Effectiveness of Multimedia Mediated Teaching on Science Achievement of Class VII Students

Abstract

Throughout the World, We are going through a period of reflection on the teaching/learning process of the Science education, in order to maintain a healthy school environment. It is today's demand to teach science with a solid understanding of the most important scientific ideas by using new methods. Certain features of teaching science at the present time are fairly general. The biological Sciences usually treated as descriptive rather than experimentally and they are aligned to geography and geology rather than to physics and chemistry. The contribution of Science to the educative process is of two fold. On the one hand, it is informative, involving the acquisition, within the limits of the pupils' abilities, of the knowledge necessary for full participation in, and enjoyment of, life in the modem world. In the pre-technology education context, the teacher is the sender or the source, the educational material is the information or message, and the student is the receiver of the information. In terms of the delivery medium, the educator can deliver the message via the "Chalk-and-talk" method and overhead projector (ORP) transparencies. Basically, in lecture method, the teacher delivered the content to the entire class and the student listens to the lecture. Thus, the learning mode tends to be passive and the learners play little part in their learning process. It has been found that lecture method used for teaching sciences in schools has less effective. It is a method of one way process of imparting scientific knowledge. While on the other aspect of teaching, through various innovative methods students interact more and the teaching learning process become more effective than traditional teaching style. Hence I have decided to see the significance difference between traditional and innovative methods of teaching science in VII classes. The information provided in this research will help one to better understand why this study was conducted. Because technology is prominent in education, there was focus between two different methods of delivering simple step directions:. audio video j_ 1 , instructions (Multimedia) versus traditional lecture. Educators' today use both modes of instruction, but one will better result in the method of retaining information. The study is to determine the effectiveness of audio video instruction as opposed to the traditional lecture. Within a group of 70 students, students are going to be separated into two groups and each group of 35 students each group will going to be taught in totally different manner, one will attend normal chalk-n-talk other group will be taught through multimedia based methodology. It will be expected that the students who receive video instruction recalled more information than those who receives the traditional lecture instruction of the teacher in chalk-n-talk method. Because of the expected results, this study will suggest that the effectiveness of video instruction will be used as a method to support student learning. In the current scenario of educational institutions, multimedia has dig up its own kind of space in some or the other way as a tool of educational technology. Multimedia has overcome the barriers of time and space and provides evidence to be accepted as an anytime and anywhere tool for educating multi-disciplinary masses. The process of knowledge acquisition becomes more efficient when the learners experience an event through a multimedia simulation. Multimedia technology empowers the educational process by means of increased interaction between teachers and the students. Apart from the fact that multimedia can provide educators and students with endless possibilities of quality teaching and learning, taking vital considerations of the pedagogical strengths and limitations of Multimedia, it can be used to its fullest potency, and reach the eminence of 'New Educational Technology tool'
