This article reports the findings of a 3-year study of a hybrid professional development program designed to prepare science and mathematics teachers to implement GIS in their classrooms. The study was conducted as part of the CoastLines Innovative Technology Experiences for Students and Teachers project funded by the National Science Foundation. Three cohorts of teachers participated in the program, with each participant receiving 40 h of synchronous online instruction and 80 h of in-person instruction and support over an 8-month period. Data from surveys of participants both before and after the program were analyzed using correlation, ordinary least squares, and ordered logit regression analyses. The analyses revealed increases in the self-reported frequency of GIS use and enhanced feelings of preparation, competence, community, and comfort with respect to using GIS for instruction. A composite index of all impact variables was positively influenced as well. The statistical analyses found a strong relationship between self-reported feelings of preparation and use of GIS. Some support was found for the idea that feelings of competence, community, and comfort were related to the teachers’ sense of preparation. The findings suggest that a robust hybrid model of teacher professional development can prepare teachers to use GIS in their classrooms. More research is needed to understand how hybrid models influence the sociopsychological and other dimensions that support teachers’ feelings of preparation to implement GIS.
Magical realism as a literary mode is often subversive and transgressive, questioning the values and assumptions of the dominant society that it depicts. Young adult literature, by contrast, is typically thought to serve a socializing function, helping to integrate young readers into adult society. What then is the cultural work of magical realism when it appears within young adult novels? An examination of three young adult novels—by Francesca Lia Block, David Almond, and Isabel Allende—reveals that they employ magical realism to accomplish socialization through subversion. 相似文献
This study examined a model of college student choice for male and female ninth graders using LISREL. A sample of 703 male students and 718 female students and their parents responded to two sets of questionnaires regarding high school experiences and expectations about college. Endogenous variables examined included parents' expectation regarding higher education for their children, parents' savings for college, students' discussion of college with their parents, and students' aspiration for postsecondary education. The model explained 30.8% of the variance in students' aspiration for males and 36.8% for females. Final empirical models for the two groups suggested that there may be subtle differences in family influence on male and female students' college-going plans. 相似文献
It is commonly believed that the standard of student performance in coursework tends to be higher than that achieved in formal examinations. This view was tested by analysing undergraduate performances in six subjects at four UK universities. Two measures of relative coursework performance were employed. The first is the difference between the mean coursework and examination marks for each module. The second considers the proportion of students in each module who achieve a higher mark in the coursework than in the examination. The measures showed that in English and History coursework performances are slightly higher, equivalent to one-third of one honours class (or division) while, in Biology, Business Studies, Computer Studies and Law, coursework performances are higher by as much as two-thirds of one honours class (or division). The differences observed in the latter subjects are very significant and have serious implications for parity of treatment in degree programmes where students may choose modules with contrasting modes of assessment. 相似文献
OBJECTIVE: The aims were: (1) to examine the profile of African street children and to assess the link between street children in Africa and political violence; (2) to undertake a systematic examination of causal factors of street children in postgenocide Rwanda; and (3) to situate this analysis in the context of the socio-cultural and political impact of the genocide on Rwandan communities. METHOD: Observational mapping examined the profile and activities of Rwandan street children. Structured interviews were carried out with 290 children in four regional towns to obtain information on socio-demographic, familial, educational background, causal factors surrounding street life involvement, psychological well-being, and relationship to the street. Focus group discussions and key informant interviews examined the relationship between street children and the broader Rwandan society. RESULTS: Street children in Rwanda were predominantly adolescent boys, almost half of whom were homeless (42%), with a high proportion of orphaned children or children who had lost at least one parent. Two variables predicted homelessness: child's guardian and reason for being in street. Qualitative accounts of children conveyed the impact of death of family members, repatriation, imprisonment of parents, and poverty on their lives. CONCLUSIONS: The analysis highlighted the need for community based support for children in alternative guardianship care and for policies to support the reintegration of male youths in postconflict welfare strategies as prevention strategies for street migration. 相似文献
