    RELATIONSHIP BETWEEN PEDAGOGICAL PRACTICES AND OUTCOME OF SCIENTIFIC TRAINING ON BIOLOGICAL EVIDENCE MANAGEMENT IN NAIROBI COUNTY, KENYA
    (Chuka University, 2023-10) ITHAWA MARTIN MWONGERA
    The criminal justice system in Kenya like many developing countries is faced with the challenge of increase in crime rates with low convictions due to weak cases presented in court. This in most cases, has been attributed to minimal, or lack of relevant training in biological evidence management thus inadequate knowledge and skills in the management of biological evidence found at a crime scene. The quality of scientific training received by the Crime Scene Investigators and Crime Scene Management trainees determine the extent to which they effectively manage biological evidence at a crime scene. Empirical literature that could illustrate the link between pedagogical practices and outcome of scientific training on biological evidence management is however limited. This research therefore, focused on the relationship between pedagogical practices and outcome of scientific training on biological evidence management in Nairobi County, Kenya. The researcher sought to establish the content for scientific training on biological evidence management, methods of instruction, instructional resources and assessment methods for scientific training on biological evidence management. The study adopted descriptive research design with a sample size of 132. Participants included 87 Crime Scene Management trainees, 33 Crime Scene Trainers and 12 Quality Control Officers. Stratified and simple random sampling procedure was applied on Biological Evidence Management Trainees and their trainers. Purposive sampling was used to select the Quality Control Officers. Interview schedule was used to collect data from Quality Control Officers and structured questionnaires used for both Biological Evidence Management Trainees and their trainers. A pilot study was conducted at National Police College (B Campus) on 10% of the sample size. Reliability of the instruments was tested using split-half method. Cronbach’s Alpha coefficient of 0.825 to 0.965 for Biological Evidence Management Trainees questionnaire was obtained. The reliability coefficient for Trainers’ questionnaire ranged from 0.876 to 0.950. The quantitative data was analyzed by use of descriptive and inferential statistics with the aid of Statistical Package for Social Sciences (SPSS) version 25.0. Qualitative data was analyzed thematically and research hypotheses was tested at 95% level of confidence. The study is meant to inform curriculum planners in collaboration with Directorate of criminal investigations on the need of improvement of scientific training on biological evidence management curriculum. The observations of the research are to help the Interior and National Administration ministry on the need to avail and improve the resources required by DCI for Scientific Training. The content was sufficient though there were few lessons allocated thus inadequate coverage of content. Lecture was most preferred implying preference of teacher centered methods. Printed materials were the most preferred instructional resources, however resources, such as CSI simulations were integrated at relatively low rates. Findings from both BEM trainees and trainers indicated that except for practical and oral presentations, there was minimal use of high order formative assessment methods. Enough lessons should be allocated for adequate coverage of content, CSI trainers to use instructional methods and integrate more instructional resources which are learner centered.
