2。1 Academic achievement

2。1。1 The concept of academic achievement

Education is a process by which man transmits his experiences, new findings, and values accumulated over the years, in his struggle for survival and development, through generations。 Accordingly, one of the aims of education is to strengthen the inpidual's and societies’ problem solving capacity, ability and culture starting from basic education and at all levels in each field (Fdrge, 1994)。 Academic performance is generally a pedagogical terminology used while determining learners’ success in formal education and which is measured through reports, examinations, researches, and ratings with numerous factors or variables exerting influences (Kassu et。al, 2016)。

Academic achievement or academic performance can be defined as the outcomes that indicate the extent to which a person has accomplished specific goals that were the focus of activities in instructional environments, specifically in school, college, and university。 School systems mostly define cognitive goals that either apply across multiple subject areas (e。g。, critical thinking) or include the acquisition of knowledge and understanding in a specific intellectual domain (e。g。, numeracy, literacy, science, history)。 Therefore, academic achievement should be considered to be a multifaceted construct that comprises different domains of learning。 Because the field of academic achievement is very wide-ranging and covers a broad variety of educational outcomes, the definition of academic achievement depends on the indicators used to measure it。 Among the many criteria that indicate academic achievement, there are very general indicators such as procedural and declarative knowledge acquired in an educational system, more curricular-based criteria such as grades or performance on an educational achievement test, and cumulative indicators of academic achievement such as educational degrees and certificates。 All criteria have in common that they represent intellectual endeavors and thus, more or less, mirror the intellectual capacity of a person。 A thorough, short, and informative overview of academic achievement is provided in Spinath (2012)。 Spinath emphasizes the importance of academic achievement with regard to different perspectives (such as for inpiduals and societies, as well as psychological and educational research)。 No matter how we define academic achievement, it is commonly acknowledged that the urge to improving the academic achievement is one of the main goals of education and educational programs。论文网
