Purpose: The objective of the present study was to compare the learning efficiency of two information and communications technology (ICT)-based instructional strategies (multimedia presentation (MP) and concept mapping) in a sample (n?=?187) of Greek sheep farmers operating mainly in Western Greece. Design/methodology/approach: In total, 15 instructional sessions have taken place. The knowledge assessment of the farmers, before and after the instructional interventions, was based on answers given to five questions of graded difficulty and the SOLO (Structure of Observed Learning Outcomes) taxonomy. Findings: The two instructional strategies showed comparable learning outcomes. Furthermore, prior participation to training sessions as well as the participants’ advanced education level enhanced the learning outcome. Practical implications: Simple applications of ICTs such as MPs and concept maps can be exploited in sheep farmers’ training. Special attention has to be paid to the content and the context of the digital learning material. Originality/value: The study contributes to the lack of evidence regarding the assessment of learning outcomes of instructional strategies assisted by digital learning environments in livestock farmers. 相似文献

The aims of our study were to compare the dominant (DOM) and non-dominant (NDOM) shoulders of high-level volleyball athletes and identify possible associations of shoulder adaptations with spike speed (SS) and shoulder pathology. A total of 22 male volleyball players from two teams participating in the first division of the Cypriot championship underwent clinical shoulder tests and simple measurements around their shoulder girdle joints bilaterally. SS was measured with the use of a sports speed radar. Compared with the NDOM side, the DOM scapula was more lateralised, the DOM dorsal capsule demonstrated greater laxity, the DOM dorsal muscles stretching ability was compromised, and the DOM pectoralis muscle was more lengthened. Players with present or past DOM shoulder pain demonstrated greater laxity in their DOM dorsal capsule, tightening of their DOM inferior capsule, and lower SS compared with those without shoulder pain. Dorsal capsule measurements bilaterally were significant predictors of SS. None of the shoulder measurements was associated with team roles or infraspinatus atrophy, while scapular lateralisation was more pronounced with increasing years of experience, and scapular antetilting was greater with increasing age. Adaptations of the DOM shoulder may be linked to pathology and performance. We describe simple shoulder measurements that may have the potential to predict chronic shoulder injury and become part of injury prevention programmes. Detailed biomechanical and large prospective studies are warranted to assess the validity of our findings and reach more definitive conclusions. 相似文献

The study assessed cognitive and academic performance of children demonstrating teacher-rated ADHD-related symptoms (Inattention [IA] and/or Hyperactivity/Impulsivity [H/I]) in a representative sample of, largely untreated, Greek elementary school students (N?=?923). A battery of tests assessing short-term memory (STM), sustained attention, executive functions (EFs), reading and math skills were administered. Significant deficits in EFs and STM were restricted to the groups of students displaying inattention symptoms and were only marginally elevated among students showing hyperactivity/impulsivity symptoms alone, in comparison to their non-symptomatic peers. A similar pattern of group differences was observed on tests assessing word- and text-level reading skills. Impaired performance on sustained attention tasks was less evident. Among students who manifested inattention symptoms, those who also showed impaired reading skills presented more severe EFs deficits than typically achieving students. Results demonstrated a close link between EFs, other than inhibition and set-shifting, everyday symptoms of inattention, and achievement in math and word-level reading skills. 相似文献

In this research we investigate whether the categorisation of physical quantities into intensive and extensive, according to scientific knowledge, is perceivable and understood by pupils aged 12–15 years. For this purpose we administered written questionnaires to 300 pupils, comprising four tasks for each intensive quantity: density and pressure. The tasks investigate whether pupils realise that intensive quantities do not depend on the amount of the system they refer to and the factors affecting pupils' reasoning and their consistency when studying phenomena involving fluids at rest or in transition. The analysis of responses led us to identify three models of consistent pupils' reasoning. It was also observed that a significant percentage of the pupils provide inconsistent answers, that is, they change their reasoning across tasks and use alternatives to scientific reasoning, influenced by phenomenological features of the tasks. According to our results we propose a number of recommendations, such as the introduction of intermediate teaching/learning steps to be followed as well as suitable experiments to be used towards the acquisition of the scientific model for density and pressure. 相似文献

This study explores children's attitudes toward individuals with special needs in Greece and in the United States. A total of 196 kindergarten‐age children participated in the study. Children's attitudes were examined using the Acceptance Scale for Kindergartners‐Revised (ASK‐R) and were further explored with the use of an open‐ended interview. In addition, the Inventory of Disability Representation (IDR) was used to collect information about how individuals with special needs are represented in school and classroom environments through books, displays, materials and curriculum. The results indicated that children in Greece and the United States were accepting of individuals with special needs. Also, children attending inclusive kindergartens held more positive attitudes when compared with children attending non‐inclusive kindergartens. Results from the interviews provided further information that contributes to the understanding of children's perceptions of people with special needs and the reasons why children become more or less favourably disposed towards individuals with special needs. Finally, IDR results indicated that the classrooms in Greece had low representations of individuals with special needs compared with US classrooms, which had moderate and high representations of individuals with disabilities in the classroom and school environments. 相似文献

In Greece, the development of the teaching of Information Technology (IT) in schools has been greatly influenced by the rapid development of technology, making IT literacy a priority for all individuals. Consequently, the teaching of algorithms and programming, with the ulterior motive of teaching modeling as well as problem solving, has been greatly limited in Secondary Education. However, we strongly believe that algorithms and programming constitute an important intellectual tool and should be included in basic education. In any case, both the research literature findings, as well as, our own experience confirm the fact that novice programmers come up against many mental obstacles in their attempts to understand the functioning of programs or the construction of algorithms. In order to deal with these difficulties and successfully teach the elementary concepts of algorithms and programming, we have developed didactic scenarios, which are based on specially designed educational software. In conjunction with this, we are attempting to develop a program for the systematic training of those students who will become IT teachers in Secondary or Primary Education. The most significant findings of our research are summarized as follows: (a) The development of educational software and its experimental use in the teaching process allow us to formulate several general rules related to the specific didactic characteristics, which these environments should include. (b) Educational software is effective only when it is incorporated within the framework of the didactic scenarios that the teacher organizes and which are supported by the software. (c) Teachers do not spontaneously use educational software in the context of this rationale. Therefore, specific training is required so that they adopt and use such software in didactic scenarios. 相似文献
