Mathematics has always played an important role in the education of engineers and production managers. At the present time, the importance of mathematics has increased significantly and it is quite natural that in universities around the world engineering students are taking courses in mathematics which constitute, as a rule, a significant portion of their programme. At the same time, however, the mathematical education of the engineer is far from ideal and its improvement deserves the closest scrutiny. The present article deals with several general aspects of this problem. 相似文献

Conclusion Counseling in Arab schools in Israel is part and parcel of the whole Arab educationsystem. Like the system itself, counseling is also an object of many socio-politicalfactors which influence it negatively in such a status of affairs. However, unlikeother components of the system and due to its very nature, it is more susceptibleto these influences superimposed upon it. Its weakness is readily observable, morethan that of any other educational delivery service This weakness is due to itshigh level of susceptibility stemming from its nature as a reflector of both themacro and micro problems of education and society, to its being an object ofdifferent factors of cultural restraints since it is a super modern service plantedinto a traditional setting, to the lack of strong leadership and backing, and finally,at as due to the tact that at is at the cross-roads of conflicting political forces stemmingfrom the authonty's expectations on the one hand and from the community onthe other.Even though counseling and career guidance are found to be under varyingcultural and socio-political constraints in the Arab educational system in Israel,it is nonetheless a most meaningful educational service. Its meaningfulness isrecognized beyond its micro level of functioning (i e helping students in personalproblems, family issues and learning difficulties and/or guiding a student more orless successfully into a suitable career ). Its meaningfulness is notable also inthe following contributions.Firstly, it has a modernizing effect on the total educational system. It is aninnovation which Arab schools have had to cope with as they absorbed it. It createdpositive orientation towards innovations, especially those aiming at the well-beingof students. Secondly, counseling as a reflector of micro and macro problems hasuncovered those problems and brought them to the attention of students, teachers,authorities and communities. Thirdly, the introduction of counseling services intoArab schools opened a whole new path of vocational choice in that it familiarizedArab youth with a new area of vocations, namely the helping services in theirmodern sense. Finally, its introduction into the Arab educational system hassensitized students in particular, and the wider community an general, to look forprofessional help. Especially under conditions of cultural transition, this contributionis of special significance. Traditional ways of providing help to people haveeither vanished or become outdated and unsatisfactory. 相似文献

In this paper a conceptual model of instruction “the six mirrors of the classroom” used as a frame for teaching a learning
topic, the microorganisms are depicted. The paper consists of four sections: (a) the six mirrors of the classroom model (SMC);
(b) the SMC as implemented in the expository and cooperative modes of instruction in classrooms and results; (c) a “Journey
of Inquiry into the Wonderful World of Microorganisms” (JIWWM), developed according to the Science–Technology–Environment–Peace–Society
(STEPS) approach; and (d) teaching and learning the JIWWM, in ninth-grade classes, within the SMC model. The results show
that science topic can be taught in the frame of the mirrors of the classroom. When the instructional goals of the teachers
used the mirror “1, classroom organization” and mirror “6, pupils’ social behavior” and the third ring around the all six
mirrors cooperative skills were practiced, academic outcomes were achieved, and attitudes toward environmental preservation
and peace improved. The SMC model can serve as a valuable tool for teachers, since it can design their teaching and learning
settings in a more controlled environment, in terms of objectives, teachers’ and students’ social behaviors, and academic
outcomes. 相似文献

The present study focused on the epistemology of teachers’ practical knowledge by addressing the following research question: how do teachers attempt to reason about their practices and their practical knowledge? The results indicated that teachers supported their practical knowledge claims using the “practical argument”. Within this conceptual framework, they relied on contextual grounds that call for the fact that something should or should not be “done”, rather than something is “true” or “false”. Contextual grounds, then, were found to be backed up by two significant types of warrants: moral ethos, and “what works” notion. Depending on what kind warrants they used, teachers’ practical knowledge was interpreted to be based on two different epistemic statuses: “practicable” knowledge and “praxial” knowledge. 相似文献

Abstract Proponents of electronic mail systems (EMS) claim that they increase the productivity and efficiency of operations. Their use has mushroomed in the last five years in industrialized nations. The use of such systems in less developed countries is, however, practically nonexistent. This paper examines the barriers to their use in those countries. These barriers are divided into four categories: technical, economic, political, and social. Some strategies for dealing with those barriers are also presented. 相似文献

Bronfenbrenner’s (1979) ecological model proposes that events in higher order social ecosystems should influence human development through their impact on events in lower order social ecosystems. This proposition was tested with respect to ecological violence and the development of children’s aggression via analyses of 3 waves of data (1 wave yearly for 3 years) from 3 age cohorts (starting ages: 8, 11, and 14) representing three populations in the Middle East: Palestinians (N = 600), Israeli Jews (N = 451), and Israeli Arabs (N = 450). Results supported a hypothesized model in which ethnopolitical violence increases community, family, and school violence and children’s aggression. Findings are discussed with respect to ecological and observational learning perspectives on the development of aggressive behavior. 相似文献

Selective attention in processing of visual information by pigeons, trained on alternating sessions with two colors (red and
green) and two forms (a diamond and an X shape) differentially associated with a left—right key choice task, was examined.
A color and a form were presented together on probe trials during sessions in which, on other trials, only one of the dimensions,
color or form, was shown. The dimension in effect on the surrounding trials had no influence on choice when the information
provided by the two dimensions on probe trials was in conflict—color correct for one choice and form for the other. When both
color and form redundantly cued the correct choice, there was no increase in accuracy in comparison with that associated with
one dimension. Following separate training on the color and form discriminations, pigeons appeared to base their choices on
color on some trials, on form on other trials, but not on both simultaneously. These findings are discussed in terms of an
exemplar model of information processing. 相似文献
