An Experimental Study to Determine the Relative Effectiveness at the Secondary Level of Two Methods of Instruction

ABSTRACTYoung children's initial categories often are not identical to the adult category labelled by the same word. Eventually, children's categories must evolve to correspond to the adult standard. The purpose of this study was to consider the relative effectiveness of four input strategies in inducing the child to learn the adult-appropriate label and begin to form a new category. Fifty-six children aged 2;0 were taught new labels for objects that they included in categories labelled by different names. Comprehension and production post-tests were then administered. As expected, the most effective strategy involved labelling an object and providing both a physical demonstration and a verbal description of important attributes that made the object a member of the adult-appropriate category. The label plus physical demonstration strategy was next most effective. Neither the label plus verbal description strategy nor the label only strategy was effective for children of this age. Results also indicated that these 24 month olds did not yet honour the convention of mutual exclusivity of basic level categories.

Purpose - The purpose of this experimental study is to investigate the impact of teaching Oriental Music using Blended Learning (BL) approach for the students of senior secondary level in Sri Lanka specifically focusing on their achievement on required competencies of Oriental Music at Ordinary Level. The study analyzes the academic performance of students with detailed comparison of BL environment and traditional learning environment. Authors propose the application of BL approach to teach Oriental Music and study its impact on improvement of students’ competency. The study conducted with the application of a mixed instructional design model of objectivist and constructivist approaches for the design of the blended learning course in a student centred learning environment. Methodology - The study was directed by using true experimental study design with pretest and posttest control groups. BL was applied to the experimental group and the traditional instruction method was applied to control group. 9 schools from Colombo district were randomly selected for the experimental and control groups covering all the three existing school types of Sri Lanka. The study group consisted of 360 students of Grade 10 and Grade 11 who has been studying Oriental Music as a subject for General Certificate of Education Ordinary Level. To analyze the data Descriptive statistics, Paired samples t test, Independent samples t test were utilized. Findings - The findings of the experiment indicated that students who has studied Oriental Music under BL strategy showed a significant improvement in their music academic performances after the intervention. The mean post-test of the experimental group was 71.75 which is significantly higher than the mean control group which was 52.07. The mean difference was 19.68 1.91. Hence, there is a statistically significant increase in the performance of students who studied Oriental Music under blended learning. Thus, it is clearly evident that the blended instruction was effective. Significance - This study indicated a positive platform to mould and cater the entire teaching learning process by introducing BL strategy to Sri Lankan secondary education system and fulfilled an existing research gap by utilizing BL to teach highly traditional abstract art. Results of the study contributes to the curriculum designing field with novel ideas to adapt blended instructions to teach secondary level students effectively.

Water is usually introduced into a die insert in die casting through a water line to reduce the temperature of the die insert and thus prevent its cracking. In many cases, a drilled waterline circuit is not possible due to confinement of the space. Bubblers or baffles then become typical water passage systems for die insert cooling. This paper presents an experimental study of the relative effectiveness of bubbler and baffle in die insert cooling. An internally channeled steel cylinder was designed as a die insert, with the blind channel drilled for water-cooling. Commercially available bubblers and baffles were inserted in the channel and water was introduced to cool the specimen when it was either heated in an air furnace or cyclically dipped into a molten aluminum bath. Thermocouples were mounted inside the wall of the cylinder to monitor the variation of the insert temperature under various cooling conditions. Experimental results indicate that both the bubbler and baffle can effectively lower the surface temperature of a die insert, with a bubbler being more suitable to cool a specific “hot spot” than a baffle. For a given cooling channel, within the experimental range, the bubbler with a smaller inner diameter has a better cooling effect to a “hot spot” than a bubbler with a larger inner diameter. Increasing the water flow rate always enhances the heat transfer between the cooling water and the sidewall of the cooling channel.

This experimental research is evaluated the significance of Yoga on Memory of Secondary School Students, aged between 13 and 17 years. Pretest-posttest of control and experimental groups are designed for this study. The total seventy students were included equally in both control and experimental groups. Before the experiment the researcher administered a pretest for measuring memory of the total seventy students which was measured through in terms of number of trials using Instructional Manual for Memory Drum ( Dr. Vivek Bhargava, Chairman, Harprasad Institute of Behavioural Studies, 41-12, Hardeep Enclave, Sikandra. AGRA(U.P.). And the same test was administered as post –test for both groups. The significance was measured through in terms of number of trials. To remove the difference statistically in the initial status of the two groups, the researcher analyzed the data with the statistical technique of Analysis of Covariance (ANCOVA). Thus both groups initial status had been equated. The main findings of the experimental study proved that the regular yoga practicing students develop the homeostasis of persons in a balanced manner. It helps to attain the complete self-realization. This study reveals that Yoga will assist to improve the students’ memory in a magnificent level. So, Yoga should be practiced for students in the schools of Kerala. Through yoga the students’ memory has increased.
