Learning environment is a physical or virtual context in which learning occurs. The learning environment is an important determinant of behavior. The aim of this study was to express the significance and necessity of learning environment. Additionally, the identification of instruments that measure the learning environment and also the ways for promotion the learning environment was the utmost importance. By present research, some databases including SID, Iranmedex, Irandoc, and Magiran were reviewed; on the other hand, Pubmed and Eric databases were searched using key words such as learning environment, educational environment, and educational climate. The results of this study were also categorized in three sections including; the importance and necessity of the learning environment (the impact on students’ behavior, academic achievement, and the success in learning, a comprehensive view about the process of education, and so on); learning instruments that measure the learning environment (MSLES, LEQ, MSEQ, DREEM, MSEI, Mini-STEEM, and so on); and the ways for promotion the learning environment (the role of managers, faculty, and the physical environment in enhancing the learning environment. One reason for an emphasis on the learning environment was its impact on academic achievement. It should be noted that important instruments have been designed for measuring the learning environment but these instruments are not applicable for measuring all elements of educational environment. As a result, every faculty should be familiar with this instrument in order to assess the class environment for promoting this environment.
