Eight middle school mathematics teachers’ perceptions and uses of curriculum materials and the Common Core State Standards for Mathematics (CCSSM) were investigated. Adapting a noticing framework and models of dialogic instruction and direct instruction, teachers’ noticing practices with curriculum materials and the CCSSM when planning, enacting, and reflecting on lessons were examined. Teachers who were committed to implementing the CCSSM and who were using one of two substantively different curriculum programs were purposefully selected. Data sources included multiple forms of interviews and classroom observations. The teaching evidenced three distinct noticing patterns. These patterns indicated that teachers’ curriculum materials were associated with how teachers perceived and enacted the CCSSM. Teaching with a curriculum program that was designed as a thinking device prioritized the Standards for Mathematical Practice of CCSSM evidenced noticing that was consistent with dialogic instruction. Teaching with a curriculum program that was designed as a delivery mechanism prioritized the Content Standards of CCSSM and evidenced noticing consistent with direct instruction. Findings indicated that the designated curriculum and contributed to differing interpretations of CCSSM and served as a lens for noticing. However, a dialogic curriculum program was not sufficient to support dialogic approaches in practice. One pattern showed teachers planning dialogic lessons, but the lesson enactments were not consistent with teachers’ plans, with evidence that the teachers were not aware that their practices differed from dialogic approaches. Implications for research and practice are discussed.  相似文献

This study examined the personal characteristics and resources in 65 licensed family child care providers' lives that influence developmentally enhancing caregiving and professional commitment to child care. Several self-report instruments were utilized to assess providers' personal characteristics and resources. The Family Day Care Rating Scale (FDCRS: Harms & Clifford, 1989) was used to assess quality of care during morning observations at providers' homes, while the Organizational Commitment Questionnaire (OCQ: Mowday, Steers, & Porter, 1979) was adapted to assess professional commitment to family child care. Factors in providers' lives that uniquely contributed to higher levels of quality care were higher levels of formal education and training, college coursework in ECE, higher levels of psychological well-being, and higher family incomes. Common factors in providers' lives that predicted higher levels of professional commitment to child care were helpful and supportive resources for child care and higher levels of psychological well-being.  相似文献

OBJECTIVE: The prevalence of sexual abuse during childhood or adolescence varies depending on the definitions and age categories used. This study examines the first national, population-based data available on child sexual abuse that occurs before age 15 in three countries: El Salvador, Guatemala, and Honduras. This study uses comparable indicators and measures of sexual abuse for the three countries to document the prevalence of abuse, types of perpetrators, and the association of child sexual abuse with recent intimate partner violence. METHODS: Child sexual abuse was defined as sexual abuse that first occurs before age 15. Nationally representative data from El Salvador, Guatemala, and Honduras were used. In El Salvador, separate questions on forced intercourse and non-penetrative sexual abuse were asked. Bivariate and multivariate analyses were performed using STATA Version 8SE. RESULTS: The prevalence of child sexual abuse varied from 7.8% in Honduras to 6.4% in El Salvador and 4.7% in Guatemala. In all three countries, the overwhelming majority of women who reported child sexual abuse first experienced the abuse before age 11. Perpetrators tended to be a family member, a neighbor, or an acquaintance. Bivariate and multivariate analyses indicated that women who experienced child sexual abuse in Guatemala and Honduras were about two times more likely to be in violent relationships as women who did not experience abuse. This relationship was not significant in multivariate analyses for El Salvador where the prevalence of intimate partner violence was the lowest. CONCLUSIONS: Child sexual abuse in Central America is clearly a problem with the prevalence between 5% and 8%. Child sexual abuse can have long-term negative health impacts including exposure to intimate partner violence in adulthood. Programs to prevent abuse and treat victims of child sexual abuse are needed in Central America.  相似文献

Computers, once available exclusively to wealthy industries, are now rapidly becoming as familiar in preschool and kindergarten classrooms as block and crayons. Articles making claims such as Learning by Computers at Age 4 and Computers Preparing Preschoolers for Kindergarten now permeate the news media. Increasing numbers of child care centers, attempting to maximize public interest in computers, now readily advertise Computer Tutor in their literature. Computer Tutor is often even listed above other important qualifications such as certified teachers and professional affiliations of centers.Theresa Rubens has had extensive experience working with children in both family day homes and child care centers. Jennifer Poole is the Nursery Director at the First United Methodist Church in Carrollton, TX. James L. Hoot is Assistant Professor of Early Childhood Education at North Texas State University in Denton, Texas.  相似文献

Both participation in dialog and exposure to others from different cultures have been theorized to increase the ability of an individual to be creative. This study focused on the multicultural student-to-student dialog that took place in one graduate level course. The purpose of this study was to explore how participation in this dialog might influence student creativity, specifically how the students generated creative ideas for their final course papers. No connection was found between participation in the multicultural student-to-student dialog and the generation of creative ideas for their final papers. However, insight was gained into the creative process used by students in generating their final paper ideas.  相似文献

Background

The casual, abbreviated writing style sometimes known as ‘textese’ (e.g., sorry im late ?) has become widespread with the rise of digital communication. We explored Australian university students' views on, and use of, textese across three modalities (text message, Facebook post, email) and three recipient types (friends, peers, lecturers).

Methods

In Study 1, 51 undergraduates composed messages across the three modalities to the three recipient types. They also rated the appropriateness of messages written with high, medium and no textese, across modality and recipient types. In Study 2, 37 additional students provided examples of their own sent messages across modalities and recipients.

Results

Overall, participants rated textese use as more appropriate, and used significantly more textese, in messages to friends, than to peers, than to lecturers.

Conclusions

Undergraduates are sensitive to when and where it is appropriate to use textese and vary their use (and opinions) of written language as a function of the recipient.

OBJECTIVE: To determine the demographic and psychosocial correlates of physical and sexual abuse among children with autism. METHODS: Data collected from 1997 to 2000 through the national evaluation of the Comprehensive Community Mental Health Services for Children and their Families Program on 156 children with autism were used. Data included a baseline assessment of child and family psychosocial experiences and presenting problems associated with referral into system-of-care service, demographic information, and a clinical record review to obtain psychiatric diagnosis. Binary and multinomial logistic regression was used to determine the association of different characteristics of children who were abused compared with those who were not abused. RESULTS: Caregivers reported that 18.5% of children with autism had been physically abused and 16.6% had been sexually abused. Physically abused children more likely had engaged in sexual acting out or abusive behavior, had made a suicide attempt, or had conduct-related or academic problems. Sexually abused children more likely had engaged in sexual acting out or abusive behavior, suicidal or other self-injurious behavior, had run away from home, or had a psychiatric hospitalization. In adjusted multivariate models, the relationship between sexual abuse and sexual acting out, running away from home and suicidal attempts persisted. CONCLUSION: Based on the prevalence of abuse and its association with various behaviors, clinicians should be as attuned to the psychosocial histories of children with autism as they are for other children, and consider the potential of abuse when these behaviors are observed.  相似文献

Deep learning of science involves integration of existing knowledge and normative science concepts. Past research demonstrates that combining physical and virtual labs sequentially or side by side can take advantage of the unique affordances each provides for helping students learn science concepts. However, providing simultaneously connected physical and virtual experiences has the potential to promote connections among ideas. This paper explores the effect of augmenting a virtual lab with physical controls on high school chemistry students’ understanding of gas laws. We compared students using the augmented virtual lab to students using a similar sensor-based physical lab with teacher-led discussions. Results demonstrate that students in the augmented virtual lab condition made significant gains from pretest and posttest and outperformed traditional students on some but not all concepts. Results provide insight into incorporating mixed-reality technologies into authentic classroom settings.  相似文献

In summary, this author recommends that should an instructor decide to deliver an online instructional design course it is important to understand three things: 1. Recognize that as with any course, the content, delivery methods, and media used can be individualistic. You can shape the course to meet the needs of your students and the expectations of your institution. 2. Realize that the ideas presented in this article should be used as a guide. Differences in course requirements, accreditation standards, and other program factors may affect what can or needs to be accomplished. 3. Know that one of the first things your students will ask about (and call you on) is your own ability to design instruction. This author’s students asked about how this course was developed and how the instructional design process was implemented for this course.  相似文献
