Therefore, this quasi-experimental study aimed to enhance preservice elementary teachers’ CTS and SPS by using Inquiry-Based Laboratory Instruction (IBLI). <span lang="EN-US" style="font-size:8.0pt;line-height:107%; font-family:"Book Antiqua",serif;mso-fareast-font-family:Calibri;mso-bidi-font-family: "Times New Roman";mso-ansi-language:EN-US;mso-fareast-language:EN-US; mso-bidi-language:AR-SA"> Method: A pretest-posttest control group design was executed. A total of 43 students who attended Teaching Science in Elementary School-II Laboratory  Course at the Muhammadiyah University of Ponorogo were divided into two groups using cluster random sampling. The experimental group ( n =21) was taught by using IBLI, while the control group ( n =22) was taught by using traditional laboratory method. The Oliver-Hoyo Rubric for Critical Thinking (OHRCT) and the Observation Checklist for SPS (OCSPS) were administered. The data were then analyzed by using normalized gain score and Mann-Whitney U test at significance level .05. Findings: There was a significant difference in terms of CTS and SPS between control and experimental groups in favor of experimental group students. It was found out that gained CTS score of control and experimental group students was .58 and .80, while gained SPS score was .60 and .81, respectively. It can be highlighted that IBLI had a significant effect on preservice elementary teachers’ performance compared to the conventional group. <o:p> </o:p> <div style="text-align: justify;"> Implications for Research and Practice: The findings suggest that IBLI is considered as the effective method to foster CTS and SPS of preservice elementary teachers.
