Modeling Skipped and Not‐Reached Items Using IRTrees

When dealing with missing responses, two types of omissions can be discerned: items can be skipped or not reached by the test taker. When the occurrence of these omissions is related to the proficiency process the missingness is nonignorable. The purpose of this article is to present a tree‐based IRT framework for modeling responses and omissions jointly, taking into account that test takers as well as items can contribute to the two types of omissions. The proposed framework covers several existing models for missing responses, and many IRTree models can be estimated using standard statistical software. Further, simulated data is used to show that ignoring missing responses is less robust than often considered. Finally, as an illustration of its applicability, the IRTree approach is applied to data from the 2009 PISA reading assessment.     

Secondary schools included: a literature review

For over a decade, inclusive discourse comprises the development of a school for all, both in primary and in secondary education. Facing long-standing barriers for effective comprehensive education, secondary schools show specific interests, strengths and needs in a school-wide movement towards inclusion. Reviewing literature of recent research in inclusion in secondary schools (2000–2012), current interests represent inclusive culture, policy and practices, although the balance between each of these dimensions is unequal. A large number of studies report on attitudes towards inclusion, followed by inclusive practice. A lower number of studies deal with policy issues. Staff attitudes towards inclusion, access to the general curriculum, peer support, self-determination strategies and collaborative practices in specific subject areas were identified as major topics of investigation. Considerable attention has also been paid to peer attitudes, self-advocacy and student grouping. While the adolescent perspective is emphasised, little room is left for parental involvement. Also, the central role of administrators and professional development of staff has been underexposed in current research on secondary inclusion.

ICT learning experience and research orientation as predictors of ICT skills and the ICT use of university students

Since our first studies of information and communications technology (ICT) skills and ICT use at universities in 2004, ICT and its use by students has changed greatly. In order to obtain a more detailed picture of ICT skills, we first construct a new instrument to measure the self-perception of ICT skills (49 items) and of ICT use (53 items) by students. This allows us to find some patterns for ICT skills and ICT use. In order to explain these patterns, two basic hypotheses are formulated. The first suggests that positive ICT learning experiences at home, in school, and with peers could contribute to mastering a higher level of ICT skills and more frequent use of ICT among bachelor’s students, a hypothesis that aligns with Dewey’s learning theory. The second hypothesis suggests that there is a similarity between the characteristics of information systems and scientific research, and that students who identify more with scientific research would be more likely to have greater ICT skills and a higher frequency of ICT use. Both hypotheses are tested among bachelor’s students, using some important contextual variables (gender, domain of study, ICT course in secondary school or at university, and education level of parents). It can be concluded that there is a relationship between the ICT learning experience and the research-oriented identity commitment of bachelor’s students on the one hand, and their command of ICT skills and the frequency of use of computers, ICT instruments, and ICT programs on the other.     

社会期待的位移与高等教育经营范式的转换

自扩招政策出台以来,我国高等教育发展在短短五年时间里,实现了一次历史性的跨越,高等教育总体规模扩大了一倍,并从精英化阶段过渡到大众化阶段。随着扩招工作的不断推进,关于"质量滑坡"、"大学生过剩"的警示与担忧十分强烈,从而引发高等教育社会期待的转变。包括高等学校办学指导思想、教育教学质量标准、培养方式等方面在内的经营范式的转换,成为制约我国高等教育发展亟待解决的根本性问题。     

The demand for higher education in The Netherlands, 1950–1999

This paper investigates the role of economic factors in the university enrollment decision for the post-war period in The Netherlands. We include those factors standing at the heart of the idea that education is an investment. The econometric results suggest that students are not responsive to tuition fees, but financial support (the sum of loans and grants), the college premium on future labor market earnings, and the alternative wage are important in the enrollment decision.
