Identification of sub-types of students with learning disabilities in reading and its implications for Chinese word recognition and instructional methods in Hong Kong primary schools

This paper consists of three studies. The first study aimed to identify sub-types of students with learning disabilities in reading. Based on the dual-route model of reading, words may be read using either a lexical (words are recognized as wholes) or a sub-lexical (words are recognized through grapheme-phoneme correspondence) procedure. Castles and Coltheart (1993) provided evidence for the existence of these two mechanisms in English reading. They suggested that deficits in one and/or the other mechanism would lead to different patterns of reading disability. Surface dyslexia results from an impairment of the lexical procedure with an intact phonological route to reading. Phonological dyslexia results from a deficit in the grapheme-phoneme transformation mechanism. A higher percentage of surface dyslexia was identified in the present study. The aim of the second study was to analyze reading errors to support the existence of surface and phonological dyslexic patterns in Chinese reading. The results showed that students with surface dyslexic pattern made more phonological errors, whereas students with phonological dyslexic pattern made more semantic errors. These two studies indicate that students with learning disabilities could have different strengths and weaknesses and could have different preferences for recognizing Chinese characters and different responses to instructional methods. The third study was designed to test the effects of different teaching methods and different kinds of Chinese characters on students with learning disabilities. In general, the analytic method was found more effective for students with surface dyslexic pattern and the whole-word method for those with the phonological dyslexic pattern. The findings of this study showed the importance of identifying the strengths of the different sub-types of readers and the need to choose appropriate instructional methods accordingly.     

Cypriot libraries

Abstract

This paper delineates the historical retrospective and current status of library and information science education in China. Emphases are on analysing the similarities and differences in origin, evolution, scale, structure, curriculum, faculty and students in library and information science education between China and the United States. Possible causes are also explored. The golden age of China’s library education in the 1980s and the disastrous Great Cultural Revolution, both clearly show that China’s political situation has a greater influence on its library education than does the US political situation on American library education. On the other hand, it seems that the impact of financial resources and job market for librarians on American library education is more influential than on China’s. It has become clear that China’s substantial progress in the 1980s has reduced the gap between the two countries.

The Interface of Opinion,Understanding and Evaluation While Learning About a Socioscientific Issue

Scientific literacy is an important goal for science education, especially within controversial socioscientific issues. In this study, we analysed 143 students' research reports about stem cell research (SCR) for how they addressed specific source evaluation criteria provided within the assignment. We investigated students' opinions about SCR, how they used the evaluation criteria to evaluate online sources and whether the evaluation criteria and/or the specific sources influenced their opinion and/or understanding of SCR. We found that most of the students supported some form of SCR and reported that their sources were credible and contained more factual information than opinions. Students critiqued the language of the authors, as well as status in their respective fields, along with the content within each source. Additionally, students reported that their sources influenced their content knowledge, but had little influence regarding their SCR opinions. Through this work, we present a new working model and suggest the need for additional research about the understudied interface of opinion, understanding and evaluation within the context of important socioscientific issues. Students' opinions and content knowledge, located at the model's centre, influence and are influenced by the research topic, the sources used, the evaluation criteria and the evaluation of the sources that students use to provide evidence for claims.     

McLuhan,Mass Media,and Education

A lesson in Gestalt theory was presented to college students via lecture, videotape, audiotape, and printed notes. Comparing the effectiveness of various mass media, it was found that the group with the printed notes performed best on an examination of the material, followed by the lecture and videotape groups who fared equally well, and by the audio tape group who did the poorest. A test of prolonged retention two months later revealed that each group showed a significant drop in level of retention, but the relationship between the various medias remained the same. The general findings gave no support to McLuhan’s theory that the medium is the message. The content of the material and the attitude of the students greatly influenced the effectiveness of the media.
