For a successful software project, accurate prediction of the cost, time and effort is a very much essential task. This paper presents a systematic review of different models used for software cost estimation which includes algorithmic methods, non-algorithmic methods and learning-oriented methods. The models considered in this review include both the traditional and the recent approaches for software cost estimation. The main objective of this paper is to provide an overview of software cost estimation models and summarize their strengths, weakness, accuracy, amount of data needed, and validation techniques used. Our findings show, in general, neural network based models outperforms other cost estimation techniques. However, no one technique fits every problem and we recommend practitioners to search for the model that best fit their needs.展开更多

Giving priority to learning is to highlight students' initiative in learning, students' happiness in learning and students' effectiveness in learning. The mixed teaching mode is the combination of the current online teaching mode and the traditional teaching mode under the class. Teachers have changed their role from "teaching" to "learning" as a guide and helper, making full use of online teaching to solve the problem of difficult or ineffective explanation of knowledge points or technical actions in traditional teaching. The mixed teaching mode creates a platform for students to learn independently, and releases more practice time for offline teaching at the same time, which makes them complement each other well online and offline, thus comprehensively improving the quality of outdoor sports courses and students' learning effect.展开更多
