System Development of Science Learning through Multimedia Network enforcing experimental-observational Abilities

科学教育工作者已经意识到计算机在科学教学中的不可或缺性，不仅因为它具有存储信息和访问信息的能力，而且还因为它在使用不同软件方面的灵活性，这些软件有助于实现现代科学教学的目标，包括培养高级推理、解决问题的能力、批判性思维和协作能力。计算机使用的成功部分取决于高质量软件的开发，而不是硬件。使用计算机软件所产生的学习体验的有效性是由使用的软件类型、教学风格和学习风格等因素决定的。我们研究的教学范式基于斯金纳的程序化学习思想和强化理论，将教学内容分成小的部分，让学生一次掌握一个。软件的常见示例是教程、练习和实践。我们研究的计算机模拟……更多的是软件的典型例子，它们属于启示性范式，引导学生通过发现学习的过程。当学生与模型互动时，每节课背后的理论和概念都会被揭示给学生。这个软件只是作为学生和现实生活中的模型之间的中介。我们研究的另一种范式是猜想范式，在这种范式中，学生们可以根据个人经验操纵和检验想法和假设。计算机有利于实验的进行和对给定主题信息的探索。一切都在学生的控制之下。这允许学生检查，改变报价和内部结构，影响模型的行为。数据库程序是鼓励解决问题、学生探究和技能发展的教育工具。此外，数据库概念的引入鼓励学生发展其他技能，如组织数据，共享信息，方法，分析信息中的关系，搜索信息，检验假设，发现关系和相关性。少

Science educator have realized the indispensability of computer in science teaching not only because of the power to store information and to access but because of the flexibility in the use of different softwares that help realize the goals of modern science teaching which include fostering of high-level reasoning, problem-solving skills, critical thinking and collaboration. The success on the use of computers is partly dependent on the development of quality softwares more so than the hardware. The effectivity of the learning experience resulting from the use of computer softwares is determined by factors like the type of software used, the teaching and learning styles.The instruction paradigm which we investigate is based on Skinner's ideas of programd learning and reinforcement theory and subject matter is broken into small parts which the students should master one at a time. Common examples of softwares are the tutorials, drills and practice.Computer simulations which we investig … More ate are the typical examples of software that fall under the revelatory paradigm which guides the students through the process of learning by discovery. The theory and concepts behind each lesson are revealed to the students as they interact with the model. The software, then just acts as a mediator between the student and a model of some real life situation.The other paradigm which we investigate is the conjectural paradigm wherein the students are given experiences in which they can manipulate and test ideas and hypotheses based on personal experiences. The computer facilitates the performance of experiment and exploration of information on a given subject. Everything is under the control of the student. This allows the students to examine, change quotation and internal structures which effect the behavior of the model.Database programs are educational tools that encourage problem-solving, student inquiry, and skill development. In addition, the introduction of the concept of database to students encourages the development of other skills such as organization of data, sharing of information, ways, analyzing of relationships in information, searching for information, testing hypotheses, discovering relationships and correlations.
