Texts are indispensable tools used in a language teaching environment. They help students learn both implicitly and explicitly. This learning activity guides the future of the student. The individualization processes of memories that are combined together with qualified texts would be shorter and more qualified. There are many affective approaches and cognitive approaches in curriculum because raising individuals with adopted basic human values is a universal phenomenon that takes place in all the education programs. In today's teaching processes, along with data mining, opinion mining is also included in educational processes. Equipping the input in students' memories with positive poles (the literature used polar), in terms of value load, will directly lead to the observation of the positive affective behaviours in students. The learning outcomes under the title of education values in native language programs are basically a product of value load mining. This paper focuses on classifying the value loads of the words in the reading texts in the primary education of 7th and 8th grade Turkish textbooks as positive/neutral/negative. The study also attempts to determine the positive/neutral/negative value loads that the textbooks try to convey to the students. This study is a qualitative study and is structured with a document review method. Rapid Miner and MS Excel programs were used to acquire data, which was described in the context of value load that is transferred. With the results obtained, it can be concluded that, at the word level, the textbooks try to convey positive and negative values that are approximately the same ratio without using a certain systematic approach that would consider adjusting the text content for the grade levels.
