The current study aimed to assess the validity and test–retest reliability of a linear position transducer when compared to a force plate through a counter-movement jump in female participants. Twenty-seven female recreational athletes (19 ± 2 years) performed three counter-movement jumps simultaneously using the linear position transducer and force plate for validity. In addition, 11 elite female athletes (23 ± 6 years) performed 3 counter-movement jumps with the linear position transducer on three separate days for test–retest reliability. Pearson correlations for jump height between the devices were at a high level (r = .90), with the linear position transducer overestimating jump height by 7.0 ± 2.8 cm. The reliability measured by the linear position transducer resulted in a mean intraclass correlation of .70 for jump height, .90 for peak velocity, and .91 for mean velocity. The linear position transducer was reliable for measuring counter-movement jumps in elite female athletes; however, caution should be taken for one-off jump measures as it may over-estimate jump height. 相似文献

Structuring job interviews is a method of decreasing bias and increasing the predictive validity of job performance, but research suggests that applicants can react negatively to structure (Chapman & Zweig, 2005) and that negative attitudes about selection tools can predict performance (Hausknecht, Day, & Thomas, 2004). The current exploratory study investigates how structuring the job interview in conjunction with priming the ethnicity and sex of the applicant, and in some conditions providing an explanation of the structure, affected post‐interview cognitive ability performance. Three levels of structure were randomly assigned. Those who experienced a structured interview without an explanation of its purpose scored lower than those who experienced an unstructured interview, but those who experienced a structured interview with an explanation of its purpose did not score lower than those who experienced an unstructured interview. Scores differed for females and Hispanics depending on the structure condition, but not in the same manner. Implications for recruitment, selection, and performance management are discussed. 相似文献

This case study of a science lesson, on the topic thermal expansion, examines the language demands on students from an integrated science and language perspective. The data were generated during a sequence of 9 lessons on the topic of ‘States of Matter’ in a Grade 7 classroom (12–13 years old students). We identify the language demands by comparing students' writings with the scientific account of expansion that the teacher intended the students to learn. The comparison involved both content analysis and lexicogrammatical (LG) analysis. The framework of Systemic Functional Linguistics was adopted for the LG analysis. Our analysis reveals differences in the meaning and the way LG resources were employed between the students' writings and the scientific account. From these differences, we found the notion of condition-of-use for LG resources to be a significant aspect of the language that students need to appropriate in order to employ the language of school science appropriately. This notion potentially provides a means by which teachers could concurrently address the conceptual and representational demands of science learning. Finally, we reflect on how the complementary use of content analysis and LG analysis provides a way for integrating the science and language perspectives in order to understand the demands of learning science through language. 相似文献

Ten pupils with moderate learning difficulties worked on a series of mathematics related activities while visiting a school providing a whole range of multi-media. The investigation suggests that IV has a particular contribution to make in meeting special educational needs. In addition to specific benefits in the teaching and learning of mathematics, the technology proved to be a facilitator in the areas of geography and life skills. There was also some evidence to suggest that IV can help to raise self-esteem, provide equal opportunities and support collaborative learning. Sense of ownership, language development and motivational characteristics, together with the promotion of attention and the accompanying benefit for teachers of the reduction of anxiety over discipline, are other factors suggesting the usefulness of the medium in this context. 相似文献

The study examined the ability of deaf and hearing students at the college and middle school levels to discern and apply knowledge of printed word morphology. There were 70 deaf and 58 hearing participants. A two-part paper-and-pencil test of morphological knowledge examined subjects' ability to (a) perceive segmentation of morphemes within printed words and (b) recognize meanings associated with various printed morphemes. The hearing college students performed best on every dependent measure of the two-part test. The deaf college students scored significantly lower than the hearing college students but similarly to the hearing middle school students. Deaf middle school students consistently scored the lowest on both parts of the test. While all students' performance declined as the difficulty of the morphemic content increased within both tasks, the decline was greatest among middle school deaf students. Although segmentation and semantic analysis skills necessary to morphographic decoding were apparent in the deaf students, their mastery levels fell significantly below those of the hearing subjects. 相似文献

Objectives of a project-oriented mechanical engineering course, Engineering Design, were achieved through a design project, where students designed, built and demonstrated an extreme version of a basic Theo Jansen device. Through this project, junior students in the University of Louisiana fully developed the capability of applying mathematic and kinematic knowledge in the analysis and design of mechanisms. Students also developed oral and written communication skills, which would be used in design environments, through the presentation of results in both oral and written forms. An assessment of the design project indicated that effective teaching and learning spread through the semester, with the junior students acting as project managers and experiencing design practices. An example of a student-designed Theo Jansen device is presented in this paper to show the study results achieved by the students. 相似文献

To understand the experiences and views of childbearing women in the United States and trends over time, Childbirth Connection carried out the third national Listening to Mothers survey among 2,400 women who gave birth in U.S. hospitals to a single baby from mid-2011 to mid-2012 and could participate in English. A follow-up survey directed to the same participants explored postpartum experiences, in depth and well into the second year after birth; views about maternity care; and some additional pregnancy and birth items. Harris Interactive conducted the surveys using a validated methodology that includes data weighting to ensure that results closely reflect the target population. The follow-up survey was reported in Listening to Mothers III: New Mothers Speak Out. 相似文献

This study investigates the dialogic processes involved in how teachers talk about their students and what consequences their ways of talking (i.e., “narratives”) may have for their guidance. We take a sociocultural perspective on learning as transformation of students’ subjectivity. Teaching, as a process of guiding and facilitating learning, cannot be effective if the teacher does not actively seek how the student perceives and understands reality. We borrow and adapt from Bakhtin (1999) four narrative ways of talking about others: objectivizing, subjectivizing, problematizing and finalizing. The presence of these narratives in web discussion postings of our pre-service teachers about the Latino children they worked with in a community center are analyzed. We then compare their ways of talking about children with print- and web-based discussions about children made by in-service teachers, model teachers and our pre-service teachers in a school-based practicum. Using mixed quantitative and qualitative methodologies, we found an overwhelming predominance of objectivizing and finalizing in our pre-service teachers’ narratives about the children with whom they work that seems to define a certain pedagogical regime that we call here “teaching imaginary children/students.” This “way of talking” about children seems to be characterized by unchecked speculations guiding instruction that are not tested by finding out from the children themselves how they understand the instruction and the world. These speculations, in turn, can lead to a dogmatic approach towards children. 相似文献

Not only are school-age ethnic and racial minority children one of the fastest growing segments of the U.S. population, they are also one of the most vulnerable. Hispanic children in particular are representative of the at-risk status of minority populations, displaying a portrait of unrealized social, educational, and employment success. This paper addresses the background and history of U.S. social and educational policies as they relate to the Hispanic student. Recent empirical findings are presented which support the following: (a) the bilingual character of Hispanic children is not a linguistic, cognitive, or educational liability and, in fact, should be employed to promote academic achievement; (b) the culture of the Hispanic family and child are better understood with regard to socialization variables and the potential differences they produce when directly compared to Anglo culture; and (c) educational strategies for Hispanic students that respect and integrate students' social, psychological, and linguistic attributes serve students effectively. 相似文献
