The purpose of this study was to evaluation of the 6th-grade elementary experimental science curriculum based on Bloom› s cognitive indices according to teachers perspectives in shahrekord. This research has a qualitative-quantitative approach in terms of methodology. The study population included all sixth grade teachers in Shahrekord in the first semester of the academic year 19-2019. Due to the low size of the population, all of them, 100 people (46 females and 54 males) were selected as the research sample by census sampling method. A researcher-made questionnaire was used to collect information, the retest validity of which was 0. 85 at two weeks interval. Descriptive (mean and standard deviation) and inferential (paired t) tests were used to analyze the data. Findings from the qualitative section showed that a total of 48 concepts were obtained for 14 chapters of the book of experimental sciences, which fall into 5 thematic categories (chemistry, biology, physics, geology and information technology). Also, the results of the study of the degree of attention to the concepts extracted from each chapter according to Bloom› s cognitive indicators from the perspective of teachers separately for each chapter showed that only in the third, fifth, sixth, tenth, twelfth and fourteenth chapters, All levels of Bloom› s cognition have been reasonably considered; In other seasons, the focus has been more on Bloom› s low cognitive levels. Also, according to teachers, in compiling the sixth grade experimental science textbook, more attention has been paid to the lower levels of Bloom› s cognitive hierarchy, and the more we move from the first level of the hierarchy to the higher levels of Bloom› s cognitive levels, the less attention is paid to high-level concepts.
