This study aimed to discern the educational meaning of nature experience activity in a nonformal educational program in Korea, focusing on the interaction between a teacher and learners. To achieve this objective, an ethnographic research method was employed using an environmental educational program for children in a nonformal setting. The results of study are as followings. Firstly, the teacher's belief-"young ecologist" shaped its own characteristics of the program. Secondly, the children had a understanding that they learn something about nature(e.g. learning by seeing, dlscovering, recollecting, and awakening). The analysis of teachers' ideas and learners' attitude toward nature experience shows that there exists a gap between the teachers' expectations and the actual ecological changes in the learners' ideas. However, the educational meaning of nature experience can be understood by the unique type of interaction between a teacher and learners. In conclusion, on the basis of this study, it is suggested that educators should be aware of the fact that nature experience can conttribute significantly to the education of children not just from the encounter with nature but also philosophically with regard to our connectedness with nature. Bringing nature into educational contexts can help children to take part in thoughtful perspectives of learning and to devise their own appropriate nature experience.

This paper investigates how adult Mandarin- and English- speaking learners of Korean perceive Korean vowels, with focus on the effect of the first language (L1) and the second language (L2) acoustic relationship, as well as the influence of Korean language experience. For this study, native Mandarin and Canadian English speakers who have learned Korean as a foreign language, as well as a control group of native Korean speakers, participated in two experiments. Experiment 1 was designed to examine acoustic similarities between Korean and English vowels, as well as Korean and Mandarin vowels to predict which Korean vowels are relatively easy, or difficult for L2 learners to perceive. The linear discriminant analysis (Klecka, 1980) based on their L1-L2 acoustic similarity predicted that L2 Mandarin learners would have perceptual difficulty rankings for Korean vowels as follows: (the easiest) /i, a, e/ >> /ɨ, ʌ, o, u/ (most difficult), whereas L2 English learners would have perceptual difficulty rankings for Korean vowels as follows: (the easiest) /i, a, e, ɨ, ʌ/ >> /o, u/ (most difficult). The goal of Experiment 2 was to test how accurately L2 Mandarin and English learners perceive Korean vowels /ɨ, ʌ, o, u/ which are considered to be difficult for L2 learners. The results of a mixed-effects logistic model revealed that English listeners showed higher identification accuracy for Korean vowels than Mandarin listeners, indicating that having a larger L1 vowel inventory than the L2 facilitates L2 vowel perception. However, both groups have the same ranking of Korean vowel perceptual difficulty: ɨ > ʌ > u > o. This finding indicates that adult learners of Korean can perceive the new vowel /ɨ/, which does not exist in their L1, more accurately than the vowel /o/, which is acoustically similar to vowels in their L1, suggesting that L2 learners are more likely to establish additional phonetic categories for new vowels. In terms of the influence of experience with L2, it was found that identification accuracy increases as Korean language experience rises. In other words, the more experienced English and Mandarin learners of Korean are, the more likely they are to have better identification accuracy in Korean vowels than less experienced learners of Korean. Moreover, there is no interaction between L1 background and L2 experience, showing that identification accuracy of Korean vowels is higher as Korean language experience increases regardless of their L1 background. Overall, these findings of the two experiments demonstrated that acoustic similarity between L1 and L2 sounds using the LDA model can partially predict perceptual difficulty in L2 acquisition, indicating that other factors such as perceptual similarity between L1 and L2, the merge of Korean /o/ and /u/ may also influence their Korean vowel perception.

The current study investigated whether Korean learners' English-learning environments, especially target English accent (General American English (GAE) vs. Southern British English (SBE)) and English-language experience affected their production of English vowels. Thirty six EFL learners, 27 ESL-US learners, and 33 ESL-UK learners produced 8 English vowels with a bVt frame (beat, bit, bet, bat, bought, bot, boat, boot). The learners' productions were acoustically analyzed in terms of F1 and F2 frequencies. The overall results revealed that the learners' target accent had an effect on their production of some English vowels. The EFL and ESL-US learners' (especially, female learners') production of bought, bot, boat, and boot, which show characteristic differences between the GAE and SBE accents, was closer to that of the native American English (AE) speakers than the native British English (BE) speakers. In contrast, the ESL-UK learners' production of bought and bot demonstrated the opposite pattern. Thus, the impact of target accent was not demonstrated across the board. The effect of the learners' different English-language experience was also rather limited. This was because the EFL learners' production was not much different from the ESL-US learners' production, in spite of the ESL-US learners' residence in the US for more than 9 years. Furthermore, the Korean learners, irrespective of their different English-language experience, tended to produce bit and bat with lower F1 than the native AE and BE speakers, thus resulting in bit and bat to be produced similarly to beat and bet, respectively. This demonstrates the learners' persistent L1 effects on their English vowel production despite the learners' residence in the English speaking countries or their high English proficiency.

This study examined which acoustic cue(s) that Korean learners of English give weight to in perceiving English lexical stress. We manipulated segmental and suprasegmental cues in 5 steps in the first and second syllables of an English stress minimal pair "object". A total of 27 subjects (14 native speakers of English and 13 Korean L2 learners) participated in the English stress judgment task. The results revealed that native Korean listeners used the F0 and intensity cues in identifying English stress and weighted vowel quality most strongly, as native English listeners did. These results indicate that Korean learners' experience with these cues in L1 prosody can help them attend to these cues in their L2 perception. However, L2 learners' perceptual attention is not entirely predicted by their linguistic experience with specific acoustic cues in their native language.

In knowledge based society, lifelong learning is increasing in order to meet educational needs of adult learners. Credit Bank system which is credited by individual experience, learning and qualifications are also emphasized for continuing learning participation. However, in spite of the importance of concern in the Credit Bank System, adult learners expectation and value are not high. The purpose of this study is to analyze participation valence and learning flow of adult learner in the Credit Bank System. The result of this study is summarized as follows: first, adult learners participated in the Credit Bank System to get new knowledge and skill based on internal and external motivation and requirement not involved with individual degree. Second, adult learners participating in the Credit Bank System are experiencing learning flow realizing that behavior of participation is compensated, adult learners are concentrating and feeling with satisfaction and pleasure to study. Third, participation in the Credit Bank System based on adult learner's own right learning requirement have been analyzed as it has a positive effect to the learning flow and have indicated that adult learners having high level of valence experience, recognition immersion, behavioral devotion, and egoistic immersion. Based on the conclusion, further studies are suggested.

This study analyzed the learning effect, through a satisfaction survey and NVivo qualitative analysis, of fashion design classes using humanities self-reflection writing. The results are as follows. First, with regard to learning satisfaction, learners perceived the class as efficient and showed overall satisfaction. Second, learners' opinions were classified into self-reflection writing, design process, new experience of expression, and the understanding of class activities. Third, in self-reflection writing, learners discovered their tendencies and values while exploring their identity through deep thinking. Fourth, in the design process, learners set the design concept consistently through writing. Fifth, in the new experience of expression, learners recognized the idea produced through writing as the result of thought and considered it a new expression method for design. Sixth, in the understanding of class activities, learners were interested in the process and considered it an activity through which to build their own style in design expression. Design class activities using self-reflection writing drew a positive response and presented the possibility of educational use. The teaching method of this study is expected to be used as a humanistic method for expressions in various design fields.
