Keyboarding compared with handwriting on a high-stakes writing assessment: Student choice of composing medium, raters’ perceptions, and text quality     

Carl  Scott B.  Jeb   《Assessing Writing》2008,13(1):4-25

This article examines the influence of keyboarding versus handwriting in a high-stakes writing assessment. Conclusions are based on data collected from a pilot project to move Old Dominion University's Exit Exam of Writing Proficiency from a handwritten format into a dual-option format (i.e., the students may choose to handwrite or keyboard the exam). This test case is used to demonstrate the complex implications for a writing assessment tool when universities aim to accommodate students’ various methods of physically creating a text. Discussion includes speculation about the format of the writing component on the SAT. It is argued that by analyzing the differences in high-stakes exams when students keyboard and when they handwrite, researchers can better understand how the material conditions for composing influence students and raters. It is concluded that if handwriting and keyboarding represent even slightly different composing skills and cognitive processes, then high-stakes writing assessments should aim to accommodate students by providing methods of textual production with which students are most comfortable, even as this accommodation produces new challenges for the creators and managers of large-scale writing assessments.  相似文献   

Teaching community-college students to follow the train of thought in expository texts     

Carl Spring  James Prager 《Reading and writing》1992,4(1):33-54

Community-college students in a one-semester remedial reading course were taught that main ideas in expository texts are located in sentences connected by rhetorical relations into trains of thought. After extensive practice with a variety of materials, they were compared to students in no-treatment and alternative-treatment control groups on (a) identifying main ideas while reading a test passage, and (b) recalling main ideas and supporting details two days later. The test passage differed in rhetorical structure from passages previously studied. Results indicated that the experimental group scored significantly higher than both control groups on main-idea identification. The experimental group also scored significantly higher than the alternative-treatment group on the free-recall of main ideas but not supporting details. Effect sizes were generally large. Information about the course is presented, and the theoretical rationale for its design is discussed. Implications for classroom instruction and for the reading comprehension curriculum are discussed.  相似文献

An Approach to Annual Assessment and Evaluation of University Faculty     

Carl J Huberty 《Journal of Personnel Evaluation in Education》2000,14(3):241-251

An approach used to determine some university faculty annual raises is described. Faculty assessment information is covered first. Tabular summaries made from this information are also described. Then the annual evaluation procedure carried out by a faculty review team and the department head are described. The method used to determine faculty raise allocations is presented. Difficulties and limitations of the approach are mentioned throughout.  相似文献   

Microliter-bioreactor array with buoyancy-driven stirring for human hematopoietic stem cell culture     

Camilla Luni  Hope C. Feldman  Michela Pozzobon  Paolo De Coppi  Carl D. Meinhart    Nicola Elvassore 《Biomicrofluidics》2010,4(3)

This work presents the development of an array of bioreactors where finely controlled stirring is provided at the microliter scale (100–300 μl). The microliter-bioreactor array is useful for performing protocol optimization in up to 96 parallel experiments of hematopoietic stem cell (HSC) cultures. Exploring a wide range of experimental conditions at the microliter scale minimizes cost and labor. Once the cell culture protocol is optimized, it can be applied to large-scale bioreactors for stem cell production at the clinical level. The controlled stirring inside the wells of a standard 96-well plate is provided by buoyancy-driven thermoconvection. The temperature and velocity fields within the culture volume are determined with numerical simulations. The numerical results are verified with experimental velocity measurements using microparticle image velocimetry (μPIV) and are used to define feasible experimental conditions for stem cell cultures. To test the bioreactor array’s functionality, human umbilical cord blood-derived CD34⁺ cells were cultured for 7 days at five different stirring conditions (0.24–0.58 μm∕s) in six repeated experiments. Cells were characterized in terms of proliferation, and flow cytometry measurements of viability and CD34 expression. The microliter-bioreactor array demonstrates its ability to support HSC cultures under stirred conditions without adversely affecting the cell behavior. Because of the highly controlled operative conditions, it can be used to explore culture conditions where the mass transport of endogenous and exogenous growth factors is selectively enhanced, and cell suspension provided. While the bioreactor array was developed for culturing HSCs, its application can be extended to other cell types.  相似文献
