Any educational service is provided through a large number of separated institutions and many decisions are necessarily taken by individual schools, and, indeed, by individual teachers. However, these day-to-day decisions are taken within a framework laid down elsewhere. Power and responsibility in an educational system relate chiefly to the extent and nature of the resources provided, the curriculum and teaching methods, the character and purpose of individual institutions and the internal organization of those institutions. Significant decisions may be taken at national, state, local authority and individual school levels. Cutting across such patterns are employer-employee relationships and agreements negotiated with trade unions. The system of governance and administration of schools in England is seen as a triangle of tension, the three points being central government, local government and individual schools. Reference is made to patterns of curriculum, examinations, supervision and finance, the English approach being compared with practices elsewhere. It is argued that within the constraints imposed by the controlling authority individual schools shouls possess a great deal of flexibility in making their own decisions, including questions of student-staff ratios, allocation of teachers and expenditure of finance. Power and responsibility should not be divorced, but related; this is the logical development of a system of distributed administration.
Zusammenfassung Jedes Bildungssystem besteht aus einer grossen Zahl separater Institutionen, und viele Entscheidungen müssen von den einzelnen Schulen und sogar den einzelnen Lehrern selbst getroffen werden. Der Rahmen für diese täglich notwendigen Entscheidungen wird jedoch an anderer Stelle festgelegt. Entscheidungsbefugnis und Verantwortung in einem Bildungssystem beziehen sich in der Hauptsache auf den Umfang und die Art der verfügbaren Mittel, auf Curricula und Lehrmethoden, den Charakter und Zweck der einzelnen Institutionen und ihre interne Organisation. Wichtige Entscheidungen können auf Staats-, Landes-, Bezirks- und Einzelschul-Ebene gefällt werden. Über diesen gazen Aufbau hinweg gehen Arbeitgeber-Arbeitnehmer-Beziehungen und Vereinbarungen mit Gewerkschaften. Das Leitungsund Verwaltungssystem für Schulen in England wird als ein Spannungsdreieck dargestellt, dessen drei Ecken die Zentralregierung, die örtlichen Behörden und die Schulen selbst bilden. Verschiedene englische Muster von Lehrplänen, Examen, Aufsich und Finanzen werden aufgezeigt und mit denen anderer Länder verglichen. Dabei wird betont, dass die einzelnen Schulen innerhalb der von der zuständigen Behörde gesetzten Grenzen ein grosses Mass von Entscheidungsfreiheit besitzen sollten, auch in Fragen wie Klassenstärke, Einsatz von Lehrern und Verwendung der Finanzmittel. Machtbefugnis und Verantwortung sollten nicht getrennt, sondern miteinander verbunden sein. Das ist die logische Entwicklung eines Systems aufgeteilter Verwaltung.

Résumé Tout service d'éducation est doté d'un grand nombre d'institutions distinctes, et, de ce fait, de nombreuses décisions sont prises individuellement par chacune des écoles, aussi bien que par chacun des enseignants. Quoiqu'il en soit, ces décisions prises au jour le jour, le sont dans les limites d'un cadre venant d'ailleurs. Dans un système d'éducation, pouvoir et responsabilité sont surtout liés à l'étendue et à la nature des ressources disponibles, du programme et des méthodes d'enseignement, du caractère et des objectifs de chaque institution, ainsi que de l'organisation interne de ces institutions. Les décisions importantes puevent être prises au niveau des autorités nationales, régionales ou locales, aussi bien qu'à celui de chacun des établissements scolaires. Les relations employeurs-employés, de même que les accords négociés avec les syndicats sont taillés sur le même modèle. En Angleterre, le système de gestion et d'administration des écoles apparait comme un triangle de tension dont les trois sommets sont constitués par le gouvernement central, le gouvernement local et les établissements scolaires eux-mêmes. Il est fait référence à d'autres modèles de programmes, d'examens, de contrôle et de finances, le système anglais étant comparé à ce qui ce fait ailleurs. Il est exposé que dans le cadre des contraintes imposées par l'autorité de contrôle, chaque école devrait posséder une grande marge de flexibilité pour prendre ses propres décisions, comprenant les questions des rapports d'associations d'élèves, les affectations des enseignants et les dépenses financières. Pouvoir et responsabilité ne devraient pas être séparés mais associés, tel est l'évolution logique d'une administration scolaire fonctionnant suivant un système de répartition.

To study sensitivity to radial location of an odor source, 20 human newborns, ranging from 16 to 130 hours of age, were presented with a small amount of ammonium hydroxide. The odor source was placed near the nose slightly to the left or right of midline, with its position randomized over repeated trails. Direction of headturn with respect to the odor location and diffuse motor activity were scored from the videotape recordings of the newborns' behavior. It was found that as a group, the newborns turned away from the odor source more frequently than they turned toward it. The tendency to turn away from the odor was stronger in infants who displayed less motor activity after the response. Newborns also exhibited a right bias in the direction of the head movements. It is concluded that a spatially appropriate avoidance response is present in the neonate and that the newborn is innately sensitive to the radial location of an odor.  相似文献

This paper presents two new techniques for use in personnel selection. One is a simple graphical technique which non-technical personnel can use to help in deciding how many minority applicants to admit to an institution. The other is a large-scale computer technique which an institution can use to increase personnel diversity on many variables (including culture) simultaneously. Both techniques appear to have major advantages over the particular technique this author advocated previously (1971). However, the new techniques are based on the same general view the author has expressed earlier (1971, 1973): that personnel selection questions concerning culture must be handled rationally—that is, by human judgment—rather than by mechanical formulas. Early sections of the paper summarize and defend that view.  相似文献

At 9 or 11 days of age, separate groups of Swiss-Webster mice received 12, 24, or 40 training trials to the goal opposite their first-trial choice in a shock-escape T-maze task. All groups were retested to the same goal for 25 trials 24 h following training, while maturation controls without prior exposure were trained to the goal opposite their first choice. All groups demonstrated increased escape proficiency during original training on two separate escape components: reaching the choice point and making the correct turn at the choice point. During retention testing, all groups at both ages exhibited better escape performance in terms of reaching the choice point than their maturation controls. However, when escape was measured in terms of choice, none of the groups trained at 9 days of age differed significantly from maturation controls when retested at 10 days of age. In contrast, retention of correct choice point turn varied directly with number of original training trials for mice trained at 11 days of age.  相似文献

Three experiments investigated the effects of magnitude and schedule of reinforcement and level of training in instrumental escape learning at a 24-h intertriai interval. In Experiment I, two magnitudes of reinforcement were factorially combined with two schedules of reinforcement (CRF and PRF). Under PRF, large reward produced greater resistance to extinction than did small reward, while the reverse was true under CRF. In Experiment II, two levels of acquisition training were factorially combined with three schedules of reinforcement (CRF, single-alternation, and nonalternated PRF). Patterned running was observed late in acquisition in the single-alternation extended-training condition. Resistance to extinction was greater for the nonalternated PRF condition than for the single-alternation condition following extended acquisition, and the reverse was true following limited acquisition. Experiment III confirmed the extinction findings of Experiment II. The results of all three experiments supported an analysis of escape learning at spaced trials in terms of Capaldi’s (1967) sequential theory.  相似文献

Third grade boys identified as being disruptive to on‐going classroom activities were grouped according to their teacher's ratings of their behaviour characteristics as unco‐operative (Type I), easily flustered (Type II), and unco‐operative and easily flustered (Type III). No significant differences in performance existed between types on individually administered tests of perception and psycholinguistic abilities. On group administered tests of academic achievement and intelligence, the uncooperative boys did significantly better than the other two types. It was also determined that the easily flustered boys did substantially better on individually administered measures of IQ. than they did on group administered measures. These findings suggest that teachers should avoid using group tests to evaluate disruptive boys they perceive as being easily flustered.  相似文献

In considering the evaluation of the preceptorship and residency programs, our faculty were asked to react to specific dimensions and aspects of the studies. Viewpoints about these data were submitted in formal critiques which will be summarized only briefly here. A number of the comments were in response to specific questions which had been posed; other were spontaneous from the faculty.  相似文献

The Minnesota Teacher Attitude Inventory (MTAI) and the Sixteen Personality Factors Questionnaire (16PF) were administered to 395 undergraduate teachers-in-training. The MTAI and the 16PF were compared using canonical analysis. They contained three related factors accounting for 41% of their total variance. It was concluded that teachers' attitudes toward their pupils are determined in large part by measurable personality traits.  相似文献
