Selective habituation of defensive behavior: Evidence for predator-prey synchrony

The selective nocturnal persistence of death feigning, an antipredator behavior, was assessed in four studies involving single daily trials. In Experiments 1 and 2, White Leghorn chicks exhibited a progressive decline in death feigning durations in both the light and the dark phases of their photoperiods over 8 days, but resistance to habituation was greater at night. When nocturnal death feigning was induced to a habituation criterion (Experiment 3), it was extremely persistent and was not completely abolished in some chicks, even after 25 consecutive test days. Because nocturnal response durations of chicks tested cross-sectionally increased over the same developmental period (Experiment 4), a shifting developmental baseline was excluded as the basis for the declining response durations observed in the first three studies. The differential plasticity of death feigning at two times of day is consistent with the argument that predatorprey synchrony confers a selective advantage, and suggests an additional biological constraint on learning.

Conceptualization and Measurement of Cognitive Holding Power

The concept of cognitive holding power is synthesized from theories of settings and of cognitive structures and is conceptualized as a characteristic of a learning setting that presses students into different kinds of cognitive activity. Settings which press students into using first- or second-order cognitive procedures are regarded as having first- or second-order cognitive holding power. The development of an instrument to measure these two dimensions of cognitive holding power is outlined. The independence of the dimensions, their reliabilities and validity, and factor structures are examined. Each dimension was found to have high reliability across vocational education and high school settings, and each was correlated as predicted with other classroom variables. The potential contribution of this research to understanding the relationship between different approaches to the teaching of problem solving and the ability to undertake problem-solving transfer tasks is outlined.     

Facebook class groups of high school students: their role in establishing social dynamics and learning experiences

The study’s main aim was to explore the role of Facebook class groups, created and managed by high-school students, in facilitating social dynamics and learning experiences. Fourteen Facebook class groups were observed online and students were subsequently questioned through focus-group interviews. Our findings show that Facebook class groups can promote both bonding and learning. Bonding can be enhanced because Facebook class groups foster a sense of solidarity and unity among students. Also, Facebook can stimulate (social) learning because students gain more insights in the subject matter and are challenged to carry out an evaluation of their own study methods and progress. Therefore, drawing on the theories of seamless learning and affinity spaces, we conclude that Facebook class groups are important for social affiliation and effective learning.

     

EXAMINING POTENTIAL BIAS IN SCREENING MEASURES FOR MIDDLE SCHOOL STUDENTS BY SPECIAL EDUCATION AND LOW SOCIOECONOMIC STATUS SUBGROUPS

To provide timely and effective supports for students reading below grade level, schools require methods for quickly and accurately identifying those students in need. One method for identifying those students is through universal screening. Assessments such as oral reading fluency (ORF) and Maze reading comprehension are commonly used as screening assessments in middle grades. The current study examined ORF and Maze for evidence of bias across two subgroups known to be at increased risk for failure in reading: (a) students with learning disabilities and (b) students from low‐income households. Data from 4,215 students in the sixth (n = 1,126), seventh (n = 1,361), and eighth grades (n = 1,728) were analyzed. Results indicate no significant differences in predictive validity for students from low‐income households compared to students from middle and upper income households. For students with learning disabilities only 8th grade scores showed any evidence of bias compared to students without diagnosed disabilities. Implications and recommendations for future research are discussed.     

Time Use and Mathematics Achievement among American, Chinese, and Japanese High School Students

Cultural differences in the structure of adolescents' daily lives were examined by interviewing representative samples of 578 grade 11 students, aged 16–17 years, in Minneapolis, Taipei (Taiwan), and Sendai (Japan) about the amounts of time they spent in a wide variety of activities. Studying, interacting with peers, and watching television were the most frequent activities in all 3 locations, but the relative importance of each activity differed among the locations. Chinese students spent significantly more time than American students engaged in academic endeavors, such as attending school and after-school classes and studying. Japanese students did not spend significantly more time studying or attending after-school classes than American students, but they did spend more time attending school. American students, in turn, spent more time working and socializing with friends. Differences in adolescents' use of time were related to both cross-cultural and individual differences in mathematics achievement.     

Creating Communities of Shared Practice: The challenges of assessment use in learning and teaching

Teachers and researchers in the field of educational assessment have a strong professional interest in evaluating practices that constitute effective educational assessment at the classroom level. In pursuing these goals it is fundamental for teachers and pupils to grow in a community of shared practice where nothing in the assessment process is hidden and students become assessors of their own learning. The challenge for students and teachers within present-day classrooms is understanding and learning how these communities are created. This paper is based on action research carried out to investigate our own teaching of the subject of assessment at postgraduate level. The focus of the research was to integrate current research evidence within educational assessment into our own professional practice. Such research suggests that to improve learning and indeed teaching, educational assessment must be formative in both function and purpose and must put the student at the centre of the assessment process. The paper describes the processes and procedures by which common meanings of published criteria and assessment quality for masters level coursework held by one community of assessors were shared and interpreted by students to enable them to articulate their own learning through student-self assessment.     

Mathematics Achievement of Children in China and the United States

First and fifth graders in Beijing and Chicago were given a battery of mathematics test. Whether tested with problems requiring solely computation or with ones requiring application of knowledge about mathematics, American children's performance was consistently inferior to that of Chinese children. Interviews with American children suggested that they like mathematics, believe they are doing well in mathematics, and do not perceive mathematics as a difficult subject. American children's poor performance appears to be attributable, in part, to low motivation for devoting more attention to mathematics. Low standards held by American parents for academic achievement and lower interest in teaching mathematics by American teachers appear to contribute to American children's poor performance.
