Effectiveness research

Sumdog has been developed with the help of teachers and educational experts around the world.

To develop Sumdog's pedagogy, we work continually with educationalists across the country.

Effectiveness studies and case studies, together with regular focus groups and questionnaires, guide our pedagogy. In addition, consultation from independent experts and data analysis help refine our educational algorithms and user experience.

Glasgow study: 1½ years' progress in 6 months

We compared students using Sumdog frequently with those using it less. Those averaging over 1 hour weekly made 1½ years' curriculum progress.

This Sumdog study investigated how the length of time using Sumdog impacts math achievement.

The study was overseen by an academic from Glasgow University. To measure the acceleration in learning, the study relied on the natural variations in the length of time Sumdog was used from one class to the next. For pre- and post- testing, the study used Sumdog's own diagnostic test. To investigate this with more accuracy, we plan to conduct a new study with independent testing.

Pupils and teachers observed an improvement in both mathematics ability and attitude towards learning mathematics.

‘They are more motivated since they started Sumdog and grades have improved.’ C. Ramirez, Bonnie L. Garcia Elementary, United ISD Effectiveness Study

Validated by Dr. Afi Y. Wiggins from Texas State University, this study uses a quasi-experimental pre-test post-test design to explore the correlation between time spent on Sumdog and mathematics proficiency.

Students completed Sumdog's diagnostic test twice, to determine their mathematics proficiency level at the start and end of the study. The total length of time they spent on Sumdog between these 2 tests was recorded.

Using ANCOVA and effect size, this study found that the more time students spend on Sumdog, the greater their proficiency improvement in mathematics.

Students and teachers observed an improvement in both mathematics ability and attitude towards learning mathematics.

St Mary's Effectiveness Research Paper

This research paper by S O'Donnell (Partnership between the PCP and St Mary's University, Twickenham) looks at the effectiveness of Sumdog's game-based learning to improve children’s mental mathematics. The paper first considers the context of the school and why this research was chosen, while addressing the ethical considerations, then moving onto the bigger picture, reviewing the literature regarding mental calculation and game based learning.

Research found that 75% of the children said playing Sumdog had given them more confidence in maths, and 80% enjoyed playing the games, motivating them to practise their skills.
