The classic film “Powers of Ten” is often employed to catalyze the building of more accurate conceptions of scale, yet its
effectiveness is largely unknown. This study examines the impact of the film on students’ concepts of size and scale. Twenty-two
middle school students and six science teachers participated. Students completed pre- and post-intervention interviews and
a Scale Card Sorting (SCS) task; all students observed the film “Powers of Ten.” Experienced teachers’ views on the efficacy
of the film were assessed through a short written survey. Results showed that viewing the film had a positive influence on
students’ understandings of powers of ten and scale. Students reported that they had more difficulty with sizes outside of
the human scale and found small scales more difficult to conceptualize than large scales. Students’ concepts of relative size
as well as their ability to accurately match metric sizes in scientific notation to metric scale increased from pre- to post-viewing
of the film. Experienced teachers reported that the film was a highly effective tool. Teachers reported that the design of
the film that allowed students to move slowly from the human scale to the large and small scales and then quickly back again
was effective in laying the foundation for understanding the different scales.

Strategies for Designing Engaging Online Kinesiology Courses Based on the Community of Inquiry Model
Technology integration has become an ever-present phenomenon in institutions of higher education. This has led to an increase in online learning experiences that make higher education accessible to those who previously experienced barriers, such as having full-time jobs. One issue that affects online education is the challenge of engaging the learner in meaningful learning experiences that they subsequently use once they are in their careers. This article uses the Community of Inquiry (CoI) theoretical model to explain how instructors can increase student engagement in online kinesiology courses. By focusing on the CoI constructs of teaching presence, cognitive presence, and social presence, instructors can design engaging online classes that can help to positively influence each student’s experience with online education. 相似文献

This article examines nation state policies that have prioritized toleration of diversity over recognition through comparative case studies of three junior secondary schools in Botswana. Through data collected in observations, focus groups, interviews and participatory action research, we demonstrate how the schools, which varied in the ethnic composition of their students, teachers and surrounding communities, responded differently to the reality of their multicultural student bodies. Two followed national policies closely, while the third crafted school-level policies adapted to its student population, yet tightly constricted by national policies and curriculum. In all three schools, students of ethnic minority backgrounds experienced varying degrees of shame, discrimination and a sense of exclusion from the nation and found little recourse to discuss and address these experiences within the structures of their schools. We argue that schools could better develop students’ capacity for equal citizenship were they supported by national education policies and curriculum to recognize the cultural, historical and linguistic diversity of Botswana’s ethnic minorities explicitly in schools. 相似文献

Studies over the last 30 years have considered various factors related to student success in introductory biology courses. While much of the available literature suggests that the best predictors of success in a college course are prior college grade point average (GPA) and class attendance, faculty often require a valuable predictor of success in those courses wherein the majority of students are in the first semester and have no previous record of college GPA or attendance. In this study, we evaluated the efficacy of the ACT Mathematics subject exam and Lawson’s Classroom Test of Scientific Reasoning in predicting success in a major’s introductory biology course. A logistic regression was utilized to determine the effectiveness of a combination of scientific reasoning (SR) scores and ACT math (ACT-M) scores to predict student success. In summary, we found that the model—with both SR and ACT-M as significant predictors—could be an effective predictor of student success and thus could potentially be useful in practical decision making for the course, such as directing students to support services at an early point in the semester. 相似文献

AbstractWe might call this decade the era of early childhood. In the US, federal and state governments invest in the creation of public pre-kindergarten (preK) programs and create standards that articulate goals for practice and benchmarks that can be used to evaluate success. How have these trends provided a context for the evolution of preK curriculum? In this paper, we analyze the enactment of preK policy in New Jersey, a highly regulated preK program and Wisconsin, a local control state. We argue that standards-based practice is evolving into accountability in public preK programs, where outcomes set parameters for planning and teachers and children are increasingly regulated. As preK is more closely affiliated with the K-12 sector (elementary and secondary), preK programs are subject to the logic of alignment, benchmarks and assessments. Even when early learning standards support child-centered approaches to curriculum they are overruled by accountability discourse. 相似文献

Recent research highlights the potential benefits of practice without feedback on learner’s strategy knowledge. However, most prior work has been conducted in one-on-one settings with short retention intervals. We compared the effects of mathematics practice with and without correct-answer feedback on immediate and 1-week delayed performance in a classroom setting. In a randomized experiment, 243 second- and third-grade children received strategy instruction and then practiced solving relevant problems in small groups within their classroom. During practice, children received immediate feedback (after each problem), summative feedback (after all the problems in the set), or no feedback. During the practice task, immediate feedback led to the best performance. However, practice without feedback led to higher levels of mastery on the 1-week knowledge retention test. Thus, instructional practices that seem less effective at first can, for some children, ultimately result in more desirable learning. 相似文献

We argue that one important role of the contemporary president is to be a conductor of public feelings. To demonstrate, we analyze U.S. President Barack Obama’s national eulogy speech delivered on January 12, 2011 in Tucson, Arizona. We show how Obama acts as a musical or energy conductor, redirecting a soundscape of boisterous enthusiasm to be in concert with discordant feelings of national pain and anger and moving them toward social love that is non-partisan and at times civic-centered. This essay has implications for public policy, racial registers of feeling, and writing the bodies of rhetorical scholars into criticism. 相似文献

This cross‐sectional study examined the relationship between interest, social–emotional skills, and early math skills in preschool children. Math‐specific interest and global interest in learning were measured using teacher report and a play‐based observation task. Math skills were assessed with a test of math achievement, and social–emotional skills were assessed using a teacher‐report measure. Children with higher global interest in learning, math‐specific interest, and observed goal‐directed play demonstrated higher math skills. Furthermore, social‐emotional skills were associated with global interest in learning and math skills, but not with math‐specific interest. Overall, findings support the relevance of interest and social‐emotional skills for school readiness in young children. 相似文献

The middle level classroom presents unique challenges to educators who strive to provide opportunities that acknowledge learner diversity in terms of social, cognitive, physical, and emotional development. This is confounded even further within inclusive middle-school classrooms where the responsibility to differentiate instruction is even more critical. One way to meet the needs of all students is through cooperative grouping. Through cooperative grouping, middle-level educators can differentiate instruction and promote active learning by leveraging the naturally social nature of young adolescents. In this article, the authors present research on cooperative grouping as well as several considerations for effectively designing and implementing cooperative grouping for middle-level learners in an inclusive setting. Suggestions and examples with regard to group size, membership, group structure and roles, and classroom management and clear expectations are provided. Additionally, the four-clue group strategy is presented as a specific instructional method to support effective group learning experiences in the inclusive middle-level classroom. 相似文献
