Designing a formative e‐assessment: Latent class analysis of early reading skills

Computer‐based testing, or e‐assessment, has the potential to deliver immediate results for the benefit of schools. This paper describes a project that aimed to exploit this potential by designing e‐assessments where the results were intended for use by teachers in planning the next steps in teaching and learning: low‐stakes, formative assessment. A pair of tests assessing early reading was developed, with the test items based on a range of distinct skills, including phonological segmentation, rhyming and word recognition. The tests were administered on a screen with the questions presented aurally and visually. In trials, a total of 1345 test results were obtained from pupils aged 5–7 years from 26 schools. Latent class analysis was used to identify patterns of performance within the data. Four latent classes were distinguished, each characterised by a pattern of responses related to the different test items. The strengths and weaknesses in early reading skills implied by each of these latent classes were described in terms of formative ‘profiles’ provided for teachers in an online reporting package together with indicators for the next steps in teaching. The research resulted in an automated marking and analysis system that can be genuinely formative.     

I. CHILDREN IN INSTITUTIONAL CARE: DELAYED DEVELOPMENT AND RESILIENCE

Children exposed to institutional care often suffer from “structural neglect” which may include minimum physical resources, unfavorable and unstable staffing patterns, and socially emotionally inadequate caregiver‐child interactions. This chapter is devoted to the analysis of the ill effects of early institutional experiences on resident children's development. Delays in the important areas of physical, hormonal, cognitive, and emotional development are discussed. The evidence for and against the existence of a distinctive set of co‐occurring developmental problems in institutionalized children is weighed and found to not yet convincingly demonstrate a “postinstitutional syndrome.” Finally, shared and nonshared features of the institutional environment and specific genetic, temperamental, and physical characteristics of the individual child are examined that might make a crucial difference in whether early institutional rearing leaves irreversible scars.     

Distance education via the Internet: the student experience

This is the second in a series of papers that describes the use of the Internet on a distance-taught undergraduate Computer Science course (Thomas et al ., 1998). This paper examines students' experience of a large-scale trial in which students were taught using electronic communication exclusively. The paper compares the constitution and experiences of a group of Internet students to those of conventional distance learning students on the same course. Learning styles, background questionnaires, and learning outcomes were used in the comparison of the two groups. The study reveals comparable learning outcomes with no discrimination in grade as the result of using different communication media. The student experience is reported, highlighting the main gains and issues of using the Internet as a communication medium in distance education. This paper also shows that using the Internet in this context can provide students with a worthwhile experience.     

Positive findings for plasma polymer (meth)acrylate thin films in heritage protective applications

Plasma technology is an innovative environmental friendly process that can be an option to the conventional methods for materials’ processing. Nonequilibrium low pressure plasma found efficiency as a nondestructive method for the treatment of different materials, many of them belonging to the cultural heritage, in some proper operations such as: atomic-level cleaning, decontamination, thin film deposition. In the paper, the low pressure nonequilibrium plasma is applied for the deposition of plasma polymer poly(methyl methacrylate-co-ethyl acrylate) P(MMA-co-EtA) thin films on natural aged paper, with the consolidation and protective aim. To verify the plasma polymer applicability for paper protection and consolidation, the film is aged accelerated by UV radiation and the structural and morphological changes are evaluated by FTIR spectroscopy, color/gloss measurement, contact angle and AFM.

Multimedia Science Kits: A Museum Project on Women Scientists and Their Research

The University of Nebraska State Museum (UNSM) is creating multimedia outreach kits on the research of women scientists. The collaborative effort has included Nebraska Educational Telecommunications, curricula developers, biographers, graphic designers, and evaluators. The goal of the project is to increase the number of girls interested in pursuing careers in science, and to this end, women scientists are presented as role models. Wonderwise kits target students in grades four through six through student-centered, inquiry-based activities, specimens and tools, videos of the scientists working in the field, resource-based CD-ROMs, and short biographies of the scientists. This project presents a model of how museums can collaborate with schools to improve science education on a statewide basis.
