A range of sources support science learning, including the formal education system, libraries, museums, nature and Science Centers, aquariums and zoos, botanical gardens and arboretums, television programs, film and video, newspapers, radio, books and magazines, the Internet, community and health organizations, environmental organizations, and conversations with friends and family. This study examined the impact of one single part of this infrastructure, a Science Center. This study asked two questions. First, who in Los Angeles (L.A.) has visited the California Science Center and what factors best describe those who have and those who have not visited? Second, does visiting the California Science Center impact public science understanding, attitudes, and behaviors and if so, in what ways? Two random telephone surveys of L.A. county adults 18 years of age and over (n = 832; n = 1,008) were conducted; one in 2000, shortly after the opening of the totally redesigned and rebuilt Science Center and one in 2009, roughly a decade after opening. Samples were drawn from five racially, ethnically, and socio‐economically diverse communities generally representative of greater L.A. Results suggest that the Science Center is having an important impact on the science literacy of greater L.A. More than half of residents have visited the Science Center since it opened in 1998 and self‐report data indicate that those who have visited believe that the Science Center strongly influenced their science and technology understanding, attitudes, and behaviors. Importantly, Science Center visitors are broadly representative of the general population of greater L.A. including individuals from all races and ethnicities, ages, education, and income levels with some of the strongest beliefs of impact expressed by minority and low‐income individuals. The use of a conceptual “marker” substantiates these conclusions and suggests that the impact of the Science Center might even be greater than indicated by the mostly self‐report data reported here. © 2010 Wiley Periodicals, Inc.

The purpose of this study was to investigate students' use of visual imagery while solving mathematical problems. Students with learning disabilities (LD), average achievers, and gifted students in sixth grade (N= 66) participated in this study. Students were assessed on measures of mathematical problem solving and visual‐spatial representation. Visual‐spatial representations were coded as either primarily schematic representations that encode the spatial relations described in the problem or primarily pictorial representations that encode persons, places, or things described in the problem. Results indicated that gifted students used significantly more visual‐spatial representations than the other two groups. Students with LD used significantly more pictorial representations than their peers. Successful mathematical problem solving was positively correlated with use of schematic representations; conversely, it was negatively correlated with use of pictorial representations. 相似文献

Quality reference service: A preliminary case study 总被引:1,自引:0,他引:1

A general reference department achieved a high score on the Wisconsin-Ohio Reference Evaluation Program. Intensive use of electronic resources, a good reference collection, good architecture, administrative support, and, most importantly, adequate time provided by the consultation model contributed, in this case, to high-quality service. 相似文献

Research findings suggest that most students who have foreign language learning problems have language-based difficulties
and, in particular, phonological processing problems. Authors of the present study examined pre- and posttest scores on native
language and foreign language aptitude tests of three groups of at-risk high school students enrolled in special, self-contained
sections of first-year Spanish. Two groups were instructed using a multisensory structured language (MSL) approach. One of
the groups was taught in both English and Spanish (MSL/ES), the other only in Spanish (MSL/S). The third group (NO-MSL) was
instructed using more traditional second language teaching methodologies. Significant gains were made by the MSL-ES group
on measures of native language phonology, vocabulary, and verbal memory and on a test of foreign language aptitude; the MSL/S
group made significant gains on the test of foreign language aptitude. No significant gains on the native language or foreign
language aptitude measures were made by the NO-MSL group. Implications for foreign language classroom instruction of at-risk
students are discussed. 相似文献

Students in psychology generally have difficulties to successfully accomplish mandatory courses in statistics. Group peer-tutoring is a pedagogical strategy to support them with a peer that has already successfully mastered the content of such a course. In order to specifically tailor group peer-tutoring to the needs of students and to sustain tutees’ participation, it is important to understand how they conceptualize tutoring. The aim of this study was to provide an empirical investigation of psychology students’ conceptualization regarding cross-year group peer-tutoring in statistics. A multivariate concept mapping analysis generated a relevant three-cluster structure (Tutoring setup, Tutor knowledge, interpersonal skills, and relational dynamics and Student role and commitment to the course) that underlies students’ cognitive structure regarding group peer-tutoring. The implications of the results for selecting and training peer-tutors are discussed. 相似文献

Many developments in profiling are taking place at present and a considerable number use a criterion‐referenced assessment model. This study reports the experiences of a local curriculum development project which has developed an English course and summative profile for lower‐attaining pupils. The way in which criterion‐referenced assessment was incorporated into the development of the profile is described, together with the results of a small‐scale survey of teachers’ views of the use of such a profile. Key issues for those developing such profiles in English and other subjects are identified. 相似文献

Abstract This article presents seven tests which were devised for measuring selected motor skills in fourth, fifth, and sixth grade boys and girls. An analysis of the data indicated that the tests were reliable for the population measured, and that age, height, and weight factors were not statistically significant in determining performance as measured by these tests. Performance standards were computed for each sex within each grade level. 相似文献

The Mechanics of Batting: Analysis of Ground Reaction Forces and Selected Lower Extremity Kinematics
Abstract The purpose of this study was to examine variations in ground reaction forces and selected lower extremity kinematics during the stride and swing phases of batting. High speed photography (100 fps) employing direct linear transformation methodology and a force plate were used to record three-dimensional kinematic and kinetic data for 7 female fast pitch softball batters. Mean vertical forces (Fz) of the right or rear foot increased to approximately 1 BW during the stride. Once the left or forward foot made contact with the ground after completion of the stride, right Fz forces decreased to .43 BW while left Fz forces rapidly increased to 1.6 BW at contact. The mean decrease in right Fz forces from peak force until contact was 55%, and the ratio of left to right Fz forces; at impact was 3.67:1. Right mediolateral forces (Fx) were exerted laterally, away from the batter, and were responsible for initiating movement of the body toward the pitched ball. As the left foot made contact with the ground at completion of the stride, left Fx forces were exerted laterally toward the pitched ball. The reaction to these forces retarded the batter's forward momentum, increased stability, and caused the left hip and knee to extend as contact approached. Right and left anteroposterior forces (Fy) acted in opposite directions (right foot pushing backward, left foot pushing forward), and were responsible for rotating the hips and upper body in a counterclockwise direction toward the pitched ball. Horizontal angular deceleration of both thighs just prior to contact was due, in part, to a decrease in these forces. These data may prove helpful when attempting to identify atypical batting patterns, and when considering improvements in shoe design. In the latter instance, force production and stability may be enhanced by aligning the cleats along the lines of action of the applied resultant shear forces. 相似文献
