Data were collected from the study "Beliefs scale for the Use of Vee Diagrams of pre-service teachers" consisting of 20 Likert-type questions,and "Open-ended Questionnaire about the Use of Vee Diagram in science education laboratories," which includes 10 open-ended questions. First, the students were taught about Vee maps and diagrams for one week, and then some students volunteered for the scale, questionnaire and interview-application. Data were obtained for the quantitative and qualitative parts of the study. A mixed-methods design was used. Results indicate that pre-service teachers have positive beliefs towards the use of Vee diagrams in science education laboratories and there is a cross-relation between their beliefs and correct drawings for Vee diagrams.
