Bridging the Gap Between the Language of Science and the Language of School Science Through the Use of Adapted Primary Literature

In this paper we make the case that the language of school science and the language of science are widely divergent. We trace the divergence to a simple view of reading that prevails not only in science education but in most of schooling. Based upon the importance of language in science and the role of language in capturing the essential nature of scientific reasoning, we conclude that conceiving of reading as a form of inquiry could assist in bringing the two languages more into alignment. We recommend the use of adapted primary literature as one curriculum and instruction innovation that can be useful in illustrating the nature of reading as inquiry.     

Supporting Teaching and Learning Using Authentic Scientific Texts: A Rejoinder to Danielle J. Ford

In her commentary Danielle J. Ford mainly focused on three issues that highlight the promises and challenges for the use of Adapted Primary Literature (APL) in science curricula: the possible contribution of APL to authentic experiences in secondary schools, implementation issues of APL including the support required for the teachers, and the possibilities to extend the use of APL to younger and older students. In this rejoinder, we first offer some general comments on Ford’s commentary. Then we offer more specific comments on two areas of her response, authenticity and the support for teachers.     

Contraction force specificity and its relationship to functional performance

Abstract

Best practice for improving strength and power through resistance strength training has been the subject of much research and subsequent conjecture. Much of the conjecture can be attributed to methodological discrepancies. The type of dynamometry used in testing, the training experience of research participants, the specific technique employed in a lift, and the methods of collection and calculation all impact on the final variables of interest. This review examines contraction force specificity by first addressing the methodological issues surrounding our interpretation of the results. Then we address the kinematics and kinetics associated with single and multiple repetitions in relation to the development of strength, power, and functional performance. This discussion provides the delimitations for analysis of subsequent training studies. Finally, recommendations are formulated with the aim of assisting assessment and training practice as well as providing directions for future research. The results of this review suggest that the enhancements in performance resulting from resistance training are context specific in experienced resistance-trained participants. Thus, specific conditioning could be required to achieve improvements in functional performance in this group.     

The role of invitations to parents in the completion of a child’s home reading challenge

The role parents can play in supporting early reading attainment is well documented. There is still, however, a need to understand what motivates parents to become involved in reading at home with their child. Past research, based upon correlational studies, has mixed findings regarding the influence of the teacher and the child on parents’ motivation at home. Through two quasi-experiments, the present study explored the influence of teacher invitations in Kindergarten classes, and child invitations in Grade 2 classes on completion rates of a home reading challenge. The completion of the home reading among families was investigated across two metropolitan schools in Sydney, Australia. Both of the interventions resulted in significantly higher completion rates compared to control groups (teacher invitations: d = .68; child invitations: d = .73). This paper adds to existing research by providing a clearer picture of the cause-and-effect relationship between schools’ use of invitations to facilitate children’s home reading.     

Our shrinking ozone layer

Depletion of the Earth’s ozone layer is one of the major environmental concerns for the new millennium having serious implications on human health, agriculture and climate. In the past decades, research by the international scientific community has been directed towards understanding the impact of human interference on the Earth’s atmosphere. The importance of ozone radiation absorption in the atmosphere and the general kinetics of the stratospheric ozone depletion mechanisms have motivated many theoretical and experimental studies on various chemical species. The distribution of ozone and other trace gases in the atmosphere is governed by the complex interaction of dynamical, chemical and radiative processes. This article concentrates on the basic concepts underlying the problems that may be faced by humankind due to reduction in the ozone layer in coming decades, and the ways in which the scientific community can contribute to predicting and remediating these effects through design of international treaties, regulations and amendments.
