Goal of our paper
Does the use of
programming with Scratch
in math classes improve
students’ learning
outcomes?

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 was
intensively investigated in
the 70s and 80s
Students’ improvements in
maths (and other
disciplines) were proved
“Disappeared” from the
educational landscape since
mid-90s

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

Modeling of processes and reality phenomena
Reasoning (making predictions and justifying
arguments)
Problem formulation and problem solving
Exercising (comparison and execution of
procedures and algorithms)
Following guidelines set by the Ministry of
National Education of Colombia

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

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