IMIS

The program consists of short, one-off interventions that follow an inquiry-based approach and include hands-on activities and science communication in the pupils’ heritage language We report the students’ evaluation of the program and assess effects on students' motivation for science as well as for their heritage language (Portuguese). We applied a randomised block design with waitlist control groups and repeated measures. Eighty-three multilingual students aged 6 to 17 years participated in the workshops, which were held in six cities in two European countries (Germany and the United Kingdom). We also report in the pre- and posttest results of students’ self-report of their intrinsic interest, attainment value, self-concept of ability, as well as intention for future participation in science , and their intrinsic interest, attainment value, and self-concept of ability for Portuguese. We assessed further the effectiveness of the programme by means of a randomised waitlist control group design with repeated measures. The study was approved by the appropriate ethics review panel at Lancaster University and conducted in accordance with the provisions of the Declaration of Helsinki.
