Experiential Learning with Internal Audit Service Projects： Students＇ Perceptions

Students are very familiar with their own universities and also are interested in improving their alma maters. The purpose of this research is to share insights about a project that can be used for both traditional Auditing courses and the Internal Auditing course. The project requires that students ＂audit＂ certain elements of the universities＇ non-confidential finances as well as perform operational and compliance techniques. The project creates synergy for experiential learning and improvement of university operations. Examples of educational issues that were improved with the operational audits are： （1） better information posted for office hours and class times; （2） better scripting for professors＇ and staff＇s voicemail messages; and （3） campus safety improvements. The students also seemed more enthusiastic about auditing and happy to contribute to the excellence of their university.

Evaluation of Reported Statistical Inferences

Someone or the other is always pointing to a published study to justify a point of view or the need for a change in what we do or how we live. There are so many such studies, many reported in top-notch journals, reporting results inconsistent across and often inconsistent within. It is in the interest of increasing the credibility of science, and to safeguard the general public living with its overt and covert influence, to filter good science from bad. Some inferences are good, even when counter-intuitive or seemingly inconsistent, and are likely to withstand scrutiny and some others may represent marginal effects in the aggregate not entirely useful for individual choices or decisions, and are often non-reproducible. The New York Times featured an article in August 2018 debunking some of the reported studies supporting testing for Vitamin D deficiencies and the recommendation of large supplemental doses of Vitamin D. Some of these Vitamin D claims, among other claims, were reported as not holding up on replication in controlled trials [1]. We have noted in Ref. [2] that we need to be wary as individuals about reported signals detected in studies using stochastic data, even when these aggregate signals are of a large magnitude. We demonstrated discordance rates of 30% or higher between subject level assessments of effect and the conclusion drawn in the aggregate. Here we will provide a computation of this discordant proportion as well as post-hoc assessments of aggregate inferences, with emphasis on evaluating studies with time-to-event endpoints such as those in cancer trials. Similar evaluations for continuous, binomial data and correlations are also provided. We also discuss the use of response thresholds.

Evaluation of an Examination in Biochemistry and Molecular Biology

This work was aimed at assessing one of the examinations applied to the students enrolled in courses of Biochemistry and Molecular Biology at the School of Medicine, UNAM. We analyzed a f＇mal examination in this subject. The test consisted of 80 multiple choice questions. The database was exported to Excel and then to the SPSS 16 statistical software for statistical analyses. The following techniques were used： （1） dificulty index （Pi）, （2） discrimination index （Di）, （3） discrimination coefficient （rpbis）, and （4） Cronbach＇s alpha. Those questions that complied with 3 of the 4 mentioned techniques were considered acceptable; of the 80 questions, only 25 were accepted corresponding to 31%. The topic with the largest number of accepted questions was Water and pH （75%）, and the topics without accepted questions were Bioenergetics and Hormones （0%）. It is recommended that the faculty members that elaborate multiple choice examinations must know the subject, and should have a formation in didactics and educational methodology.

Empowering Students with Practical ＂Working＂ Experience through Hands-on Multidisciplinary Design Projects

One of the problems that many engineering graduates face when looking for their first job is： Do you have experience？ Employers prefer graduates with relevant experience to those without. Why is experience so important to employers？ Can students accumulate ＂working＂ experience while studying in college？ This paper discusses the use of design projects inside and outside of classrooms to help students gain ＂working＂ experience and skills through hands-on design activities that simulate the actual design activities that occur in the industry. Faculty members from the Mechanical Engineering Technology and Computer Engineering Technology departments were involved in creating multidisciplinary design projects. The design projects give students new insights into what they learn in their coursework and pro.vide students the valuable experiences in analytical skills, concurrent engineering approach, people skills, and management skills needed for the students when looking for employment.

Research on the Inevitability of Soccer Teaching Reform in Colleges and the Optimization

The soccer is an extremely universal movement that has received populace’s affection, natural, the soccer teaching also entered university’s classroom that becomes in the university physical education the important constituent. Speaking of the university students, the soccer is not merely the simple sports project which may help the student more importantly to build up strength the healthy body, enriches own after school life, therefore has received the general university student’s affection, moreover the soccer also has the unique charm, it has the oneself quite obvious characteristic in the sports, for instance its grouping development, location request and so on, these all deep attraction student vision, simultaneously also have been receiving the social people from all walks of life’s widespread attention. Nowadays, in the physical education curriculum of colleges and universities, the teaching of students’ football is mainly the knowledge and skill of soccer, ignoring the cooperation between the students. This traditional teaching mode cannot adapt to the teaching reform and quality education The implementation of physical education teachers in the teaching of football has been controversial and questioned, this is all the college physical education teachers face new challenges and new problems. This paper mainly analyzes and discusses the problems existing in college football teaching, aiming at these problems puts forward the corresponding reform measures and optimization strategy, and hope to provide certain reference for the development of football teaching in colleges and universities.

Mechanical Design and Students＇ Creativity ＂Think outside the Box＂

A design project was used in junior level mechanical design course to challenge the students＇ creativity skills. Beside the theoretical foundation of the course subject, the students were introduced to several professional skills such as： decision making tools, technical review meetings, interaction with customers, and teamwork skills. The design challenge was to develop a bike rack to meet a list of technical and marketing constraints. Details of the project requirements are presented with a brief overview of the main project mentoring tools. Students＇ creativity is discussed through two samples of the student work. It was noticed that, the basic creativity skills of the students can be improved by using some of the training tools, however, the students vary in their response to this training.

Research on the development of the natural tourism resources in the countryside based on the perspective of the ecological aesthetics

The cartier that the natural tourism projects rely on should be the objective natural environments, including the mountains, water, animals and plants and so on, which are the object present before the development of the project. Therefore, what the natural tourism projects should first be ＂the economic value of the natural resources＂. However, after the man-made planning and being given the humanity, they have the ＂economic value of the human resources＂. In the construction of the future path of the development, we should also have the dynamic study on the subjective preferences of the Chinese consumers. The change of these subjective preferences directly results from the change of the levels of their own income.
