The manufacturing of a Premount Base - Essay Example The manufacturing process was aligned and synchronised after the launch of Computer Numerical Control. The performance and machining characteristics of the Computer Numerical Control is consistent, and possibility of production or machining error is minimal. The human error has previously consumed significant effort and time, and in cases have been cause of production downtime. The evolution of the Computer Numerical Control is in compliance with the quality standards. The material for the fabrication of pre-mounting base shall be inspected through several non-destructive techniques to verify its compliance against standard, and strength. The metal identification of the job piece is important; the identification of the metal constituents through metal identification shall conform to the description provided by the vendor. This test shall be followed by hardness measurement; the hardness of the job piece shall be within the range as described in ASTM standards. The dye penetrant test of the job piece is recommended to verify the possibility of existence of external cracks on the job piece; it is strongly recommended that the cracked job piece shall be rejected. The ultra-sonic flaw detection shall be conducted; the test will verify the existence of internal flaws of the job piece. Beside ultra-sonic flaw detection, another recommended technique shall be eddy-current testing. The machining process for the pre-mounting base is simple. The job piece after certain inspection and quality checks should be placed on the lathe machine for trimming. It is important that the job piece shall be not greater than 2mm from the maximum required length. The quality of the cutting tools has to be ensured and maintained. The lathe machine shall be suitable for this job. The fabrication of the pre-mounting base requires essentially straight machining. After machining, the drilling of holes at specified

Teaching Of Primary Science Essay Example | Topics and Well Written Essays - 2000 words

Teaching Of Primary Science - Essay Example It also provides examples of schools that have experimented context-based teaching in science in classrooms, and a curricular example that teachers can modify to increase student understanding of any curricular area. Finally, it provides online resources and a podcast that provide teachers with additional ideas for making their lessons more interesting and engaging, empowering, and enlightening classrooms. There have been many studies that indicate context-based approach is essential in order for student learning to take place. Research reveals that teaching Strategies are necessary in schools for teachers to effectively increase student achievement. The focus of this research study is to examine effects of context-based approaches in teaching science in Classroom. The review of literature will look at several factors related to teaching strategies. Those factors include the Traditional view of teaching science, problematic questions that arise in this research, importance of context-based teaching, in classroom. ... Context-based approaches to teaching science in primary school have become widely used over the past two decades. They aspire to foster more positive attitudes to science while, at the same time, provide a sound basis of scientific understanding for further study. One of the most distinct trends of the last two decades in science curriculum development across a number of countries has been to use contexts and applications of science as a means of developing scientific understanding. Teaching in this way is often described as adopting a context-based approach. The trend toward the use of context-based approaches is apparent across the whole age spectrum from primary through to university level, but is most noticeable in materials developed for use in the secondary age range. Traditional Teaching Style of Science Over the last two decades reports have traced students' increasingly negative attitudes to Science in Australia over the primary years of schooling, and the associated decrease in student participation in post-compulsory science (Goodrum, Hackling, & Rennie, 2001; Tytler, 2007). This decline in interest in Science in the early years of primary education is of particular concern, since it is in these years that attitudes to the pursuit of science subjects and careers are formed (Speering & Rennie, 1996). A number of studies have explicitly linked this decline in student interest with the nature of the traditional science curriculum and its inability to make science meaningful and interesting to students (Fensham, 2004; Lyons, 2006). By making Science more relevant to a broader audience we can prepare prospective science degree students and professionals, as well as
