Skinner (1958) expressed the need for an increase in the effectiveness and efficiency of education. In particular, he suggested that programmed instruction could provide such efficiency. The present study used a within-subject design to compare the effects of four types of instructional materials; those requiring overt construction responses, overt discrimination responses, covert reading of text with highlighted key words, and covert reading of standard text. The materials requiring overt responding produced greater learning than did the covert reading materials, with or without highlighting. There was no difference found between the two types of overt responding; nor were there differences between the two types of covert reading materials. Thus, this study supports the assumption that overt responding is more effective. However, the overt response materials also required proportionately more time. Therefore, this showed no benefit of overt responding in terms of efficiency.  相似文献

Students (N=153) in three equivalent sections of an undergraduate human development course compared pairs of related concepts via either written or oral discussion at the beginning of most class sessions. A writing-for-random-credit section achieved significantly higher ratings on the writing activities than did a writing-for-no-credit section. The writing-for-random-credit section also obtained significantly higher correlations between the writing ratings and scores on multiple-choice exam items related to the conceptual pairs (r=.74) and on total exam scores (r=.78) than did the writing-for-no-credit section (rs=.45 and .43, respectively). Finally, the writing-for-random-credit condition produced significantly higher scores on exam items related to the conceptual pairs than did the oral-discussion-only condition. Plus, effect-size comparisons showed weak to medium differences between exam scores under the writing-for-random-credit and the writing-for-no-credit condition.  相似文献

Short-term memory (STM) models distinguish between item and order memorization. The present study aims to explore how item and order STM are affected by the nature of the stimuli, the sequential versus simultaneous mode of presentation, the visual versus auditory presentation modality, the possibility of verbal recoding. A total of 20 children with dyslexia were matched one-by-one with 20 typically reading children on sex, age (8–14 years), and grade. Computerized STM tasks were administered while manipulating type (item vs. order), stimuli (letters vs. colors), sequentiality, input and output modality, as well as the presence/absence of articulatory suppression and distractors. General Linear Model analyses were conducted on accuracy scores for item and order STM. Both item and order recall scores were lower for children with dyslexia. Although order STM in the visual input condition turned out to be more impaired than item STM in the dyslexic group, both item and order memory impairments become evident when verbal recoding is prevented through articulatory suppression. Moreover, dyslexic children, unlike typical readers, were not facilitated by the linguistic nature of the stimuli to be remembered. The present findings suggest that the often-reported selective impairment of serial memory in dyslexia is restricted to stimuli that are verbal in nature or can be verbally recoded, whereas both item and order memory impairments become evident when verbal recoding is prevented through articulatory suppression. The presence of distractors is particularly detrimental to STM in the dyslexic group. The sensitivity to distractors, suppression, and stimuli in STM is predictive of reading performance.  相似文献

In many low‐ and middle‐income countries, young children learn a mother tongue or indigenous language at home before entering the formal education system where they will need to understand and speak a country's official language(s). Thus, assessments of children before school age, conducted in a nation's official language, may not fully reflect a child's development, underscoring the importance of test translation and adaptation. To examine differences in vocabulary development by language of assessment, we adapted and validated instruments to measure developmental outcomes, including expressive and receptive vocabulary. We assessed 505 2‐to‐6‐year‐old children in rural communities in Western Kenya with comparable vocabulary tests in three languages: Luo (the local language or mother tongue), Swahili, and English (official languages) at two time points, 5–6 weeks apart, between September 2015 and October 2016. Younger children responded to the expressive vocabulary measure exclusively in Luo (44%–59% of 2‐to‐4‐year‐olds) much more frequently than did older children (20%–21% of 5‐to‐6‐year‐olds). Baseline receptive vocabulary scores in Luo (β = 0.26, SE = 0.05, p < 0.001) and Swahili (β = 0.10, SE = 0.05, p = 0.032) were strongly associated with receptive vocabulary in English at follow‐up, even after controlling for English vocabulary at baseline. Parental Luo literacy at baseline (β = 0.11, SE = 0.05, p = 0.045) was associated with child English vocabulary at follow‐up, while parental English literacy at baseline was not. Our findings suggest that multilingual testing is essential to understanding the developmental environment and cognitive growth of multilingual children.  相似文献

双因子模型假设测验考察一个一般因子和多个组因子,符合很多教育和心理测验的因素结构。“维度缩减”方法将参数估计中多维积分计算化简为多个迭代二维积分,是双因子模型的重要特征。本文针对考察多级评分项目的计算机化自适应测验,首先推导双因子等级反应模型下Fisher信息量的计算,然后推导“维度缩减”方法在项目选择方法中的应用,最后在低、中、高双因子模式题库中比较D-优化方法、后验加权Fisher信息D优化方法(PDO)、后验加权Kullback-Leibler方法(PKL)、连续熵(CEM)和互信息(MI)方法在能力估计的相关、均方根误差、绝对值偏差和欧氏距离的表现。模拟研究表明:(1)双因子模式越强,即一般因子和组因子在项目上的区分度的差异越小,一般因子估计精度降低,组因子估计精度增加,整体能力的估计精度提高;(2)相同实验条件下,连续熵方法的测量精度最高,PKL方法的能力估计精度最低,其它方法的测量精度没有显著差异。  相似文献

Prior research has examined interventions to prevent prompt dependence from occurring during the training of novel skills. Nevertheless, the relative efficacy and efficiency of different intervention procedures may be idiosyncratic across learners, suggesting the potential benefit of an individualized assessment. The purpose of the current study was to extend the literature on prompt dependence by comparing interventions for 3 participants with developmental disabilities who consistently engaged in correct responses following prompts but did not perform tasks independently. We compared the efficacy and efficiency of 3 interventions including differential reinforcement, prompt fading, and extended response interval. Intervention results differed across participants, indicating that the most efficacious and efficient intervention for prompt dependence should be individualized via assessment.  相似文献

Four studies developed and validated two dictionaries to capture agentic and communal expressions in natural language. Their development followed the Linguistic Inquiry and Word Count (LIWC) approach (Study 1) and we tested their validity with frequency-based analyses and semantic similarity measures. The newly developed Agency and Communion dictionaries were aligned with LIWC categories related to agency and communion (Study 2), and corresponded with subjective ratings (Study 3), confirming their convergent validity. Very low or absent correspondence between proposed dictionaries and unrelated LIWC categories demonstrated their discriminant validity (Study 2). Finally, we applied both dictionaries to language used in advertisements. In correspondence to gender stereotypes, male-dominated jobs were advertised with more agentic than communal words, and female-dominated jobs with more communal than agentic words (Study 4). Both dictionaries represent reliable tools for quantifying agentic and communal content in natural language, and will improve and facilitate future research on agency and communion.  相似文献

We investigated whether seductive details (i.e., interesting but irrelevant adjuncts) are harmful to learning only when students (mistakenly) think that they are relevant. We therefore conducted a study in which participants (N = 86) learned either without seductive details (control condition) or with seductive details—in the latter case with or without being informed about the seductive details' irrelevance. In line with our hypotheses, only participants who were not informed about the irrelevance of seductive details revealed worse learning outcomes than those in the control condition, thereby revealing a seductive details effect. Extraneous cognitive load, but not perceived time pressure, mediated the negative effects of being uninformed about the irrelevance of seductive details on learning outcomes. Taken together, our results suggest that the perceived relevance of seductive details is a boundary condition of the seductive details effect.  相似文献
