This research surveyed 11 purposely sampled Bindura University of Science Education (Zimbabwe) Bachelor of Science Education Honours Part III pre-service science teachers' use of improvised and virtual laboratory experimentation in science teaching. A self-designed four-point Likert scale twenty-item questionnaire was used. SPSS Version 10 was used to analyse data. Frequencies, means, standard deviations and standard error means were used to systematically evaluate variables on pre-service teachers' use of the technological resources. Most pre-service teachers (90.9%) used improvised laboratory experimentation in their teaching. However, although the pre-service teachers knew the value and benefits of virtual experimentation, they did not use the technology in their teaching. The methods course (Pedagogics in Science Teaching) for the pre-service science teachers should be more focused on specific instructional uses of technology and technical skills rather than familiarisation with technology, to effectively integrate technology in their teaching to support student-centred learning.
