We investigated the inclusion of a curricular module on global climate change in an Elementary Science Methods course. Using
complementary research methods, we analyzed findings from 63 teacher candidates’ drawings, questionnaires, and journal entries
collected throughout their participation in the module. We highlighted three focal cases to illustrate the diversity of participants’
experiences. Findings suggest potential positive impacts on teacher candidates’ content understanding related to global climate
change, confidence to teach, and awareness of resources to support their future science instruction. Recommendations for science
teacher education underscore the importance of providing opportunities for teacher candidates to increase their relevant content
understanding, helping teacher candidates become familiar with appropriate curricular resources, and engaging in ongoing conversation
and evaluation of developing views and understandings related to global climate change. 相似文献

This article encourages the increased attention to issues of reception in rhetoric of science, according with the sentiment but not the argument of Paul, Charney, and Kendall's “Moving beyond the Moment.” In particular, it offers two works as exemplary of the disciplinary maturity that has occasioned this focus on reception, Ceccarelli's monograph, Shaping Science with Rhetoric, and Harris's collection, Rhetoric and Incommensurability. 相似文献

Colleges of Business (COBs) have experienced high growth rates in the past decade and many colleges are imposing minimum grade point average (GPA) requirements for students to enter or remain in the college. A primary reason for this requirement may be the belief that students with high GPAs are more inclined to demonstrate higher‐order cognitive skills (HOCS) than students with low GPAs. It is not clear whether the link is valid. This study hypothesizes that students with high GPAs who are taught in the same way as students with lower GPAs will have higher perceptions of improved HOCS. We conducted an experiment in which students, with varying GPAs, at three large universities primarily used multimedia instructional materials. We obtained the students' perceptions of their improved HOCS from their responses to a survey. A regression analysis of the data reveals that the relationship between GPAs and students' perceived improvement in HOCS is significant (p < .001). We conclude the study by recommending that (a) it is critical to use research methodologies to evaluate perceived and actual learning improvements, (b) COB policies to implement GPA restrictions on admission are worthwhile, and (c) case studies need to be used much more frequently in undergraduate COB classes. 相似文献

The Next-Generation Science Standards (NGSS) challenge primary teachers and students to work and think like scientists and engineers as they strive to understand complex concepts. Teachers and teacher educators can leverage what is already known about inquiry teaching as they plan instruction to help students meet the new standards. This cross-case analysis of a multiple case study examined teacher practices in the context of a semester-long professional development course for elementary teachers. We reviewed lessons and teacher reflections, examining how kindergarten and first grade teachers incorporated NGSS scientific and engineering practices during inquiry-based instruction. We found that most of the teachers worked with their students on asking questions; planning and carrying out investigations; analyzing and interpreting data, using mathematics and computational thinking; and obtaining, evaluating and communicating information. Teachers faced challenges in supporting students in developing their own questions that could be investigated and using data collection strategies that aligned with students’ development of number sense concepts. Also, some teachers overemphasized the scientific method and lacked clarity in how they elicited and responded to student predictions. Discussion focuses on teacher supports that will be needed as states transition to NGSS. 相似文献

Sexuality education programs can be broadly categorized as either risk-avoidance or risk-reduction approaches. Health educators in Utah public schools must teach a state mandated risk-avoidance curriculum which prohibits the advocacy or encouragement of contraception. Multiple national surveys indicate that parents prefer a risk-reduction approach to sexuality education that promotes abstinence and the use of condoms or contraception for prevention of unwanted pregnancy and sexually transmitted infection. To date, no survey of Utah parents has been conducted.This study utilized an Internet survey to gather data from 344 Utah parents to analyze their preferences regarding school-based sexuality education, sexuality topics, and support for objectives from the National Sexuality Education Standards. The vast majority of Utah parents surveyed support a risk-reduction approach to sexuality education, a wide variety of sexuality topics, and the majority of National Sexuality Education Standards. Statistically significant differences were identified by parents’ education, income, attendance at religious services, and political affiliation. Results support that Utah laws and education policies should be reexamined to provide for instruction that aligns with professional recommendations, best-practice recommendations based on peer-reviewed research, parental attitudes, and the needs of Utah teens. 相似文献

In this paper I discuss my experience in using the inverted classroom structure to teach a proof-based, upper level Advanced Calculus course. The structure of the inverted classroom model allows students to begin learning the new mathematics prior to the class meeting. By front-loading learning of new concepts, students can use valuable class time for exploring and solving complex problems, with the instructor available for guidance and assistance. This paper compares student performance in the inverted classroom with student performance in the direct instruction classroom. I also share student perceptions of the inverted classroom experience. 相似文献

This agenda-setting study explores ways that individuals processinformation issues by examining two potential public agendasources: the news media and the president of the USA. The researchersused a two-site study to examine the magnitude of influencefrom media exposure and perceived credibility of source. Itwas found that the higher the level of exposure to media anda presidential state-of-the-union message, the more likely thatissues were considered important. However, when both were examinedsimultaneously, media exposure was the more powerful predictor.Source credibility, both of the media and the president, wasalso found to influence how people perceived the importanceof issues. 相似文献
