Abstract
The study determined teachers' knowledge and application of digital assessment in STEM education. It was carried out in Nsukka Education Zone, Enugu State, Nigeria. Guided by four research questions, the study adopted descriptive survey design. The population of the study included all 220 STEM teachers (Chemistry, Physics, Biology and Mathematics teachers) in the education zone. Multistage sampling procedure was then used to sample STEM teachers from the three LGAs which make up the zone. The sample size for the study was 88 STEM teachers, determined through the Taro Yamane sampling formula. Teachers' knowledge and application of digital assessment questionnaire, developed by the researchers, was used to collect data for the study. Data collected were analysed using SPSS 25 version. Frequency, Mean and Standard deviation was used to answer the research questions posed to guide the study. Findings revealed that STEM teachers were not aware of most digital assessment tools but applied the ones they know to a low extent in STEM teaching. The study hence concluded that there was a low level of teachers' knowledge and application of digital assessment tools. The study recommended that in-service training be organized for STEM teachers in order to improve the trend and to keep abreast with modern digital assessment tools.
