Clements, D.H., & Meredith, J.S. (1993). Research on Logo: Effects and efficacy. Journal of Computing in Childhood Education, 4(4), 263–290
Summary of findings
The most comprehensive review of Logo research at the time. Logo can meaningfully improve geometric thinking, problem-solving processes (planning, debugging, monitoring and reflection), mathematics understanding, creativity, collaboration, and self-esteem—especially when teachers provide guidance and the classroom uses a constructionist approach. Benefits are not automatic from software alone; mediated, well-implemented use produces the strongest results. Many individual studies showed positive effects, with some mixed findings on transfer to non-Logo tasks.
Clements, D.H. (1987). Longitudinal study of the effects of Logo programming on cognitive abilities and achievement. Journal of Educational Computing Research
Summary of findings
One of the key longitudinal studies. Students using Logo showed positive gains in cognitive abilities and academic achievement over time compared to controls, supporting Logo’s potential to influence broader thinking skills when used consistently.
Pardamean, B., et al. (2011). The Effect of Logo Programming Language for Creativity and Problem Solving. Proceedings of the 10th WSEAS International Conference on E-Activities (EACT-23)
Summary of findings
An experimental study with 85 fifth-grade students. After eight weeks, the Logo (turtle graphics) group scored significantly higher than the control group on problem-solving skills (logical word problems and figural) and on several measures of figural creativity—especially flexibility and originality. The authors concluded that Logo programming can improve both creativity and problem-solving in elementary students.
Lewis, C.M. (2010). How programming environment shapes perception, learning and goals: logo vs. scratch. SIGCSE '10: Proceedings of the 41st ACM Technical Symposium on Computer Science Education, 346–350
Summary of findings
A classroom study comparing sixth-grade students learning Logo versus Scratch. Students who used Scratch were stronger at interpreting conditional statements; differences on loops were not significant. Contrary to expectations, Logo learners reported higher confidence in their ability to program on average. Neither group differed in plans to continue programming after the course or in how difficult they found the material—suggesting that environment shapes specific comprehension and confidence outcomes, not a simple “better tool” narrative for every goal.
