Abstract

Statistical literacy is a key ability expected of citizens in information-laden societies, and is often touted as an expected outcome of schooling and as a necessary component of students' numeracy and literacy. The facts show that the statistical literacy ability of Indonesian students is still in an alarming category and Indonesian students for junior high school have not been able to compete internationally in the statistical literacy. This qualitative descriptive research was conducted to describe junior high school students’ ability and difficulties in basic skills of statistical literacy. Data were collected from 6 students of 8th grade in one of junior high school in Aceh, Indonesia through test and interviews. The results clearly show that students’ statistical literacy are still in low category. Students are good in understanding the data but they have limited understanding of the data presentation concept. Students have difficulty in using the principle of presenting the data into the pie chart. Many steps of presenting the data are not complete. From this study can be concluded that students’ basic skills of statisical literacy has not been satisfied. Therefore, mathematics learning process in data presentation concept should be improved.

Abstract

To describe students' lateral mathematical thinking ability on trigonometricproblems, we conducted a research on 30 students (15/16 year old) in West Java, Indonesia.This research is a qualitative descriptive research and data collection technique is written testwith 3 description questions. The test results were analyzed using three indicators of lateralmathematical thinking ability, (1) finding different ways of looking at things, (2) identifyingthe dominant ideas of the problems, and (3) associating concepts / ideas into several strategiesmay be true or false. Results of the study showed that: (1) almost one-third of the number ofstudents can look for different ways of looking at a problem, (2) more than one-third ofstudents can identify the dominant ideas of the problem, and (3) more than half students canassociate a concept / idea so that it becomes some strategies that may be true or false. Based onthe result of research, it is seen that most students do not have good lateral thinking ability insolving trigonometric problems.
