The aim of this report is to work with the evidence collected in WP2 and WP3 to elaborate hypotheses that will be tested in WP4 and WP5. WP4 and WP5 have slightly different goals, that could be framed as different research questions: 1. Track 1 of WP4, quasi-experiment: In group discussion of controversial issues; which factors contribute to an increase in girls' political self-efficacy in different compositions of pupils? 2. Track 2 of WP4, lab experiments: will test hypotheses on which are the constraints that girls find in class discussions that inhibit them from developing political efficacy, whereas boys develop higher levels of internal political efficacy. 3. WP5's aim is to design an intervention that will solve the issue, that is, that will allow girls to develop internal political efficacy in class discussions similarly to boys. 4. In addition, we found an important gap in the literature regarding the potential intersectionality and accumulation of inequalities for girls with different backgrounds/situations (class, origin, ethnicity...). For that reason, within WP2 we have further explored this question using analysis of secondary data (ICCS, ESS). Do gender gaps differ according to socioeconomic characteristics such as social class/ parental resources and origin/ethnicity among adolescents? And, among the adult population?
From our work in WP2 and WP3, what evidence/findings/results will help us develop answers and hypotheses to each of these questions. The answers and hypotheses for the WP4 and
WP5 will be presented in the chapter 5.
