This single-subject study assessed the effects of in-classroom coaching on early childhood teachers’ use of emergent literacy teaching strategies. Teaching strategies were grouped into clusters related to oral language and comprehension of text, phonological awareness and alphabetic principle, and print concepts and written language, with coaching being applied to each cluster separately. The coaching process included two primary components: a brief initial meeting to introduce teaching strategies in the cluster, and semi-weekly observation with follow-up discussion using data collected during the observation. A third, booster component was added when the teacher did not achieve a pre-established criterion. Participants were five early childhood teachers, three in child care programs and two in public school pre-kindergarten programs. The intervention phase lasted approximately 6 weeks for each teacher. Results indicated that this approach to coaching was effective for increasing the number of teaching strategies that teachers used in each cluster. Individual differences among teachers are discussed, and implications for future research and practice are explored.  相似文献

There has not been enough critical analysis of children’s literature by and about Chinese Americans, especially when compared to other minority groups in the United States. In particular, Chinese American historical books lack extensive analysis. It is important to reflect cultural accuracy in literature and to help children develop clear concepts of self and others by providing precise cultural and physical characteristics of people. While cultural authenticity allows children the opportunity to see a reflection of real experiences within a book instead of seeing stereotypes or misrepresentations, obtaining correct information about a certain time period can help children to see images of immigration accurately represented in literature. Using the Confucian delineation of interpersonal relationships as the major criterion of cultural authenticity, this article examines three currently available children’s picturebooks set in the historical period between 1848 and 1885. In addition to exploring how Chinese Americans’ interpersonal relationships are portrayed in these children’s historical books, this article argues for more proactive inclusion of the diversity in selection of picturebooks.  相似文献

ABSTRACT

The purpose of the current study was to investigate students’ overall learning process during the implementation of educational escape-the-room games (EERGs) in classrooms. This study adopted a two-stage case-study methodology, namely single-case and multi-case designs. In the first stage, a well-designed EERG for a Chinese language class was developed on a web-based game platform. A total of 15 second-grade students from a public elementary school in Taiwan used tablet computers to engage in problem-solving tasks in the EERG. In the second stage, five schoolteachers from other elementary schools who had adopted similar EERGs in their classrooms in the previous academic year participated in the study to share their instructional experiences. The results indicated that students actively collaborated with their team members to address problem-solving tasks during the EERG activity. Positive collaborative learning experiences and learning attitudes towards the EERG were identified in the students’ self-reflection worksheets.  相似文献

Abstract

High school underrepresented minority students in the US are at an increased risk of dropping out of the STEM pipeline. Based on expectancy-value theory, we examined if Latino students’ perception of support from parents, siblings/cousins, teachers, and friends in 10th grade predicted their science ability self-concepts and values, which in turn predicted their classroom engagement. Survey data were collected from 104 Latino high school students and their science teachers. The findings suggest that adolescents’ perceptions of overall support and home-based support predicted adolescents’ science ability self-concepts at 10th grade while controlling for their 9th grade self-concepts. Although adolescents reported high support from teachers, teacher or school-based support alone was not a strong correlate of their motivational beliefs. Perceived support was indirectly related to classroom engagement through adolescents’ ability self-concepts. Feeling supported across home and school may be necessary to sustain adolescents’ science motivational beliefs and, in turn, their science classroom engagement.  相似文献

In the last several decades it has become an important basis to retrieve images from image databases (IDBs) by the semantic information held in the image objects and the spatial patterns formed by these objects. In this paper, we propose a new method for similarity retrieval of symbolic images by both the attributes and the spatial relationships of the contained objects. The proposed method CPM (common pattern method) retains the common spatial patterns of two images in new data structures CP_DAG (common pattern directed acyclic graph) and performs the similarity calculation efficiently in practice. The conducted experiments use both a synthetic dataset and an existing image database. The experimental results show that CPM outperforms LCS_Clique, SIMR, SIMDTC, and 2D Be-string for average efficiency and effectiveness. CPM also has steady efficiency while the number of image objects and the object symbol duplication rates increase.  相似文献

Students' learning style preferences have been widely adapted into teaching and learning environments. The purpose of this study was to investigate the relationship between self-reported and assessed learning style preferences (visual, auditory, reading/writing, kinesthetic: VARK) on performance in different types of multiple-choice examinations (T1: text only format and T2: visual format) given in an introductory biomechanics class. Students who enrolled in three biomechanics classes at a state university were recruited to participate in the study. Ninety students (47 males and 43 females) completed a learning style survey and two types of examinations. Results showed that approximately half of the students were assessed and self-reported as kinesthetic for their preferred learning style. There was no significant difference in test performance between students who preferred visual and reading/writing learning styles (self-reported and assessed). These students demonstrated similar learning and comprehension of biomechanical concepts regardless of whether the test material was presented in their preferred sensory mode or not. Interestingly, female students' perceptions of their learning style preference may have a positive effect on the test results when the test is presented in their preferred format.  相似文献

Current approaches to workplace learning emphasize designing communities of practice that are intended to support both formal and informal knowledge acquisition. This article presents the design and research of a knowledge‐based community of practice for Subaru, based on principles outlined by Scardamalia (2002) and Zhang, Scardamalia, Lamon, Messina, and Reeve (2007). The purpose of this study was to investigate the extent to which participants' interactions in the online community showed evidence of individual and collective knowledge building. We found evidence of knowledge building within online discussions in these areas: interactions around improvement of ideas, connection to workplace knowledge and practices, and building on or adopting the ideas of others. We also found significant gains in scores on an assessment of workplace customer service after participation in the online community of practice.  相似文献

The rise of mobile learning in schools during the past decade has led to promises about the power of mobile learning to extend and enhance student cognitive engagement. The purpose of this study was to examine trends to determine the cognitive level students are involved in within mobile learning activities. This systematic review involved an aggregated and configurative synthesis of PK-12 mobile learning studies from 2010 to 16 and used Bloom’s Taxonomy as a theoretical framework for categorizing the cognitive level of student activities. Major new findings include that students are involved in activities at all six levels of Bloom’s Taxonomy. This study shows that over 60% of researchers are developing activities that require high levels of cognitive processing, a large increase from past studies. Nonetheless, 40% are integrating mobile devices in ways that keep students working with minimal cognitive processing. In both elementary and secondary studies, there was a 40/60% split in the use of lower versus high level thinking opportunities. New findings show that mobile devices were integrated into science, mathematics, social studies, literacy, art and special education. Studies in science settings were the majority of the studies (40%), followed by literacy (24%).  相似文献

ABSTRACT

This cross-sectional study explored students’ conceptions of science learning via drawing analysis. A total of 906 Taiwanese students in 4th, 6th, 8th, 10th, and 12th grade were asked to use drawing to illustrate how they conceptualise science learning. Students’ drawings were analysed using a coding checklist to determine the presence or absence of specified attributes. Data analysis showed that the majority of students pictured science learning as school-based, involving certain types of experiment or teacher lecturing. In addition, notable cross-sectional differences were found in the ‘Activity’ and ‘Emotions and attitudes’ categories in students’ drawings. Three major findings were made: (1) lower grade level students conceptualised science learning with a didactic approach, while higher graders might possess a quantitative view of science learning (i.e. how much is learned, not how well it is learned), (2) students’ positive and negative emotions and attitudes toward science learning reversed around middle school, and (3) female students expressed significantly more positive emotions and attitudes than their male counterparts. In conclusion, higher graders’ unfruitful conceptions of science learning warrant educators’ attention. Moreover, further investigation of girls’ more positive emotions and attitudes found in this study is needed.  相似文献
