This paper deals with a novel method for improving the traditional
“verification” laboratory in science education. Drawing on the idea of integrated instructional units,
we describe an instructional sequence which we call the Babushka concept. This concept
consists of three integrated instructional units: a
start-up lecture, a laboratory session and a wrap-up lecture. Like the Russian
nested doll, the sequence has a nested conceptual structure, moving from
“bigger” questions to “smaller” ones. The students are actively involved during
the lectures by answering reflective questions. This careful sequencing of
ideas and activities aims to help the students to relate new ideas to prior
knowledge, and to understand the purpose of the laboratory activity. The Babushka concept was implemented in a
master’s course in pharmaceutical technology and its impact was evaluated using
both qualitative and quantitative methods. The evaluation focused on the
students’ perceptions of the intervention as well as their learning gains. A
majority of the students found the Babushka concept helpful for their learning
and agreed that this concept should be used in other courses. Moreover, the number
of correct answers on the final written exam increased by 10%. We briefly
discuss one way to enhance the Babushka concept.
