This article presents an analysis of intercultural education from the viewpoint of the dynamics of agenda building as a political process. In this analysis, particular attention is given to the theoretical and ideological assumptions on which the concept of intercultural education is based. The author contends that the employment of this concept serves the purpose of issue containment within the arena of conflict where educational policy alternatives are determined.
Background: Technological pedagogical content knowledge (TPACK) is critical for effective teaching with technology. However, generally science teacher education programs do not help pre-service teachers develop TPACK.
Purpose: The purpose of this study was to assess pre-service science teachers' TPACK over a semester-long Science Methods.
Sample: Twenty-seven pre-service science teachers took the course toward the end of their four-year teacher education program.
Design and method: The study employed the case study methodology. Lesson plans and microteaching observations were used as data collection tools. Technological Pedagogical Content Knowledge-based lesson plan assessment instrument (TPACK-LpAI) and Technological Pedagogical Content Knowledge Observation Protocol (TPACK-OP) were used to analyze data obtained from observations and lesson plans.
Results: The results showed that the TPACK-focused Science Methods course had an impact on pre-service teachers’ TPACK to varying degrees. Most importantly, the course helped teachers gain knowledge of effective usage of educational technology tools.
Conclusion: Teacher education programs should provide opportunities to pre-service teachers to develop their TPACK so that they can effectively integrate technology into their teaching. 相似文献
Recently, the model of adoption of technology in households (MATH) was developed and tested in the context of household personal computer (PC) adoption. In this study, we apply MATH to predict personal computer (PC) use. We conducted a nationwide survey including 370 households that owned at least one PC. Results indicate that attitudinal beliefs are extremely important in determining use of a PC in the household. In contrast to previous work examining adopters, normative and control beliefs were not significant in predicting use. Furthermore, several determinants of adoption that were important at different stages of the household life cycle were found nonsignificant in predicting use for the same stages of the household life cycle. Overall, the results demonstrate that the belief structure for household PC use is different from that of household PC adoption. Further, the results provide additional evidence regarding the importance of including household life cycle in studies of household technology adoption and use. 相似文献
This study examined the initial implementation process of Advancement Via Individual Determination (AVID) in a northern California community college. Focus groups of students, faculty, and administrators were conducted in the spring of 2008, as well as observations of several planning meetings in the spring and summer of 2008. The community college students enrolled in the AVID class reported that the support they received through AVID has helped them focus, become more organized, and become more motivated to continue their studies. This was so even though not all of AVID's 11 essentials were implemented on campus. In addition, challenges such as faculty buy-in and resistance to changing institutionalized practices were encountered by staff members responsible for implementing AVID. In this initial implementation, faculty and administration sought to change the culture of the college to better serve the underrepresented students in their quest to transfer to four-year institutions. This study provides a framework for other community colleges and higher education institutions to leverage the academic potential of underprepared and historically underrepresented students. 相似文献
Recommender systems have dramatically changed the way we consume content. Internet applications rely on these systems to help users navigate among the ever-increasing number of choices available. However, most current systems ignore the fact that user preferences can change according to context, resulting in recommendations that do not fit user interests. This research addresses these issues by proposing the \(({ CF})^2\) architecture, which uses local learning techniques to embed contextual awareness into collaborative filtering models. The proposed architecture is demonstrated on two large-scale case studies involving over 130 million and over 7 million unique samples, respectively. Results show that contextual models trained with a small fraction of the data provided similar accuracy to collaborative filtering models trained with the complete dataset. Moreover, the impact of taking into account context in real-world datasets has been demonstrated by higher accuracy of context-based models in comparison to random selection models. 相似文献
This study examines the broadcast content of the first black air personalities in New Orleans leading up to and during to the Civil Rights Movement of the 1950s and 1960s. The black broadcasters worked in concert with civil rights leaders, offering them opportunities to be interviewed on air, but did not get extensively involved such as using their radio shows to recruit foot soldier.
O.C.W. Taylor integrated radio in 1946 at WNOE. His talk show portrayed industrious blacks in a positive light. In 1948, Vernon "Dr. Daddy-O" Winslow became the city's first black DJ working at WJMR. Winslow mostly played rhythm and blues and hip New Orleans music aimed at blacks, but he did reassure worried listeners that the young people participating in sit-ins were not physically harmed.
Larry McKinley gave rise to radio news coverage of the Movement. He arrived at WMRY as an 18-year-old in 1953. Later, in the early 1960s at WYLD, McKinley and broadcaster George "Tex" Stevens, as well as Taylor at WNOE, interviewed activists concerning their push to get Coca Cola to hire black truck drivers. The leaders discussed the successful end of a two-year boycott of more than 30 downtown stores. They also talked of their experiences during the Freedom Riders campaign, sit-ins, and other demonstrations. While the broadcasters did not on-air recruit African Americans to join Movement activities, they announced the times and locations of meetings which were often held at the black churches. 相似文献
