The effects of worked examples in computer-based instruction: focus on the presentation format of worked examples and prior knowledge of learners

권선아,Hyunjeong Lee 서울대학교 교육연구소 2009 Asia Pacific Education Review Vol.10 No.4

The aim of this study is to investigate the effects of presentation formats of worked examples and the interaction effects between the presentation formats of worked examples and the prior knowledge of learners. An investigation with 97 middle school students working in four conditions (CPWE, CWE, PWE, and the control group) was conducted. The results indicate that CPWE was the most effective condition in retention and transfer. In addition, a partial expertise reversal effect was revealed in the element transfer test. High prior knowledge learners in both CPWE and PWE were superior to those who were in CWE and the control group, while low prior knowledge learners in CPWE were superior to those who were in other conditions.

권선아,양유정 한국방송통신대학교 미래원격교육연구원 2023 평생학습사회 Vol.19 No.3

This study aimed to confirm the effect of undergraduate students’ digital learning self-efficacy on learning engagements in real-time online classes and to verify the mediating effect of positive and negative academic emotions in the relationship between digital learning self-efficacy and learning engagement. To achieve this, a research model was created based on previous studies, which was then verified based on 237 undergraduate students, confirming the mediating effect. The findings established that digital learning self-efficacy had a positive effect on engagement in real-time online learning; however, learning engagement was found to be affected in different ways when academic emotions were mediated. In other words, when positive academic emotion was mediated, digital learning self-efficacy directly and indirectly had a significant positive effect on learning engagement; however, when mediated, negative academic emotion was found to have an indirect negative effect on learning engagement. The significance of positive and negative academic emotions in real-time online classes was examined based on these results, and implications for increasing engagement in learning were proposed.

The aim of this study is to analyze the level of pre-service secondary teachers' recognition of metaverse and metaverse applied education to explore research and practice directions that can be used as evidence by education researchers and school education stakeholders. In order to achieve the purpose of this study, a survey was conducted on 66 pre-service secondary teachers, and the results of the survey were analyzed using a chi-square (χ2) test according to the background variables (major, year of birth) of the learners. As results, all of the pre-service secondary teachers who participated in the survey were born after 1980 and were all classified as the MZ generation, and there was no difference in recognition level according to their background variables. Regardless of major and year of birth, the results of analysis are as follows. First, there were no respondents who answered that they did not know anything about the metaverse (0%), and most of the respondents answered that they knew to some extent (77.3%) or knew very well (7.6%). Second, regarding the utilization of the metaverse, most respondents answered that it is a space where work and study can be carried out effectively (34.8%) and an expansion space in the real world where production and consumption activities are possible (27.3%). Third, as for the opinions on metaverse application education in secondary education, most responded positively (69.7%). Fourth, 47% of the respondents answered that it could be used as a supplementary space for school education, and 37.9% of the respondents said that it could be used as an independent space rather than a supplementary space. In the conclusion, the implications of these research results and suggestions for follow-up studies were discussed.

권선아,이재경,장지영 사단법인 미래융합기술연구학회 2021 아시아태평양융합연구교류논문지 Vol.7 No.7

Recently, some researchers in the field of education have been interested in the applications of Blockchain technology. While some researchers have conducted on the ‘academic certificate handling’ or ‘managing record-keeping’ in which are detailed educational administrative sector, others are more interested in reshaping educational landscape based on the key concept of ‘decentralization’ of Blockchain technology in a larger educational context. Researchers believe that the current centralized learning system or educational model is no longer sustainable, and that the Blockchain technology allows for a total disintermediation and disaggregation of education, specifically in higher education including lifelong learning. In a similar context, this paper will explore how the concept of ‘decentralization’, which is core concept of Blockchain technology, can transform the landscape of education, specifically focusing on the suggestions of researchers at Knowledge Media Institute at the open university in the UK. In other words, it will investigate how this new paradigm of Blockchain technology can affect on educational domain. To achieve this purpose, firstly, the basic Blockchain technology will be scrutinized, followed by the current major research outcome of educational applications of Blockchain technology will be reviewed. Finally, the implications and future prospects of educational applications of the Blockchain technology will be discussed.

권선아,양명희 교육종합연구원 2017 교육종합연구 Vol.15 No.4

The purpose of this study is to analyse the longitudinal relations between self-regulated learning, social relationship and computer use of adolescent. For this purpose, multivariate latent growth model was verified, using three year longitudinal panel data of Korean Children and Youth Panel Survey (2012, 2014, & 2015). In analysis of the effects of computer use, the use of computer was divided into ‘for learning’ and ‘for non-learning’. Results indicated that ‘computer use for learning’ was positively related with self-regulated learning in the period of K9, and this relation was still valid as their grade goes up. However, the ‘use of computer for non-learning’ was negatively related with self-regulated learning and there was no valid relationship as their grade goes up. Lastly, there was no direct influence of computer use on the social relationship of adolescent, regardless of the computer use for ‘learning’ or ‘non-learning’. Based on these results, the implications were discussed.

권선아,정연아 교육종합연구원 2024 교육종합연구 Vol.22 No.1

The purpose of this study was to explore the possibility of applying the metaverse in early childhood education and care, based on the results of the analysis of early childhood education and care teachers' perceptions and opinions about 'metaverse' and 'metaverse applied education.' To achieve this goal, a survey was conducted with 112 teachers working at kindergartens and childcare centers in Seoul and the Gyeonggi province. Among them, 8 were selected for interviews, and the results were analyzed. The analysis revealed the following: First, the level of awareness of the metaverse and metaverse application education among early childhood education and care teachers was generally low. However, for teachers in their 30s with 5-15 years of experience, it was relatively high compared to other groups. Second, the metaverse application education proposed by teachers was found to be related to the curriculum areas of 'Physical Exercise and Health,' 'Communication,' and 'Social Relations' in the 2019 revised Nuri Curriculum. Based on these results, discussions and implications were presented regarding the application of the metaverse in early childhood education and care.
