Re-imaging and re-constructing cross-cultural research through critical personal narratives: an examination into fault lines

In this paper, the authors illustrate the impacts of their cross-cultural research in Africa, on their current work in science and STEM education. Through the examination of two research projects in cross-cultural settings in Africa, the authors explore the lasting impacts of this type of work. Specifically, through the use of Critical Personal Narratives and feminist theory, the authors discover fault lines existing in this cross-cultural work and ultimately the shifts in their conceptions of science and STEM education.     

Concept mapping,vee mapping,and achievement: Results of a field study with black high school students

This article reports on the results of a project that studied the effectiveness of two specific learning heuristics, concept mapping and Vee mapping, in helping black, inner-city, high school students learn biology concepts meaningfully. The project sought to assess the effects on achievement of the use of these two heuristics as part of a carefully designed sequence of instruction. Two instructional treatments were compared, one that utilized the two experimental heuristics as study aids and one that utilized outlining as a comparison study aid. The instructional treatments were administered over approximately a one semester period. Two hundred and fifty subjects, nearly all black, from two urban high schools in Indiana took part in the study. Achievement instruments designed to measure meaningful (higher order) learning were developed. Analysis of variance of the achievement test means failed to reveal statistically significant differences between the experimental and comparison treatment at the 0.05 alpha level. However, there were suggestions of a tendency toward an effect of the experimental treatment, and several factors contributing to the difficulty in distinguishing achievement differences were identified.     

Teaching and Learning Nature of Science in Elementary Classrooms

Science & Education - Our goal in this article is to provide research-based strategies for embedding Nature of Science (NOS) into science instruction at the elementary level. We thus intend to...     

Multivariate alternatives to regression analysis in the evaluation of salary equity-parity

The analysis of salary equity-parity in institutions of higher education typically involves the use of multiple regression analysis to determine predicted salary and the residual differences between predicted and actual salary. Multiple regression analysis forces the variable weights throughout the salary structure to be uniform, permits only one criterion or dependent variable to be examined at a time, restricts the coordinates to those provided by the variables as measured, and as customarily used, treats qualitative or discrete variables as if they were continuous, assuming ordinality of the numbers used. Two multivariate alternatives to regression analysis are presented, canonical analysis and multiple discriminant analysis, both of which define new coordinate systems for evaluation of dimensions underlying salary decisions.Presented at the 23rd Annual Forum of the Association for Institutional Research, Toronto, May 1983.     

Investigatory behavior inthe plains garter snake (Thamnophis radix) and several additional species

Garter snakes (Thamnophis radix), hognose snakes (Heterodon platyrhinos), and rattlesnakes (Crotalus species) flick their tongues and crawl about in an open field containing no food or sexual (i.e., reproductive) odors. As Experiment I shows, the taxa differ reliably in both rate of tongue flicking and rate of locomotion. In Experiment II, garter snakes (Thamnophis radix) placed into an open field for 5 min showed more tongue flicking than snakes that were handled and placed directly back into their home cages, indicating that the first group was exploring the apparatus rather than responding only to handling. During Minutes 3 through 5 (Experiment III) in the open field, garter snakes emitted fewer tongue flicks than they did during the first minute, and after 20 min, the rate of tongue flicking was virtually zero. However, snakes were capable of responding to presentation of new objects and/or odors, indicating that the previous response decrement was not derived from effector fatigue but rather from some habituatory process. Experiment IV revealed that satiated snakes habituated more rapidly than hungry snakes during exploration of the open field. Hence, exploratory behavior in these snakes is at least partially under the control of the same factors which mediate food-related appetitive activities.     

Whiplash shaking syndrome: retinal hemorrhages and computerized axial tomography of the brain

Three cases of whiplash shaking injury of infants are presented. All children presented with seizures and had minimal signs of external injury. Examination of the retina revealed extensive retinal hemorrhages. These were missed on initial examination and were only discovered after pupillary dilatation. The presence of these palecentered retinal hemorrhages suggested the diagnosis of child abuse and skeletal surveys and thorough social histories confirmed the diagnosis. Despite extensive retinal hemorrhages, computerized axial tomography (C.T.) scan showed minimal inter-hemispheric bleeding. In contrast to the "Battered Child Syndrome," all the findings in whiplash shaking syndrome of infants are subtle and demand an awareness, an index of suspicion and a thorough examination which may include extensive retinal examination following dilatation of the pupils. This latter examination is frequently not performed by family physicians and residents so that the syndrome may be missed. A fourth case is also discussed where shaking is admitted on initial presentation but said to be done for resuscitation. This poses an immense diagnostic dilemma to the pediatrician since in this case the child presented later with all the signs of physical abuse.     

A Pedagogy of Friendship: young children’s friendships and how schools can support them

Children’s friendships are often neglected by teachers and researchers. This phenomenological study conducted with seven children aged five and six years explores young children’s perceptions of their everyday friendship experiences. This multi-method study used role play interviews, drawings and persona doll scenarios to consider children’s everyday experiences of friendship in school. The paper discusses the importance of socio-cultural aspects of children’s friendship including: imaginary friends; losing friends; protecting time and space to develop friendships and children’s routines and practices as they form and maintain friendships. Data and findings are discussed, leading to an original conceptual framework: a ‘Pedagogy of Friendship’. This is designed to help children make meaning from their friendship experiences and also provide practitioners with the opportunity to nurture and scaffold children through their friendship experiences in schools. We suggest that there is a need to raise the profile of children’s friendships in early childhood education and generate an educational perspective on friendship. Finally we conclude that listening to children’s views of friendship indicates that the application of the framework of a ‘Pedagogy of Friendship’ would be beneficial to children’s all round learning and development.
