Learning how to write is a challenging process, typically developed in schools. Teachers’ practices in teaching writing, however, have been under researched. The aim of this study was to survey a sample of teachers from Portugal (n = 96) and Brazil (n = 99) about their practices for and perceptions about writing instruction. Teachers reported on time devoted to student writing and the teaching of writing, on their practices to promote students’ self-regulated writing, adaptations for less skilled writers, and their perceptions about writing and the teaching of writing. Findings from this survey raised concerns about the quality of writing instruction in both countries. Teachers reported little time devoted for writing and the teaching of writing in their classes. The majority of the teachers rarely used practices to promote students’ self-regulated writing or applied explicit teaching methods for writing instruction. Both Portuguese and Brazilian teachers perceived writing as a shared responsibility. Brazilian teachers, however, agreed with this perception more strongly. Portuguese teachers’ perception of the importance of writing for students’ academic and professional success was higher than the perceptions held by Brazilian teachers. A positive correlation was found between teachers’ preparation to teach writing and their practices to promote students’ self-regulated writing. The implications of these findings are discussed.  相似文献

Research on teachers’ professionalism and professional development has increased in the last two decades. A main focus of this line of research has been the cognitive component of teacher professionalism, i.e., professional knowledge. Most of the previous studies on teacher knowledge—such as the Learning Mathematics for Teaching (LMT) (Hill et al. 2004), the Professional Competence of Teachers, Cognitively Activating Instruction, and Development of Students´ Mathematical Literacy (COACTIV) (Baumert et al. 2010), and the Mathematics Teaching in the 21st Century (MT21) (Schmidt et al. 2007) studies—have been conducted in the field of mathematics teachers’ pedagogical content knowledge (PCK) and content knowledge (CK). There have been few comparable studies conducted with science teachers, especially biology teachers. To fill the gap, this study examines the development and use of instruments to measure biology teachers’ CK and PCK. In particular, this study describes a method to develop reliable, objective, and valid instruments measuring teachers’ CK and PCK in four steps by the use of empirical data of students. Additionally, the study explores whether CK and PCK might be measured as separate knowledge categories by using a paper-and-pencil test. This paper presents a theoretical model that guides test development and provides steps to develop and validate the instruments. Details are also provided regarding the computation of the Rasch scale score measures for 158 biology teachers. The results indicate that the instruments measured teachers’ CK and PCK in an objective, valid, and reliable way. This suggests that the new instruments can be used in combination with classroom observations to examine teaching quality and further its relation to student learning.  相似文献

Some researchers have investigated teachers’ pedagogical content knowledge (PCK) concerning scientific practices. However, from a review of the literature on the PCK construct and its use for characterising teachers’ knowledge of scientific practices, as well as from a discussion of possible interpretations that emerge from the derived construct PCK of scientific practices, this paper discusses the current complexity of PCK from an analysis of the paths that have been taken in the last few decades. From this, we (i) raise some points and questions aiming at fostering reflections on the use of the PCK construct to characterise teachers’ knowledge related to scientific practices and (ii) emphasise the need to think about alternative models for this purpose. Thus, one of the contributions of this paper is to emphasise the need for further studies aiming at characterising teaching knowledge in domains of scientific practices.

With the goal of producing scientifically literate citizens who are able to make informed decisions and reason critically when science intersects with their everyday lives, the National Research Council (NRC) has produced two recent documents that call for a new approach to K-12 science education that is based on scientific practices, crosscutting concepts, and disciplinary core ideas. These documents will potentially influence future state standards and K-12 curricula. Teachers will need support in order to teach science using a practices based approach, particularly if they do not have strong science backgrounds, which is often the case with elementary teachers. This study investigates one cohort (n = 19) of preservice elementary teachers’ ideas about scientific practices, as developed in a one-semester elementary science teaching methods course. The course focused on eight particular scientific practices, as defined by the National Research Council’s A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas (2012). Participants’ written reflections, lesson plans and annotated teaching videos were analyzed in fine detail to better understand their ideas about what it means to engage in each of the practices. The findings suggest that preservice elementary teachers hold promising ideas about scientific practices (such as an emphasis on argumentation and communication between scientists, critical thinking, and answering and asking questions as the goal of science) as well as problematic ideas (including confusion over the purpose of modeling and the process of analysis, and conflating argumentation and explanation building). These results highlight the strengths and limitations of using the Framework (NRC 2012) as an instructional text and the difficulties of differentiating between preservice teachers’ content knowledge about doing the practices and their pedagogical knowledge about teaching the practices.  相似文献

The relationship between 2nd and 3rd grade teachers’ linguistic knowledge and spelling instructional practices and their students’ spelling gains from fall to spring was examined. Second grade (N = 16) and 3rd grade (N = 16) teachers were administered an instructional practices survey and a linguistic knowledge test. Total scores on the two instruments were not significantly related (r = 0.20), indicating two different constructs. Students (N = 331 2nd graders, N = 305 3rd graders) completed a 40 item spelling dictation test in the fall and spring. HLM analyses were conducted on subsamples of weaker spellers (Ns = 226 2nd graders and 50 3rd graders) who spelled fewer than 20 words correctly on the pretest. Limiting the sample to weaker spellers eliminated ceiling effects on pre- to posttest gains. Results revealed that 2nd grade teachers’ linguistic knowledge of phonemic units in words, their teaching of spelling strategies, the time they spent in weekly spelling instruction, and the greater the number of weaker spellers in their classrooms, were significant predictors of weaker spellers’ improvement in spelling. For 3rd grade teachers, HLM analyses were not significant perhaps due to lack of power. However, 3rd grade teachers’ phonemic knowledge was significantly correlated with weaker spellers’ gain scores. Results while correlational provide tentative support for the conclusion that teachers who are more knowledgeable about phonemes in words and who utilize more effective, research based spelling instruction are more successful in teaching spelling to weaker spellers.  相似文献

The nature of science (NOS) has become a central goal of science education in many countries. This study refers to a developmental work research program, in which four fifth-grade elementary in-service teachers participated. It aimed to improve their understandings of NOS and their abilities to teach it effectively to their students. The 1-year-long, 2012–2013, program consisted of a series of activities to support teachers to develop their pedagogical content knowledge of NOS. In order to accomplish our goal, we enabled teacher-researchers to analyze their own discourse practices and to trace evidence of effective NOS teaching. Many studies indicate the importance of examining teachers’ discussions about science in the classroom, since it is teachers’ understanding of NOS reflected in these discussions that will have a vital impact on students’ learning. Our proposal is based on the assumption that reflecting on the ways people form meanings enables us to examine and seek alternative ways to communicate aspects of NOS during science lessons. The analysis of discourse data, which has been carried out with the teacher-researchers’ active participation, indicated that initially only a few aspects of NOS were implicitly incorporated in teacher-researchers’ instruction. As the program evolved, all teacher-researchers presented more informed views on targeted NOS aspects. On the whole, our discourse-focused professional development program with its participatory, explicit, and reflective character indicated the importance of involving teacher-researchers in analyzing their own talk. It is this involvement that results in obtaining a valuable awareness of aspects concerning pedagogical content knowledge of NOS teaching.  相似文献

The most important benefits of international comparisons are the indications that make hidden national characteristics visible and shed new light on the system in each country. From a comparative perspective, this article explores what Swedish and Norwegian preschool teachers emphasise as important to preschool student teachers about preschool as an arena for children’s language learning. The theoretical framework of the study is based on ecological system theories (Bronfenbrenner in The ecology of human development, Harvard University Press, Cambridge, 1979; Bronfenbrenner in Dev Psychology 22(6):723–742, 1986) and socio-cultural theories concerning language learning (Vygotsky in Thought and language, MIT Press, Cambridge, 1986). The data are produced through interviews with 69 Swedish and 35 Norwegian preschool teachers. The analyses focused on what the preschool teachers stated to be the most important elements to work with concerning children’s language learning, how and why they worked like this, and what rationales may have led to their pedagogy. The two countries seem quite alike in terms of the values embedded in early childhood education and political ideas concerning a rich childhood based on play and democratic ideals. By comparing the two countries, the results reveal differences that can lead to a deeper knowledge of cultural concepts that are often taken for granted, such as pedagogical approaches, and how these create different conditions for children’s preschool language learning.  相似文献

Our study uses data from the Wabash National Study of Liberal Arts Education to interrogate the affinity disciplines hypothesis through students’ perceptions of faculty use of six of Chickering and Gamson’s (AAHE Bull 39(7):3–7, 1987) principles of good practice for undergraduate education. We created a proportional scale based on Biglan’s (J Appl Psychol 57(3):195–203, 1973) classification of paradigmatic development (with higher scores on the scale corresponding to students taking a higher proportion of courses in ‘hard’ fields compared to ‘soft’ fields), our study tests differences by the paradigmatic development of the disciplines or fields in which students take their courses within the first year of college. Our findings suggest that as paradigmatic development increases (toward a higher proportion of courses taken in hard disciplines), student perceptions of both faculty use of prompt feedback and faculty use of high expectations/academic challenge decrease, while student perceptions of cooperative learning increase. Further, no statistically significant differences were found between the paradigmatic development of fields in which students’ take their courses and students’ perceptions of faculty use of student-faculty contact, active and collaborative learning, or teaching clarity and organization. This study replicates the findings from Braxton et al. (Res High Educ 39(3):299–318, 1998) using student-level rather than faculty-level reports of faculty use of good teaching practices.  相似文献

This study investigated the effects of teachers’ use of focus questions on students’ knowledge structures and classroom teaching-learning process by re-analyzing selected data from a quasi-experimental pre-post video study (Wadouh, 2007). Focus questions are content-related anchoring questions highlighting the key content taught in individual lessons (Forbes & Davis, 2010). In Wadouh’ study, students answered a knowledge test before and after the lesson on “blood and the circulatory system” and one lesson per teacher was videotaped to investigate teaching practices in grade 9 biology classrooms. Students also completed a post-unit concept mapping exercise and a motivation-interest questionnaire. In this study, 30 lesson videos selected from 47 were re-analyzed for teachers’ use of focus questions—no focus questions, non-specific or simple focus questions, and specific and challenging focus questions. Individual students’ scores in the concept mapping exercise were aggregated as students’ topic-related knowledge structure. Multilevel analyses revealed a significant positive effect of teachers’ use of specific and challenging focus questions on students’ topic-related knowledge structure. Furthermore, a comparative case analysis of the classroom teaching-learning process was conducted in four lessons where teachers used specific and challenging focus questions in two of the lessons and non-specific or simple focus questions in the other two lessons. The findings indicate that specific and challenging focus questions anchored lessons on students’ co-construction of scientific explanations by activating their pre-instructional ideas, whereas non-specific or simple focus questions anchored lessons on their accumulation of canonical scientific knowledge. This study’s limitations and implications for teacher education reform are discussed.  相似文献

Because of ever stricter standards of accountability, science teachers are under an increasing and unrelenting pressure to demonstrate the effects of their teaching on student learning. Econometric perspectives of teacher quality have become normative in assessment of teachers’ work for accountability purposes. These perspectives seek to normalize some key ontological assumptions about teachers and teaching, and thus play an important role in shaping our understanding of the work science teachers do as teachers in their classrooms. In this conceptual paper I examine the ontology of science teaching as embedded in econometric perspectives of teacher quality. Based on Foucault’s articulation of neoliberalism as a discourse of governmentality in his ‘The Birth of Biopolitics’ lectures, I suggest that this ontology corresponds well with the strong and substantivist ontology of work under neoliberalism, and thus could potentially be seen as reflection of the influence of neoliberal ideas in education. Implications of the mainstreaming of an ontology of teaching that is compatible with neoliberalism can be seen in increasing marketization of teaching, ‘teaching evangelism’, and impoverished notions of learning and teaching. A shift of focus from teacher quality to quality of teaching and building conceptual models of teaching based on relational ontologies deserve to be explored as important steps in preserving critical and socially just conceptions of science teaching in neoliberal times.  相似文献

3D printing technology is a powerful educational tool that can promote integrative STEM education by connecting engineering, technology, and applications of science concepts. Yet, research on the integration of 3D printing technology in formal educational contexts is extremely limited. This study engaged preservice elementary teachers (N?=?42) in a 3D Printing Science Project that modeled a science experiment in the elementary classroom on why things float or sink using 3D printed boats. The goal was to explore how collaborative 3D printing inquiry-based learning experiences affected preservice teachers’ science teaching self-efficacy beliefs, anxiety toward teaching science, interest in science, perceived competence in K-3 technology and engineering science standards, and science content knowledge. The 3D printing project intervention significantly decreased participants’ science teaching anxiety and improved their science teaching efficacy, science interest, and perceived competence in K-3 technological and engineering design science standards. Moreover, an analysis of students’ project reflections and boat designs provided an insight into their collaborative 3D modeling design experiences. The study makes a contribution to the scarce body of knowledge on how teacher preparation programs can utilize 3D printing technology as a means of preparing prospective teachers to implement the recently adopted engineering and technology standards in K-12 science education.  相似文献

Current reform in science education calls for teachers to understand student thinking within a lesson to effectively address students’ needs (NRC in A framework for K-12 science education: practices, crosscutting concepts, and core ideas. National Academy Press, Washington, DC, 2012; NRC in Guide to implementing the Next Generation Science Standards. The National Academies Press, Washington, DC, 2015). This study investigates how to scaffold preservice teachers with learning to attend to students’ thinking for the purpose of guiding curricular decisions. The study focuses on one team teaching a science unit during their early field experience. We sought to understand how participants’ thoughts and abilities changed through participation in a moderated community of practice using video of their own teaching as a reflective tool. We examined how these changes affected both their classroom practice and their decision-making for future lessons. Evidence shows growth in participants’ ability to identify opportunities to elicit, assess, and use students’ thinking to guide instructional decisions. Implications for use of the approach used in this study to begin developing novice teachers’ pedagogical content knowledge for teaching science are discussed.  相似文献

In order to teach mathematics effectively, mathematics teachers need to have a sound mathematical knowledge, but what constitutes sound mathematical knowledge for teaching is subject to debate. This paper is an attempt to unpack what constitutes teacher knowledge of the concept of a function which is a unifying idea in the mathematics curriculum. The central components of the framework, which will be elaborated on in this paper, are: teachers’ subject matter knowledge, teachers’ pedagogical content knowledge, teachers’ technological pedagogical knowledge, technological content knowledge, and technological pedagogical content knowledge in relation to the concept of a function. The framework is informed by Shulman’s (Educational Researcher 15:4–14, 1986) Types of Teachers Knowledge Framework, Ball, Bass & Hill 29:14–17, 20–22, 43–46 (2005) Mathematical Knowledge for Teaching Framework, and Mishra & Koehler’s (Teachers College Record 108:1017–1054, 2006) Technological Pedagogical Content Knowledge (TPACK) framework.  相似文献

This pilot study investigates the impact of a 2-week professional development Summer Institute on PK-3 teachers’ knowledge and practices. This Summer Institute is a component of [program], a large-scale early-childhood science project that aims to transform PK-3 science teaching. The mixed-methods study examined concept maps, lesson plans, and classroom observations to measure possible changes in PK-3 teachers’ science content knowledge and classroom practice from 11 teachers who attended the 2014 Summer Institute. Analysis of the concept maps demonstrated statistically significant growth in teachers’ science content knowledge. Analysis of teachers’ lesson plans demonstrated that the teachers could design high quality science inquiry lessons aligned to the Next Generation Science Standards following the professional development. Finally, examination of teachers’ pre- and post-Summer Institute videotaped inquiry lessons showed evidence that teachers were incorporating new inquiry practices into their teaching, especially regarding classroom discourse. Our results suggest that an immersive inquiry experience is effective at beginning a shift towards reform-aligned science and engineering instruction but that early elementary educators require additional support for full mastery.  相似文献

The intent of national efforts to frame science education standards is to promote students’ development of scientific practices and conceptual understanding for their future role as scientifically literate citizens (NRC 2012). A guiding principle of science education reform is that all students receive equitable opportunities to engage in rigorous science learning. Yet, implementation of science education reform depends on teachers’ instructional decisions. In urban schools serving students primarily from poor, diverse communities, teachers typically face obstacles in providing reform-based science due to limited resources and accountability pressures, as well as a culture of teacher-directed pedagogy, and deficit views of students. The purpose of this qualitative research was to study two white, fourth grade teachers from high-poverty urban schools, who were identified as transforming their science teaching and to investigate how their beliefs, knowledge bases, and resources shaped their planning for reform-based science. Using the Shavelson and Stern’s decision model for teacher planning to analyze evidence gathered from interviews, documents, planning meetings, and lesson observations, the findings indicated their planning for scientific practices was influenced by the type and extent of professional development each received, each teacher’s beliefs about their students and their background, and the mission and learning environment each teacher envisioned for the reform to serve their students. The results provided specific insights into factors that impacted their planning in high-poverty urban schools and indicated considerations for those in similar contexts to promote teachers’ planning for equitable science learning opportunities by all students.  相似文献

Mentoring is too important to be left to chance (Ganser, 1996 Ganser, T. 1996. What do mentors say about mentoring?. Journal of Staff Development, 17(3): 3639.  [Google Scholar]), yet mentoring expertise of teachers varies widely, which may present inequities for developing preservice teachers' practices. Five factors for mentoring have been identified herein: personal attributes, system requirements, pedagogical knowledge, modelling, and feedback, and items associated with each factor have also been justified in context of the literature. An original, literature‐based survey instrument gathered 446 preservice teachers' perceptions of their mentoring for primary teaching. Data were analysed within the above‐mentioned five factors with 331 final‐year preservice teachers from nine Australian universities responding to their mentoring for science teaching and 115 final‐year preservice teachers from an urban university responding to their mentoring for mathematics teaching. Results indicated similar Cronbach alpha scores on each of the five factors for primary science and mathematics teaching; however percentages and mean scores on attributes and practices aligned with each factor were considerably higher for mentoring mathematics teaching compared with science teaching.  相似文献

This study examines gender differences of teachers on their mathematical knowledge for teaching in the context of single-sex classrooms in Saudi Arabia. A translated version of the Mathematical Knowledge for Teaching (MKT) instrument (Learning Mathematics for Teaching [LMT], 2008) in Number and Operation Content Knowledge (CK) and Knowledge of Content and Student (KCS) scales were administered to 197 teachers (146 male and 51 female). Two-sample t test and multiple regression were conducted to compare the two groups and test the effect of teacher background variables. Female teachers significantly scored better than their male counterpart. Gender, years of teaching experience, and specialization significantly predicted teachers’ content knowledge, F(3, 187) = 13.180, explaining 41.8 % of the variance. Only gender and specialization significantly predicted teachers’ knowledge of content and student, F(2, 191) = 6.335, explaining 24.9 % of the variance. Further comparing items in the MKT instrument where female teachers outperformed male teachers confirmed that female teachers were better in attending to the content knowledge in the context of student’s learning.  相似文献

For beginning teachers to make the transition to full professional membership they need to increase their professional knowledge of the art and science of teaching. This paper explores the difference in knowledge growth between beginning teachers who commence teaching in fragmented teaching situations in the first two years of teaching, and their colleagues who have stable, secure and continuing employment during this time. This paper argues that the employment context in which beginning teachers take up their profession has a significant, but hitherto largely unacknowledged, effect on the capacity of teachers to develop the craft of teaching (Elbaz, 1983 Elbaz, F. 1983. Teacher thinking: A study of practical knowledge, London: Croom Helm.  [Google Scholar]); on their continuing commitment to the profession; and on their self-confidence and self-image as teachers It is concluded that long-term, secure employment in one school, with full responsibility for a class of students and access to effective mentoring, is necessary if beginning teachers are to move beyond ‘survival’ to developing competency in the first two years of teaching.  相似文献

Worldwide there has been a range of initiatives in the area of standards for teachers as part of a discourse of professionalism. In Australia there are a plethora of standards: state and territory frameworks, generic and subject‐specific, systemic and cross‐systemic, for pre‐service, beginning and experienced teachers. Little has been written as to how teacher education programs are responding to the standards agenda. This paper positions standards as integral to the recontextualizing field (Bernstein, 2000 Bernstein B 2000 Pedagogy, symbolic control and identity: theory, research, critique (Lanham, Rowman & Littlefield)  [Google Scholar]) for teacher educators and their programs. Using Bernsteinian concepts of fields, identities and framing, we compare the responses of two physical education teacher education programs to their state's standards imperatives. The authors conclude that the academic orientation of the university, together with the framing of the standards, affect the degree of programmatic change it will undertake in response to the changes in teacher certification standards.  相似文献

In recent years, inquiry-based science instruction has become widely advocated in science education standards in many countries and, hence, in teacher preparation programmes. Nevertheless, in practice, one finds a wide variety of science instructional approaches. In South Africa, as in many countries, there is also a great disparity in school demographic situations, which can also affect teaching practices. This study investigated the pedagogical orientations of in-service physical sciences teachers at a diversity of schools in South Africa. Assessment items in a Pedagogy of Science Teaching Test (POSTT) were used to identify teachers’ science teaching orientations, and reasons for pedagogical choices were probed in interviews. The findings reveal remarkable differences between the orientations of teachers at disadvantaged township schools and teachers at more privileged suburban schools. We found that teachers at township schools have a strong ‘active direct’ teaching orientation overall, involving direct exposition of the science followed by confirmatory practical work, while teachers at suburban schools exhibit a guided inquiry orientation, with concepts being developed via a guided exploration phase. The study identified contextual factors such as class size, availability of resources, teacher competence and confidence, time constraints, student ability, school culture and parents’ expectations as influencing the methods adopted by teachers. In view of the recent imperative for inquiry-based learning in the new South African curriculum, this study affirms the context specificity of curriculum implementation (Bybee 1993) and suggests situational factors beyond the curriculum mandate that need to be addressed to achieve successful inquiry-based classroom instruction in science.  相似文献
