Stimulating Prewriting Skills with the Help of Pictorial Images     

Uršula Podobnik 《Teaching Artist Journal》2017,15(2):51-63

Increasingly, children who start school have already acquired basic reading and writing skills provided by their parents or preschool teachers. However, even if we choose to accept the fact that by teaching preschool children how to read and write parents wish to help them integrate successfully into the school environment and methods of work, we still need to emphasize that certain activities are not in balance with the needs, abilities, and potentials of a preschool child. At the same time some other possibilities are not being used enough (e.g., visual art). The present research introduces this aspect and presents training prewriting skills based on visual art activities given that visual art represents one of the primary media that every child spontaneously uses in his or her preschool years.  相似文献

蒲慕明:做一个有品德的科学家          下载免费PDF全文

蒲慕明 《中国科学院院刊》2006,21(1):2-3

科学家不是生存在真空中,而是生活在一个社会里。一个有品德的科学家才能受学术界和社会的尊重,他的工作才使人信服。有品德的科学家是严谨的、讲公德的、有诚信的、尊重事实并捍卫真理的。不要有了结果,即使数据靠不住,自己都不能信服的东西,也要出文章。今年这文章出了,下面做不下去了,别人不能重复,那你的名声就毁了。不要因为眼前要出一篇文章,将来后患无穷。严谨态度要从小事做起,你到公用实验室使用仪器,该签名时就签,应该怎样操作就怎样操作,要守规矩。图省事、走“捷径”和占小便宜,成了习惯,最后就会犯大错。我们在学习阶段,就要培…  相似文献

Personality traits as a predictor of academic achievement in adolescents     

Helena Smrtnik‐Vitulić  Maja Zupančič 《Educational studies》2011,37(2):127-140

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   

Negative school factors and their influence on math and science achievement in TIMSS 2003     

Tina Vršnik Perše  Ana Kozina  Tina Rutar Leban 《Educational studies》2011,37(3):265-276

The aim of the present study was to conduct an analysis of TIMSS (Trends in International Mathematics and Science Study) 2003 database and to determine how negative school factors, such as aggression, are associated to the mathematical and science achievement of students. The analyses were conducted separately for national and international data. National analyses for Slovenia show significant associations between math and science achievement and the experience of aggressive behaviour. Students who experienced aggressive behaviour scored lower in math and science, both in the fourth and in the eighth grade. The results of the regression analysis show that negative factors, such as aggressive behaviour, are good predictors of educational achievement in Slovenia. International analyses for the selected countries (high‐ and low‐achieving countries from the whole TIMSS population) confirm that this type of finding is culturally impartial as well as valid for the level of achievement both in math and in science.  相似文献
