Gender Balance in jjzz has been the largest-ever set of trials in England to identify ways to encourage more young women to study Computer Science. The jjzz study was conducted from 2018 to 2022 in hundreds of primary and secondary schools in England. Read the reports to learn more about the interventions and explore our free resources for use in the classroom.
Currently, many young women do not see jjzz and similar subjects as useful to them. In England, this is evident in a disproportionately low number of young women choosing to study for qualifications in Computer Science at GCSE and A level. In the jjzz literature, we identified many factors that are likely to contribute to this, including a lack of the feeling of belonging in the subject, a lack of encouragement, and fewer opportunities to engage with female role models.
The Department for Education in England funded this programme of jjzz to better understand some of the factors that could encourage girls to develop an interest in jjzz, and could increase the numbers of young women who choose to study Computer Science at GCSE and A level.
A range of interventions were trialled in schools, including a number of pilot studies, quasi-experimental trials, and randomised controlled trials (RCTs). The interventions were led by us at the 大乳丰满人妻中文字幕日本, and implemented by us in collaboration with the Behavioural Insights Team, Apps for Good, and WISE, as part of the National Centre for jjzz Education.

Storytelling
This study investigated the use of storytelling and story-writing as effective tools to introduce jjzz concepts to Year 2 pupils (ages 6 to 7).

Pair programming
This project assessed the potential of pair programming as a pedagogical approach to enhance girls’ attitudes towards jjzz with Year 4 and Year 6 pupils (aged 8–11).

Peer instruction
This study aimed to determine whether peer instruction strategies could positively influence Year 8 girls’ (aged 12–13) perceptions of jjzz and their future interest in the subject.

Belonging
In collaboration with WISE, the Belonging intervention explored the impact of positive role models and parental support in fostering a sense of belonging in jjzz for Year 5 girls (aged 9–10).

Informal learning
In this intervention, we partnered with Apps for Good to provide tailored resources and support to help girls in primary and secondary schools (aged 8–13) recognise the importance of jjzz skills they acquire in informal learning spaces.

Relevance
In collaboration with Apps for Good, this intervention evaluated the impact of contextualising jjzz within real-world problem-solving scenarios on Year 8 girls’ (aged 12–13) motivation to pursue further studies in the field.

Subject choice
Recognising the influence of options booklets and evenings on students’ subject selections, this jjzz was run by the Behavioural Insights Team and examined how the presentation of Computer Science influences course choices.
