The coefficient alpha procedure has been used frequently to assess the reliability of student ratings of academic advising, despite the fact that in many cases, coefficient alpha is not an appropriate procedure for providing reliability information on this type of measurement data. Data were collected from 15 postsec ondary institutions' use of the Survey of Academic Advising, and a more advanced framework, that is, the generalizability theory, was used to analyze the reliability of the data. The results of the study demonstrate that the reliability of student ratings of advising can be estimated more appropriately and accurately by using the proce dures of generalizability theory. Advantages and disadvantages of the generalizabil ity theory approach in assessing the reliability of student ratings of advising are dis cussed in comparison with those of the coefficient alpha procedure. USING STUDENT RATINGS as an outcome assessment to evaluate the qual ity of advising programs is a common practice in many postsecondary educa tional institutions. The results of such assessment often play a critical role in decisions about the future of the individual advisor?decisions about promotions and tenure and about the advising program, such as whether or not to continue a specific program or service (Severy, Lee, Carodine, Powers, & Mason, 1994). To justify the credibility of a decision, the decisionmaker needs some assurance from the data that the same or similar results could be obtained if the same advi sors and advising programs were rated again under similar circumstances. In measurement theory terms, these ratings should have a desirable level of relia bility.
尽管在许多情况下,alpha系数并不是提供这类测量数据的可靠性信息的合适程序,但alpha系数程序已被频繁地用于评估学生对学术建议评分的可靠性。本研究收集了15所大专院校使用学术咨询调查的数据,并使用更高级的框架,即概括性理论,来分析数据的可靠性。研究结果表明,运用概括性理论可以更恰当、更准确地估计学生辅导评分的信度。通过与系数alpha法的比较,讨论了概化理论方法在评估学生建议评分可靠性方面的优缺点。在许多高等教育机构中,使用学生评分作为结果评估来评估咨询项目的质量是一种常见的做法。这种评估的结果通常在决定个别顾问的未来方面起着关键作用。关于晋升和任期的决定,以及关于咨询计划的决定,例如是否继续特定的计划或服务(Severy, Lee, Carodine, Powers, & Mason, 1994)。为了证明决策的可信度,决策者需要从数据中获得一定的保证,即如果在类似的情况下再次对相同的顾问和咨询项目进行评级,可以获得相同或类似的结果。在测量理论方面,这些评级应该有一个理想的可靠性水平。

How educational goals are conceptualized as a construct has implica tions for developing and evaluating educational programs and activities. The author used EQS 3.0 to test the factorial validity of 4 models of conceptualization of educa tional goals by conducting confirmatory factor analysis on empirical data collected from 1,134 education faculty members. The 4-factor model espoused by Goodlad fit the data best, and the participants wanted academic, vocational, personal, and social goals to be in relative harmony. Implications for educational theory, practice, and research are discussed. IN EDUCATIONAL THEORY AND PRACTICE, educational goals have been conceptualized in various ways. Some educators conceptualize educational goals as an all-inclusive, undifferentiated entity; others tend to view educational goals as the personal versus the social, or the academic versus the vocational; still others hold that the concept of educational goals includes personal, social, aca demic, and vocational elements. My purpose in the present study was to test the factorial validity of different conceptions of educational goals. The concept of educational goals has evolved in the history of educational thought. According to Walker and Soltis (1986), in The Republic the Greek philosopher Plato distinguished between the academic and vocational dimen sions of educational goals. The ancient Greeks believed that human beings had bodies that were animated and driven by a three-part soul. Each soul had an appetitive part, which expressed desires and needs and sought their fulfillment; a spirited part, which put aside unnecessary needs in the interests of self-protection and survival; and a rational part, which rose above both appetite and physical action to provide good judgment through reason. Therefore, according to Plato, educational goals were to provide academic education to people whose souls were dominated by rationality and to offer vocational education to those whose
如何将教育目标概念化为一个结构,对发展和评估教育计划和活动具有隐含意义。作者采用EQS 3.0对1134名教育教师的实证数据进行验证性因子分析,对4种教育目标概念化模型的因子效度进行检验。Goodlad支持的四因素模型最符合数据,参与者希望学术、职业、个人和社会目标相对和谐。讨论了对教育理论、实践和研究的启示。在教育理论与实践中,教育目标的概念是多种多样的。一些教育工作者将教育目标定义为一个包罗万象的、无差别的实体;其他人则倾向于将教育目标视为个人目标与社会目标,或学术目标与职业目标;还有一些人认为教育目标的概念包括个人的、社会的、学术的和职业的因素。在本研究中,我的目的是检验不同教育目标概念的析因效度。教育目标的概念是在教育思想史上发展起来的。根据Walker和Soltis(1986)的观点,希腊哲学家柏拉图在《理想国》中区分了教育目标的学术维度和职业维度。古希腊人相信人类的身体是由三部分的灵魂驱动的。每个灵魂都有一个欲望部分,表达欲望和需要,并寻求它们的满足;一个有精神的部分,为了自我保护和生存而把不必要的需要放在一边;还有一个理性的部分,它超越了欲望和身体行为,通过理性提供良好的判断。因此,柏拉图认为,教育的目标是为灵魂被理性支配的人提供学术教育,为灵魂被理性支配的人提供职业教育

Abstract A Monte Carlo evaluation of 4 test statistics for comparing dependent zero-order correlations was conducted. In particular, the power and Type I error rates of Hotelling's t; Williams' t; Olkin's z; and Meng, Rosenthal, and Rubin's Z were evaluated for sample sizes of 20, 50, 100, and 300 under 3 different population distributions (normal, uniform, and exponential). For the power analyses, 3 different magnitudes of discrepancy or effect sizes between ρy, x1 , and ρy, x2 were examined (values of .1, .3, and .6). Likewise, for the Type I error rate analyses, 3 different magnitudes of the predictor-criterion correlations were evaluated (ρy, x1 = ρy, x2 = .1, .4, and .7). All of the analyses were conducted at 3 different levels of predictor intercorrelation (ρx1, x2 = .1, .3, and .6). The results indicated that the choice as to which test statistic is optimal, in terms of power and Type I error rate, depends not only on sample size and population distribution but also on (a) the predictor intercorrel...
摘要对4个检验统计量进行蒙特卡罗评价,以比较相关零阶相关性。特别是霍特林t的幂和I型错误率;威廉姆斯的t;Olkin z;在3种不同的总体分布(正态分布、均匀分布和指数分布)下,对样本量为20、50、100和300的孟、Rosenthal和Rubin’s Z进行了评估。对于功效分析,检验了ρy, x1和ρy, x2之间的3个不同的差异大小或效应大小(值为.1,.3和.6)。同样,对于I型错误率分析,评估了3种不同程度的预测-标准相关性(ρy, x1 = ρy, x2 = .1, .4和.7)。所有分析均在三个不同的预测因子相关水平(ρx1, x2 = .1, .3和.6)下进行。结果表明,选择哪个检验统计量是最优的,在功率和I型错误率方面,不仅取决于样本量和总体分布,而且取决于(a)预测因子的相互关系。

Abstract Hierarchical data analyses in different disciplines are reviewed to compare statistical applications of the Hierarchical Linear Model (HLM) software and the SAS MIXED procedure. Similar features of the 2 programs are illustrated through use of the SAS MIXED procedure to confirm an HLM example. The SAS is a standard statistical package with a large group of users; discussions of the shared features in statistical computing may identify options to demystify existing methods for analyzing hierarchical data.

Abstract Three classes of middle-school students who received 1 year of problem-solving instruction were compared with 3 classes of students who were taught mathematics in a more traditional manner. At the end of the school year, all the students completed a questionnaire that explored their mathematical beliefs. In addition, 3 students of varying ability levels per class were interviewed and asked to solve 4 nonroutine problems. Compared with the students who had received traditional mathematics instruction, the students who had received problem-solving instruction displayed greater perseverance in solving problems, more positive attitudes about the usefulness of mathematics, and more sophisticated definitions of mathematical understanding. A limitation of the problem-solving instruction is that the students tended to equate problem solving with the problem-solving skills they had learned, seeing them as “rules” to solve all problems.

摘要:本文对3个接受1年解题教学的初中生与3个接受传统数学教学的初中生进行了比较。在学年结束时,所有学生都完成了一份调查他们数学信念的问卷。此外,每班还采访了3名不同能力水平的学生,并要求他们解决4个非常规问题。与接受传统数学教学的学生相比,接受问题解决教学的学生在解决问题方面表现出更大的毅力,对数学有用性的态度更积极,对数学理解的定义更复杂。问题解决教学的一个局限性是,学生倾向于把解决问题等同于他们所学到的解决问题的技能,把它们视为解决所有问题的“规则”。这些发现对数学教学改革的启示…

Family involvement with middle-grades homework: Effects of differential prompting 家庭参与对中年级家庭作业的影响:差异提示的影响

S. Balli, Jonathan Wedman, David H. Demo
A middle-grades homework intervention was investigated to determine if variations in prompting families to be involved with mathematics homework would influence their level of involvement. The extent to which family involvement was a predictor of student achievement in mathematics was also examined, as were the relationships among family involvement, student achievement, and parent education level. Families in the 2 prompted groups were significantly more involved with mathematics homework than were families in the no-prompt group. Level of family involvement was not significantly related to student achievement on the post-test. However, students across the 3 groups whose parent(s) held a 4-year college degree scored significantly higher on the post-test than did students neither of whose parents held a college degree, even though reported levels of family involvement were nearly identical across parent education levels. Qualitative data elicited in follow-up interviews with family members indicated that "quality of involvement" with homework merits examination in future research.
对中等年级家庭作业干预进行了调查,以确定促使家庭参与数学作业的变化是否会影响他们的参与程度。家庭参与对学生数学成绩的预测程度,以及家庭参与、学生成绩和父母教育水平之间的关系也进行了研究。两个提示组的家庭比没有提示组的家庭更积极地参与数学作业。家庭参与水平与学生后测成绩无显著相关。然而,父母拥有四年制大学学位的三组学生在事后测试中的得分明显高于父母都没有大学学位的学生,尽管报告的家庭参与水平在父母的教育水平上几乎相同。通过对家庭成员的随访访谈得出的定性数据表明,家庭作业的“投入质量”值得在未来的研究中进行考察。

Abstract Two experiments were conducted to determine the effects of reciprocal peer tutoring (RPT) on graduate students' academic achievement, test anxiety, and academic self-efficacy. In Experiment 1, students were assigned to one of two conditions—RPT or non-RPT. RPT students developed questions on specific course topics; they then used these questions to quiz other students before taking midterm and final course examinations. Contrary to previous research findings, the RPT and control groups did not differ significantly on lower cognitive or higher cognitive achievement measures. Students who used RPT generally reported that RPT improved their understanding of course content In Experiment 2, the RPT procedures were modifled to better match the procedures used in earlier studies whose authors had found RPT to be superior to non-RPT conditions. Also, the instruments were expanded to include course-relevant outcome measures of student academic self-efficacy and test anxiety. As in Experiment 1, the RPT an...
摘要本研究旨在探讨对等同伴辅导(RPT)对研究生学业成绩、考试焦虑和学业自我效能的影响。在实验1中,学生被分配到两个条件中的一个——rpt或非rpt。RPT学生针对特定的课程主题提出问题;然后,在参加期中和期末考试之前,他们用这些问题来测试其他学生。与之前的研究结果相反,RPT组和对照组在低认知成就和高认知成就方面没有显著差异。使用RPT的学生普遍报告说,RPT提高了他们对课程内容的理解。在实验2中,RPT程序被修改,以更好地匹配早期研究中使用的程序,这些研究的作者发现RPT优于非RPT条件。此外,这些工具被扩展到包括与课程相关的学生学业自我效能和考试焦虑的结果测量。在实验1中,RPT和…

Alexander and Govern's approximation : Providing an alternative to ANOVA under variance heterogeneity 亚历山大和戈文的近似:提供方差异质性下方差分析的替代方法
IF 2.2 4区 教育学 Q1 Social Sciences Pub Date : 1997-01-01 DOI: 10.1080/00220973.1997.9943459
P. Schneider, D. A. Penfield
A Monte Carlo simulation was conducted to compare the Type I error rate and power of the 1994 approximation developed by Alexander and Govern as an alternative to the ANOVA F test. It was compared with the ANOVA F, Kruskal-Wallis, Welch, Brown-Forsythe, and James second-order tests. The authors concentrated on the impact of various factors on Type I error rate and power. The factors included variance inequality, sample-size pairings with group variances, degree of skewness/kurtosis, and number of treatment groups. Under variance heterogeneity, Alexander-Govern's test was not only comparable to the performance of the Welch test and the James second-order test but was superior in certain instances.
进行了蒙特卡罗模拟,以比较Alexander和Govern开发的1994年近似的I型错误率和功率,作为ANOVA F检验的替代方法。比较方差分析F、Kruskal-Wallis、Welch、Brown-Forsythe和James二阶检验。作者着重研究了各种因素对I型错误率和功率的影响。这些因素包括方差不平等、与组方差的样本量配对、偏度/峰度和处理组的数量。在方差异质性下,Alexander-Govern检验不仅与Welch检验和James二阶检验具有可比性,而且在某些情况下优于Welch检验。

Abstract This longitudinal study was designed to compare the academic and personal characteristics of teacher candidates who persist and do not persist through teacher preparation and the early years of teaching. The candidates' (N = 551) characteristics were collected upon commencement of teacher preparation; 7 years later the candidates were classified by degree of persistence as follows: (a) not certified as teachers, (b) certified but not teaching, (c) part-time teachers, and (d) full-time teachers. The candidates' gender, major, initial assurance about teaching, and time at which they decided to become teachers were found to be associated with their degree of persistence; their level of academic aptitude, basic academic skills, and expected effectiveness as future teachers were found not to be associated with their degree of persistence. Relationships between these findings and findings from the National Longitudinal Survey of teacher attrition are discussed, and implications for effective teacher re...
摘要本纵向研究旨在比较在教师准备和早期教学中坚持和不坚持的教师候选人的学术和个人特征。在教师准备开始时收集候选人(N = 551)的特征;7年后,候选人按坚持程度分类如下:(a)未获得教师资格,(b)获得教师资格但不教书,(c)兼职教师,(d)全职教师。候选人的性别、专业、最初对教学的信心以及决定成为教师的时间与他们的坚持程度有关;研究发现,他们的学术能力水平、基本学术技能水平和未来教师的预期效果与他们的坚持程度无关。本文讨论了这些研究结果与全国教师流失纵向调查结果之间的关系,以及对有效教师培训的启示。

Abstract The mathematics self-efficacy and problem-solving performance of 327 middle-school students were assessed using two forms of assessment (traditional multiple-choice vs. open-ended fill-in-the-blank). The purpose was to determine whether varying the assessment format would influence students' self-efficacy judgments or alter the relationship between self-efficacy and performance. No differences in self-efficacy resulted from the different forms of assessment Students who took the multiple-choice performance test obtained higher scores than did students who took the open-ended test The latter group had poorer calibration, that is, the degree to which students' judgments of their capability reflect their actual competence. This finding suggests that students' self-perceptions of their mathematics capability may be less accurate than has previously been reported or that students' familiarity with traditional assessment formats creates an expectancy of a performance task that is multiple choice in nat...
摘要采用传统选择题和开放式填空两种形式对327名中学生的数学自我效能感和问题解决能力进行了测评。目的是确定不同的评估格式是否会影响学生的自我效能判断或改变自我效能与绩效之间的关系。自我效能感的差异不因评估形式的不同而产生。参加选择题表现测试的学生比参加开放式测试的学生得分更高,后者的校准较差,即学生对自己能力的判断反映实际能力的程度。这一发现表明,学生对自己数学能力的自我认知可能不如之前报道的那么准确,或者学生对传统评估形式的熟悉产生了对多项选择题的期望。
