STEM-based learning innovations have been massively developed especially related to 21st Century skills. This study was done to explore a relationship between creative thinking and science achievement through the implementation of integrated STEM-based module on Reproduction topic. A quasi-experimental study involved pretest-posttest non-equivalent group design with sample of 60 eighth graders from a boarding school in Baling, Kedah, Malaysia. The samples was divided into two groups - 30 students of treatment group and 30 students of control group. The data were collected from pre-post-Reproduction Test Questions (RTQ) scores and pre-post-Creative Thinking Test Questions (CTTQ) scores. Pearson Correlation and one-way ANOVA at a significance level p < .05 were performed in analysing data. Findings reveal no statistically significant relationship between creative thinking and science achievement for both treatment group (r = .220, p = .243) and control group (r = .308, p = .098). Besides, there is a statistically significant and moderate and positive relationship between creative thinking indicator of fluency and science achievement (r = .463, p = .010) of the treatment group. In conclusion, general finding is an evidence that between creative thinking and science achievement shows a consistency in whatever teaching strategy implemented. In which, educators need to realize that academic achievement does not necessarily be a necessity in shaping one’s creativity. Therefore, further study is needed to investigate the relationship between these variables in the execution of STEM teaching and learning so that the findings can be generalized to a larger population.

The purpose of this study is to examine the contributions of the Celik STEM Module developed on pupils’ creative thinking in the science classrooms. A quasi-experimental study involved a non-equivalent control group with a sample of 60 eighth-graders aged 13 years old from a boarding school in Baling, Kedah. The sample was divided into two groups; 30 pupils of the treatment group and 30 pupils of the control group. Data were collected from pre-post-creative thinking test (CTT) scores. One-way analysis of covariance at a significance level p < .05 was performed in analyzing the data. After adjusting for pretest scores, there was a significant difference between the two sample groups on posttest scores on the CTT, F (1,57) = 16.639, p = .000, partial eta squared = .226. Besides, there was a significant and moderate relationship between the pretest and posttest scores on the CTT, as indicated by partial eta squared = .082. In conclusion, teaching and learning of the Reproduction topic through STEM integration applied in the module is better than regular instruction. The results of the present study showed that this alternative teaching method has been proven effective in developing and empowering pupils’ creative thinking.
