This study is to examine brain regions that are involved in picture encoding in normal adults using fMRI methods. In Scan 1, the picture encoding was studied during a semantic categorization task in comparison with word. In Scan 2 task type effects were studied both during a picture naming task and during a semantic categorization task with pictures. Subjects were asked to make decision either by pressing a mouse button (Scan 1) or by responding subvocally (naming or saying yes/no) (Scan 2). Regardless of stimulus type, left prefrontal, bilateral occipital, and parietal activations were observed during semantic processing in comparison with fixation baseline. Processing of word stimulus relative to picture resulted in activations in prefrontal and parieto-temporal regions in the left side while that of picture stimulus relative to word resultd in activations in bilateral extrastriatal visual cortices and parahippocampal regions. In spite of the same task demands, stimulus-specific information processings were involved and mediated by different neural substrates; the word encoding was associated with more semantic/lexical processings than pictures and the picture processing associated with more perceptual and novelty related information processings than word. Activations of dorsal part of inferior prefrontal region, i.e., Broca's areas were found both during the picture naming and during the semantic tasks subvocally performed Especially, during the picture naming task, greater occipital activations were found bilaterally relative to the semantic categorization task. indicating a possibility that greater and higher visual processing was involved in retrieving the name referred by picture stimuli.

This study measured various types of joint book reading behaviors of parents of preschool children using two different text genres. Participants were the parents of 35 preschool children 4 years of age. Parent-child dyads were videotaped during periods of joint book reading using two different types of text(informational and narrative). Results indicated differences in maternal behavior between the two types of texts. The informational book elicited a higher amount of print concept behaviors and more content behavior while reading the narrative book. Among content-related behaviors parents used more labeling during the informational genre. On the other hand, parents' use of description and judgment were significantly higher in the narrative genre compared with the informational genre.

The purpose of this study was to analyze children's perspectives on the role of male childcare teachers and children' s gender role concepts. According to the results, when it comes to how the children perceive the roles of the male childcare teacher, the children mostly saw the male childcare teacher as a person who teaches and in another case, they regarded him as someone who takes care of their daily life and who is willing to play games with them. On the other hand, the male childcare teacher's organizing of an environment, supporting tasks and working on a computer were perceived less by the children. In terms of the gender role concepts, the study confirmed that depending on the role performance of the male childcare teacher, the children in the male childcare teacher's class had better understanding than those children in the female childcare teacher's class. In order to secure the children's right to participate specified in the convention of the rights of the child, the study applied not only the interviews with the children but also their drawings to the analysis, and that was what led the study to an in-depth discussion on the perception of the children.

This study investigated the effect of systematicity and presentation type of an analog upon students' concept recall and application regarding stoichiometry that included limiting reagent. Systematicity was manipulated by varing the degree of explicit causal structure, and presentation type was in either verbal format or verbal/figurative format. The four types of the analog developed were studied by randomly assigned junior high school students (N=137). Prior to the treatment, the Group Assessment of Logical Thinking was administered and its score was used as a covariate. After the treatment, a research-made conception test was administered immediately and four weeks later. The ANCOVA results indicated that systematicity had a positive effect on immediate application regardless of presentation type. In the application problem of retention test, however, systematicity had no main effect but interaction with presentation type. These suggested that the systematic analog in verbal/figurative format most positively influence concept application. Educational implications are discussed.

The purpose of this study is to investigate how elementary school students understand and use the number line relating number concept and what is the main problem in the learning process. For the efficient achievement of this purpose, we investigated how the number line metaphor is related to the number concept and considered the role of the number line on Freudenthal's number concept teaching theory. The test conducted to find the degree of understanding and difficulty on using the number line by actual elementary school students consisted of two questions ; to find appropriate number corresponding to the given number on the number line and to identify contents of chapters about the use of number line on each grade. It was found that many students couldn't solve the problem represented by the number line though they could solve the problem represented by other ways such as number track and pictures. The only difference between the two problems was the way of representation, and they had same contents and structure. This study tried to figure out the meaning of this phenomenon. Also, by using various teaching-learning method (number track, pictures, empty number line, and double number line etc.), this study was aimed to provide the way to help learning 'related number concept' and to solve the difficulty on understanding the number line.

The purpose of this study was to qualitatively examine the meaning of students' drawings in outdoor classes and modeling-based learning cycles. Ten students were observed in a gifted education center in Seoul. Under the theme of the Hantan River, three outdoor classes and three modeling activities were conducted. Data were collected to document all student activities during field trips and classroom modeling activities using simultaneous video and audio recording and observation notes made by the researcher and students. Please note it is unclear what this citation refers to. If it is the previous sentence it should be placed within that sentence's punctuation. Hatisaru (2020) Ddrawing typess were classified by modifying the representations in a learning context in geological field trips. We used deductive content analysis to describe the drawing characteristics, including students writing. The results suggest that students have symbolic images that consist of geologic concepts, visual images that describe topographical features, and affective images that express students' emotion domains. The characteristics were classified into explanation, generality, elaboration, evidence, coherence, and state-of-mind. The characteristics and drawing types are consecutive in the modeling-based learning cycle and reflect the students' positive attitude and cognitive scientific domain. Drawing is a useful tool for reflecting students' thoughts and opinions in both outdoor class and classroom modeling activities. This study provides implications for emphasizing the importance of drawing activities.

The purposes of this study were to identify the misconceptions that students have on the magma and plate tectonics and to present the implications in developing textbooks as well as related curriculum of high school textbooks. Data were collected through questionnaire, consisting of some questions, short essays, and descriptive drawings, developed by the research team. A total of 140 high school students(9th graders) responded to those questionnaires and were interviewed for further information. It was reported that participants displayed various misconceptions related to magma and plate tectonics. The identified misconceptions are as follows: For the definition of magma, the 31% of participants misunderstood magma as lava. In respect to the generative mechanism of magma at subduction zone, over 90% of students responded that it is generated by frictional heat. The source of misconceptions were identified as a result from textbooks and related reference-books. For the concept of plates, 87% of students conceived 'crust or a lower part of the plates' as 'plates'. Most participants hold the right concept of oceanic ridge, whereas, 66% of them considered 'rift valley' as either 'divergence of continental plates' or 'converging boundary'. 63% of them defined 'collision boundary of continental plate' as either 'subduction zone' or 'diverging boundary'. For the definitions of the trench and Benioff zone, 86% of students responded them as the place of subduction or differing density between two converging plates. The students' misconceptions were resulted from the errors and insufficient explanation, inappropriate figures, and data presented in textbooks, reference-books, lecture, and web sites. The results of this study are implied to contribute the improvement of students' misconceptions.

Ninety-eight bestselling children's picture books from 2008 to 2014 were analyzed for multicultural education. The criteria used for the analysis included Culture, Diversity, Identity, Equity, Anti-bias, and Cooperation that were drawn from Kim & Park (2011). An examination of the books revealed that they contained concepts of Cooperation, Identity, Culture, and Diversity in their orders of frequency while ideas of Equity and Anti-bias were barely depicted. Differences between domestic and translated books were found. Translated picture books reflected Diversity more frequently than domestic ones. Under a criterion of Culture, Recognizing Differences and Similarities was more frequently portrayed in translated books while Respecting for Cultures was more frequently found in domestic ones. Findings were discussed in terms of bestselling picture books' limitations of dealing with critical multicultural issues, domestic picture books' lack of reflection of changing multicultural realities, fantasy picture books'dealing with critical multicultural issues through metaphors, and possible problems of the books conveying biased or confusing messages. It was suggested that an adult's role is essential when the bestselling literature is used for the purpose of multicultural education. Their deliberate guidance can help young children engaged in critical issues of race, gender, and ability and develop their multicultural sensitivities through literature.
