Abstract Backgroundwe combined anatomy with imaging, transformed the 2D information of various imaging techniques into 3D information, and form the assessment system of real medical imaging cases in order to make up for the deficiencies in the current teaching of the medical imaging technology students. MethodsA total of 460 medical imaging students were selected and randomly divided into two groups. The research group received the teaching of the fusion of the original CT and MR data 3D model and the original image combined with 3D anatomical image. Statistical analysis Academic self-efficacy scale and Self-directed learning ability scale was adopted by self-directed learning evaluation scale between two groups.ResultsCompare the theoretical scores and case analysis scores of the two groups. The scores of the study and control groups were significantly higher than those of the control group.Before the experiment, no significant difference was detected in the self-efficacy of learning ability and learning behavior between the two groups , while after the experiment, these differences between the two groups were statistically significan.

Abstract Background We combined anatomy with imaging, transformed the 2D information of various imaging techniques into 3D information, and form the assessment system of real medical imaging cases in order to make up for the deficiencies in the current teaching of the medical imaging technology students. Methods A total of 460 medical imaging students were selected and randomly divided into two groups. The research group received the teaching of the fusion of the original CT and MR data 3D model and the original image combined with 3D anatomical image. CT and MRI data are imported through load DICOM of 3D slicer. Different tissues and organs are segmented by threshold and watershed algorithm of segment editor module. Models are exported through export / import models and label maps in segmentation. Save the NHDR file of the original data and Obj file of the corresponding model through save the NHDR and corresponding Obj files are loaded into probe 1.0 software. The software can give different colors to the three-dimensional models of different organs or tissues to display the stereo models and related data, and display the hook edges of organ models on coronal, sagittal and axial images. At the same time, annotation can be established in the corresponding anatomical position. Finally, it can be saved as a single file of Hwl, and the teaching can be opened at any time through the program of probe 1.0. Statistical analysis Academic self-efficacy scale and Self-directed learning ability scale was adopted by self-directed learning evaluation scale between two groups. Results Compare the theoretical scores and case analysis scores of the two groups. The scores of the study and control groups were significantly higher than those of the control group.

Moreover, the learning ability self-efficacy and learning behavior of the two groups of students after the experiment was significantly higher than that before the experiment. The self-efficacy of the learning behavior of the control group was higher after the experiment than that before the experiment, albeit the difference was not statistically significant.

Purpose: The purpose of this study is to investigate the learning experience, self-directed learning ability and self-efficacy of Japanese nursing students undergoing portfolio-based clinical practicums. Methods: The self-directed learning ability and self-efficacy of nursing students were examined using two scales. And using a text-mining approach, we constructed correspondence analysis followed by cluster analysis of open-ended responses forms. Results: The mean score of the self-directed learning ability was $60.89{pm}5.28$ and the generalized self-efficacy was $68.37{pm}11.56$. Moreover, the scores in the self-directed learning ability were positively correlated with scores in the generalized self-efficacy. In correspondence analysis, the distribution of extracted words showed that record was located on the negative side of the third quadrant, to the first principal component and that patient was located on the positive side of the first quadrant, contributing greatly to the second principal component. Conclusion: The results of this study contribute to approaching to "confidence, pride, stability," "growth and intention to development'' offers a key in developing self-directed learning ability. Students record what they see and learn the importance of visualizing it in learning portfolios. "Expression in detail of the learned contents" and "concerning to which objective evaluation is suggested" are important to the students.

This paper examines what affects adolescents’ English anxiety in the English as Foreign Langauage (EFL) context. A total of 414 adolescents in South Korea participated in the study and the AMOS 20.0 was used in structural equation modeling for statistical analysis. The results are as follows. Girls showed a higher level of English anxiety and self-directed learning ability than boys. Second, adolescents’ English self-efficacy had a partial mediating effect on the relationship between parental pressure expectation and English anxiety. Third, parental pressure expectation had a significant effect on English anxiety through self-directed learning and English self-efficacy. Fourth, a gender difference in the paths of the models was significant. This provides supporting evidence to many educators and parents for the implementation of effective support practices for adolescents who learn English in EFL contexts similar to Korea to reduce thier English anxiety.

The Relationship

The lack of self-directed learning of students shown by students is one problem associated with self-efficacy and the learning environment. The purpose of the research is to reveal the relationship between self-efficacy and the learning environment, and self-directed learning. This study uses the correlational method and data collected from a sample of 198 students, which were found using proportional random sampling techniques. Data were collected using a self efficacy scale (24 valid items = 0.851), a learning environment scale (32 valid items = 0.830), and a self-directed learning scale (64 valid items = 0.936). Data were then analyzed using multiple regression. The results showed the correlation coefficient r = 0.535 and p = 0.00 (p> 0.05), which showed that there was a positive and significant relationship between self-efficacy and the learning environment together with self-directed learning. So it can be explained that the higher the self-efficacy and learning environment, the higher the student's self-directed learning.
