PGDnet: a new problem‐solving virtual learning environment

The purpose of this paper was to provide information about the virtual learning environment known as PGDnet (the Spanish acronym for Plataforma de Gestión Docente or Educational Management Platform in English), which was developed by the innovative education group at the Technical University of Madrid known as “Nuevas metodologías docentes en ingeniería mecánica y fabricación” (New Teaching Methodologies in Mechanical Engineering and Manufacturing). This tool has been created on an ad hoc basis to cover specific teaching requirements for some engineering courses, which would be difficult to implement on general educational platforms such as Moodle or Blackboard. PGDnet was essentially created as an online engineering problem‐solving tool. These exercises are checked and corrected automatically, providing students with their final and partial scores, and with the solutions to these various sections. A stochastic programming model selects different exercises each time that an activity is performed and attaches the tables, graphs, figures and annexes that are needed for their resolution in each case. As is common with these types of tools, PGDnet provides effective management of publication and delivery dates for the proposed work, and contains records and databases, which allow the stored information to be processed. Its main features include ease of use, reliability and great versatility as a specific tool in the area of technical university education.     

Students’ conception of infinite series

This is a report of a study of students’ understanding of infinite series. It has a three-fold purpose: to show that students may construct two essentially different notions of infinite series, to show that one of the constructions is particularly difficult for students, and to examine the way in which these two different constructions may be built so that we may uncover ways to help students improve their understanding. The theoretical framework consists of action–process–object–schema theory and the specific model of conceptions in Balacheff’s theory of conception, knowing, and concept. Approaching the problem from these two different theoretical perspectives allows us to provide different and at the same time complementary explanations of observed phenomena. The two different infinite series constructions are, briefly stated, series as an infinite unending process of addition and series as a sequence of partial sums. Students are found to have difficulty building an understanding of series as a sequence of partial sums and thus tend to have difficulty in problem situations that require this interpretation. The study uses semi-structured interviews with 10 graduate students. The interviews explore situations that might give insight into students’ notion of the sequence of partial sums.     

歌词创作中设问运用的语言艺术

对于歌词里经常运用的设问修辞格,根据问句与答句的接续形式的不同,分为单问单答、单问连答、连问单答、连问连答四种类型,可集中明显地认识设问在歌词创作中的普遍应用和广泛体现。设问在歌词创作上具有兴波助澜,引人思索的语言艺术功能,用得好,能引起人们的注意,诱人思考,使演唱的内容变得更加吸引人。     

社会转型期大学生感恩教育探析

完善我国民办高校会计核算制度的对策

当前,我国民办高校会计核算存在诸多问题,改革势在必行。民办高校会计制度构建应遵循教育规律并关注自身的特点,应严格营利性与非营利性分类管理与核算,采用权责发生制、真实反映资产、合理核算成本、正确处理"合理回报"、基建会计主体一体化、建立一套全新的财务报告体系。     

A Case Study on the Use of Blended Learning to Encourage Computer Science Students to Study

Students tend to procrastinate. In particular, Computer Science students tend to reduce the number of hours devoted to study concepts after class. In this paper, a case study on the use of Blended Learning to encourage Computer Science students to study is described. Furthermore, an experiment in which the reaction of 131 Computer Science university students to the proposal is analyzed. The material for the preparation of an exam was produced both in electronic and paper formats. 64 students were asked to study using a free-text scoring system, and 67 students were asked to study with printed documentation in the same class. The students’ reactions, the results of a pre-post-test and the answers to a voluntary and anonymous satisfaction questionnaire were registered. After that, students were given the option to keep studying with the scoring system or with the printed documentation. 99% of the students chose to study with the computer, and a higher frequency of study was registered during the previous month to the exam.     

内江旅游发展现状、问题及对策

近年来内江旅游发展取得了长足进展,但相对于四川其它市州仍较落后．文章通过广泛深入的考察、调研和资料分析,认为内江旅游发展主要存在资源开发粗浅,发展方式粗放,基础设施滞后,宣传促销乏力,区域合作不足,旅游发展氛围不浓,产业体系尚未形成等问题．有鉴于此,文章进一步分析了内江旅游发展存在的优势与机遇、劣势与挑战,提出了恰当定位旅游目的地性质,鲜明塑造旅游形象,深度整合旅游资源,打造精品寻求引爆点,完善旅游基础设施和配套设施,加强旅游商品开发和宣传促销等一系列进一步促进内江旅游发展的对策与措施．
