Abstract

using new technology in learning to improve the ability of instructors in avoiding run-ons sentences. To fulfill the aims of the study; the researcher adopted a null hypothesis which indicates that there is no significant difference between instructors' performance in pretest and posttest to avoid run-ons sentences by using the internet as new technology in learning. To achieve the aims of the study t-test for two dependent samples and percentage are used through out the data analysis. The analysis of results shows that the performance of instructors in posttest are better than in pretest by using the internet exercises to improve their ability in writing skill( avoiding run-ons sentences). In the light of findings, the using of new technology as an assistant tool in learning is recommended to facilitate the process of teaching and learning.

Abstract

The research work covers a study of the feasibility of producinglightweight ceramic thermal insulation bodies used for lining the furnacesby adding saw dust and AlF3 to the Dewechla clay (Kaolinite).AlF3 is achemical waste materials in the Akashat–factories in Rutba to theDewechla clay (kaolinite). Finely distributed Saw dust and ALF3 wereadded to clay with different weight percentages (0, 15, 25, 35 & 40) Wt%.Cylindrical shape samples (30mm diameter and 30 mm height) wereprepared by using the semi–dry method, moulding pressure was(500Kg/cm²). After drying at (110C◦), the samples were burnt at (900, 950,1000, 1050&1100) C◦. The fired samples were investigated to obtain theirproperties, bulk density, porosity ,compressive strength and thermalconductivity. It was possible to produce ligh-weight ceramic thermalinsulators with bulk density between (700 and 1300) Kg/m³ compressivestrength not less than (25) Kg/cm² and thermal conductivity between (0.2and 0.4) Kcal/m.h.c.
