The study aimed at describing: (1) the differences of physics learning achievement of the students learnt by cognitive conflict strategy and those learnt by conventional model, (2) differences of physics learning achievement of the students having higher critical thinking from those having lower critical thinking, (3) interactive effect between cognitive conflict strategy and conventional instructional model and ability of critical thinking towards physics learning achievement. The study was conducted at SMP Negeri 2 Nusa Penida in 2011/2012, by utilizing quasi-experimental method, with 2x2 factorial and post-test only control group design , involving the population of the students class VII. The samples were determined by using simple random sampling. Cognitive Conflict strategy was considered as an independent variable, while ability of critical thinking was considered as moderator independent variable or psychological variable, learning achievement was considered as dependent variable. The data were analysed by using two-tailed ANAVA supported by SPSS 13.00 for windows. The results indicated that (1) there was a different physics learning achievement of the students learnt by cognitive conflict strategy and those learnt by conventional model with F=20.882 with signification figure of 0.001 (p<0.05), (2) there was no different physics learning achievement of the students having higher level of critical thinking from those having lower level of critical thinking with F=1.437 with significant figure 0.234 (p<0.05) (3) there was an interactive effect between cognitive conflict strategy and conventional model of instruction and critical thinking ability towards physics learning achievement with F=19.631 with significant figure 0.001 (p<0.05). Based on the findings, the teachers were recommended to use this instructional model based on the philosophical of constructivism as an alternative to improve the students learning achievement.
