Abstract
Algebraic reasoning is the process of solving algebraic problems through investigation and drawing out conclusions to prove the truth. In the preliminary study, it appears that students are still experiencing analytical errors when solving algebraic problems. One of the studies that discusses the source of this error is the pseudo-thinking theory. This study aims to obtain a description of algebraic reasoning in terms of pseudo-thinking theory in grade VII students at one of the Madrasah Tsanawiyah in Riau. This research is qualitative research that uses a phenomenological approach. The subjects of this study were 11 grade VII students. The supporting instruments in this study consisted of- tests, interview guidelines and observation sheets. The results of this study are- 1) In general, the subjects experienced pseudo-analytics error conditions within each indicator of algebraic reasoning. 2) There is a subject who experiences pseudo-thinking errors on two indicators of algebraic reasoning. 3) There is a subject who experiences two types of pseudo-thinking errors on algebraic reasoning indicators.
