RT journal article T1 Influence of the Algorithmization Process on the Mathematical Competence: A Case Study of Trainee Teachers Assessing ABN- and CBC-Instructed Schoolchildren by Gamification A1 Piñero Charlo, José Carlos A1 Noriega Bustelo, Rocío A1 Canto López, María del Carmen A1 Costado Dios, María Teresa A2 Didáctica A2 Psicología K1 assessment K1 trainee teachers K1 algorithmization K1 gamification K1 ABN K1 CBC K1 educational escape rooms AB In this manuscript, schoolchild mathematical competencies have been assessed by using educational gamification methodologies; specifically, Educational Escape Rooms (EER). To ease the interpretation of results, Spanish schoolchildren trained by using two different methodologies (ABN and CBC) were selected to participate in the experience. The gamified environment used as assessment tool was co-designed by trainee teachers, on-service teachers, and university researchers. The design was implemented in different educational centers and the results were transcribed to deliver a didactic analysis. Among the findings of this study, we uncovered: (i) the reduction of the math anxiety, (ii) the different performance of the schoolchild involved-ABN students show an additional and positive 10% development of certain mathematical competences-and (iii) a positive didactic-mathematic development of the participant trainee teachers.
