The students are usually eager to develop their mathematical learning. However, the Skolverket can see that this eagerness passes in the early years of school. A study shows that a varied mathematical education creates enthusiasm to learn, which can decrease the negative view of mathematics. The purpose of this study is to see how five pedagogues use laboratory mathematics, their approaches to laboratory mathematics as well as to find out their role in the laboratory education. The result of the study is based on interviews with the pedagogues, who are all teachers for students in year F-3. All of the pedagogues work in a laboratory way, but to different extents. The study shows that the pedagogues aim to make the mathematics as concrete and everyday as possible. The pedagogues use the laboratory way of working and materials in different ways and have slightly different views of what counts as laboratory material. Further, the study shows that there are more possibilities than obstacles with the laboratory way of working. The five pedagogues all agree that this way of working is beneficial for the pupils, especially for the students who are poor achievers. The possible obstacles raised by the pedagogues were lack of time and to some extend shortage of material. Two important factors within this way of working are communication and briefings.

This study was designed to determine (a) the nature and extent of planning and programmatic changes that occurred in Indiana schools that have incorporated the Ball State University (BSU) Professional Development School (PDS) model; (b) how the implementation of these changes had impacted the school principal's roles and responsibilities; (c) whether the principal serving as site coordinator effected the school or principal's work; and (d) whether geographic classification effected process or outcomes. Interviews were conducted with the principal, site coordinators and teachers during March 1999. Findings:1.The principals, teachers, and university faculty were continuously involved in planning.2.Although the duration of planning varied, all schools used planning committees, research and multiple planning processes.3.The most notable changes were instructional modifications and collaborative teaching.4.Half of the principals (two urban and one suburban) became more facilitative and more inclined to use shared decision making.5.Half of the schools had a change in the principalship during planning; one school had four different principals during this period.6.Site coordinators had a positive influence on shared decision making.7.More change occurred in the urban schools. Conclusions:1. Ongoing communication and shared decision making helped diminish possible negative consequences of principal turnover during planning.2.Differences in planning duration and frequency did not appear to affect outcomes.3.Transition to a PDS had more effects on the urban schools, suggesting that climates and cultures in suburban schools were initially more congruous with the PDS philosophy.4.The philosophy of the PDS requires a collaborative leadership style on the part of the principal. Those unwilling to assume this role are likely to withdraw from the principalship. Having the principal not serve as the site coordinator promotes collaboration and shared authority.5.Suburban educators were inclined to view PDS issues politically, while the urban educators were inclined to view them economically.Recommendations:1. The leadership style of a principal should be a primary consideration in selecting possible PDS sites.2.Longitudinal studies of PDSs should be conducted in the areas of student academic growth, curriculum, and faculty satisfaction. / Department of Educational Leadership

The quality of analytical data produced by geochemical laboratories has become progressively more important as complex decisions concerning the impact of development on the environment Public concern regarding the impact of resource, industrial, and agricultural development is placing greater pressure on the government to protect the environment (Zhou, 2013). The quality of such data is squarely dependent on adherence to quality control programs, which provide guidelines from which high quality, trustworthy data can be generated. A unique quality control program was developed and implemented at the NSERC-IRC Aqueous and Environmental Geochemistry Laboratory. This program: 1) accommodate samples from unique environments; 2) documents and maintains the high level of confidence in the data produced; 3) provides standard quality control protocols; and 4) ensures the continued training of staff. The evaluation of data produced during 2013 revealed the strengths and weaknesses of the laboratory methods through comparison with data quality objectives. The data produced by the laboratory during 2013 was evaluated and quality confirmed. It was determined that the results produced met the high standards required by the data quality objectives, with a few minor exceptions. The quality objectives were based on the end use of the data and consideration regarding the complex nature of the water samples collected from diverse geologic media. There was increased variability of results near the method detection limit of selenium, cadmium, and arsenic, although they still meet to standards required for water quality investigations. Investigations into variabilities will include re-evaluation of detection limits, identification of the source of discrepancy between the methods, and possible matrix interference. Protocols will continue to be monitored and changes to methods made when objectives are not achieved or there are changes in laboratory staff, equipment, or the specific requirements of the studies the laboratory supports.
