Abstract (Englisch):Background: Laboratory assistants in biology and medicine play a central role in the operation of laboratories in hospitals, research institutes, and industries. Their daily work routine is characterized by dealing with molecular structures/chemical substances (i.e. biochemistry) as well as cell cultures (i.e. cell biology). In both these fields of biochemistry and cell biology, laboratory assistants rely on knowledge about three laboratory tasks: responsible action, data management, and laboratory techniques. Focusing on these laboratory tasks, we developed a test instrument measuring the professional knowledge of prospective laboratory assistants (acronym: PROKLAS) about biochemistry and cell biology. Results: Confirmatory factor analysis (CFA) indicates that the test developed allows us to measure the professional knowledge of laboratory assistants in biochemistry and cell biology as two empirically separable constructs among laboratory assistants. CFA with covariates widely confirms the validity of PROKLAS in its respective subscales. Firstly, VET-related covariates predicted biochemistry and cell biology scores of students considerably better compared to the covariates related to general secondary school. Secondly, general biological knowledge predicted biochemistry and cell biology scores of PROKLAS. Finally, VET students’ self-efficacy in laboratory tasks and their opportunities to learn laboratory tasks are positively correlated to achievement in PROKLAS. However, we found a similar relationship for self-efficacy in English too. (IPN/Orig.)
