This investigation analyzed goals from the Individual Educational Programs (IEPs) of 54 high school students with diagnosed
reading disabilities in basic skills (decoding and/or word identification). Results showed that for 73% of the students, the
IEPs written when they were in high school failed to specify any objectives regarding their acute difficulties with basic
skills. IEPs from earlier points in the students’ educations were also reviewed, as available. For 23 of the students, IEPs
were present in the students’ files for three time points: elementary school (ES), middle school (MS), and high school (HS).
Another 20 students from the sample of 54 had IEPs available for two time points (HS and either MS or ES). Comparisons with
the IEPs from younger years showed a pattern of decline from ES to MS to HS in the percentage of IEPs that commented on or
set goals pertaining to weaknesses in decoding. These findings suggest that basic skills deficits that persist into the upper
grade levels are not being sufficiently targeted for remediation, and help explain why older students frequently fail to resolve
their reading problems. 相似文献

Indigenous cultural contexts for STEM experiences: snow snakes’ impact on students and the community
Opportunities for American Indian youth to meaningfully engage in school-based science, technology, engineering, and mathematics (STEM) experiences have historically been inadequate. As a consequence, American Indian students perform lower on standardized assessments of science education than their peers. In this article we describe the emergence of meaning for students—as well as their community—resulting from Indigenous culturally-based STEM curriculum that used an American Indian tradition as a focal context. Specifically, the game of snow snakes (Gooneginebig in Ojibwe) afforded an opportunity for STEM and culturally-based resources to work in unison. A case study research design was used with the bounded case represented by the community associated with the snow snake project. The research question guiding this study was: What forms of culturally relevant meaning do students and the community form as a result of the snow snake game? Results indicate evidence of increased student and community engagement through culturally-based STEM experiences in the form of active participation and the rejuvenation of a traditional game. Implications are discussed for using culturally-based contexts for STEM learning. 相似文献

Educational technology research has passed through a number of stages, focusing, in turn, on the content to be learned, the format of instructional messages, and the interaction between computers and students. The field is now concerned with the study of learning in complete, complex, and interactive learning environments. These environments allow both the simulation of experiences that students might have in the real world and also the creation of compelling experiences that cannot normally be experienced directly. Learning environments also often allow students to communicate their own ideas with the use of a variety of symbol systems. These environments are also frequently inhabited by more than one person, making learning within them a social activity where learning is distributed among both people and artifacts. Finally, these learning environments are complex. Studying how they contribute to learning therefore requires research methods other than controlled experiments. This paper reviews research on learning environments to give both an historical perspective on educational technology research and a selective view of the current state of the discipline. It concludes by identifying implications for both practice and future research. 相似文献

In human infancy, 2 criteria for intentional communication are (a) persistence in and (b) elaboration of communication when initial attempts to communicate fail. Twenty-nine chimpanzees (Pan troglodytes) were presented with both desirable (a banana) and undesirable food (commercial primate chow). Three conditions were administered: (a) the banana was delivered (successful communication), (b) half of the banana was delivered (partially successful communication), and (c) the chow was delivered (failed communication). The chimpanzees exhibited persistence in and elaboration of their communication in every condition except when the banana was delivered. Thus, their communication was about a specific item, demonstrating that both intentionality and nonverbal reference are capacities shared by humans with our nearest living relatives, the great apes. 相似文献

Caption rate and text reduction are factors that appear to affect the comprehension of captions by people who are deaf or hard of hearing. These 2 factors are confounded in everyday captioning; rate (in words per minute) is slowed by text reduction. In this study, caption rate and text reduction were manipulated independently in 2 experiments to assess any differential effects and possible benefits for comprehension by deaf and hard-of-hearing adults. Volunteers for the study included adults with a range of reading levels, self-reported hearing status, and different communication and language preferences. Results indicate that caption rate (at 130, 180, 230 words per minute) and text reduction (at 84%, 92%, and 100% original text) have different effects for different adult users, depending on hearing status, age, and reading level. In particular, reading level emerges as a dominant factor: more proficient readers show better comprehension than poor readers and are better able to benefit from caption rate and, to some extent, text reduction modifications. 相似文献

New Caledonian crows make and use tools, and tool types vary over geographic landscapes. Social learning may explain the variation in tool design, but it is unknown to what degree social learning accounts for the maintenance of these designs. Indeed, little is known about the mechanisms these crows use to obtain information from others, despite the question’s importance in understanding whether tool behavior is transmitted via social, genetic, or environmental means. For social transmission to account for tool-type variation, copying must utilize a mechanism that is action specific (e.g., pushing left vs. right) as well as context specific (e.g., pushing a particular object vs. any object). To determine whether crows can copy a demonstrator’s actions as well as the contexts in which they occur, we conducted a diffusion experiment using a novel foraging task. We used a nontool task to eliminate any confounds introduced by individual differences in their prior tool experience. Two groups had demonstrators (trained in isolation on different options of a four-option task, including a two-action option) and one group did not. We found that crows socially learn about context: After observers see a demonstrator interact with the task, they are more likely to interact with the same parts of the task. In contrast, observers did not copy the demonstrator’s specific actions. Our results suggest it is unlikely that observing tool-making behavior transmits tool types. We suggest it is possible that tool types are transmitted when crows copy the physical form of the tools they encounter. 相似文献

The effects of method of reproduction, status of researcher, and personalization of signature on the initial rate of return of mail questionnaires were investigated, using a one-page combination cover letter and questionnaire mailed to 600 professors at the University of Maryland, College Park. The levels of each experimental variable were: Status — professor, graduate student; signature — hand signed in ink, mimeographed facsimile; reproduction — typed, photocopied, mimeographed.A response rate of 69% was obtained without using any follow-up procedures. Chi square analyses indicated no significant differences in the rate of returns for the levels of any of the experimental variables.It appears that initial return rate will not be significantly affected by using the most efficient, least expensive method available. 相似文献

Income levels and percentage change in 1971–1975 income were regressed on personal and institutional variables for husband and wife doctorates holding full-time academic positions. Results of the composite equation indicate a $1,254 premium associated with being male after controlling for the other variables. Composite results also indicate a negative relationship between income for one spouse and the perceived opportunities for employment of the other spouse. Separate equations for the spouses indicate that this result related only to the wives' perceived opportunities of their husbands' income. By eliminating individuals with education doctorates and substituting the husbands' weights for the wives', the $1,254 differential was partially eliminated. The remaining differential between husbands' and wives' income was due to the greater involvement of the males in consulting and administration, greater involvement of the women in education, and fewer number of years of full-time experience of the wives. Comparison of income changes in both the composite and separate equations indicate that the wives received an 8–9% greater income increase than their husbands. 相似文献
