The research has focused on high school students in theirfinalyear oflearning chemistry. It aimed atanalysinghow they feel confident in solving problems during chemistry lessons.
The study was performed among 102 students from an eight-year grammar school. The questionnaire comprised 21 statements and 33 open questions.
By using an 11-point Likert scaleand answers to open questions,therespondents indicated their feeling about progress or regress in their skills and competencies during the last three years.
