Abstract

This study aims to describe the ability of spatial geometry of class XI MIPA 1 SMA Negeri 2 Jember in terms of David Keirsey's personality type. Spatial ability in this study is the ability to understand the world of space based on elements of spatial abilities which include: spatial perception, mental rotation, and spatial visualization. This type of research is a descriptive study with a qualitative approach. The data collection method in this research is questionnaire, spatial test, and interview. Then, based on the results of the test and interview analysis, it was found that the Guardian students could fulfill all spatial indicators. Artisan students in imagining and rotating spaces can think quickly and answer questions correctly, compared to guardian and idealistic students. Idealistic students in the ability to see the surface of the unit cubic structure more than the point of view (from the front, right side, and top) cannot describe it precisely. Meanwhile, rational students on the mental rotation element for the first indicator are still unable to rotate a spatial shape and can imagine the rotation or rotation of a spatial shape accurately.

Abstract

Research to describe whether the results of the assessment in the affective domain affect student learning outcomes on the subject matter of Probability Statistics. One of the assessments of the affective domain is attitude assessment. The research approach is a quantitative research with an analysis of the research subject of 100 students who have taught the Probability Statistics course. This research was conducted using an instrument in the form of an attitude scale questionnaire based on a Likert scale consisting of 22 questions with answers to questions including: Always (SL) points 5, Often (SR) points 4, Sometimes (K) points 3, Rarely (JR) point 2, and Never (TP) point 1 which is based on the attitude scale instrument grid in the form of a checklist. The indicators measured on the attitude scale are interest, curiosity, attention in learning and self-confidence. The method of analysis in the form of a correlation survey is to see the influence of the affective domain on student learning outcomes. From the results of the research, it is known that the effect of learning outcomes based on student attitudes is the most prominent due to the interest and confidence of students who are in charge of the Probability Statistics course. For curiosity and attention in learning do not have a direct effect on learning outcomes.
