Development of an Instrument to Measure Undergraduates’ Nanotechnology Awareness, Exposure, Motivation, and Knowledge 总被引:1,自引:1,他引:0

There are many educational interventions being implemented to address workforce issues in the field of nanotechnology. However,
there is no instrument to assess the impact of these interventions on student awareness of, exposure to, and motivation for
nanotechnology. To address this need, the Nanotechnology Awareness Instrument was conceptualized. This paper is a progress report of the instrument development process. Version 1 of the instrument was
administered to 335 first-year students majoring in food and agriculture fields in a pre–post fashion relative to a brief
exposure to nanotechnology in the classroom. Following item analysis of Version 1 responses, a revision of the instrument
was completed. Version 2 was administered to 1,426 first-year engineering students for the purpose of conducting item and
factor analyses. Results indicate that the Nanotechnology Awareness Instrument shows potential to provide valid information about student awareness of, exposure to, and motivation for nanotechnology.
The instrument is not a valid measure of nano-knowledge and this subscale was dropped from the final version of the instrument.
Implications include the use of the instrument to evaluate programs, interventions, or courses that attempt to increase student
awareness of nanotechnology. Further study is necessary to determine how the Nanotechnology Awareness Instrument functions as a pre–post measure. 相似文献

We propose a framework for evaluating the degree of authenticity of instructional tasks used within a teacher education program. First, we provide a defense for authenticity as an exemplary aspect of education. Second, we synthesize the theoretical literature on authenticity into conceptual codes. Using these codes, we build our authenticity framework around five criteria: the instructional task (1) is routinely performed by teachers, (2) involves students in a classroom, (3) promotes knowledge of practice, (4) involves self-reflection, and (5) serves formative purposes. We then discuss potential applications of our framework for the individual teacher educator and for program evaluation. 相似文献

Behavior rating scales aid in the identification of problem behaviors, as well as the development of interventions to reduce such behavior. Although scores on many behavior rating scales have been validated in the United States, there have been few such studies in other cultural contexts. In this study, the structural validity of scores on a Spanish translation of the six‐factor Child Behavior Scale (CBS) was assessed in a sample of 265 Peruvian preschool children who ranged from 2 to 6 years in age. Exploratory factor analysis yielded a four‐factor structure, and reliability estimates for scores on the four factors were adequate. The authors suggest replicating the study and examining the utility of CBS scores in predicting future problem behaviors in this population. © 2011 Wiley Periodicals, Inc. 相似文献

Adolescents struggle with setting and striving for goals that require sustained self‐discipline. Research on adults indicates that goal commitment is enhanced by mental contrasting (MC), a strategy involving the cognitive elaboration of a desired future with relevant obstacles of present reality. Implementation intentions (II), which identify the action one will take when a goal‐relevant opportunity arises, represent a strategy shown to increase goal attainment when commitment is high. This study tests the effect of mental contrasting combined with implementation intentions (MCII) on successful goal implementation in adolescents. Sixty‐six 2nd‐year high school students preparing to take a high‐stakes exam in the fall of their third year were randomly assigned to complete either a 30‐minute written mental contrasting with implementation intentions intervention or a placebo control writing exercise. Students in the intervention condition completed more than 60% more practice questions than did students in the control condition. These findings point to the utility of directly teaching to adolescents mental contrasting with implementation intentions as a self‐regulatory strategy of successful goal pursuit. 相似文献

WHAT PISA TELLS US ABOUT THE QUALITY AND INEQUALITY OF JAPANESE EDUCATION IN MATHEMATICS AND SCIENCE
Researchers, policy officials, and the wider public in Japan and abroad often hold different views about the quality of Japanese
education. Whereas Western researchers are attracted by the academic performance of Japanese students in international assessment
studies, Japanese university professors launched a public debate in 1999 about declining achievement. Both advocates and detractors,
however, assume that students perform equally well or bad, teachers do not differ in their methods, and students are treated
similarly across schools. This study explored the validity of the mutually opposing views about the quality of Japanese education
and addressed the issue of unequal educational opportunities, which has not been investigated based on representative, large-scale
datasets. According to the Programme for International Student Assessment (PISA) studies, Japanese students performed well
but a decline is visible between 2003 and 2006 for mathematics. The PISA studies also indicate that an achievement gap exists
in Japan and that tracking leads to differential school experiences. 相似文献

Architects who use universal design create accessible spaces for diverse users. Jeanne Higbee and Heidi Barajas describe how that model can be adapted to the design of effective learning environments for a wide range of students. 相似文献

The players' ability to achieve the greatest distance in kicking is determined by their efficiency in transferring kinetic energy from the body to the ball. The purpose of this study was to compare the kinetics and kinematics of the plant leg position between male and female collegiate soccer players during instep kicking. Twenty-three soccer players (11 males and 12 females) were filmed in both the sagittal and posterior views while performing a maximal instep kick. Plant leg kinetic data were also collected using an AMTI 1000 force platform. There were no significant differences between the sexes in plant leg position, but females had significantly greater trunk lean, plant leg angle, and medial-lateral ground reaction force than the males. Males showed higher vertical ground reaction forces at ball contact, but there were no significant differences in ball speed at take-off between the sexes. Ball speed at take-off was inversely related to peak anterior-posterior ground reaction force (-0.65). The anatomical differences between the sexes were reflected in greater trunk lean and lower leg angle in the females. 相似文献
