A critical aspect of teacher education is gaining pedagogical content knowledge of how to teach science for conceptual understanding. Given the time limitations of college methods courses, it is difficult to touch on more than a fraction of the science topics potentially taught across grades K-8, particularly in the context of relevant pedagogies. This research and development work centers on constructing a formative assessment resource to help expose pre-service teachers to a greater number of science topics within teaching episodes using various modes of instruction. To this end, 100 problem-based, science pedagogy assessment items were developed via expert group discussions and pilot testing. Each item contains a classroom vignette followed by response choices carefully crafted to include four basic pedagogies (didactic direct, active direct, guided inquiry, and open inquiry). The brief but numerous items allow a substantial increase in the number of science topics that pre-service students may consider. The intention is that students and teachers will be able to share and discuss particular responses to individual items, or else record their responses to collections of items and thereby create a snapshot profile of their teaching orientations. Subsets of items were piloted with students in pre-service science methods courses, and the quantitative results of student responses were spread sufficiently to suggest that the items can be effective for their intended purpose. 相似文献

This study investigated a professional development model designed to improve teachers' inquiry teaching efficacy as well as the quality of their inquiry instruction through engaging teachers in practice-teaching and reflection sessions. The programme began with a two-week summer Institute focused on both inquiry pedagogy and science content and continued with academic year support for participants' inquiry implementation. An inquiry teaching efficacy instrument was administered 3 times to 25 teacher participants to gauge changes in their personal self-efficacy and outcome expectancy across 5 essential features of classroom inquiry. To examine actual practices, pre/post classroom observations of the teachers' inquiry enactments were evaluated using a quality of inquiry observation protocol. Following the summer Institute, teachers had statistically significant increases in their self-efficacy for teaching inquiry in four of the five essential features and increases in one of the five essential features for outcome expectancy. Teachers' quality of inquiry teaching also increased after the professional development programme. We discuss implications of this PD model for moving teachers towards implementation of new instructional techniques as well as the influence of a supportive school community on teachers’ efficacy with inquiry instruction. 相似文献

A survey instrument was developed and administered to 1,222 K-12 mathematics and science teachers to measure their beliefs
about and use of inquiry in the classroom. Four variables (grade level taught, content area taught, level of support received,
and self-efficacy for teaching inquiry) were significantly correlated to two dependent variables, percentage of time that
students are engaged in inquiry during a typical lesson and the perceived ideal percentage of instructional time that should
be devoted to inquiry. Specifically, elementary school teachers reported using inquiry-based practices more than either middle-school
or high-school teachers; similarly, elementary-school teachers believed such practices should be used more often. All groups,
however, reported believing in an ideal percentage of time devoted to inquiry instruction that was significantly greater than
their reported percentage of time actually spent on inquiry instruction. A disordinal effect was found between grade level
taught and content area taught; at the elementary level, science teachers reported both an ideal and actual percentage of
time on inquiry higher than those reported by the math teachers, while at the high school level math teachers reported both
an ideal and actual percentage of time on inquiry higher than those reported by the science teachers. No correlations were
found between typical and ideal percentage of time devoted to inquiry and subject matter content knowledge training, gender,
years of teaching experience, or maximum degree earned. 相似文献

The study examined US elementary teachers’ knowledge and practices in four key domains of science instruction with English language learning (ELL) students. The four domains included: (1) teachers’ knowledge of science content, (2) teaching practices to promote scientific understanding, (3) teaching practices to promote scientific inquiry, and (4) teaching practices to support English language development during science instruction. The study was part of a larger five‐year research and development intervention aimed at promoting science and literacy achievement of ELL students in urban elementary schools. It involved 32 third grade, 21 fourth grade, and 17 fifth grade teachers participating in the first‐year implementation of the intervention. Based on teachers’ questionnaire responses and classroom observation ratings, results indicated that (1) teachers’ knowledge and practices were within the bounds of acceptability but short of reform‐oriented practices and (2) grade‐level differences existed, especially between Grades 3 and 5. 相似文献

This paper introduces a novel strategy for teaching physics: using the Nobel Physics Prize as an organizational theme for
high school or even first year university physics, bringing together history, social contexts of science, and central themes
in modern physics. The idea underlying the strategy is that the glamour and glitter of the Nobel Prize story may attract and
motivate high school students to open-up to scientific topics and thus be spurred to pursue science. The two major arguments
for the method are that if presented in story form Nobel Prizes naturally incorporate the philosophical and historical aspects
of science and therefore enable teaching about science as well as teaching science itself; and that such instruction implements
case-based teaching principles, which is how humans naturally think, learn, and remember. Finally, the paper presents the
storycase of the Nobel Prize Einstein received for his discovery of the law of the photoelectric effect as a concrete illustration
of classroom implementation. 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

In this study, we investigated the impact of teaming school-based instructional coaches with science or mathematics middle school teachers to build a community of practice around inquiry instruction. This professional development model began with a 2-week summer institute and continued with four follow-up sessions during the academic school year for the teacher and instructional coach participants. The teachers’ participation in this professional development program with (1) content instruction through inquiry lessons, (2) practice teaching to middle school students, and (3) coach-led reflection improved their understanding of inquiry-based practices and the quality of their classroom inquiry implementation. Professional development experiences that prepare teachers and coaches simultaneously in inquiry and content may help build a shared language for reform and accelerate inquiry instructional changes. 相似文献

The currency, relevancy and changing nature of science makes it a natural topic of focus for mass media outlets. Science teachers
and students can capitalize on this wealth of scientific information to explore socio-scientific and sustainability issues;
however, without a lens on how those media are created and how representations of science are constructed through media, the
use of mass media in the science classroom may be risky. Limited research has explored how science teachers naturally use
mass media to explore scientific issues in the classroom or how mass media is used to address potential overlaps between socio-scientific-issue
based instruction and education for sustainability. This naturalistic study investigated the reported and actual classroom
uses of mass media by secondary science teachers’ to explore socio-scientific and sustainability issues as well as the extent
to which their instructional approaches did or did not overlap with frameworks for SSI-based instruction, education for sustainability,
and media literacy education. The results of this study suggest that secondary science teachers use mass media to explore
socio-scientific and sustainability issues, but their use of frameworks aligned with SSI-based, education for sustainability,
and media literacy education was limited. This paper provides suggestions for how we, as science educators and researchers,
can advance a teaching and learning agenda for encouraging instruction that more fully utilizes the potential of mass media
to explore socio-scientific issues in line with perspectives from education for sustainability. 相似文献

The purpose of this study is to examine the effect of state-mandated policy, emphasizing control through performance-based instruction and student test scores as the basis for determining school accreditation, on the teaching and learning of science. The intended consequence of instigating the rational theory of management by one state is to improve their current level of student literacy. However, some contend that the implementation of the policy has results that are not intended. The identification of the tension between the intended and unintended results of centralized policy making is the basis for examining a specific case in which the rational model is implemented. One hundred and sixty-five seventh-grade science students and four teachers are participants in the study. Qualitative analysis is the research methodology used as a means to provide detailed information about the contextual nature of the classroom processes. The intention is to identify and describe features of the behavior setting that influence the behavior of the teachers and their students. Three assertions generated during the field work were: Teachers redefine the goals of science instruction as the acquisition of facts and isolated skills, teachers alter their usual instructional behavior to implement uniform instructional procedures, and the teacher/student classroom interaction constrains students' opportunities to learn science. The implications of the study indicate that the state-mandated policy has results that are in opposition to the intended results. Instead of improving the practices of teachers, the implementation of the policy constrains and routinizes the teachers' behavior, causing them to violate their own standards of good teaching. They feel pressured to “get through” the materials so students will score well on tests. The classroom interaction is structured in such a way as to inhibit students from asking questions of their own. As a result, students' opportunity to express curiosity and inquiry—central processes in scientific thinking—are constrained. These unintended consequences of the implemented state policy, instead of improving science teaching and learning, continue to reduce science instruction to the literal comprehension of isolated facts and skills. 相似文献

Although the goal of developing school students’ understanding of nature of science (NOS) has long been advocated, there is still a lack of research that focuses on probing how science teachers, a kind of major stakeholder in NOS instruction, perceive the values of teaching NOS. Through semi-structured interviews, this study investigated the views of 15 Hong Kong in-service senior secondary science teachers about the values of teaching NOS. These values as perceived by the teachers fall into two types. The first type is related to students’ learning of science in the classroom and involves: (i) facilitating the study of subject knowledge, (ii) increasing the interest in learning science, (iii) supporting the conduct of scientific inquiry, (iv) meeting the needs of public examinations, and (v) fulfilling the requirement of learning science. The second type goes beyond learning science and includes (i) developing thinking skills, (ii) cultivating scientific ethics in students, and (iii) supporting the participation in public decisions on socioscientific issues. Although rich relationships were perceived by these teachers between NOS instruction and students’ learning of science, few values were stated from broad social and cultural perspectives. Suggestions are made about developing teachers’ views of the values of teaching NOS so as to influence their intention of teaching it. 相似文献

This study examined the geologic and evolutionary subject matter and views of inquiry and nature of science (NOS) of a group of 5th–9th grade teachers, and a comparison group, before and after participating in an inquiry-based professional development (PD) experience. Project teachers participated in an intensive, week-long, resident institute where they learned about geology, evolutionary concepts, NOS, and inquiry while engaging in an authentic scientific investigation. They were also given support in how to teach these topics using an inquiry-based approach. Analyses of data indicate that project teachers showed greater gains in subject matter than comparison teachers and the relative change was significantly different statistically. Furthermore, most project teachers demonstrated a shift from less informed to more informed views of inquiry and NOS and the relative change between participant and comparison teachers was significantly different statistically. These gains are promising because they suggest that short-term and intensive PD can support teachers in enhancing their knowledge and views. Moreover, analysis of post-programme questionnaires and interviews indicated that supporting teachers in reflecting on the relationship between their former classroom teaching practice, and new knowledge acquired during PD, may be an important link in enhancing teacher knowledge and supporting change in practice. This suggests that enhanced knowledge and views may not be the only factor contributing to changing one's practice. The study points to the importance of reflection in promoting teacher change. Results from this study add insights to supporting teachers in enacting inquiry-based instruction and teaching about NOS in their classrooms. 相似文献

Enactment of scientific inquiry in classroom has attracted a great attention of science educators around the world. In this study, we examined two competent teachers’ (one Grade 9 chemistry teacher and one Grade 4 science teacher) enactment of scientific inquiry in selected teaching units to reveal the characteristics of enacted inquiry at different grade levels by analyzing lesson sequence videos. The coding schemes for enacted inquiry consist of ontological properties and instructional practices. Pre-topic and post-topic teacher interviews and the two teachers’ responses to a questionnaire were adopted to identify the factors influencing teacher’s enactment. The results indicate that the two case teachers’ enactment involved a range of inquiry activities. The enacted inquiry at fourth-grade level covered all the inquiry elements, tending to engage students in the whole procedure of inquiry. The ninth-grade chemistry class placed emphasis on the elements “making plans” to solve problems in authentic context. Important factors influencing the enactment include teacher’s understanding about scientific inquiry, textbooks, assessment, students and resource. Implications for inquiry enactment and instruction improvement have been provided. 相似文献

This study assessed the influence of a 3‐year professional development program on elementary teachers' views of nature of science (NOS), instructional practice to promote students' appropriate NOS views, and the influence of participants' instruction on elementary student NOS views. Using the VNOS‐B and associated interviews the researchers tracked the changes in NOS views of teacher participants throughout the professional development program. The teachers participated in explicit–reflective activities, embedded in a program that emphasized scientific inquiry and inquiry‐based instruction, to help them improve their own elementary students' views of NOS. Elementary students were interviewed using the VNOS‐D to track changes in their NOS views, using classroom observations to note teacher influences on student ideas. Analysis of the VNOS‐B and VNOS‐D showed that teachers and most grades of elementary students showed positive changes in their views of NOS. The teachers also improved in their science pedagogy, as evidenced by analysis of their teaching. Implications for teacher professional development programs are made. © 2006 Wiley Periodicals, Inc.

ABSTRACTThis study used an experimental, pretest-posttest control group design to investigate whether participation in a large-scale inquiry project would improve primary teachers’ attitudes towards teaching science and towards conducting inquiry. The inquiry project positively affected several elements of teachers’ attitudes. Teachers felt less anxious about teaching science and felt less dependent on contextual factors compared to the control group. With regard to attitude towards conducting inquiry, teachers felt less anxious and more able to conduct an inquiry project. There were no effects on other attitude components, such as self-efficacy beliefs or relevance beliefs, or on self-reported science teaching behaviour. These results indicate that practitioner research may have a partially positive effect on teachers’ attitudes, but that it may not be sufficient to fully change primary teachers’ attitudes and their actual science teaching behaviour. In comparison, a previous study showed that attitude-focused professional development in science education has a more profound impact on primary teachers’ attitudes and science teaching behaviour. In our view, future interventions aiming to stimulate science teaching should combine both approaches, an explicit focus on attitude change together with familiarisation with inquiry, in order to improve primary teachers’ attitudes and classroom practices. 相似文献

Using the National Research Council's inquiry continuum framework, we use a multiple-case study research design to investigate the teacher- and student-directedness of elementary preservice teachers’ planned and enacted science lessons and their pedagogical reasoning about science instruction during a semester-long science methods course. Our specific research questions were (1) What ideas do elementary preservice teachers bring to a science teaching methods course about the inquiry continuum? and (2) How do their ideas about the inquiry continuum change over the course of the semester through engaging in planning, enactment, and reflection upon science instruction? Participants’ course artifacts (journals, reflective teaching assignments, and lesson plan rationales), interviews, and field observations of their enacted science lessons served as data for this study. Findings show that although the preservice teachers began the semester defining inquiry as highly student-directed, their ideas and definitions broadened over the course of the semester to include and embrace more teacher-directed forms of inquiry. Their early science lessons were more student-directed but, as they encountered challenges engaging in inquiry-based instruction and increasingly emphasized students’ learning needs, they began to plan and enact lessons that were more teacher-directed. Teacher education programs need to explicitly emphasize these variations of inquiry as a core component of supporting preservice teachers’ learning to teach science as inquiry. 相似文献
