Many educational researchers have investigated how best to support conceptual learning in science education. In this study, the aim was to design learning materials using Physlets, small computer simulations, and to evaluate the effectiveness of these materials in supporting conceptual learning in secondary school physics. Students were taught in two different physics courses (conditions): one group of students (n = 40) was taught using Physlet-based learning materials, and the other (n = 40) was taught using expository instruction. To evaluate the designed materials, we assessed students’ thinking skills in relation to physics after the course and analyzed the results using an independent t test, multiple regression analyses, and one-way analysis of covariance. The results showed better thinking skills among students in the experimental group and supported a clear relationship between the physics course using Physlet-based materials and this improvement (p < 0.05). These results indicate that properly designed Physlet-based materials can effectively support conceptual learning.  相似文献

Formative Assessment (FA) refers to eliciting evidence about students’ understanding and using the information to support learning, e.?g. via individual feedback. There is evidence that FA fosters students’ motivation, but less is known about the underlying processes. The present study investigates direct effects of FA on intrinsic motivation as well as the mediating role of students’ perceived competence, drawing on Deci and Ryan’s self-determination theory. In a randomized, controlled trial, primary school teachers were either assigned to an FA training (n?=?17) or to a control group (CG; n?=?11). All teachers then taught two science units in their classrooms (FA: n?=?319 students, CG: n?=?232). Multilevel regression analyses showed a higher perceived competence and a marginally higher intrinsic motivation for FA students after unit 1. After unit 2, both intrinsic motivation and perceived competence were higher in the FA condition, and the impact on intrinsic motivation was significantly mediated by students’ perceived competence after the first unit. These results confirm and extend previous findings on the effectiveness of formative assessment on motivational outcomes.  相似文献

Components of complex systems apply across multiple subject areas, and teaching these components may help students build unifying conceptual links. Students, however, often have difficulty learning these components, and limited research exists to understand what types of interventions may best help improve understanding. We investigated 32 high school students’ understandings of complex systems components and whether an agent-based simulation could improve their understandings. Pretest and posttest essays were coded for changes in six components to determine whether students showed more expert thinking about the complex system of the Chesapeake Bay watershed. Results showed significant improvement for the components Emergence (r = .26, p = .03), Order (r = .37, p = .002), and Tradeoffs (r = .44, p = .001). Implications include that the experiential nature of the simulation has the potential to support conceptual change for some complex systems components, presenting a promising option for complex systems instruction.  相似文献

This paper presents the experience of going to scale of Escuela Nueva, an educational innovation that started in Colombia and has influenced educational policy in several countries around the world during the last 30 years. The paper is based on the experience of the leaders of the innovation and its expansion over time. As an insider´s perpective, it relies on the knowledge of senior staff of Fundación Escuela Nueva and on the published evidence and experience accumulated during the decades following the creation of the innovation. The paper describes the context where Escuela Nueva was created and the practices of participating students, teachers, schools administrators and parents when undergoing learning and teaching. It presents the conceptual underpinnings of the innovation, and discusses existing evidence of impact of Escuela Nueva on students, teachers and parents. It then examines the experience of bringing Escuela Nueva to scale, using a three-stage framework: learning to be effective, learning to be efficient and learning to expand. The paper then discusses key factors for success, and the challenges of scale, impact and sustainability, and advances the argument that good design, adequate implementation and sustained support are essential to take an innovation to scale. To conclude, the following four key lessons of Escuela Nueva to the educational change field are discussed : (1) Teachers and students need to be the key actors of the change; (2) the proposed improvements have to be easily replicable within existing conditions; (3) the attitudinal change of teachers is positively affected as a result of demonstrating that the model was feasible, a good fit for its beneficiaries and that they could do it; and (4) a systemic approach is necessary to impact simultaneously on the critical factors of success.  相似文献

Definitions of formative assessment include assessment, feedback and differentiated instruction as key components. We investigated the effects of prepared teaching materials designed to support teachers using learning progress assessment (LPA) to give feedback and adapt differentiated instruction. We also examined to what extend this modular approach can be implemented in regular reading lessons in third grade. In a three-group design all teachers (N?=?44, N?=?945 students) employed a computer-based LPA tool, while teachers in two conditions additionally received prepared feedback material (FB) or feedback and reading instruction material (FB+FM), to support the implementation of the different components of formative assessment. Over the course of one schoolyear, we assessed the implementation outcomes using questionnaires as well as students’ reading achievement and further student outcomes. While acceptability is high, teacher ratings of feasibility are low. In comparison to the LPA group, the additional support in form of prepared materials had no effects on student outcomes. Results are discussed regarding the question of how teachers can optimally be supported in using formative assessment.  相似文献

The main purpose of this study was to investigate the effects of cooperative learning based on conceptual change approach instruction on ninth-grade students’ understanding in chemical bonding concepts compared to traditional instruction. Seventy-two ninth-grade students from two intact chemistry classes taught by the same teacher in a public high school participated in the study. The classes were randomly assigned as the experimental and control group. The control group (N?=?35) was taught by traditional instruction while the experimental group (N?=?37) was taught cooperative learning based on conceptual change approach instruction. Chemical Bonding Concept Test (CBCT) was used as pre- and post-test to define students’ understanding of chemical bonding concepts. After treatment, students’ interviews were conducted to observe more information about their responses. Moreover, students from experimental groups were interviewed to obtain information about students’ perceptions on cooperative work experiences. The results from ANCOVA showed that cooperative learning based on conceptual change approach instruction led to better acquisition of scientific conceptions related to chemical bonding concepts than traditional instruction. Interview results demonstrated that the students in the experimental group had better understanding and fewer misconceptions in chemical bonding concepts than those in the control group. Moreover, interviews about treatment indicated that this treatment helped students’ learning and increased their learning motivation and their social skills.  相似文献

The need to enhance students’ learning outcomes has become integral in secondary schools in developing countries due to increased students enrollment. Research has shown that the strategies utilized in teaching secondary school students have significant influence on their learning outcomes. At present in Nigeria, public secondary schools have not been deploying learning technologies to teach students despite the surge in enrollment. This study, therefore, determined the effects of computer-aided and blended teaching strategies on students’ achievement in civic education concepts in mountain learning ecologies. The study adopted the pretest-posttest, control group, quasi-experimental design using 3 × 2 × 3 factorial matrix. Seventy-eight students from six intact classes in secondary schools in Ondo State were selected for the study and randomly assigned to experimental and control groups. Five instruments used were: Students’ Knowledge of Civic Education Test (r = 0.78), Academic Ability Test (r = 0.72), Online and Blended Teaching Instructional Guides for experimental groups, Conventional Lecture Method Guide for the control group and Teaching Strategies Evaluation Sheet. One hypothesis was tested at 0.05 level of significance. Data was subjected to Analysis of Covariance, Estimated Marginal Means, and Scheffe’s Pairwise Comparison. There was a significant effect of treatment on students’ achievement in Civic Education concepts (F (2; 61) = 4.93, p < 0.05; η 2  = .14). The students exposed to Computer-aided teaching programme had higher adjusted achievement mean score (\( \overline{x} \)= 27.86), than the blended instructional strategy group (\( \overline{x} \)= 23.06), and the control group (\( \overline{x} \)= 18.69). It was, therefore, recommended that teachers in secondary schools in mountainous locations should explore the benefits of teaching with Information and Communication Technology based strategies in civic education classrooms.  相似文献

In the present paper, we report on the idea of exchanging educational innovations across European countries aiming to shed light on the following question: how feasible and useful is it to transfer an innovation across different national educational settings? The innovation, in this case, Inquiry-Based Teaching Learning Sequences, is recognized as a crucial component of renewal science teaching in European countries. Two local working groups from two different Universities, in Finland and Greece, were created consisting of researchers and experienced primary teachers. The transfer from Greece to Finland was rather challenging because of the differences between the two educational contexts. The initial, as well as the revised Teaching Learning Sequence, were implemented for 11–12-year-old students including the content to be taught, that is Floating-Sinking phenomena and density, and the learning environment aspects such as learning Control of Variables Strategy. A combination of qualitative and quantitative research methods was implemented in order to formulate concrete recommendations on feasible and useful aspect. The feasible aspect adduces answers to the query of “how” this transfer worked in practice. Concerning this aspect, the recognition of what is innovative for each national partner was recognized as a crucial factor for the design and revision of both Teaching Learning Sequences. The useful aspect illuminates students’ improvement in the achievement of conceptual as well as procedural knowledge. The results revealed that the psychological paths that bring about this success are ecumenical and independent of the history of the educational group.  相似文献

Because of ever stricter standards of accountability, science teachers are under an increasing and unrelenting pressure to demonstrate the effects of their teaching on student learning. Econometric perspectives of teacher quality have become normative in assessment of teachers’ work for accountability purposes. These perspectives seek to normalize some key ontological assumptions about teachers and teaching, and thus play an important role in shaping our understanding of the work science teachers do as teachers in their classrooms. In this conceptual paper I examine the ontology of science teaching as embedded in econometric perspectives of teacher quality. Based on Foucault’s articulation of neoliberalism as a discourse of governmentality in his ‘The Birth of Biopolitics’ lectures, I suggest that this ontology corresponds well with the strong and substantivist ontology of work under neoliberalism, and thus could potentially be seen as reflection of the influence of neoliberal ideas in education. Implications of the mainstreaming of an ontology of teaching that is compatible with neoliberalism can be seen in increasing marketization of teaching, ‘teaching evangelism’, and impoverished notions of learning and teaching. A shift of focus from teacher quality to quality of teaching and building conceptual models of teaching based on relational ontologies deserve to be explored as important steps in preserving critical and socially just conceptions of science teaching in neoliberal times.  相似文献

This study examines the effects of including interactive graphic organizers into a whole-class PowerPoint lesson as an instructional approach intended to improve student engagement and generative learning in schools. A software application was developed and integrated into PowerPoint that makes it possible for the instructor to fill in empty graphic organizers during PowerPoint projection mode. The participants were 152 fourth-grade students selected from three schools that were grouped in four classrooms. Each classroom was divided in two groups—graphic organizer and content-based. The graphic organizer group was taught using an 11-slide PowerPoint presentation on a social study topic that included two empty graphic organizers plus two additional slides explaining how to make a comparison. The content-based group was taught using the same presentation but without these additional slides plus a set of questions students had to answer as a class activity. The lessons were recorded and the verbal statements between instructor and students examined using the Flanders Interaction Analysis System. Results indicated significant differences in how instructors and students interacted in each group, including more questions asked by teachers (d?=?1.99) and more students participating in the classroom discussion in the graphic organizer group (d?=?1.76). Learning outcomes showed that the graphic organizer group outperformed the content-based group on a memory test (d?=?.45) and a comprehension test (d?=?.44). These results encourage the use of graphic organizers as an instructional approach, and are consistent with a generative theory of learning.  相似文献

Teaching systematic phonics effectively to beginning readers requires specialized knowledge and training which many primary grade teachers lack. The current study examined effects of a year-long mentoring program to improve teachers’ knowledge and effectiveness in teaching phonics and the extent that it improved students’ achievement in reading and spelling. Teachers in urban, lower SES schools completed a 45 h course followed by 90 h of in-school training. Mentors (N = 29) worked with kindergarten, 1st, 2nd, and 3rd grade teachers (N = 69) twice a week for 30 weeks during the year. Each visit included a 45 min prep period plus 45 min of modeling and feedback in the classroom. Mentors taught teachers how to provide systematic phonics instruction to their students (N = 1,336). Monthly ratings by mentors revealed that teachers improved their phonics teaching skills with many reaching the highest ratings by May. Teachers who were non-native speakers of English took a bit longer to learn the English sound system for letters, mainly because they lacked sufficient knowledge of English sounds and had to learn them. Given the increasing diversity of the teacher work force, future research is needed to study this difficulty, its solution, and impact on students. Teachers’ agreement with principles of phonics instruction remained strong or increased from fall to spring. Students’ reading and spelling skills showed large gains during the year and far exceeded effect sizes from comparable data sources. Students met grade-level expectations at the end of kindergarten and first grade but fell short in second and third grades. General education students outperformed bilingual/ELL and special needs students although all subgroups made large gains. Findings reveal the effectiveness of an intensive mentoring model of professional development applied to a subject that is difficult to teach and to a student population known for lower reading achievement. Findings point to the need for better pre-service teacher preparation coupled with appropriate curricula and PD from districts in order to improve students’ reading achievement.  相似文献

In understanding upper secondary school students’ interpretations of information in graphical representations of a distance–time graph and an ECG graph, little attention has been paid to the analysis of the condition of the conceptual development related to their utterances. Understanding this better can help improve the teaching of interpretations of information in graphical representations of different situations. This paper integrates results from 2 studies and 3 theoretical perspectives: Tall and Vinner’s theoretical perspectives on learning, Chi’s ontological perspectives on conceptual development and Friel’s theoretical perspectives on interpretation of graphical information. The findings provide evidence to support the conjecture that iconic interpretations could be stimulated and generated as a result of student categorisation of a distance–time graph as an event, when in fact the graph is being used to describe and communicate a process. The outcome further indicates that students found a resemblance between the ECG diagram and the periodic function of f(x) = sin(x).  相似文献

Team teaching is becoming more common in undergraduate programmes of study although the relative merits to the more traditional individually taught courses have not been determined for best practice. For this study, 15 final-year undergraduate computer science students were interviewed to gain insight into their learning experiences. A thematic analysis of the interview data identified the perceived advantages and disadvantages of each mode of teaching. The advantages of individually taught courses included: consistency of content delivery and advice, familiarity with the lecturer’s teaching style and better continuity of the subject content. The disadvantage of individually taught modules included missing knowledge, compared to a team approach. Advantages of team-taught modules included: greater insight into a topic delivered by multiple team members. Disadvantages included: content overlap, conflicting messages relating to assessment, team members not taking ownership of their roles and responsibilities and a belief that overall team failure is worse than individual failure to deliver a module well. The results revealed that individually taught modules were generally preferred to team-taught modules. A set of best practice recommendations are proposed to address the challenges when delivering team-taught teaching and become more student focused.  相似文献

Designing and deploying programming courses is undoubtedly a challenging task. In this paper, an attempt to analyze important aspects of a sequence of two courses on imperative-procedural and object-oriented programming in a non-CS majors Department is made. This analysis is based on a questionnaire filled in by fifty students in a voluntary basis. The issues of the programming courses that are investigated refer to: the strategy selected for the introduction to programming; the sequence of the programming techniques and languages taught and the transition from the one to the other; students’ difficulties with programming in general and with imperative-procedural and object-oriented programming in specific; the teaching and learning design of both courses; and the material that students rely on for learning programming. Based on the analysis of students’ replies on the questionnaire, related work and the instructor’s experience on teaching the courses, conclusions are drawn regarding all the aforementioned aspects of designing and deploying programming courses. The main contribution of the paper is the fact that all the important and interrelated aspects of a sequence of two programming courses are investigated in conjunction, providing realistic implications and guidelines for improving the quality and effectiveness of existing programming courses and designing and deploying new courses. The main results refer to the usage of a pseudo-language for an introduction to programming, the transition from procedural to object-oriented programming, the intrinsic difficulties of learning programming, and practices for a more successful teaching and learning design of programming courses.  相似文献

The following study aims to explore whether a video- and problem-based learning (PBL) environment can be improved using cognitive tools. Our hypothesis is that direct instructions in a PBL setting enhance pre-service teachers’ learning outcomes in classroom management. To answer this research question, we implemented a pre-post-design within which we assigned 237 master students to two learning environments: Classic problem-based learning (PBL), where students acquired central theoretical concepts and empirical findings on dealing with disruptions in groups (n = 113) or instructed problem-based learning (I-PBL), where students received extensive theoretical instructions (n = 124) during the first two seminar sessions. In the framework of a longitudinal self-report assessment we found that (1) teacher self-efficacy in the subscales “student engagement”, “instruction” and “classroom management competencies” increased in students of both groups. The highest increase was found in classroom management competencies. (2) In the evaluation with an objective measure students participating in the I?PBL group showed greater knowledge than students in the PBL group (multiple-choice test), and (3) regarding motivational processes students in the PBL group reported a higher degree of identification than students in the I?PBL group.  相似文献

To address the need for effective, efficient ways to apply active learning in undergraduate biology courses, in this paper, we propose a problem-centered approach that utilizes supplemental web-based instructional materials based on principles of active learning. We compared two supplementary web-based modules using active learning strategies: the first used Merrill’s First Principles of Instruction as a framework for organizing multiple active learning strategies; the second used a traditional web-based approach. Results indicated that (a) the First Principles group gained significantly from pretest to posttest at the Remember level (t(40) = ?1.432, p = 0.08, ES = 0.4) and at the Problem Solving level (U = 142.5, N1 = 21, N2 = 21, p = .02, ES = 0.7) and (b) the Traditional group gained significantly from pretest to posttest at the Remember level (t(36) = 1.762, p = 0.043, ES = 0.6). Those in the First Principles group were significantly more likely than the traditional group to be confident in their ability to solve problems in the future (χ2 (2, N = 40) = 3.585, p = 0.09).  相似文献

This research focuses on Finnish students’ (n?=?84) experiences of using personal iPads in their studies through 3 years of upper secondary schooling. It is based on results from one of the first schools in Finland where all the new students were provided with iPads at the start of their studies. Data consists of: (i) 127 short stories written by students about how they would advise a new teacher and a new student to use iPads in teaching and learning, and (ii) four group discussions on the same topics. Qualitative thematic analysis of the data was guided by the TPACK framework. Results suggest that: (i) teachers’ pedagogical approaches changed little in response to the new devices and remained largely teacher-centred, and (ii) students do not have the confidence to radically change learning styles to take advantage of the affordances of the devices. The value that iPads add to teaching and learning is difficult to quantify because of the complex and often conflicting factors involved. Overall, the findings imply that teachers’ TPACK is generally resistant to change and students’ proto-TPACK is insufficiently developed to initiate change. An approach that systematically develops both students’ and teachers’ TPACK is advocated.  相似文献

This study deals with the school instruction of the concept of weight. The historical review reveals the major steps in changing weight definition reflecting the epistemological changes in physics. The latest change drawing on the operation of weighing has been not widely copied into physics education. We compared the older instruction based on the gravitational definition of weight with the newer one based on the operational definition. The experimental teaching was applied in two versions, simpler and extended. The study examined the impact of this instruction on the middle school students in regular teaching environment. The experiment involved three groups (N = 486) of 14-year-old students (ninth grade). The assessment drew on a written questionnaire and personal interviews. The elicited schemes of conceptual knowledge allowed to evaluate the impact on students’ pertinent knowledge. The advantage of the new teaching manifested itself in the significant decrease of the well-known misconceptions such as “space causes weightlessness,” “weight is an unchanged property of the body considered,” and “heavier objects fall faster”. The twofold advantage—epistemological and conceptual—of the operational definition of weight supports the correspondent curricular changes of its adoption.  相似文献

Formative assessment is considered to be a promising teaching practice for promoting teaching and learning processes. The implementation of teaching practices into instruction involves intervening with a learning environment that is characterised by certain features of instructional quality. Our study aims to contribute to the understanding of formative assessment by analysing the interplay between a formative assessment intervention and aspects of general instructional quality. In a quasi-experimental study design, 15 teachers participated in a control group (n = 361 students) and 20 teachers in the intervention classes (n = 498 students) implemented a curriculum-embedded formative assessment tool in their ninth-grade mathematics classes. No effects were found for the intervention on the assessed aspects of general instructional quality (process-oriented instruction, teacher–student relationship, effective use of instructional time). However, multilevel regression analyses revealed an interaction effect between the intervention and process-orientation and the effective use of instruction time. Our findings suggest that implementing formative assessment tools do not seem to suffice regarding changes in general instructional quality, but that an intervention with detailed material and guidelines can counterbalance effects of instructional quality, fostering students’ achievement in classes with lower degrees of process orientation and a less effective use of instructional time.  相似文献
