To use CIPP for e-learning in educational leadership, you need to define the purpose, scope, and criteria of your evaluation, and then collect and analyze relevant data for each of the four aspects. For context evaluation, you need to identify the needs, goals, and expectations of your target learners, educators, and stakeholders, and how they align with the standards and objectives of your e-learning program or course. You also need to consider the external factors and challenges that may affect your e-learning program or course, such as technological, legal, ethical, and social issues. For input evaluation, you need to evaluate the quality, adequacy, and suitability of your e-learning resources, such as content, materials, tools, platforms, and support services. You also need to evaluate the design, development, and delivery of your e-learning program or course, such as the curriculum, pedagogy, assessment, and feedback methods. For process evaluation, you need to monitor and document the progress, performance, and participation of your learners and educators, and how they interact with each other and with the e-learning environment. You also need to identify and address any problems, issues, or gaps that may arise during the e-learning program or course, such as technical glitches, communication breakdowns, or learner dissatisfaction. For product evaluation, you need to measure and evaluate the outcomes, results, and impacts of your e-learning program or course, such as the achievement of learning objectives, the satisfaction of learners and educators, the improvement of skills and competencies, and the contribution to educational leadership practice and research.
