Design activities, when embedded in an inquiry cycle and appropriately scaffolded and supplemented with reflection, can promote the development of the habits of mind (scientific abilities) that are an important part of scientific practice. Through the Investigative Science Learning Environment (ISLE), students construct physics knowledge by engaging in inquiry cycles that replicate the approach used by physicists to construct knowledge. A significant portion of student learning occurs in ISLE instructional labs where students design their own experiments. The labs provide an environment for cognitive apprenticeship enhanced by formative assessment. As a result, students develop interpretive knowing that helps them approach new problems as scientists. This article describes a classroom study in which the students in the ISLE design lab performed equally well on traditional exams as ISLE students who did not engage in design activities. However, the design group significantly outperformed the non-design group while working on novel experimental tasks (in physics and biology), demonstrating the application of scientific abilities to an inquiry task in a novel content domain. This research shows that a learning environment that integrates cognitive apprenticeship and formative assessment in a series of conceptual design tasks provides a rich context for helping students build scientific habits of mind.  相似文献

The use of inquiry‐based laboratory in college science classes is on the rise. This study investigated how five nonmajor biology students learned from an inquiry‐based laboratory experience. Using interpretive data analysis, the five students' conceptual ecologies, learning beliefs, and science epistemologies were explored. Findings indicated that students with constructivist learning beliefs tended to add more meaningful conceptual understandings during inquiry labs than students with positivist learning beliefs. All students improved their understanding of experiment in biology. Implications for the teaching of biology labs are discussed. © 2003 Wiley Periodicals, Inc.

We reviewed eight studies that described learning differences between students with learning disabilities (LD) and students with mild mental retardation (MMR). A total of 639 students, 6–20 years old, participated in these studies. Study authors examined students' inductive reasoning and their performance during guided inquiry and more lengthy interventions in reading and math. Students with LD and students with MMR were assessed in terms of learning ease, pre‐ to posttreatment gains, and the maintenance, transfer, and application of knowledge acquisition. Students with LD statistically significantly outperformed students with MMR on both inductive reasoning and guided inquiry tasks. They made reliably larger gains following interventions in reading and math. Across all learning tasks and contexts, students with LD displayed greater consistency transferring and applying conceptual knowledge to new tasks. Regarding maintenance, results were mixed. Implications for categorical instruction are discussed.  相似文献

This article describes a graduate course on alternative assessment in which the instructional intervention was designed in accordance with constructivist principles. The research examines the effect of this intervention on the learning and knowledge building processes and the subsequent quality of knowledge, as evidenced in students’ learning journals. The aims of the intervention were: (a) to introduce the students to a culture which facilitates the application of alternative assessment; (b) to familiarise the students with alternative assessment instruments through their own personal experience; and (c) to enhance reflection on assessment topics so as to contribute to mindful assessment practice. The intervention included a variety of teaching methods centred on activities that involve a multidirectional dialogue amongst the course participants. The 25 participants formed a heterogeneous group as far as teaching experience, class teaching level, types of school, and reasons for joining the course. To examine the effect of the intervention, the learning journals were analysed qualitatively. As a result of the analysis two dimensions were identified: reflection and learning outcomes. The first included two categories: metacognition and reflectivity, whereas the second included three categories: personalisation of knowledge, its development and its quality. The learning journals were scored with respect to these categories and the score distributions were examined. The findings pointed to conceptual development and change occurring to a large extent in about half of the students. The article concludes with discussion of the factors which seem to facilitate the construction of personal knowledge.  相似文献

This paper reports on the reality of classroom‐based inquiry learning in science, from the perspectives of high school students and their teachers, under a national curriculum attempting to encourage authentic scientific inquiry (as practiced by scientists). A multiple case study approach was taken, utilising qualitative research methods of unobtrusive observation, semi‐structured interviews and document analysis. The findings showed purposeful and focused learning occurring, but students were acquiring a narrow view of scientific inquiry where the thinking was characteristically rote and low‐level. The nature of this learning was strongly influenced by curriculum decisions made by classroom teachers and science departments in response to the assessment requirements of a high stakes national qualification. As a consequence of these decisions, students experienced structured teaching programmes in which they were exposed to programme content that limited the range of methods that scientists use to fair testing and to pedagogies that were substantially didactic in nature. In addition, the use of planning templates and exemplar assessment schedules tended to reduce student learning about experimental design to an exercise in “following the rules” as they engaged in closed rather than open investigations. Thus, the resulting student learning was mechanistic and superficial rather than creative and critical, counter to the aims of the national curriculum policy that is intent on promoting students’ knowledge and capabilities in authentic scientific inquiry.  相似文献

The philosophical foundation for teaching art criticism in schools has been dominated by formalist and expressionist aesthetics, while from a practical point of view it has been influenced by art criticism models that emphasise observation and linguistic practices. Instead of asking students to observe an artwork and make verbal or written statements, George Geahigan proposed an inquiry‐based art criticism learning model that engages students in personal response, research, and aesthetic concept and perceptual skill acquisition activities. Using inquiry‐based art criticism as a foundation for curriculum development and connecting the model to authentic situations in schools, the present study investigated the effectiveness of the model on student learning. Fifteen secondary school teachers were invited to participate. Eight teachers taught the experimental group (n=85) with inquiry‐based curriculum plans and the other seven teachers taught the control group (n=82) with their own school curriculum plans. Students of both groups were asked to write an art criticism essay before and after the implementation of the curriculum plans. The results demonstrated that the overall improvement of the experimental group after one academic year was significantly greater than that of the control group. This article reports on the theoretical framework, methodology and results of the study. It was found that the inquiry‐based approach was a successful strategy in improving students’ skills in analysing, judging and using aesthetic and contextual knowledge in art criticism writing. The discussion focuses on the improvements that were made in the art criticism essays of the experimental group.  相似文献

ABSTRACT Outcomes and mediators of differences in online and traditional course delivery were tested with a sample of 112 graduate students who completed an introductory course in training and development. Specifically, the individual learner characteristics of self‐efficacy, motivation, goal orientation, and meta‐cognition and their effects on success through online delivery were examined. The study also addressed three outcomes: trainees' reactions to that program, their learning, and subsequent planned changes in job behavior. The findings indicate that online learners have significantly more positive reaction levels of enjoyment and utility and significantly stronger intent to transfer their learning. Online students find the coursework more difficult, but there was no significant difference in learning based on delivery mode. Implications for both managers and educators involved in online learning are discussed.  相似文献

A new learning unit in chemistry, Case-based Computerized Laboratories (CCL) and Computerized Molecular Modeling (CMM) was developed at the Technion. The CCL and CMM curriculum integrates computerized desktop experiments and molecular modeling with an emphasis on scientific inquiry and case studies. Our research aimed at investigating the effect of the CCL and CMM learning environment on students’ higher-order thinking skills of question posing, inquiry, and modeling. The experimental group included 614 honors 12th grade chemistry students from high schools in Israel who studied according to this learning unit. The comparison group consisted of 155 12th grade chemistry honors students who studied other chemistry programs. Pre- and post-tests questionnaires were used to assess students’ higher-order thinking skills. Students’ responses were analyzed using content analysis rubrics and their statistical analysis. Our findings indicated that the scores of the experimental group students improved significantly in question posing, inquiry and modeling skills from the pre-test to the post-test. The net gain scores of the experimental group students were significantly higher than those of their comparison peers in all three examined skills. In modeling skills, experimental group students significantly improved their achievements in making the transfer from 3D models to structural formulae, but only about half of them were able to transfer from formulae to 3D models. By presenting a case-based chemistry assessment tool and content analysis of students’ responses in this paper, we enable teachers and educators to analyze their students’ higher-order thinking skills both qualitatively and quantitatively.  相似文献

Although researchers call for inquiry learning in science, science assessments rarely capture the impact of inquiry instruction. This paper reports on the development and validation of assessments designed to measure middle-school students’ progress in gaining integrated understanding of energy while studying an inquiry-oriented curriculum. The assessment development was guided by the knowledge integration framework. Over 2 years of implementation, more than 4,000 students from 4 schools participated in the study, including a cross-sectional and a longitudinal cohort. Results from item response modeling analyses revealed that: (a) the assessments demonstrated satisfactory psychometric properties in terms of reliability and validity; (b) both the cross-sectional and longitudinal cohorts made progress on integrating their understanding energy concepts; and (c) among many factors (e.g. gender, grade, school, and home language) associated with students’ science performance, unit implementation was the strongest predictor.  相似文献

Individual learning differences under competitive and co‐operative methods of instruction were investigated. It was hypothesised that: (a) students would learn more when the method was matched to the student's preference and that (b) the co‐operative (and tutorial) methods would promote more favourable attitudes toward peer students. One hundred and thirty‐two female students participated in the experiment. In the first part of the experiment they were asked to state their preferences and in the second part, half of the students received their preferred method of instruction. Both hypotheses were confirmed. In addition, it was found that students who preferred competition had better initial knowledge of the material, learned more during the learning experience and held somewhat less favourable attitudes toward their peers. The analysis of the results suggests that the interaction between goal, individual, subject‐matter and learning methods needs to be taken into account when determining an optimal method of instruction.  相似文献

We present an inquiry‐based, aquatic science professional development (PD) for upper‐elementary, middle, and high school teachers and examine changes in student outcomes in light of participating teachers’ characteristics and the grade band of the students. Our study lends support to the assertion that inquiry‐ and content‐focused PD, paired with classroom implementation, can effectively improve student learning. Our findings indicate that students improved in their nature of science (NOS) and aquatic science content knowledge and that these changes depended in some ways on the participating teachers’ characteristics and adherence to the program. The students’ improvements were amplified when their teachers adhered more closely to the PD activities during their classroom implementation. The teachers’ previous science PD experience and pre‐PD understanding of inquiry‐based teaching also explained some of the variability in student growth. In both NOS and content, students of teachers with less prior science‐PD experience benefited more. Grade band also explained variation in student outcomes through interactions with teacher‐characteristic variables. In high school, students of teachers with lower pre‐PD inquiry knowledge appeared to learn more about NOS. Our results suggest that inquiry and content training through PD may minimize disparities in teaching due to inexperience and lack of expertise. Our study also demonstrates the value of PD that teaches a flexible approach to inquiry and focuses on underrepresented, interdisciplinary content areas, like aquatic science. © 2017 Wiley Periodicals, Inc.

Experiments are essential for both doing science and learning science. The aim of the German youth science fair, Jugend forscht, is to encourage scientific thinking and inquiry methods such as experimentation. Based on 57 interviews with participants of the competition, this study summarises students’ conceptions and steps of learning about experimentation, taking into account age disparities. Five distinct subdomains of learning were identified in which learning processes may occur. These subdomains are procedure, purpose, material, control, and time. The three separate age groups used slightly different concepts but all the participants took the same or very similar steps of learning independent of their age. Two main reasons for conceptual developments could be detected: Firstly, the participating students had the opportunity to work using methodology similar to the commonly accepted scientific path of knowledge. Secondly, due to communication processes during the competition, a purposive reflection of their own project was promoted. With respect to different educational levels, experimentation proves to be a complex scientific framework that will be learnt step by step throughout students’ education. We therefore argue for a stronger anchoring of research experiments embedded in open or authentic inquiry to be included in science lessons at school.  相似文献

Although science has received much attention as a political and educational initiative, students with learning disabilities (LD) perform significantly lower than their nondisabled peers. This meta‐analysis evaluates the effectiveness of instructional strategies in science for students with LD. Twelve studies were examined, summarized, and grouped according to the type of strategy implemented. Effect sizes (ES) were calculated for each study. Across all studies, a mean ES of .78 was obtained, indicating a moderate positive effect on students with LD science achievement. Findings also align with past reviews of inquiry‐based instruction for students with special needs, indicating that students with LD need structure within an inquiry science approach in order to be successful. Additionally, results suggest that mnemonic instruction is highly effective at increasing learning disabled students' acquisition and retention of science facts.  相似文献

Six remedial reading teachers in a large, rural school district participated in a form of professional development called Teaching as Intentional Learning, based on an inquiry process. Their topic of inquiry was formative assessment. Professional development comprised both direct instruction and inquiry learning in teachers’ own classrooms. This study describes the strategies they experimented with, their professional growth in formative assessment, and effects on students. All six teachers showed important professional growth, as indicated by their own reflections and also by their supervisor’s observations. In First Grade, at‐risk students assigned to these project teachers had increased reading readiness scores on one measure (DIBELS PSF) compared with at‐risk students assigned to non‐project teachers.  相似文献

System thinking skills at the elementary school level   总被引:1,自引:0,他引:1  
This study deals with the development of system thinking skills at the elementary school level. It addresses the question of whether elementary school students can deal with complex systems. The sample included 40 4th grade students from one school in a small town in Israel. The students studied an inquiry‐based earth systems curriculum that focuses on the hydro‐cycle. The program involved lab simulations and experiments, direct interaction with components and processes of the water cycle in the outdoor learning environment and knowledge integration activities. Despite the students' minimal initial system thinking abilities, most of them made significant progress with their ability to analyze the hydrological earth system to its components and processes. As a result, they recognized interconnections between components of a system. Some of the students reached higher system thinking abilities, such as identifying interrelationships among several earth systems and identifying hidden parts of the hydrological system. The direct contact with real phenomena and processes in small scale scenarios enabled these students to create a concrete local water cycle, which could later be expanded into large scale abstract global cycles. The incorporation of outdoor inquiry‐based learning with lab inquiry‐based activities and knowledge integration assignments contributed to the 4th grade students' capacity to develop basic system thinking abilities at their young age. This suggests that although system thinking is regarded as a high order thinking skill, it can be developed to a certain extent in elementary school. With a proper long‐term curriculum, these abilities can serve as the basis for the development of higher stages of system thinking at the junior–high/middle school level. © 2009 Wiley Periodicals, Inc.

Designing and conducting sound and informative experiments is an important aspect of inquiry learning. Students, however, often design experiments that do not allow them to reach conclusions. Considering the difficulties students experience with the process of designing experiments, additional guidance in the form of an Experiment Design Tool (EDT) was developed, together with reflection questions. In this study, 147 pre-university students worked in an online inquiry learning environment on buoyancy and Archimedes’ principle. Students were randomly assigned to one of three conditions, each of which contained a different version of the EDT. Since students’ prior knowledge has been found to influence the amount and type of guidance they need, the versions of the tool differed with respect to the level of guidance provided. A pre- and post-test were administered to assess students’ conceptual knowledge. No overall differences between conditions were found. In a subsequent analysis, students were classified as either low, low-intermediate-, high-intermediate, or high prior knowledge students. For Archimedes’ principle we found that low-intermediate prior knowledge students gained significantly more conceptual knowledge than low prior knowledge students in the fully guided condition. It is hypothesised that students need at least some prior knowledge in order to fully benefit from the guidance offered.  相似文献

This study investigated the effects of students’ prior science knowledge and online learning approaches (social and individual) on their learning with regard to three topics: science concepts, inquiry, and argumentation. Two science teachers and 118 students from 4 eighth-grade science classes were invited to participate in this research. Students in each class were divided into three groups according to their level of prior science knowledge; they then took either our social- or individual-based online science learning program. The results show that students in the social online argumentation group performed better in argumentation and online argumentation learning. Qualitative analysis indicated that the students’ social interactions benefited the co-construction of sound arguments and the accurate understanding of science concepts. In constructing arguments, students in the individual online argumentation group were limited to knowledge recall and self-reflection. High prior-knowledge students significantly outperformed low prior-knowledge students in all three aspects of science learning. However, the difference in inquiry and argumentation performance between low and high prior-knowledge students decreased with the progression of online learning topics.  相似文献

This article examines the strategies that can be used to enhance students' understanding of how subjects link together and whether cross‐curricular approaches, through a gallery project, have any real impact on students' understanding of the links between subjects. A substantial part of this article, however, describes the methodological aspect of the project. A phenomenological case study approach was used in order to engage fully with individual students' learning experiences. It was found that the students who were involved directly with the study felt that the links between subjects had more relevance to their learning when the teacher made such links explicit. They were unaware of the relevance of many cross‐curricular links made in lessons, but the study indicated that cross‐curricular learning can enable students to transfer skills and knowledge in order to understand concepts more fully.  相似文献

This article, written primarily from the perspective of employment‐related learning, seeks to challenge several common assumptions about the Learning Society: that learning depends on the provision of education and training, that provision is based on sufficient attention to wants and valid assessment of needs; that provision is appropriately distributed between different types of knowledge; that transfer of knowledge is an event rather than a process; that expertise can be represented in terms of propositional knowledge alone; that current job competence is an adequate basis for assessing individual capability or organizational need. An alternative conceptual framework is proposed which takes account of recent research into the complex, multifaceted nature of expertise; reframes the concept of transfer as a learning process which requires dedicated time and effort; treats individual learning for employment in terms of comprising capability, competence and understanding; clarifies the tension between short‐term efficiency and long‐term adaptability in people and organizations; and provides operational definitions for studying learning groups, learning organizations and a learning society.  相似文献
