The study examined the predictive value of adolescents’ personality trait ratings by different groups of informants in explaining academic achievement [grade point average (GPA)] while controlling for students’ sex and their mothers’ education. The Inventory of Child/Adolescent Individual Differences was employed as a measure of students’ personality traits at the end of elementary schooling (mean age = 14.7 years) and two years later when the participants attended secondary schools. The trait ratings were obtained through self‐, maternal and peer reports at both measurement occasions. They explained substantial portions of unique variance in the students’ GPA concurrently, and over time. Ratings by each of the three groups of informants had an incremental validity over one another in predicting school grades. Among personality variables, conscientiousness and low extraversion were consistently predictive of GPA. 相似文献

Based on findings from a semester-long study, this article examines the development of Samoan prospective teachers’ mathematical understandings and mathematics attitudes when investigating authentic contexts and applying working mathematically processes, mental computations and problem-solving strategies to find solutions of problems. The prospective teachers had enrolled for the second time (having failed their first attempt), in the first-year mathematics methods course of a 2-year Diploma of Education (Primary) programme. The group also included those enrolled in the Diploma of Education (Early Childhood and Special Needs) programmes, who recognizing their own limited understanding of mathematics would ordinarily shy away from opportunities for improvement. Given the negative mathematical and learning experiences, this group was ideal to engage in innovative and creative approaches that would make mathematics learning more meaningful and contextual in a Samoan environment. Only data from the attitudinal questionnaires and interviews are presented in this article. Main findings have implications for teaching and learning mathematics. 相似文献

The Federal Assembly of the Czechoslovak Socialist Republic approved, on 10 April 1980, the new law (Nr.39/80) on higher education. This law was under preparation nearly three years by the Czech and Slovak ministries of education and representatives of universities and other institutes of higher education as we'll as experts in charge of economic and social development. Starting from 1 September 1980 it will replace the previous law on higher education (Nr. 19/66) that has been in effect since 1966.
The following article, written for “Higher Education in Europe” by Professor Jiri M#akeri?ka, Director of the Research Institute on Engineering Studies in Prague, presents the main elements of this new law. 相似文献

All live systems acquire and use knowledge to ensure appropriate efficiency in the mutual intercourse with the surrounding environment. Knowledge can be communicated only when the subject's internal model of the object of reality is objectified by means of a certain set of physical signs. Such an externalized model, a communicate, is to be accepted, adequately understood and evaluated by other relevant live systems. The information value of a communicate is therefore a function not only of the communicate itself but of the needs, aims, expectations and possibilities of relevant live systems as well. The information value of the same communicate can vary within a set of those systems. The determination of regularities in the relations between the information value of communicates, their content similarity and distinctive features of live systems producing and using them is a problem for experimental and empirical studies. 相似文献
