This paper examines gender differences related to Information and Communication Technology (ICT) literacy using two valid and internally consistent measures with eighth grade students (N = 1,513) from Florida public schools. The results of t test statistical analyses, which examined only gender differences in demonstrated and perceived ICT skills, indicate significant differences in all areas in favor of females. Females had higher factor scores in perception measures for Frequency of Computer Use, Perceived ICT Skills, and Attitudes toward Computers. In addition, female students had significantly higher scores on all six sections from the Student Tool for Technology Literacy, a performance-based assessment. These results counter many empirical research studies that show males generally perform better with ICT skills and have overall better attitudes toward computers than their female counterparts. However, when adding predictors to the model and using multilevel modeling statistical methods, findings indicate that gender was no longer significant. These findings question the importance of the gender differences related to ICT skills that were found with previous statistical examinations. Using more advanced statistical methods to answer research questions pertaining to ICT skills is important in order to determine which factors have the greatest potential for intervention programs that focus on developing equitable ICT skills and career choices for all students. 相似文献

With the growing population of undergraduate students on our campus and an increased focus on their success, librarians at a large midwestern university were interested in the citation management styles of this university cohort. Our university library spends considerable resources each year to maintain and promote access to the robust bibliographic management tool RefWorks. A team of librarians wondered whether RefWorks might be used by undergraduate students with the same perceived enthusiasm that we have sensed in graduate students and faculty. More generally, we explored how undergraduate students were managing their citations, if and what kinds of tools they were using to ease the process of creating bibliographies, and their general workflow in incorporating citations into their academic work. 相似文献

Two librarians analyzed nursing students’ performance on an information literacy assignment to determine how they could change their instruction to better assist the students in comprehending the material. After identifying major areas of difficulty, including the use of search techniques, they revised both the instruction and the assignment, closing the loop by utilizing their assessment data. Next, they analyzed those results to evaluate the effectiveness of their changes and to make further improvements, thus demonstrating the iterative nature of instruction and assessment. The evidence-based instruction cycle of teaching, assessing, and revising should be repeated frequently to keep the assignment fresh and relevant. 相似文献

Abstract In this study, we examine the effect of exercise on the time and flow characteristics of the respiratory cycle profile at the point of volitional exercise termination. Eight males (mean age 29 years, s = 10; body mass 74 kg, s = 7; height 1.75 m, s = 0.04) undertook a cycle test to volitional exhaustion on a cycle ergometer, which allowed peak oxygen uptake ([Vdot]O2peak) to be measured (mean 51 ml · kg?1 · min?1, s = 7). At a later date, two sub-maximal tests to volitional exhaustion were completed in a random order at 76% (s = 6) and 86%[Vdot]O2peak (s = 7). As expected, the magnitude of the respiratory flow and time characteristics varied with the three exercise intensities, as did the point of exercise termination and terminal ventilation rates, which varied from 7 to 27 min and 112 to 132 litres · min?1 respectively. More importantly, however, at exercise termination some of the characteristics were similar, particularly the breathing frequency (at termination 49 breaths · min?1), the ratio between inspiration and total breath time (0.5), and the later occurrence of peak inspiratory flow (0.24 – 0.48 s). The coincident unity of these time and flow profile characteristics at exercise termination illustrates how the integration of timing and flow during breathing influence exercise capacity in non-elite athletes. 相似文献

We studied the effect of psyching-up on one-repetition maximum (1-RM) performance and salivary cortisol responses during the squat exercise. Ten men (age 21.6?±?1.4 years; mean?±?s) and ten women (age 22.4?±?2.8 years) with weight training experience of 4.5?±?2.0 years participated in this study. One-repetition maximum squats were performed on a Smith machine during each of two different intervention conditions that were counterbalanced and consisted of a free choice psych-up and a cognitive distraction. Saliva samples were obtained at the beginning of each test session and immediately after the final 1-RM attempt. No significant difference in 1-RM was identified between psyching-up (104?±?50?kg) and cognitive distraction (106?±?52?kg). Performing a 1-RM in the squat exercise significantly increased salivary cortisol concentrations during both conditions (P <?0.05). There was no significant difference in salivary cortisol responses between conditions. These results suggest that psyching-up does not increase 1-RM performance during the squat exercise in strength-trained individuals. 相似文献

Lesbian, gay, and bisexual (LGB) clients use counseling services at higher rates than their heterosexual counterparts, yet current training for counselors may be inadequate. In this online study, 234 graduate counselor education and counseling psychology students completed the Sexual Orientation Counselor Competency Scale ( Bidell, 2005 ) and provided information about their training in working with LGB clients. Participants viewed themselves as more competent on the Awareness and Knowledge subscales than on the Skills subscale. Increased level of training (doctoral vs. master's), number of LGB clients seen in practica, and attendance at LGB‐focused workshops and conferences were associated with increased competence. Implications for programmatic development are discussed. 相似文献

ABSTRACTIn order to create conditions for students’ meaningful and rigorous intellectual engagement in science classrooms, it is critically important to help science teachers learn which strategies and approaches can be used best to develop students’ scientific literacy. Better understanding how science teachers’ instructional practices relate to student achievement can provide teachers with beneficial information about how to best engage their students in meaningful science learning. To address this need, this study examined the instructional practices that 99 secondary biology teachers used in their classrooms and employed regression to determine which instructional practices are predictive of students’ science achievement. Results revealed that the secondary science teachers who had well-managed classroom environments and who provided opportunities for their students to engage in student-directed investigation-related experiences were more likely to have increased student outcomes, as determined by teachers’ value-added measures. These findings suggest that attending to both generic and subject-specific aspects of science teachers’ instructional practice is important for understanding the underlying mechanisms that result in more effective science instruction in secondary classrooms. Implications about the use of these observational measures within teacher evaluation systems are discussed. 相似文献
