ABSTRACT

Many 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

Problem-solving skills and understanding of domain, knowledge (e.g., fighting misconceptions) are important goals in both secondary and tertiary science education. A prototype of an instructional task is presented which aims at improved problem-solving skills based on understanding of domain knowledge. In this task, comparing carefully selected solved problems by groups of students is utilised as a learning activity for the acquisition of adequate problem schemata. The task is designed as a part of the so-called UBP-program (UBP=Understanding Based Problem solving) currently being developed, for education in science. The result of an evaluative study for the field of mechanics is presented. The UBP-task appears apt to improve problem-solving skills at a less advanced level of physics education (e.g., 10th grade), especially for students normally performing poorly—who are often girls.  相似文献

ABSTRACT: Problem-based learning (PBL) activities incorporated into an introductory food science course can aid in student understanding of basic food science principles while developing students' problem-solving and critical thinking skills. This article describes one example of how problem-based learning was introduced into an introductory food science course designed for food and nutrition majors. Included are the problems that were developed for the course and the observed outcomes of the problem-based learning activities. Integrated problem-based learning aided students in developing communication, problem-solving, self-directed learning, and other desired skills and demonstrates the potential to be an enjoyable and challenging classroom experience for both students and teachers. However, poor problem design, such as introducing numerous problems for one subject area, may generate unanticipated quick answer approaches to solving problems.  相似文献

The evolving technological landscape in the digital era has a crucial influence on lifelong learning and the demand for problem-solving skills. In this paper, we identify associations between formal, non-formal and informal learning with sufficient problem-solving skills in technology-rich environments (TRE). We focus on adults' problem-solving skills in TRE as a novel approach to investigate formal, non-formal and informal learning based on data from the Programme for the International Assessment of Adult Competencies. This programme measured 16–64-year-old adults' proficiency in problem-solving skills in TRE. The total sample size was 61 654 individuals from 13 European countries. Our results clearly indicate that the skill levels of more than 50% of adults aged 16–64 years old seem to be insufficient to cope effectively in TRE. The findings suggest that the learning ecologies of adults are a combination of formal, non-formal and informal learning activities. The overall level of problem-solving skills in TRE was higher among individuals who indicated that they have participated either formal or non-formal learning activities, compared to those who have not. However, interestingly, the association between formal learning and problem-solving skills in TRE was not major. Instead, our results clearly indicate that informal learning seems to be highly associated with sufficient problem-solving skills in TRE. In practice, we outline those formal, non-formal and informal learning activities that adults perform when applying the skills in TRE. By recognising these activities undertaken by sufficient problem solvers, we can promote lifelong learning skills. Our findings can also be used as a starting point for future studies on lifelong learning.  相似文献

Learning in today's classrooms can be disconnected from students' real world experiences. Providing students the opportunity to address real‐world problems may provide avenues for students to engage in their communities while developing academic skills and knowledge. Additionally, for students whose interests are piqued by the nature of their community's problems, these activities have the potential to offer students meaningful, motivating work in a supportive environment. This article explores how providing students with interest‐based service‐learning opportunities may help them develop and demonstrate gifted behaviors. In addition, methods for integrating student interests and service‐learning projects are presented. © 2012 Wiley Periodicals, Inc.  相似文献

Active learning methods can be appropriate in engineering, as their methodology promotes meta-cognition, independent learning and problem-solving skills. Problem-based learning is the educational process by which problem-solving activities and instructor's guidance facilitate learning. Its key characteristic involves posing a ‘concrete problem’ to initiate the learning process, generally implemented by small groups of students. Many universities have developed and used active methodologies successfully in the teaching–learning process. During the past few years, the University of the Basque Country has promoted the use of active methodologies through several teacher training programmes. In this paper, we describe and analyse the results of the educational experience using the problem-based learning (PBL) method in a physics course for undergraduates enrolled in the technical telecommunications engineering degree programme. From an instructors’ perspective, PBL strengths include better student attitude in class and increased instructor–student and student–student interactions. The students emphasised developing teamwork and communication skills in a good learning atmosphere as positive aspects.  相似文献

Hypermedia learning environments (HLE) unevenly present new challenges and opportunities to learning processes and outcomes depending on learner characteristics and instructional supports. In this experimental study, we examined how one such HLE—MetaTutor, an intelligent, multi-agent tutoring system designed to scaffold cognitive and metacognitive self-regulated learning (SRL) processes—interacts with learner’s prior domain knowledge to affect their note-taking activities and subsequent learning outcomes. Sixty (N = 60) college students studied with MetaTutor for 120 min and took notes on hypermedia content of the human circulatory system. Log-files and screen recordings of learner-system interactions were used to analyze notes for several quantitative and qualitative variables. Results show that most note-taking was a verbatim copy of instructional content, which negatively related to the post-test measure of learning. There was an interaction between prior knowledge and pedagogical agent scaffolding, such that low prior knowledge students took a greater quantity of notes compared to their high prior knowledge counterparts, but only in the absence of MetaTutor SRL scaffolding; when agent SRL scaffolding was present, the note-taking activities of low prior knowledge students were statistically equivalent to the number of notes taken by their high prior knowledge counterparts. Theoretical and instructional design implications are discussed.  相似文献

Active‐learning labs for two topics in high school biology were developed through the collaboration of high school teachers and university faculty and staff and were administered to 408 high school students in six classrooms. The content of instruction and testing was guided by State of Texas science objectives. Detailed teacher records describing daily classroom activities were used to operationalize two types of instruction: active learning, which used the labs; and traditional, which used the teaching resources ordinarily available to the teacher. Teacher records indicated that they used less independent work and fewer worksheets, and more collaborative and lab‐based activities, with active‐learning labs compared to traditional instruction. In‐class test data show that students gained significantly more content knowledge and knowledge of process skills using the labs compared to traditional instruction. Questionnaire data revealed that students perceived greater learning gains after completing the labs compared to covering the same content through traditional methods. An independent questionnaire administered to a larger sample of teachers who used the lab‐based curriculum indicated that they perceived changing their behaviors as intended by the student‐centered principles of the labs. The major implication of this study is that active‐learning–based laboratory units designed and developed collaboratively by high school teachers and university faculty, and then used by high school teachers in their classrooms, can lead to increased use of student‐centered instructional practices as well as enhanced content knowledge and process learning for students. © 2007 Wiley Periodicals, Inc.

As part of a project to identify opportunities for reasoning that occur in good but typical science classrooms, this study focuses on how sixth graders reason about the goals and strategies of experimentation and laboratory activities in school. Collaborating with teachers, we explore whether reasoning can be deepened by developing instruction that capitalizes more effectively on the classroom opportunities that arise for fostering complex thinking and understanding. The design of the study includes (a) a baseline interview probing students' understanding of experimentation in the context of a standard, 40-min "hands-on" activity that is part of the standard sixth-grade curriculum; (b) a 3-week teaching study, in which five teachers, informed by the cognitive science research concerning the development of scientific reasoning, designed and taught a special experimentation unit in their classrooms; and (c) a series of follow-up interviews, in which students' understanding of experimentation was reexamined. The findings from the two learning contexts-one more supportive of student reasoning than the other-inform us about the kinds of reasoning that are developing in middle-school students and the forms of instruction best suited to exercising those developing skills.  相似文献

The purpose of this cross-case analysis is to illustrate how and why literacy was incorporated into science teaching and learning in three secondary classrooms. Research questions guiding the analysis include: (a) How were literacy events shaped by the teachers' philosophies about teaching science content and teaching students? and (b) How was literacy (reading, writing, and oral language) structured by the teachers and manifested in science lessons? The methodology of ethnography and the theoretical framework of symbolic interactionism were employed in the three studies on which the cross-case analysis was based. The researchers assumed the role of participant observers, collecting data over the period of 1 year in each of the three classrooms. Data, in the form of fieldnotes, interviews, and artifacts, were collected. In each study, data were analyzed using the constant comparative method (Glaser & Strauss, 1967) to determine patterns in the teachers' beliefs about learning and how these influenced their choice of literacy activities. The cross-case analysis was conducted to determine patterns across the three teachers and their classrooms. The findings from this analysis are used to compare how the teachers' philosophies of teaching science and their beliefs about how students learn influenced their use of literacy practices during lessons. Specifically, each teacher's use of literacy activities varied based on his or her beliefs about teaching science concepts. Furthermore, reading, writing, and oral language were important vehicles to learning science concepts within daily classroom activities in the three classrooms.  相似文献

In this paper we reflect on the article, Science education in a bilingual class: problematising a translational practice, by Zeynep Ünsal, Britt Jakobson, Bengt-Olav Molander and Per-Olaf Wickman (Cult Stud Sci Educ, doi: 10.1007/s11422-016-9747-3). In their article, the authors present the results of a classroom research project by responding to one main question: How is continuity between everyday language and the language of science construed in a bilingual science classroom where the teacher and the students do not speak the same minority language? Specifically, Ünsal et al. examine how bilingual students construe relations between everyday language and the language of science in a class taught in Swedish, in which all students also spoke Turkish, whereas the teacher also spoke Bosnian, both being minority languages in the context of Swedish schools. In this forum, we briefly discuss why close attention to bilingual dynamics emerging in classrooms such as those highlighted by Ünsal et al. matters for science education. We continue by discussing changing ontologies in relation to linguistic diversity and education more generally. Recent research in bilingual immersion classroom settings in so-called “content” subjects such as Content and Language Integrated Learning, is then introduced, as we believe this research offers some significant insights in terms of how bilingualism contributes to knowledge building in subjects such as science. Finally, we offer some reflections in relation to the classroom interactional competence needed by teachers in linguistically diverse classrooms. In this way, we aim to further the discussion initiated by Ünsal et al. and to offer possible frameworks for future research on bilingualism in science education. In their article, Ünsal et al. conclude the analysis of the classroom data by arguing in favor of a translanguaging pedagogy, an approach to teaching and learning in which students’ whole language repertoires are used as valuable resources for constructing meaning and for developing academic competences in the language of instruction. This is a conclusion that we support wholeheartedly and an educational practice that we hope to promote with this forum discussion.  相似文献

Recognising critical reasoning and problem-solving as one of the key skills for twenty-first century citizenship, various types of problem contexts have been practiced in science classrooms to enhance students’ understandings and use of evidence-based thinking and justification. Good problems need to allow students to adapt and evaluate the effectiveness of their knowledge, reasoning and problem-solving strategies. When students are engaged in complex and open-ended problem tasks, it is assumed their reasoning and problem-solving paths become complex with creativity and evidence in order to justify their conclusion and solutions. This study investigated the levels of reasoning evident in student discourse when engaging in different types of problem-solving tasks and the role of teacher interactions on students’ reasoning. Fifteen students and a classroom teacher in a Grade 5–6 classroom participated in this study. Through case analyses, the study findings suggest that (a) there was no clear co-relation between certain structures of problem tasks and the level of reasoning in students’ problem-solving discourse, (b) students exhibited more data-based reasoning than evidence-based and rule-based justification in experiment-based problem-solving tasks, and (c) teacher intervention supported higher levels of student reasoning. Pedagogical reflections on the difficulties of constructing effective problem-solving tasks and the need for developing teacher scaffolding strategies are discussed.  相似文献

This is an editorial report on the outcomes of an international conference sponsored by a grant from the National Science Foundation (NSF) (REESE-1205273) to the School of Education at Boston University and the Center for Philosophy and History of Science at Boston University for a conference titled: How Can the History and Philosophy of Science Contribute to Contemporary US Science Teaching? The presentations of the conference speakers and the reports of the working groups are reviewed. Multiple themes emerged for K-16 education from the perspective of the history and philosophy of science. Key ones were that: students need to understand that central to science is argumentation, criticism, and analysis; students should be educated to appreciate science as part of our culture; students should be educated to be science literate; what is meant by the nature of science as discussed in much of the science education literature must be broadened to accommodate a science literacy that includes preparation for socioscientific issues; teaching for science literacy requires the development of new assessment tools; and, it is difficult to change what science teachers do in their classrooms. The principal conclusions drawn by the editors are that: to prepare students to be citizens in a participatory democracy, science education must be embedded in a liberal arts education; science teachers alone cannot be expected to prepare students to be scientifically literate; and, to educate students for scientific literacy will require a new curriculum that is coordinated across the humanities, history/social studies, and science classrooms.  相似文献

Metacognition and self-regulation are important for developing effective learning in the classroom and beyond, but novice learners often lack effective metacognitive and self-regulatory skills. However, researchers have demonstrated that metacognitive processes can be developed through practice and appropriate scaffolding. Betty’s Brain, an open-ended computer-based learning environment, helps students practice their cognitive skills and develop related metacognitive strategies as they learn science topics. In this paper, we analyze students’ activity sequences in a study that compared different categories of adaptive scaffolding in Betty’s Brain. The analysis techniques for measuring students’ cognitive and metacognitive processes extend our previous work on using sequence mining methods to discover students’ frequently-used behavior patterns by (i) developing a systematic approach for interpreting derived behavior patterns using a cognitive/metacognitive task model and (ii) analyzing the evolution of students’ frequent behavior patterns over time. Our results show that it is possible to identify students’ learning behaviors and analyze their evolution as they work in the Betty’s Brain environment. Further, the results illustrate that changes in student behavior were generally consistent with the scaffolding provided, suggesting that these metacognitive strategies can be taught to middle school students in computer-based learning environments.  相似文献

During early childhood, children start developing their cognitive, social, emotional, and behavioural skills, laying the foundation for life-long learning. Cognitive skills are usually taught in traditional classrooms through the use of textbooks and worksheets. The learning content in these textbooks and worksheets is static pre-authored content that is repeatedly used for teaching and learning. This repetition jeopardises the child's learning of individualised and cognitive skills. Preschool cognitive skills learning content comprises facts of everyday life. Similarly, the Semantic Web attempts to model these facts through ontologies. From this, a relationship appears between preschool cognitive skills learning content and the ontologies. The present work focuses on the stated problem and presents the theoretical and development details of a child-friendly tutoring application that dynamically generates cognitive skills learning content using ontologies as domain knowledge. The proposed application was evaluated in a preschool environment for its learning effectiveness and the correctness of the generated content. Three groups of preschool children participated in the study for preschool cognitive skills learning through the use of the proposed application. The first group learned the cognitive skills through the traditional method with textbooks and the teacher's teaching. The second group learned the skills through the proposed application at school in classroom sessions. The third group experienced the proposed application both at school and at home, along with regular classroom sessions. The results show significant gains by the third group over the other two groups, and hence support the use of the proposed application in practice. However, the enhanced learning by the third group disappears if the additional application usage time is removed. Moreover, the results of the expert evaluation show that a great deal of the learning content was correctly generated, thus justifying the true modelling of the domain ontology.  相似文献

The attributes of self-direction in learning are becoming increasingly important as the need for lifelong learning grows in strength. Educators are challenged to assist in the development of self-directed learning skills and to encourage learners to more freely use self-direction in their learning activities. Unfortunately, there are few validated procedures for identifying the self-directed learners. Guglielmino's Self-Directed Learning Readiness Scale is one of the few instruments identified in the literature for the purpose of measuring self-direction in learning. Even though the scale has been widely used, additional validation is needed. This study was designed to use a multitrait-multimethod procedure for determining the validity of the SDLRS. The sample included 136 college students from two different colleges: 63 black students, 70 white students and 3 students of other nationalities (other than USA). Thirty-seven specific hypotheses were tested. Findings concerning selected hypotheses are discussed. Three general conclusions concerning the validity of the SDLRS are as follows: (1) The findings are supportive of the validity of the SDLRS; (2) Significant differences were noted in faculty ratings according to racial composition and student scores on the SDLRS; (3) Significant associations exist between the SDLRS scores and variables such as age, educational level and ARS (agreement response set).  相似文献

Research on the utilization of the Web for complex fine motor skill learning that involves whole body movements is still scarce. The aim of this study was to evaluate the impact of the introduction of a multimedia web-based learning environment, which was targeted at a rhythmic gymnastics routine consisting of eight fine motor skills, into an undergraduate course in a physical education department, as a complementary tool to campus-based instruction. The impact was evaluated in terms of: acquisition of knowledge regarding the routine skills by students, improvement of students’ ability to execute the routine, and students’ responses to the environment. The study followed a pretest/posttest experimental design and involved 76 students randomly split into two groups: The Multimedia Web-based Learning Group (MWLG) students (N?=?38), who attended campus-based instruction on the routine and also used the environment in their own space and time, and the Traditional On-site Instruction Group (TOIG) students (N?=?38), who only attended campus-based instruction. The research data were gathered through student questionnaires and ratings of students’ performances. It was found that the use of the environment as a supplement to campus-based instruction increased the effectiveness of this instruction as regards the cognitive component of motor skill learning (i.e. acquisition of knowledge regarding the routine skills) and was well-accepted by the students, although it did not have any significant contribution to the physical component of motor skill learning (i.e. performance of the routine skills). These findings partially support the future wider adoption of multimedia web-based learning environments within physical education and other academic disciplines that involve complex fine motor skill learning. Relevant implications are discussed.  相似文献

Within the domain of geometry, proof and proof development continues to be a problematic area for students. Battista (2007) suggested that the investigation of knowledge components that students bring to understanding and constructing geometry proofs could provide important insights into the above issue. This issue also features prominently in the deliberations of the 2009 International Commission on Mathematics Instruction Study on the learning and teaching of proofs in mathematics, in general, and geometry, in particular. In the study reported here, we consider knowledge use by a cohort of 166 Sri Lankan students during the construction of geometry proofs. Three knowledge components were hypothesised to influence the students’ attempts at proof development: geometry content knowledge, general problem-solving skills and geometry reasoning skills. Regression analyses supported our conjecture that all 3 knowledge components played important functions in developing proofs. We suggest that whilst students have to acquire a robust body of geometric content knowledge, the activation and the utilisation of this knowledge during the construction of proof need to be guided by general problem-solving and reasoning skills.  相似文献

The purpose of this study was to examine the effectiveness of traditional versus guided inquiry (with problem-solving process and cognitive function training) on high school chemistry knowledge, science process skills, scientific attitudes, and problem-solving competency. Two classes of students were recruited from three classes of Grade 11 students at one school in North-eastern Thailand. Using a split-plot design, students were assigned to an experimental (N = 34) and a control group (N = 31), and were administered (a) learning achievement tests (chemistry knowledge, science process skills, and scientific attitude), (b) a problem-solving competency test, and c) tests of cognitive functioning. The findings showed that students’ learning achievement and problem-solving competency in the guided inquiry group were significantly higher than in the traditional group. The effect of the new teaching method does not seem to stem solely from improvement in cognitive functioning. We attributed the improvement to greater flexibility in the amount of information provided by the teachers, more effortful processing by the students, and greater collaboration amongst the students.  相似文献

To learn content knowledge in science, technology, engineering, and math domains, students need to make connections among visual representations. This article considers two kinds of connection-making skills: (1) sense-making skills that allow students to verbally explain mappings among representations and (2) perceptual fluency in connection making that allows students to fast and effortlessly use perceptual features to make connections among representations. These different connection-making skills are acquired via different types of learning processes. Therefore, they require different types of instructional support: sense-making activities and fluency-building activities. Because separate lines of research have focused either on sense-making skills or on perceptual fluency, we know little about how these connection-making skills interact when students learn domain knowledge. This article describes two experiments that address this question in the context of undergraduate chemistry learning. In Experiment 1, 95 students were randomly assigned to four conditions that varied whether or not students received sense-making activities and fluency-building activities. In Experiment 2, 101 students were randomly assigned to five conditions that varied whether or not and in which sequence students received sense-making and fluency-building activities. Results show advantages for sense-making and fluency-building activities compared to the control condition only for students with high prior chemistry knowledge. These findings provide new insights into potential boundary conditions for the effectiveness of different types of instructional activities that support students in making connections among multiple visual representations.  相似文献
