Education is one of the most important factors in determining future success. Everyone should have the same opportunity to receive an education and pursue his or her talents and interests!

On the whole, financially-disadvantaged children have less access to education. 'Impact' describes what we want to improve for this target group and society as a whole. For example, we encourage interest in subjects, like math, which are crucial for many career paths, but also cause issues for many students. The learning materials we provide allow for independent learning, thus helping students help themselves. Our target audience develops a positive attitude towards learning and cultivates his or her own educational aspirations and goals. In the long term, we help ensure that all students finish school successfully and find personal and professional fulfillment.

Our Impact Logic

The following graphic describes our impact goals and our approach to reaching them. We also broke down in detail the problems we are addressing, our target groups and the change in behavior we seek to affect with our activities in each of them.

The Problem

Educational inequality is a worldwide issue: virtually all public school systems around the globe are based on a teacher-centered learning approach. This means that a group of students learns the same topic at the same pace with the same teaching method. In consequence, worldwide parents spent 63.57 billion on private tuition in 2016 and the tutoring industry is expected to surpass $100 billion by 2018 (Global Industry Analysts, 2016). It is therefore not surprising that the educational prospects of a child depend heavily on the parents' income (PISA, 2015). Children from disadvantaged background are therefore more likely to underperform at school and, in turn, have worse job prospects and a higher risk of perpetuated poverty later in life.

Our Impact Goals

Target group 1

High School Students from low-income or non-academic households.

What we want to achieve
  1. Students use the available external learning aid they need in addition to school.
  2. Students are confident and believe that they can succeed at school.
  3. Students achieve good grades and a satisfying GPA.
  4. Students have a positive attitude towards education and set their own learning goals.
  5. Students find a satisfying job and are lastingly protected from financial poverty.

Target Group 2

All high school students.

What we want to achieve
  1. Students quickly and easily find high-quality and relevant learning content and practice opportunities.
  2. Students learn at their own pace and according to their needs.
  3. Students independently pursue topics according to their interests and individual potential.
  4. Students are empathic towards one another and support each other.
  5. Students learn together regardless of culture, nationality and background.
  6. Students find an activity that is meaningful to them during and after school and college and develop a positive social impact.

Target Group 3

Teachers, undergraduates who are obtaining a teacher's degree, and people who volunteer in an educational capacity.

What we want to achieve
  1. Educators use a range of opportunities to support and enrich lessons digitally.
  2. Educators use resources to personalize students' learning experiences and to give extra support in individual areas of weakness for any given student.
  3. Educators contribute actively and collaboratively to create new content.
  4. Educators understand and shape education as a participatory, co-creative process with students.

To learn more about how students work with - and how we can improve their experience - we have created the Serlo Lab School. In the Lab School, we can observe close-up as students use for their studies.
