This paper describes the use of a three-circle Venn diagram as a vehicle for introducing pre-service elementary teachers to pedagogical content knowledge (PCK). Each circle of the diagram represents pedagogy, content and context individually. The overlap of any two circles represents the interaction between the circles. For example, the overlap of pedagogy and context relates to the ways that each of these general topics influences the other. The overlap of all three circles represents a complete lesson that is an integration of the three major components of PCK. The Venn diagram is an easily remembered graphic illustration of PCK that can be useful in planning lessons. The use of this graphic organizer in a science capstone course required of all pre-service elementary teachers is described. 相似文献

Gardnerella vaginalis (GV) infection has been reported as being acquired via sexual contact in adults and as an indicator of sexual contact in female children (DeJong, 1985). The purpose of this study was to determine if GV infection was more commonly found in 191 female children who gave a history of sexual contact and/or were infected with Neisseria gonorrhoeae (GC) or Chlamydia trachomatis (CT) (Group 1), compared with 144 female children evaluated for possible sexual abuse and found to have no such history or infection with GC or CT (Group 2), or 31 female children (friends of the authors) without such a history or GC or CT infection (Group 3). Vaginal GV was found in 5.3% of Group 1, 4.9% of Group 2 and 6.4% of Group 3 (p > .05). Also, vaginal GV infection was not related to the type of sexual contact or race, but did increase with age in white female children. Because vaginal GV infection is not more commonly found in children with a history of sexual contact than those without such a history, the finding of GV in a vaginal culture in an individual case would not be a reliable marker of sexual contact. Routine culturing for GV is not recommended as part of a sexual abuse workup. 相似文献

In order to determine if Ureaplasma urealyticum (Uu) or large colony mycoplasma (LCM) colonization was related to a history of sexual abuse, the type of sexual contact, an enlarged vaginal introitus transverse diameter (greater than 4 mm), age or race, 452 female children, ages 1-12 years, were evaluated by the Child Sexual Abuse Team at Wake Medical Center in Raleigh, NC. Thirty-six girls were deleted because of inadequate cultures. When controlled for race and age, Uu throat (T), vaginal (V), and rectal (R) colonization and LCM vaginal and rectal colonization were not related to any of the other variables listed above. The enlarged vaginal introital diameter was related to a history of sexual abuse (p less than .001). Uu and LCM vaginal colonization rates were increased in black girls as compared to white girls (p less than .05). Uu V, Uu R, LCM V, and LCM R colonization increased with age. In our study population, Uu and LCM colonization was not a useful marker of sexual contact. 相似文献

In this article, we describe an innovative capstone course for preservice K-8 teachers integrating action research and a unifying
theme in science (AAAS in Science for all Americans. Oxford University Press, New York, 1989; NRC in National science education standards. National Academy Press, Washington, DC, 1996). The goals of the capstone course are to increase student knowledge of the unifying theme, improve written communication
skills, and introduce students to educational research. We provide evidence that each of these goals is met. Student growth
in theme knowledge is demonstrated through concept maps, questionnaires, and previously reported assessments. Improved writing
ability is demonstrated using the spelling and grammar checking feature of Microsoft Word. The analysis of action research
reports demonstrates that students are able to connect their action research project results to previous research. 相似文献
