To fulfil the research, the following methods such as the analysis of literature, the quantitative analysis of the textbooks content, the statistical analysis of empirical data have been applied.

When examining integrated and non-integrated textbooks of different countries, it has been established that the average of ecological tasks varies from 7\% in the non-integrated textbooks and up to 12\% in the integrated ones. Comparing integrated and non-integrated textbooks of the same form the deviation of comparative rates of ecological tasks varies from statistically irrelevant to statistically absolute. The cases of statistically relevant deviation are fractionally prevailing. The examined non-integrated physics textbooks and integrated natural science textbooks, including the Lithuanian ones, do not basically differentiate evaluating the element of ecological tasks that comprise students{\textquoteright} preconditions of ecological education.},
