Gupar Danjuma Hosea

Founder and CEO Center for Literacy Development in Africa (CLDA)

I graduated in 2008 from the College of Education, Gindiri and started teaching in 2009 as a classroom teacher. I managed a nursery/primary school as a head teacher and in addition taught Primary 1 for five (5) years from 2010-2014.

In the few years of my teaching experience, I discovered that many Nigerian children were struggling with literacy. As a result many pupils/students cannot read or write with efficiency. This became a burden on me. In 2011, I met a Canadian in Jos, Marlene Wiebe, and later on an American, Adrienne Lillo, who were missionaries in Nigeria. Together, we developed a phonics curriculum (The Phonics READING Adventure [TPRA]) which was published in 2014 by ACTS Bookshop. I have been promoting the materials and training teachers within the schools that are using the curriculum. This is happening in several states in Nigeria.

In order to improve and develop my training skills, I completed an MA in Early Childhood through the University of Roehampton, London (UK) with a speciality in early grades literacy. The title of my thesis was, ‘Why Nigerian Children Struggle with Literacy; the Challenges of Teachers’ Pedagogies and Inadequate Instructional Materials.’

On the 1st day of August 2019, The Phonics READING Adventure Africa Ltd was incorporated under the Companies and Allied Matters Act 1990. However, in other to achieve the goal and vision of literacy empowerment, the program is now registered as an NGO as the Center for Literacy Development in Africa (CLDA) on 14-02-2020 with RC No: 144206. Center for Literacy Development in Africa is currently the publisher of The Phonics READING Adventure materials.


Marlene .E Wiebe

Co-Founder Center for Literacy Development in Africa (CLDA)

Marlene served as lead teacher in the Toddlers Department (2-3 year olds) of Jarvis Street Baptist Church, Toronto, Canada. She also served as the Correspondence Course Secretary for The Toronto Baptist Seminary & Bible College (TBS) (1993-2003). She has served Nigeria since 2004. She conducted Bible, Reading and Library clubs from her home on the Faculty compound of Federal College of Education (FCE), Pankshin, Plateau State, Nigeria (2004-2010).

Seeing the need to greatly improve the reading skills of the faculty children she was teaching, she teamed up with Gupar Danjuma Hosea to do research and writing of The Phonics READING Adventure (TPRA) curriculum. The first five levels were published in 2014 by ACTS, Bukuru, Plateau State. Since that time she has published Levels Six and Seven (2016) and also produced a second edition of Levels One to Five (2017).

She has also teamed up with Adrienne Lillo with Global Scholars, USA, also serving in Nigeria to produce forty eight Companion Readers to enhance the learning at all seven levels of TPRA.

Marlene serves as an Associate with Global Scholars Canada as she continues her interaction with Gupar Danjuma Hosea on the TPRA project.

Rudolph H. Wiebe

Rudy began his working career by teaching High School Science (1968-1970). While pursuing Theological Studies, he served as a pastor (1971-1975). He lectured at The Toronto Baptist Seminary & Bible College (TBS) where he also served as Registrar (1975-2004). During four of those years he was acting editor of The Gospel Witness. He then served as a principal lecturer in the Christian Religious Studies department of the Federal College of Education (FCE) Pankshin, Plateau State (2004-2016). During his tenure there, he served as senior editor on the three volume text book project for the CRS department that was published by ACTS, Bukuru, Plateau State.

With FCE giving leave on a modular basis, he teamed up with Dr.Rob Lillo to equip eight Nigerian Bible Translators with NT Greek (2008-2013) and a new group of students (2014). The outcome of this modular approach was the publication of a revised edition of the textbook by Mary Catherine Preus Let’s Study New Testament Greek (Revised by R. A. Lillo and R. H. Wiebe) Bukuru: ACTS 2011.

He has worked with Marlene on the TPRA curriculum with proofreading and editorial assistance.

He is currently field testing the Preus Greek Grammar with two sets of Canadian NT Greek students in order to produce a revised edition to be published by ACTS in 2018, God willing. He continues to serve Nigeria from Canada as an Associate with Global Scholars Canada.
