Goal of our paper
Does the use ofprogramming with Scratchin math classes improve
students’ learningoutcomes?

Colombian students and maths
PISA 2012 results
376 points in maths (OECD countries average: 494)
Ranked 61st (out of 65 participating countries)
Students showed high levels of anxiety towards maths

Code to learn (I)
Logo programming language
Developed in the 1960s
Its educational impact wasintensively investigated inthe 70s and 80s
Students’ improvements inmaths (and otherdisciplines) were proved
“Disappeared” from theeducational landscape sincemid-90s

Code to learn (and II)
New visual programming languages
Alice, Kodu, Scratch
Very promising research literature
There is need for empirical studies

Mathematical processes investigated
Rubric
Modeling of processes and reality phenomena
Reasoning (making predictions and justifyingarguments)
Problem formulation and problem solving
Exercising (comparison and execution ofprocedures and algorithms)
Following guidelines set by the Ministry ofNational Education of Colombia

Conclusions
The development of CT using Scratch allows students ofprimary education to improve their performance in terms ofmathematical processes of modeling, reasoning, problemsolving and exercising.
(At least some parts of) the math curriculum in Colombianschools does not help in developing these skills.
Math learning at schools seems to be more focused on theinternals of mathematics, rather than on acquiring skills touse math-based knowledge.

Future Work
1 Does computer programming foster reading and writing skills?
2 Programming with Scratch as an educational tool in differentsubjects (social studies, language arts) and grades.
3 OK, but do the students really learn to code and developcomputational thinking?
