The main task of an educational system is to generate instructional situations which induce students to learn knowledge and problem solving abilities as applied to a cognitive domain.
To this end, an instructional dialogue must be seen as a process aimed at making student and teacher learn from each other: the student has to learn the subject matter from the teacher, while the teacher has in turn to learn from the student how to regulate instructional interaction. The process relies on different kinds of expert knowledge: experience of the domain, about the actual student, and of teaching methods and objectives. This means that an instructional dialogue cannot be realised without an explicit representation of all the kinds of knowledge involved.
Research has established that Knowledge Based Educational Systems (KBESs) can be the keystone in building effective learning tools, but because of the difficulty in realising a system of this kind, most existing systems are prototypes and are intended only as workbenches for the computational analysis of educational processes.
This paper analyses the main problems which underlie the realisation of such systems, with reference to research into knowledge based systems intended for use with teaching/learning mathematics.  相似文献

Problem-Based Learning: What and How Do Students Learn?   总被引：22，自引：0，他引：22  
Problem-based approaches to learning have a long history of advocating experience-based education. Psychological research and theory suggests that by having students learn through the experience of solving problems, they can learn both content and thinking strategies. Problem-based learning (PBL) is an instructional method in which students learn through facilitated problem solving. In PBL, student learning centers on a complex problem that does not have a single correct answer. Students work in collaborative groups to identify what they need to learn in order to solve a problem. They engage in self-directed learning (SDL) and then apply their new knowledge to the problem and reflect on what they learned and the effectiveness of the strategies employed. The teacher acts to facilitate the learning process rather than to provide knowledge. The goals of PBL include helping students develop 1) flexible knowledge, 2) effective problem-solving skills, 3) SDL skills, 4) effective collaboration skills, and 5) intrinsic motivation. This article discusses the nature of learning in PBL and examines the empirical evidence supporting it. There is considerable research on the first 3 goals of PBL but little on the last 2. Moreover, minimal research has been conducted outside medical and gifted education. Understanding how these goals are achieved with less skilled learners is an important part of a research agenda for PBL. The evidence suggests that PBL is an instructional approach that offers the potential to help students develop flexible understanding and lifelong learning skills.  相似文献

The purpose of this study was to examine how 1:1 laptop initiative affected student learning at a selected rural Midwestern high school. A total of 105 high school students enrolled in 10th–12th grades during the 2008–2009 school year participated in the study. A survey instrument created by the Mitchell Institute was modified and used to collect data on student perceptions and faculty perceptions of the impact of 1:1 laptop computing on student learning and instructional integration of technology in education. Study findings suggest that integration of 1:1 laptop computing positively impacts student academic engagement and student learning. Therefore, there is need for teachers to implement appropriate computing practices to enhance student learning. Additionally, teachers need to collaborate with their students to learn and understand various instructional technology applications beyond basic Internet browsing and word processing.  相似文献

Double-block instruction has become a popular strategy for supporting struggling mathematics students in algebra I. Despite its widespread adoption, little consistent evidence supports the attributes of a successful double-block design or the effectiveness of this instructional strategy. In this study, the authors examine a pilot implementation of a double-block strategy—instantiated in the program Intensified Algebra—that combines core algebra content with insights from research on how students learn mathematics and explicit noncognitive supports focused on key attitudes, beliefs, and behaviors essential to student success. The results of the study show that, when implemented with fidelity, participation in the program significantly increased student achievement on the state end-of-course algebra I assessment.  相似文献

The major purpose of the study was to examine what constitutes effective teaching as defined by measured increases in student learning with a focus on the instructional behaviors and practices. Ordinary least squares (OLS) regression analyses and hierarchical linear modeling (HLM) were used to identify teacher effectiveness levels while controlling for student-level and class/school-level variables. Actual achievement of 1936 third grade students in 85 classrooms on the Virginia Standards of Learning (SOL) Assessment results in English, Mathematics, Social Studies, and Science were compared to expected achievement resulting in an indicator of teacher effectiveness. Based on student learning gains, teachers were divided into quartiles. The statistical modeling approach facilitated comparisons of outcomes that were free of influences of identified extraneous variables. A double blind design was selected for in-depth cross-case studies with teachers from the highest quartile representing highly effective teachers (N?=?5) and the lowest quartile the less effective teachers (N?=?6). The observation team assessed the third grade teachers (N?=?11) based 20 categories within four domains: instruction, student assessment, classroom management, and personal qualities. Key findings indicate that effective teachers scored higher across the four domains. Additionally, effective teachers tended to ask a greater number of higher level (e.g., analysis) questions and had fewer incidences of off-task behavior than ineffective teachers. The exploratory study identified instructional behaviors and practices of teachers that result in higher student learning gains.  相似文献

Well-designed instructional videos are powerful tools for helping students learn and prompting students to use generative strategies while learning from videos further bolsters their effectiveness. However, little is known about how individual differences in motivational factors, such as achievement goals, relate to how students learn within multimedia environments that include instructional videos and generative strategies. Therefore, in this study, we explored how achievement goals predicted undergraduate students’ behaviors when learning with instructional videos that required students to answer practice questions between videos, as well as how those activities predicted subsequent unit exam performance one week later. Additionally, we tested the best measurement models for modeling achievement goals between traditional confirmatory factor analysis and bifactor confirmatory factor analysis. The bifactor model fit our data best and was used for all subsequent analyses. Results indicated that stronger mastery goal endorsement predicted performance on the practice questions in the multimedia learning environment, which in turn positively predicted unit exam performance. In addition, students’ time spent watching videos positively predicted practice question performance. Taken together, this research emphasizes the availing role of adaptive motivations, like mastery goals, in learning from instructional videos that prompt the use of generative learning strategies.  相似文献

Process-oriented instruction is defined as instruction aimed at teaching thinking strategies and domain-specific knowledge in coherence. This new conception of instruction is derived from psychological research on the way students learn and on the interplay between self-regulation and external regulation of learning. In the research reported here the learning effects of a process-oriented instructional program for university students were empirically studied. The instructional program consisted of a diagnostic learning style instrument, a learning guide and tutorials. The results showed that the majority of students reported significant general, knowledge, insight and application learning effects. The program effects were typified more by integrating and making usable metacognitive knowledge already present, than by increasing knowledge about new subjects. Evidence for transfer effects was obtained because participants in the program scored better than non-participants on two exams of another course. The learning effects were higher than the effects of an preliminary version of the program implemented with students from an open university. These results support the importance of the process-oriented instructional model. The linking of a thorough diagnosis of personal learning styles to individually tailored instructional measures, turned out to be a powerful way to activate students to reflect on their learning and to develop their mental models of learning.  相似文献

This paper describes a study investigating the characteristics of teacher behavior under two different instructional management models and their differential effects on students under an individualized early learning program. The study investigated the effectiveness and feasibility of using observational techniques in classroom settings to obtain information about student learning processes and outcomes necessary for implementing an adaptive early education model. Observational data, records of student progress in he curricula, and records of student learning activities were collected systematically in order to characterize the classroom behaviors of students and teachers.Learning Research and Development Center University of PittsburghThe research reported herein was supported in part by a grant from the Ford Foundation, and in part by a grant from the United States Office of Education to the Learning Research and Development Center.

Examining learning is a wide and open topic. If we pay attention to learning as achieving some aims and goals defined before, we need a broader and more precise context, an instructional process. This consists of interaction between a teacher and the students. It is based on particular relationships between the teacher, the student and the content that is studied in the instructional process. The human relationship between the teacher and the students is a pedagogical relation and it is regulated by the pedagogical context. Fundamental to learning is, however, how the student meets the content to be learnt, the didactic relation. This relation is invisible by nature. To organise this relation belongs to the expertise of the teacher. The student learning is supposed to take place in the didactic relation of the instructional process.  相似文献

Abstract

In this exploratory phenomenological study, part of a larger mixed-design research project, the authors examined teacher and student roles in, and reactions to, a student-centered instructional geometry program using the Geometer's Sketchpad. Grade 7 students worked for 2 weeks in their regularly scheduled mathematics class on activities that allowed them to explain on-screen relationships among geometric shapes. A companion computer-based instructional tutorial was available as an accessible resource. The class sessions and specific dyads were observed, students surveyed, and teacher and selected students interviewed. Findings centered on 2 overarching themes: issues of power and learning. The teacher had difficulty relinquishing control of the learning environment even though she had agreed to do so. Students, however, liked their new freedom, worked hard, and expressed greater interest in the subject material.  相似文献

This study investigated the relations between teachers’ pedagogical beliefs and students’ self-reported engagement in learning from texts with instructional pictures. Participants were the biology, geography, and German teachers of 46 classes (Grades 5-8) and their students. Teachers’ instructional behaviors and students’ engagement in learning from texts with instructional pictures were assessed by means of student ratings. Teachers’ beliefs about using texts with instructional pictures in their teaching were assessed by a self-report questionnaire. Results showed that the more teachers believed that students should be taught clear strategies on how to learn from texts with instructional pictures the more engagement was reported by their students. A multilevel mediation model showed that the association between teachers’ beliefs and students’ self-reported engagement was mediated by teachers’ perceived instructional behavior.  相似文献

There is evidence that negative correlations between student achievement and their enjoyment of instructional methods exist under certain circumstances. In aptitude‐treatment interaction (ATI) studies where two or more methods are allowed to interact with student aptitudes to predict enjoyment and achievement, it appears that students often report enjoying the method from which they learn the least. Selected ATI studies are reviewed, and an explanation is suggested which may account for the negative correlations between achievement and enjoyment in instructional settings. It appears that students make inaccurate judgments about the amount of effort they will have to expend to achieve maximum learning outcomes. Low ability students typically report liking more permissive instructional methods, apparently because they allow them to maintain a “low profile” so that their failures are not as visible. However, in order to experience maximum achievement low ability students require less permissive methods which lower the information processing load on them. High ability students like more structured methods which they believe will make their efforts more efficient when these lower load methods seem often to interfere with their learning. High ability students seem to learn more from more permissive approaches which allow them to bring their own considerable skills to bear on learning tasks.  相似文献

Innovative reforms in medical education will require instructional tools to support these changes and to give students more flexibility in where and how they learn. At Colorado State University, the software program Virtual Canine Anatomy (VCA) was developed to assist student learning both inside and outside the anatomical laboratory. The program includes interactive anatomical photographs of dissected canine cadavers, dissection instructions with accompanying videos and diagrams, radiographs, and three-dimensional models. There is a need to evaluate the effectiveness of instructional tools like VCA so that decisions on pedagogical delivery can be evidence-based. To measure the impact of VCA on student outcomes in a dissection laboratory, this study compared student attitudes, quiz scores, dissection quality and accuracy, and instructor reliance between students with and without access to VCA. Students with VCA needed less time with teaching assistants (P < 0.01), asked teaching assistants fewer questions (P = 0.04), felt that the dissection was easier (P = 0.02), and were in stronger agreement that they had access to adequate resources (P = 0.02). No differences were found in the dissection quality or accuracy, quiz scores, or attitudes regarding overall enjoyment of the activity between the two groups. This study shows that VCA increases student independence and can be used to enhance anatomical instruction.  相似文献

This project directly involved students in two different models of instructional development. The first model was a Student Consultant program in which faculty selected from a menu of instructional services carried out by students. Typical services included attending class as impartial observers, soliciting feedback from other students on their learning experiences, videotaping class sessions, and evaluating course Web sites. The second model of instructional development was a program of student‐assisted teaching seminars for college faculty. Student Associates helped serve as panelists and facilitators. Assessments of attitudes toward teaching indicated that faculty members viewed both professors and students as collaborators in the classroom as a result of the seminar series.  相似文献

Student behavioral problems pose a myriad of challenges for schools. In this study, we examine the relations among teacher and school‐level constructs (i.e., teacher collaboration, supervision/discipline, instructional management), and student‐related outcomes (i.e., high‐risk behaviors, barriers to learning, student social–behavioral climate). Teachers across 29 high schools, in a large urban school district serving primarily low‐income students, completed self‐report surveys. Multilevel regression was used to test both individual‐ and school‐level predictors of student outcomes. Findings suggest that teacher practices at the individual and school levels are linked to student high‐risk behaviors, barriers to student learning, and school climate. More specifically, findings indicate that better supervision/discipline and instructional management are associated with fewer high‐risk behaviors and barriers to learning. More instructional management is also linked to positive social–behavioral climate. Results from this study highlight the association between teacher practices and a range of student‐related problem behaviors, and suggest that system‐level interventions in the school may have positive effects.  相似文献

Video production offers a way for students to learn content-area knowledge while simultaneously developing technology skills deemed important in contemporary society. Yet, the research has not been examined in a systematic way to reveal how these types of projects are oriented to align to instructional goals or how learning is investigated when they are implemented as part of content-area pedagogy. A scoping study was conducted to review the research literature on implementation of student video production in content-area classrooms. A total of 61 studies published from 2006 through 2017 were selected and analyzed through a systematic process. Findings suggest that video production projects were conducted to meet information, performance, composition, literacy, or creativity learning goals in content-area classrooms. Strategies used to investigate student learning included evaluation of learner perceptions, analysis of the process of creating video, assessment of the final video project, or a combination of these approaches.  相似文献

One of the objectives of the process technology curriculum at Wageningen University is that students learn how to design mathematical models in the context of process engineering, using a systematic problem analysis approach. Students find it difficult to learn to design a model and little material exists to meet this learning objective. For these reasons, a set of digital tools has been developed to support students when learning to design mathematical models. The set of tools enables a process engineering student to do each step in the systematic approach for designing models while providing feedback on the actions of the student.

The current paper describes both the system, the underlying design decisions and how one such case is used in a regular educational setting. Evaluation after use in a regular educational setting shows that students are very positive about the fact that there is feedback on every step of the design process and that there is no need to deal with complicated mathematics.  相似文献

Science Created by You (SCY) learning environments are computer-based environments in which students learn about science topics in the context of addressing a socio-scientific problem. Along their way to a solution for this problem students produce many types of intermediate products or learning objects. SCY learning environments center the entire learning process around creating, sharing, discussing, and re-using these learning objects. This instructional approach requires dedicated instructional designs, which are supplied in the form of what are called pedagogical scenarios. A SCY pedagogical scenario presents the learning process as an organized assembly of elementary learning processes, each associated with a specific learning object and a tool for creating this learning object. Designing a SCY learning environment is basically a two-step procedure: the first step is to select one of the available scenarios, and the second step is to define the domain content. The SCY technical infrastructure then handles the instantiation of the scenario as a SCY computer-based learning environment. In this article we describe the SCY pedagogical design scenarios and report on our experiences in designing four different SCY learning environments.  相似文献
