Abstract. A multiple baseline design was employed to test the effect of manipulative instruction on the perimeter and area problem‐solving performance of middle and high school students who had been diagnosed with LD in the area of mathematics. Modeling, prompting/guided practice, and independent practice in conjunction with manipulative training were employed to teach both perimeter and area problem‐solving skills. Analysis of data revealed that the students rapidly acquired the problem‐solving‐skills, maintained these skills over a two‐month period, and transferred these skills to a paper and pencil problem‐solving format. This research extends previous findings by revealing that use of concrete manipulatives promotes the long‐term maintenance of skills. 相似文献

在秘鲁安第斯山脉的崇山峻岭中有一座神秘的古城。西班牙人在长达300年的殖民统治期间对它一无所知,秘鲁独立后的100年间也无人涉足。400多年的时光,只有翱翔的山鹰得以一睹古城的雄姿,它就是马丘比丘印加遗址。作为马丘比丘的"姐妹城",肖克奎拉奥可谓是寂寂无名,但却有着马丘比丘无可比拟的孤独与安静。本文作者向我们介绍了在肖克奎拉奥的徒步探险经历,巨石垒筑的残垣断壁正向我们讲述着当年的故事.我们还会感受到怀古的幽思、逝去的光华,以及领略这座古城记载着的印加人无与伦比的智慧。 相似文献

Instructional theory is intended to guide instructional designers in selecting the best instructional methods for a given situation. There have been numerous qualitative investigations into how instructional designers make decisions and the alignment of those decisions with theoretical influences. The purpose of this research is to more quantitatively explore the question of how instructional designers actually use instructional planning theory to judge the usefulness of instructional methods. We asked 56 instructional designers to rate the usefulness of 31 instructional methods for six different cognitive domain content level conditions. The results show that content level has a statistically-significant influence on a designer’s judgments regarding the usefulness of an instructional method. A designer’s gender also has a statistically-significant influence on a designer’s judgments regarding methods, but a weak effect size limits this result. Overall, the results provide evidence that supports the core principles of instructional planning theory, specifically method generality. The results also provide instructional designers further guidance in selecting the most useful instructional methods for cognitive domain content levels. 相似文献

那天是1997年3月13日。我当时把车停进车库,然后走进厨房。那一刻,我震惊得完全哑口无言。窝在桌子上一个小花篮里的是一只可爱的杏色小贵宾犬,它直愣愣地盯着我看。毫无疑问,我对它一见钟情,而这种爱意一直延续,直至瞑目,直至永远。布鲁娜从那天起就进入了我的生活。那时候, 相似文献

在北京住上一段时间后,你就会对空气有更细致的感受。在北京住了七年后,我感觉自己有点像那些坊间杜撰的爱斯基摩人,传说能用30个词精准地描述不同的雪。在北京,我们谈论空气净化器,其方式就像青年男孩子们经常谈论汽车一样。我曾不止一次去一位朋友家里,无 相似文献

Project Ga‐GEMS (Georgia's Project for Gifted Education in Math and Science) viewed the effect that placement in an integrated, hands‐on mathematics and science curriculum had on the achievement of academically talented high school students. For a two‐year period of time, students gifted in the areas of mathematics and science participated in a curriculum which incorporated higher‐level thinking skills and more real life laboratory experiences into mutually reinforcing mathematics and science lessons. After the conclusion of the two‐year program, Ga‐GEMS participants and a control group were given the mathematics and science sections of the ACT as they exited the tenth grade. The Ga‐GEMS students scored significantly higher on the Science Math Total, Pre‐Algebra/Elementary Algebra, Intermediate Algebra/Coordinate Geometry and Plane Geometry/Trigonometry sections of the ACT. To determine if the Ga‐GEMS students retained their higher scores throughout high school the SAT scores of both groups were compared as the students exited high school. Significant differences in the areas of total score and mathematics were noted. This study lends support for the use of a differentiated curriculum for educating gifted students in science and mathematics. 相似文献
