初中教师教学有效性评价问卷的编制:以学生为评价主体的视角

在教学有效性的框架下,从学生评价的视角,编制了《初中生评价教师教学有效性问卷》。首先,在理论研究的基础上,通过项目的收集,结构化问卷调查,项目的重要性分析三个过程形成初测问卷。然后,进行初测问卷的施测,通过区分度分析和验证性因素分析删除项目,最终形成《初中生评价教师课堂教学效果问卷》的正式问卷。最后,对所编制的问卷的心理测量学指标进行了检验,结果表明该问卷具有良好的结构效度、交叉效度和较高的内部一致性信度。     

过分自信的进化模型

过分自信有狭义和广义之分, 狭义的过分自信是指人们对自身绝对水平的高估, 使得对自己的评价优于实际水平, 广义的过分自信是一种非理性的过于优化的估计, 还包括对自身相对水平的高估。基于进化心理学理论和生态理性假设提出的进化模型认为, 过分自信是一种快速启发式认知策略, 在适应和生存中具有优势, 是进化选择的结果。根据对个体知觉偏差的不同假设, 进化模型分为二项式模型和正态模型, 都得出了一致的研究结论。与过分自信的自我提升理论、权重差异理论和信息差异理论相比较, 进化模型具有许多优点, 但也存在一些不足, 需要进一步对其进行探讨和检验。     

基因-环境交互作用理论模型及其检验方法

素质?压力模型、不同易感性模型和优势敏感性模型是当前有关基因?环境交互作用的三种代表性理论模型。素质?压力模型认为“近墨者黑”或“出淤泥而不染”, 优势反应敏感性模型认为“近朱者赤”, 而不同易感性模型则兼收并蓄, 认为某些个体近墨则黑, 近朱则赤。检验上述模型的现实有效性是当前基因?环境交互作用研究领域的热点问题之一。概观而言, 分组回归和分层回归是常用的传统检验方法, 显著性区域分析法和新参数回归模型法则是新近兴起的。未来研究需要进一步探索三种模型的领域特殊性、种族差异等问题, 检验这些模型的方法也有待改善。     

A fast numerical algorithm for the estimation of diffusion model parameters

In this paper, we describe a new algorithmic approach for parameter estimation in Ratcliff's [(1978). A theory of memory retrieval. Psychological Review, 85 (2), 59-108] diffusion model. This problem, especially if inter-trial variabilities of parameters are included in the model, is computationally very expensive; the parameter estimation procedure often takes a long time even with today's high-speed computers. The algorithm described here makes the calculation of the cumulative distribution functions for predicted process durations computationally much less expensive. This improvement is achieved by solving the Kolmogorov backward equation numerically instead of employing the previously used closed form solution. Additionally, the algorithm can determine the optimum fit for one of the model parameters (the starting point z) directly, thereby reducing the dimension of the parameter search space by one. The resulting method is shown to be notably faster than the standard (closed-form solution) method for parameter estimation.     

The pedagogical imperative of values education

Recent research has exposed the potential of quality teaching to exercise a positive influence on student achievement. Extending beyond surface and factual learning, quality teaching has posited conceptions of ‘intellectual depth’, ‘communicative competence’ and ‘self‐reflection’ as being central to effective learning. Implicit in these conceptions are values dimensions reflected in notions of positive relationships, the centrality of student welfare, school coherence, ambience and organisation. The influences of these on student learning, welfare and progress have been observed across public, private and religious sectors, thus confirming earlier studies of similar phenomena in religious schools. Evidence from the Australian Government's Values Education Good Practice Schools Project indicates the benefit to all schools of reflecting on, re‐evaluating and rethinking the implications of values education for curricula, classroom management and school ethos in the interests of student wellbeing and progress. This indicates a pedagogical imperative for values education which extends beyond boundaries of personal or systemic interests and ideologies.     

On the origins of emergent differential sample behavior

Two experiments evaluated the source(s) of emergent differential sample behavior in pigeons. Initially, pigeons learned two-sample, two-alternative symbolic matching in which different patterns of sample responding were required to produce the comparisons. Afterwards, two other samples nominally identical to the comparisons were added to the matching task. On new-sample trials, completion of either sample-response requirement produced comparison alternatives which were either the same as or different from the alternatives on the familiar-sample trials. Differential responding to the new samples developed only when the comparisons were the same as the familiar samples. The results are consistent with acquired sample equivalence and adventitious reinforcement accounts of emergent sample behavior and are inconsistent with bidirectional transfer (symmetry) between the response patterns explicitly required to the originally trained (familiar) samples and the subsequently reinforced comparisons.     

Estimating state IQ: Measurement challenges and preliminary correlates

The purpose of this study is threefold. First, an estimate of state IQ is derived and its strengths and limitations are considered. To that end, an indicator of downward bias in estimating state IQ is provided. Two preliminary causal models are offered that predict state IQ. These models were found to be highly predictive of state IQ, yielding multiple R's of 0.83 and 0.89. Second, the extent to which state IQ predicts state outcome variables (e.g., gross state product, health, violent crime, and government effectiveness) is estimated. State IQ shows positive correlations with gross state product, health, and government effectiveness and negative correlations with violent crime. These results are consistent with the extent to which IQ predicts outcomes at the level of the individual. Third, a research agenda is provided for improving estimates of state IQ, identifying factors that cause differences in state IQ, and delineating the role of IQ in predicting important variables.

A comparative effectiveness trial of functional behavioral assessment methods

Clinicians report primarily using functional behavioral assessment (FBA) methods that do not include functional analyses. However, studies examining the correspondence between functional analyses and other types of FBAs have produced inconsistent results. In addition, although functional analyses are considered the gold standard, their contribution toward successful treatment compared with other FBA methods remains unclear. This comparative effectiveness study, conducted with 57 young children with autism spectrum disorder, evaluated the results of FBAs that did (n = 26) and did not (n = 31) include a functional analysis. Results of FBAs with and without functional analyses showed modest correspondence. All participants who completed functional communication training achieved successful outcomes regardless of the type of FBA conducted.
