Factors Affecting Selection of Elective Courses:The Use of Multi-Criteria Decision Making Model

Elective course selection has always been a serious and important decision making process for students in institutions. The aim of this study is to determine weights of factors affecting elective course selection from students' perspective. So as to solve the problem, Analytic Hierarchy Process (AHP) based model was used. Factors which affect the elective course selection from students' point of view include five main criteria and 13 sub-criteria which were indicated by students. An online questionnaire containing demographic questions, enabled each student to compare the relative priority of criteria with all of the other criteria. The responses were evaluated via Super Decisions software, and priorities were determined using the Analytic Hierarchy Process (AHP). According to the analysis of 40 experts (i.e., graduate students studying in engineering programs), course schedule and teaching staff related factors are the two most important factors affecting the elective course selection. A real- life situation which will help students who are indecisive and hesitates while selecting an elective course was observed. AHP contributes to develop an analytic and comprehensive framework decision making. The method should be considered by faculty member involved in decisions about curriculum update and offering new courses.

Molecular mapping of a novel wheat powdery mildew resistance gene Ml92145E8-9 and its application in wheat breeding by marker-assisted selection

Powdery mildew, caused by Blumeria graminis f. sp. tritici(Bgt), is one of the most devastating diseases of common wheat(Triticum aestivum L.). The wheat line 92145 E8-9 is immune to Bgt isolate E09. Genetic analysis reveals that the powdery mildew resistance in 92145 E8-9 is controlled by a single dominant gene, temporarily designated Ml92145 E8-9. Bulkedsegregant analysis(BSA) with simple sequence repeat(SSR) markers indicates that Ml92145 E8-9 is located on chromosome 2 AL. According to the reactions of 92145 E8-9,VPM1(Pm4 b carrier), and Lankao 906(PmLK906 carrier) to 14 Bgt isolates, the resistance spectrum of 92145 E8-9 differs from those of Pm4 b and PmLK906, both of which were previously localized to 2 AL. To test the allelism among Ml92145 E8-9, Pm4 b and PmLK906, two F2 populations of 92145 E8-9 × VPM1(Pm4 b) and 92145 E8-9 × Lankao 906(PmLK906) were developed in this study. Screening of 784 F2 progeny of 92145 E8-9 × VPM1 and 973 F2 progeny of 92145 E8-9 × Lankao 906 for Bgt isolate E09 identified 37 and 19 susceptible plants, respectively. These findings indicated that Ml92145 E8-9 is non-allelic to either Pm4 b or PmLK906. Thus, Ml92145 E8-9 is likely to be a new powdery mildew resistance gene on2 AL. New polymorphic markers were developed based on the collinearity of genomic regions of Ml92145 E8-9 with the reference sequences of the International Wheat Genome Sequencing Consortium(IWGSC). Ml92145 E8-9 was mapped to a 3.6 c M interval flanked by molecular markers Xsdauk13 and Xsdauk682. This study also developed five powdery mildew-resistant wheat lines(SDAU3561, SDAU3562, SDAU4173, SDAU4174, and SDAU4175)using flanking marker-aided selection. The markers closely linked to Ml92145 E8-9 would be useful in marker-assisted selection for wheat powdery mildew resistance breeding.

Grain selection and growth orientation of prior-β phase for Ti-6-4 during additive manufacturing:insights from a modeling perspective

The microstructure of Ti-6-4 components produced by additive manufacturing suffers from the coarse and elongated prior-β grain,which leads to a decrease of the tensile behavior and the occurrence of anisotropy.To understand and control the grain evolution,a multiscale simulation is applied to investigate the relationship between the grain selection,growth orientation,and the molten pool morphology with the different deposition layer numbers and processing parameters.The accuracy of the simulation is validated by experiments in both qualitative and quantitative ways.Results show that when the grain with unfavorable orientation loses the competitive growth with its neighbors,there will be a great chance that the blocked grain is eliminated in the following layer-and-layer deposition,which leads to the increase of the grain width.The size of the molten pool increases remarkably as the layer number increases,which lays a heavy burden on the stability of the molten pool.The analytical relationship between the molten pool morphology and the grain growth orientation is also deduced.The flat molten pool causes the grains with the <001> direction close to the building direction to have greater survival potential.Besides,decreasing the line power energy shows little effect on the stability of the molten pool and the grain growth orientation,especially when the deposited layer number is large.The revealing mechanisms will help in understanding and further controlling the grain evolution.

On the Selective Online Course of Campus English

Online learning is becoming more and more popular among college students.College courses are going online recently but seldom have a systematic structure.In an attempt to testify the effect of online learning of the English language,a research is carried out by running a selective course of Campus English online.The whole process of the course is running online.A Wechat group is set up for the purpose of supervision.Each unit has an assignment to follow.Through finishing these assignments,the skills of listening,speaking,reading and writing are all practiced.To test the students’learning outcome,the instructor only needs to check their assignments.Feedback is offered to the students as soon as the teacher has corrected the assignments.After the twenty-class-hour learning,a survey is carried out to find out the student’s further needs and satisfaction level.The result of the survey shows that the students are quite satisfied with this form of online learning.Some advice is also offered by them to contribute to the further improvement of this online course.This research has shed some light on further improvement of online course.

Study on college English elective courses

College English Curriculum Requirements poses a great challenge for college English teaching. One way to deal with the status quo is to offer selective courses to non-English majors. This article gives an early probe into the rationale on a new course-designing practice as well as a detailed introduction to an illustrative course. As proved, the attempt to practice selective courses is feasible and effective for individualized teaching and integrated language competence cultivation.

The Construction of"Integration"of Ideological and Political Course in Primary and Middle Schools in the New Era:Value Connotation,Dilemma Analysis and Path Choice

The ideological and political course in primary and secondary schools is the key course of comprehensive education and the“integration”construction of the ideological and political course in the new times is an important way to solve the problem of the culture how to train and cultivate the fundamental problem.At the same time,it also helps to form the construction pattern of the cultural development in the ideological and political class of the middle and primary schools in the new era.In the course of the“integration”construction of the ideological and political course of the primary and secondary schools the course of the construction of the“integration”course of the ideological and political course of the primary and secondary schools still faces the separation of the rational and political rupture of the curriculum system the communication and cooperation of the teaching staff,the separation of the course theory and the practice,and the“integrated”of the“systematize”of the ideological and political course in the new era needs to be Course Mode“unification”and the like The path achieves a breakthrough.It provides a useful attempt to better grasp and understand the“integration”construction of ideological and political course in primary and secondary schools in the new era.

英语教育硕士课程设置的问题与对策研究

目前,我国的英语教育专业硕士点和招生人数众多,但较少学者对英语教育硕士的培养展开研究,而课程设置是关涉硕士培养质量的最关键因素之一,因此,以“双一流”高校和普通地方性高校的英语教育硕士课程为例,探究课程设置的问题与对策。研究结果显示:英语教育硕士课程设置存在不同层次高校之间的课程资源分布不均衡,教育哲学类、专业选修类和前沿性课程不多等问题。鉴于此,各院校可采取跨校选课或外聘任课教师的措施,并且增设教育哲学类、专业选修类和前沿性课程。

中外混合式教学质量评价标准比较研究
