The present study aimed to evaluate whether a chemistry laboratory course called “Laboratory Experiments in Science Education” based on constructivist instruction accompanied with concept mapping enhanced pre-service chemistry teachers’ conceptual understanding. Data were collected from five pre-service chemistry teachers at a university in Ankara by means of a concept test and semi-structured interviews. Results showed that pre-service teachers had some alternative conceptions about chemistry topics. Moreover, using constructivist instruction accompanied with concept maps as an instructional tool was effective to promote conceptual understanding. Participants thought that concept maps were useful especially in recognizing the relation between different chemistry concepts.  相似文献   

The impact of electronic communication technology on written language     

Mohd. Sahandri Gani B. Hamzah Mohd. Reza Ghorbani Saifuddin Kumar B. Abdullah 《美中教育评论》2009,6(11):75-79

Communication technology is changing things. Language is no exception. Some language researchers argue that language is deteriorating due to increased use in electronic communication. The present paper investigated 100 randomly selected electronic mails （e-mails） and 50 short messaging system （SMS） messages of a representative sample of international students in University Putra Malaysia （UPM） to find out the impact of these two specific modes of electronic communication on written language use. The e-mails from UPM International Students Association （UPM-ISA） yahoo group were content analyzed. A non-probability convenience sampling was used to select the 50 short message services sent to the researcher about different subject matters by Malaysian and international students at UPM. Then, they were also content analyzed. The results indicated that the language used in students＇ e-mails and SMS messaging was full of spoken-like spelling, unconventional use of punctuation and abbreviations, and ungrammatical sentences. However, the more in-depth content analysis of the data revealed that the written language is being creatively adapted, developed, and enhanced to suit the conditions of the electronic communication age. Syntactical and lexical reductions are just strategies used to reduce effort, time and space.  相似文献   

Teacher self‐regulation: examining a multidimensional construct     

Yesim Capa‐Aydin  Semra Sungur  Esen Uzuntiryaki 《教育心理学》2009,29(3):345-356

This study aimed to develop and validate an instrument to assess the multidimensional nature of teacher self‐regulation. A nine‐factor structure was proposed: goal setting, intrinsic interest, performance goal orientation, mastery goal orientation, self‐instruction, emotional control, self‐evaluation, self‐reaction, and help‐seeking. Through a series of confirmatory factor analyses with different samples, this nine‐factor structure was supported. Reliability estimates were also satisfactory. Further validation evidence was provided through canonical correlation analysis between teacher self‐regulation and teachers’ sense of efficacy. Results indicated that the Teacher Self‐Regulation Scale can be utilised as a valid and reliable instrument to assess teachers’ self‐regulatory strategies.  相似文献   

EFL Writers' Attitudes and Perceptions toward F-Portfolio Use     

Selami Aydin 《TechTrends》2014,58(2):59-77

Atitudes toward and perceptions of using Facebook as a portfolio-keeping tool in teaching English as a foreign language (EFL) writing. In general, existing research reveals primarily positive effects of Facebook on educational activities, and research on portfolio keeping in EFL writing shows both benefits and problem areas. Thus, the current study aims to investigate EFL writers’ attitudes toward using Facebook as a portfolio (F-Portfolio) tool and their perceptions regarding its benefits and problems. The sample group consisted of 101 EFL learners. A portfolio attitude scale, portfolio contribution questionnaire and a portfolio problem questionnaire were used to collect data. Four results were obtained from the study: (1) EFL writers have positive attitudes toward the use of F-Portfolios in EFL writing; (2) F-Portfolios improve EFL learNo results have been reported regarding at- ners’ knowledge of vocabulary and grammar, as well as their research, reading and writing skills; (3) EFL learners perceive some problems during the F-Portfolio process; and (4) some independent variables are significantly correlated with a limited number of items in the scales.  相似文献   

Implications of distance education on children with disabilities     

Mustafa Karnas  Beyza Alpaydın  Abdullah Eker 《Support for Learning》2023,38(2):98-118

Once the COVID-19 was announced as a pandemic by the World Health Organization at the beginning of 2020, almost all countries around the world shifted from traditional face to face education to distance education to prevent the spread of the virus. Türkiye implemented distance education practices through a web-based platform named education information network (EBA) and EBA TV channels. However, the rapid shift from traditional face to face education to distance education was challenging especially for students with disabilities, their parents and teachers because these students needed individualised education and some services which were impossible to implement remotely. The purpose of this study was to explore (a) the challenges that teachers and students faced during distance education; (b) the implications of distance education on students with disabilities. Further, this study explored opinions of special education teachers regarding how to make distance education more effective for students with disabilities. A semi-structured interview was conducted with 12 special education teachers. Findings demonstrated that distance education through EBA was neither sufficient nor convenient for most students with disabilities. Limitations of this study and suggestions for future research were discussed.  相似文献   

Interplay of motivational and cognitive strategies in predicting self‐efficacy and anxiety     

Yes¸im Çapa Aydin  Esen Uzuntiryaki  Betül Demirdögˇen 《教育心理学》2011,31(1):55-66

The purpose of the present study was to test a model explaining self‐efficacy and anxiety by the interrelationships with task value, cognitive strategies (rehearsal, elaboration and organisation) and metacognitive self‐regulation in the domain of chemistry. Data were collected from 518 college students in Turkey. Findings of structural equation modelling indicated that chemistry self‐efficacy and anxiety were predicted as a function of task value, cognitive strategies and metacognitive self‐regulation, supporting the proposed model. That is, students with high levels of task value tended to use more learning strategies which promoted the use of regulatory strategies. In turn, these students may decrease their chemistry anxiety, leading to an increase in chemistry self‐efficacy indirectly.  相似文献   

The impact of the pandemic on early career researchers' work-life and scholarly communications: A quantitative aerial analysis

After two-years of repeat interviewing early career sciences/social sciences researchers from around the world about their work life and scholarly communications in pandemic-times, the Harbingers-2 project is in a position to release quantitative data on the pandemic's overall impact. The data comes from around 50 questions asked in the third and final round of interviews with 147 early career researchers (ECRs), which had a codifiable element to them (such as yes, no, do not know). The 19 scholarly topics covered include: pandemic-related research; research funding; changes to the workplace/working from home; pandemic-incurred stress and anxiety; teaching; employment security; career progression; mentoring; assessment (including metrics); collaboration; searching/finding information; ethics; networking; informal communication; publishing; sharing; pre-prints; outreach; and scholarly transformations. The main findings are that in six broad aspects of ECRs' work-life and scholarly behaviour, more than 50% of ECRs were impacted by the pandemic, with remote teaching having the greatest impact. By way of comparison, in another six aspects there was little change, least of all when it came to sharing activities. Among the countries studied, Malaysia stood out as being the most impacted, and of the disciplines it was the medical sciences and the soft social sciences most impacted.  相似文献   

Total thyroidectomy is safer with identification of recurrent laryngeal nerve     

Canbaz H  Dirlik M  Colak T  Ocal K  Akca T  Bilgin O  Tasdelen B  Aydin S 《Journal of Zhejiang University. Science. B》2008,9(6):482-488

Objective: To investigate the effect of recurrent laryngeal nerve (RLN) identification on the complications after total thyroidectomy and lobectomy. Methods: Total 134 consecutive patients undergoing total thyroidectomy or thyroid lobectomy from January 2003 to November 2004 were investigated retrospectively. Patients were divided into two groups: RLN identified (Group A) or not (Group B). The two groups were compared for RLN injury and hypocalcaemia. Results: The numbers of patients and nerves at risk were 71 and 129 in Group A, and 63 and 121 in Group B, respectively. RLN injury in Group A (0) was significantly lower than that in Group B (5[7.9%]) patients, 7 [5.8%] nerves) for the numbers of patients (P=-0.016) and nerves at risk (P=0.006). Temporary hypocalcaemia was significantly higher in Group A than in Group B (14 [24.1%] vs 6 [10.3%], P=0.049).Permanent complications in Group B were significantly higher than those in Group A (13 [20.6%] vs 4 [5.6%], P=0.009). Conclusion: RLN injury was prevented and permanent complications were decreased by identifying the whole course and branches of the recurrent laryngeal nerve during total thyroidectomy.  相似文献   

The ability of children to generalize selected science concepts     

Kemal Bin Abdullah  Walter E. Lowell 《科学教学研究杂志》1981,18(6):547-555

The study investigated the ability of primary and elementary school subjects to generalize two science concepts, Insect and Animal with and without instruction in the form of a mental set. It also examined the effects of age, IQ, and sex on the ability of the children to generalize these concepts. Two instruments measuring the ability to generalize the concepts Insect and Animal were developed. The results indicate that of the independent variables investigated, age and mental set significantly affected the ability to generalize the concepts Insect and Animal. It was found that the younger children's concepts were least developed and with age these concepts became more developed and more conceptual in nature. The ability to use information given in a mental set was found to be a function of age. The children in this study were more able to generalize the concept Insect than the concept Animal. The results suggest that children with age and instruction axe better able to master less general concepts than more geaeral ones. In addition, the study demonstrated that children are able to improve their learning of general concepts provided a great number and variety of instances and noninstances of the concept are used in the instruction. It was also found that the younger children were more perceptually bound than the older children. The younger children were unable to overcome the pull of perceptual attractiveness that the noninstances held for them despite instruction. The results suggest that teachers of such children should be aware of the conceptual level of the content being taught to such children to ensure appropriate and meaningful learning takes place.  相似文献   

Sci‐Hub: The new and ultimate disruptor? View from the front     

David Nicholas  Chrifa Boukacem‐Zeghmouri  Jie Xu  Eti Herman  David Clark  Abdullah Abrizah  Blanca Rodríguez‐Bravo  Marzena wigo&#x; 《Learned Publishing》2019,32(2):147-153

The Harbinger project was a 3‐year‐long international study of the changing attitudes and behaviours of early career researchers (ECRs). One of the aims of the project was to discover if ECRs were adopting disrupting platforms that, legitimately or illegitimately, promote openness and sharing. It has been alleged that such an adoption appeals to them as Millennials. More than 100 ECRs from seven countries were questioned annually, and questions about Sc‐Hub were raised as part of discussions about discovery and access. Interview data were supplemented by desk research and Google Trends statistics. It was found that Sci‐Hub use was increasing and that a quarter of the ECRs now use it, with French ECRs being the biggest users. However, Sci‐Hub is making little headway with ECRs from the UK, USA, Malaysia, and China, although in China's case, this can be explained by it being banned and the country having its own equivalent, www.91lib.com . Sci‐Hub is used as much for convenience as necessity; use is not connected to the strength of library provision and and it has been suggested that it represents a bigger threat to publishers than ResearchGate, whose star might be waning.  相似文献
