Are children competent producing anatomy cross-sections? To answer this question, we carried out a case study research aimed at testing graphic production skills in anatomy of nutrition. The graphics produced by 118 children in the final year of primary education were analysed. The children had to draw a diagram of a human cross section, integrating knowledge of anatomy acquired from longitudinal sections. The results show that they have very limited skills in producing these graphics judging by the dimensions (scale, shape, organs represented and its organization inside the section) and their conception of human anatomy at thoracic level (location of the organs, elements in the spaces between them and connections between organs). The results also indicate that the only exposure to cross-sections in daily life is not enough by itself to draw them correctly, so this type of graphic production should be addressed from the earliest stages of education, since it contributes to the development of visual literacy, and this is a crucial skill when it comes to learning science concepts and developing scientific literacy. 相似文献
ITERS (Infant and Toddler Environment Rating Scale), ECERS (Early Childhood Environment Rating Scale) and SACERS (School Age Care Environment Rating Scale) are used to measure process quality. The psychometric characteristics of the three scales are established, and high reliability and adequate validity are observed. The global quality process for the classrooms under study is less than good; process quality based on the direct interaction of adults with children in the classroom is better when compared with quality related to the experiences that children have with learning materials, equipment and space. The associations between child development outcomes and childcare quality are examined. Vocabulary, social development and adaptive behaviour show a strong and positive association with ECERS. Hierarchical regression analyses show that preschool quality has a significant and persistent effect in the variation of child outcomes (5%). These effects are maintained three years later, when children are in primary school (8%). 相似文献
This project tries to deal with all the difficulties adults of a low educational level are liable to cope with when they reed perspective drawings of an object, the real object being there or not. The subjects have to compare perspective drawings with a “model drawing” or a “model object”. The results show the difficulties of both exercices are related to people’s space conceptualisation: reading spatial depth relationships in drawings, coordination view-points, mental rotation. These observations gives us the possibility to give some didactic suggestions. 相似文献
Rubrics have attained considerable importance in the authentic and sustainable assessment paradigm; nevertheless, few studies have examined their contribution to validity, especially outside the domain of educational studies. This empirical study used a quantitative approach to analyse the validity of a rubrics-based performance assessment. Raters evaluated the performance of 84 first-year university students producing service-learning projects for the Conservation–Restoration and Design degrees. The study data comprised the 9240 scores given by two teachers and three student tutors, who assessed the students’ projects on three occasions during the semester. Factor analyses confirmed that the students attained the expected learning outcomes and made significant learning progress. This learning progress was also corroborated by analyses of variance. The attainment of the learning goals and the evidence of learning progress demonstrated the validity of the inferences drawn from the assessment system. In addition, the results highlighted the need to consider rubrics as a first-order teaching resource and not only as a scoring tool. 相似文献
Cooperative learning is an important methodological strategy to develop students’ general competencies. In this paper, we show an educational innovation experience of cooperative learning developed as part of the ‘Educational contexts and processes’ subject of the Speciality in Technology and Industrial Processes of the Master’s Degree in Secondary Education Teaching at the University of Valencia, during the 2011–12 academic year. The innovation experience becomes ‘meta-experience’ since it allows students to reflect on their own knowledge in building the learning process. The overall objective of this experience is to develop attitudes and skills for cooperative learning in future secondary education teachers. To this end, we designed the activity ‘Short Film’ that employs cooperative learning as a methodological strategy to foster learning and media literacy. The experience gave students the opportunity to reflect, discuss and be involved in their learning process. Furthermore, the academic results were excellent and students valued the educational innovation in a positive way. 相似文献
It is expected that children increasingly learn to identify errors throughout their schooling process and even before it. As a further step, however, some scholars have suggested how a culture of error should be implemented in the classroom for the student to be able not only to locate errors but also, and above all, to learn from them. Yet the various proposals aimed at generating a culture of error in the classroom keep regarding error as all those responses and reactions that are not considered as true or correct in each specific case, thereby not realizing that many of these alleged errors are really anomalies with very different characteristics and consequences despite their seeming resemblance. In this paper, I rely on Ludwig Wittgenstein’s On Certainty to clarify the difference between errors and anomalies. Subsequently, I provide guidelines that may be adapted by each teacher to her students’ needs and development level in order to foster a culture of error that begins by distinguishing error from anomaly, which constitutes a practical as well as conceptual necessity particularly in Child and Primary Education, as it is just then when anomalies most frequently arise in the form of questions and answers. 相似文献
Zusammenfassung In diesem Artikel mochten wir einerseits die umstrittene Langewel‐lentheorie beschreiben, die in wirtschaftlichen Kreisen vom Scheinwerfer des Interesses beleuchtet wird. Dabei schenken wir der ebenso umstrittenen Erklärungstheorie Schumpe‐ters fur diese Langewelle unsere besondere Aufmerksamkeit.
Wir legen uns anderseits die Frage vor, ob ein Zusammenhang besteht zwischen dieser Langewelle und den Möglichkeiten, über die man während einer festgesetzten Periode verfügt, um gewisse Innovationen bei der Lehrerbildung einzuführen, zu realisieren und besonders die Kosten dafür zu tragen.
Wir versuchen, unsere Annahme, ‘dass tatsächlich ein solcher Zusammenhang besteht’, zu erläutern mit einer Beschreibung einiger Auffallenden Gegebenheiten der Evolution der (west) deutschen Lehrerbildungen gegen den Hintergrund der Langewelle.
In weiteren Untersuchungen werden wir versuchen, diese provisorisch verfasste aber verantwortbare Annahme zu überprüfen und nachzuweisen. Im Interesse der Sache wäre es zu begrüssen, wenn auch andere Forscher die Folgen fur die Integration der Lehrerbildungen studieren mochten. Wir glauben, eine solche Untersuchung könne gesellschaftlich relevant sein. 相似文献
Research Findings: Two longitudinal studies are reported examining the effects of full-time day care in Mapuche and non-Mapuche families in Chile. First, the Magellan-Leiden Childcare Study (MLCS) used a sample of 95 mothers with children younger than 1 year old (n = 36 in day care). Second, we partially cross-validated our results in a large and representative sample of 10,723 mothers and their children from the Chilean Encuesta Longitudinal de la Primera Infancia (Early Childhood Longitudinal Survey). In both studies, the quality of care for children provided at home was measured with the Home Observation for Measurement of the Environment. In the MLCS study, additional indicators of the mother–child relationship were measured. Day care was not negatively associated with the mother–child relationship and maternal sensitivity, compared to maternal care, or with the quality of the home environment. Positive changes in attachment security were found in Mapuche children who attended day care centers. Practice or Policy: We were able to confirm that type of care was not differentially associated with quality of the home environment. 相似文献
