Around the world, there have been curricula reforms involving the incorporation of the inquiry-based teaching and learning strategy in secondary school science education in general and in practical work in particular. Research in inquiry-based practical work (IBPW) has focused, for example, on aspects of the strategy itself, on teacher professional development, and on classroom teaching and learning based on the strategy. However, the question of the extent to which teaching practices linked to the implementation of practical work are actually inquiry-based, was still to be answered. To draw on the answer to this question to inform professional development practice and research, we focused on the case of physical sciences classrooms in two resource-constrained South African schools. In this regard, we used a conceptual framework based on the Interconnected Model of Teachers' Professional Growth and including a framework of teaching practices. In the data collection, we used a multimethod case study approach and to analyze the data, we combined the inductive and deductive approaches in thematic analysis. The results show that in the initiation, planning, and classroom implementation phases of practical work, many of the teaching practices of participants were inconsistent with inquiry-based teaching and learning, although some other practices were consistent with this type of teaching and learning. At the same time, some of the consistent practices were at a rather low level of implementation. We have discussed the theory-, practice-, and research-based implications of these results, in relation to the implementation of IBPW in resource-constrained physical sciences classrooms in South Africa and internationally. 相似文献

When students collaboratively design and build artifacts that require relevant understanding and application of science, many aspects of scientific literacy are developed. Design-based inquiry (DBI) is one such pedagogy that can serve these desired goals of science education well. Focusing on a Projectile Science curriculum previously found to be implemented with satisfactory fidelity, we investigate the many hidden challenges when using DBI with Grade 8 students from one school in Singapore. A case study method was used to analyze video recordings of DBI lessons conducted over 10 weeks, project presentations, and interviews to ascertain the opportunities for developing scientific literacy among participants. One critical factor that hindered learning was task selection by teachers, which emphasized generic scientific process skills over more important cognitive and epistemic learning goals. Teachers and students were also jointly engaged in forms of inquiry that underscored artifact completion over deeper conceptual and epistemic understanding of science. Our research surfaced two other confounding factors that undermined the curriculum; unanticipated teacher effects and the underestimation of the complexity of DBI and of inquiry science in general. Thus, even though motivated or experienced teachers can implement an inquiry science curriculum with good fidelity and enjoy school-wide support, these by themselves will not guarantee deep learning of scientific literacy in DBI. Recommendations are made for navigating the hands- and minds-on aspects of learning science that is an asset as well as inherent danger during DBI teaching. 相似文献

This study examined prospective elementary teachers' learning about scientific inquiry in the context of an innovative life science course. Research questions included: (1) What do prospective elementary teachers learn about scientific inquiry within the context of the course? and (2) In what ways do their experiences engaging in science investigations and teaching inquiry‐oriented science influence prospective elementary teachers' understanding of science and science learning and teaching? Eleven prospective elementary teachers participated in this qualitative, multi‐participant case study. Constant comparative analysis strategies attempted to build abstractions and explanations across participants around the constructs of the study. Findings suggest that engaging in scientific inquiry supported the development more appropriate understandings of science and scientific inquiry, and that prospective teachers became more accepting of approaches to teaching science that encourage children's questions about science phenomena. Implications include careful consideration of learning experiences crafted for prospective elementary teachers to support the development of robust subject matter knowledge. 相似文献

In most primary science classes, students are taught science inquiry skills by way of learning by doing. Research shows that explicit instruction may be more effective. The aim of this study was to investigate the effects of explicit instruction on the acquisition of inquiry skills. Participants included 705 Dutch fifth and sixth graders. Students in an explicit instruction condition received an eight-week intervention of explicit instruction on inquiry skills. In the lessons of the implicit condition, all aspects of explicit instruction were absent. Students in the baseline condition followed their regular science curriculum. In a quasi-experimental pre-test–post-test design, two paper-and-pencil tests and three performance assessments were used to examine the acquisition and transfer of inquiry skills. Additionally, questionnaires were used to measure metacognitive skills. The results of a multilevel analysis controlling for pre-tests, general cognitive ability, age, gender and grade level indicated that explicit instruction facilitates the acquisition of science inquiry skills. Specifically on the performance assessment with an unfamiliar topic, students in the explicit condition outperformed students of both the implicit and baseline condition. Therefore, this study provides a strong argument for including an explicit teaching method for developing inquiry skills in primary science education. 相似文献

ABSTRACTWhat are the current challenges and opportunities for bringing actor-network theory (ANT) into issues-based science education? This article discusses experiences gained from introducing an educational version of ANT deploying digital technology into an upper secondary school science class. This teaching innovation, called controversy mapping, has been pioneered in different contexts of higher education before being adapted to school education. Experimenting with controversy mapping in a Swedish science class raised both conceptual and practical issues. These centre on: (1) how ANT-inspired controversy mapping redesigns the citizenship training enacted by institutionalized approaches to issues-based education as socioscientific issues (SSI); (2) how controversy mapping reconfigures the interdisciplinarity of issues-based science education; and (3) how controversy mapping displaces scientific literacy and knowledge of the nature of science as guiding concerns for teaching in favour of new preoccupations with digital literacy and digital tools and methods as contemporary infrastructures of free and open inquiry. 相似文献

The need to equip science teachers with knowledge, skills, and habits of mind to face the challenges of teaching science through
inquiry informed this study, which analyzed the secondary science intern teachers’ beliefs about inquiry before, during, and
following a series of 2 consecutive science methods courses in an attempt to document the effect of such experiences on their
ability and willingness to infuse science inquiry in their science curricula. Nine science credentialing interns participated
in the study. Data was gathered from their written reflections and various assignments throughout the methods courses. Results
suggested that their beliefs changed significantly after the science methods courses. The implications of the study to secondary
science teacher educators and researchers were highlighted. 相似文献

Research on predictors of achievement in science is often targeted on more traditional content-based assessments and single student characteristics. At the same time, the development of skills in the field of scientific inquiry constitutes a focal point of interest for science education. Against this background, the purpose of this study was to investigate to which extent multiple student characteristics contribute to skills of scientific inquiry. Based on a theoretical framework describing nine epistemological acts, we constructed and administered a multiple-choice test that assesses these skills in lower and upper secondary school level (n?=?780). The test items contained problem-solving situations that occur during chemical investigations in school and had to be solved by choosing an appropriate inquiry procedure. We collected further data on 12 cognitive, motivational, and sociodemographic variables such as conceptual knowledge, enjoyment of chemistry, or language spoken at home. Plausible values were drawn to quantify students’ inquiry skills. The results show that students’ characteristics predict their inquiry skills to a large extent (55%), whereas 9 out of 12 variables contribute significantly on a multivariate level. The influence of sociodemographic traits such as gender or the social background becomes non-significant after controlling for cognitive and motivational variables. Furthermore, the performance advance of students from upper secondary school level can be explained by controlling for cognitive covariates. We discuss our findings with regard to curricular aspects and raise the question whether the inquiry skills can be considered as an autonomous trait in science education research. 相似文献

The University of Rochester's Graduate Experience in Science Education (GESE) course familiarizes biomedical science graduate students interested in pursuing academic career tracks with a fundamental understanding of some of the theory, principles, and concepts of science education. This one-semester elective course provides graduate students with practical teaching and communication skills to help them better relate science content to, and increase their confidence in, their own teaching abilities. The 2-h weekly sessions include an introduction to cognitive hierarchies, learning styles, and multiple intelligences; modeling and coaching some practical aspects of science education pedagogy; lesson-planning skills; an introduction to instructional methods such as case studies and problem-based learning; and use of computer-based instructional technologies. It is hoped that the early development of knowledge and skills about teaching and learning will encourage graduate students to continue their growth as educators throughout their careers. This article summarizes the GESE course and presents evidence on the effectiveness of this course in providing graduate students with information about teaching and learning that they will use throughout their careers. 相似文献

文章比较了中美两国教育文件中探究教学的概念或操作定义以及哲学基础,发现＂探究＂一词的意义相差甚远。认为旨在提高大众科学素养的探究教学不能强调于对科学探究过程技能的学习,应当侧重于对科学的理解。此为与新课程中提高科学素养目标相一致的探究教学要义。以达到用科学,而非做科学的目的。 相似文献

This paper provides a detailed analysis of the inclusion of aspects of nature of science (NOS) in the Next Generation Science Standards (NGSS). In this new standards document, NOS elements in eight categories are discussed in Appendix H along with illustrative statements (called exemplars). Many, but not all, of these exemplars are linked to the standards by their association with either the “practices of science” or “crosscutting concepts,” but curiously not with the recommendations for science content. The study investigated all aspects of NOS in NGSS including the accuracy and inclusion of the supporting exemplar statements and the relationship of NOS in NGSS to other aspects of NOS to support teaching and learning science. We found that while 92 % of these exemplars are acceptable, only 78 % of those written actually appear with the standards. “Science as a way of knowing” is a recommended NOS category in NGSS but is not included with the standards. Also, several other NOS elements fail to be included at all grade levels thus limiting their impact. Finally, NGSS fails to include or insufficiently emphasize several frequently recommended NOS elements such as creativity and subjectivity. The paper concludes with a list of concerns and solutions to the challenges of NOS in NGSS. 相似文献

The purpose of this study is to uncover and understand the factors that affect secondary science and mathematics teachers?? initial implementation of Technology-Enhanced Formative Assessment (TEFA), a pedagogy developed for teaching with classroom response system (CRS) technology. We sought to identify the most common and strongest factors, and to understand the general process of how teachers adopt TEFA. We identified ten main hindering factors reported by teachers, and found that time limitations and question development difficulties are reported as the most problematic. In this paper we provide five vignettes of teachers?? initial implementation experiences, illustrating different courses that TEFA adoption can follow. We classify our ten factors into four groups: contextual factors that directly hinder teachers?? attempts to implement TEFA (extrinsic type I); circumstances that affect teachers?? teaching in general (extrinsic type 0); gaps that teachers have in the knowledge and skills they need to adopt TEFA (intrinsic type I); and ways of being a teacher that describe teachers?? deeper perspectives and beliefs, which may be consonant or dissonant with TEFA (intrinsic type II). Finally, we identify four general categories that describe the teachers?? initial TEFA implementation. 相似文献

ABSTRACTMany science curricula and standards emphasise that students should learn both scientific knowledge and the skills associated with the construction of this knowledge. One way to achieve this goal is to use inquiry-learning activities that embed the use of science process skills. We investigated the influence of scientific reasoning skills (i.e. conceptual and procedural knowledge of the control-of-variables strategy) on students’ conceptual learning gains in physics during an inquiry-learning activity. Eighth graders (n?=?189) answered research questions about variables that influence the force of electromagnets and the brightness of light bulbs by designing, running, and interpreting experiments. We measured knowledge of electricity and electromagnets, scientific reasoning skills, and cognitive skills (analogical reasoning and reading ability). Using structural equation modelling we found no direct effects of cognitive skills on students’ content knowledge learning gains; however, there were direct effects of scientific reasoning skills on content knowledge learning gains. Our results show that cognitive skills are not sufficient; students require specific scientific reasoning skills to learn science content from inquiry activities. Furthermore, our findings illustrate that what students learn during guided inquiry activities becomes visible when we examine both the skills used during inquiry learning and the process of knowledge construction. The implications of these findings for science teaching and research are discussed. 相似文献

Science as inquiry and mathematics as problem solving are conjoined fraternal twins attached by their similarities but with distinct differences. Inquiry and problem solving are promoted in contemporary science and mathematics education reforms as a critical attribute of the nature of disciplines, teaching methods, and learning outcomes involving understandings, attitudes, and processes. The investigative and quantitative processes involved in scientific inquiry include seeking problems, identifying researchable questions, proposing hypotheses, designing fair tests, collecting and interpreting data as evidence for claims, constructing evidence-based arguments, and communicating knowledge claims. Within this empirical context, science and mathematics come together to solve problems with evidence, construct knowledge claims, communicate claims, and persuade others that the claims are valid and useful. This study examined the intersection of inquiry and problem solving and the use of mathematics in 26 extracurricular open science inquiries. The category and the appropriateness of the mathematical procedures revealed these students used measurement, numeracy skills of counting and calculation, and tables and graphs in their science inquiries. It was found that most measurements in the science inquiries were used appropriately, but there is room for improvement with other mathematical procedures that involve higher-level thinking skills, such as analyzing and calculating numerical data and interpreting graphs and tables. The findings imply that mathematics and science are connected in inquiry and should be extended to solve real-life problems and that instruction should emphasize comprehending and interpreting data. 相似文献

Although the effects of open inquiry vs. more didactic approaches have been studied extensively, the effects of different types of inquiry have not received as much attention. We examined the effects of guided vs. structured inquiry on secondary students' learning of science. Students from three schools in north-eastern Thailand participated (N?=?239, Grades 7 and 10). Two classes in each school were randomly assigned to either the guided or the structured-inquiry condition. Students had a total of 14–15 hours of instructions in each condition. The dependent measures were science content knowledge, science process skills, scientific attitudes, and self-perceived stress. In comparison to the structured-inquiry condition, students in the guided-inquiry condition showed greater improvement in both science content knowledge and science process skills. For scientific attitudes and stress, students in one school benefited from guided inquiry much more than they did from structured inquiry. Findings were explained in terms of differences in the degree to which students engaged effortfully with the teaching material. 相似文献

Learning science through the process of inquiry is advocated in curriculum documents across many jurisdictions. However, a number of studies suggest that teachers struggle to help students engage in inquiry practices. This is not surprising as many teachers of science have not engaged in scientific inquiry and possibly hold naïve ideas about what constitutes scientific inquiry. This study investigates teachers' self-reported approaches to teaching science through inquiry. Phenomenographic interviews undertaken with 20 elementary teachers revealed teachers identified six approaches to teaching for inquiry, clustered within three categories. These approaches were categorized as Free and Illustrated Inquiries as part of an Experience-centered category, Solution and Method Inquiries as part of a Problem-centered category, and Topic and Chaperoned Inquiries as part of a Question-centered category. This study contributes to our theoretical understanding of how teachers approach Inquiry Teaching and suggests fertile areas of future research into this valued and influential phenomenon broadly known as ‘Inquiry Teaching'. 相似文献

Just as scientific knowledge is constructed using distinct modes of inquiry (e.g. experimental or historical), arguments constructed during science instruction may vary depending on the mode of inquiry underlying the topic. The purpose of this study was to examine whether and how secondary science teachers construct scientific arguments during instruction differently for topics that rely on experimental or historical modes of inquiry. Four experienced high-school science teachers were observed daily during instructional units for both experimental and historical science topics. The main data sources include classroom observations and teacher interviews. The arguments were analyzed using Toulmin's argumentation pattern revealing specific patterns of arguments in teaching topics relying on these 2 modes of scientific inquiry. The teachers presented arguments to their students that were rather simple in structure but relatively authentic to the 2 different modes. The teachers used far more evidence in teaching topics based on historical inquiry than topics based on experimental inquiry. However, the differences were implicit in their teaching. Furthermore, their arguments did not portray the dynamic nature of science. Very few rebuttals or qualifiers were provided as the teachers were presenting their claims as if the data led straightforward to the claim. Implications for classroom practice and research are discussed. 相似文献
