The extent of use of practical work by secondary school biology teachers in public schools in Anambra State of Nigeria was investigated. The design adopted was descriptive survey. The population of the study comprised all the biology teachers in Anambra State. The sample for the study was made up of 221 biology teachers selected through multi-stage sampling. The instrument for data collection was researcher constructed questionnaire titled Practical Work Questionnaire. The instrument was subjected to validation by three experts while reliability index of 0.86 using Cronbach Alpha coefficient was obtained. The data collected were analysed using mean. The findings of the study showed that among others that the ways by which the use of practical work by biology teachers in teaching biology can be enhanced include continuous supply of materials, inspection of laboratories, use of alternatives to practical, project work, outdoor practical, field trips/excursions, improvisations, use of simulations, invitation to experts in subject area, and alternative power supply. The findings also showed that schools have materials and equipment for practical works which are used by biology teachers to a moderate extent. The study recommended that government should also create a separate department under the minister of education, charged with the responsibility of carrying out occasional and routine check of school practical works to ensure they are used for teaching biology.
