Sex differences in self‐estimation of multiple intelligences among Portuguese adolescents

This study investigated the relationship among sex, attitude toward intelligence, and self‐estimation of multiple intelligences for self and parents among Portuguese adolescents in secondary schools. Two hundred and forty‐two adolescents estimated their own and their parents' IQ scores on each of Gardner's 10 multiple intelligences: verbal (linguistic), logical (mathematical), spatial, musical, body‐kinesthetic, interpersonal, intrapersonal, existential, spiritual, and naturalistic. They also answered six simple questions concerning intelligence and intelligence tests. There were various sex differences in self‐estimated IQ: males rated themselves higher on overall, mathematical, spatial, intrapersonal, spiritual, and naturalistic IQ compared with females. Multiple regressions indicated that verbal, logical, and intrapersonal intelligence were significant predictors for self and parents overall IQ estimations. Factor analysis of the 10, the 8, and the 7 self‐estimates scores did not confirm Gardner's classification of multiple intelligences. Males were more likely to believe in sex differences in intelligence than females. Results are discussed in terms of the growing literature in the self‐estimates of intelligence, as well as limitations of that approach.

Assessment using the P scales: best fit – fit for the purpose?

In this article, Andrew Martin, deputy headteacher at Greenside School in Stevenage, provides an outline of the development of the P scales as an assessment tool for pupils working below Level 1 of the National Curriculum. He recounts the difficulties his school found in using P scales to track pupil progress from year to year and describes and evaluates a computer package which he devised in order to fulfil this function. He goes on to discuss current issues in the use of P scales, many of which were highlighted through use of the computer package. These issues include inconsistency in the use of the P scales; variations in pupil profiles; difficulties over making 'best fit' judgements; the need for moderation; and relationships with other curriculum and assessment systems in the school years and in the Foundation Stage. Andrew Martin closes his article with a call for consistency in approaches to assessment, particularly in view of the fact that P scale assessments are to be collected as part of statutory end of key stage data collection arrangements in future.     

优势分析:确定回归方程预测指标相对重要性的统计方法

确定多元回归方程中各预测指标相对重要性的传统方法具有模型依赖性特征 ,无法在多元回归模型衍生出的不同子模型中使相对重要性指标保持恒定不变。 Budescu(1993)近来提出的优势分析 ,则克服了上述缺点。优势分析将各预测指标对因变量总方差的贡献分解为已预测方差百分比 ,从而使各预测指标的相对重要性得以更精确地表现出来 ;同时 ,优势分析产生的各预测指标的已预测方差百分比还具有模型独立性特征 ,不受多元回归模型中不同预测指标不同组合的影响。通过运动员生活满意感的一个研究实例讨论了优势分析的操作过程、统计意义和应用前景。
