Research Methods Abstract Every research study begins with a problem that researches want to solve. For every problem to be researchable it must be the one that can be studied by collecting data and analyzing it. The steps without which the data collected will not move on into research process are: stating the problem‚ designing the research question and developing a hypothesis and/or purpose statements that will be supported at the end of the study. The first thing a researcher needs to

ASSESSMENT METHODS What is assessment? Black and William (1998) declare that the term assessment is generally used to refer to all activities teachers use to help students learn and to gauge student progress. There are many different forms of assessment‚ however they can generally be divided into two main categories; formative and summative which can be formal or informal. Formative assessment focuses on the gap between where a learner is in their learning‚ and where they need to be. Marshall

Welding is a method for the permanent assembly of metal parts. Arc welding can be divided at least three classes: arc welding‚ gas welding‚ and resistance welding. 1) Arc welding: Heat is generated by an electric arc and the parts are simply fused together and became one. In some cases electrode is used that provides a filler material. 2) Gas welding: The burning gas (oxygen and acetylene) raises the temperature of the part to be joined and a welding rod provides filler material. 3) Resistance

Throughout in this text V will be a vector space of finite dimension n over a field K and T : V → V will be a linear transformation. 1 Eigenvalues and Eigenvectors A scalar λ ∈ K is an eigenvalue of T if there is a nonzero v ∈ V such that T v = λv. In this case v is called an eigenvector of T corresponding to λ. Thus λ ∈ K is an eigenvalue of T if and only if ker(T − λI) = {0}‚ and any nonzero element of this subspace is an eigenvector of T corresponding to λ. Here I denotes the identity mapping
