This paper presents findings from a 4-year project that developed and implemented a blended inquiry science and English Language Development (ELD) program in a large urban California school district. The sample included over 2,000 students in Kindergarten through 5th grade. Participating students’ English and science achievement was compared to a similar group of students who were using the district’s established English language development curriculum. Student performance on statemandated English and science assessments were analyzed using Mann–Whitney U tests for overall performance and by number of years of treatment. Modest but statistically significant improvement was found for students who participated in the blended program. Results from this study suggest that restricting instructional minutes for science to provide additional time for ELD and English language arts may be unnecessary. Rather, allowing consistent time for science instruction that incorporates ELD instruction along with inquiry science experiences may provide the authentic and purposeful context students need to develop new language without restricting access to science content. 相似文献

We describe a model professional development intervention currently being implemented to support 3rd- through 5th-grade teachers’
science instruction in 9 urban elementary schools with high numbers of English language learners. The intervention consists
of curriculum materials for students and teachers, as well as teacher workshops throughout the school year. The curriculum
materials and workshops are designed to complement and reinforce each other in improving teachers’ knowledge, beliefs, and
practices in science instruction and English language development for ELL students. In addition to these primary goals, secondary
goals of the intervention included supporting mathematical understanding, improving scientific reasoning, capitalizing on
students’ home language and culture, and preparing students for high-stakes science testing and accountability through hands-on,
inquiry-based learning experiences. 相似文献

Our 5-year professional development intervention is designed to promote elementary teachers’ knowledge, beliefs, and practices
in teaching science, along with English language and mathematics for English Language Learning (ELL) students in urban schools.
In this study, we used an end-of-year questionnaire as a primary data source to seek teachers’ perspectives on our intervention
during the first year of implementation. Teachers believed that the intervention, including curriculum materials and teacher
workshops, effectively promoted students’ science learning, along with English language development and mathematics learning.
Teachers highlighted strengths and areas needing improvement in the intervention. Teachers’ perspectives have been incorporated
into our on-going intervention efforts and offer insights into features of effective professional development initiatives
in improving science achievement for all students.

Advocates of constructivist science recommend that school science begins with children’s own constructions of reality. This
notion of the way in which students’ knowledge of science grows is closely paralleled by recent research on teachers’ knowledge.
This paper draws on case study evidence of teachers’ work to show how two experienced teachers’ attempts to develop alternative
ways of teaching science involved reframing their previous patterns of understanding and practice. Two alternative interpretations
of the case study evidence are offered. One interpretation, which focuses on identifying gaps in the teachers’ knowledge of
science teaching, leads to theconstructivist paradox. The second interpretation explores theconstructivist parallel, an approach which treats the process of teachers’ knowledge growth with the same respect as constructivists treat students’
learning of science. This approach, the authors argue, is not only more epistemologically consistent but also opens up the
possibilities of helping teachers lead students towards a constructivist school science.

Every aspect of teaching, including the instructional method, the course content, and the types of assessments, is influenced
by teachers’ attitudes and beliefs. Teacher education programs play an important role in the development of beliefs regarding
teaching and learning. The purpose of the study was to document pre-service teachers’ views on science, scientists, and science
teaching as well as the relations between these views and the offered courses over several years spent in an elementary science
teacher training program. The sample consisted of 145 pre-service elementary science teachers who were being trained to teach
general science to students in the 6th through 8th grades. The research design was a cross-sectional study. Three different
instruments were used to collect the data, namely, the “Draw a Scientist Test”, “Draw a Science Teacher Test”, and “Students’
Views about Science” tests. The elementary science teacher training program influenced pre-service science teachers’ views
about science, scientists and science teaching to different degrees. The most pronounced impact of the program was on views
about science teaching. Participants’ impressions of science teaching changed from teacher-centered views to student-centered
ones. In contrast, participants’ views about scientists and science did not change much. This result could be interpreted
as indicating that science teacher training programs do not change views about science and scientists but do change beliefs
regarding teaching science. 相似文献

This survey study explored high school science teachers’ challenges and needs specific to their growing English language learning
(ELL) student population. Thirty-three science teachers from 6 English as a Second language (ESL)-center high schools in central
Virginia participated in the survey. Issues surveyed were (a) strategies used by science teachers to accommodate ELL students’
special needs, (b) challenges they experienced, and (c) support and training necessary for effective ELL instruction. Results
suggest that language barriers as well as ELL students’ lack of science foundational knowledge challenged teachers most. Teachers
perceived that appropriate instructional materials and pedagogical training was most needed. The findings have implications
for science teacher preservice and inservice education in regard to working with language minority students.

This study explored the nature of science (NOS) assessments K-4 classroom teachers developed for measuring students’ understandings
of NOS elements. We used the Views of Nature of Science Questionnaire-Form VNOS-D2 (Views of Nature of Science Elementary
School Version 2) and interviews to verify that teachers’ conceptions of NOS were sufficient to enable them to teach and assess
NOS. We collected copies of teachers’ action research designs, lesson plans, and assessment tools, conducted classroom observations
and made field notes of their science instruction and assessments. We videotaped conversations at monthly workshops to note
discussion surrounding teaching and assessing NOS in K-4 classrooms. We found that experienced teachers designed a variety
of strategies for assessing NOS conceptions that differed by grade level. 相似文献

Teacher motivation has been found to be a critical predictor of teachers’ work commitment, identity and performance, yet has
received insufficient attention in educational policymaking. In this article the reasons for people becoming teachers of English
as a foreign language in China, reflect both social and psychological factors. This motivational aspect of becoming and being
a teacher, in particular a teacher of English, provides an avenue for capturing teachers’ meaning and understanding of teaching
in their context through the narratives of their experience of why and how they teach English. To develop a policy aimed at
sustaining the intrinsic motivation of teachers, it is crucial to analyze the issues that affect a teacher’s commitment and
identity. 相似文献

In the context of the emphasis on inquiry teaching in science education, this study looks into how pre-service elementary
teachers understand and practise science inquiry teaching during field experience. By examining inquiry lesson preparation,
practice, and reflections of pre-service elementary teachers, we attempt to understand the difficulties they encounter and
what could result from those difficulties in their practice. A total of 16 seniors (fourth-year students) in an elementary
teacher education program participated in this study. In our findings, we highlight three difficulties ‘on the lesson’ that are related to teaching practices that were missing in the classrooms: (1) developing children’s own ideas and curiosity,
(2) guiding children in designing valid experiments for their hypotheses, (3) scaffolding children’s data interpretation and
discussion and another three difficulties ‘under the lesson’ that are related to problems with the pre-service teachers’ conceptualization of the task: (4) tension between guided and
open inquiry, (5) incomplete understanding of hypothesis, and (6) lack of confidence in science content knowledge. Based on
these findings, we discuss how these difficulties are complexly related in the pre-service teachers’ understandings and action.
Several suggestions for science teacher education for inquiry teaching, especially hypothesis-based inquiry teaching, are
then explored. 相似文献

Current standards emphasize student engagement with inquiry practices. However, implementing inquiry instruction is a formidable
challenge for teachers as they often lack models for using and adapting inquiry-based instructional materials. Teacher education
programs can provide scaffolded contexts for developing teachers’ ability to critique, adapt, and design inquiry-based materials.
We describe a qualitative study of 17 preservice teachers enrolled in two consecutive science methods courses. The study characterizes
the development of preservice teachers’ ability to critique and revise instructional materials. Our findings suggest that
teachers improved in their ability to critique lesson plans and to suggest revisions that would make them more inquiry oriented.
In particular, the teachers’ critiques and revisions increased in sophistication after engaging in instructional design activities
during the second methods course. 相似文献

This paper reports on a study of elementary preservice teachers’ inquiry-based practices, their efficacy beliefs, and the
role beliefs had on two preservice teachers’ practices in urban classrooms. Results show inquiry-based practices can be cultivated
through field-based experiences and preservice teachers’ efficacy beliefs, as it relates to practice in urban settings, are
malleable. Specifically, personal efficacy beliefs about teaching science improved or were sustained for one cohort of preservice
teachers. However, beliefs about students’ ability to learn science, that is outcome beliefs, were less stable. The results
of two case studies show that science content knowledge was a factor in preservice teachers’ inquiry-based practices. However,
why preservice teachers’ beliefs about student learning declined is less clear. More research is needed, along with follow-up
data on teacher induction, to learn how preservice teachers’ beliefs impact urban students’ science education. 相似文献

Over recent decades, educators have recognized the crucial importance of teaching environment and contextual factors in teaching
and learning outcomes. Public and private schools are among those teaching contexts that have been in competition for teaching
quality and effectiveness for many years. This study investigated the effectiveness of some English teachers in these two
school contexts in a foreign language setting, Iran. Seventy-six public and private high schools in a small city in Iran were
selected, and their English teachers’ performance was evaluated by an external observer and self-evaluation using a high-inference
observation instrument and a questionnaire. The result of the data analysis showed that English teachers who worked in private
schools were more effective teachers than their colleagues in public schools. The results also revealed that teacher effectiveness
and their years of teaching experience and age were weakly but significantly related. Furthermore, it was found that teachers’
type of university degree and the location of schools (disadvantaged vs. privileged areas of the city) were not related to
teachers’ effectiveness. 相似文献

We explore the potential of dilemma analysis as an assessment tool to reveal student teachers’ thinking and concerns about
their practice. For this purpose we analyze the dilemma analyses completed by 22 student teachers enrolled in our science
teacher preparation program over a period of four semesters. Student teachers’ dilemmas fall into two main groups: dilemmas
about student performance and dilemmas associated with instructional decisions. These dilemmas reveal a variety of concerns
that student teachers have about their work. In particular, concerns about lack of student motivation and its consequences
on performance and instruction play a central role in student teachers’ thinking. The recognition of common patterns of thought
in our student teacher thinking has made us reflect on and re-evaluate important components of the curriculum in our science
teacher preparation program. 相似文献

This study examines the process of change among grade 4 teachers (students aged 9–10 years) who participated in a yearlong
Teacher Quality Grant innovation program. The concerns-based adoption model (CBAM), which informed the design and implementation
of the program, was used to examine the process of change. Two questions guided the investigation: (1) How did teachers’ concerns
about and levels of use of the innovation evolve during the course of the project? (2) What changes in teachers’ perceptions
and practices arose as a result of the innovation? Results showed that several of the teachers’ concerns evolved from self/task
toward impact. With continued support, several participants achieved routine levels of use, which they sustained beyond the
project. 相似文献

This article describes an innovative approach to developing preservice elementary science teachers’ classroom confidence and
skills. Based on lesson study approaches, preservice candidates designed and taught integrated science–mathematics lessons
during the semester before their student teaching. Working in teams, candidates designed and taught a common lesson in 3 different
classrooms, critiquing and refining their lesson between each teaching activity. Data collected from observations of classroom
teaching events, team reports, and individual reflections were analyzed qualitatively. Results indicate that, over the 3 teaching
events, there were dramatic improvements in lesson design and delivery, the management of the learning environment, the quality
of students’ engagements with meaningful content, and the quality of assessments and generation of student data.
According to the website of the Lesson Study Research Group, there were more than 2,300 teachers in over 335 schools involved
in lesson study in the U.S. as of May 2004 (www.tc.edu/lessonstudy/). Additional lesson study information, projects, and resources
are available through a number of other websites, including www.lessonresearch.net (at Mills College) and www.uwlax.edu/sotl.lsp

This study examines how teachers’ use of affective strategies (voice intonation, dramatization, personal involvement comments)
during the reading and discussion of books influence young children’s affective reactions (dramatization, personal engagement,
language play comments). Twenty kindergarten teachers read four books, two fiction and two information ones (narrative/expository
text).
We found significant differences in both teachers’ affective presentation and young children’s affective reactions between
fiction and information books, between the two fiction books but not between the narrative and expository text. A strong bi-directional
relationship was found between teachers’ affective presentation of stories and young children’s affective reactions. In particular,
teachers’ personal involvement comments prompted children’s personal engagement reactions, teachers’ reenactment was followed
by children’s imitations of such reenactments and teachers’ voice intonation elicited children’s personal engagement comments.
On the other hand, children’s use of paralinguistic cues and personal engagement comments reinforced teachers’ use of voice
intonation and personal involvement comments. Finally, text features, such as rhyming, were followed by children’s language
play. 相似文献

The study examines the professional development of junior-high-school teachers participating in the Israeli “Katom” (Computer
for Every Class, Student and Teacher) Program, begun in 2004. A three-circle support and training model was developed for
teachers’ professional development. The first circle applies to all teachers in the program; the second, to all teachers at
individual schools; the third to teachers of specific disciplines. The study reveals and describes the attitudes of science
teachers to the integration of laptop computers and to the accompanying professional development model. Semi-structured interviews
were conducted with eight science teachers from the four schools participating in the program. The interviews were analyzed
according to the internal relational framework taken from the information that arose from the interviews. Two factors influenced
science teachers’ professional development: (1) Introduction of laptops to the teachers and students. (2) The support and
training system. Interview analysis shows that the disciplinary training is most relevant to teachers and they are very interested
in belonging to the professional science teachers’ community. They also prefer face-to-face meetings in their school. Among
the difficulties they noted were the new learning environment, including control of student computers, computer integration
in laboratory work and technical problems. Laptop computers contributed significantly to teachers’ professional and personal
development and to a shift from teacher-centered to student-centered teaching. One-to-One laptops also changed the schools’
digital culture. The findings are important for designing concepts and models for professional development when introducing
technological innovation into the educational system. 相似文献
