Abstract. Using 6 years of evaluation data, we assess the medium- and long-term
impacts upon a diverse range of students, teachers, and schools from
participating in a programme of protracted university-mentored projects
based on cutting-edge space science, astronomy, and particle physics research. After having completed their 6-month-long projects, the 14–18-year-old school students report having substantially increased in confidence relating to relevant scientific topics and methods as
well as having developed numerous skills, outcomes which are corroborated
by teachers. There is evidence that the projects helped increase students'
aspirations towards physics, whereas science aspirations (generally
high to begin with) were typically maintained or confirmed through
their involvement. Longitudinal evaluation 3 years later has revealed
that these projects have been lasting experiences for students which
they have benefited from and drawn upon in their subsequent university education. Data on students' destinations suggest that their involvement in research projects has made them more likely to undertake physics
and STEM degrees than would otherwise be expected. Cases of co-created
novel physics research resulting from Physics Research in School Environments (PRiSE) has also seemed to have a powerful effect, not only on the student co-authors, but also participating students from other schools. Teachers have also been positively
affected through participating, with the programme having influenced
their own knowledge, skills, and pedagogy, as well as having advantageous
effects felt across their wider schools. These impacts suggest that
similar “research in schools” initiatives may have a role to play
in aiding the increased uptake and diversity of physics and/or STEM
in higher education as well as meaningfully enhancing the STEM environment
within schools.
