Item SOUTH KOREAN FAMILIES’ CONCEPTUALIZATIONS OF MUSEUM-BASED SCIENCE LEARNING(2020) Jeong, Hannoori; Elby, Andrew; Education Policy, and Leadership; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)This exploratory research study examined how three South Korean families in theU.S. conceptualize museum-based science learning by exploring varied contexts in which they are embedded. In applying a sociocultural perspective, I investigated the families’ backgrounds, views of school and museum learning, in conjunction with their virtual museum tours to address my overarching research question: How do South Korean families in the U.S. conceptualize museum-based science learning? The purpose of this study is to understand how, or by what means, South Korean families’ conceptualizations about museum-based science learning are socially and culturally situated. In adhering to the guidelines of Yin’s (2018) suggestions to conduct multiple case research, I collected individual interviews prior to and following the families’ self-guided virtual museum tours, observations, self-reflections, and self-generated photographic images that captured their views of museum learning. Guided by the Contextual Model of Learning framework (Falk & Dierking, 2000), I used three analytic lenses to explore and analyze the data: personal context, sociocultural context, and physical context of learning. Through the use of narrative analysis, I reported within-case and cross-case findings across the three cases of families. In doing so, I first synthesized each family’s background setting, views of school and museum learning, and museum-based learning interactions to seek insights into how they shaped the family’s conceptualizations about museum-based science learning. Findings showed that the interweaving of each family’s varied contexts, namely personal, sociocultural, and physical, appeared to shape how they conceptualized museum-based science learning. Aspects of the families’ personal context—such as individual goals and beliefs—appeared to motivate their learning experience during the virtual museum tours mediated by sociocultural and physical contexts—such as within- group interactions and orientations to the physical space, respectively—that reinforced or shaped their conceptualizations of museum learning. Thus, in connection with prior literature, the families’ views of learning and authoring their sense of self that manifest their unique contexts may have spurred their conceptualizations of museum-based science learning. Broad implications of the study for museum education research, virtual museum learning, and future research related to informal science education are also discussed.Item Revisiting the silence of Asian immigrant students: The negotiation of Korean immigrant students' identities in science classrooms(2012) Ryu, Minjung; Edwards, Ann Ryu; Curriculum and Instruction; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)This dissertation is a study about Korean immigrant students' identities, including academic identities related to science learning and identities along various social dimensions. I explore how Korean immigrant students participate in science classrooms and how they enact and negotiate their identities in their classroom discursive participation. My dissertation is motivated by the increasing attention in educational research to the intersectionality between science learning and various dimensions of identities (e.g., gender, race, ethnicity, social networks) and a dearth of such research addressing Asian immigrant students. Asian immigrant students are stereotyped as quiet and successful learners, particularly in science and mathematics classes, and their success is often explained by cultural differences. I confront this static and oversimplified notion of cultural differences and Asians' academic success and examine the intersectionality between science learning and identities of Asian immigrant students, with the specific case of Korean immigrants. Drawing upon cultural historical and sociolinguistic perspectives of identity, I propose a theoretical framework that underscores multiple levels of contexts (macro level, meso level, personal, and micro level contexts) in understanding and analyzing students' identities. Based on a year-long ethnographic study in two high school Advanced Placement Biology classes in a public high school, I present the meso level contexts of the focal school and biology classes, and in-depth analyses of three focal students. The findings illustrate: (1) how meso level contexts play a critical role in these students' identities and science classroom participation, (2) how the meso level contexts are reinterpreted and have different meanings to different students depending on their personal contexts, and (3) how students negotiated their positions to achieve certain identity goals. I discuss the implications of the findings for the science education of racially, ethnically, and linguistically diverse students, particularly given the increasing number of immigrant students in U.S. classrooms, and for the education of Asian immigrant students.Item AN INVESTIGATION OF STUDENTS' EXPERIENCES WITH A WEB-BASED, DATA-DRIVEN WRITING ASSISTANCE ENVIRONMENT FOR IMPROVING KOREAN EFL WRITERS' ACCURACY WITH ENGLISH GRAMMAR AND VOCABULARY(2010) Lim, Mi-Sun; Oxford, Rebecca L.; Curriculum and Instruction; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Computer-assisted language learning (CALL) has played an increasingly important role in writing instruction and research. While research has been conducted on English as a second language (ESL) learners and the benefits of using web-based writing assistance programs in writing instruction, insufficient research has been done on English as a foreign language (EFL) students. This study is an empirical investigation of students' experiences with a web-based, data-driven writing assistance environment (e4writing) designed by the researcher to help Korean EFL writers with their grammar and vocabulary. This study investigated Korean university students' perceived difficulties with English grammar and vocabulary as they wrote in English. It also explored their perceptions of e4writing as used in a writing course to enhance English grammar and vocabulary. This study investigated 12 participants' perceptions and "academic profiles" (learning styles, confidence, motivation, and other factors) when they were enrolled in a 16-week course called Teaching Methods for English Composition. To gain a more specific and personal view, the study also included detailed case studies of four of the study participants. The major sources of data for the analyses include interviews, reflective journals, questionnaires, samples of the students' writing before and after their use of e4writing and the researcher's reflective notes. The study revealed that most of the students had difficulty with grammar and vocabulary in English writing. They positively perceived e4writing, as it provided individualized help on their problems with grammar and lexis. Overall, the students showed improvement in accuracy from the pretest to the posttest, and observations suggested that e4writing was probably related to this improvement; however, strong claims about e4writing as a cause of improvement cannot be made without a control group. The students felt e4writing was more beneficial for improving grammatical accuracy than for vocabulary accuracy. The students recommended that some features of e4writing be written in Korean to help students understand grammar and vocabulary explanations.
