Logical thinking ability in scientific practicum is necessary to maintain the quality of education program of science student teacher. This study aims to assess logical thinking skills through practicum performance assessment instruments. This study describes the aspects of logical thinking as follows; formulating problems, developing hypotheses, collecting data, analysing data, constructing discussion, and drawing conclusions. The instrument validation was carried out in two ways. The education evaluators measured the construct validity, and the calculation of empirical validity was performed statistically using SPSS. Items for supporting logical thinking in data collection was invalid (sig > 0.05), while items in problems formulation, hypotheses development, data analysis, discussion construction, and conclusion drawing were valid (sig < 0.05). The new finding in this study is a valid evaluation instrument of practicum performance to measure logical thinking ability. It can be utilised by science educators of various levels to enhance the science practicum quality. © Serials Publications.
