This study investigated the effects of different teaching and learning methods for statistics for 2 levels of prior knowledge on cognitive load, propositional knowledge, and conceptual understanding. Teaching methods were whether or not to provide students with propositional information, and learning strategies were self-explaining the learning material and explaining in pairs. The results indicate that prior knowledge facilitates propositional knowledge development and leads to differential effects of teaching and learning methods on conceptual understanding: Only low prior knowledge students profit from additional information in the learning task and/or explaining in pairs. An implication of these findings is that low prior knowledge students should be guided into the subject matter by means of working in pairs on learning tasks that comprise additional information. Once students have developed more knowledge of the subject matter, they should be stimulated to work individually on learning tasks that do not comprise additional information. 相似文献

This study investigated the effects of four instructional methods on cognitive load, propositional knowledge, and conceptual
understanding of statistics, for low prior knowledge students and for high prior knowledge students. The instructional methods
were (1) a reading-only control condition, (2) answering open-ended questions, (3) answering open-ended questions and formulating
arguments, and (4) studying worked-out examples of the type of arguments students in the third group had to formulate themselves.
The results indicate that high prior knowledge students develop more propositional knowledge of statistics than low prior
knowledge students. With regard to conceptual understanding, the results indicate an expertise reversal effect: low prior
knowledge students learn most from studying worked-out examples, whereas high prior knowledge students profit most from formulating
arguments. Thus, novice students should be guided into the subject matter by means of worked-out examples. As soon as students
have developed more knowledge of the subject matter, they should be provided with learning tasks that stimulate students to
solve problems by formulating arguments. 相似文献

The purpose of this paper is to investigate the impact of problem-based learning (PBL) on freshmen engineering students’ beliefs about physics and physics learning (referred to as epistemological beliefs) and conceptual understanding of physics. The multiple-choice test of energy and momentum concepts and the Colorado learning attitudes about science survey were used to collect the data. The sample consisted of 142 students enrolled in the PBL and traditional lecture classes in the engineering faculty of a state university in Turkey. The analyses showed that the PBL group obtained significantly higher conceptual learning gains than the traditional group and the change (improvement) in the PBL group students’ beliefs from the pre- to post test were significantly larger than that of the traditional group. The results revealed that beliefs were correlated with conceptual understanding. Suggestions are presented regarding the implementation of the PBL approach. 相似文献

The effect of group size in problem-based learning(PBL) on the problem-solving skill, self-directedness,and technical knowledge of 72 students in a dentaleducation program was examined. Pretest measures onself-directedness and technical knowledge wereadministered to the 72 students. Equal numbers ofstudents with low, medium, and high levels ofself-directedness were randomly assigned to small,medium, and large PBL groups. Students thenparticipated in a three-week PBL experience, whichinvolved analyzing a patient case. After PBL wascompleted, posttest measures on self-directedness,technical knowledge, and problem-solving skill wereassessed. Students' reactions to the PBL experiencewere also measured. Analysis of the data found thatthe development of self-directedness varied with groupsize. Students' self-directedness increased in smalland medium size groups, but decreased in large groups. A significant difference was found between the mediumand large groups on this measure. Furthermore,students in small groups rated 5 of 12 aspects of PBLsignificantly higher than did those in large groups,and students in medium size groups rated 10 of 12aspects of PBL significantly higher than did those inlarge groups. Implications of these findings forinstructional design theory, practice, and researchare discussed. 相似文献

For a structural engineer, effective communication and interaction with architects cannot be underestimated as a key skill to success throughout their professional career. Structural engineers and architects have to share a common language and understanding of each other in order to achieve the most desirable architectural and structural designs. This interaction and engagement develops during their professional career but needs to be nurtured during their undergraduate studies. The objective of this paper is to present the strategies employed to engage higher order thinking in structural engineering students in order to help them solve complex problem-based learning (PBL) design scenarios presented by architecture students. The strategies employed were applied in the experimental setting of an undergraduate module in structural engineering at Queen’s University Belfast in the UK. The strategies employed were active learning to engage with content knowledge, the use of physical conceptual structural models to reinforce key concepts and finally, reinforcing the need for hand sketching of ideas to promote higher order problem-solving. The strategies employed were evaluated through student survey, student feedback and module facilitator (this author) reflection. The strategies were qualitatively perceived by the tutor and quantitatively evaluated by students in a cross-sectional study to help interaction with the architecture students, aid interdisciplinary learning and help students creatively solve problems (through higher order thinking). The students clearly enjoyed this module and in particular interacting with structural engineering tutors and students from another discipline. 相似文献

A sociocultural view of learning proposes that learning involves becoming enculturated into a community of practice. A step
along the way is learning to use the specialized language of such a community, as language is a crucial tool that regulates
participation, mediates cognition and plays a central role in the development of thought. Problem-based learning (PBL), with
its emphasis on collaborative discourse, provides opportunities for students to develop the conceptual language of a discipline,
which in turn affects cognition. In a problem-based undergraduate Educational Psychology course, many psychological theories,
concepts and principles are introduced to pre-service teachers. During the course, as students learn through problem solving,
they engage with new knowledge. This evolving knowledge requires new discourse structures that will allow students to express
their new ideas and that will ultimately structure students' ways of knowing. The content of group and individual artifacts
is analyzed to examine how PBL influences students' language and knowledge development over the course of the semester in
an Educational Psychology class (n = 34). The goal of this paper is to present these analyses and to discuss how the change affects students' language and knowledge. 相似文献

This study aims to explore how high school students collaboratively solve problems in a web problem-based learning (WPBL) system in an 8-week digital logic course using discourse analysis. Employing in-depth interviews, this study also investigated the students' attitudes toward the WPBL system. The number of teaching assistants' responses had a negative relationship with the number of peer responses. Regarding dialogue quality, extended questions and brainstorming stimulated each other. Elaboration facilitated problem solving, whereas organizing knowledge from books or websites decreased reflection. Students affirmed the usefulness and effectiveness of the web system because it created an interactive, flexible, comfortable and collaborative learning environment. 相似文献

Medical students often have initial understanding concerning medical domains, such as the central cardiovascular system (CCVS), when they enter the study programme. These notions may to some extent be in conflict with scientific understanding, which can be seen as a challenge for medical teaching. Hence, the purpose of this study was to analyse what kind of initial mental models students have about the CCVS and how these models change after a course. Further, we were interested in how medical students evaluate the role of problem-based learning (PBL)-enriched conventional instruction in their learning of the CCVS. Pre- and posttests consisting of a drawing task were conducted with 60 Finnish medical students. Additionally, problem-based learning and course evaluation questionnaires were administered. Results show that one-third of the students had misconceptions such as single-loop concepts in understanding the CCVS before the course. Although the instruction seems to support conceptual change, 10 % of the students did not reach a scientific model. In their evaluations of the learning environment, the students appreciated working in small groups in addition to lectures. Sixty-five percent of the students considered PBL an effective learning method, whereas the rest of the students found it ineffective. In sum, although most of the first-year medical students reached an adequate representation of the central cardiovascular system, too many seem to have resistant misconceptions. Hence, in developing learning environments that support students’ conceptual change in the medical domain, students’ prior knowledge and perceptions of learning environments need to be taken into account. 相似文献

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 aimed to explore how vocational high school students transfer knowledge through a problem-based learning (PBL) Internet platform. A PBL Internet platform was provided to 33 sophomore mechanical engineering students for a 6-week teaching experiment. A survey questionnaire, observation and interview were research instruments. The findings include: 1) factual, conceptual and process knowledge are the major types of knowledge and the sources of knowledge transfer (KT) include students, instructors and industries, but may be acquired differently depending on the level of problem-solving needs; 2) students’ KT includes highly experienced tacit knowledge and more concrete explicit knowledge; 3) students’ attitudes toward the six domains of using the PBL Internet platform all show positive significance, including the platform, the platform instructors, the platform mobility, online interaction, the PBL and the platform interface mechanism of students’ perceptions; 4) the capability and the willingness for KT in instructors, industries and students all have some impact on the effectiveness of KT. 相似文献

Learning can be seen as a task-oriented process which often requires the reorganization of existing knowledge, usually referred to as conceptual change. This paper describes a theoretical framework for the analysis of conceptual change that considers conceptual knowledge as a generative cognitive tool for the creation of more specific mental representations — propositional symbolic structures and analog mental models. According to this view, conceptual change is based on a task-oriented interaction between these different kinds of mental representations. The assumption is made that it is possible to foster conceptual change by presenting to students well-defined tasks that stimulate the construction of elaborated mental models as well as an intensive interaction between these models and the corresponding propositional representations. In order to test this assumption an empirical study was conducted, in which subjects had to express their prior knowledge about a complex subject matter from the field of geography (time differences on the earth), which contained various conceptual deficits. The subjects were then randomly assigned to different groups who received the same learning material but had to solve different learning tasks requiring differently structured mental models. Afterwards, the subjects were asked to express their knowledge about the subject matter again and were tested for understanding with a comprehension test. The results support the view that a task-oriented interaction between propositional structures and mental models can help learners to evaluate the consistency of their conceptual knowledge. Accordingly, conceptual deficits result in the formation of mental models with an inadequate structure. Such deficits can be detected if the respective model is used in a sufficiently variable way, whereas they can remain unnoticed if it is used in a limited manner. 相似文献

When inquiry-based learning is designed for a collaborative context, the interactions that arise in the learning environment can become fairly complex. While the learning effectiveness of such learning environments has been reported in the literature, there have been fewer studies on the students’ learning processes. To address this, the article presents a study of science learning in a computer-supported learning environment called Collaborative Science Inquiry (CSI), which integrates guided inquiry principles for activity design, employs modelling and visualisation tools for promoting conceptual understanding and incorporates key computer-supported collaborative learning (CSCL) elements for enabling students’ collaboration. With the aim of understanding the process of students’ conceptual changes supported by the CSI learning environment as used in a secondary school, data on students’ test achievements, responses to learning tasks and peer discussions in collaboration were collected, analysed and discussed. The results of the qualitative and quantitative data analysis indicated that guided inquiry coupled with CSCL elements facilitated by the CSI system can engage students in inquiry activities and promote their conceptual understanding in a progressive way. 相似文献

Medical schools are increasingly looking to case-based formats such as problem-based learning (PBL) for their medical students. However, the effects of PBL have not been adequately assessed for an informed decision. An approach to assessment should consider not just the knowledge outcomes expected of all students, but should be tailored to the theoretical goals of PBL: clinical reasoning, integration of scientific and clinical knowledge, and lifelong learning skills. This means that problem-solving processes as well as products need to be measured. In addition, cognitive measures associated with expert performance can be used to assess the extent to which PBL affects the development of expertise. In this study, students taking an elective in PBL were compared with students taking other electives on a realistic pathophysiological explanation task. The problem-solving protocols were examined for coherence, use of science concepts, strategy use, and self-directed learning. The results indicate that cognitive measures can be used to distinguish students who have participated in PBL from their counterparts in terms of knowledge, reasoning, and learning strategies. This suggests that such measures may play a meaningful role in assessment of student learning. 相似文献

This study investigated the effects of problem-based learning (PBL) on knowledge acquisition and knowledge retention in a controlled experiment in a lab setting. Eighty-eight first-year psychology students were randomly assigned to either a PBL condition, a lecture condition, or a self-study condition. All participants had the opportunity to study the same text. Their knowledge acquisition was tested on both an immediate post-test and a delayed post-test, one week later. The results showed beneficial effects for the PBL group on the immediate and the delayed test compared to the lecture group. There were no differences between knowledge acquisition scores for the self-study condition and either of the other conditions. Moreover, no differences on knowledge retention were shown, because the decline in performance over time was equal in all conditions. In conclusion, the present study provides experimentally based evidence of the disadvantageous effects of instruction through lectures compared to PBL. 相似文献

复习课是初中科学课堂的重要课型之一,是教师指导学生温习知识,强化知识,加深理解,使知识系统化并进行重新再建构的过程。然而,在课堂实践中,教师往往只注重知识点的简单回顾,而缺少对知识间联系的探究;只注重解几道题,而缺少方法的梳理;只注重知识本身,而缺少与实际生活的联系,使课堂显得沉闷,学生缺乏主动参与,也缺乏知识的灵活应用,导致复习效果不太理想,也无法促进学生的发展。有实效性的课堂一般都有较好的教学主线,有利于突出重点,把握内容和方法,让学生乐于参与。其中,基于问题解决、方法梳理、知识建构这三种方法是常见的主线构建模式,通过日常课堂观摩和教学实践,发现上述三种模式确实有利于提升课堂实效。 相似文献

Meeting International Society for Technology in Education competencies creates a challenge for teachers. The authors provide a problem-based video framework that guides teachers in enhancing 21st century skills to meet those competencies. To keep the focus on the content, the authors suggest teaching the technology skills only at the point the students need to use them. An example is provided on how the problem-based video framework was applied in a higher education setting. The benefits and challenges for using video within a problem-based learning context are discussed. 相似文献
