  • Continual Improvement Assessments Based on the ABET Accreditation Process: Overcome Challenges Implementing Management System   Order a copy of this article
    by Abdel-Rahman Al-Qawasmi, Abdullah Almuhaisen, Iskander Tlili 
    Abstract: Reducing the unemployment rate, achieving economic growth and bridging the gaps between industries needs and engineering graduate skills, are the three long-term drivers of engineering education performance which are becoming gradually competitive. To overcome the engineering education weakness issue, different approaches are being considered including programs accreditation to have the greatest potential within engineering education. Recently, decision makers and researchers reconsider assessment and improving engineering accreditation process using different management tools. In this study a new management materials based on quality standard of National Commission for Academic Accreditation and Assessment (NCAAA) and Accreditation Board for Engineering and Technology (ABET) was developed and tested. Results have shown a noteworthy improvement on the performance of faculty assessment courses and on the overall quality process. The present work demonstrates that the proposed quality management system (QMS) contributes to a substantial decrease of waste of time made by faculty member to organise and assess their course along the entire semester and an increasing percentage around 60 per cent of faculty member involved in continuous quality improvement through proposed QMS.

  • Geometrical Tools to Teaching Azeotropy Using Simplified Thermodynamic Models   Order a copy of this article
    by Gustavo Platt, F.S. Lobato, F. D. Moura Neto, G.B. Libotte, D.A. Goulart 
    Abstract: In this work we propose a geometric view of the azeotropy problem, using some simplified models. We demonstrate that the occurrence of azeotropes in binary mixtures can be viewed - geometrically - as the intersection of curves in the plane (for some models, these curves are parabolas). Furthermore, the idea of functions from the plane to the plane is used to understand the azeotropic phenomenon. These ideas are illustrated with two simple cases, with one and two azeotropes, allowing the analysis of a nonusual thermodynamic behavior -- such as double azeotropy -- with simple mathematical tools, by undergraduate students in Chemical Engineering courses.

  • Student-Parent Teams: A 10-Year Retrospective Study of an Undergraduate Research Experience   Order a copy of this article
    by James Giancaspro, Nam Ju Kim 
    Abstract: The objective of this study was to investigate the long-term (10-year) impact of a small, yet unique, outreach effort where three teams of undergraduate students were paired with their parental counterparts to conduct civil engineering research supported by the United States' National Science Foundation. Those students are compared to a control group of undergraduates who participated in a traditional research experience and were exposed to the same conditions and research project. A survey instrument was used to collect data related to the participants' actual career path trajectory, self-efficacy, scholarly productivity, and parental influence in their decisions for postgraduate education and career planning. Parental support for students' postgraduate plans either remained unchanged or increased following the research experience. While the participants in the student-parent teams produced more scholarly products than the control group in the decade following the experience, the sample size is too small to draw causal inferences.

    by Jue Wang, Xi Chen, Yang Zhang 
    Abstract: In order to improve students classroom learning effect, the influencing factors of communication ability were analysed. The traditional method of analysing students classroom ability neglects the ordering of classroom communication ability factors, which results in poor fitting effect and high CPU consumption. This paper proposes an analysis model of influencing factors of students classroom communication ability based on support vector machine. The sample data were converted and cleaned to establish a SVM model for influencing factors and students classroom communication ability. The trained SVM model was used to analyse the degree of influence of each factor on students classroom communication ability, and the factors were ranked in importance, so as to clarify the influencing factors of students classroom communication ability. The simulation results show that the prediction results obtained by the research method are close to the fitting curve of the actual results. The CPU consumption of system operation is 15.88 Hz, which is lower than the traditional method.

  • Expectations for cooperative instruction supported by the Internet+Employment platform in work placement practice   Order a copy of this article
    by Xifeng Liao 
    Abstract: Close high-quality cooperation between a workplace employer and the college is a prerequisite for effective training of students in vocational education. Therefore, the researcher adopted the internet+employment platform as a typical case to analyse its main supportive functions for work placement instruction. Descriptive data analysis was employed to study the expectations of both vocational students and workplace supervisors for the cooperative teaching supported by the platform. The case study showed that the platform was weak in several areas such as in sharing teaching resources to facilitate employer-college cooperation. The results of the data analysis suggested that most students and workplace supervisors have a thorough understanding of the importance of closer cooperation and cooperative assessment by both the employer and the college. However, the expectations of the students and workplace supervisors were different in seven aspects. Among them, the students did not expect much cooperation that would lead to a closer monitoring of their work positions, and the willingness of the workplace supervisors to cooperate with college advisors in the use of cloud technology was quite limited. Suggestions for future development of the internet+employment platform were proposed. Combining the functions of this platform with those of other cloud platforms might support better employer-college cooperative instruction.

    Abstract: In order to overcome the problem that students’ learning behaviour process is easy to form misclassification in the process of serial classification, this paper proposes a method to detect students’ learning behaviour in class based on parallel classification algorithm. The parallel classification model is constructed. By measuring Kinect coverage and adjusting Kinect top view angle, the coordinates of each student’s position are transformed. The auxiliary feature vector is applied in behaviour recognition to realise the parallel combination and processing of multiple data sources, accurately extract the feature vector to form different relevance, and realise the detection of students’ classroom learning behaviour. The experimental results show that students can grasp the degree of interest in the course and the degree of seriousness in the whole teaching process. The detection rate is more than 90%, which is practical.

    by Mei Liu, Shusheng Shen, Changsheng Chen 
    Abstract: For better adapting the course to different learners' needs, this study analysed the learners' online learning behaviours. Through using data mining technology to mine the learning behaviours from five dimensions: video watching, text reading, discussion and communication, test and assignments taking, we draw the following conclusions: the demographic characteristics of learners show that the learners are mainly composed of principals, middle-level educational managers and key teachers. The learner's general learning behaviour characteristics are mainly expressed by the facts that the learners' interest in practical cases, and few participants can last more than four weeks, and the learners like videos and texts but they do not like to speak in the discussion forum. Learners can be divided into three clusters: certificate-oriented learners, practice oriented learners and browsers. The value of MOOC should not be evaluated on the basis of certification rates but on whether the learner's learning needs are met.

  • Evaluation of learners' online learning behaviour based on the analytic hierarchy process   Order a copy of this article
    by Xuejiao Huang, Xiaojin Wang, Fengjuan Liu 
    Abstract: The online learning behaviour has become an important factor in predicting the learning achievement. Evaluating online learning behaviour is one of the hot topics in the field of IT education, but does not carry out specific weights and score distribution. Therefore, the online learning behaviour data from the 'Moso Teach' cloud platform was analysed by correlation analysis, cluster analysis and analytic hierarchy process analysis. We found that problem-solving behaviour of learners is the least, which is not common in online learning behaviour, while social interaction behaviour is better than problem-solving behaviour, and resource learning behaviour is the most common in online learning. The score distribution diagram of resource learning behaviour shows an inverse s-shaped curve, while the curves of the score distribution diagram of social interaction behaviour and problem solving behaviour are close to a straight line. There are learning achievement differences in resource learning behaviour and problem-solving behaviour, and core-marginal differences in resource learning behaviour and social interaction behaviour.

    by Jinan Jia 
    Abstract: Studies on e-learning behaviours of undergraduates are of great significance to improve the quality of e-learning. With e-learning behaviours in the course cross-cultural communications offered for students majoring in International Economy and Trade of the International Scholarly Exchange Curriculum (ISEC) program launched by an ethic university in China as the object, this paper collects students' e-learning behaviour data during the learning process and concludes that there is strong utilitarian element and weak interactivity with e-learning. Students lack the awareness of reflective learning. There is significant difference in learning hours among students, with a considerable portion of the hours being allocated to homework. Content of courses on the e-teaching platform is not pertinent. This study provides suggestions to improve e-learning behaviours of undergraduates in terms of course resources, external and internal monitoring of e-leaning, teacher-student interaction and assessment system optimisation. E-learning environments should be improved and more online courses should be provided. External and internal monitoring over e-learning should be enhanced to foster independent learning capabilities. Communications between students and teachers should be encouraged to better the e-learning quality.

    by Qiyun Wang 
    Abstract: Blended synchronous learning (BSL) has the potential to combine the advantages of classroom instruction and online learning. In this study, BSL was designed and implemented from the pedagogical, social, technical, and managerial aspects. This paper presents how BSL was prepared and designed before a lesson, implemented during the lesson, and improved after the lesson from the instructor's perspective. The results showed that the instructor needed to adjust certain learning activities before a lesson. He was often cognitively overloaded and having difficulties in monitoring the participation and engagement of the online students during the lesson. The design and implementation of BSL was gradually improved through reflections after the lesson. Implications for teachers who intend to apply this approach are discussed.

    by Suzhen Li 
    Abstract: In order to solve the problem that teachers cannot monitor learners' learning behaviour or evaluate learners' learning objectively and scientifically because of the relative separation of time and space between teachers and students, covering Bayesian network learning evaluation model based on knowledge relationship is proposed. The information related to students can be divided into two parts: domain-related information and domain-independent information. Firstly, the modelling of domain-related information is mainly discussed. The process of domain-related information modelling is the Bayesian networking process of the courses that students have learned. Secondly, the time and space complexity of the algorithm is reduced by simplifying the network structure and optimising the order of node deletion in the triangulation process. The results show that the model can accurately judge the degree of students' mastery of knowledge, and can provide students with personalised guidance strategy.

    by Xin Li, Tong Zhou 
    Abstract: The objective of this study is to design an academic warning system to identify students with abnormal learning behaviours, to give early warning of students' learning status, and to help students successfully complete their studies. In this study, the comprehensive academic performance of university students is taken as the research object, and the basic information data, academic performance data, and online data are collected. After analysing the students' learning behaviour, an online learning warning system is constructed based on grid based on clustering by fast search and find of density peaks (GBCFSFDP) algorithm, and the system is divided into dynamic warning and static warning. It found that the clustering of students' learning behaviour completed by GBCFSFDP algorithm can be divided into six specific categories, and the attributes that influence the learning performance can be differentiated by weighted naive Bayes classification algorithm based on fruit fly optimisation algorithm (WNBC-FOA). The results show that the time spent online have the greatest impact on students' performance. Therefore, this online learning early warning system can make it easier for students and teachers to understand the reasons for learning abnormalities and the correlation between different behaviours and academic performance, so as to make corresponding improvements.

    Abstract: K-means clustering algorithm is used to analyse plenty of learners' behaviour data stored on the online learning platform. The learning behaviour data, basic information, and user types and factors affecting performance of online learning learners are firstly analysed and explored. Secondly, based on feature selection and optimisation algorithm of initial clustering centre, a K-means feature selection algorithm is proposed, and an equilibrium discriminant function is presented to balance the difference between the clusters and within the clusters. Finally, the clustering centre obtained by K-means feature selection algorithm is used as the centre of the neural network. The parameters, input and output variables of the prediction model are set. Based on the radical basis function (RBF) neural network structure, the performance prediction model is constructed, which dynamically updates to enable accurate performance predictions. The results show that the performance prediction model proposed has high prediction accuracy for online learners' performance.

  • Adaptive optimisation algorithm for online teaching behaviour   Order a copy of this article
    by Jinhua Zhu 
    Abstract: It is believed that there are two mechanisms, namely, the mechanism of mutual learning among multiple teachers and the mechanism of adaptive step size improvement, to optimise teaching learning-based optimisation (TLBO) algorithm. Firstly, by setting up multiple teachers to teach in the TLBO algorithm, the diverse nature of the population can be preserved. The algorithm is improved in the precision of optimisation, and the algorithm is improved on the weakness of local optimisation. The student's learning step size is a random value in the standard algorithm, which neglects the fact that the student's progress speed changes continuously with own state. Adjusting the student's own state is an improved learning step, which can improve the accuracy of the algorithm. The results show that the improved algorithm has faster convergence speed and higher solution precision, so the improved algorithm is superior to TLBO in solution accuracy, stability and convergence speed.
