Ecosystem modeling is a critically important tool for environmental scientists, yet is rarely taught in undergraduate and graduate classrooms. To address this gap, we developed a teaching module that exposes students to a suite of modeling skills and tools (including computer programming, numerical simulation modeling, and distributed computing) that students apply to study how lakes around the globe are experiencing the effects of climate change. In the module, students develop hypotheses about the effects of different climate scenarios on lakes and then test their hypotheses using hundreds of model simulations. We taught the module in a 4-hour workshop and found that participation in the module significantly increased both undergraduate and graduate students’ understanding about climate change effects on lakes. Moreover, participation in the module also significantly increased students’ perceived experience level in using different software, technologies, and modeling tools. By embedding modeling in an environmental science context, non-computer science students were able to successfully use and master technologies that they had previously never been exposed to. Overall, our findings suggest that modeling is a powerful tool for catalyzing student learning on the effects of climate change.  相似文献

Abstract

In parts of the world, including many developing countries, climate variability impacts negatively on agricultural production and natural resource management. Workshops in applied climatology were held in Australia, India, Indonesia and Zimbabwe between 1999 and 2002 to provide farmers and agricultural and meteorological staff a better understanding of the El Niño-Southern Oscillation phenomenon, associated climate variability, its forecast potential and its relevance to their local agriculture system. Most participants saw climate information skills as essential or useful in their work but few had good skills. Through discussions, learning outcomes were established and resource materials developed in Australia were adapted for use in the other countries. Educational course material was developed for workshops and for vocational and tertiary education. This material was developed in multimedia and print format suited to different learning styles. Workshops incorporated sessions on local climate, a climate analysis tool to assist forecasting, application of forecasts, communication and evaluation. Post-workshop surveys demonstrated improved knowledge and skills of participants with a need for further training in risk management strategies relating to agricultural systems. This was identified by a skills audit during the workshops and could form the basis for an advanced training programme.  相似文献

Abstract: The current generation of students coming into food science and engineering programs is very visually oriented from their early experiences. To increase their interest in learning, new and visually appealing teaching materials need to be developed. Two diverse groups of students may be identified based on their math skills. Food science students tend to find it difficult to use mathematics as a problem‐solving tool for food engineering problems. Food engineering students, on the other hand, should be challenged to use emerging mathematical tools to develop their problem‐solving skills. Therefore, the approach of this project involved the development of a curriculum to train undergraduate food engineers in the effective use of computational fluid dynamics (CFD) software to solve food engineering problems by engaging them in the creation of food engineering teaching tools. These CFD outputs were then used as innovative teaching tools for the food science students. In this paper, this concept will be illustrated by unsteady‐state heat transfer and fluid flow problems. To evaluate the efficiency of the teaching materials developed, a student focus group was asked to answer the same quiz following a conventional and CFD output aided teaching session. The assessment result showed an improved understanding of the subject after the CFD teaching session. These visual aids were excellent tools to illustrate the validity of the formulas presented in class. In addition, the new visual materials enabled a better understanding of the relationships among different process parameters. In general, this helped the food science students better appreciate the food engineering concepts that govern food processing operations.  相似文献

For more than 2 years, Scratch programming has been taught in Taiwanese elementary schools. However, past studies have shown that it is difficult to find appropriate learning methods or tools to boost students’ Scratch programming performance. This inability to readily identify tutoring tools has become one of the primary challenges addressed in Scratch programming studies. To cope with this problem, we propose an innovative approach, which combines an Annotation‐based Scratch Programming (ASP) tool with the problem‐solving‐based teaching approach in Scratch programming pedagogy. The ASP tool was developed to enable students to create, review and share Scratch programming and homework annotations. In a quasi‐experimental study, we have evaluated Scratch programming pedagogy at a North Taiwanese elementary school to investigate the effects of instructional‐tools‐supported programming instructional modes on Scratch programming performance. The experimental results show that students who received ASP tool support in conjunction with a problem‐solving‐based teaching approach performed significantly better than the other groups. Based on our findings, the innovative approach was believed to play an important role in improving the learning patterns of younger pupils. Therefore, we suggest that teachers consider incorporating the innovative method into their teaching environments in order to boost students’ learning achievements in the area of Scratch programming and the subsequent learning process.  相似文献

A central premise of this article is that hypermedia tools may be developed for case and problem-centered learning in order to achieve significant learning outcomes such as deep conceptual understanding, conceptual change, and knowledge transfer. An approach for developing hypermedia case and problem-centered knowledge resources is proposed-the knowledge mediator framework (KMF)-which consists of design elements and learning activities that have specific sociocognitive theoretical and research rationales. A proof-of-concept study is then discussed; it involved high school students using a hypermedia system based on the main features of the KMF to learn neo-Darwinian evolutionary biology. Students using the experimental hypermedia system were found to change their evolutionary biology problem-solving models, and to continue to use expert-like models even 1 year after using the system. The use of the KMF to develop hypermedia learning materials in other domains and for constructive student projects is also considered. Overall, it is hoped that the framework and research outlined in this article may contribute to design and pedagogical principles for hypermedia learning tools that help students construct rich and useful understandings of challenging knowledge.  相似文献

The learning initiative described in this paper looks at how the adoption of a flexible, online learning approach can be used to optimize teaching and learning in engineering materials to a variety of engineering disciplines. The main driver for adopting this approach was to increase the effectiveness of delivery of subject matter. Practical examples are given of delivery strategies, activities and assessment protocols. This flexible, online approach required the development and implementation a learning management system for the provision of online lectures, audiovisual material, discovery-based learning activities and communication tools for the guidance of students in the self-management of their personal learning styles. The implementation of such an online initiative led to an encouraging response from both students and staff. This was seen as pivotal in its contribution to the success of the overall learning strategy.  相似文献

Students’ perceptions of their classroom climate have been found to relate significantly to students’ learning outcomes. The purpose of the present study was to construct an instrument for assessing elementary-school students’ perceptions of classroom climate, based on a previous instrument that was being used in Chile by a public national school mental health program as a tool for aiding teachers in improving classroom management, but which showed poor psychometric properties. We used a six-staged mixed-methods approach to construct relevant items and dimensions based on this measure and by adapting previously-existing scales. Item development included participatory construction of items involving program officials, focus groups with students, and a pilot study. The final version was administered to a sample of 6813 elementary-school students. Results showed adequate reliability and construct validity, convergent validity with school climate, and divergent validity with peer victimisation. When consequential validity was explored through semi-structured interviews with program officials and school administrators, we found that the instrument was being used as a tool for helping teachers to improve their school climate and management skills. We discuss the importance of constructing instruments using a mixed-methods approach.  相似文献

Climate change science is a challenging topic for student learning. This quantitative study examined the effectiveness of a geospatial curriculum approach to promote climate change science understandings in an urban school district with eighth-grade students and investigated whether teacher- and student-level factors accounted for students’ climate change knowledge achievement. The participants included 12 science teachers and 956 eighth-grade students. Data included a pre- and posttest climate change assessment measures for both teachers and students and a teacher measure of Geospatial Science-Technological Pedagogical Content Knowledge. Paired-sample t tests revealed statistically significant gains from pretest to posttest on their climate change knowledge (p < .001; effect sizes being large on multiple-choice items and medium on the open-ended response assessment). Both ordinary least squares (OLS) multiple regression and 2-level hierarchical linear modeling found that students’ initial climate change knowledge and gender were significant predictors for students’ posttest scores, p < .05. Students’ pretest scores were the strongest significant predictor of the posttest scores, p < .001. Neither the teachers’ climate change knowledge nor their Geospatial Science-Technological Pedagogical Content Knowledge had significant association with the students’ posttest scores. Teaching years was a significant predictor for students’ posttest scores in OLS regression (p < .001). The findings provide support that a geospatial curriculum approach is an effective science curriculum approach for learners in urban middle-level education.  相似文献

We evaluated influences on the climate change risk perceptions of undergraduate students in an introductory Earth Science course. For this sample, domain‐specific content knowledge about climate change was a significant predictor of students' risk perception of climate change while cultural worldviews (individualism, hierarchy) and political orientation were not. These results contrast with previous studies highlighting worldviews as a dominant influence on risk perception. At the beginning of the semester, students' climate change content knowledge was relatively low, with average scores on a 21‐item test less than 50%. Post instruction results indicated that students learned climate change science during the course, and their perceptions of risks associated with climate change increased. Unlike most prior research evaluating links between climate change knowledge and risk perception, our measure of content knowledge was a validated assessment specific to climate change. Use of this specific climate knowledge test may be one reason that we detected a relationship between climate knowledge and risk perception whereas most of the previous research has not. Another—possibly complementary—explanation may be a generational shift between our study sample and prior samples. Undergraduates today, having grown up with more exposure to climate change in schools and the media than previous generations, may be diverging from average adults in that learning climate science appears to also increase their perceptions of the risks climate change poses. Undergraduate courses with embedded climate‐related activities present an opportunity to both increase climate science knowledge and risk perceptions of future decision makers.  相似文献

A strong tradition of research in developed countries has established consistent relationships between students' outcomes and their perceptions of psychosocial characteristics of the classroom learning environment. The present research provides a replication of the prior work in developed countries by using samples of students from two developing countries, namely, Indonesia and Thailand. Indonesian versions of the individualized Classroom Environment Questionnaire and the Classroom Environment Scale were responded to by 373 students in 18 Grade 8 and 9 classes in Padang, whereas a Thai version of the Learning Environment Inventory was responded to by 989 students in 31 Grade 12 classes in Bangkok or nearby provinces. Results supported the predictive validity of student perceptions in that significant relationships emerged between student outcomes and classroom climate among students in both Indonesia and Thailand.  相似文献

This study aims to examine pedagogical formation students’ perceptions about Web 2.0 tools and educational practices. A case study approach forms the methodological framework of this study. This study was conducted with 42 pedagogical formation students of an Instructional Technology and Material Design course during the 2014–2015 spring semester. During the course, the students created digital materials such as puzzles, concept maps, worksheets, presentations and posters by using software including Prezi, Glogster, and Webspiration. Furthermore they were introduced to numerous Web 2.0 tools which were required learning for the purpose of the course. The data for this study was collected by the researcher through a questionnaire and open-ended questions developed in order to identify students’ views on Web 2.0 tools and educational practices they will face in their future professional life. Content analysis, frequency and percentage were used in the analysis of data. Answers to the following were sought from the data analysis: (1) which Web 2.0 tools do students use or planned to use in their current and future professional life (teaching profession); (2) what are the reasons students want to use Web 2.0 tools in their professional life as a teacher; (3) what are the views of students about their use of Web 2.0 tools in the educational context; and (4) what are students’ views about Web 3.0 technologies and the changes and innovations that will be brought about by these technologies in the field of education.  相似文献

Environmental issues such as climate change are becoming ever more important in today’s societies and politics. Information is spread by the media, for example, via the Internet or information brochures, employing different representational styles (e.g. sensational vs. neutral styles, emphasis of human vs. natural causes). We investigated the effects of such differences in presentation when informing about local impacts of climate change – more specifically about invasive species – on perceived risk, emotions, and learning. Seventy-two students at a German university read five brochures about the local effects of climate change and invasive species. They rated their perceived risk and emotions and worked on learning outcome tests. As expected, the sensational style led to higher perceived risk and stronger negative emotions than the neutral style. In addition, our results reveal a potential dilemma for environmental education: while a sensational style enhanced general learning outcomes, it seemed to lead to quite a negative and one-sided view about climate change and invasive species.  相似文献

ABSTRACT

In this article we explore the dynamic between the pedagogical and the urban, attending to ‘agentive urban learning’. By this we mean processes by which young people build agency in the urban context, in using the resources of the city to develop their own agency, and of developing agency to act within the city. By agency, we refer to the capacity to imagine and act to create individual and collective futures. Our interest is how young people develop such agentive urban learning themselves and how it might be enhanced pedagogically at school and university. Three case studies explore different facets—the first how young people themselves develop this agency in situated settings and the tools that they use to reflect upon the future; the second how digital tools might be used to enhance students’ understanding of the city as a site of change, in this instance, climate change; and the third how such agency might be developed collectively in partnership with other city dwellers. We conclude that a diversity of students’ engagement in urban contexts of learning offers ways from which to further investigate how identity, setting, and stakeholder relationships matter as part of potentially sustainable agentive learning futures.  相似文献

Hong Kong students enrolling in the tertiary sector exhibit tendencies to passivity and non-participation. There is also some evidence that, in common with other countries, the tertiary educational environment in Hong Kong may encourage the adoption of inappropriate approaches to learning. A programme was developed within the first year of a business studies degree with the purpose of enhancing students’ approach to learning. This was attempted by making them aware of different approaches, giving them the analytical tools to examine their own conceptions of and approaches to learning and by involving them in different forms of learning experience. Most students conceived ofieaming as a quantitative increase in knowledge. They exhibited similar patterns in respect of SPQ scores to other Hong Kong students, scoring slightly higher than their Australian peers with respect to “deep” and “achieving” approaches and slightly lower on the “surface” approach. Evaluation of the programme was based on a range of sources including unprompted views using the “slip” technique, course evaluation questionnaires and a second administration of the SPQ at the beginning of the students’ second year. The evaluation shows that student reaction to the programme was mixed, though with an overall balance in favour. The SPQ results showed.that although the mean scores for the “surface” approach rose and those for the “deep” and the “achieving” approach fell, they did so to a much lesser extent than on similar programmes.  相似文献

M-learning is gaining popularity in formal and informal education, both in developed and developing countries. Specifically it can be an effective tool to overcome digital divide in developing countries. The success of m-learning at tertiary level depends on the perception of students towards this form of learning. A scientific approach was used in this study to explore the critical factors responsible for m-learning adoption among university students. The findings of this study, based on 628 valid survey responses, have both theoretical and practical implications for researchers and policy-makers.  相似文献

Disruptive behaviours in classrooms pose a significant challenge for learning in schools and are, at the same time, a risk factor for students’ academic achievement and a major source for work-related stress among teachers. Earlier research suggests that clarifying the classroom rules and behavioural expectations, monitoring students’ adherence to them and using behaviour-specific praise are simple and effective practices to reduce disruptive behaviour. Most of the interventions have been developed for elementary schools, although behaviour problems tend to be more common in middle schools. This two-month pilot study using a pre–post design evaluated the effects of a class-wide intervention on learning climate and disruptive behaviour (evaluated by students and teachers); on teacher-experienced stress; and on the time needed to maintain the positive learning climate in middle school. The classes were nominated for the intervention by their teachers on the basis of poor learning climates. The intervention was based on clear behavioural expectations for the students, positive behaviour support and, if needed, rapid actions in response to high rates of disruptive behaviour. The intervention was carried out by teachers, supported by monthly counselling meetings. The results indicated a large reduction in disruptive behaviour, in the time needed to maintain positive learning climate and in strain experienced by teachers while teaching the classes. The intervention was highly accepted by teachers, principals and (although to lesser degree) students. Although the lack of a control group in the design limits conclusions regarding the amount of change attributable to the intervention, the results suggest that an easily applicable and trainable intervention, which requires very little external support, may produce significant improvements in learning climates in middle schools.  相似文献

Abstract

There is extensive evidence showing that the climate system is warming and human behavior is linked to the change. Despite increasing attempts to integrate climate change into school curricula, teachers have challenges in preparing and implementing climate change lessons. The study aims to look at (a) the kinds of wondering questions middle school students construct after they are engaged in a climate change activity called ‘It’s a Gassy World’ and (b) what teachers highlight in their reflections on these questions to improve their teaching. In this multi-case explorative study, the data comes from student artifacts, teachers’ written reflections, and semi-structured conversational interviews with teachers. A constant-comparative analysis of students’ wondering questions (N = 165) showed that the nature of the questions varies. These were grouped under three different categories: direct observation, interdisciplinary connections, and future projections questions. We then analyzed five teachers’ written reflections and interviews from a cultural historical activity theoretical perspective. This analysis revealed that teachers paid particular attention to certain tools (physical and conceptual), norms (epistemic and teaching), emotions, and division of labor routines in classrooms. We discuss how students’ wondering questions help teachers notice essential features of climate change learning such as spatiotemporal thinking.  相似文献

This work examines an innovative and evolving approach to facilitating teamwork learning in a generic first-year mechanical engineering course. Principles of inclusive, student-active and democratic pedagogy were utilised to engage students on both the social and personal planes. Learner opportunities to facilitate, direct and lead the learning direction were emphasised. This emphasis encouraged a rich learning process and motivated students dismissive of the need to examine their communication skills and those who initially perceived the topic as a personal intrusion. Through a sharing of curriculum decisions, a climate of trust, ownership and shared value arose. Students chose from a range of tools across personality-type indicators, learning style indicators and hierarchies of human needs, to assist their capacity to express and discuss engineering designs and concepts. Peer teaching and collaborative exercises were incorporated to provide an authentic learning context and to further the student's sense of ownership.  相似文献

Adult, professional students in a doctoral-level course used Web 2.0 tools such as wikis, blogs, and online discussions to develop answers to six “Big Questions” related to higher education finance and also produced a research paper that used original data or the research literature to improve understanding of a specific topic. At the close of the course, students were asked to provide examples of learning for each question and each tool, and to evaluate the tools used. Bloom's Digital Taxonomy was used to evaluate levels of learning. Results indicated that the level of learning mirrored that of the Big Question or was at higher levels when students used new tools. Wikis generated objections from students who did not care for group work, although others found it a good collaborative tool. Blogs were more acceptable, but online discussions were preferred because of the interaction and sharing among students. Research papers allowed students to learn material of their own interest and to do so in depth.  相似文献

In this study, a spreadsheet-based visualized Mindtool was developed for improving students’ learning performance when finding relationships between numerical variables by engaging them in reasoning and decision-making activities. To evaluate the effectiveness of the proposed approach, an experiment was conducted on the “phenomena of climate on earth” unit of an elementary school geography course. The experimental results showed that the spreadsheet-based visualized Mindtool significantly benefited the students in terms of improving their learning achievement and promoting their learning attitudes and satisfaction. Moreover, the cognitive load of the students was significantly decreased, indicating the effectiveness of this approach in helping students comprehend, learn content and organize their knowledge. To further investigate the learning behaviors of high-achievement and low-achievement students in using the spreadsheet-based Mindtool, a learning pattern analysis was conducted by coding the students’ behaviors recorded on video.  相似文献
