The curriculum support materials used in an instructional process may influence assessment and achievement of learners. Curriculum support materials are both print and electronic in nature. One of the main electronic curriculum support materials used in schools is interactive digital content. In recent years, there has been rapid expansion in curriculum digital content access and utilization in Kenyan schools. However, little has been done to establish how utilization of curriculum digital content in the instructional process influences learners’ assessment and achievement. The study reported in this paper therefore investigated the influence of curriculum digital content utilisation on secondary school learners’ assessment and achievement in Biology. It was guided by two specific objectives including to: investigate the influence of the utilisation of Biology digital content on learners’ assessment and examine the influence of the utilisation of Biology digital content on learners’ achievement. A mixed methods approach that employed triangulation design was used in this study. Data was obtained from fifteen Economic Stimulus Programme-ICT phase 1 secondary schools in Nairobi County. Three instruments including Biology teacher questionnaire, learners’ focus group discussion guide and documents analysis sheet were used for data collection. The collected data was analyzed using both descriptive and inferential statistics and presented in form of notes, tables, and graphics. This study found out that most assessment aspects improved with curriculum digital content utilization. In addition, utilisation of curriculum digital content had a positive influence on the achievement of secondary school learners in Biology. The study recommended that all schools, and not only ESP-ICT schools, be provided with proper infrastructure to enable learners and teachers access and utilize curriculum digital content in the instructional process. This would enhance assessment modes and learners achievement in secondary schools in Kenya.

The quality of educational support materials utilized in schools contributes greatly to the quality of education that is delivered during an instructional process. In recent years, there has been rapid expansion in digital content development, dissemination and access in schools. Many initiatives geared towards development and provisions of digital content to schools in Kenya have been witnessed. However, little has been done to ensure that the educational digital content design aspect such as user interface is appropriate for the instructional process. This study therefore investigated the effect of the user interface on the utilization and efficacy of educational digital content among secondary schools in Kenya. The study was guided by three specific objectives including to: analyze the layout of the various components of educational digital content in secondary schools; examine the navigational tools in the educational digital content and assess the effect of user interfaces on the utilization of educational digital content in secondary school. A descriptive survey design was used for the study which involved fifteen Economic Stimulus Programme phase 1 secondary schools in Nairobi County. Three research instruments, that is, teacher questionnaire, learners’ focus group discussion guide and digital content analysis sheet were used to collect the required data. The collected data was analyzed through descriptive statistics and presented in form of notes, tables, and figures. The study established that there were issues with interface and navigational tools in educational digital content user interface which affected content utilisation and consequently its efficacy. To address the design issues of the content, the study recommended that developers design appropriate user interfaces with adequate and standard navigational tools that will make educational digital content navigation and utilization easy for users.
