This article aims to show the results of implementing a training methodology in a group of participants within an intensive course on educational innovation. The motivation for this course was to promote innovative ideas that could be scaled into possible open educational entrepreneurship projects. Based on descriptive statistical analysis, that included a multivariate statistical analysis, an analysis of means and nonparametric tests of the data comparison of medians and ranges and Spearman's correlation, this article considered the SEL4C methodology, which was intended to support the ideation process and develop the participants' perceived achievement of social entrepreneurship and complex thinking competencies. The proposed methodology was validated to develop social innovation ideas even in a limited time and improved the participants' perception of achieving both competencies. This article contributes to the validation studies of this methodology and the academic approaches that seek efficient tools for acquiring and developing transdisciplinary competencies.
