高职数学教学必须加强数学思想方法的教学

数学思想方法是数学知识的核心,是数学的精髓和灵魂,是研究数学理论和运用数学解决实际问题的指导思想。本文针对目前高职数学教学中存在的数学思想方法教学重视不够以及教法上随意性的现状,提出通过加强数学史和基本数学思想方法的介绍,以及倡导“问题解决”的教学模式来提高学生的数学素养。     

联系生活实际,解决数学问题

小学数学教学必须从学生熟悉的生活情境和感兴趣的事物出发,为他们提供观察和操作的机会,使他们能够从周围熟悉的事物中寻找更多的数学题材。学生联系生活实际学习数学、理解数学、应用数学,就会体会到数学就在他们身边,认识数学的作用,感受数学的魅力。     

浅析高职数学教学中的人文精神及其培养

目前在高职高专数学教育中存在着只注重数学知识、数学思维、数学思想的研究和教学的现象，而数学教学中应体现的人文精神却常常被忽视了。本文分析了数学教学中蕴涵的人文精神，并提出应坚持自觉性与渗透性的原则，加强数学教学中人文精神培养。     

OTBL模式在数学应用能力培养中的实践——以市场营销专业为例

OBTL模式是以明确的目标和成果为导向,以学生为中心,以培养学生适应未来岗位要求的能力和素质为根本目的的教育模式。借鉴OBTL教学模式及其理念,依据市场营销专业的人才培养目标,确立了数据处理能力、案例分析能力和数学建模能力的能力目标,设计相匹配的多种数学实践活动,并构建多元化评估体系,旨在增强教学的针对性和实效性,提升高职学生的数学应用能力。     

高等数学概念教学的探索

概念教学是数学教学的核心.但是,高等数学中概念众多,并且又都包含着运动、变化等辨证观点,对于习惯于按静止观点学习初等数学的"大一"新生来讲,理解和掌握这些数学概念确有一定的难度.因此,在教学中要重视概念的引入,揭示概念的本质,加强概念的应用,将数学知识与专业知识紧密联系起来.

REGIONAL WATER SUPPLY PLANNING BY INTERACTIVE SYSTEMS ANALYSIS1

Abstract: This paper describes an interactive data and model generator that is intended to bridge the gap between the water resource enginner and planner and the mathematical progrmming systems approach to regional water supply planning. The optimization objective is to minimize total annual cost with respect to capital investment and operation and maintenance costs. The matrix generator formulates the necessary hydrologic, demographic and programming problem for system optimization. The interactive program guides the user through the input and optimization segments, totally eliminates the chore of manually structuring the model matrix aides in eliminating errors, and allows use by planners without skill in mathematical programming.     

THE PRACTICE OF COMBINED SEWER SYSTEM MODELING1

ABSTRACT: A combined sewer system is a complex system subject to the dynamic stimuli of precipitation, runoff pollution loads, and sanitary wastes. The system response is a random series of pollutant loads to a receiving water. In many localities, these discharges create considerable water quality problems. Mathematical models can and have played a useful role in predicting the behavior of combined sewer systems and evaluating abatement strategies. Based on the authors' experiences over the past several years, this paper explores some of the positive and negative aspects of using deterministic mathematical models to simulate the behavior of combined sewer systems. A case study follows a discussion on modeling objectives, limitations of modeling, model selection, establishing model credibility, and many other considerations necessary in modeling and simulating these systems.     

NUMERICAL TECHNIQUES APPLIED TO PARTICLE DEPOSITION DURING SLOT FLOW1

ABSTRACT A mathematical model is presented of the process of particle sedimentation from a fluid-solid slurry while flowing through a vertical slot. The differential equations describing the process consist of 1st order, non-linear, partial differential equation and a 1st order, ordinary differential equation. These two equations have been solved using a forward difference technique. Results for typical sets of system parameters are presented and discussed. The model finds practical application to solid-waste disposal processes and to petroleum reservoir stimulation processes.     

UTILIZATION OF MODELS IN WATER RESOURCES1

ABSTRACT: A 1984 survey of water resources personnel was conducted to determine the current and future uses of mathematical models in planning, design and operations of water resources systems. Eighty-six percent of those responding indicated they have used mathematical models in the last year. Lack of appropriate data, inadequate time and funding to do the modeling and lack of models that represent the “real world” situation were the most frequently mentioned constraints to model use. Microcomputers were seen as having a positive influence on mathematical model use in water resources.

THE DEVELOPMENT OF A MODEL TO EVALUATE HYDROLOGIC RISK IN WATER RESOURCE SYSTEM DESIGN1

In this paper, a procedure for analyzing a water resource system with special emphasis on evaluation of acceptable economic risk due to occasional failures to deliver water is proposed. The basic methodology includes the development of a simple mathematical model which describes the physical hydrologic and economic characteristics of a single reservoir irrigation and city water supply system and an evaluation of economic benefits of the system with full and partial deliveries of water. The system is simulated for various combinations of decision variables (system magnitudes) and an optimum design is obtained by response surface technology. Emphasis is placed on the basic model and methodology although, in order to introduce some realism, the procedure is applied to data based on the existing reservoir system on the South Concho River in West Central Texas.
