Linear regression analysis is one of the most common techniques applied in developmental research, but only allows for an estimate of the average relations between the predictor(s) and the outcome. This study describes quantile regression, which provides estimates of the relations between the predictor(s) and outcome, but across multiple points of the outcome's distribution. Using data from the High School and Beyond and U.S. Sustained Effects Study databases, quantile regression is demonstrated and contrasted with linear regression when considering models with: (a) one continuous predictor, (b) one dichotomous predictor, (c) a continuous and a dichotomous predictor, and (d) a longitudinal application. Results from each example exhibited the differential inferences which may be drawn using linear or quantile regression. 相似文献

This study considers the role and nature of co-thought gestures when students process map-based mathematics tasks. These gestures are typically spontaneously produced silent gestures which do not accompany speech and are represented by small movements of the hands or arms often directed toward an artefact. The study analysed 43 students (aged 10–12 years) over a 3-year period as they solved map tasks that required spatial reasoning. The map tasks were representative of those typically found in mathematics classrooms for this age group and required route finding and coordinate knowledge. The results indicated that co-thought gestures were used to navigate the problem space and monitor movements within the spatial challenges of the respective map tasks. Gesturing was most influential when students encountered unfamiliar tasks or when they found the tasks spatially demanding. From a teaching and learning perspective, explicit co-thought gesturing highlights cognitive challenges students are experiencing since students tended to not use gesturing in tasks where the spatial demands were low. 相似文献

To contribute to the modest body of work examining the home literacy environment (HLE) and emergent literacy outcomes for children with disabilities, this study addressed two aims: (a) to determine the unique contributions of the HLE on print knowledge of preschool children with language impairment and (b) to identify whether specific child characteristics (oral language ability, print interest) moderated these relations. The sample consisted of 119 preschool children with language impairment. HLE was conceptualised as frequency of storybook reading and literacy teaching during book reading. Frequency of storybook reading was a unique predictor of print knowledge, which is consistent with research on children with typical language. Literacy teaching did not predict print knowledge, which diverges from research on children with typical language. No interactions between the HLE and child characteristics were significant, but language ability and print interest play a role in understanding individual differences in literacy development. 相似文献

Reading ability is comprised of several component processes. In particular, the connection between the visual and verbal systems has been demonstrated to play an important role in the reading process. The present study provides a review of the existing literature on the visual verbal connection as measured by two tasks, rapid serial naming and isolated (or discrete-trial) naming speed, as they relate to reading ability. For each identified study, a secondary data analysis was conducted using the provided correlations between serial naming, isolated naming, and reading. The same analysis was repeated for average population-level correlations among these constructs using meta-analytic weighting techniques. Results suggested that isolated naming acts as a suppressor variable in the relation of serial naming with reading, indicating that there exists at least one cognitive component of the serial naming task that is predictive of reading but is not shared with isolated naming speed. The effect has several implications for understanding the underlying cognitive components reading ability, which are discussed. 相似文献

The author discusses the different methods of reference assessment that have been tried in libraries over the years to help improve service, justify the existence of the service itself, train new staff, and counter declining statistics. 相似文献

A structured team approach in learning introductory COBOL programming was empirically assessed with a sample of 215 undergraduate business administration majors. For each assigned program, students in the experimental group read and critiqued team members’ program listings. COBOL proficiency was measured by a final examination testing knowledge of language rules, ability to read a program, and the ability to write a program. Analysis of multiple covariance was used to statistically adjust test scores for age and conditional reasoning scores. For the program writing variable, a significant difference favoring the experimental group was found. The language rules variable showed no significant difference, while the reading variable did not satisfy the required assumptions of the proposed statistical model. However, the experimental group showed higher mean scores for both of these variables. The findings provide empirical support for incorporating team activities into the programming learning process to more effectively develop student proficiency in writing COBOL programs. 相似文献

The authors assessed 3 of the currently available implicit association tests designed to measure attitudes toward persons with disabilities. The Revised Multiple Disability Implicit Association Test, the Implicit Association Test for Attitudes Toward Athletes With Disabilities, and the Disability Attitude Implicit Association Test were related to each other, demonstrating some consistency in measurement. They were mostly unrelated, however, to more traditional, explicit measures of attitudes toward persons with disabilities. In addition, although the implicit association tests were not related to socially desirable responding, the most psychometrically sound explicit measure (The Interaction With Disabled Persons Scale) was related to socially desirable responding. 相似文献

A basic factor of Chaim Perelman's rhetorical theory is the concept of the universal audience. Unfortunately, the concept of the universal audience, which follows in the tradition of Rousseau's general will and Kant's categorical imperative, is open to many of the same criticisms leveled against the general will and the categorical imperative. 相似文献
