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

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

This study investigated whether enrichment activities would improve achievement in science.

One hundred and eighty subjects took part in the study. They were assigned to two experimental, two control and one Hawthorne control groups. Experimental subjects participated in enrichment activities held outside the school. Control subjects were not given these activities while the Hawthorne control group was taken out on excursions unrelated to their science lessons.

The Cooperative Science Test (COST) was used to assess the acquisition of science concepts while science achievement was based mainly on school science examination scores.

The results indicated that the experimental subjects showed significantly greater improvement in concept attainment and science achievement. Correlations between science concept attainment and science examination scores were positive and significant.

The study concluded that participation in enrichment activities relevant to school science would improve science achievement.  相似文献

Since early 1974, a pilot project for integrated teacher training has been in progress at Oldenburg University. This is currently the only extensive teacher training reform which exist in the German Federal Republic.

All plans for this integrated training program are designed to provide training normally encompassed by the traditional two‐stage programm.

The integrated training program includes:

- studies in the areas of education and social science;

- studies in two major subjects which are later to be taught at school;

- practical studies and activities.

The new model leads to the following degrees:

- nine semesters of study for a Certificate of Qualification for primary and lower‐level secondary school;

- eleven semesters for a Certificate of Qualification for higher‐level secon dary school and the education of exceptional children.

Theoretic training in major subject areas and related didactic training as well as education and social studies take place chiefly in the form of projects. A basic assumption is that interdisciplinary projects which are practice‐ and problemoriented permit a highly desirable integration of theory and practice on the whole.

In the project, contact teachers are an essential link between field practice at school and academic training at the university. Contact teachers are under contact to the university for an extended period of time (generally three years). In place of remunation, their teaching loads are reduced by ten hours per week.

In 1978/79 the project will be put to the test as the first generation of students prepares for State Board Examinations.  相似文献

Background: This study is the second study of a design-based research, organised around four studies, that aims to improve student learning, teaching skills and teacher training concerning the design-based learning approach called Learning by Design (LBD).

Purpose: LBD uses the context of design challenges to learn, among other things, science. Previous research shows that this approach to subject integration is quite successful but provides little profit on (scientific) concept learning. For this, a lack of (knowledge of) proper teaching strategies is suggested as an important reason. This study explores these strategies and more specific the interaction with concept learning.

Sample: Six Dutch first-year bachelor’s degree science student teachers, between the ages of 16 and 18, and two science teacher trainers (principal investigators included) were involved.

Design and methods: A mixed methods study was used to study LBD’s teaching practice in depth. Based on a theoretical framework of (concept) learning-related teaching strategies video recordings of a guided LBD challenge were analysed to unravel teacher handling in detail. Complemented by questionnaire and interview data and students’ learning outcomes (pre- and post-exam) the effectiveness of teaching strategies was established and shortcomings were distracted.

Results: Students reached medium overall learning gains where the highest gains were strongly task-related. Teacher handling was dominated by providing feedback and stimulating collaboration and only 13% of all teacher interventions concerned direct explication of underlying science. And especially these explicit teaching strategies were highly appreciated by students to learn about science.

Conclusions: In accordance with insights about knowledge transfer, LBD needs to be enriched with explicit teaching strategies, interludes according to poor-related science content important for cohesive understanding and de- and recontextualisation of concepts for deeper understanding.  相似文献

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

A miracle has occurred in South Africa. A country bent on self‐destruction changed course over the past 5 years and achieved an extraordinary reconcilliation amongst its diverse people. The process of democratization and liberation has brought freedom to millions of South Africans previously governed by racial separation. The reconstruction and development of the nation is led by President Nelson Mandela.

Our youngest children have not been untouched by this. For the first time in our history there is a political commitment to serve young children and to provide resources for this.

Supported by intense research and investigation, and a sector deeply committed to improving conditions for young children, their families and communities, a comprehensive national policy and training framework for early childhood education and care has been developed.

This article begins by setting the context for early childhood education and care in South Africa. The article focuses on the principles which direct programme and service delivery, the development of a training framework, the role of lobbying and advocacy networks, strategies for improving the quality and increasing quantity of provision, and the role of non‐governmental organisations in service delivery.  相似文献

Purpose: In this paper, we discuss the role of participatory research in integrated agricultural technology development using the example of a solar fruit drying project in Mozambique.

Design/methodology/approach: We engage in seven participatory exercises with groups of farmers from two farmers’ associations in Inharrime district in Mozambique to identify their needs for solar fruit drying that are crucial for solar dryer technology design. We focus in the analysis on three of these exercises including a daily schedule exercise, SWOT (Strengths Weaknesses Opportunities and Threats) analysis and technology requirement exercise.

Findings: Participatory research takes a dual function for integrated agricultural technology development. First, it can help to identify the technology needs of farmers and second it can enable the exchange and creation of different sets of knowledge for agricultural technology development between multiple stakeholders.

Practical implications: Participatory research provides a tool for joint knowledge exchange and creation, which allows the identified technology requirements to be translated into practical technology design.

Theoretical implications: This paper extends the concept of integrated research to integrated agricultural technology development and shows how participatory research is a tool that enables transdisciplinarity, which presents the most desired form of integrated research.

Originality: This research is highly relevant for researchers working in an interdisciplinary environment with agricultural technology development in cross-cultural contexts. From a meta-level perspective, it provides insights for joint and integrated technology development.  相似文献

It is known that one of the major goals of preschool education, if not the most important one, is the socialisation of children. In kindergarten socialisation is mainly achieved through social studies activities.

There is worldwide research concerning the application of social studies to kindergarten. In Greece, specifically, there is no relevant data about this subject.

Therefore, the current study was carried out in order to find out, interalia, I) whether kindergarten teachers occupy students with social studies activities, 2) if they do occupy them, in what social studies activities children engage more frequently and 3) the self‐assessed adequacy of the kindergarten teachers’ training and their attitudes concerning the application of social studies activities to kindergarten.

In order to collect the necessary data for this study, three hundred kindergarten teachers, from urban and non‐urban areas of Greece, were given a questionnaire and the conclusions drawn from their answers form the basis of the study.

In order to gain greater data validity, the recorded answers were cross‐referenced with informal observations in classrooms of teachers who participated in the study.  相似文献

On defining distance education   总被引:1,自引:0,他引:1  
Four generally accepted definitions of distance education are analysed and from them six components of a comprehensive definition are chosen. The forms of education that are considered to fall within the concept of distance education as outlined are considered from the point of view of choice of medium, institutional type and didactic model. Various forms of education that bear some similarities to distance education but are not to be identified with it are described. The term ‘distance education’ is proposed as the most satisfactory solution to the problem of terminology.

The term ‘distance education’ covers the various forms of study at all levels which are not under the continuous, immediate supervision of tutors present with their students in lecture rooms or on the same premises, but which, nevertheless, benefit from the planning, guidance and tuition of a tutorial organisation.

(Holmberg,1977:9)

Distance education is education which either does not imply the physical presence of the teacher appointed to dispense it in the place where it is received or in which the teacher is present only on occasion or for selected tasks.

(Loi 71.556 du 12 juillet 1971)

Distance teaching/education (Fernunterricht) is a method of imparting knowledge, skills and attitudes which is rationalised by the application of division of labour and organisational principles as well as by the extensive use of technical media, especially for the purpose of reproducing high quality teaching material which makes it possible to instruct great numbers of students at the same time wherever they live. It is an industrialised form of teaching and learning.

(Peters, 1973:206)

Distance teaching may be defined as the family of instructional methods in which the teaching behaviours are executed apart from the learning behaviours, including those that in a contiguous situation would be performed in the learner's presence, so that communication between the teacher and the learner must be facilitated by print, electronic, mechanical or other devices.

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

Infantilism     
The aim of this article is to define and operationalize the construct of infantilism.

The methods of theoretical research involve analysis and synthesis. Age and content criteria are analyzed for childhood and adulthood. Infantile traits in an adult are described.

Results. The characteristics of adult infantilism in the modern world are defined, taking into account increasing information flows and socio-economic changes. The concept of “infantilism” and its main features are defined as an organization of the personality that includes traits and behavioral models that are typical of one's earlier age periods and not appropriate to the person's actual age, which is most articulately manifested in emotional and volitional immaturity of an individual.

Scientific novelty. The main psychological characteristics of adulthood are described, including reflection, the desire to work and have a vocation, vocational self-determination, work skills, the desire for self-realization, and emotional and volitional maturity. Objective characteristics of adulthood are: transition to economic and territorial independence of the parental family, and development of new social roles, such as that of worker, spouse, and parent. Two possible operationalizations of the concept are identified: objective (existence/absence in a person’s life of objective criteria of adulthood) and subjective (self-report on the subjective feeling of existence/absence of the psychological characteristics of adulthood).

The practical significance of the work consists in formulation of an operationalization of “infantilism,” which at the moment has so many interpretations. Such operationalization is necessary for further analysis and research.  相似文献

‘… Miss Caroline

tell me how you spend your time

I spend all my time

around the Singer machine…’

These lines from a popular song of the nineteen forties sum up what was for many women a new reality. This paper identifies the space at the sewing machine as mother's space and the sewing machine as an important element in the psychological and financial liberation of the woman, here the Caribbean woman of the twentieth century. Evidence in support of this claim is offered predominantly from Caribbean creative writing, where artists have noted the importance of that invention in the lives of their mothers and in the achievements of their families.  相似文献

Purpose: Through an analysis of a social farming (SF) case study, this article investigates how collaboration and knowledge co-creation between different actors can support the process of rural transition in order to stimulate innovation in the welfare system using agricultural resources.

Methodology: We used the ‘Antecedent-Process-Outcome Framework’ developed by Wood and Gray [1991. “Toward a Comprehensive Theory of Collaboration.” The Journal of Applied Behavioral Science 27 (2): 139-162] and adapted by Thomson and Perry [2006. “Collaboration Processes: Inside the Black Box.” Public Administration Review 66 (s1): 20-32], to analyse the collaborative process within the Board of Social Farming (BSF) in Valdera, Italy. The BSF in Valdera is particularly important as it was the first transition arena developed in Italy for SF development.

Findings: The article highlights the difficulties and opportunities encountered by the BSF in the knowledge co-creation and collaboration, and identifies key elements to facilitate innovation in SF and more generally in transition processes.

Practical implications: The article aims to generalize crucial practical elements in the relationship between collaborative approaches and innovation in the field of innovative welfare society, which is increasingly key to rural transition.

Theoretical implications: Innovation in SF is complex due to the need to identify new knowledge, diverse kinds of organizations and innovative interactions among many private and public stakeholders. The article explores the concept of collaboration in SF in order to re-define the production of public and private goods within local and rural communities.

Originality: The article aims to contribute to the ongoing discussion on the advantages and disadvantages of collaboration in order to reinforce rural transition pathways.  相似文献

Purpose: This study evaluates the impact of an outsourced extension service delivered by Lima Rural Development Foundation (Lima) in the Umzimkhulu district of South Africa. The evaluation is conducted at both the household and program levels.

Design/methodology/approach: Household impacts were estimated using two-stage regression with instrumental variables to account for selection bias. Gains in household income were extrapolated to estimate the net incremental benefit of the program and its financial return at district level. These analyses were underpinned by a rigorous sampling design.

Findings: The results show that the outsourced extension service made a significant and substantial contribution to household crop income and net income. In addition, clients perceived a range of socio-economic benefits such as better diets, improved product quality, and job creation. Analysis of the financial cost and benefit of the extension service at district level suggests an annual net incremental benefit of R5 million (US$0.4 million), and a 95% probability that returns to the service exceeded 20% in 2012/2013.

Practical implications: These results suggest that there is good reason for donors to continue funding effective extension services to small farmers in areas of high agricultural potential.

Theoretical implications: This is an empirical study. It uses well-established methods to measure the impact but introduces a local economy multiplier to capture some of the indirect effects of agricultural extension.

Originality/value: This research is valuable as very few studies worldwide have evaluated the impact of agricultural extension services at both the farm and program levels.  相似文献

This presentation looks at how young children learn basic geometrical concepts. Piaget's developmental levels will be examined to determine how they fit into the current research project. These will be compared with materials from the Soviet States that have recently become available from the NCTP in the USA.

The research project was constructed in a number of early childhood centres in a variety of socio‐economic areas. All of these centres had an early intervention program in operation so that special needs or ‘exceptional’ children could be observed along with mainstream children.

The researcher is investigating children's learning styles to determine the children's preferred learning styles when exploring spatial concepts. The question of whether exceptional children progress through the same stages and in the same order as the mainstream children is also being considered.

Spatial concepts in early childhood is an area that seems to have been neglected by researchers in favour of the development of number concepts. This research project aims to add to our knowledge of how young children learn spatial concepts.
