The specific objectives of the study were (1) to determine the preferences for three home economics curriculum designs(HECD) categorized by Majorie Brown(Technical HECD, Self Actualization HECD, and Practical Reasoning HECD), (2) to determine the differences between middle school HE teachers and high school HE teachers on each curriculum element, and (3) to determine the relationships between preferences for three HECD by curriculum elements and personal and professional characteristics of HE teachers. For these objectives, the subjects were randomly selected from HE teachers of secondary schools in the areas of Seoul, In-Cho, and Keungi. The 300 data collected by mailed survey were analyzed into frequency, percentage, Chi-square, and contingency coefficient using SAS program. The major findings were as follows: 1) the majority of HE teacher respeondents preferred the Practical Reasoning HECD about the following curriculum elements: Purpose of HE education, knowledge, subject matter, teaching method, society and culture, learner, learning atmosphere, and HE teacher's role. 2) No significant difference emerged when Chi-square was applied to determine difference between the two groups(middle and high school HE teachers) on three HECD according to each curriculum element. 3) The contingency coefficient between preferences of HE education purpose for three curriculum designs and age was 21, years of teaching was 23, between preferences of learning atmosphere of three curriculum designs and location of school was. 17. These mean that the younger and more beginning teachers perferred HE purpose of the Practical Reasoning HECD, and HE teachers working in urban area more preferred learning atmosphere of Practical Reasoning HECD.

The goal of this study was to understand the reasons for learning about Korean herbal food by examining the actual conditions in a Korean herbal food course during lifestyle education. The general characteristics of the people learning about or working with the food as well as the correlations between the examined factors were analyzed, focusing on each person's dietary lifestyle. We divided the class participants into five dietary lifestyle groups by analyzing their scores. Group 1 was the"taste-seeking type", group 2 was the "quality-seeking type", group 3 was the"economy-seeking type", group 4 was the"convenience and economy-seeking type", and group 5 was the"convenience and health-seeking type". A person with a cooking career was considered to have more experience with Korean herbal food. The highest motivation for Korean herbal food education was for professional reasons, and the class that was most appreciated was learning about Korean traditional herbal foods. The highest satisfaction for the class was based on the instructor's knowledge, followed by food tastes, foodstuffs, educational materials, and the facilities superintendent. Satisfaction with the class tuition and practical utilization was relatively low.

Research shows that formative assessment has a more powerful effect on student learning than summative assessment. This case study of an 8th grade algebra classroom focuses on how the implementation of Formative Assessment Lessons (FALs) and the participation in teacher learning communities related to FALs changed in the teacher's instructional practices, over the course of a year, to promote students' mathematical reasoning and justification. Two classroom observations are analyzed to identify how the teacher elicited and built on students' mathematical reasoning, and how the teacher prompted students to respond to and develop one another's mathematical ideas. Findings show that the teacher solicited students' reasoning more often as the academic year progressed, and students also began developing mathematical reasoning in meaningful ways, such as articulating their mathematical thinking, responding to other students' reasoning, and building on those ideas leading by the teacher. However, findings also show that teacher change in teaching practices is complicated and intertwined with various dimensions of teacher development. This study contributes to the understanding of changes in teaching practices, which has significant implications for teacher professional development and frameworks for investigating teacher learning.

In recent research, deep learning-based methods have achieved state-of-the-art performance in various computer vision tasks. However, these methods are commonly supervised, and require huge amounts of annotated data to train. Acquisition of data demands an additional costly effort, particularly for the tasks where it becomes challenging to obtain large amounts of data considering the time constraints and the requirement of professional human diligence. In this paper, we present a data level synthetic sampling solution to learn from small and imbalanced data sets using Generative Adversarial Networks (GANs). The reason for using GANs are the challenges posed in various fields to manage with the small datasets and fluctuating amounts of samples per class. As a result, we present an approach that can improve learning with respect to data distributions, reducing the partiality introduced by class imbalance and hence shifting the classification decision boundary towards more accurate results. Our novel method is demonstrated on a small dataset of 2789 tomato plant disease images, highly corrupted with class imbalance in 9 disease categories. Moreover, we evaluate our results in terms of different metrics and compare the quality of these results for distinct classes.

Purpose: While clinical practice is crucial for nursing students to acquire the skills needed to provide professional, high-quality nursing care, further studies on improving undergraduate nursing programs are needed to provide a supportive clinical learning environment for student nurses. This study aimed to understand nursing students' clinical experiences in newborn nurseries and neonatal intensive care units and to provide basic data for the establishment of strategies to promote effective clinical education. Methods: Interviews were held with 15 nursing students at J University who had clinical practice experience in the newborn nursery and neonatal intensive care unit. The collected data were analyzed using the phenomenological analysis method developed by Colaizzi (1978). Results: The nursing students' experiences were grouped into four categories: "expectations for and anxiety about clinical practice", "acquisition of a wide range of knowledge regarding neonatal nursing", "challenges faced in clinical practice", and "experiencing interpersonal changes". Conclusion: The current neonatal practice nursing education system provides students with positive learning experiences. However, the lack of practice opportunities, insufficient instruction, and the theory-practice gap were identified as major issues hindering students' learning needs. These study results are expected to provide basic data for curriculum development to improve undergraduate nursing education.

This study investigated how learning motivation affects satisfaction with training and employment services and its performance for participants in government-supported job skill development program of the clothing industry so as to provide fundamental data for developing a training program that fosters professionals and relieves the labor shortage in the clothing industry. 180 copies of questionnaires were statistically analyzed by SPSSWIN 21.0. Most trainees were low-income citizens in their 40s and 50s. They were divided into highly educated or low-educated. The results of the research are as follows: when the trainees were motivated by the goals of getting a certificate or a job, employment service satisfaction levels were influenced meaningfully. Secondly, educational satisfaction levels and occupational ability development also scored highly. Therefore, it is important to strengthen instructors' competency. Instructors must be required to have onsite experience so that they can provide authentic education that can be applied to the work field. The government should establish a compulsory training session for the trainers along with an incentive program so that they can catch up with up-to-date technology and trend. Third, the research shows that supporting business startup and job placement is important. Follow-up management systems should be provided in cooperation with relevant institutions of employment and business startups. Either outsourcing or placement of professional advisors is also needed.
