The paper considers aberrant behaviour in the context of cognitive style with reference to both diagnosis and treatment.

Aims.

The aims of the study were to investigate whether the style of pupils with behaviour problems was different from that of children with no reported problems, and also to consider how pupils of different style manifested their problem behaviours.

Sample.

The sample comprised 83 male pupils aged 10‐18 years from two residential special schools.

Method.

The sample were given the Cognitive Styles Analysis to assess their positions on the Wholist‐Analytic and Verbal‐Imagery style dimensions. The pupil records of the special school pupils who were at the extreme of the style dimensions were also examined.

Results.

When their style characteristics were contrasted with a Comparison Sample of 413 12‐16‐year‐old males attending 10 secondary schools, the special school pupils had a significantly higher proportion of both Wholists and Verbalisers, than the Comparison Group. Further, the inspection of the records indicated that the types of social behaviour and behaviour problems exhibited varied with style, and particularly on the Wholist‐Analytic dimension.

Conclusion.

The results were considered to have implications for the origins and treatment of problem behaviour.  相似文献

Background: One of the topics students have difficulties in understanding is electromagnetic induction. Active learning methods instead of traditional learning method may be able to help facilitate students’ understanding such topics more effectively.

Purpose: The study investigated the effectiveness of physical models and simulations on students’ understanding daily life applications of electromagnetic induction.

Sample: The nine participants in the study were voluntaries from the fourth year of the physics education undergraduate programme.

Design and methods: Lessons were designed to enhance students’ conceptual understanding of electromagnetic induction. Researchers developed multiple generator and simple electric motor models. These models and simulations about Faraday’s Law, magnetic field, magnets, generator and radio waves were used in lessons. The data were collected through open-ended questionnaire and semi-structured interview. Open-ended questionnaire was employed in a pre-test and a post-test. Students’ answers were categorized as sound understanding, partial understanding, misunderstanding and no understanding. At the end of the last lesson, the interview was implemented about the students’ opinions related to application.

Results: For each question, the number of responses matching the accepted scientific explanation increased after application. The number of illogical or incorrect responses decreased.

Conclusions: Physical models and simulations used in the present study had positive effect on students participated in this study to understand electromagnetic induction and its daily life applications.  相似文献

Background: Technological pedagogical content knowledge (TPACK) is critical for effective teaching with technology. However, generally science teacher education programs do not help pre-service teachers develop TPACK.

Purpose: The purpose of this study was to assess pre-service science teachers' TPACK over a semester-long Science Methods.

Sample: Twenty-seven pre-service science teachers took the course toward the end of their four-year teacher education program.

Design and method: The study employed the case study methodology. Lesson plans and microteaching observations were used as data collection tools. Technological Pedagogical Content Knowledge-based lesson plan assessment instrument (TPACK-LpAI) and Technological Pedagogical Content Knowledge Observation Protocol (TPACK-OP) were used to analyze data obtained from observations and lesson plans.

Results: The results showed that the TPACK-focused Science Methods course had an impact on pre-service teachers’ TPACK to varying degrees. Most importantly, the course helped teachers gain knowledge of effective usage of educational technology tools.

Conclusion: Teacher education programs should provide opportunities to pre-service teachers to develop their TPACK so that they can effectively integrate technology into their teaching.  相似文献

Background: A substantial review study of concept cartoons reports that few studies have indicated their functions. For this reason, the present study illuminates the extent to which concept cartoon-embedded worksheets (through constructivist context) accomplish these functions in conceptual learning.

Purpose: The purpose of the study is to determine the effect of the concept cartoon-embedded worksheets on grade 9 students’ conceptual understanding of Newton’s Laws of Motion.

Sample: Within a quasi-experimental research design with control group, the sample consisted of 102 grade 9 students (aged 15–16 years) enrolled in an Anatolian High School. They were randomly assigned to control (52 students) and experimental groups (50 students).

Design and methods: While the control group followed the existing physics instruction, the experimental one was exposed to the concept cartoon-embedded worksheets. To collect data, two scales (Newton’s Laws of Motion Test –NLMT– and Interview about Instances –IAI) were employed.

Results: The results indicated that the experimental group performed better than did the control group.

Conclusions: It can be deduced that the concept cartoon-embedded worksheets are effective in improving grade 9 students’ conceptual understanding and in replacing their alternative conceptions with scientific ones.  相似文献

Primary objective. To examine perceptions of academic quality and approaches to studying in students taking six technology courses by distance education.

Research design. Students taking four courses received an end-of-course questionnaire. The following year, students taking all six courses received a mid-course questionnaire.

Method. The Course Experience Questionnaire and the Revised Approaches to Studying Inventory were administered in a postal survey to 3539 students of the UK Open University.

Outcomes and results. Across successive levels of study, students were progressively less likely to adopt a deep approach, were more likely to adopt a surface approach and rated their courses less favourably, especially with regard to the workload and materials. Between the middle and end of a course, students were more likely to adopt a deep approach and gave more positive ratings with regard to the materials and amount of choice.

Conclusions. The survey instruments can be recommended as useful tools for monitoring the experiences of engineering and technology students.  相似文献

Background: Enhancing students’ metacognitive abilities will help to facilitate their understanding of science concepts.

Purpose: The study was designed to conduct and evaluate the effectiveness of a repertoire of interventions aimed at enhancing secondary school students’ metacognitive capabilities and their achievements in science.

Sample: A class of 35 Year 9 students participated in the study.

Design and methods: The study involved a pre-post design, conducted by the first author as part of the regular designated science programme in a class taught by him.

In order to enhance the students’ metacognitive capabilities, the first author employed clearly stated focused outcomes, engaging them in collaborative group work, reading scientific texts and using concept mapping techniques during classroom instruction. The data to evaluate the effectiveness of the metacognitive interventions were obtained from pre- and post-test results of two metacognitive questionnaires, the Metacognitive Support Questionnaire (MSpQ) and the Metacognitive Strategies Questionnaire (MStQ), and data from interviews. In addition, pre-test and post-test scores were used from a two-tier multiple-choice test on Light.

Results: The results showed gains in the MSpQ but not in the MStQ. However, the qualitative data from interviews suggested high metacognitive capabilities amongst the high- and average-achieving students at the end of the study. Students gains were also evident from the test scores in the Light test.

Conclusion: Although the quantitative data obtained from the Metacognitive Strategies Questionnaire did not show significant gains in the students’ metacognitive strategies, the qualitative data from interviews suggested positive perceptions of students’ metacognitive strategies amongst the high- and average-achieving students. Data from the Metacognitive Support Questionnaire showed that there were significant gains in the students’ perceptions of their metacognitive support implying that the majority of the students perceived that their learning environment was oriented towards the development of their metacognitive capabilities. The effect of the metacognitive interventions on students’ achievement in the Light test resulted in students displaying the correct declarative knowledge, but quite often they lacked the procedural knowledge by failing to explain their answers correctly.  相似文献

Purpose: The limited uptake of improved agricultural practices in Africa raise questions on the functionality of current agricultural research systems. Our purpose is to explore the capacity for local innovation within the research systems of Ethiopia, Malawi and Mozambique.

Design/methodology/approach: Using Conservation Agriculture (CA) as a case study, we qualitatively explore with 26 locally based agricultural researchers the context of CA research and promotion, including their perceptions on persistent research gaps and issues in closing them.

Findings: Respondents identified that CA was not yet a finished product, with concerns regarding the benefit, feasibility and relevance of CA implementation. They asserted that while further adaptation was required, they were unable to do this due to institutional constraints within their research, extension and policy contexts.

Practical implications: We find that CA continues to be considered a donor-driven intervention in its current form and requires substantial further adaptation to local contexts before researchers will deem it ready for farmer uptake. The five research gaps identified by respondents highlight practical areas where further adaptations must occur.

Theoretical implications: Our findings suggest a lack of participatory research and extension most likely reflects limited financial, human and social capital to implement more participatory approaches. Without addressing these capacities, widespread adoption of complex farming systems change appears unlikely.

Originality/Value: Whilst many studies have identified a need for local innovation to enable CA utilisation, few have qualitatively explored directly with local researchers the capacity of such systems to do so. We address this gap in the literature.  相似文献

Purpose: The key informants in a village setup were studied to understand the existing social and knowledge systems of farmers, their structure, and relationships between different actors. The purpose is to identify different channels of information and use them as a means to disseminate agricultural technologies and related information to farmers.

Design: We use the network map analysis in a case study approach as a tool to demonstrate the linkages between the key actors and stakeholders in the information network of farmers.

Findings: The government institutions are well networked among themselves but have limited interactions with non-government sources. Farmers in Bihar have strong linkages with few network actors, who are important nodes in the social knowledge network. The study showed heterogeneity and complexity in the network shape and structure across different districts.

Practical Implications: Knowledge networks and social networks are the drivers of information sharing and play a significant role in the diffusion of agricultural technology and related knowledge. Understanding these networks provides a platform for introducing the agricultural technologies and getting connected to a wider group of farming communities.

Theoretical Implications: The study shows that the network is formed by different actors and their role determine the nature and shape of the network. Knowledge of this heterogeneity is important in designing or revamping agricultural information systems.

Originality: Information and knowledge networks are least explored in the agricultural information dissemination process. Some studies have shown the role of actors and social networks, but this study uniquely explores and presents the heterogeneity of these networks.  相似文献

Purpose: The current paper aims at the classification of Greek agronomists/extensionists in adult education philosophical frameworks; the exploration of frameworks’ changes in the last 40 years; and the assessment of their relevance vis-à-vis the current developments.

Design/Methodology/Approach: The research addressed a purposive sample of 30 agronomists divided into two groups (older - younger). Questionnaire-based survey was followed by a semi-structured interview.

Findings: The views of both groups of agronomists follow the same orientation and revolve around the progressive and behaviourist philosophies. In terms of practice, the intervention of older agronomists mainly relates to the progressive, the liberal and the behaviourist philosophy while that of younger agronomists around the liberal framework; evidence shows a small turn of younger agronomists towards participatory extension.

Practical Implications: The current piece of work puts forward the gaps and weaknesses of Extension in Greece both in terms of rhetoric and practice; notably, Greek agronomists do not seem capable to support bottom-up processes.

Theoretical Implications: Research detected the espoused orientation of extensionists and the ways they assist their constituencies in practice.

Originality/Value: The work reported here is considered one means of raising the awareness of the field’s needs in documenting extensionists’ educational philosophies and how they guide practice.  相似文献

Purpose: To examine the factors that support and hinder farmers’ learning and to investigate the impact of an innovative learning program on farmers’ practice change.

Design/methodology/approach: Individual interviews and focus group discussions were held with 24 farmers over 20 months. Observations were made of these farmers as they participated with eight agricultural and social scientists in a range of innovative experiences to learn about chicory and plantain establishment and management. These learning experiences were designed around evidence-informed educational pedagogies. Data sets were analyzed using NVivo to determine common themes of affordances and barriers to learning and actual practice changes.

Findings: The affordances for learning and practice change include belonging to a learning community, enhancing self-efficacy, engaging with scientists, seeing relative advantage, reinforcing and validating learning, supporting system’s integration and developing an identity as learners. Barriers to learning and practice change include issues of: trialability, complexity, compatibility and risk.

Practical implications: The importance of basing new models of extension around evidence-informed pedagogies known through educational research to promote learning and practice change.

Theoretical implications: Sociocultural theory and self-efficacy theories of learning are critical to the success of effective agricultural extension programs.

Originality: To date, little empirical research about the affordances and barriers for pastoral farmers’ learning has been based on contemporary educational research.  相似文献

Purpose: This study uses data from a sample of 150 oilseed farming households from Arsi Robe, Ethiopia, to assess the impact of different knowledge bases (education, training and experience) and their interactions on linseed productivity.

Methodology: A multiple regression analysis was employed to assess the combined effect of the knowledge bases, factors such as age of the household head, land size, marketing channels and geophysical factors (such as land slope) on linseed productivity.

Findings: The findings reveal no differences in productivity between trained and untrained farmers. They further show that training and the interaction between training and experience positively influence productivity. Our findings, however, reveal farmer education to have an inverse yet insignificant effect on productivity. Furthermore, we found that factors such as the slope of the land and the choice of marketing channel also play an important role in influencing productivity.

Practical implications: Moving away from the traditional top-down approach could be the answer to avoid a mismatch between the information given by trainers and what the farmers actually need.

Theoretical implications: The study used interaction variables of knowledge bases, and attempted to demonstrate the importance of a tacit knowledge base, which is often not well documented and therefore neglected in research.

Originality/value: The research demonstrates the combined effects that interactions between several knowledge bases have on the productivity of linseed farmers.  相似文献

Background Global climate change (GCC) has become one of the most debated socio-scientific issues after an increase in media attention. Recently, there have also been several studies describing students’ and teachers’ alternative conceptions about GCC. Therefore, designing learning environments at the college level that focus on accurate conceptions of GCC has become important in order for pre-service teachers to correct their alternative conceptions. There are, however, a limited number of studies that aim to both increase pre-service teachers’ knowledge about these issues and explore their perceptions of teaching this subject.

Purpose The purpose of this study was to investigate the effects of inquiry-based activities on pre-service teachers’ knowledge about GCC and their perceptions of teaching this subject.

Sample The participants were 102 pre-service middle school mathematics and science teachers who were enrolled in an environmental education course.

Design and methods A one group pre-test–post-test design was employed to identify changes after pre-service teachers engaged in a learning unit on GCC. The inquiry-based GCC unit was implemented during the spring semester at a public university in northeastern Turkey. The unit was implemented over seven sessions. Data were collected through two questionnaires: the ‘GCC content questionnaire’ and the ‘perceptions of teaching GCC questionnaire’. Each questionnaire was administered both before and after implementation of the unit. Content questionnaire responses were analyzed using a paired-samples t-test. Responses to the perceptions of teaching questionnaire were analyzed using inductive open coding.

Results Results indicated that after the implementation the pre-service teachers significantly improved their understanding of GCC across all items in the content questionnaire, saw several benefits of and challenges about teaching GCC, and perceived themselves as better prepared to teach about GCC in their future classrooms.

Conclusions Teacher education programs should integrate inquiry-based GCC instruction to increase pre-service teachers’ knowledge as well as their preparedness to teach about this important planetary issue.  相似文献

Background: Researchers have indicated that assessment practices and methods should support learners’ construction of meaningful understanding of knowledge. Understanding students’ conceptions of assessment will enable us to construct more realistic, valid and fair assessments. Learners’ conceptualization of assessment would be imperative to serve as an essential reference to evaluate their learning progress.

Purpose: This study evaluated and compared the Singaporean and Taiwanese middle school students’ conceptions of science assessment. Within-country gender comparisons were also explored.

Sample: 424 Taiwanese and 333 Singaporean eighth graders were invited for a cross-country comparison.

Design and methods: The participants completed a questionnaire named Conceptions of Science Assessment.

Results: The findings showed that the summative assessment dominates in the Taiwanese classrooms, while formative and summative assessment are usually perceived in Singaporean classrooms. The Singaporean students had a greater tendency than their Taiwanese counterparts to perceive the purpose of assessment as a way of reproducing knowledge, and the formative assessment as improving learning, problem-solving, and critical judgment. No gender differences were found among either the Singaporean or the Taiwanese students.

Conclusions: Educators in both countries should provide learners with more opportunities to experience process-oriented science assessment activities and de-emphasize the usage of examination-oriented practices to achieve the sophistication of conceptions.  相似文献

The case is stated for a scheme of professional training for adult educators, which should at once be

_____ comprehensive and unified;

_____ able to take into account the particular possibilities of individual adult educators; and

_____ easily adjustable to the particular needs within the community.

Such a scheme can only be realized through the application of a modular structure. A scheme like this is being developed at Gwent College of Higher Education for a professional training programme which will give a Certificate in Continuing Education, conferring full teacher status in adult and further education. This development is used to illustrate the points the author wants to make. The development of a programme on such a scheme raises considerable structural and methodological problems, which are discussed and compared with what is done elsewhere.  相似文献

Background: One of the health indexes is living arrangement and nowadays has tended toward living alone which has terrible negative impacts on the elderly’s social health in Asia. About 62.2% of lonely older adults are afraid of falling. In addition, the activity level of them is much more limited.

Aim: The aim of this article is to compare loneliness, fear of falling, and quality of life in older women who live alone and live with others.

Methods: This cross-sectional study was done on 218 accessible elderly women (116 live alone, 102 live with others) to compare loneliness, fear of falling, and quality of life by using the Farsi versions of UCLA-LS, falls efficacy scale-international (FES-I), and SF12 questionnaires, respectively.

Results: Linear regression was used to compare the means of continuous outcomes between the two groups by adjustment on probable confounder’s age and falling history.

Conclusion: Fears of falling and physical aspect of life quality in the lonely older adults were considerably higher than other group.  相似文献
