Supplemental Instruction (SI) can be an efficient way of improving student success in difficult courses. Here, a study is made on SI attached to difficult first-year engineering courses. The results show that both the percentage of students passing a difficult first-year engineering course, and scores on the course exams are considerably higher for students attending SI, compared to students not attending. The study also shows that a higher percentage of female students attend SI, compared to male students. However, both genders seem to benefit to the same degree as a result of attending SI meetings. Also all students, independent of prior academic ability, benefit from attending SI. A qualitative study suggests that SI meetings provide elements important for understanding course material, which are missing from other scheduled learning opportunities in the courses. 相似文献

良好的学习方法,不论是内在的或外在的认知过程,只要能够促进知识概念的学习、能达到长久的记忆和灵活的运用都可称之为学习策略。文献上认为图解法能帮助学生彻底了解基本概念、分析及解题能力,图像表征不只让同学印象很深刻,更能提升同学的逻辑思考能力。研究以侨光科技大学的会计信息系的学生为实验对象,以成本会计科目作为实验教材,研究发现融入图解法教学的实验组学生,无论在后测成绩、进步幅度等整体成效均优于控制组,显示融入图解法教学之解题策略有助于提高解题之成效。研究显示,学习能力对成本会计题的学习成效有两个影响：第一,在整体解题成效分析中显示,高学习能力组学生的进步幅度较小,而对低学习能力组学生的效益较大;其次,在三大类型题个别成效分析中显示,在简单基本题及中等困难题高学习能力组的后测成绩虽较高,但进步幅度较小,而在复杂计算题显示高能力组学生在本题的解题表现略优于低能力组学生。 相似文献

Summary and Conclusion The basic questions involved in this investigation were the effect of initial standing and item difficulty on the gain established
on final over initial measures in achievement testing. The hypotheses were advanced that the use of gain discriminated against
bright students on two counts; first, by limiting possibility for gain and second, that equal gains might really represent
different levels of performance. It has been shown that the use of a measure of achievement, the effectiveness index, which
is independent of initial standing, shows a higher positive correlation with intelligence than the correlation obtained between
gain and intelligence. The use of partial correlation to hold the factor of initial standing constant raised the relation
found between gain and intelligence in 11 out of 12 cases, indicating that the higher initial standing of brighter students
tended to limit their performance. Further, it has been shown that the gain of bright students tends to be established on
more difficult items. In addition, the film apparently facilitated the success of students with above average intelligence
on difficult items since the relationship found between intelligence and gain or nongain on test items was markedly higher
in experimental than in control sections.
To the extent that the gains made on the tests employed in this investigation are representative of gains made on achievement
tests in general, in pretest and posttest situations, it may be concluded that bright students are discriminated against when
gain is the measure of performance. The bright students must overcome the twin difficulties of establishing their gain on
more difficult items in competition with students who havemore items on which improvement, i.e., gain, may be established. It is obvious that groups and individuals differing widely in
their initial performance on tests should not be compared using gain as a criterion unless there is some compensation for
these factors.
This paper funishes additional evidence relative to a statistical procedure—the “Effectiveness Index”—discussed by Hovland,
Lumsdaine, and Sheffield inExperiments on Mass Communication. It was originally presented to Section Q of the American Association for the Advancement of Science at the St. Louis Meeting,
December 1952. The Study was made possible by a grant from the University of Nebraska Research Council. Dr. Herbert A. Smith
is Associate Professor of Secondary Education and Supervisor of Science, the University of Nebraska. 相似文献

This paper assesses the contribution made by mature part-time students to the statistics on higher education. It shows that part-time numbers currently account for approximately 40% of total student numbers in the UK, 33% of university students, (mostly in the Open University) and 43% of the total in polytechnics and colleges, (1989–90 figures). The majority are mature people, over 25 years of age, who combine both education and employment. The principal change over the past ten years has been the increasing proportion of women, who now form more than 44% of the total number of students and 42% of the part-time total. A theoretical analysis is carried out, using the Human Capital model, which shows that part-time higher education might produce significant rates of return, both to the individual and society. It is noted that most of the research efforts in the UK, into the benefits of higher education, have concentrated on young, 18–21 year olds, who study full-time, and that current government policy is primarily concerned with improving the participation rate of this age group. This paper concludes that there is sufficient evidence to warrant a more thorough investigation of the costs and benefits of part-time study and suggests that there is considerable potential for expansion in this area. 相似文献

Revision is recognised as a key and complex element of the writing process. Despite this, research shows that students find it difficult effectively to revise their own writing due to a lack of metacognitive awareness and understanding of the processes they undertake when writing. The first part of this inquiry studies nine students’ understanding of the writing process and the revision strategies they employ using think‐aloud protocols and follow‐up interviews. Although the students all agreed that revision was an important part of improving their writing, they could not, or found it difficult to, articulate reasons for the changes they made to their writing. Therefore, the second part of the study explores the potential of collaborative writing to encourage and facilitate metacognitive talk through the implementation of a strategy where students are paired with a ‘writing buddy’. Observations of classroom work and interview responses of students showed that the scheme was successful in providing students with an experience of writing which was social, flexible and holistic, where talk is used to externalise thinking in order to develop a metacognitive understanding of the writing process. 相似文献

近年来,我国的高等教育取得了长足的发展,无论从各种层次的学校数量、在校生规模,还是教学质量都取得了令人可喜的成绩。但是,大量高校毕业生特别是营销管理类学生难以找到合适的就业岗位,究其原因主要是毕业生的规格和质量不能满足企业生产经营的需要。文章分析了当前市场营销专业在实践能力培养方面的误区,并提出了具体的培养途径。 相似文献
