfil new assessment purposes. These assessment systems require coordinated organisational effort to implement and can be expensive in time, skill and other resources. This paper explores the nexus between assessment planning and organisational strategy in the context of technology-based assessment implementation. Two planning tools, an Assessment Planning and Review Framework (the Framework) and an Assessment-Capability Matrix (the Matrix), are provided to assist organisations to manage this nexus. The Framework is a reformulation of prominent assessment design frameworks, developed for a broader, interdisciplinary audience. Its extension through the incorporation of organisational capability concerns led to the development of the Matrix. The Framework and the Matrix create an interface from principled assessment design to organisational strategy that is explored through five predominantly technology-based assessment design pathways.     

少年二三事

你一言不发地走在我旁边,我转头看你,睫毛在你眼睑下投出一片阴影你的头发有点乱,遮住了半只眼睛。我在想,我们能不能一直这样走下去？到岔路口,你挥挥手消失在暮色里。我可以感觉到：从你方向吹来的风,有恰到好处婚温度。     

Predicting Mathematics Achievement of Eighth Grade Students in Germany: An Application of Parts of the Model of Educational Productivity to the TIMSS Data

Parts of the model of educational productivity provided by Walberg and colleagues (e.g., Walberg, 1981) were tested on the basis of the German TIMSS data. Due to its national extensions, the German study allows longitudinal analyses. Structural equation modelling was applied to the data at student level. Findings supported cum grano salis the model of educational productivity. The most powerful predictors were cognitive variables. Nevertheless, motivational determinants, leisure activities and students’ gender were also significant predictors of achievement. Mass media as well as home background, that is, the educational level of parents, their job prestige and their number of books at home, had no direct impact on learning.     

Entwicklung und erste Validierung eines Tests zur Erfassung technologischer und informationsbezogener Literacy (TILT) für Jugendliche am Ende der Sekundarstufe I

The objective of this study was to develop a reliable and valid test to ascertain ICT literacy 0 = Information and Communication Technologies Literacy). It was designed as a paper-and-pencil test to ensure that it can be used flexibly. The results of two studies (pilot study: N = 308; validation sample of the final form of the test: N = 263) showed satisfactory item and scale values and indicated the one-dimensional nature of the construct. Tests of the test instruments for convergence and discrimination validity showed the expected links with computer-related pupil characteristics. To supplement this, expert reviews indicated a satisfactory content validity. Analyses of the construct validity showed that ICT literacy was clearly distinguishable from general cognitive abilities and, at the same time, possessed incremental validity in addition to other measures of computer literacy. The findings are discussed in relation to open questions about the construct validity of the test instrument.
