The system to achieve better quality in the educational system is to find the knowledge from educational data and to discover the attributes that manipulate the performance of students. Student performance prediction is a major issue in education and training, specifically in the educational data mining system. This research presents the student performance prediction approach with the MapReduce framework based on the proposed fractional competitive multi-verse optimization-based deep neuro-fuzzy network. The proposed fractional competitive multi-verse optimization-based deep neuro-fuzzy network is derived by integrating fractional calculus with competitive multi-verse optimization. The MapReduce framework is designed with the mapper and the reducer phase to perform the student performance prediction mechanism with the deep learning classifier. The input data is partitioned at the mapper phase to perform the data transformation process, and thereby the features are selected using the distance measure. The selected unique features are employed for the data segmentation process, and thereafter the prediction strategy is accomplished at the reducer phase by the deep neuro-fuzzy network classifier. The proposed method obtained the performance in terms of mean square error, root mean square error and mean absolute error with the values of 0.338 3, 0.581 7, and 0.391 5, respectively.展开更多

Ho...School decision makers are faced with a great many decisions when considering a school renovation or new school building. All stakeholders want a building that is safe and provides an optimal learning environment. However, it is often difficult to know which building features will have the greatest effect on student learning. Because of a limited understanding of the relationship between individual building features and student learning, researchers at the University of Oklahoma hope to explore how building components influence student and teacher performance. This paper explores the importance of school building features that can be designed and changed during a renovation project. The hope is to one day determine which features have the greatest impact on student test scores. The research team believes that although it is difficult to find the exact relationship between each building features and student outcomes with one study, if multiple users repeat the same or similar studies, hopefully we will one day know the effect of these building features. In order to develop feature building users survey and physical assessment tools, it was necessary for investigators to develop a list of important building features and their associated definitions in layman terms. This was accomplished through utilization and conducting of a CAB （community advisory board） and subject matter expert materials. In addition, previous research relating to different school building features and their associations with student performance were reviewed. To define and narrow the list the researchers, community educational, and building professionals rated based on their professional experience, how directly related each feature is to student performance. The building feature list serves as a starting point to determine which features should be analyzed in a later phase of the project. It is hoped that resulting tools based on the work of this project can be used by school decision-makers and researchers to access building features that have been identified through research as being important for student and teacher performance.展开更多

文摘Background:Despite increasing attention to parental educational anxiety in China’s educational system,the underlying mechanisms through which this anxiety affects adolescent academic performance remain unclear.This study aims to investigate how parental educational anxiety influences academic outcomes through depression and self-efficacy while considering the role of problematic social media use in today’s digital age.Methods:Data analysis was conducted using stratified random cluster sampling techniques.Participants for this study were recruited from middle and high schools in China.The sample comprised 2579 traditional two-parent families,each consisting of a pair of parents and one child.The commencement of data collection occurred in March 2024.A range of analytical techniques was employed to examine the relationship between parental education anxiety and student academic performance,including bivariate correlations,path analysis,mediation analysis,and moderation analysis.Results:The study findings revealed that parental educational anxiety negatively predicted student academic performance(β=−0.510,t=−35.011,p<0.001).Furthermore,a significant and negative relationship was identified between student depression and self-efficacy(β=−0.179,t=−8.336,p<0.001),which was chain-mediated.Additionally,problematic social media use moderated the relationship between parental educational anxiety and student academic performance(p<0.001),with stronger negative effects at higher levels of social media use.Conclusion:This study demonstrates that parental educational anxiety has both direct and indirect negative associationswith student academic performance through complex psychological pathways.The findings reveal a sequential mediation mechanism where parental educational anxiety first influences student depression,which in turn affects self-efficacy,ultimately impacting academic performance.The strength of these relationships is notably moderated by problematic social media use,with higher levels of social media engagement amplifying the negative association between parental educational anxiety and academic outcomes.These findings illuminate the complex interplay between family dynamics,student mental health,and educational achievement in the contemporary digital age.
文摘Learning challenges are more common in the 21 st century than many people believe; however, there are more efficient and better methods to develop academic learning skills for students. Identifying learning problems can help both students and lecturers to apply specific learning techniques and work together to be more productive in the process of teaching and learning. This study investigates the collaboration of science foundation lecturers in addressing the students＇ academic performance and challenges in their foundation modules at the University of Venda. The study is also aimed at finding out whether students can be able to apply their information technology （IT） skills in other modules and they make use of group work in projects into different foundation modules to enhance performance and develop academic learning skills. In this study, students were given projects in their respective modules （Foundation Biology and Foundation IT） and it was required to them to make use of their IT skills during the research report and also during the presentation of their project. These projects were done in groups wherein students undertook some mini researches. Their findings were then reported in writing and presentations were held. The Foundation English lecturer helped in assessing the use of the academic language used in writing and during oral presentations. The findings from these projects were that students＇ academic performance and skills improved and their specific knowledge in those modules also improved radically. It was found that group work plays a very imperative role in enhancing the students＇ performance and collaboration in various foundation modules.

文摘Analyzing and predicting the learning behavior data of students in blended teaching can provide reference basis for teaching.Aiming at weak generalization ability of existing algorithm models in performance prediction,a BP neural network is introduced to classify and predict the grades of students in the blended teaching.L2 regularization term is added to construct the BP neural network model in order to reduce the risk of overfitting.Combined with Pearson coefficient,effective feature data are selected as the validation dataset of the model by mining the data of Chao-Xing platform.The performance of common machine learning algorithms and the BP neural network are compared on the dataset.Experiments show that BP neural network model has stronger generalizability than common machine learning models.The BP neural network with L2 regularization has better fitting ability than the original BP neural network model.It achieves better performance with improved accuracy.
