The Impact of a Geospatial Technology-Supported Energy Curriculum on Middle School Students’ Science Achievement 总被引：3，自引：2，他引：1
Geospatial technologies are increasingly being integrated in science classrooms to foster learning. This study examined whether a Web-enhanced science inquiry curriculum supported by geospatial technologies promoted urban middle school students’ understanding of energy concepts. The participants included one science teacher and 108 eighth-grade students classified in three ability level tracks. Data were gathered through pre/posttest content knowledge assessments, daily classroom observations, and daily reflective meetings with the teacher. Findings indicated a significant increase in the energy content knowledge for all the students. Effect sizes were large for all three ability level tracks, with the middle and low track classes having larger effect sizes than the upper track class. Learners in all three tracks were highly engaged with the curriculum. Curriculum effectiveness and practical issues involved with using geospatial technologies to support science learning are discussed. 相似文献

This content analysis explored how previously validated Web-based inquiries (WBIs) for science instruction are designed and to what extent they match the proposed teacher-support guidelines of the American Association for the Advancement of Science. Examined WBIs implemented few recommended teacher-support mechanisms. This article explores the reasons why so few mechanisms were supported and proposes ways to enhance the curricular usefulness of WBIs by incorporating more recommended mechanisms. 相似文献

Although the demand for multicultural children's literature dates back to the mid-nine-teenth century, recent years have seen
a rejuvenation and expansion of the field. Publishers large and small have responded to this demand in a variety of ways.
This article reviews the current status of multicultural children's literature and trends in publishing. It also offers suggestions
for publishers who want to be more responsive to these demands and the growing market they represent.
She teaches undergraduate and graduate courses in children's literature. Her current research interests are in the literacy
materials created for African-American children prior to 1950 and literature reflective of the various ethnic communities
in the United States. 相似文献

The peer rating system used here advances the quantitative literacy goals outlined in the social sciences. We instituted a mid-semester intervention to teach rating skills and used an index to track longitudinal changes of skill mastery over the course of the semester. Seventy-four students in five advanced research classes followed the procedure of the existing peer rating system by completing reading assignments, writing reflections online, engaging in class discussions, rating their peers’ reflections and receiving feedback on their group effort. Peer ratings were then compared with each other and also with the instructor ratings to derive individualised indices of reliability and validity. These technical indicators enabled two rounds of assessment before and after a class-wide intervention. An omnibus test across the five classes showed a significant improvement in rating quality due to the intervention. Our courses not only met a quantitative learning outcome but also promised vocational competence. 相似文献
