Diversified Teaching Method in Basic Piano Course Instruction for Higher Education Teachers

Diversified teaching plays an important role in the sustainable development of China’s basic piano course instruction for higher education teachers.A diversified curriculum system should be designed to promote the development of each student,and efforts should be made to cultivate high-quality talents who can adapt to the various needs of the society as well as to promote the reform and development of basic piano course instruction for higher education teachers.The aim of this study was to explore the teaching of basic piano course for higher education teachers based on the diversified teaching method.The teaching methods use for basic piano course were analyzed in this study,and two research methods were used to carry out the present study so as to effectively improve the operation of the diversified teaching method.Through a survey of the current situation of piano instruction in two higher education faculties,we can see that the teaching of basic piano course in higher education is still dominated by the traditional teaching method although the majority of students preferred the diversified teaching method.

Diversified Teaching Methods in Nursing:Using Animal Experimentation to Promote Core Professional Competencies in Basic Nursing Training

Objective： The aim of this project was to train highly professional and specialized nursing students from medical colleges to adapt to bedside clinical care by exploring and discussing various methods of injection and IV infusion in animal experimentation to hone the core professional nursing competencies. Methods： Two classes from the 2012 senior graduating nursing class were randomly selected by a computer to conduct the diversified practical teaching methods based on animal experimentation. A hospital environment was simulated by requiring students to perform different types of injections and practical IV infusion techniques. A comprehensive evaluation of the core professional competencies, as well as other integrated competencies, was conducted to determine the effectiveness of the teaching methods. Results： Two-sampled, pairwise u-tests were performed between the scores of the experimental （nursing class 2） and control （nursing class 1） groups. These findings showed that the overall test scores were significantly higher in the experimental group compared to the control group and that the average P-values for the competencies in various categories were 〈0.01, which indicated statistically significant results. Conclusions： Based on the data from this project, diversified teaching methods for basic nursing training founded on animal experimentation can help nursing students perfect their core professional competencies and improve their overall professional standing. The introduction of animal experimentation requires further verification, and an increased acknowledgement of its benefits through the widespread dissemination of this information.

Research on the Application of Diversified Teaching in Gynecological Clinical Teaching

At present,the main body of clinical teaching in obstetrics and gynecology is still the traditional clinical teaching method,in which clinical teachers are the main body,and interns are the passive.It is not conducive to giving full play to interns'learning enthusiasm and ability to actively solve problems if lack of stimulating the clinical thinking and cultivating the ability to raise questions.In the face of the problems and deficiencies in gynecological clinical teaching in the new era,our team tries to adopt diversified teaching methods,such as medical record teaching method,multimedia teaching method,main-role teaching method,problem-based learning teaching method and so on,so as to improve students'ability of autonomous learning and problem-solving,as well as students'ability of innovation and cooperation.Therefore,clinical teaching teachers and teaching managers should keep pace with the times to carry out diversified teaching mode reform in gynecological clinical teaching.

Helping consumers to overcome information overload with a diversified online review subset

Redundant online reviews often have a negative impact on the efficiency of consumers' decisi on-making in their on line shopping.A feasible solution for business analytics is to select a review subset from the original review corpus for consumers,which is called review selection.This study aims to address the diversified review selection problem,and proposes an effective review selection approach called Simulated Annealing-Diversified Review Selection(SA-DRS)that considers the semantic relationship of review features and the con tent diversity of selected reviews simultaneously.SA-DRS first constructs a feature taxonomy by utilizing the Latent Dirichlet Allocation(LDA)topic model and the Word2vec model to measure the topic relation and word context relation.Based on the established feature taxonomy,the similarity between each pair of reviews is defined and the review quality is estimated as well.Fin ally,diversified,high-quality reviews are selected heuristically by SA-DRS in the spirit of the simulated annealing method,forming the selected review subset.Extensive experiments are conducted on real-world e-commerce platforms to demonstrate the effectiveness of SA-DRS compared to other extant review selection approaches.

Optimal operation of electricity, natural gas and heat systems considering integrated demand responses and diversified storage devices

In recent years, the increasing penetration level of renewable generation and combined heat and power(CHP) technology in power systems is leading to significant changes in energy production and consumption patterns. As a result, the integrated planning and optimal operation of a multi-carrier energy(MCE) system have aroused widespread concern for reasonable utilization of multiple energy resources and efficient accommodation of renewable energy sources. In this context, an integrated demand response(IDR) scheme is designed to coordinate the operation of power to gas(P2 G) devices, heat pumps,diversified storage devices and flexible loads within an extended modeling framework of energy hubs. Subsequently, the optimal dispatch of interconnected electricity,natural gas and heat systems is implemented considering the interactions among multiple energy carriers by utilizing the bi-level optimization method. Finally, the proposed method is demonstrated with a 4-bus multi-energy systemand a larger test case comprised of a revised IEEE 118-bus power system and a 20-bus Belgian natural gas system.
