This study explores prospective teachers’ skills of attending, interpreting and responding to content-specific characteristics of mathematics instruction in classroom videos. Prospective teachers analyzed the mathematics instruction of two teachers through four video clips and proposed alternative instructional ways to support the teaching and learning of mathematics. The results indicated that as prospective teachers examined the teachers’ instructional practices, they increased their level of attending and interpretation to content-specific aspects of instruction rather than focusing on generic dimensions of the instruction. When they watched and compared different characteristics of teachers’ mathematics instruction, they provided more detailed and mathematical instructional suggestions.  相似文献

Our study addresses the relationship between teacher talk and children’s conceptual learning in early science instruction. We examined the role of teacher talk in N = 32 kindergarten classes. The teachers were video-recorded at the beginning of a four-week instruction phase while assisting a group of children who were dealing with a learning unit on floating and sinking. The coding of teacher talk included expressions that were pertinent to the content (content-specific vocabulary) and talk that performed an underlying scaffolding function (scaffolding utterances). Teachers’ scaffolding utterances were assigned to four sub-types. The children’s conceptual understanding was measured in individual sessions in a pre-post design. The results of two different analytic approaches indicated that the teachers’ content-specific language acted as a positive predictor of the children’s learning outcomes whereas both positive and negative effects were found with respect to the sub-types of scaffolding utterances.  相似文献

With growing interest in the role of teachers as the key mediators between educational policies and outcomes, the importance of developing good measures of classroom processes has become increasingly apparent. Yet, collecting reliable and valid information about a construct as complex as instruction poses important conceptual and technical challenges. This article summarizes the results of two studies that investigated the properties of measures of instruction based on a teacher‐generated instrument (the Scoop Notebook) that combines features of portfolios and self‐report. Classroom artifacts and teacher reflections were collected from samples of middle school science classrooms and rated along 10 dimensions of science instruction derived from the National Science Education Standards; ratings based on direct classroom observations were used as comparison. The results suggest that instruments that combine artifacts and self‐reports hold promise for measuring science instruction with reliability similar to, and sizeable correlations with, measures based on classroom observation. We discuss the implications and lessons learned from this work for the conceptualization, design, and use of artifact‐based instruments for measuring instructional practice in different contexts and for different purposes. Artifact‐based instruments may illuminate features of instruction not apparent even through direct classroom observation; moreover, the process of structured collection and reflection on artifacts may have value for professional development. However, their potential value and applicability on a larger scale depends on careful consideration of the match between the instrument and the model of instruction, the intended uses of the measures, and the aspects of classroom practice most amenable to reliable scoring through artifacts. We outline a research agenda for addressing unresolved questions and advancing theoretical and practical knowledge around the measurement of instructional practice. © 2011 Wiley Periodicals, Inc.

This article describes the development of an instrument to measure teachers’ knowledge of vocabulary development and instruction, the Teacher Knowledge of Vocabulary Survey (TKVS). This type of knowledge has become increasingly important as all classroom teachers are expected to help students meet language and literacy standards that include vocabulary acquisition. While a few studies have measured teacher knowledge of reading, there are no known instruments for measuring teachers’ knowledge of vocabulary development and instruction. However, vocabulary is a crucial determinant of reading comprehension and content area knowledge, particularly for English learners (Graves, August, & Mancilla-Martinez, 2013). Statements about vocabulary development and instruction were gathered from foundational texts, reviewed by subject matter experts, and researched in cognitive labs for possible inclusion as items in the TKVS. The survey’s 52 statements comprise 6 categories, including one section on vocabulary development, four sections on instruction, and one section on instruction specifically for English learners. Ratings of item difficulty by subject matter experts were then used to distinguish three levels of teacher knowledge of vocabulary: emergent, intermediate, and expert. Fifty teachers completed the TKVS, and their performance was found to correlate with the experts’ predicted difficulties of the items. Initial analyses provide evidence for the content and construct validity of the TKVS as a measure of teacher knowledge of vocabulary development and effective instruction. The discussion considers implications for the use of the instrument, including as a needs assessment or guide for professional development for both preservice and inservice teachers.  相似文献

Since the 1970s, many observation instruments have been constructed to map teachers’ general pedagogic competencies. However, few of these instruments focus on teachers’ subject-specific competencies. This study presents the development of the Framework for Analyzing the Teaching of Historical Contextualization (FAT-HC). This high-inference observation instrument focuses on history teachers’ competency in promoting historical contextualization in classrooms. The results of the study demonstrate the instrument’s content validity. Generalizability studies were conducted to further assess the instrument’s dimensionality and reliability by decomposing the instrument’s variance. A large proportion of the variance was explained by differences between observed teachers, and a small proportion of the variance was explained by lessons and observers, demonstrating the instrument’s reliability. Furthermore, a decision study was conducted to determine the optimal number of observers and lessons needed for a reliable scoring design. The developed instrument could be used to gain greater insight into history teachers’ subject-specific competencies and to focus teacher professionalization on teachers’ specific needs.  相似文献

The purpose of this study was to examine the experiences of preservice elementary teachers in a content-specific field-based experience with elementary science specialists. Data collected from electronic discussions, interviews, and observations in the field revealed preservice teachers experienced a wide range of instructional and assessment strategies in specialists’ classrooms, but failed to generalize aspects of the specialist model of science instruction to traditional models for delivery of science instruction at the elementary level. Implications for supporting preservice teachers’ learning to teach science through participation in a field experience with specialists are discussed.  相似文献

In an effort to improve student achievement at an urban high school, teachers and administrators developed a 5-part, schoolwide vocabulary plan. Over 4 years, teachers provided students with increased opportunities to read, read to their students, developed content-specific vocabulary instruction, taught students academic words, and focused on 5 words each week with a common prefix, suffix, or root. Over the 4 years, student achievement in vocabulary and reading comprehension improved in significant ways, both on reading assessments and state achievement tests.  相似文献

Instruments designed to measure teachers’ knowledge for teaching mathematics have been widely used to evaluate the impact of professional development and to investigate the role of teachers’ knowledge in teaching and student learning. These instruments assess a mixture of content knowledge and pedagogical content knowledge. However, little attention has been given to the content alignment between such instruments and curricular standards, particularly in regard to how content knowledge and pedagogical content knowledge items are distributed across mathematical topics. This article provides content maps for two widely used teacher assessment instruments in the USA relative to the widely adopted Common Core State Standards. This common reference enables comparisons of content alignment both between the instruments and between parallel forms within each instrument. The findings indicate that only a small number of items on both instruments are designed to capture teachers’ pedagogical content knowledge and that the majority of these items are focused on curricular topics in the later grades rather than in the early grades. Furthermore, some forms designed for use as pre- and post-assessment of professional development or teacher education are not parallel in terms of curricular topics, so estimates of teachers’ knowledge growth based on these forms may not mean what users assume. The implications of these findings for teacher educators and researchers who use teacher knowledge instruments are discussed.

This study aimed to develop and validate an instrument to assess the multidimensional nature of teacher self‐regulation. A nine‐factor structure was proposed: goal setting, intrinsic interest, performance goal orientation, mastery goal orientation, self‐instruction, emotional control, self‐evaluation, self‐reaction, and help‐seeking. Through a series of confirmatory factor analyses with different samples, this nine‐factor structure was supported. Reliability estimates were also satisfactory. Further validation evidence was provided through canonical correlation analysis between teacher self‐regulation and teachers’ sense of efficacy. Results indicated that the Teacher Self‐Regulation Scale can be utilised as a valid and reliable instrument to assess teachers’ self‐regulatory strategies.  相似文献

The so-called control-of-variables strategy (CVS) incorporates the important scientific reasoning skills of designing controlled experiments and interpreting experimental outcomes. As CVS is a prominent component of science standards appropriate assessment instruments are required to measure these scientific reasoning skills and to evaluate the impact of instruction on CVS development. A detailed review of existing CVS instruments suggests that they utilize different, and only a few of the four, critical CVS sub-skills in the item development. This study presents a new CVS assessment instrument (CVS Inventory, CVSI) and investigates the validity of student measures derived from this instrument utilizing Rasch analyses. The results indicate that the CVSI produces reliable and valid student measures with regard to CVS. Furthermore, the results show that the item difficulty depends on the CVS sub-skills utilized in item development, but not on the item content. Accordingly, previous instruments that are restricted to a few CVS sub-skills tend to over- or underestimate students’ CVS skills. In addition, these results indicate that students are able to use CVS as a domain general strategy in multiple content areas. Consequences for science instruction and assessment are discussed.  相似文献

Teachers' practices are directly tied to their beliefs or theories about instruction. The purpose of the present study was to develop an instrument to measure primary grade teachers' theoretical orientations about writing instruction, provide construct validation for this instrument, and describe teachers' beliefs about writing instruction in the early grades. Factor analysis of responses from a nationwide sample of primary grade teachers yielded three distinct dimensions, measuring beliefs about the role of explicit instruction, correctness in students' writing, and natural learning methods. The validity of the instrument was supported by findings showing that teachers' orientations were related to classroom writing practices in a predictable and reliable manner. Finally, most of the participating teachers emphasized both explicit instruction as well as incidental and informal methods of learning (i.e., the natural learning) in their theory of writing instruction for young children, while downplaying the importance of correctness in writing.  相似文献

Within a democratic and multicultural society, diversity is a reality, and differences between students are a fact which teachers have to deal with on a daily basis. Differentiated instruction aims to meet these differences in learning in order to provide all students with the best possible learning opportunities. However, to date no validated instruments exist to measure teachers’ perceptions of differentiated instruction and their related classroom practices. This study, therefore, examined the factor structure and reliability of the Differentiated Instruction Questionnaire, called the DI-Quest instrument. A list of 87 items was constructed, building on existing prevalent theoretical models of Differentiated Instruction (e.g. Tomlinson, 2014; Hall, 2002). An exploratory and confirmatory factor analysis was undertaken to investigate the factor structure of the questionnaire. As a result, five factors emerged: two factors related to the teachers’ philosophy of differentiated instruction (the teachers’ mindset and their ethical compass), two factors referred to the practical principles that teachers apply to differentiate (flexible grouping and output = input) and the last factor (differentiated instruction) covered the self-reported extent to which teachers differentiated their instruction related to three types of differences in learning (students’ interests, readiness and learning profile). As a result, the DI-Quest instrument entailed 31 items with a five-factor structure indicating a good fit (CFI = 0.919; TLI = 0.911; RMSEA = 0.041 [0.037–0.044 – 90% confidence interval, p(0.05) = 1.000]; SRMR = 0.048; χ2 = 5888.338, df = 465, p = 0.000). In addition, assuming theoretical relatedness between the factors, the validation of a DI-Quest model was empirically validated. We compared the model fit for two models by investigating which model had a lower BIC and AIC value and by comparing their chi square values. The best-fitting DI-Quest model showed four factors (teachers’ mindset, ethical compass, flexible grouping and output = input as dependent variables) functioning as significant predictors of the fifth factor (the self-reported adoption of Differentiated Instruction, which served as an independent variable). Moreover, this paper also discusses the psychometric properties of the DI-Quest instrument and the implications of the model for schools, educators and researchers.  相似文献

A methodology for studying change during instruction in content-specific cognitive processes is presented. The methodology borrows both from the cognitive mediational approach in instructional effectiveness research and the instructional approach in cognitive psychology research. It is argued that learning from instruction must be understood in terms of the way in which instruction changes the cognitive processes used to solve tasks. The methodology is illustrated by summarizing a project on instructing middle-school students in semantic processes for solving decimal-fraction problems. The benefits of the methodology, such as tracing the effects of instruction on performance change, are discussed.  相似文献

As a multi-disciplinary team of teacher educators (in English Language Arts, English as a Second Language/Foreign Language, science, and social studies), we consider how secondary pre-service teachers (PSTs) perceive content-area literacy integration through practitioner-research study of how PSTs constructed Quad Text Sets (QTS). Results indicated that PSTs envisioned QTS as a means to teach content-specific background knowledge, and to a lesser extent content-specific literacy and general literacy. Despite positive perceptions of QTS, some PSTs, particularly science PSTS, struggled to recognize literacy’s role in content-area classrooms. We explore how teacher educators can help PSTs incorporate literacy strategies into secondary classrooms.  相似文献

Computational thinking is one of the skills critical for successfully solving problems posed in a technology driven and complex society. The limited opportunities in school settings to help students develop computational thinking skills underscores the need for helping teachers integrate it in their practices. Besides developing the knowledge of technology, content, and pedagogy, teachers need to recognize the relevance of computational thinking to their teaching, a factor influencing their future practice with it. Drawing from the literature on problem-solving and TPACK framework, this paper discusses strategies, including content-specific examples, problem-solving nature of computational thinking, and the methods of teaching problem-solving for enabling teachers to make the connections between computational thinking and their practices.  相似文献

Heightened accountability pressures and an increased emphasis on teaching quality have directed scholarly attention to scrutinizing instruction, particularly with respect to issues of validity and reliability. However, these attempts have largely been directed toward “core” content areas and investigated generic or content-specific instructional aspects separately. Focusing on a less explored area, physical education, and concurrently attending to both instructional aspects, in this exploratory study, we examined whether the optimal lesson-rater combination needed to obtain reliable teaching-quality estimates differs depending on the type of instructional aspects considered. Data analysis of 147 lessons using generalizability theory suggested that either a 3-lesson-2-rater or a 4-lesson-1-rater combination yields sufficiently reliable estimates for nearly all dimensions examined (generic or content specific). Quality of student practice, however, required 11 lessons scored by 2 raters. These findings underline the importance of examining individual dimensions within a given observational instrument and the merit of carefully selecting and training raters.  相似文献

This article reports the development and application of two instruments for assessing science teachers’ pedagogical knowledge in the context of teaching higher‐order thinking: a Likert‐type research instrument, and an instrument that analyzes classroom observations. The rationale for developing these instruments and their main categories is described. One hundred and fifty Israeli science teachers replied to the Likert‐type questionnaire. Results show that biology teachers gained a significantly higher score than either physics or chemistry teachers, that junior high school teachers scored significantly higher than high school teachers, and that a significant negative correlation was found between final scores and teaching experience. Participants in the classroom observation study were 14 teachers who attended a one‐year professional development course for teaching higher‐order thinking. The instrument was sensitive in detecting progress in teachers’ pedagogical knowledge in several categories, such as: Frequency of tasks that required higher‐order thinking; The variety of thinking strategies that teachers addressed during their lessons; Engagement of students in metacognitive thinking; and Using the “language of thinking” in class. The implications of the findings for research and practice are described.  相似文献
