The aims of this research were to investigate the ways in which students in primary and secondary schools process texts and accompanying visual aids and to ascertain any developmental patterns. Think-aloud protocols were gathered from 119 Grade 5, Grade 7 and Grade 9 students while they read and studied grade-appropriate History and Science materials which contained both text and visual aids (tables, diagrams). Analyses of the think-aloud protocols yielded over 50 different processes, subsumed under 10 major categories. While the History results showed no reliable grade differences in the 10 think-aloud categories, the Science results showed developmental differences. Older students demonstrated a more diverse array of strategies, and explicit linking of text and visual aid information was not as evident in the younger students. ANOVAs following cluster analyses showed weak relationships between cluster membership and outcomes. Implications for instruction are discussed. 相似文献

The written English vocabulary of 72 deaf elementary school students of various proficiency levels in American Sign Language (ASL) was compared with the performance of 60 hearing English-as-a-second-language (ESL) speakers and 61 hearing monolingual speakers of English, all of similar age. Students were asked to retell "The Tortoise and the Hare" story (previously viewed on video) in a writing activity. Writing samples were later scored for total number of words, use of words known to be highly frequent in children's writing, redundancy in writing, and use of English function words. All deaf writers showed significantly lower use of function words as compared to their hearing peers. Low-ASL-proficient students demonstrated a highly formulaic writing style, drawing mostly on high-frequency words and repetitive use of a limited range of function words. The moderate- and high-ASL-proficient deaf students' writing was not formulaic and incorporated novel, low-frequency vocabulary to communicate their thoughts. The moderate- and high-ASL students' performance revealed a departure from findings one might expect based on previous studies with deaf writers and their vocabulary use. The writing of the deaf writers also differed from the writing of hearing ESL speakers. Implications for deaf education and literacy instruction are discussed, with special attention to the fact that ASL-proficient, deaf second-language learners of English may be approaching English vocabulary acquisition in ways that are different from hearing ESL learners. 相似文献

Upon entry into the instructional design workforce, there is a need for instructional designers to continue to hone their craft and skill development. Often times novice instructional designers are paired with experts during the onboarding process. Coaching is utilized to provide novices and those less experienced with the necessary support they need to enhance their skillset. This article explores the use of coaching in the professional development of instructional designers. Specific attention is given to theoretical approaches, models, and contexts related to coaching. 相似文献

An in-depth case study of teachers' use of image processing (a state-of-the-art computer technology used by research scientists) in biology, earth science, and physics classes within one high school science department explored issues surrounding technology implementation. The study, conducted within a districtwide, schoolwide, and classroom context, explored four areas related to the teacher's adoption of image processing: (a) teachers' background with computers outside of instructional use, (b) teachers' attitudes toward educational technology and insights gained from their experience using computers within the science curriculum, (c) training and perceived influence of district and school administrators, and (d) teachers' classroom and computer lab practices. The following factors were deemed critical in teachers' decision to use or not use image processing with their students: (a) time to thoroughly explore and master the technology so they could use it with students to explore science concepts; (b) classroom management skills specific to technology use; (c) perception of the teaching value of the technology; (d) perception of the reasonableness of administrators' expectations for technology use; and (e) understanding of how to implement inquiry-based science teaching, independent of technology issues. These factors have implications for how to help teachers use computer technology to teach high school science. © 1998 John Wiley & Sons, Inc. J Res Sci Teach 35: 297–327, 1998. 相似文献

Persistent gaps between optimistic state and pessimistic national academic performance assessment results are increasingly leading to calls for unified national standards in the US. Critics argue that these gaps reveal vast differences in how proficiency is conceptualized; however, little is known about how conceptualizations compare among large-scale US assessments. To explore this issue, the present study investigated constructs of writing proficiency implicated in 41 US state and national high school direct writing assessments by analyzing the relationships between prompt-genre demands and assessment scoring criteria. Results of this analysis suggest that national writing assessments differ as a group from state assessments in the extent to which they emphasize genre distinctions and present coherent conceptualizations of writing proficiency. The implications of these assessment variations for college preparedness are discussed. 相似文献

The present study is an evaluation of the special needs referral system in a large urban Head Start program. To assess the validity of this system, two assessments were conducted. The first examined a representative sample of 105 children who were formally referred for special needs services. The Early Intervention Screening Profile (EISP) was used to indicate the distribution of problem behaviors of these special needs children. Two independent raters evaluated all cases. Reliable evaluations revealed that all of the referred children displayed speech and language problems, with 70% showing only speech problems and 30% showing speech plus emotional and behavioral problems. The second assessment examined reports of teachers’ concerns about children program-wide by obtaining a representative sample of 203 children nominated by teachers as most likely to be identified as having special needs. Teachers completed a modified EISP. Results indicated that over 70% of the children evidenced emotional and behavioral problems with no accompanying speech difficulties and 30% displayed emotional and behavioral problems plus speech problems. Implications of referral biases were discussed. 相似文献

Understanding that mathematics is founded on reasoning and is not just a collection of rules to apply is an important message
to convey to students. Here we examined the reasoning presented in seven topics in nine Australian eighth-grade textbooks.
Focusing on explanatory text that introduced new mathematical rules or relationships, we classified explanations according
to the mode of reasoning used. Seven modes were identified, making a classification scheme which both refined and extended
previous schemes. Most textbooks provided explanations for most topics rather than presenting “rules without reasons” but
the main purpose appeared to be rule derivation or justification in preparation for practise exercises, rather than using
explanations as thinking tools. Textbooks generally did not distinguish between the legitimacies of deductive and other modes
of reasoning. 相似文献

This study aimed to provide evidence to guide decisions on the type and timing of assessments in a graduate medical programme, by identifying whether students from particular degree backgrounds face greater difficulty in satisfying the current assessment requirements. We examined the performance rank of students in three types of assessments and also calculated the relative risk of failure in the summative assessments for four cohorts over all four years of a four‐year graduate medical programme. Our findings suggest that early summative assessment may disadvantage the very students who create the diversity that the faculty values, particularly if methods such as Single Best Answer questions are used, unless students are provided with additional support in bridging their knowledge gap. Use of assessment methods such as Modified Essay Questions and Objective Structured Clinical Examinations appears to be more justifiable on educational grounds. 相似文献
