From the Philippines, Morren provides a detailed description of creating reading materials in the Sama Bangingi language with a strong commitment  to linguistics. Of 435 pages in his dissertation, 90 are about the prepartory work of linguistic analysis and orthography development, while only 26 address the materials themselves. In addition, the section about the materials covers more about the content of the materials than the process itself. He does describe using an eclectic approach to teaching reading, rather than selecting a single school of thought, but his description of the Sama Bangingi materials bears a strong resemblance to Gudschinsky's linguistically based approach \cite{morren_descriptive_1977} 174-179. Unlike many of the other case studies, Morren includes complete copies of the materials at the end of his dissertation.
