차현정,윤혜경,박정우 한국초등과학교육학회 2022 초등과학교육 Vol.41 No.3

In this study, the perception and demands on the use of realistic content were analyzed through in-depth interviews with elementary school teachers experienced in using realistic content in science classes. Specifically, the following questions were investigated: (1) What kind of realistic content and how do elementary school teachers use it in science classes? (2) What are the perceptions and difficulties of elementary school teachers regarding the use of realistic content in science classes? (3) What are the needs of elementary school teachers related to the professional development program for the use of realistic content in science classes? The study revealed the following results. First, elementary school teachers mainly used digital textbooks and realistic content provided by the “Science Level Up” site, and the content types could be classified into “exploration type,” “visit type,” and “production type,” according to the purpose of use. Second, elementary school teachers mentioned the educational advantages of using realistic content to help students understand scientific content, induce interest and curiosity, and become immersed in a sense of reality. Several difficulties related to the use of realistic content were mentioned. Among them, the lack of high-quality educational content suitable for science classes and a lack of examples of specific class cases that use realistic content stood out. Thirdly, regarding the development of teacher expertise to use realistic content, elementary school teachers emphasized the need for information on quality realistic content; teacher training centered on specific class cases; instructional models that can be applied by realistic content type; and information on the purchase, use, management, and operation of necessary devices. Reflecting on these research results, implications for more effective use of realistic content in elementary science classes were discussed. 이 연구에서는 과학 수업에서 실감형 콘텐츠를 활용한 경험이 많은 초등 교사를 대상으로 심층 면담을 통해 실감형 콘텐츠의 활용에 대한 인식과 요구 사항을 분석하였다. 구체적으로 (1) 과학 수업에서 초등 교사는 주로 어떠한 실감형 콘텐츠를, 어떠한 방식으로 활용하고 있는지, (2) 과학 수업에서 실감형 콘텐츠 활용에 대한 초등 교사의 인식과 어려움은 무엇인지, (3) 과학 수업에서 실감형 콘텐츠 활용을 위한 연수에서의 초등 교사의 요구 사항은 무엇인지에 관해 알아보았다. 연구 결과 첫째, 초등 교사는 주로 디지털교과서와 ‘사이언스레벨업’ 사이트에서 제공하는 실감형 콘텐츠를 사용하였고 콘텐츠 유형은 활용 목적에 따라 ‘탐구형’, ‘방문형’, ‘제작형’으로 분류할 수 있었다. 둘째, 초등 교사들은 실감형 콘텐츠 활용의 교육적 장점으로 과학 내용 이해에 도움, 흥미와 호기심 유발, 실재감을 통한 몰입을 언급하였다. 실감형 콘텐츠 사용과 관련된 어려움은 여러 가지가 언급되었으나 과학 수업 내용에 적합한 양질의 교육용 콘텐츠가 매우 부족하다는 점, 실감형 콘텐츠를 활용할 수 있는 구체적인 수업 사례의 예시가 부족하다는 점 등이 있었다. 셋째 실감형 콘텐츠 활용을 위한 교사 연수와 관련해서 초등 교사들은 질 좋은 실감형 콘텐츠에 대한 정보 제공, 구체적인 수업 사례 중심의 연수, 실감형 콘텐츠 유형별로 적용해 볼 수 있는 수업 모형의 제공, 필요한 기기의 구입, 사용, 관리 및 운영에 관련된 정보 안내가 필요함을 강조하였다. 이러한 연구 결과를 반영하여 초등 과학 수업에서 실감형 콘텐츠를 보다 효과적으로 활용하기 위한 시사점을 논의하였다.

The purpose of this study is to explore whether drawing activities using synectics technique affect young children’s drawing expression. According to the above study purpose, research questions were set up as follows. 1. What effects do drawing activities using synectics technique have on young children’s drawing expression? 1) What effects do drawing activities using synectics technique have on young children’s representation level? 2) What effects do drawing activities using synectics technique have on young children’s exploration level? 3) What effects do drawing activities using synectics technique have on young children’s artistry level? The objects of this study were 32 young children aged 5 years attending 2 classes of B and S kindergarten in Cheongjoo-Si, Chungcheongbuk-Do, Korea. The experiment group were 16 young children(male: 10, female: 6) aged 5 years of B kindergarten; the control group were 16 young children(male: 6, female: 10) aged 5 years of S kindergarten. The research tool of this study was based on Evaluation Scales(Chen & Feinburg, 1990) in the visual arts domain of Project Spectrum(Krechevsky, 1998). And, this study employed the tool of Choi Hyeon-Yi(2010) which was developed from that of Kang Young-Soo(1999) who had adapted the Evaluation Scales to assess drawing expression. The experimental treatment of drawing activities using synectics technique was done from 18(Mon.) May to 23(Thu.) July, 2015 for 10 weeks each of which was one session. For the data processing in investigating the effects of drawing activities using synectics technique on 3 categories of drawing expression which include representation, exploration and artistry level, the means and standard deviations of pre- and post-test scores were calculated for both the experiment and control group. And, T-test was done for the increment which was post-score subtracted of pre-test score. The results of this study are as follows. First, the score of drawing expression in the experiment group who participated in drawing activities using synectics was more than that in the control group and there was statistically significant difference(p<.001) which means drawing activities using synectics had a positive effect on young children’s drawing expression. Second, the scores of 3 sub factors(representation, exploration and artistry level) of drawing expression in the experiment group who participated in creative drawing activities using synectics were more than those in the control group and there were statistically significant differences(p<.01, p<.001). In detail, statistically significant differences at the representation level and the exploration/artistry level were p<.01 and p<.001 respectively. The above results means drawing activities using synectics had a positive effect on young children’s drawing expression. The conclusions based on the above results of this study are as follows. First, drawing activities using synectics had a positive effect on young children’s drawing expression. Second, drawing activities using synectics had a positive effect on the representation level of young children’s drawing expression. Third, drawing activities using synectics had a positive effect on the exploration level of young children’s drawing expression. Fourth, creative drawing activities using synectics had a positive effect on the artistry level of young children’s drawing expression. The results of this study showed drawing activities using synectics improved the drawing expression of your children in the experiment group. In conclusion, drawing activities using synectics is an effective teaching-learning method for the enhanced drawing expression of young children aged 5 years.

차현정,김대재 충북대학교 과학교육연구소 2010 과학교육연구논총 Vol.25 No.2

This study presents that six of cucumber senescence-associated genes(SAGs) functional identification in silico, time of gene expression and possible biological roles in cucumber senescence. They are sen 4-1, sen 8-6, sen 11-8, sen 15-8, sen 053, and sen 218. The most probable biological function of the cDNA sequences was identified through NCBI-GenBank database investigation using tblastx and blastx searching module. According to the cDNA sequence information, we have designed PCR primers to the six genes for following molecular genetic study. The primers were made by 20 nucleotide length with similar GT contents for appropriate annealing temperature adjustment in PCR study. To investigate the above cucumber genes expression pattern in the cotyledon development, cucumber seeds (Baek Da Da Gi) were sown in wet vermiculite after l2hr imbibition in sterile water. Then growing green cotyledons were collected one-week interval from two week after seed germination until four weeks of cucumber development as NOT in Senescence stage (negative control). After that the following turing point of development from growth to senescence, two pairs of senescing cotyledons were selected with amount of yellow pigment as senescence stage I (50% yellow), II (70% yellow) and stage III (>90% yellow) until 42 days of cucumber development. Subsequently, total RNA purification, cDNA synthesis (reverse transcription), PCR, electrophoresis and UV gel image analysis were carried out by standard molecular biological protocols. Eventually, we have found four noble SAGs (sen 4-1, sen 8-6, sen 15-8 and sen 218) which shows strong developmental coordination in gene expression at the stage of senescence development in cucumber cotyledon. In particular, sen 218 revealed that earlier onset of the gene action in senescence development compare to ICE. The other SAGs start action from stage II to stage III which may be involved in the senescence of cucumber cotyledons. The sen 8-6 and sen 15-8 start action at the stage II of senescence development. So, the sen 8-6 may be involved in the (1-4)-beta-mannan hydrolysis of cucumber cotyledons cell membrane. The sen 15-8 may be involved in the deamination of asparagine to aspartate conversion. Finally, sen 4-1 may be involved in the dephytylation of cucumber cotyledons and leaves. Unfortunately, we did not have acceptable outcomes to the rest of cDNA clones as cucumber SAGs, so further refined study should be done more carefully in the future. In water stress study, cucumber seedlings show morphological change by water stress in this primary study. But, it also need further investigation of the gene expression level to the water-stressed cotyledons in the future study.
