The authors investigated 2 issues concerning the power of latent growth modeling (LGM) in detecting linear growth: the effect of the number of repeated measurements on LGM's power in detecting linear growth and the comparison between LGM and some other approaches in terms of power for detecting linear growth. A Monte Carlo simulation design was used, with 3 crossed factors (growth magnitude, number of repeated measurements, and sample size) and 1,000 replications within each cell condition. The major findings were as follows: For 3 repeated measurements, a substantial proportion of samples failed to converge in structural equation modeling; the number of repeated measurements did not show any effect on the statistical power of LGM in detecting linear growth; and the LGM approach outperformed both the dependent t test and repeated-measures analysis of variance (ANOVA) in terms of statistical power for detecting growth under the conditions of small growth magnitude and small to moderate sample size conditions. The multivariate repeated-measures ANOVA approach consistently underperformed the other tests.
作者研究了关于潜在生长模型(LGM)检测线性增长的能力的两个问题:重复测量次数对LGM检测线性增长能力的影响,以及LGM与其他一些方法在检测线性增长能力方面的比较。采用蒙特卡罗模拟设计,在每个细胞条件下有3个交叉因素(生长幅度、重复测量次数和样本量)和1000个重复。主要发现如下:对于3次重复测量,相当大比例的样本在结构方程建模中未能收敛;重复测量的次数对LGM检测线性生长的统计能力没有任何影响;在小增长幅度和小到中等样本量条件下,LGM方法在检测增长的统计能力方面优于依赖t检验和重复测量方差分析(ANOVA)。多变量重复测量方差分析方法的表现一直低于其他测试。

Abstract The author used confirmatory factor analysis (CFA) to model self-regulation subprocesses as latent concepts in an examination of the effectiveness of peer modeling for teaching self-regulation. The design was a nonequivalent pretestposttest control group design with 63 participants (52 women and 11 men). The experimental group received self-regulation training through a self-regulation videotape and a peer-advocated action plan. The control group received no training. Difference scores were calculated for both groups and analyzed with analysis of variance. The author used a 50-item Likert-type Self-Regulation Inventory (SRI) as a pretest and posttest to measure participants' self-regulatory attitudes and behaviors. The experimental group performed significantly better than the control group. The author used CFA to test the goodness of fit between a hypothesized model of self-regulation and the sample data. On the basis of a priori specification of the CFA model, the author predicted that response...
摘要本文采用验证性因子分析(CFA)对自我调节子过程作为潜在概念进行建模,以检验同伴建模对教学自我调节的有效性。设计为63名参与者(52名女性和11名男性)的非等效测试前和测试后对照组设计。实验组通过自我调节录像带和同伴倡导的行动计划接受自我调节训练。对照组不接受任何训练。计算两组的差异评分,并进行方差分析。采用李克特自我调节量表(Likert-type Self-Regulation Inventory, SRI)作为前测和后测,对被试的自我调节态度和行为进行测量。实验组的治疗效果明显优于对照组。作者使用CFA来检验自我调节假设模型与样本数据之间的拟合优度。在对CFA模型进行先验规范的基础上,作者预测:

Abstract Research situations occur in which data are obtained from a small group of rare experimental participants. An alternative strategy to comparing the experimental group with a control group of comparable sample size is to use a large control group for statistical comparison. That strategy increases the probability that the control group will provide an accurate benchmark for statistical comparison and is recommended as a method to increase statistical precision. However, traditional statistical procedures cannot ensure accurate error rates when data with highly unequal cell frequencies are being analyzed. The author presents an alternative statistical test (BOOTmed) for the 2-group situation when a small experimental group is compared with a large control group. BOOTmed is a between-groups median test derived via bootstrapping techniques. Empirical evaluation indicated that BOOTmed maintains relatively robust error rates during a variety of test conditions.
摘要研究情况发生在数据从少数实验参与者获得的情况下。将实验组与具有可比较样本量的对照组进行比较的另一种策略是使用较大的对照组进行统计比较。该策略增加了控制组为统计比较提供准确基准的可能性,并被推荐为提高统计精度的方法。然而,传统的统计方法在分析具有高度不均匀的小区频率的数据时,不能保证准确的错误率。当一个小的实验组与一个大的对照组进行比较时,作者提出了两组情况的另一种统计检验(BOOTmed)。BOOTmed是通过自举技术得出的组间中位数检验。经验评估表明,BOOTmed在各种测试条件下保持相对稳健的错误率。

Abstract The effects of postorganization activities on the acquisition of information presented in a knowledge-map format were assessed. In the 1st experiment, the students studied biology subject matter in a knowledge-map format for 30 min. During the next 15 min, half of the participants summarized the information using the structure of the map (without any text included) as an aid (structure group); the other half continued studying the map (control group). The structure group recalled significantly more information than the control group did; that effect was particularly pronounced with recall of superordinate propositions. In Experiment 2, the recall of the structure group, who studied in the same manner as in Experiment 1, was compared with that of the map group, who summarized using the knowledge map as an aid, and the no-cue group, who summarized without any type of aid. The map and structure groups recalled significantly more superordinate propositions than the no-cue group. The 3 groups did not ...
摘要:本文评估了组织后活动对知识地图格式信息获取的影响。在第一个实验中,学生以知识地图的形式学习生物主题30分钟。在接下来的15分钟中,一半的参与者使用地图的结构(不包含任何文本)作为辅助来总结信息(结构组);另一半继续研究地图(对照组)。结构组回忆的信息明显多于对照组;这种效果在回忆高级命题时尤为明显。在实验2中,采用与实验1相同的学习方式进行记忆的结构组与以知识地图作为辅助工具进行记忆总结的地图组和不使用任何辅助工具进行记忆总结的无线索组的回忆进行了比较。地图组和结构组比没有提示的组回忆起更多的高级命题。这3组没有…

Abstract In 3 experiments, the author examined the effects of cognitive load management by inserting vocabulary definitions into reading passages. In Experiment 1, for 5th-grade readers of English as a 2nd language (ESL), vocabulary definitions integrated within a passage (integrated format) improved comprehension (high-level processing), whereas a separate vocabulary list (separated format) improved vocabulary learning (low-level processing). In Experiment 2, for 8th-grade ESL learners, the separated format improved comprehension, whereas the integrated format improved vocabulary learning. In Experiment 3, with university students, there was a Format × Level interaction effect similar to that in Experiment 2. Efficiency of instruction depends partly on its ability to manage cognitive load. An identical presentation format may facilitate learning by reducing cognitive load but may interfere with learning through either split-attention or redundancy effects, depending on learner expertise.

摘要通过三个实验,作者考察了在阅读段落中插入词汇定义对认知负荷管理的影响。在实验1中,对于五年级英语作为第二语言(ESL)的读者来说,整合在一篇文章中的词汇定义(整合格式)促进了理解(高水平加工),而单独的词汇表(分离格式)促进了词汇学习(低水平加工)。在实验2中,对于八年级的ESL学习者来说,分离格式提高了理解能力,而整合格式提高了词汇学习能力。在以大学生为对象的实验3中,存在与实验2相似的Format × Level交互效应。教学的效率部分取决于其管理认知负荷的能力。相同的演示格式可以通过减少认知负荷来促进学习,但可能会通过注意力分散或冗余效应干扰学习,这取决于学习者的专业知识。对于经验较少的人来说……

Abstract Students solved mathematics problems from 4 assignment pairs. Each control assignment contained 18 target multiplication problems that were 4 × 1-digit (4 × 1), 4 × 2, 4 × 3, or 4 × 4. Each paired experimental assignment contained 18 similar problems plus 6 interspersed 1 × 1-digit problems. After computing problems from each pair of assignments, the students rated them and chose 1 for homework. Across all assignment pairs, problem completion rates were greater on the experimental assignments, and significantly more students chose a new experimental, rather than control, assignment for homework. Furthermore, as the discrepancy between problem completion rates increased across assignment pairs, the probability of students' choosing the experimental assignment for homework and rating the experimental assignment more favorably with respect to difficulty, effort, and time also increased. The relationship between student choice behaviors and relative problem completion rates has theoretical and applie...
学生从4对作业中解决数学问题。每个控制任务包含18个目标乘法问题,分别为4 × 1、4 × 2、4 × 3或4 × 4。每个配对的实验作业包含18个类似的问题加上6个分散的1 × 1位数问题。在计算出每对作业中的问题后,学生们对它们进行评分,并选择1作为家庭作业。在所有的作业对中,实验作业的问题完成率更高,更多的学生选择新的实验作业作为家庭作业,而不是对照作业。此外,随着作业对之间的问题完成率差异的增加,学生选择实验作业作为家庭作业并在难度、努力和时间方面对实验作业给予更有利评价的可能性也增加了。学生选择行为与相对问题完成率之间的关系具有理论和应用价值。

Abstract The standard nonparametric 1-sample runs test, which is based on the total number of runs, has recently been found to give anomalous results in the case of data consisting solely of runs of length 2. Furthermore, tests based on the total number of runs provide little information as to the length of the individual runs. An explanation for that anomaly is provided, and tests based on the length of runs are described. Such tests can be successfully applied to runs of length 2 but usually use asymptotic methods of assessing statistical significance. In addition, such tests generally impose arbitrary limits as to the maximum run length. A new procedure that allows the maximum run length to be empirically determined is described. In that procedure, one uses a Monte Carlo permutation test to ascertain statistical significance. The new Monte Carlo omnibus length-of-runs procedure is illustrated with examples from suicide research and from psycholinguistics.
基于总运行次数的标准非参数1样本运行测试最近被发现在数据仅由长度为2的运行组成的情况下给出异常结果。此外,基于总运行次数的测试几乎不能提供关于单个运行长度的信息。提供了对该异常的解释,并描述了基于运行长度的测试。这种检验可以成功地应用于长度为2的运行,但通常使用评估统计显著性的渐近方法。此外,这种测试通常对最大运行长度施加任意限制。描述了一种新的程序,允许最大行程长度的经验确定。在这个过程中,人们使用蒙特卡罗排列检验来确定统计显著性。新的蒙特卡罗综合长度运行程序说明了例子,从自杀研究和心理语言学。

Power to detect additive treatment effects with randomized block and analysis of covariance designs 用随机区组和协方差设计分析检测加性处理效果的能力

Abstract The power of analysis of covariance (ANCOVA) and 2 types of randomized block designs were compared as a function of the correlation between the concomitant variable and the outcome measure, the number of groups, the number of participants, and nominal power. ANCOVA had a small but consistent advantage over a randomized block design with 1 participant in each Block × Treatment combination (RB1). At correlations of .3 or greater, ANCOVA was superior to a randomized block design with n participants per Block × Treatment combination (RBn), with increasing differences as the correlation increased. RBn was superior to the other 2 designs only when the correlation was .2 or less. At those levels, however, the randomized group analysis of variance ignoring the concomitant variable was equally powerful. The findings held regardless of sample size, number of groups, or nominal power.
摘要比较两种随机区组设计的协方差分析(ANCOVA)能力与伴随变量与结果测量值、组数、参与者数和标称能力之间的相关性。与随机分组设计相比,ANCOVA具有较小但一致的优势,每个分组×治疗组合(RB1)有1名参与者。在相关性为0.3或更高时,ANCOVA优于随机分组设计,每个分组×治疗组合(RBn)有n名参与者,随着相关性的增加,差异也越来越大。RBn仅在相关系数小于等于0.2时优于其他2种设计。然而,在这些水平上,忽略伴随变量的随机分组方差分析同样有效。无论样本大小、组数或名义功率如何,研究结果都是成立的。

Abstract The influence of prewriting treatments on the quality of written discourse produced by 5th-grade students was the central focus of this research. Students received 1 of 4 prewriting treatments: reading paired with prewriting, prewriting-only, reading-only, or neither reading nor prewriting. Differences in the quality of the students' compositions were examined on the basis of scores obtained from a T-unit measure, a holistic rubric, and an analytic measure. The study included 5 classes of 5th-grade students randomly assigned to classes at the beginning of the school year. Four classes (n = 96) were randomly designated as treatment groups, and the 5th class (n = 24) served as a pilot group. A significant (p < .001) multivariate F-ratio indicated that type of prewriting treatment significantly affected scores on expository compositions. Reading paired with prewriting before composing was found to be the most effective prewriting instructional strategy.
摘要本研究主要探讨写作前处理对五年级学生书面语篇质量的影响。学生们接受了四种预写处理中的一种:阅读搭配预写、只预写、只阅读或既不阅读也不预写。学生作文质量的差异是根据从t单位测量、整体标题和分析测量中获得的分数来检查的。这项研究包括5个班的五年级学生,他们在学年开始时被随机分配到不同的班级。随机选取4个班(n = 96)作为治疗组,第5个班(n = 24)作为试验组。一个显著的(p < 0.001)多变量f比表明写作前治疗的类型显著影响说明文作文的得分。写作前阅读与写作前写作相结合是最有效的写作前教学策略。

Abstract Relations among achievement, self-concept, and motivation in mathematics and language arts were examined in a longitudinal 2-wave, 3-variable panel study. The participants were 3 cohorts of Norwegian elementary and middle school students (N = 1,005). The 1st data collection took place in October and November 1996, when the students in the 3 cohorts attended 3rd, 6th, and 8th grades. The 2nd data collection took place 1 academic year later. LISREL 8 was used in the separate analyses of mathematics and language arts data; the data were analyzed for each cohort by means of 6 path analyses for latent variables. In all cohorts, the results were consistent with a skill-development model of the achievement-self-concept relation, that is, the view that achievement affects subsequent self-concept. No evidence was found that self-concept affects subsequent achievement (self-enhancement model). Moreover, in the 2 oldest cohorts, motivation was affected by previous achievement. However, there was no evidence...
摘要采用纵向两波、三变量面板研究,对数学和语言艺术成绩、自我概念和动机之间的关系进行了研究。研究对象为3组挪威中小学生(N = 1,005)。第一次数据收集于1996年10月和11月进行,当时三个队列中的学生就读于三年级,六年级和八年级。第二次数据收集是在一个学年之后进行的。使用lisrel8对数学和语言艺术数据进行单独分析;对每个队列的数据进行6个潜在变量的通径分析。在所有队列中,结果都符合成就-自我概念关系的技能发展模型,即成就影响随后的自我概念的观点。没有证据表明自我概念影响随后的成就(自我增强模型)。此外,在年龄最大的两组中,动机受到先前成就的影响。然而,没有证据表明……
