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.

Purpose: In this article the use of blended learning multimedia materials as an education tool was compared with the traditional approach for skills training.

Design/Methodology/Approach: This study was conducted in Ireland using a pre-test, post-test experimental design. All students were instructed on how to complete two skills using either a traditional or blended methodology. They were subsequently assessed to determine their ability to perform the practical skills.

Findings: The findings stressed the suitability of blended learning not only when it was found that there was no significant difference between method of teaching and skill acquisition but also when it was revealed that student demographics had no major influence on skill acquisition.

Practical Implications: It can be concluded that blended learning can be used effectively for the instruction of a diverse range of practical skills in agricultural college and benefit in the successful knowledge transfer to a growing and diverse student population with more emphasis placed on the students taking charge of their own learning environment.

Originality/Value: The article demonstrates the value of blended learning as a successful medium for practical skill attainment within the agricultural college environment.

There is evidence that phonological awareness skills secure decoding ability and that phonological deficits underlie failure to acquire adequate word recognition. Slow word‐reading rate may be an additional defining characteristic of reading disability. The present study aimed to investigate whether: (1) reading disabled (RD) Greek‐speaking children showed reading accuracy and reading speed deficits relative to chronological age‐matched controls (CAC) and reading age‐matched controls (RAC); (2) they showed phonological deficits relative to the two control groups who do not present reading difficulties; and (3) they showed reading comprehension deficits over and above any word reading deficits.

Results suggested that the reading accuracy of the RD group was predictably weaker than that of the CAC group but equivalent to that of the RAC group. However, the reading speed of the RD group was significantly slower than the RAC group, who showed the same single word reading speed as the CAC group.

Slow and laboured decoding was found to compromise the reading comprehension of the RD group, whose listening comprehension performance was as good as the two other groups. The RD children performed poorly on phonological awareness tasks and naming speed. Naming speed was not an independent core feature of reading difficulties in the Greek language but was associated with a general phonological deficit.

It is recommended that diagnostic assessments for children with reading difficulties in Greek should include phonological awareness, single word reading and pseudoword reading tasks that measure both accuracy and speed.  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

Ladd demonstrated the effectiveness of the social learning method for increasing social interactive behaviour of ‘mildly’ withdrawn/isolated children with their peers. The present study replicated Ladd's investigation with two important differences:

1. the subjects were ‘severely’ withdrawn/isolated children, and

2. the training sessions, unlike Ladd's fixed time schedule, continued until the subject's level of performance reached the level of ‘average’ peers in each targeted social skill.

The findings indicated that the social learning method increased social interaction of ‘severely’ withdrawn/isolated children with their peers. However increasing their rate of behaviour in targeted social skills to the level of performance of their ‘average’ peers required approximately four times as many sessions of training as Ladd conducted with ‘mildly’ withdrawn/isolated children.  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

During the late 1960s the United Kingdom was one of many countries which faced a potential educational crisis arising from a growing demand for post‐secondary education linked with inadequate resources for its conventional provision.

“Distance learning” techniques, providing an alternative form of study based on multi‐media methods outside formal educational systems, have emerged in response to this new demand.

Within the sector of higher education the Open University of the United Kingdom is one of the most comprehensive distance learning systems.

Many requests have been made to the University for information on distance education and for advice and assistance in establishing similar ventures elsewhere. In response to these developments the University Senate has created recently a Centre for International Co‐operation and Services (CICS).

We give below information on the main functions of this Centre within the framework of the Open University activities.  相似文献

Purpose: This paper presents economic and pedagogical motivations for adopting information and communications technology (ICT)-mediated learning networks in agricultural education and extension. It proposes a framework for networked learning in agricultural extension and contributes a theoretical and case-based rationale for adopting the networked learning paradigm.

Design/methodology/approach: A review of the literature highlights the economic and pedagogical need for adopting a networked learning approach. Two examples are described to instantiate the language for learning networks: a small community of farmers in India and large Twitter community of Australian farmers.

Findings: This paper reviews evidence that successful networked learning interventions are already occurring within agricultural extension. It provides a framework for describing these interventions and for helping future designers of learning networks in agricultural extension.

Practical implication: Facilitation of learning networks can serve to achieve efficient agricultural extension that connects farmers across distances for constructivist learning. To realize these benefits, designers of learning networks need to consider set design, social design and epistemic design.

Theoretical implication: This paper contributes a theoretical framework for designing, implementing and analysing learning networks in agriculture. It does this by integrating existing ideas from networked learning and applying them to the agricultural context through examples.

Originality/value: This paper contributes an understanding of the value of networked learning for extension in terms of economic and pedagogical benefits. It provides a language for talking about learning networks that is useful for future researchers and for practitioners.  相似文献

Background: Even infants can recognize whether patterns of motion are or are not natural, yet an acknowledged challenge for science education is to promote adequate reasoning about such patterns. Since research indicates linkage between the conceptual bases of recognition and reasoning, it seems possible that recognition can be engaged to support reasoning.

Purpose: Noting the theoretical and practical significance of showing that recognition can support reasoning, the reported research aimed to examine the possibility in relation to horizontal motion.

Sample: The research was conducted with 167 children (mean age = 9.51 years) from Years 4, 5 and 6 of an English-medium school located in Lisbon, Portugal.

Design and methods: Individual pre-tests were administered to all participants to assess initial reasoning about the direction and speed with which rolling balls travel after collision. Reasoning was assessed in the sense of both predicting and explaining. Thereafter, about two-thirds of the sample worked with software that, via simulations of the incorrect patterns that were typically predicted (and comparison with simulations of correct patterns), engaged recognition as feedback on reasoning. The remaining children became an untutored control group. Replicating characteristic computer use in classrooms, half of the software sample worked as singletons with adult guidance available on request and half worked in pairs without the option of guidance. A few weeks later, all participants were post-tested following pre-test procedures.

Results: Pre- to post-test change amongst the children who worked with the software exceeded pre- to post-test change within the control group, and this was observed with both predictions and explanations. The differences were strongest amongst the children who worked as singletons, even though they seldom requested adult support.

Conclusions: Although issues remain to be addressed before the approach can be optimized, its viability as support for reasoning has been demonstrated, and this may have relevance beyond horizontal motion.  相似文献

Background: Microorganisms are very important in day-to-day life, but they are inadequately addressed in the Spanish educational system. It is essential that students are well informed about their characteristics and functions.

Purpose: The study aims to find out primary school students’ perceptions of microorganisms and to analyze whether theoretical or practical teaching interventions produce different levels in student’s learning about this topic.

Sample: The sample consisted of 199 primary students in 2nd (aged 7–8) and 6th (11–12) grades from two public schools in Albacete (Spain).

Design and method: This study uses a pre- and post-intervention questionnaire to evaluate the knowledge of students on the issue of microorganisms. We compare differences by age and two teaching–learning intervention methodologies: theoretical and practical.

Results: Results from the pre-test showed a poor understanding and several misconceptions. Children have a limited and negative view of microorganisms, mainly derived from non-formal learning. Both types of intervention provided an improvement in knowledge, but closed questions did not reveal clear statistically significant differences between methods. Open questions showed how the scientific use of the language and quality of verbalization is much better in the groups that received a practical intervention.

Conclusion: The findings can be a starting point for curriculum planners and for teachers interested in engaging students in science learning.  相似文献

Ongoing work in Andhra Pradesh Primary Education Project (APPEP) (Southern India) has resulted in the production of a new Class 1 textbook, teacher textbook and eight supplementary readers. These important and innovative new classroom materials have been produced as a result of training and workshops involving resource persons from the Telugu Academy, Telugu University, State Centre for Educational Research and Training and lecturers in District Institutes of Education and Training. Additionally, for the first time, primary school teachers were co‐opted on an equal basis to work on the materials.

The textbook, which constitutes the only learning material in Class One, is designed to teach children to read and write in Telugu. Previous research showed that children at the end of Class 2 were mostly unable to identify letters or words out of the context and order in which they appeared in the textbook. The current state textbook was basically a writing primer, teaching writing in alphabetic order with reading rarely going beyond single words or sentences.

The new textbook incorporates the necessary ‘reading context’ using rhymes, short stories and dialogue to encourage shared reading with the teacher before individual letters are learned. The order of introduction of the letters for writing has been based on research showing generalisable shapes in letters; alphabetic order is learned as a separate item. The pictures in the book were designed to promote discussion and develop prediction and an understanding of story structure. The content was matched to the child's developmental and psychological needs.

The teacher textbook incorporates ideas for extending learning into activities and exercises and consists of the children's textbook interleaved with teacher guidance. The evaluation shows that this teacher guidance has been used and valued by the teachers.

The eight supplementary readers are at four levels. Level One is for shared reading with the teacher and includes folk stories, songs and a story about a family. Level Two are picture books with simple captions and sentences using only the letters and words already learned by the child. Level Three progresses to more extensive stories including some information based stories. Level Four revisits Level One for independent reading of the same books.

The books have been trialled in 50 sample schools matched on a number of variables to 50 control schools. A pre‐reading test was administered to all children and a post‐reading test measured learning gains. Case studies of the books in use in classrooms were also undertaken. The evaluation to date shows significant learning gains amongst the children in the sample schools, a high degree of teacher satisfaction and interest and approval from parents and children. A resource team including teachers has been trained for further renewal of textbooks throughout the primary years.

This work has been funded by the Overseas Development Administration and they will fund the provision of eight supplementary readers in all Class One in schools throughout the state in 1996. After revision the textbook will be implemented by the Government of Andhra Pradesh.  相似文献

Background: The development of primary pre-service teachers’ chemistry motivation and attitudes toward chemistry were examined in order to develop their science literacy using case-based learning. Students’ ideas were emphasized, real-life situations were discussed, and students could share their ideas and knowledge with peers; as a result, students were active in the learning process.

Purpose: The purpose of the study was to investigate the effectiveness of using case-based learning instruction to increase pre-service primary teachers’ chemistry motivation and improve their attitudes toward chemistry as a school subject.

Sample: The subjects of this study consisted of 51 (20 female, 31 male) freshman primary pre-service teachers from an urban university in Turkey. The mean age of the primary pre-service teachers was 21.

Design and methods: One group pre-test and post-test design was used. A chemistry motivation questionnaire and chemistry attitude scale were used for data collection. For the data analysis, two-way repeated measures of ANOVA and repeated measures MANOVA were conducted.

Results: The results indicated that the mean of the attitude score after the treatment was significantly greater than the mean of the attitude before the treatment. The results also demonstrated that there is no significant difference between females and males. According to the results of the study, there is no significant difference between primary pre-service teachers’ chemistry motivation. However, some chemistry motivation constructs mean scores are greater after the treatment.

Conclusions: In sum, it could be stated that case-based learning is helpful for the development of students’ chemistry motivation and attitudes toward chemistry.  相似文献

Background: Complexity models have provided a suitable framework in various domains to assess students’ educational achievement. Complexity is often used as the analytical focus when regarding learning outcomes, i.e. when analyzing written tests or problem-centered interviews. Numerous studies reveal negative correlations between the complexity of a task and the probability of a student solving it.

Purpose: Thus far, few detailed investigations explore the importance of complexity in actual classroom lessons. Moreover, the few efforts made so far revealed inconsistencies. Hence, the present study sheds light on the influence the complexity of students’ and teachers’ class contributions have on students’ learning outcomes.

Sample: Videos of 10 German 8th grade physics courses covering three consecutive lessons on two topics each (electricity, mechanics) have been analyzed. The sample includes 10 teachers and 290 students.

Design and methods: Students’ and teachers’ verbal contributions were coded manual-based according to the level of complexity. Additionally, pre-post testing of knowledge in electricity and mechanics was applied to assess the students’ learning gain. ANOVA analysis was used to characterize the influence of the complexity on the learning gain.

Results: Results indicate that the mean level of complexity in classroom contributions explains a large portion of variance in post-test results on class level. Despite this overarching trend, taking classroom activities into account as well reveals even more fine-grained patterns, leading to more specific relations between the complexity in the classroom and students’ achievement.

Conclusions: In conclusion, we argue for more reflected teaching approaches intended to gradually increase class complexity to foster students’ level of competency.  相似文献

Background: Recently, there is a growing interest in independent learning approaches globally. This is, at least in part, due to an increased demand for so-called ‘21st century skills’ and the potential of independent learning to improve student skills to better prepare them for the future.

Purpose: This paper reports a study that explored the effectiveness of two different independent learning approaches: (i) guided independent learning and (ii) unguided independent learning with independent research, in enabling students in an undergraduate Macromolecules course to acquire knowledge in one chemistry context and apply it successfully in another.

Sample: The study involved 144 chemistry students commencing their first term of undergraduate study at a northern university in England. Students completed pre- and post-intervention tests containing 10 diagnostic questions, of which 4 measured students’ knowledge acquisition in one context and 6 measured their ability to apply it in another.

Design and methods: Diagnostic questions had been identified using a Delphi approach. Paired t-tests and chi-square tests were used to analyse the significance of any change in students’ responses to the diagnostic questions and the number of responses evidencing misconceptions, respectively.

Results: Whilst guided independent learning settings were found to improve students’ knowledge and ability to apply that knowledge in novel situations, unguided independent learning had no statistically significant effect. Unguided independent learning was also linked to a statistically significant increase in the number of student misconceptions in one of the diagnostic questions.

Conclusions: The results of this study show that guidance in independent learning activities is a key necessity for effective learning in higher education. This paper has strong relevance and high significance to tertiary STEM education, especially in the light of increased importance of teaching, such as the Teaching Excellence Framework in the UK, and shifts to more independent learning activities.  相似文献

Background: The sophistication of students’ conceptions of science learning has been found to be positively related to their approaches to and outcomes for science learning. Little research has been conducted to particularly investigate students’ conceptions of science learning by laboratory.

Purpose: The purpose of this research, consisting of two studies, was to explore Taiwanese university science-major students’ conceptions of learning science by laboratory (CLSL).

Sample: In Study I, interview data were gathered from 47 university science-major students. In Study II, 287 university science-major students’ responses to a CLSL survey were collected.

Design and methods: In Study I, the interview data were analyzed using the phenomenographic method. Based on the findings derived from Study I, Study II developed an instrument for assessing students’ CLSL by exploratory factor analysis.

Results: Study I revealed six categories of CLSL, including memorizing, verifying, acquiring manipulative skills, obtaining authentic experience, reviewing prior learning profiles, and achieving in-depth understanding. The factor analysis in Study II revealed that the ‘verifying’ category was eliminated, but found another new category of ‘examining prior knowledge.’

Conclusions: This study finally proposes a framework to describe the variations of CLSL, consisting of three features: cognitive orientation, metacognitive orientation, and epistemic orientation. Possible factors influencing students’ CLSL are also discussed.  相似文献

This study compared 13 high (mean = 132.5) and 13 above average IQ (mean = 111.8) children aged 44 to 63 months on a spatial perspective taking task. The high group made significantly fewer egocentric errors and more correct responses. This may be a useful indication of high ability from an early age. All subjects made a relatively large number of adjacent errors, selecting a perspective between one's own and another viewer's, but the total score was uncorrelated with egocentric errors. Adjacent errors may provide more clues than egocentric errors to understanding the specific skills that need to be learned to overcome egocentrism, notably distinguishing the common features shared by the viewers in addition to recognizing the view of each. Possible relations to metacognition and flexibility are discussed. The results warrant continued exploration of perspective taking and its relationship to the development of thinking.

Subjectivity is one of the elemental human needs. It is also significant since it plays a part in educational situations. A particularly important premise of subjectivity is responsibility for one's actions and, associated with this, determination of a direction for one's own activity, the exercise of control and the making of choices.

Human activity takes place principally in a social context. For this reason it is important to pay attention to two‐subject relationships. Their features are above all purposefulness, bi‐directionality and co‐ordination. Two‐subject activity may be of two sorts—negative co‐operation (conflict) or positive co‐operation, co‐ordination of a line of action including dialogue and collaboration.

Educational activity, particularly when directed at younger children, is characterized by different planes of functioning. The adult acts in a longer‐term perspective and formulates his aims in terms of general concepts but a small child acts in a short term perspective and formulates aims in concrete terms.

A system of priorities is put forward here, a two‐task model for the educational situation which makes subjective activity possible both for the child and for the adult. In the last part of the article an experiment is described which illustrates how such a two‐task situation works with a system of priorities and the results that were obtained.

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: Inquiry learning in science provides authentic and relevant contexts in which students can create knowledge to solve problems, make decisions and find solutions to issues in today’s world. The use of electronic networks can facilitate this interaction, dialogue and sharing, and adds a new dimension to classroom pedagogy.

Purpose: This is a report of teacher and student reflections on some of the tensions, reconciliations and feelings they experienced as they worked together to engage in inquiry learning. The study sought to find out how networked ICT use might offer new and different ways for students to engage with, explore and communicate science ideas within inquiry.

Sample: This project developed case studies with 6 science teachers of year 9 and 10 students, with an average age of 13 and 14 years in three New Zealand high schools. Teacher participants in the project had varying levels of understanding and experience with inquiry learning in science. Teacher knowledge and experience with ICT were equally diverse.

Design and Methods: Teachers and researchers developed initially in a joint workshop a shared understanding of inquiry, and how this could be enacted. During implementation, the researchers observed the inquiry projects in the classrooms and then, together with the teachers, reviewed and analysed the data that had been collected.

Results: At the beginning of the project, some of the teachers and students were tentative: inquiry based teaching supported by ICT meant initially that the teachers were hesitant in letting go some of the control they felt they had over students learning, and the students felt insecure in adopting some responsibility for their own learning. Over time a sense of trust and ease developed and this ‘control of learning’ balance moved from what was traditionally accepted, but not without modifications and reservations.

Conclusions: There is no clear pathway to follow in moving towards ICT-supported science inquiry in secondary schools. The experience of the teacher, the funds of knowledge the students bring to the classroom, the level of technological availability in the school and the ability of the students are all variables which determine the nature of the experience.  相似文献
