Education-centered critical policy analysis of AI: Ghana's AI strategy as a case

National AI strategies increasingly guide governance, workforce development, innovation, and competitiveness, but less is known about how they frame education as a sector with pedagogical, cultural, ethical, and implementation demands. This study develops and applies an Education-Centered AI Policy Framework to analyze Ghana's National Artificial Intelligence Strategy, 2025-2035. Using critical qualitative policy document analysis, we examined the strategy through six components: policy purpose, teacher agency and professional learning, curriculum and assessment, language and culture, responsible AI and learner protection, and participation and implementation governance. Findings show that Ghana's strategy is ambitious and timely, especially in its emphasis on AI literacy, youth skills, TVET, workforce readiness, rural outreach, local language data, inclusion, and responsible AI governance. However, the education agenda is stronger on national AI readiness than on school-level implementation. Teacher agency, pre-service teacher education, curriculum progression, assessment guidance, AI disclosure, multilingual pedagogy, culturally responsive AI use, child-centered safeguards, and participatory governance remain underdeveloped. We also identify document-level concerns about transparency and coherence, including apparent AI-styled visual content without visible disclosure and a mismatch between a vision and mission figure and its textual explanation. We argue that Ghana needs a sector-specific, education-centered AI policy and implementation pathway that connects workforce readiness with teacher preparation, curriculum reform, assessment redesign, learner protection, infrastructure, local language instruction, culturally responsive pedagogy, locally responsive AI tools, and participatory governance.

Prompt Engineering for Responsible Generative AI Use in African Education: A Report from a Three-Day Training Series

Generative artificial intelligence (GenAI) tools are increasingly adopted in education, yet many educators lack structured guidance on responsible and context sensitive prompt engineering, particularly in African and other resource constrained settings. This case report documents a three day online professional development programme organised by Generative AI for Education and Research in Africa (GenAI-ERA), designed to strengthen educators and researchers capacity to apply prompt engineering ethically for academic writing, teaching, and research. The programme engaged 468 participants across multiple African countries, including university educators, postgraduate students, and researchers. The training followed a scaffolded progression from foundational prompt design to applied and ethical strategies, including persona guided interactions. Data sources comprised registration surveys, webinar interaction records, facilitator observations, and session transcripts, analysed using descriptive statistics and computationally supported qualitative techniques. Findings indicate that participants increasingly conceptualised prompt engineering as a form of AI literacy requiring ethical awareness, contextual sensitivity, and pedagogical judgement rather than technical skill alone. The case highlights persistent challenges related to access, locally relevant training materials, and institutional support. The report recommends sustained professional development and the integration of prompt literacy into curricula to support responsible GenAI use in African education systems.

GenAITEd Ghana: A First-of-Its-Kind Context-Aware and Curriculum-Aligned Conversational AI Agent for Teacher Education

Global frameworks increasingly advocate for Responsible Artificial Intelligence (AI) in education, yet they provide limited guidance on how ethical, culturally responsive, and curriculum-aligned AI can be operationalized within functioning teacher education systems, particularly in the Global South. This study addresses this gap through the design and evaluation of GenAITEd Ghana, a context-aware, region-specific conversational AI prototype developed to support teacher education in Ghana. Guided by a Design Science Research approach, the system was developed as a school-mimetic digital infrastructure aligned with the organizational logic of Ghanaian Colleges of Education and the National Council for Curriculum and Assessment (NaCCA) framework. GenAITEd Ghana operates as a multi-agent, retrieval-augmented conversational AI that coordinates multiple models for curriculum-grounded dialogue, automatic speech recognition, voice synthesis, and multimedia interaction. Two complementary prompt pathways were embedded: system-level prompts that enforce curriculum boundaries, ethical constraints, and teacher-in-the-loop oversight, and interaction-level semi-automated prompts that structure live pedagogical dialogue through clarification, confirmation, and guided response generation. Evaluation findings show that the system effectively enacted key Responsible AI principles, including transparency, accountability, cultural responsiveness, privacy, and human oversight. Human expert evaluations further indicated that GenAITEd Ghana is pedagogically appropriate for Ghanaian teacher education, promoting student engagement while preserving educators' professional authority. Identified challenges highlight the need for continued model integration, professional development, and critical AI literacy to mitigate risks of over-reliance.

Human Experts' Evaluation of Generative AI for Contextualizing STEAM Education in the Global South

STEAM education in many parts of the Global South remains abstract and weakly connected to learners sociocultural realities. This study examines how human experts evaluate the capacity of Generative AI (GenAI) to contextualize STEAM instruction in these settings. Using a convergent mixed-methods design grounded in human-centered and culturally responsive pedagogy, four STEAM education experts reviewed standardized Ghana NaCCA lesson plans and GenAI-generated lessons created with a customized Culturally Responsive Lesson Planner (CRLP). Quantitative data were collected with a validated 25-item Culturally Responsive Pedagogy Rubric assessing bias awareness, cultural representation, contextual relevance, linguistic responsiveness, and teacher agency. Qualitative reflections provided additional insight into the pedagogical and cultural dynamics of each lesson. Findings show that GenAI, especially through the CRLP, improved connections between abstract standards and learners lived experiences. Teacher Agency was the strongest domain, while Cultural Representation was the weakest. CRLP-generated lessons were rated as more culturally grounded and pedagogically engaging. However, GenAI struggled to represent Ghana's cultural diversity, often producing surface-level references, especially in Mathematics and Computing. Experts stressed the need for teacher mediation, community input, and culturally informed refinement of AI outputs. Future work should involve classroom trials, broader expert participation, and fine-tuning with Indigenous corpora.

Virtual Reality in Teacher Education: Insights from Pre-Service Teachers in Resource-limited Regions

This study explores the perceptions, challenges, and opportunities associated with using Virtual Reality (VR) as a tool in teacher education among pre-service teachers in a resource-limited setting. Utilizing a qualitative case study design, the study draws on the experiences and reflections of 36 Ghanaian pre-service teachers who engaged with VR in a facilitated lesson for the first time. Findings reveal that initial exposure to VR generated a positive perception, with participants highlighting VR's potential as an engaging and interactive tool that can support experiential learning. Notably, many participants saw the VR-facilitated lesson as a promising alternative to synchronous online learning, particularly for its ability to simulate in-person presentations. They believe VR's immersive capabilities could enhance both teacher preparation and learner engagement in ways that traditional teaching often does not, especially noting that VR has the potential of addressing expensive educational field trips. Despite these promising perceptions, participants identified key challenges, including limited infrastructure, unreliable internet connectivity, and insufficient access to VR equipment as perceived challenges that might hinder the integration of VR in a resource-limited region like Ghana. These findings offer significant implications for educational policymakers and institutions aiming to leverage VR to enhance teacher training and professional development in similar contexts to consider addressing the perceived challenges for successful VR integration in education. We recommend further empirical research be conducted involving pre-service teachers use of VR in their classrooms.

Generative AI as a Learning Buddy and Teaching Assistant: Pre-service Teachers' Uses and Attitudes

This cross-sectional study investigates how preservice teachers in the Global South engage with Generative Artificial Intelligence across academic and instructional tasks while navigating infrastructural barriers such as limited internet access and high data costs. The study surveyed 167 preservice teachers from four teacher education institutions in Ghana. Descriptive statistics and inferential analyses, including multiple and ordinal logistic regressions, were used to examine patterns of GenAI use. Findings show that preservice teachers rely on GenAI as a learning companion for locating reading materials, accessing detailed content explanations, and identifying practical examples. They also use GenAI as a teaching assistant for tasks related to lesson preparation, including generating instructional resources, identifying assessment strategies, and developing lesson objectives. Usage patterns indicate that students in their third and fourth years have significantly higher frequencies of GenAI use compared to those in earlier years. Gender was not a significant predictor of GenAI adoption, in contrast to class level and age. Participants reported positive attitudes toward GenAI, noting that it supports autonomous learning and reduces dependence on peers and instructors for routine academic and teaching activities. However, challenges such as high data costs, occasional inaccuracies in GenAI outputs, and concerns about academic dishonesty were identified as factors that limit more frequent use. The study recommends the integration of GenAI literacy in teacher education programs, with a focus on ethical and responsible AI use to support equitable adoption in the Global South.
