Inter- and intra-individual differences in teachers' self-efficacy: A multilevel factor exploration

This study explored inter- and intra-individual differences in teachers' self-efficacy (TSE) by adapting Tschannen-Moran and Woolfolk Hoy's (2001) Teachers' Sense of Efficacy Scale (TSES) to the domain- and student-specific level. Multilevel structural equation modeling was used to evaluate the factor structure underlying this adapted instrument, and to test for violations of measurement invariance over clusters. Results from 841 third- to sixth-grade students and their 107 teachers supported the existence of one higher-order factor (Overall TSE) and four lower-order factors (Instructional Strategies, Behavior Management, Student Engagement, and Emotional Support) at both the between- and within-teacher level. In this factor model, intra-individual differences in TSE were generally larger than inter-individual differences. Additionally, the presence of cluster bias in 18 of 24 items suggested that the unique domains of student-specific TSE at the between-teacher level cannot merely be perceived as the within-teacher level factors' aggregates. These findings underscore the importance of further investigating TSE in relation to teacher, student, and classroom characteristics.     

Comparison of Hispanic children with and without limited English proficiency on the Naglieri Nonverbal Ability Test

Hispanic children with (n=148) and without (n=148) limited English proficiency were given the Naglieri Nonverbal Ability Test (NNAT; J. A. Naglieri. 1997a) and the Stanford Achievement Test-9th edition (SAT-9: 1995). The groups were selected from the NNAT standardization sample (N=22.620) and matched on geographic region, gender, socioeconomic status, urbanicity. and ethnicity. There was a very small difference (d ratio=0.1) between the NNAT standard scores for the children with limited English proficiency (M - 98.0) and those without limited English proficiency (M=96.7). The NNAT correlated moderately and similarly with achievement for the 2 groups. The sample of children with limited English proficiency earned considerably lower scores on SAT-9 Reading and Verbal subtests. Results suggest that the NNAT may be useful for the assessment of Hispanic children with and without limited English proficiency.     

A Statistical Correction to 20 years of Banding

Statistically based banding is often considered a viable method for minimizing adverse impact in test‐based employment decisions. By utilizing the standard error of the difference (SED), scores are equated based on the assumption that there is substantial unreliability in any single observed score. However, based on the derivations of Dudek, the formula commonly used to calculate the standard error of measurement (SEM) – a component that is typically used to calculate the SED – is incorrect. Specifically, utilizing the SEM when calculating the SED produces a band of observed scores around a true score, not a band of true scores around an observed score as would be appropriate for banding. This study compares the differences between banding‐based selection decisions when the appropriate SED formula – which utilizes the standard error of estimate – is and is not applied. Overall, results suggest that utilizing the appropriate formula for calculating the SED produces substantial variations in employment decisions. The potential legal and ethical implications of these discrepancies are discussed.     

Hyperactive behavior in english schoolchildren: A questionnaire survey

The differences in apparent prevalence of childhood hyperactivity between England and North America are more than 20-fold. This paper seeks to illuminate the reasons for the difference by applying a standard measure [Conners Teacher Rating Scale] to 437 English schoolchildren, aged 6 to 9 years, and comparing them with published surveys from the United States and Australasia. The rating scale had moderate interrater reliability and stability over time; it distinguished between children referred for psychiatric treatment and normal schoolchildren. Component analysis yielded a factor of hyperactivity-inattentiveness, distinct from conduct disorder. The mean hyperactivity scores of English children were higher than in most U.S. surveys but lower than in New Zealand. The national differences in rates of diagnosed hyperactivity are likely to reflect diagnostic inconsistency rather than true differences in children's behavior.     

Thresholds for color discrimination in English and Korean speakers

Categorical perception (CP) is said to occur when a continuum of equally spaced physical changes is perceived as unequally spaced as a function of category membership (Harnad, S. (Ed.) (1987). Psychophysical and cognitive aspects of categorical perception: A critical overview. Cambridge: Cambridge University Press). A common suggestion is that CP for color arises because perception is qualitatively distorted when we learn to categorize a dimension. Contrary to this view, we here report that English speakers show no evidence of lowered discrimination thresholds at the boundaries between blue and green categories even though CP is found at these boundaries in a supra-threshold task. Furthermore, there is no evidence of different discrimination thresholds between individuals from two language groups (English and Korean) who use different color terminology in the blue-green region and have different supra-threshold boundaries. Our participants’ just noticeable difference (JND) thresholds suggest that they retain a smooth continuum of perceptual space that is not warped by stretching at category boundaries or by within-category compression. At least for the domain of color, categorical perception appears to be a categorical, but not a perceptual phenomenon.     

Personality Factors Related to Black Teenage Pregnancy and Abortion

Forty-eight pregnant adolescents who applied for therapeutic abortions (TAs) were compared with 55 adolescents who planned to have their babies (Terms) and 67 adolescents who were not pregnant (Controls) on the California Psychological Inventory (CPI). All the subjects were single, Black, and aged 15 or 16. CPI results point to psychological differences with the Controls being most socialized, followed by the TAs, and then the Terms. Term girls seem to be experiencing a void and appear to be trying to fill it and assume an adult role by having a baby; the TAs do not seem to have these same needs. In addition, girls who became pregnant and described the relationship with the putative father as casual, appear on the CPI to have more daily problems, lack socialization, be less clear thinking, and have poor self-control. Pregnant girls who have good communication with their mothers showed no differences on the CPI from girls with poor communication with their mothers.     

A longitudinal study of bilingual and cognitive development(1)

This paper presents the findings of a longitudinal study of IQ data collected over a 5-year period (Grades K-4) on pupils enrolled in a French immersion program (anglophone pupils receiving all instruction in French except English language arts) and pupils in the regular English program. Although year-by-year results may fail to show IQ differences between the two groups, repeated measures analysis indicates that the immersion group has a higher IQ measure over the 5-year period. However, considering Grades 1–3 only, which involved the administration of the same test, the two groups do not score differentially with respect to either overall IQ measure or specific subtest scores (classification/categorization, analogies, following of verbal directions) when scores are adjusted for initial IQ (and age) differences, thus failing initially to support studies which show positive relationships between bilingualism and cognitive functioning. However, supportive of those studies is a further analysis on the data of immersion pupils classified as “high” French achievers vs. “low” French achievers. The high French achievers obtain significantly higher IQ measures and subtest scores (analogies and following of verbal directions) than the low French achievers, even when scores are adjusted for initial IQ and age differences. These findings are interpreted in the context of Cummins' (1976) “threshold” hypothesis relating to level of competence in the second language.     

Individual differences make a difference: On the use and the psychometric properties of difference scores in social psychology

Much social psychological research is concerned with the question whether and how behavior changes because of a “treatment” (e.g., a situation that triggers a psychological reaction). One easy way to investigate such changes would be to analyze intraindividual differences before (Time 1) and after the treatment (Time 2). Interestingly, many scholars refrain from using difference scores because they think they are inherently unreliable. However, the bad reputation of difference scores is, in many cases, unwarranted: difference scores can be sufficiently reliable when standard deviations differ between measurement occasions, and standard deviations are likely to differ between measurement occasions because of differential treatment effects (i.e., interindividual differences in responsiveness to a treatment) and/or “strong situation” treatments. In the present article, we will (1) summarize classic and current arguments regarding the reliability of difference scores, (2) discuss the use of residual change scores as an alternative to difference scores, and (3) argue that latent difference score models are a particularly useful tool that social psychologists should consider using more frequently.

非英语专业大学生CET4成绩影响因素的结构模型

以501名参加过CET4的非英语专业大学生为研究对象,通过英语自我效能感问卷（ESEQ）、英语学习焦虑量表（ELAS）和英语学习策略量表（ELSI）的测量,探讨CET4成绩与其主要影响因素性别、英语自我效能感、英语学习焦虑和英语学习策略之间的结构关系模型。结果显示：（1）非英语专业大学生的英语学习焦虑存在显著的性别差异（女生低于男生）;（2）性别除与英语学习策略不存在直接路径作用外,与CET4成绩、英语自我效能感、英语学习焦虑间均存在直接路径作用;（3）英语学习焦虑对CET4成绩既存在直接路径作用,又通过英语自我效能感、英语学习策略和英语自我效能感的中介产生问接路径作用;（4）英语学习策略仅通过英语自我效能感的中介对CET4成绩产生间接路径作用。研究还表明英语自我效能感在CET4成绩影响因素的结构模型中起着瓶颈作用。     

Personality factors related to black teenage pregnancy and abortion

48 pregnant adolescents who applied for therapeutic abortions (TAs) were compared with 55 adolescents who planned to have their babies (Terms) and 67 adolescents who were not pregnant (Controls) on the California Psychological Inventory (CPI). All the subjects were single, black, and ages 15-16. CPI results point to psychological differences with the Controls being most socialized, followed by the TAs, and then the Terms. Term girls seem to be experiencing a void and appear to be trying to fill it by assuming an adult role and having a baby; the TAs do not seem to have these same needs. In addition, those girls who became pregnant and described the relationship with the putative father as casual, appear on the CPI to have more daily problems, lack socialization, be less clear thinking, and have poor self-control. Pregnant girls who have good communication with their mothers showed no differences on the CPI from girls with poor communication with their mothers.     

Normative Data for the Boston Naming Test in Native Dutch-Speaking Belgian Elderly

A normative study of the 60-item version of the Boston Naming Test (BNT) was performed in a group of 200 native Dutch-speaking Flemish elderly. Analysis of test results revealed that BNT performance in Dutch is significantly affected by age, years of education, and gender. Error analysis disclosed verbal semantic paraphasias to occur as the most frequent error type (1/3 errors). “Don't know responses,” verbal semantic paraphasias, and adequate circumlocutions were found on at least 30 different BNT items and constituted the most diffusely distributed error types. Following a careful review of other normative BNT studies, group characteristics rather than cultural differences were found to account for the difference in the overall mean scores. Our study surprisingly revealed that, as far as American–English, Australian–English and Dutch-speaking elderly are concerned, linguistics do not have an impact on the overall mean BNT score. A linguistic impact, however, clearly holds on the qualitative levels of performance, reflected by fundamental differences in the error distribution in different languages. Language-related BNT characteristics therefore stress the need for specific adaptations of norms.     

Minimizing error in measurement of error: a proposed method for calculation of error in a two-dimensional motor task

Traditional one-dimensional error scores are still consistently used in research on motor learning to quantify two-dimensional error; however, the inherent differences in two-dimensional tasks render that application inappropriate and often misleading. Consequently, the purpose of this paper was to propose a novel method of presenting errors, which more precisely represents the accuracy, direction, and variability of error in two-dimensional settings. Although closely related to several alternatives for representing errors, the methodology used and the results obtained provide a more accurate procedure for pinpointing critical trends in what have been commonly referred to as AE (absolute error), VE (variable error), CE (constant error), and E (total variability). The proposed measurements of AVE (adjusted variable error), DE (directional error), TSE (total spread of error), and RE (radial error) provide composite error scores carrying a variety of information about performance on two-dimensional tasks. Formulas and examples are provided to facilitate computation and enhance understanding of the proposed scores.

A new Visual Aesthetic Sensitivity Test (VAST): II. cross-cultural comparison between England and Japan

A comparison was made of the scores of 171 Japanese boys and 156 Japanese girls, and of 204 English boys and 165 English girls, on the Visual Aesthetic Sensitivity Test. Also compared were 145 male and 163 female Japanese students, with 38 male and 73 female English students. Japanese children had scores significantly higher than English children, while Japanese students had scores significantly lower than English students. There was little evidence of age increments in score for either group of children. Difficulty levels of the 42 item-pairs were very similar in the two cultures, as were internal (split-half) reliabilities. It is concluded that cultural differences between the two countries, as far as visual aesthetic appreciation is concerned, seem at best minimal.     

The word frequency effect in first- and second-language word recognition: A lexical entrenchment account

We investigate the origin of differences in the word frequency effect between native speakers and second-language speakers. In a large-scale analysis of English word identification times we find that group-level differences are fully accounted for by the individual language proficiency scores. Furthermore, exactly the same quantitative relation between word frequency and proficiency is found for monolinguals and three different bilingual populations (Dutch–English, French–English, and German–English). We conclude that the larger frequency effects for second-language processing than for native-language processing can be explained by within-language characteristics and thus need not be the consequence of “being bilingual” (i.e., a qualitative difference). More specifically, we argue that language proficiency increases lexical entrenchment, which leads to a reduced frequency effect, irrespective of bilingualism, language dominance, and language similarity.     

Examining the reliability of interval level data using root mean square differences and concordance correlation coefficients

This article introduces new statistics for evaluating score consistency. Psychologists usually use correlations to measure the degree of linear relationship between 2 sets of scores, ignoring differences in means and standard deviations. In medicine, biology, chemistry, and physics, a more stringent criterion is often used: the extent to which scores are identically equal. For each test taker (or other unit of measurement), the difference between the 2 scores is calculated. The root mean square difference (RMSD) represents the average change from 1 set of scores to the other, and the concordance correlation coefficient (CCC) rescales this coefficient to have a maximum value of 1. This article shows the relationship of the RMSD and CCC to the intraclass correlation coefficients, product-moment correlation, and standard error of measurement. Finally, this article adapts the RMSD and the CCC for linear, consistency, and absolute definitions of agreement.     

Beyond the broom cupboard: teaching assistants’ reflections upon the wider impact of their specialist dyslexia training

Whilst the government-commissioned Rose Report (2009) on provision and support for dyslexic learners in England called for the deployment of more specialist dyslexia teachers in mainstream schools, the reality seems to be that the job of teaching literacy to children with dyslexia is falling to teaching assistants (TAs). As a result, specialist training courses for TAs have been developed in England. Using the Coldwell and Simkins Training Impact Framework, the present study examines TAs participants’ perceptions of the impact of two such local authority-based training programmes, not just in terms of the impact upon their individual practice, but also in terms of their perceptions of the wider impact of their status as a trained ‘expert’ upon their schools’ policies, culture and practice. ‘Enabling’ and ‘blocking’ factors influencing this wider impact are identified, and implications for the deployment of specialist TAs and the design of their training courses are discussed.     

TESTICULAR SELF-EXAMINATION: VALIDATION OF A TRAINING STRATEGY FOR EARLY CANCER DETECTION

Testicular self-examination (TSE) can lead to early diagnosis and treatment of testicular cancer, the third leading cause of death in young men. We evaluated the effectiveness of a brief and specific checklist for teaching TSE skills. Ten men were videotaped while performing testicular self-examinations before and after training. The TSE training resulted in large and significant increases in the number of TSE steps completed and duration of the TSE. Two urological validation measures supported the improvements observed in the mens' self-examinations. Subjects reported continued performance of TSE during a follow-up telephone interview. This pilot study indicates that a brief and specific checklist is an effective strategy for teaching early cancer detection skills.     

National differences in personality; Brazil and England

The Eysenck Personality Questionnaire (E.P.Q.) was used to compare the structure of personality in Brazilian and English men and women, and to compare the mean scores of these population on the test. Six hundred and thirty six male and 760 female Brazilian adults were compared with 500 English males and 500 English females. It was found that identical factors appeared in the Brazilian as had been discovered in the English populations, and that intercorrelations of scales, reliabilities, etc. were similar for the two populations. Some items from the original study were found inapplicable in Brazil, and new items were substituted. A comparison of the mean scores of the two populations on a reduced scale, embodying only those items which were valid for both populations, showed that there were very few differences between the populations.     

Sex differences in Cognitive Abilities Test scores: A UK national picture

Background and aims. There is uncertainty about the extent or even existence of sex differences in the mean and variability of reasoning test scores ( Jensen, 1998 ; Lynn, 1994, 1998 ; Mackintosh, 1996 ). This paper analyses the Cognitive Abilities Test (CAT) scores of a large and representative sample of UK pupils to determine the extent of any sex differences. Sample. A nationally representative UK sample of over 320,000 school pupils aged 11–12 years was assessed on the CAT (third edition) between September 2001 and August 2003. The CAT includes separate nationally standardized tests for verbal, quantitative, and non‐verbal reasoning. The size and recency of the sample is unprecedented in research on this issue. Methods. The sheer size of the sample ensures that any sex difference will achieve statistical significance. Therefore, effect sizes (d) and variance ratios (VR) are employed to evaluate the magnitude of sex differences in mean scores and in score variability, respectively. Results. The mean verbal reasoning score for girls was 2.2 standard score points higher than the mean for boys, but only 0.3 standard points in favour of girls for non‐verbal reasoning (NVR), and 0.7 points in favour of boys for quantitative reasoning (QR). However, for all three tests there were substantial sex differences in the standard deviation of scores, with greater variance among boys. Boys were over represented relative to girls at both the top and the bottom extremes for all tests, with the exception of the top 10% in verbal reasoning. Conclusions. Given the small differences in means, explanations for sex differences in wider domains such examination attainment at age 16 need to look beyond conceptions of ‘ability’. Boys tend to be both the lowest and the highest performers in terms of their reasoning abilities, which warns against the danger of stereotyping boys as low achievers.
