Most Effective Lab Exercises

Readers are invited to share laboratory assignments for supervised laboratories, in accord with recommendations of the Task Force on the Core of Computer Science. An example of such a lab, focusing on program timing, is given in this section of the Computer Science Education journal.     

Most Effective Lab Exercises

A lab exercise in generating permutations can be very effective in two different computer science courses. In a first‐year computer science course, it is a good exercise in recursion, since it would be very difficult to do the problem without recursion. Second, in a Computer Organization or Assembly Language course, it reinforces very well the concepts of recursion and the use of a stack in implementing recursion, and drives home the idea that advanced data structures can be used in assembly language. Further concepts illustrated are the importance of analysing whether parameters should be var or value parameters, and the potential uses for a hardware stack.     

Most Effective Lab Exercises

A data base program that includes some inquiry capabilities can be effective in illustrating Prolog concepts. Having students do essentially the same task in Pascal first reinforces the concepts of relationships in a data base, and provides a firm foundation of understanding of the mechanisms used in a Prolog program.     

PCK--使教学最有效的知识

PCK是学科教学知识(Pedagogical Content Knowledge)的简称,是教师知识范畴中使教学最有效的知识。本文介绍了国外开展PCK研究的背景,PCK的内涵,PCK中整合的各种成分以及它的结构模型和检测的方法等,指出我国教师教育者应该重视PCK。     

练习量·有效练习·重复度

练习是学生掌握知识、形成技能、培养能力的一种必要的教学方法。练习的质量与学生的学习质量和学业负担有着密切的关系。教学实践证明：练习的质量与学习质量成正比，与学业负担成反比，即练习质量越高，学生的学习质量就越高，学业负担就越轻。在大力推进素质教育、向课堂要质量的情况下，对做为教学一个重要方面的练习，应当加以重视和研究。本文探讨与练习质量有关的 3个问题：练习量、有效练习、重复度。 一练习量 　　 　　练习量与练习质量的关系包含以下几层意思： 1提高练习质量，应确定科学的练习量 　　练习质量与练习量不一定…

Experiment to Determine the Most Effective Method of Teaching Current History

Two experiments were conducted to determine if expectancy to teach serves to increase learning beyond that produced by expectancy to be objectively tested. In the first experiment, Ss (N = 54) listened to a tape recorded lesson, with one-half the Ss expecting a following test and the other half expecting both to teach the same lesson to two other Ss and to be tested. Test results for both incentive conditions were nearly identical. In the second experiment, Ss (N = 54) read the lesson with half expecting to have their own lecture performances taped for playing before large audiences. Once, again, expectancy to teach did not affect learning. It was suggested that expectancy to teach may enhance learning only where students are motivated to increase amount of study activity, and have the opportunity to do so.

Handwriting: Copying Versus Tracing as the Most Effective Type of Practice

Abstract

Kindergarten and second grades Ss were given either copying or tracing practice exercises in teaching them to reproduce ten shorthand forms from memory. At the end of the five-week treatment period, the copying treatment group in both grades achieved significantly higher post test scores. No significant interaction between treatment condition and grade was found. Results corroborate the findings of an earlier study by Hirsch and Niedermeyer in which a different tracing strategy was employed.
