College Students’ Conceptions of Stem Cells, Stem Cell Research, and Cloning     

James P. Concannon  Marcelle A. Siegel  Kristy Halverson  Sharyn Freyermuth 《Journal of Science Education and Technology》2010,19(2):177-186

In this study, we examined 96 undergraduate non-science majors’ conceptions of stem cells, stem cell research, and cloning. This study was performed at a large, Midwest, research extensive university. Participants in the study were asked to answer 23 questions relating to stem cells, stem cell research, and cloning in an on-line assessment before and after instruction. Two goals of the instruction were to: (1) help students construct accurate scientific ideas, and (2) enhance their reasoning about socioscientific issues. The course structure included interactive lectures, case discussions, hands-on activities, and independent projects. Overall, students’ understandings of stem cells, stem cell research, and cloning increased from pre-test to post-test. For example, on the post-test, students gained knowledge concerning the age of an organism related to the type of stem cell it possesses. However, we found that some incorrect ideas that were evident on the pre-test persisted after instruction. For example, before and after instruction several students maintained the idea that stem cells can currently be used to produce organs.  相似文献   

Non-Science Majors’ Critical Evaluation of Websites in a Biotechnology Course     

Kristy L. Halverson  Marcelle A. Siegel  Sharyn K. Freyermuth 《Journal of Science Education and Technology》2010,19(6):612-620

Helping students develop criteria for judgment and apply examination skills is essential for promoting scientific literacy. With the increasing availability of the Internet, it is even more essential that students learn how to evaluate the science they gather from online resources. This is particularly true because publishing information on the web is not restricted to experts, and content quality can vary greatly across websites. The responsibility of evaluating websites falls upon the user. Little research has examined undergraduates’ evaluation of web sites in science classes. The purpose of this study was to investigate on which websites college students selected and how they evaluated the websites used when developing individual positions about stem-cell research. We used a qualitative approach in search of patterns in undergraduates’ website selection and evaluation criteria. We found that students used a variety of web resources from eleven types of websites to complete their independent research report. Students also used eleven evaluation criteria to evaluate these sources, some useful (e.g., credibility) and some not useful (e.g., readability). We found that university students struggled with critically evaluating online resources. Undergraduates need prompts to learn how to critically evaluate the science content provided within websites. This type of scaffold can facilitate useful evaluation and promote critical thinking required for becoming scientifically literate.  相似文献

The role of question type and reading ability in reading comprehension     

Naomi F. Tal  Linda S. Siegel  Michael Maraun 《Reading and writing》1994,6(4):387-402

Performance on a standardized reading comprehension test reflects the number of correct answers readers select from a list of alternate choices, but fails to provide information about how readers cope with the various cognitive demands of the task. The aim of this study was to determine whether three groups of readers: normally achieving (NA), poor comprehenders (CD), with no decoding disability, and reading disabled (RD), poor comprehenders with poor decoding skills, differed in their ability to cope with reading comprehension task demands. Three task variables reflected in the question-answer relations that appear on standardized reading comprehension tests were identified.Passage Independent (PI) question can be answered with reasonable accuracy based on the reader's prior knowledge of the passage content.Inference (INFER) questions required the reader to generate an inference at the local or global test level.Locating (LOCAT) questions require the reader to match the correct answer choice to a detail explicitly stated in the text either verbatim or in paraphrase form. The relations among reader characteristics, cognitive task factors and reading comprehension test scores were analyzed using a structural relations equation with LISREL. It was found that the three reading groups differed with respect to the underlying relationship between their performance on specific question-answer types and their standardized reading comprehension score. For the NA group, a high score on PI was likely to be accompanied by a low score on INFER, whereas in the CD and RD groups, PI and INFER are positively related. The finding of a negative relationship between background knowledge and inference task factors for normally achieving readers suggests that even normal readers may have comprehension difficulties that go undetected on the basis of a standardized scores. This study indicates that current comprehension assessments may not be adequate for assessing specific reading difficulties and that more precise diagnostic tools are needed.  相似文献   

The relationship between IQ and reading disabilities in English-speaking Canadian and Spanish children     

Jiménez JE  Siegel LS  López MR 《Journal of learning disabilities》2003,36(1):15-23

This study was designed to examine the role of intelligence (IQ) in the definition of reading disabilities (RD) in languages with different orthographic systems. A sample of 94 Spanish children and 157 English-speaking Canadian children with RD was classified into four groups on the basis of IQ scores from the Wechsler Intelligence Scale for Children-Revised (< 80; 81-90; 91-109; 110-140). We examined the reading and spelling skills of Canadian and Spanish children as a function of Full Scale, Verbal, and Performance IQ scores. Significant differences between the languages were found when reading performance was analyzed as a function of Verbal IQ scores, in that there were some differences between the groups of Canadian children with RD but not between the groups of Spanish children. The Canadian children with Verbal IQ scores < 80 demonstrated relatively lower performance in reading and spelling skills than the Canadian groups with higher IQ scores. There were differences in reading tasks as a function of Performance IQ in English but not in Spanish. The differences in the role of IQ as a function of orthographic systems may relate to the greater significance of visual-orthographic as opposed to phonological processing in English.  相似文献   

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     

Fuk-chuen Ho  Linda Siegel 《Reading and writing》2012,25(7):1547-1571

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
