Abstract: This paper reports on the use of open education resources (OERs) for teacher professional development in Gabon. Through Stoner’s life phases of learning technology integration the researcher ascertained: (i) how does the existing TPD curriculum in Gabonese educational system fit with the course objectives in Gabon as stipulated in policy; (ii) what are the appropriate OERs in ODL which can be used as LT for TPD in Gabon; and (iii) how can OERs be used in the design integration of ODL for the TPD of Gabonese teachers. A purposeful sample was used to understand the existing TPD curriculum in Gabon and how OERs could contribute towards teaching English as a foreign language. A qualitative bounded case study with design research was the appropriate research design and methodology for this research. The design principles were re-organized as five themes: ODL, TPD, ICT, Education system, and OERs which were then structured as guidelines for the use of OERs in ODL for TPD in Gabon. The guidelines could benefit and support the Gabonese Education System, policymakers and academic institutions, lecturers, pre-service and in-service teachers in their quest to implement, integrate and use OERs in ODL for the TPD in Gabon.
