This study investigated the effects of a 12-week language-enriched phonological awareness instruction on 76 Hong Kong young children who were learning English as a second language. The children were assigned randomly to receive the instruction on phonological awareness skills embedded in vocabulary learning activities or comparison instruction which consisted of vocabulary learning and writing tasks but no direct instruction in phonological awareness skills. They were tested on receptive and expressive vocabulary, phonological awareness at the syllable, rhyme and phoneme levels, reading, and spelling in English before and after the program implementation. The results indicated that children who received the phonological awareness instruction performed significantly better than the comparison group on English word reading, spelling, phonological awareness at all levels and expressive vocabulary on the posttest when age, general intelligence and the pretest scores were controlled statistically. The findings suggest that phonological awareness instruction embedded in vocabulary learning activities might be beneficial to kindergarteners learning English as a second language.  相似文献

The purpose of our study was to assess how an academic health center (AHC) mentor academy program affected mentor competence and optimized the mentor–mentee relationship. Mixed methods were used to assess the effectiveness of an AHC mentor program at a clinical translational science institute (CTSI). Twenty biomedical research faculty mentors took a validated survey and submitted reflective writings to discover if they corroborated or refuted statistically significant survey results. There was a significant improvement in participants’ confidence of mentor skills, integral mentoring quality, and the extent to which they fulfill mentees’ expectations. Males provided constructive feedback and helped mentees develop goal strategies more often compared to females. Reflective writings supported these findings yet refuted two survey findings. The use of a mixed methods approach offers novel insight into how mentoring programs benefit translational research mentoring capacity building and raises questions about the sole use of surveys as evidence of program effectiveness.  相似文献

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.  相似文献

The purpose of this study was to explore the relationship between department/division chairpersons' interpersonal behavior and their perceived leadership effectiveness. The Departmental Evaluation of Chairperson Activities for Development (DECAD) system was used to determine the department chairpersons' administrative effectiveness. Element B, developed by Will Schutz, was used to assess the chairpersons' interpersonal behavioral characteristics. The participants were department/division chairpersons and full-time faculty members from 15 of the 17 public and private community colleges in a southern state. Survey packets were mailed to faculty members and department/ division chairpersons in the humanities and social sciences divisions. Sixty-seven percent of the faculty responded and 93% of the chairpersons responded. Statistical analyses revealed significant differences in the dependent variables of received inclusion, perceived inclusion, and wanted inclusion interpersonal behaviors between the ineffective and effective chairs. These findings suggest that effective department chairpersons possess a need to maintain and establish interaction with others. Also, effective chairpersons were perceived to be, and want to be, included by others.  相似文献

The central purposes of this study were to review the development and evolution of the Scientific Attitude Inventory (SAI) and then reevaluate the psychometric properties of the revised form of the SAI, the Scientific Attitude Inventory II (SAI‐II). The SAI‐II was administered to a convenience sample of 543 middle and high school students from five teachers in four schools in four school districts in San Antonio, Texas, at the beginning of the 2004–2005 school year. Confirmatory factor analysis on the full data set failed to support the existence of a 12‐factor structure (as proposed by the scale developers) or a one‐factor structure. The data were then randomly divided into exploratory [exploratory factor analysis (EFA)] validation and confirmatory [confirmatory factor analysis (CFA)] cross‐validation sets. Exploratory and confirmatory models yielded a three‐factor solution that did not fit the data well [χ2 (321) = 646, p < .001; RMSEA = .061 (.90 CI = .054–.068); and CFI = .81]. The three factors were labeled “Science is About Understanding and Explaining” (13 items), “Science is Rigid” (6 items), and “I Want to Be a Scientist” (8 items). The α‐coefficients for these three factors ranged from 0.59 to 0.85. Whether these identified subscales are valid will require independent investigation. In this sample, and consistent with prior publications, the SAI‐II in its current form did not have satisfactory psychometric properties and cannot be recommended for further use. © 2008 Wiley Periodicals, Inc.
