This study aims to analyze the errors of junior high school students in solving integer story questions. The type of research that will be used is descriptive qualitative. 24 students of grade VII SMP were made participants. The instruments used were in the form of integer story questions and semi-structured interview sheets. The data collection procedure began by giving test questions to participants. The work of students who experience a lot of mistakes is analyzed using the Newman or NEA (Newman Error Error) procedure. Obtained three groups of students who experienced the same error in solving integer story questions in writing. One student was taken from each group to represent what is hereinafter referred to as subject 1 (S1), Subject 2 (S2), Subject 3 (S3). The results obtained indicated that in completing the whole number story problem, S1 did not understand the overall meaning, so there was some information that was missed on the purpose of the problem or question. S2 understands the problem contained in the problem, but cannot write information in mathematical form, and does not do calculations correctly. S3 could not perform mathematical calculations or procedures correctly. The researcher concluded that students who experience errors in reading problems would experience four other errors, namely errors in understanding and problem transformation, then students would also experience errors in process skills and errors in writing the final result.

This study aims to develop a valid, practical, and effective ACPAE learning model that can restore studentsâ€™ self-efficacy. The development of the ACPAE model is a modification of PACE learning by adding one stage in the form of action. Less varied learning models result in students being bored when learning mathematics is taking place. For mathematics learning to run more actively and achieve learning objectives, the learning model to be applied must be appropriate. Students perceive mathematics as a difficult and tiring subject. This results in decreased studentsâ€™ self-efficacy. The data analysis technique was obtained from the validity test questionnaire, practicality test, and effectiveness test results with 15 junior high school students as the subject. The results showed that the ACPAE model of learning could increase students' activeness in learning. The level of self-efficacy of students was shown by daring to interact in group discussions and appearing confident in front of the class. Based on the results of the validity test, the ACPAE learning model module obtained a value of 78.8%, for Lesson Plan obtained a value of 76.6%, for Student Worksheet obtained a value of 76.3%, for student response questionnaires received a value of 88.3% while for the percentage of learning completeness by 86.6%. So that when viewed from the assessment criteria, the ACPAE model is very appropriate to be used as a variation of the mathematics learning model.
