Math skills vary greatly among students enrolled in introductory chemistry courses. Students with weak math skills (algebra and below) tend to perform poorly in introductory chemistry courses, which is correlated with increased attrition rates. Previous research has shown that retention of main ideas in a peer learning environment is greater when partners have dissimilar abilities. Therefore, in an effort to improve student learning outcomes, we implemented peer learning interventions in our introductory chemistry laboratories to determine if math skills were enhanced when partners differed in math ability. Student performance and attitudes were analyzed in laboratory sections consisting of instructor-assigned partners who differed in math ability, compared to sections where students self-selected a partner. Students who were assigned math partners of different ability showed an 8% improvement in chemistry math concepts compared to no improvement among those who self-selected a partner, as assessed using pre- and post-math tests. Mathematical learning gains were particularly large (16%) for those students in the 50th percentile of math performance. Students also reported a significantly more positive attitude change about working with others compared to students who self-selected a partner. In addition, assigned students demonstrated a more positive shift in self-concepts such as chemistry knowledge and laboratory skills. This study illustrates that peer learning can serve as a useful and easy-to-implement tool to strengthen math skills and improve student attitudes in introductory chemistry laboratories.

Summative assessments are an exercise of authority and something that pupils cannot easily appeal. The importance of teachers being able to assess their pupils correctly is consequently both a question of national equivalence and individual fairness. Therefore, summative assessment is a paramount theme in teacher education, and we aimed to investigate the perceptions and competence of student teachers regarding common summative assessment practices. The study was conducted at three universities, two in Sweden and one in Finland involving prospective language teachers responding to an online survey (N = 131). In addition, interviews were carried out with 20 Swedish and 6 Finnish student teachers. The analysis of the data indicates that student teachers value practices that enhance communication and collaboration as well as the curricular alignment of summative assessments. With respect to perceived competence, the respondents in general felt most confident with deploying traditional forms of summative assessment, while they were more uncertain about process evaluation and oral skills. Regarding significant differences in the participants’ perceptions of competence among the three universities, Finnish university students reported higher levels in all variables. However, room for improvement was found at all universities involved.
