Simulated data were used to demonstrate that groups formed by imposing cut-points based on either discrepancy or low-achievement definitions of learning disabilities (LD) are unstable over time. Similar problems were demonstrated in longitudinal data from the Connecticut Longitudinal Study, where 39% of the children designated as having LD in Grade 3 changed group placement with repeated testing in Grade 5. These results show that the practice of subdividing a normal distribution with arbitrary cut-points leads to instability in group membership. Approaches to the identification of children as having LD based solely on individual test scores not linked to specific behavioral criteria lead to invalid decisions about individual children. Low-achievement definitions are not a viable alternative to IQ-discrepancy definitions in the absence of other criteria, such as the traditional exclusions and response to quality intervention. If we accept the premise of multiple classes of low achievers, then we must develop identification systems that are valid and abandon systems whose only merits are their historical precedence and convenience. 相似文献

Courses: Argumentation, Public Speaking, Political CommunicationObjectives: After completing this unit activity, students should be able to (1) demonstrate comprehension of Burke’s (1941) concept of terministic screens; (2) apply the concept of terministic screens to write a brief political autobiography of themselves that analyzes the history of and framework for their own political beliefs; and (3) synthesize the concepts of terministic screens and informational diversity to frame readings and discussions of peers’ autobiographies, as well as future class discussions of controversial topics. 相似文献

In Brazil, a federal law ensures that all students with disabilities are entitled to enrollment in higher education institutions. Higher courses in human anatomy stand out for their complexity in both theoretical and practical contents. Therefore, adaptation is required to accommodate students with special educational needs. This study aimed to describe the experience of a Support Teacher in the development of inclusive pedagogical practices for the discipline of Human Anatomy offered in the physiotherapy course for a student with low vision and blindness. The challenges and learning difficulties faced by a visually impaired student are reported. Qualitative analysis was performed by interviewing a student with low vision and blindness and a Support Teacher. The audio recordings were transcribed, categorized, and analyzed using content analysis. The Support Teacher created schematics and drawings of anatomical structures, reviewed theoretical and practical contents, developed adaptations of the examinations, and applied palpatory anatomy to facilitate the student’s learning process. The findings illustrate that the student faced the greatest difficulty in dealing with the emotional aspects, due to the inability to visualize the anatomical details in human cadavers. Thus, the presence of a Support Teacher was fundamental to ensure that the student could learn the content and overcome this limitation. In conclusion, personalized adaptation, commitment, and collaborative work between the Support Teacher and students with low vision and blindness improve their learning conditions. 相似文献

Previous research clearly demonstrates the positive impacts of using verbal immediacy in the college classroom. This paper explores the issue of training university instructors to increase their verbal immediacy use while teaching. First, a brief literature review recaps recent verbal immediacy studies and the reasons training could be valuable. Next, the training method is outlined and results reveal how university teachers were successfully trained to use significantly more verbal immediacy in their classrooms, compared to a control group of teachers who were not trained. A discussion concludes with the implications for improving college teaching. 相似文献

Professional leaders have identified clear roles for social workers involved in advance care planning (ACP), a facilitated process whereby individuals identify their preferences for future medical care; yet information about effective teaching practices in this area is scant. This study reports on the experiences of 14 social workers who participated in a nationally recognized, evidence-based ACP facilitator certification program. Researchers first analyzed data consisting of participants’ in-depth reflective writings using an inductive thematic analysis process. Identified themes were subsequently grouped into three categories to characterize the “novice” experience of participants: theoretical knowledge, skill development, and self-reflection. Findings underscore the importance of ACP training in social work education and the need for teachers to help learners better understand the process of professional skill development. 相似文献

We present a low cost microfluidic chip integrating 3D micro-chambers for the capture and the
analysis of cells. This device has a simple design and a small footprint. It allows the
implementation of standard biological protocols in a chip format with low volume consumption. The
manufacturing process relies on hot-embossing of cyclo olefin copolymer, allowing the development of
a low cost and robust device. A 3D design of microchannels was used to induce high flow velocity
contrasts in the device and provide a selective immobilization. In narrow distribution channels, the
liquid velocity induces a shear stress that overcomes adhesion forces and prevents cell
immobilization or clogging. In large 3D chambers, the liquid velocity drops down below the threshold
for cell attachment. The devices can be operated in a large range of input pressures and can even be
handled manually using simple syringe or micropipette. Even at high flow injection rates, the 3D
structures protect the captured cell from shear stress. To validate the performances of our device,
we implemented immuno-fluorescence labeling and Fluorescence in Situ Hybridization
(FISH) analysis on cancer cell lines and on a patient pleural effusion sample. FISH is a Food and
Drug Administration approved cancer diagnostic technique that provides quantitative information
about gene and chromosome aberration at the single cell level. It is usually considered as a long
and fastidious test in medical diagnosis. This process can be easily implanted in our platform, and
high resolution fluorescence imaging can be performed with reduced time and computer intensiveness.
These results demonstrate the potential of this chip as a low cost, robust, and versatile tool
adapted to complex and demanding protocols for medical diagnosis. 相似文献

Beyond the Screen: Narrative Mapping as a Tool for Evaluating a Mixed-Reality Science Museum Exhibit
Karla Saari Kitalong Jane E. Moody PhD Rebecca Helminen Middlebrook Gary Saldana Ancheta 《Technical Communication Quarterly》2013,22(2):142-165
This article describes the authors' work as formative evaluators of a mixed-reality science museum installation, Journey with Sea Creatures. Looking beyond the focal point of the screen to the spatial and temporal surroundings of the exhibit, the authors employed a technique they call retrospective narrative mapping in conjunction with sustained on-site observations, follow-up interviews with museum visitors, and the development of personas to better understand the user experience in multimodal informal learning environments. 相似文献

This study identifies factors associated with freshmen retention rates at a mid‐size private university. A key finding from our analysis is that roommates' academic efforts, residing on an honours floor and membership in co‐curricular groups increase retention. We also confirm many standard results in the literature regarding the impact on retention rates, such as student motivation and ability, and financial aid. We show that a timely housing application, closer proximity to home, a higher number of schools on a student's Free Application for Federal Student Aid and peer effects impact freshman retention. Our results suggest that a more sophisticated dormroom assignment algorithm matching students' abilities and interests could be considered to increase freshman retention rates among private institutions. 相似文献
