Abstract

Metacognitive knowledge refers to what is known about memory function and the strengths and weaknesses of one's own cognition. This research aims to describe the influence of the problem-based learning model on the metacognitive knowledge and learning outcomes of class IX junior high school students. The research was carried out on Class IX students of Palu City Middle School, the entire population of Class IX consisted of three classes with a total of 45 students. Two classes were used as samples determined based on purposive sampling. Metacognitive knowledge data was obtained through questionnaires and learning outcome data through essay and multiple choice tests. Data analysis used an independent t-test with the help of SPPS version 25.0. The results showed that metacognitive knowledge with conventional learning was significantly lower than the PBL class with a gain of t(25) = 9.289, p < 0.000 and learning outcomes in the conventional class were significantly lower than the PBL class with a gain of t(25) = 4.520, p < 0.000. The conclusion of this research is that there is an influence of the problem-based learning model on the metacognitive knowledge and learning outcomes of class IX SMP students

Abstract

The reason for this review is to portray imaginative reasoning abilities and science-critical abilities to think in middle school understudies by using issue-based learning models. The study was directed at class VIII students at one of Palu City's junior high schools. The population of class VIII consists of five classes totaling 160 students. Purposive sampling was used to select two classes as samples. Data on problem-solving and creative thinking abilities were obtained through essay tests. The instruments used were teaching modules, LKPD, and tests. Information investigation utilized an autonomous t-test with the assistance of SPSS variant 25.0. The findings revealed that the creative thinking skills in conventional classes were significantly lower than problem-based learning classes t(62)=13.56, p<0.001, and problem-solving skills in conventional classes were considerably lower than problem-based learning classes t(62)=14.63, p<0.001. Thus, this study concludes that the creative thinking skills and problem-solving abilities of Class VIII SMP students in science subjects can be empowered by implementing a problem-based learning model.
