This paper presents a two phase investigation of how Israeli students (grades 3 to 12) understand the concept of periodicity. Qualitative study, including classroom observations, as well as interviews with students and with teachers, was performed as a first phase. Quantitative study, including a survey of 895 eleventh grade students, was performed as a second phase. Students' errors in relating to non-periodic phenomena and to non-periodic function as periodic, as well as their period preferment, were revealed in both phases and were classified. The evidence supports the claim that students understand periodicity as a process. The students' errors and preferences are discussed with reference to two frameworks: (1) the understanding of periodicity as a process, (2) the Gestalt theory. 相似文献

Social stories were developed in order to support individuals with autism to better cope with social situations, an area of particular difficulty for this population. Despite its growing popularity, there is limited research evidence on the effectiveness of this approach. A review of research on social stories undertaken between 1994 and 2004 was carried out and the strengths and limitations of these studies discussed. Conclusions are drawn about ways in which future research might further develop the evidence base for the approach and about the confidence with which educational psychologists (EPs) can at present recommend this intervention. 相似文献

ResumenEn la primera parte la autora expone las características del estadio formal tal como lo presentan Inhelder y Piaget (1955) poniendo de manifiesto los puntos principales que diferencian la lógica del niño del estadio concreto y la del adolescente. Resitúa a continuación la noción de competencia en el marco más amplio de la de pensamiento. Finalmente, se discuten algunos de los problemas vinculados al estudio de la adolescencia considerada como un período de la vida: dificultades metodológicas (validación de los modelos y naturaleza de la evidencia empírica) y teóricas (definición del estadio teniendo en cuenta los cambios históricos). Gillièron hace una referencia a la dirección de las investigaciones actuales: definición de un quinto estadio, elaboración de modelos de performance,…para terminar con algunos comentarios sobre el egocentrismo de las distintas generaciones. 相似文献

好像每天的报纸都在报道天文学上的新发现:新的天体,新的物理过程,新的物质形式,等等.这种没完没了的发现哪天才到头呢?是否有一天天文学家会自信已经清点完了宇宙的全部资产? 相似文献

螺髻山具有得天独厚的自然景观和人文景观,但缺少一种宗教信仰方面的内容,使其局限于一次性旅游目的地。应当在螺髻山支格阿鲁文化遗迹基础上增建支格阿鲁文化展览馆、雕塑、壁画等丰富多样的支格阿鲁文化景观,进行支格阿鲁文化歌舞、影视开发利用,开展支格阿鲁文化体验式旅游活动,特别是创建支格阿鲁庙宇,把各地彝族人民最崇敬的英雄支格阿鲁神灵构建成为彝王祖灵,并为螺髻山主神,以供游客朝拜、许愿等活动。这样就能把螺髻山旅游景区打造成重复性旅游目的地,使游客多次来,甚至年年来朝拜或许愿与还愿,从而极大地提升其旅游效益。 相似文献

Several sets of data were employed in efforts to address the major concerns of this study. The first was a national survey of state directors of two‐year colleges. From them basic data regarding the distribution of funding for public two‐year college institutions on a state‐by‐state basis was obtained. It was found that 57% of funding nationally was derived from state legislatures, 17% from local or regional governments, 14% from tuition, and 10% from other sources. Also computed from the survey data was the distribution of full‐time enrollments by generic program. It was found that about half of the full‐time students were enrolled in occupational programs. Using selected national data, the cost per credit‐hour for 1979‐1980 full‐time students was computed to be $115 if 24 credit‐hours are considered a full‐time load, and $92 using 30 credit‐hours as a full‐time load. Also determined were the correlations between selected population data and certain public two‐year college demographics. Strong positive relationships were found between state populations, number of colleges in the state, and the magnitude of the states’ gross weights (fraction of total national full‐time enrollments found in that state). 相似文献

人类始祖神话一直是神话学界关注的热点,其叙事风格、内容与结构因族群而异,甚至同一族群内部也存有差异.神话是人们对超自然的崇拜以及对遥远历史记忆的表述,其真正反映的是人们的原型思维与原初生命认知.文章对彝、汉民族始祖传说的象征意义进行对比分析,以“求”始祖叙事的神话原型思维之“同”,“存”族群性认知源流之“异”,在“求同”与“存异”中彰显人类始祖神话的族群性表述. 相似文献

A brief account of developments in the experimental and theoretical investigations of Brownian motion is presented. Interestingly,
Einstein who did not like God’s game of playing dice for electrons in an atom himself put forward a theory of Brownian movement
allowing God to play the dice. The vital role played by his random walk model in the evolution of non-equilibrium statistical
mechanics and multitude of its applications is highlighted. Also included are the basics of Langevin’s theory for Brownian
motion.
Shama Sharma is currently working as lecturer at DAV College, Punjab. She is working on some problems in nonequilibrium statistical
mechanics.
Vishwamittar is professor in physics at Panjab University, Chandigarh and his present research activities are in nonequilibrium
statistical mechanics. He has written articles on teaching of physics, history and philosophy of physics. 相似文献

This study describes the design and use of a valid and reliable instrument to measure teacher candidates' attitudes and beliefs about mathematics and science and the teaching of those subjects. The instrument, Attitudes and Beliefs about the Nature of and the Teaching of Mathematics and Science, was developed for the Maryland Collaborative for Teacher Preparation (MCTP), a statewide, standards‐based project in the National Science Foundation's Collaborative in Excellence in Teaching Preparation (CETP) Program. We report on two applications of the instrument: (a) a contrast between MCTP teacher candidates' and non‐MCTP teacher candidates' attitudes and beliefs about mathematics and science as they initially encountered reform‐based instruction in their undergraduate courses, and (b) a landscaping of how the MCTP teacher candidates' attitudes toward and beliefs about mathematics and science evolved over a 2.5‐year period. In support of current reform in science and mathematics teacher education, we determined that over an extended period the MCTP teacher candidates' attitudes and beliefs moved substantively and significantly in the direction intended. However, we also found that the non‐MCTP teacher candidates in the same reform‐based courses did not mirror this improvement in their attitudes and beliefs about mathematics and science or the teaching of those subjects. © 2002 Wiley Periodicals, Inc.

Linear programming problems were presented, in a predominantly visual setting, to high school students who were not acquainted with any specific methods for solving such problems. The strategies developed by the students for coping with these problems were identified and classified. Visual strategies were developed more frequently than either algebraic or mixed ones. In many cases, these visual strategies were unsophisticated. Providing the students with a visual solution tool (a level curve of the target function) did not lead to significant changes. 相似文献
