ABSTRAK

This research done caused low mathematics students’ achievement. Particularly, many students have difficulty in solving Three Dimensional question. The aim at this research was describe kinds of students’ error at class X.1 SMAN 3 Lubulinggau in solving Three Dimensional questions and the caused factors. The type at this research was descriptive research with the subject students of class X.1 SMAN 3 Lubuklinggau in academics years 2015/2016. The data collected through observation and interview. Based on the result from analyzing the data, it was conclude that kinds of students’ error class X.1 SMA NEGERI 3 Lubuklinggau in solving Three Dimensional questions were: 1) Error facts 63,75%, 2). Error concept 56, 75%, 3). Error operation 61.75%, and 4). Error Principe 71.5%. The cause factors were: 1) The student forgot and lacks accuracy in writing the answers, completes the answers, calculation operations, and the student forgot to determine the rules of cosine; 2) Students did not understand the concept to solve the questions of the three dimensions and the students perform calculations based on reasoning rather than on the concept; 3) Students have difficulty in illustrating / abstracting images from geometry conditions which asked so the students took wrong conclusions; And 4) Students did not understand the triangle in the cube or limas space so the students wrong in stating the Pythagoras theorem.
