IQ and neuropsychological predictors of academic achievement

Word reading and math computation scores were predicted from Wechsler Abbreviated Scale of Intelligence Full Scale IQ, 10 neuropsychological tests, and parent attention deficit hyperactivity disorder (ADHD) ratings in 214 general population elementary school children. IQ was the best single predictor of achievement. In addition, Digit Span contributed significantly to reading prediction, and the Developmental Test of Visual-Motor Integration (VMI) and Coding contributed to math prediction. The remaining neuropsychological test scores did not significantly improve achievement prediction. Exploratory factor analysis yielded a general ability factor (comprising the four IQ subtests, Digit Span, VMI, reading, and math), five factors made up solely of subtests from single measures (Wisconsin Card Sorting Test, Stroop Color and Word Test, Gordon Diagnostic System, California Verbal Learning Test, and ADHD ratings), a factor consisting of Grooved Pegboard Test and Coding, and a factor consisting of Symbol Search and Animal Naming Test.     

Spoken language development in oral preschool children with permanent childhood deafness

This article documented spoken language outcomes for preschool children with hearing loss and examined the relationships between language abilities and characteristics of children such as degree of hearing loss, cognitive abilities, age at entry to early intervention, and parent involvement in children's intervention programs. Participants were evaluated using a combination of the Child Development Inventory, the Peabody Picture Vocabulary Test, and the Preschool Clinical Evaluation of Language Fundamentals depending on their age at the time of assessment. Maternal education, cognitive ability, and family involvement were also measured. Over half of the children who participated in this study had poor language outcomes overall. No significant differences were found in language outcomes on any of the measures for children who were diagnosed early and those diagnosed later. Multiple regression analyses showed that family participation, degree of hearing loss, and cognitive ability significantly predicted language outcomes and together accounted for almost 60% of the variance in scores. This article highlights the importance of family participation in intervention programs to enable children to achieve optimal language outcomes. Further work may clarify the effects of early diagnosis on language outcomes for preschool children.     

Writing and Reading Subjects: Fixing and Unfixing Identity through Close Literary Practices

For a number of years, Rebecca Luce‐Kapler and Dennis Sumara have been investigating the ways in which literary practices of close reading can help change how we think and how we remember. They have also considered how such practices might help make us more critical of normative representations of remembered experience. More recently, they have been joined by Claire Robson, who works with and investigates memoir writing. In 2009, Robson and Sumara were joined by their six older lesbian research participants at a conference held at the University of British Columbia entitled ‘Queerly Canadian: Changing Narratives’. The six women performed extracts from memoirs they had written as part of the research data and joined the researchers in offering theories and insights about the writing processes in which the group had engaged. That presentation and this paper represent the evolution of a two‐year collaboration between these researchers and the six women, who are listed as co‐authors on both the presentation and this paper.     

The effective teaching of comparing Orff music method with traditional music approach for music reading and melodic patterns singing for 3rd grade elementary students in Taiwan

The Orff music method has been internationally practiced and recognized as one of the leading music methods in the past fifty years. The success of this approach is that this method encourages all students participating in the designed music activities in the music class to interact with the teacher and other classmates using the Orff approach rather than the traditional one-way music learning approach in the traditional music classroom in Asia. While the children are situated within an environment where music activities and bodily movements are stimulated, the children＇s aesthetic music knowledge can be influenced significantly （Carlson, 1990）. In this study, there were a total number of 180 3rd graders from three elementary schools in Taiwan who participated in this research. The control group which consisted of three classes with a total number of 90 students was the class using the traditional music method taught by a regular classroom teacher, while the experimental group, which consisted of another three classes with a total number of 90 students, was the class taught using the Orff music method by the researcher. The study was controlled in the sense that the six music classes were ascertained to be of equal ability in their understanding of music before the experimental factor was applied. As well, there were no significant differences in age or mental capacity, while the difference in genders was only minimal. The results of this research revealed that not only did the students who had the Orff music method training perform better than the traditional music method on both melodic patterns dictation and music reading tests, but the Orff training also helped the experimental students to have a solid understanding of rhythmic structures and basic music knowledge.     

Investigating Strategies for Pre-Class Content Learning in a Flipped Classroom

In a flipped classroom model, learning of basic content is shifted before class while in-class time is used for concept application. Empirical and controlled research studies are lacking on the best strategies to provide the necessary pre-class content instruction. In this study, we tested three methods of pre-class content learning—interactive online tutorials, video lectures, and textbook-style readings—while holding the content and the in-class application activities constant. Identical introductory, non-majors biology classes were manipulated at both a public, open-enrollment institution and a private, highly selective institution. We found that video lectures offer a small advantage to overall student learning over interactive tutorials or textbook-style readings. Although our two populations differed in their ability to effectively learn from pre-class activities, through a student-centered flipped classroom approach, students at both institutions demonstrated equal learning gains by the final assessment. Potential reasons for some observed differences are suggested.     

Comment on ‘Ventilation and blood lactate increase exponentially during incremental exercise’ : A reply

Oar force and oar angle data resulting from a 6‐min maximal rowing ergometer test undertaken by novice (n = 9), good (n ‐ 23) and national (n = 9) level male rowers, were used to identify biomechanical performance variables which accurately discriminated between rowers of differing ability levels. The variables included two work capacity measures, mean propulsive power output per kilogram of body mass (W kg^‐1) and propulsive work consistency (%), and two skill variables, stroke‐to‐stroke consistency (%) and stroke smoothness (%). Discriminant function analysis indicated the presence of two functions, both of which clearly indicated the importance of mean propulsive power output per kilogram of body mass as a discriminating variable. Function 2 gave greater weight to stroke‐to‐stroke consistency and stroke smoothness than function 1; however, function 1 was the most powerful discriminator. Classification procedures were used to predict the ability level to which a rower most likely belonged and involved defining the ‘distance’ between each rower and each ability level centroid, with the rower being classified into the ‘nearest’ ability level. These procedures indicated that 100% of the elite, 73.9% of the good, 88.9% of the novice and 82.9% of all rowers were correctly classified into their respective skill levels. Stepwise discriminant analysis included the variables in the following order: mean propulsive power output per kilogram of body mass, stroke‐to‐stroke consistency, stroke smoothness and propulsive work consistency (P < 0.001). The results of this study indicate that biomechanical performance variables related to rowing capacity and skill may be identified and used to discriminate accurately between rowers of differing skill levels, and that, of these variables, propulsive work consistency is the least effective discriminator.
