The purpose of the study was to examine the relationship of classroom environment to attitudes toward science and achievement in science among tenth grade biology students. An attitude instrument was administered at three times during the school year to measure student attitudes toward science and the classroom environment. The classroom environment measures examined six areas: emotional climate of the science classroom, science curriculum, physical environment of the science classroom, science teacher, other students in the science classroom, and friends attitudes toward science. Student achievement in science was measured by teacher reported semester grades. The results of the study indicated: (1) student attitudes toward the classroom environment predicted between 56 to 61% of the variance in attitudes toward science, (2) student attitudes toward the classroom environment predicted between 5 to 14% of the variance in achievement in science, (3) student attitudes toward science and attitudes toward the classroom environment predicted between 8 and 18% of the variance in achievement in science. 相似文献

Major channels of communication are examined for two major functions: providing news of the ethnic community, and linking ethnics to the “mother country.” The four major channels are: interpersonal channels (friends and neighbors), radio, local metropolitan daily newspapers, and ethnic-language newspapers. Size of ethnic group is linked to channel preference, and greater ethnicity is related to a preference for ethnic media for both functions. Lower SES ethnics lend to rely more on interpersonal communication and ethnic media, while higher SES ethnics turn more to metro media and magazines. Channel preference as indicated by respondents is also linked to actual usage patterns. 相似文献

Two experimental procedures for positively modifying the attitudes of regular classroom children towards the handicapped were conducted. In both studies, curriculum and/or experiences with the handicapped were introduced to randomly selected groups of regular class elementary children. The curriculum consisted of literature, filmstrips, and lectures about handicapped children, while the experiences consisted of controlled integrational activities. The results indicated that the procedures were partially successful in modifying the attitudes of regular class children towards the handicapped. It was concluded that techniques must be developed systematically for achieving more positive attitudes in regular class children if “mainstreaming” is to become an effective educational concept. 相似文献

ABSTRACT The effectiveness of 8-week force-velocity optimised training was assessed in highly trained professional rugby league athletes. Players (age 24 ± 3 years; body mass 94.9 ± 21.6 kg; height 181.3 ± 6.0 cm) were strength-matched and assigned to a force-velocity optimised group (OP; n = 15) or a general strength-power group (GP; n = 14). Tests included 10-m, 20-m sprints, 3 repetition-maximum squat and squat jumps over five load conditions to ascertain vertical force-velocity relationship. ANCOVA revealed there was a group effect for force-velocity deficit (P < 0.001), with the OP two-fold greater than the GP group (OP pre: 51.13 ± 31.42%, post: 62.26 ± 31.45%, GP pre: 33.00 ± 19.60%, post: 31.14 ± 31.45%, P < 0.001). There were further group effects for 3RM squat (OP pre: 151.17 ± 22.95 kg, post: 162.17 ± 24.16 kg, GP pre: 156.43 ± 25.07 kg, post: 163.39 ± 25.39 kg, P < 0.001), peak power (OP pre: 3195 ± 949 W, post: 3552 ± 1033 W, GP pre: 3468 ± 911 W, post: 3591 ± 936 W, P < 0.001), and SJ (OP pre: 39.79 ± 7.80 cm, post: 42.69 ± 7.83 cm, GP pre: 40.44 ± 6.23 cm, post: 41.14 ± 5.66 cm, P < 0.001). Prescribing F-V deficit training is superior for improving physical performance within highly trained RL players. 相似文献

Active learning has attracted considerable attention in higher education in response to concerns about how and what students are learning. There are many different forms of active learning, yet most of them are classroom based. We propose an alternative to active learning in the classroom through active learning outside of the classroom in the form of student consulting projects. While the literature on student consulting has largely focused on projects to assist small business owners, this research demonstrates the potential for using student-consulting projects in the Production/Operations Management course. We use a case study to describe the use of a student-consulting project as an alternative to the other types of active learning described in the Operations Management education literature. 相似文献

The authors view the phenomenon of information overload as a result of a general failure in the business community to recognize the ways in which information processes add value to information. They present a conceptual model based on the broad information attributes of truth, guidance, accessibility, scarcity and weight, and apply the model to a number of information-oriented initiatives undertaken in Standard Life. The roles of both information providers and information users are discussed, with particular emphasis on the needs of managers and decision makers for high value-added, or ‘quality’, information. The authors argue the need to bridge a long-standing gap between information providers and users in their respectice views of what the role, competences and requirements of the other is in information terms. Their value-added information model provides a way for both parties to begin communicating in meaningful terms on these issues. 相似文献

Part of what has given higher education its remarkable stability in recent years has been its diversity. From the point of view of policy, there are three kinds of diversity in higher education: systemic, programmatic, and structural. Binary higher education systems, representing a form of systemic diversification, have evolved as a response to the massification of higher education. However, because of a number of factors, the perceived ideal remains the traditional university. The non‐university components of binary systems tend increasingly to resemble universities through processes of academic drift. To prevent these processes which in fact negate many of the intentions of planned diversification, social esteem and prestige must be built into all sectors which will then have an interest in preserving their individual identities. 相似文献
