From scientific practice to high school science classrooms: Transfer of scientific technologies and realizations of authentic inquiry

The Biology Workbench (BW) is a web‐based tool enabling scientists to search a wide array of protein and nucleic acid sequence databases with integrated access to a variety of analysis and modeling tools. The present study examined the development of this scientific tool and its consequent adoption into the context of high school science teaching in the form of the Biology Student Workbench (BSW). Participants included scientists, programmers, science educators, and science teachers who played key roles along the pathway of the design and development of BW, and/or the adaptation and implementation of BSW in high school science classrooms. Participants also included four teachers who, with their students, continue to use BSW. Data sources included interviews, classroom observations, and relevant artifacts. Contrary to what often is advocated as a major benefit accruing from the integration of authentic scientific tools into precollege science teaching, classroom enactments of BSW lacked elements of inquiry and were teacher‐centered with prescribed convergent activities. Students mostly were preoccupied with following instructions and a focus on science content. The desired and actual realizations of BSW fell on two extremes that reflected the disparity between scientists' and educators' views on science, inquiry science teaching, and the related roles of technological tools. Research on large‐scale adoptions of technological tools into precollege science classrooms needs to expand beyond its current focus on teacher knowledge, skills, beliefs, and practices to examine the role of the scientists, researchers, and teacher educators who often are involved in such adoptions. © 2010 Wiley Periodicals, Inc.

A Quick,Accurate, and Free-of-Cost Inventory and Shelf-Reading Solution

This article presents a solution that was used at Notre Dame University–Louaize (NDU) Library, Lebanon, to conduct efficient, accurate, and low-cost inventory and shelf reading. By exporting catalog records into an Excel spreadsheet and using nested formulas to compare records exported from the online library system against the books existing on the shelves, the inventory was successfully completed in a manageable time period. This simple solution, using a laptop and a handheld bar code reader, significantly reduced the number of staff and the amount of time required to perform the inventory. It also greatly reduced human error and inconsistencies faced in previously conducted inventories while helping to maintain staff concentration and enthusiasm for the project.     

Constructing a professional development school: A model of one school‐university partnership

Abstract

A partnership between an elementary school and a university in the Midwest evolved into a professional development school. The authors describe this process, making analogies to the process of constructing a house. The steps are also related to Kagan's (1991) stages of organizational development. From laying the foundation of the partnership through adding the sill (the vision), constructing the frame (the goals and objectives), adding the sheathing (the formal structure), installing siding (the implementation), to maintaining through assessment, the parallels are explored and analyzed. Because the process relates to individuals as well as an institution, the authors also discuss ways in which the processes diverge.

The process is presented as a model that might be useful to others engaged in creating a professional development school or improving teacher education. A visual of the model is included.     

Modelling method of recursive entity

With the development of the Information and Communication Technologies, great masses of information are published in the Web. In order to reuse, to share and to organise them in distance formation and e‐learning frameworks, several research projects have been achieved and various standards and modelling languages developed. In our previous article, the limits of theses languages were examined and a new method named the recursive entity modelling method (REMM) was established to overcome these limits. But, when it was revised, some limitations were discovered. So, in this paper, an improved version of the REMM will be proposed, and the diagram of classes for a scenario modelled by this version will be established. In addition, both the learning scenario package and the generic XML schema permitting to implement these scenarios will be conceived.     

Developing and acting upon one's conception of the nature of science: A follow‐up study

This study aimed to delineate the factors mediating the translation of preservice teachers' conceptions of the nature of science into instructional planning and classroom practice. Additionally, the study assessed the influence of temporally separating teaching preservice teachers about the nature of science and teaching them how to address it instructionally. This latter intervention was based on the results of a previous investigation. Prior to student teaching, the 13 participants responded to an open‐ended questionnaire designed to assess conceptions of the nature of science. Throughout student teaching, daily lesson plans, classroom videotapes, portfolios, and supervisors' weekly clinical observation notes were collected and searched for explicit instances of nature of science planning and/or instruction. Following student teaching, participants were interviewed to validate their responses to the open‐ended questionnaire, identify factors that mediate the translation of their conceptions of the nature of science into classroom teaching, and explicate their pedagogical preferences for teaching the nature of science. Participants possessed adequate understanding of several aspects of the nature of science and, contrary to the results of the earlier investigation, most did not conflate the nature of science with science processes. Furthermore, several participants explicitly addressed some aspects of the nature of science during classroom instruction. Participants, however, failed to include the nature of science among their instructional objectives and did not make a concerted effort to assess student understandings. © 2000 John Wiley & Sons, Inc.

Transport and deposition of airborne pollutants in exhibition areas located in historical buildings–study in Wawel Castle Museum in Cracow,Poland

Historical buildings and castles that have been turned nowadays into museums, as an exhibition area for precious cultural heritage (CH) items, need more attention since they are CH objects by themselves. Moreover, the preservation techniques require often, significant interventions; however such changes are not always possible or are very limited. The aim of the present study was to investigate the influence of outdoor air pollution on the composition of particulate matter and gases inside the museum of Wawel Castle in Cracow, Poland. During this study a combination of micro and trace analysis techniques were applied, including energy dispersive X-ray fluorescence (EDXRF) and electron probe microanalysis (EPMA). An intensive transport of air pollutants coupled with accumulation of the particles inside the museum was noticed (considerably higher in winter than summer). A high content of carbon and organic matter agglomerated with inorganic particles was determined. Those particles are of special concern because of their adhesive properties and reactivity. It was also noted that the conditions inside the museum favour the reaction of the particles with gaseous pollutants. It was especially the case for nitrate particles.

The Warsaw study in socio-cognitive psychology of education

The article presents one of ways, in which educational psychology in Poland has been practiced. It may be called a socio-cognitive approach. The basic concepts of this approach concern the process of interaction between educators and their children. They are: the situation, the bi-subject model, the field of shared meanings, the act of communication, levels of control, expectations, complementary roles, the typisation of persons and situations, behavioural patterns. Then, this theoretical model is ilustrated by the recent researches made in the Warsaw University. The general question of them was: how to educate to promote the development of agency in students. At the last part of the paper some directions of current researches are also presented.     

Representations of nature of science in high school chemistry textbooks over the past four decades

This study assessed the representations of nature of science (NOS) in high school chemistry textbooks and the extent to which these representations have changed during the past four decades. Analyses focused on the empirical, tentative, inferential, creative, theory‐driven, and social NOS, in addition to the myth of “The Scientific Method,” the nature of scientific theories and laws, and the social and cultural embeddedness of science. A total of 14 textbooks, including five “series” spanning one to four decades, were analyzed. The textbooks commanded significant market shares in the United States and were widely used in some of the most populace states. Relevant textbook sections were scored on each of the target NOS aspects on a scale ranging from −3 to +3, which reflected the accuracy, completeness, and manner (explicit versus implicit) in which these aspects were addressed. The textbooks fared poorly in their representations of NOS. Additionally, with a few exceptions, textbook scores either did not change or decreased over the past four decades. These trends are incommensurate with the discourse in national and international science education reform documents, which has witnessed an increasing emphasis on the centrality of NOS to scientific literacy and pre‐college science education during the same time period. Assessment and evaluation strategies, and policies need to be targeted if substantial and desired changes in the ways NOS is addressed in science textbooks are to be effected. © 2008 Wiley Periodicals, Inc.
