This research centers on the psychometric examination of the structure of an instrument, known as the 5E Lesson Plan (5E ILPv2) rubric for inquiry-based teaching. The instrument is intended to measure an individual’s skill in developing written 5E lesson plans for inquiry teaching. In stage one of the instrument’s development, an exploratory factor analysis on a fifteen-item 5E ILP instrument revealed only three factor loadings instead of the expected five factors, which led to its subsequent revision. Modifications in the original instrument led to a revised 5E ILPv2 instrument comprised of twenty-one items. This instrument, like its precursor, has a scoring scale that ranges from zero to four points per item. Content validity of the 5E ILPv2 was determined through the expertise of a panel of science educators. Over the course of five semesters, three elementary science methods instructors in three different universities collected post lesson plan data from 224 pre-service teachers enrolled in their courses. Each instructor scored their students’ post 5E inquiry lesson plans using the 5E ILPv2 instrument recording a score for each item on the instrument. A factor analysis with maximum likelihood extraction and promax oblique rotation provided evidence of construct validity for five factors and explained 85.5 % of the variability in the total instrument. All items loaded with their theoretical factors exhibiting high ordinal alpha reliability estimates of .94, .99, .96, .97, and .95 for the engage, explore, explain, elaborate, and evaluate subscales respectively. The total instrument reliability estimate was 0.98 indicating strong evidence of total scale reliability. 相似文献

AbstractThe current study aimed to examine differences in ecological values between Indonesian and Korean preservice science teachers. Fifteen items from revised-New Ecological Paradigm based on value orientations were used as the research instrument. Two hundred seventy-three preservice science teachers participated in the study. Rasch analyses of dimensionality, item fit, and differential item functioning were used to explore the validity of the instrument. The independent-sample T-test and Pearson’s correlation test were utilized to compare data from the two countries. Preservice science teachers from the two different countries showed significant differences in only one of the three value orientations, which is egoistic value. Relationships among cultural, educational, and economic factors, as well as environmental values in these countries are discussed to fully explore the findings. 相似文献

The study investigated the effects of three types of evaluation on preservice teachers’ performance, knowledge and attitudes
related to writing lesson plans that incorporate technology. Subjects were randomly assigned to one of the three treatment
conditions: teacher-evaluation, self-evaluation or peer-evaluation. All groups completed three class periods of instruction
on writing lesson plans, then each subject submitted his/her draft lesson plan. The drafts were evaluated by assigned evaluators
(teacher, self or peer), who provided scores and written feedback on a 15-item rubric. Students then revised their lesson
plans into final form. All three treatment groups improved their lesson plans significantly from draft version to final version,
with the teacher-evaluation group showing significantly greater improvement and writing significantly better final lesson
plans than each of the other two groups. Teacher-evaluation and self-evaluation groups had significantly higher scores on
a knowledge-based posttest than the peer-evaluation group. Several suggestions are discussed for making further improvements
in the self-evaluation and peer-evaluation processes. 相似文献

The purpose of this study was to develop a questionnaire that could measure preservice mathematics teachers' mathematics educational
values. Development and validation of the questionnaire involved a sequential inquiry in which design principles were established
from the existing literature and a pool of items was constructed then submitted to experts for consideration of the construct
validity. Alterations to the items based on their suggestions were made to produce a trial version of the questionnaire. A
pilot study involving preservice mathematics teachers explored the validity and usefulness of the questionnaire. The pilot
results were used to revise the questionnaire that was administered to a sample of preservice mathematics teachers attending
Cumhuriyet University, Sivas, Turkey. Further explorations of the construct and structural validity, item contributions, and
reliability were achieved by using a factor analysis and two different item analysis methods. Results revealed that the questionnaire
included four factors, satisfactory item contributions, and acceptable internal consistency. One result obtained in this study
suggested that some mathematics education values based on Western culture (e.g., accessibility–special) have not been accepted
by Turkish preservice mathematics teachers. 相似文献

This study explored a modified version of Japanese Lesson Study to determine whether and how it influenced preservice elementary teachers in their abilities to deliver science lessons that included nature of science (NOS) to their own students. We used a case study approach that focused on one subset of a cohort of preservice elementary teachers within their field placement settings. Data sources included lesson plans, lesson feedback forms, videotapes of delivered lessons, and videotapes of lesson study feedback sessions. Early in the semester peers provided feedback on content, and later in the semester peers provided feedback on classroom management as well as content during the lesson study feedback sessions. We found that preservice elementary teachers were able to provide feedback to their peers regarding how to include NOS in their science lessons, yet did not naturally included NOS connections within their own lessons. 相似文献

The challenge of preparing students for the information age has prompted administrators to increase technology in the public schools. Yet despite the increased availability of technology in schools, few teachers are integrating technology for instructional purposes. Preservice teachers must be equipped with adequate content knowledge of technology to create an advantageous learning experience in science classrooms. To understand preservice teachers’ conceptions of technology integration, this research study explored 15 elementary science methods students’ definitions of technology and their attitudes toward incorporating technology into their teaching. The phenomenological study took place in a science methods course that was based on a constructivist approach to teaching and learning science through science activities and class discussions, with an emphasis on a teacher beliefs framework. Data were collected throughout the semester, including an open-ended pre/post-technology integration survey, lesson plans, and reflections on activities conducted throughout the course. Through a qualitative analysis, we identified improvements in students’ technology definitions, increased technology incorporation into science lesson plans, and favorable attitudes toward technology integration in science teaching after instruction. This research project demonstrates that positive changes in beliefs and behaviors relating to technology integration in science instruction among preservice teachers are possible through explicit instruction. 相似文献

This study investigated how preservice teachers develop collective efficacy when preparing lesson plans for a science methods course, and how this collective efficacy changed over time. The data were collected from four preservice science teachers working in a group to fulfil the requirements of the course. Findings revealed that four factors, including collaborative work, sharing the same goal, attitudes towards group work and group cohesion, played an important role in the development of collective efficacy among preservice teachers. The study also showed that collective efficacy improved continuously over the semester. 相似文献

ABSTRACT Looking closely at lesson plans as mediating tools, this study examines preservice teacher learning. By using activity theory in our analysis of lesson plans and other data collected in a student-teaching course, we uncovered tensions within/across the contexts of university teacher education program and secondary school field placements. This study serves to further understandings of how new teachers learn to appropriate the genres of teaching and to explore contradictions between a university preparation program and secondary school contexts. Findings provide an account of the student–teachers’ lesson planning and an explanation of how disruptions in those plans provided insight into points of tension. By viewing these tensions as contradictions within/across activity systems, we identify them as opportunities to better understand teacher learning and ways we might support new teachers in navigating tensions in their classrooms and schools. 相似文献

Abstract Teachers' evaluation of pupil learning should be consistent with identified learning outcomes at the intended level of performance. To the extent that curriculum and assessment are aligned, the validity of inferences about pupil knowledge is strengthened. The purpose of this investigation was to evaluate the assessment practices of preservice teachers who have successfully completed coursework in educational measurement. Three hundred and nine lesson plans from 65 preservice (student) teachers were reviewed. The authors found that, during student teaching, preservice teachers do not follow many of the assessment practices recommended in their coursework. Perhaps implementations of recommended classroom assessment practices seem to depend on more than possessing the requisite knowledge. 相似文献

This study examined 158 lesson plans at one institution across two teacher education programs, inclusive early childhood and elementary education, to determine the impact of Internet usage as inspiration on preservice teachers’ lesson plans. Fisher’s exact test determined statistically significant differences between the Internet use of preservice teachers in the two programs. The data revealed that the preservice teachers in the elementary education program used more Internet resources when planning lessons compared to the preservice teachers in the inclusive early childhood program. Follow-up interviews suggest that the preservice teachers in the inclusive early childhood program had more practicum field experiences, thus increasing their use of physical resources and reducing their use of Internet resources. 相似文献

This study presents the systematic development, validation, and use of a new instrument for measuring student interest in science and technology. The Student Interest in Technology and Science (SITS) survey is composed of 5 sub-sections assessing the following dimensions: interest in learning science, using technology to learn science, science careers, technology careers, and attitudes toward biotechnology. Our development process included review of existing instrumentation, pilot testing, and expert panel review. The resulting instrument was administered before and after implementation of a biotechnology intervention which used a computer-based game to engage learners in the use of biotechnology to address a societal issue. We employed item response theory (IRT) to explore instrument validity and precision. Results of the psychometric analyses suggest that the SITS survey has a well-defined structure and meets IRT assumptions. Difficulty and discrimination parameters as well as reliability analyses indicate that SITS items provide useful measures of student interest. Finally, we use the SITS to explore the extent to which the intervention used in this study supports changes in student interest and association between students’ interest and related content knowledge. Implications for the future use of this instrument are discussed. 相似文献

This study examined preservice teachers’ (PSTs) capacity for lesson planning in a university-based teacher preparation program in the USA Participants (n?=?126) wrote lesson plans in three approaches: synthesis, creation, and modification. Findings indicate that PSTs who modified preexisting lesson plans produced better lesson plans than their peers and reported higher efficacy in their use of the lesson plan in their field experiences. This study supports the notion that the efficacy of first-year teaching lies more appropriately in the area of enacting curriculum than in the area of designing curriculum. With respect to career-long learning, PSTs’ abilities to do curriculum work are likely to improve, as they grow more familiar with students and existing excellent curricula over years. Although the study presents a snapshot of U.S. preservice teachers’ capacity for curriculum design, the findings may serve to inform the literature on the developmental aspect of curriculum design for teacher education systems across the world. 相似文献

This study explored whether early childhood preservice teachers' concerns about teaching nature of science (NOS) and their intellectual levels influenced whether and how they taught NOS at the preschool and primary (K‐3) levels. We used videotaped classroom observations and lesson plans to determine the science instructional practices at the preschool and primary levels, and to track whether and how preservice teachers emphasized NOS. We used the Stages of Concern Questionnaire (SOCQ) pre‐ and postinternship to determine concerns about NOS instruction, and the Learning Context Questionnaire (LCQ) to determine intellectual levels. We found that neither concerns about teaching NOS nor intellectual level were related to whether and how the preservice teachers emphasized NOS; however, we found that all preservice early childhood teachers began their internships with NOS concern profiles of “worried.” Two preservice teachers' NOS concerns profiles changed as a result of their internships; one to “cooperator” and one to “cooperator/improver.” These two preservice teachers had cooperating teachers who were aware of NOS and implemented it in their own science instruction. The main factors that hindered or facilitated teaching NOS for these preservice teachers were the influence of the cooperating teacher and the use of the science curriculum. The preservice teacher with the cooperating teacher who understood and emphasized NOS herself and showed her how to modify the curriculum to include NOS, was able to explicitly teach NOS to her students. Those in classrooms whose cooperating teachers did not provide support for NOS instruction were unable to emphasize NOS. © 2009 Wiley Periodicals, Inc. J Res Sci Teach 47:213–233, 2010 相似文献

This study reports the results of a survey of special education teachers regarding: (a) how special education teachers organize and develop their lesson plans, (b) which lesson plan components special education teachers include in their lesson planning activities and how each component is planned, and (c) what lesson plan components special education teachers recommend that beginning teachers include in written lesson plans. As indicated by the results, the majority of the special education teachers who participated in this study did not write out lesson plans for each lesson they taught. They indicated that, even though most of the planning prior to instruction was unwritten, it was often "consciously" planned, or planning was unnecessary because the component was performed by habit or instinct. A substan- tial majority indicated that they did not use any expert's lesson planning format, such as Hunter's (1984) or a format suggested in preservice teacher training. None of the 14 components regularly included in preservice lesson plans and instructional design models were written out by a majority of the teachers; only 3 of the 14components were written out by over one third of the respondents. Conversely, this study demonstrated that, although these teachers did not write out detailed lesson plans, they strongly recommended that beginning teachers do so. All 14 components were recommended by at least one third of the respondents, with 8 recommended by a majority. Limitations, questions for future investigation, and implications for teacher preparation are discussed. 相似文献

This study explored the relationships among preservice teachers' conceptions of teaching using mobile devices and the quality of technology integration in lesson plans. A total of 47 preservice teachers in Taiwan who had experienced designing their own lesson plans and teaching materials (ie, eBooks and applications) for teaching using mobile devices (ie, smart phones and tablet PCs) participated in this study. The results showed that four qualitatively different conceptions of teaching using mobile devices were identified, namely “technology support,” “knowledge transmission,” “learning facilitation,” and “supporting students to learn.” This study also found that the teachers who had more constructivist perceptions of teaching using mobile devices, such as facilitating students' understanding in a convenient way or supporting student learning in a more active way, appeared to attain better quality technology integration in their lesson plans than those teachers with traditional conceptions. 相似文献

The use of content validity as the primary assurance of the measurement accuracy for science assessment examinations is questioned. An alternative accuracy measure, item validity, is proposed. Item validity is based on research using qualitative comparisons between (a) student answers to objective items on the examination, (b) clinical interviews with examinees designed to ascertain their knowledge and understanding of the objective examination items, and (c) student answers to essay examination items prepared as an equivalent to the objective examination items. Calculations of item validity are used to show that selected objective items from the science assessment examination overestimated the actual student understanding of science content. Overestimation occurs when a student correctly answers an examination item, but for a reason other than that needed for an understanding of the content in question. There was little evidence that students incorrectly answered the items studied for the wrong reason, resulting in underestimation of the students' knowledge. The equivalent essay items were found to limit the amount of mismeasurement of the students' knowledge. Specific examples are cited and general suggestions are made on how to improve the measurement accuracy of objective examinations. 相似文献

This study investigated how 46 pre-service teachers (PSTs) planned for differentiation of instruction in mathematics. Content analysis was utilized to explore the differentiation strategies included and student characteristics considered in PST plans and how PSTs used differentiation strategies and student characteristics to differentiate lesson content, process, product, and environment. In addition, a rubric was designed and utilized to analyze the level of detail PSTs provided in their plans. Results indicated that overall, PSTs were developing in their planning for differentiation of instruction, using general terms to describe the modifications they would make to meet student needs. Moreover, results revealed that PSTs included strategies to differentiate lesson content and environment most often in their plans and frequently considered student readiness levels when planning for differentiation. Findings also revealed that PSTs need support in learning how to plan for differentiation based on student cultural backgrounds. Implications for mathematics teacher preparation are discussed.
