ABSTRACT This paper reports a survey of lecturers from six Turkish teacher education institutions. The study specifically aimed to investigate the fundamental issues, concerns, and challenges of implementing information technology (IT) in teacher education. The survey consisted of four sections. The first section of the survey comprised several aspects of IT familiarity, namely the use of twelve common IT applications. The second section investigated benefits of IT to lecturers and teachers seeking to reveal how teacher educators view the role of new instructional technologies for teaching and learning. The third section dealt with the factors which are vital to implementing IT in teacher education, and the final part drew attention to the issues affecting employment and retainment of competent lecturers in teacher education. Most lecturers had a rather positive image and enthusiasm towards the use of IT in teacher training, despite a lack of experience. Recommendations are made for future strategies in Turkey on the basis of this survey and the associated literature. 相似文献

The present study aims to identify first year Turkish Science undergraduates’ understandings and misconceptions of the concept
of light and its propagation. For this purpose, an instrument composed of four open-ended questions was developed by the researchers.
The diagnostic test was piloted with twenty students and modifications were made prior to the final administration of the
test. The content validity of the test questions was assessed by two physics researchers and one lecturer. These questions
were administered to a hundred first year undergraduates (aged 16–18) enrolled in the Science Teacher Training Department
in Ataturk University in Turkey. In addition, the semi-structured interviews of 30–40 min were conducted with the four students
whose responses involved common misunderstanding. All interview records were transcribed and analysed. The findings showed
that undergraduates’ understanding of light is poor and also they have important and prevalent misconceptions. Identified
misconceptions, some of which have been reported in the literature, are discussed qualitatively. The misunderstandings identified
were compared with those in the literature. The results have some implications for teaching light, suggesting that a substantial
revision of teaching strategies is needed.

The main aim of this study was to investigate the relationships between life satisfaction, gender, social security, and depressive symptoms of the Turkish elderly. This cross-sectional study included 216 (female = 127, male = 89) participants with ages ranging from 60 to 93 years (mean = 71.60 ± 7.39). Information Gathering Form and Life Satisfaction and Geriatric Depression Scales were used for data collection. It was determined that 42.1% of the elderly who participated in this study had high depressive symptoms scores. Life satisfaction (OR = 0.63, 95% CI = 0.53–0.71), lack of social security benefits (OR = 3.52, 95% CI = 1.25–9.89), and gender (OR = 2.53, 95% CI = 1.17–5.50) predicted the depressive symptoms significantly. The results of the study indicate that while depression risk increases, life satisfaction decreases. In addition, lack of social security benefits and being female also increase the risk of depression in the Turkish elderly. 相似文献

It is important for teachers of mathematics to know how pupils react to certain mathematical situations and what these reactions imply, in order to design more effective instructional environments based on their learning needs. This study reports the development processes of a digital learning tool (Learning Tool for Elementary School Teachers (L‐TEST)) that shows children's mathematical thinking for the ages of 4–11 years across certain problem situations. L‐TEST is designed as a support tool to be used in teacher education. A case‐based instructional model was used in designing the instructional tool. Video recordings were digitised to provide a rich environment where learners observe exemplary cases. These exemplified videos included children's mathematical development in the subjects of numbers and shapes, combined with discussions in line with the current research findings. Finally, a usability test for the learning tool was carried out. 相似文献

Oral language provides a foundation for reading comprehension. Story comprehension is a fundamental oral language skill; it covers making inferences, identifying main ideas, monitoring, perspective-taking, and applying working memory capacity. Complex reasoning and perspective-taking are key factors in deep reading comprehension. Preliterate children’s deeper story comprehension skills can be initial indicators of their later reading comprehension. Thus, the purpose of this research is to investigate preliterate preschool children’s story comprehension skills in detail. This study focuses on the additional multimedia features of digital storybooks and whether they hinder or promote young children’s explicit and implicit comprehension in a small group reading activity. The findings revealed that (a) children in the multimedia-enhanced storybook group outperformed the print storybook group in terms of both explicit and implicit story comprehension, (b) explicit story comprehension was higher than implicit story comprehension for both groups, and (c) the children recalled significantly more story elements and the length of the story retellings was greater with the aid of animated illustrations. The findings indicate that a digital storybook provides close temporal contiguity of text and visuals and may enhance story understanding by concretizing the narration. The study provides evidence that multimedia stories can foster children’s implicit story comprehension and inferential thinking about the content of the story. 相似文献

This research investigated the possible impacts of computers on Turkish fourth‐grade students’ geometry scores and further geometric learning. The study used a pretest–intervention–posttest experimental design. Results showed that students who did not have computers at home initially had lower geometry scores. However, these differences were minimised with an appropriate intervention containing computer‐based Tangram puzzles. This suggests that at schools, it seems more effective to integrate mathematical content and technology in a manner that enables students to do playful mathematical discoveries. 相似文献

The aim of this study was to evaluate the possible therapeutic or protective effects of Helichrysum plicatum DC. subsp. plicatum ethanol extract (HPE) against gentamicin-induced nephrotoxicity. Thirty-six Sprague Dawley male rats weighing between 200 and 250 g were used as live material. They were formed into six groups containing 6 rats each and were allowed to adapt to laboratory conditions for 7 d. Group I: control, 5% DMSO intraperitoneal (i.p.); Group II: HPE 100 mg/(kg·d) i.p.; Group III: HPE 200 mg/(kg·d) i.p.; Group IV: gentamicin as 80 mg/(kg·d) i.p.; Group V: gentamicin as 80 mg/(kg·d) i.p.+HPE 100 mg/(kg·d) i.p.; and Group VI: gentamicin as 80 mg/(kg·d) i.p.+HPE 200 mg/(kg·d) i.p. for 8 d. Following treatment, serum, liver, and kidney tissues were used to assess blood urea nitrogen (BUN), creatinine, enzymatic and non-enzymatic antioxidants, and lipid peroxidation. Gentamicin significantly increased serum BUN, creatinin, and liver and kidney levels of malondialdehyde (MDA). It also decreased the activity of catalase (CAT), glutathione peroxidase (GPx), and superoxide dismutase (SOD). Treatment with the HPE 100 mg/kg reversed gentamicin-induced alterations as evidenced by decreased serum BUN and creatinin, liver and kidney oxidant marker, and tubular necrosis as well as by an increase in antioxidant enzymes. It was found that HPE 200 mg/kg significantly increased liver and kidney tissue MDA levels in nephrotoxicity in rats. As a result, these findings support the proposition that HPE in 100 mg/kg dose demonstrates in the kidney and liver as free radicals and scavenger to prevent the toxic effects of gentamicin in both the biochemical and histopathology parameters. 相似文献
