Following the renewed general programs of Lithuanian secondary education i.e., by adjusting the content and teaching/learning goals of each subject, not only knowledge, but also their applications, real problems solving and reasoning have emphasized in the teaching process. Therefore, not only the conveyance of subject matter knowledge, but also teaching students to think and understand is particularly important. In order to assess the student's level of uptake of knowledge and its application, it is necessary to identify the process of thinking and understanding of subject matter, to capture errors and incorrect thinking. When the causes of errors are known, it is possible to define what knowledge or skills are missing. This article deals with the typical errors that have made when solving problems from the light phenomena. These are subject errors caused by a lack of knowledge or wrong under-standing of material, errors caused by gaps of application abilities and inattention errors. Mastering peculiarities of students' knowledge of light phenomena was studied by analysis of problems solutions. For this purpose, the 1747 problems solving of students' of young physi-cists school “Foton” of Siauliai University were analyzed. The quantitative and qualitative analysis of problems solutions showed that the prob-lems of light phenomena for students of young physicists school “Foton” were moderately difficult (0.65). It can be argued that students are well mastered this physics course and are able to apply their knowledge in specific situations. The study revealed a typical subject, skills and inattention errors that were done not only in the "Photon" problems solving, but also dur-ing the lesson or the control work, doing homework, participation in the Olympiad and so on. There are some tips on how to avoid those mistakes.

The authors from Faculty of Science University of Hradec Králové prepared worksheets for teaching topic “The rainbow formation” in subject physics at high school through laboratory work, which combines classical experiment and computer model. Classical experiment can be done with tools commonly available in the school science lab. A computer model based on geometric and physical analysis of the problem is to create a table and graph through spreadsheet software. Carefully prepared worksheet was provided to several teachers at different types of high schools in Hradec Kralove and the surrounding area. Addressed teachers used the methodology and worksheets for certain groups of students. Efficiency of the method was tested by pre-test and post-test and evaluated with method of normalized gain. Each of the teachers gave both tests to experimental and control group. The results confirm the hypothesis that high school students who have completed experimental teaching of the topic of “The rainbow formation” understand optical phenomena better than students who did not pass this teaching.

Learning Regions in Slovenia are in place for understanding sustainable development at local and regional level. In recent years, municipalities and various organizations have established over Slovenia at the different settings that need to connect to a joint bid. The school is growing experiential education and increase the usefulness of the knowledge in practice. New challenges in education are emphasized by the European Commission, which encourages Member States to responsibly carry out the educational process. The emphasis is on broad capabilities that open the door to different activities. More attention should be paid to the intergenerational cooperation, where in addition to the practice education and responsibility is also imparted.
