The intervention proposal in the classroom consisted of determining the perimeter and area of flat figures without length measurements. The intervention allowed to consolidate the basic concepts of flat geometry and the development of metric thinking through the use of Geoplano as a concrete material. The pedagogical process was carried out with the organization and execution of a didactic sequence that started with the recognition of previous knowledge, from the diagnostic test and the continuous monitoring in the learning levels of the students, until the verification of results through the application of the post test. These results show the learning and characterization of the figures as well as the recognition of perimeter and area concepts in different plane figures.

Esta investigación acción cualitativa explora la contribución de dos talleres de vocabulario, al aprendizaje de colocaciones, estructurados bajo el enfoque léxico, en estudiantes de sexto grado de una Institución Educativa Departamental (IED). El estudio se realizó con 18 estudiantes de edades entre los 10 y los 13 años, y la información se recolectó a través de artefactos de los estudiantes, notas de campo de la maestra, y dos cuestionarios. Los hallazgos demostraron un efecto positivo de los materiales que se desarrollaron bajo los principios de adquisición de segundas lenguas y el marco de referencia para el desarrollo de materiales y el enfoque léxico. Además, el enfoque léxico y las estrategias de aprendizaje respaldaron la enseñanza de las colocaciones a través de diversas actividades que iban desde el simple reconocimiento de las colocaciones y finalizó con la redacción de un texto corto.

This study showed how worksheets based on vocabulary learning strategies contributed to the development of fourth grade students’ writing. This study was conducted in a public, rural school with fifteen students in Cajicá, Colombia. The data gathering instruments were field notes, students’ artifacts and tests. The study followed the qualitative approach and was developed under the action research methodology. The findings indicated that the design of worksheets based on vocabulary strategies made students feel motivated not only to learn new words, but also to understand the strategies that allowed them to start the process of writing. Moreover, the writing strategies were a successful approach for students because they learned how to write simple sentences. Also, using the models provided they could write simple paragraphs. Finally, all of these activities allowed students to improve their performance. This study helped learners feel motivated to learn faster and encouraged them to understand the importance of the use of vocabulary, to learn new strategies and to value meaningful writing feedback.
