Three-dimensional symmetry

The errors made when high-school students locate reflections in horizontal, vertical or slanting mirrors were examined. A questionnaire consisting of thirty-six perspective drawings, each portraying an upright transparent cube containing a two-sided mirror, was given to 394 Australian students from grades 7, 9 and 11. On a corner, an edge, or a face of each cube was drawn either a point or a straight-line segment. The task was to draw its image (reflection). Analysis of errors revealed a strong tendency towards horizontal or vertical sliding, suggesting that the edges of the cube act in much the same way as a horizontal-vertical background grid does in the two-dimensional case.     

Social perceptions and communicative interactions of handicapped and normal children in a preschool classroom

Ethological observational techniques and a sociometric test were used to investigate the social and communication interactions of five handicapped and four normal children in an open-informal preschool classroom. The observations revealed normal children primarily verbally interacted with normal children and the teacher. In contrast, the handicapped children interacted most frequently with teachers and less frequently with normal of handicapped children. Handicapped children were rarely verbal actors but rather receivers, with most of their communications coming from teachers rather than peers. Most of the positive play with and talk to sociometric choices obtained from both types of children indicated normal children were most frequently chosen while handicapped children were rejected or neutral. In addition, the less severe the communication handicap, the more apt the child was to be socially accepted. Spacing patterns of the children indicated that the normal children may serve as models who are not interacted with but who are observed by handicapped children.     

“Hispanic” children: Theoretical,empirical, and related policy issues

Not only are school-age ethnic and racial minority children one of the fastest growing segments of the U.S. population, they are also one of the most vulnerable. Hispanic children in particular are representative of the at-risk status of minority populations, displaying a portrait of unrealized social, educational, and employment success. This paper addresses the background and history of U.S. social and educational policies as they relate to the Hispanic student. Recent empirical findings are presented which support the following: (a) the bilingual character of Hispanic children is not a linguistic, cognitive, or educational liability and, in fact, should be employed to promote academic achievement; (b) the culture of the Hispanic family and child are better understood with regard to socialization variables and the potential differences they produce when directly compared to Anglo culture; and (c) educational strategies for Hispanic students that respect and integrate students' social, psychological, and linguistic attributes serve students effectively.     

Certifying effect and consumer effect: Some remarks on strategies employed by higher education institutions

The term certification, as used in discussions concerning higher education, is clarified and a distinction made between terminal awards which do have a genuine certifying effect in the sense of procuring admission to a profession and those which do not. Institutions wishing to increase the value of the certifying effect of their awards, seek to do this by stimulating applications for entry to their institution. The longer the queue at the gate the greater the prestige of the terminal award. The ability to influence the certifying effect of an award does not, however, lie with the teaching institutions alone; business, the employers and the professions can, and increasingly do, determine the relative value of awards and of different ways of preparing for the exercise of a particular profession. The case of the business schools in France is described to illustrate how teaching institutions once they are established seek to increase the certifying effect of the diplomas they award by actually reducing the number of graduates. The numerus clausus, as applied to medical schools, provides another example of the same phenomenon. Such strategies lead to what the author describes as consumer effect. Once admittance to a prestige institution has been gained, entry to a position of influence and possibly affluence, is more or less assured. Students in such institutions, in both capitalist and communist countries, have exploited this by persuading teaching staff to acquiesce in a reduction of the demands made by the course, though some directors of institutions have begun to respond by failing more students, seeking to re-establish positions surrendered in the days of student unrest and by these and other means seeking to reduce consumer effect. Teacher training colleges provide an interesting example of institutions having a low but certain certifying effect, producing a high consumer effect. The possibility of deriving a general theory from the proposition put forward in the article is discussed.This is an improved version of an article published earlier in French: Effet certifiant et effet clientèle.

Cognitive models and problem spaces in “purely random” situations

As part of a study on the natural interpretations of probability, experiments about elementary purely random situations (with dice or poker chips) were carried out using students of various backgrounds in the theory of probability. A prior study on cognitive models which analyzed the individual data of more than 600 subjects has shown that the most frequent model used is based on the following incorrect argument: the results to compare are equiprobable because it's a matter of chance; thus, random events are thought to be equiprobable by nature. The present paper is divided into two parts. In the first, the findings of a series of experiments are summarized. In the second, the following two hypotheses are tested: (1) Despite their incorrect model, subjects are able to find the correct response. (2) They are more likely to do so when the chance aspect of the situation has been masked. An experiment testing 87 students showed, as expected, that there is a way to induce the utilization of an appropriate cognitive model. However, the transfer of this model to a classical random situation is not as frequent as one might expect.     

The Effects of Storytelling and Story Reading on the Oral Language Complexity and Story Comprehension of Young Children

What began as a case study of intergenerational initiatives in university-based early childhood programs evolved into a comparative study of two different program implementation processes. Despite operating with the same goals, university partners, and resources, two early childhood centers pursued fundamentally different strategies for launching their intergenerational programs. One site followed what we call an explicit intervention with a set timeline and series of planned steps for finding, placing, and involving seniors in classroom activities. The other pursued what we call an emergent (or organic) strategy with no predetermined plan for finding senior volunteers and integrating them into classroom activities. Drawing on data collected from interviews with program staff and parents, and observations of intergenerational activities, this study serves to describe, compare, and contrast these alternative program initiation strategies. Both models are effective, but represent different approaches to valuing the contributions of older adults in the lives of young children.     

Conflict in Academic Departments: An Analysis of Disputes over Faculty Promotion and Tenure

Because the academic department is the foundational unit of U.S. universities, conflict in that setting is both theoretically and practically important. This analysis focuses on divisiveness in votes for promotion and tenure in departments at a large research university. The findings suggest that the departments most likely to experience very split voting patterns are those with larger instructional loads for faculty, low levels of internal curricular specialization, and soft disciplinary paradigms. The implications of these results for research and practice are discussed.     

The tasks of early childhood — Part I: The will to try

One of the important tasks of early childhood educators is to encourage young children to learn to strive and strive to learn. Caregivers are crucial in motivating children to persist at and take pleasure in learning tasks. Some children learn that their feelings are important and their actions are effective. They anticipate success. Their attitude is I can do it; When I try to do something, I can succeed. They are motivated to become competent. These youngsters are likely to become adults who find pleasure in doing something well, in working and achieving.

Much ado about nothing: Science and hermeneutics

Insofar as the basic concepts (in particular, meaning, interpretation, text) and theses of Martin Eger's hermeneutics of the sciences are intelligible they are not distinctive, and insofar as they are distinctive they are unintelligible and/or lack backup arguments. Ambiguity characterises much of the argument. James Cushing's elaboration of hermeneutics, using the history of quantum mechanics as an illustration of its supposed strengths, does nothing to rescue the position against the criticisms here levelled at Martin Eger's formulations of it.     

The applicability of democratic principles and the mission of the university

The university's mission of serving as a fortress for freedom of speech, inquiry, and criticism of established truths is inextricably connected with democracy. Such a mission can be pursued only in a climate of genuine political and academic freedom. Three other aspects of democracy in the university are discussed: equality of access, university governance, and the public utility of the university. It is argued that equal representation or one man one vote cannot be applied in university governance because it comes into conflict with the notion of competence—a conflict that cannot be resolved by taking votes. Interest groups inside and outside of the university cannot be allowed to interfere with the free pursuit of knowledge. The internal audit, that is, peer review (by, ultimately, the international community of scholars) has to take precedence over vertical review by government bureaucracy.     

Different aspects in designing mathematics education: Three examples from the Freudenthal Institute

Three teaching designs are offered. They were developed for 12 to 16 year old pupils taking into account their personal differences in terms of gender (in Making Up the Cube), culture (in Mecca), knowledge, and use of calculators in The integrating calculator. The designs concern the representation of three-dimensional objects in the plane, directions and great circles on the sphere, and exploration of the integrating calculator.     

Student learning work: Grounds for anin situ analysis

The ethnomethodological programme of studies of work is drawn on to provide a general framework within which we might develop ways to undertake thein situ analysis of the competencies which constitute student learning activities. The objective of such research is to describe the locally managed and temporally organised nature of student learning work. Emphasis is placed on the development of methods of investigation which will enable us to describe the whatness of the work from within the setting of that work's accomplishment. The twin conceptions of the visibility and sequential order of student activities are discussed in detail. The implications of this approach for the notion of student learning are also examined.     

Real-time simulation in computer-assisted instruction

Large scale computer-assisted instruction systems generally impose severe constraints upon the demands that individual users may make. Nevertheless, it is possible to overcome these problems and a program is described which teaches students how to fly a specific maneuver through real-time simulation of the flight of a student-controlled airplane. This is achieved in spite of the fact that the student is flying his plane through the use of a manually controlled analog input device. Both computational and educational implications are discussed.Contractual support for this work was provided in part by the Life Sciences Program Air Force Office of Scientific Research, Contract number F44620-70-C-0105.

The correlation between education and earnings - a comment

In this note, Blaug's article in Volume 1, No. 1, is criticised on the grounds that the economic interpretation of the correlation between education and earnings is based on a mistaken view about the nature of capital; and hence human capital theories are logically incoherent.     

Cultural pluralism and education: The Israeli case

Israeli society is often viewed as a Western democracy committed to values characteristic of this type of political system. Cultural pluralism is one of these values. The purpose of this paper is to examine the place of this value in the context of Israeli society, and in particular in its educational system. The paper raises serious doubts about the commitment of Israeli society to the value of cultural pluralism, especially in the educational domain. It is argued that the guiding ideology of the Israeli educational system is that of nation building, which aspires to cultivate a shared system of national values and common culture and inculcate them in its school children, thus leaving little room for the value of cultural pluralism. Furthermore, it is argued that the proposed integrative national and cultural agenda leaves no room for Israeli Palestinians, and favours the culture and traditions of Jews of European and American origin and is biased against the cultures and traditions of Jews of Asian and African origin.     

American college students' perceptions of counsellor approachability: Professional implications

The Repertory Grid technique was used to explore differences in the way in which freshers and postgraduate counselling students perceived the roles of counsellor and friend. Postgraduates viewed counsellors as more approachable than other students, while freshers viewed other students as more approachable than counsellors. The constructs identified by the students were content-analyzed to define approachability for each group. The perceptions held by students were used to address implications for the provision of outreach services, role-induction programmes, and the status of the counsellor as the professional.Department of Counseling and Educational Psychology, New Mexico State UniversityFor information contact Peggy Kaczmarek, Ph.D., New Mexico State University, Box 3CEP, Las Cruces, New Mexico 88003, United States.     

Frequency norms and structural analysis of algebra story problems into families,categories, and templates

The goal of this study was to develop a framework for classifying algebra story problems and to determine observed frequencies for each problem type. A total of 1097 algebra story problems were selected from ten standard algebra textbooks. These are divided into eight families based on the nature of the source formula involved; for example, nearly 300 problems were classified in the time rate family because they were based on the source formula, distance = rate x time or output = rate x time. Each family was divided into problem categories based on the general form of the story line; for example, the time rate family consisted of motion, current, and work categories. Each category was divided into templates based on the specific propositional structure of the problem; for example, there were a dozen templates for motion problems such as overtake, closure, round trip, etc. This article describes the procedure for generating families, categories, and templates and provides frequency counts for each observed template. Implications for fostering productive research and instruction are discussed.This research was supported by grant NIE-G-78-0162 from the National Institute of Education.

Winning the Battle,Losing the War: Bilingual Teachers and Post-Proposition 227

The implementation of Proposition 227 has created chaos, uncertainty, and a hostile environment for bilingual education teachers. This study describes the experiences of 20 bilingual education teachers in Southern California. In in-depth interviews, teachers speak out about the challenges, frustrations, fears, and the increasing animosity they face on a daily basis, and how they resist and contest the language enforcer role in various ways. Out of the chaos that has been created by Proposition 227, these bilingual teachers have emerged as the language civil rights activists of the new millennium.     

The non-education of Kurds: A Kurdish perspective

Educational provision in Kurdistan (embracing parts of Iran, Iraq, Syria and Turkey) violates most of the language-in-education requirements of international law. The same is true for Kurds in diaspora in most parts of the world. Linguistic and cultural genocide is attempted, with the tacit complicity of the West. The future of Kurdish education depends to a large extent on the political situation in the Middle East. Political solutions are needed before educational problems can be tackled. Within international law, a new interpretation by the UN Human Rights Committee of Article 27 in the International Convenant on Civil and Political Rights (UN 1986) might give grounds for hope for the future.

Zusammenfassung Bildungsmöglichkeiten in Kurdistan (einschließlich Teilen Irans, Iraks, Syriens und der Türkei) entsprechen nicht den internationalen Forderungen zur Sprachpolitik in der Bildung. Das gleiche gilt für Diaspora Kurden in den meisten Teilen der Welt. Mit stillschweigender Übereinkunft des Westen wird der linguistische und kulturelle Massenmord angestrebt. Die Zukunft der kurdischen Bildung hängt größtenteils von der politischen Situation im mittleren Osten ab. Bevor jedoch das Bildungsproblem gelöst werden kann, braucht man politische Lösungen. Innerhalb des internationalen Gesetzes könnte eine neue Auslegung des Artikel 27 im Internationalen Convent über zivile und politische Rechte (UN 1968) durch das Menschenrechtskommittee der Vereinten Nationen Hoffnung für die Zukunft bringen.

Resumen La educación prestada en Kurdistán (que comprende partes de Irán, Iraq, Siria y Turquía) viola la mayor parte de las exigencias que el derecho internacional establece en cuanto a la educación en la lengua correspondiente del individuo. Esto también rige para los kurdos, que se encuentran en la diáspora, en muchas partes del mundo. Con ello se intenta un genocidio cultural, con la complicidad tácita del mundo occidental. El futuro de la educación kurda depende en gran medida de la situación política de Oriente Medio. Se requieren soluciones políticas que permitan abordar los problemas de la educación, Dentro del derecho internacional, puede dar lugar a esperanzas una nueva interpretación que el Comité de Derechos Ilumanos de las Naciones Unidas hizo del artículo 27 en el Convenio Internacional de Derechos Civiles y Políticos (UN 1986).

Résumé Les formes d'enseignement dispensé au Kurdistan (partagé entre l'Iran, l'Iraq, la Syrie et al Turquie) violent la plupart des exigences envers les langues dans l'enseignement établies par le droit international. La même constatation est valable pour la diaspora kurde disséminée sur la quasi-totalité de la planète. Il ya a en fait tentative de génocide linguistique et culturel, avec la complicité tacite de l'Occident. L'avenir de l'éducation kurde dépendant dans une large mesure de la situation politique au Moyen-Orient, les problèmes pédagogiques ne peuvent être abordés que si la situation politique est résolue. Dans le adre du droit international, une nouvelle interprétation de l'article 27 de la Convention internationale des droits civils et politiques par le Comité des droits de l'hommes (ONU 1986) pourrait donner un nouvel espoir pour l'avenir.

An invasion in the classroom: influence of an ill-structured innovation on instructional and epistemological beliefs

In this article, the actual impact on students' instructional and epistemological beliefs of systematic attempts to implement a problembased, collaborative and technologicallyrich learning environment in regular, internationallyspread, secondary school classrooms is described. Although the literature suggests that learning environments do affect both categories of beliefs, empirical evidence is currently limited. To study the effects of learning environments, classroombased learning environments were redesigned in various respects. The change entailed the implementation of a problembased, collaborative and technologicallyrich environment to replace the more regular contentdriven, teachercentred and textbookbased environment. The implementation of the innovation was hypothesised to result in a change of both the instructional and epistemological beliefs of students. Moreover, these beliefs were expected to evolve in the direction of the assumptions underlying the innovative environment. A classical pretest and posttest study resulted in the confirmation of the first hypothesis. However, for the second hypothesis, the opposite was found: students' beliefs strengthened in a direction that contradicts the basic principles underlying the designed environment. The study highlights that a poor implementation of potentially powerful learning environments can result in unexpected and even undesirable side effects.
