Abstract
Most teachers, in their teaching and learning practices, tend only to assess lower order thinking skills so that higher order thinking processes, including creative thinking, is rarely done. This study aimed to examine the increase of students’ mathematical creative thinking and motivation through Problem Based Learning (PBL) model using GeoGebra. This research employed an experimental method with randomised pre-test post-test control group design. The sample of the study were two classes of Year 11 students in one of the senior high schools in Lhokseumawe, Aceh, Indonesia. The data were analysed using t-test. The result showed that there was an increase of students’ ability of mathematical creative thinking and motivation taught using the PBL model with GeoGebra; it was higher than those who are taught using PBL model without the software. GeoGebra assisted learning is a useful tool for constructing mathematical concepts such as geometry and making positive contributions to improve mathematical creative thinking skills. The use of GeoGebra is highly recommended to enhance mathematical learning as it shifts mathematics learning to be more fun and interesting.

Abstract
Student problem-solving skill is the focus of mathematics learning. Students are expected to have specified skills to solve mathematical problems. This study aimed to describe students’ mathematical problem-solving skills at a junior high school in Calang. The method used in this study was qualitative. Two year-9 students were selected by purposive sampling as the participants. Data collection was conducted using a test and interview. The test comprised mathematical problems, aiming to determine students’ ability to solve the problems. The interview was conducted to verify the students’ answer, as some indicators were not fulfilled without the interview. The results showed that the students’ mathematical problem-solving skills were poor. The students did not understand the problems well. They had a plan for solving the problems, but it was not in line with the concept. Their problem-solving implementation was not in order, and they did not recheck their solution. This finding implies that teachers need to pay attention to students’ skills in solving non-routine problems. Teachers should use contextual word problems that are directly related to students’ daily life so that students feel familiar with the questions.

Abstract
21st-century education demands critical thinking, problem-solving, communication, and collaboration skills, as well as creativity and innovation. National Council of Teachers of Mathematics has set five standards on student mathematical skills required by students; one of them is problem-solving. Programme for International Student Assessment showed the lack of Indonesian student problem-solving skills. There is a need for revamping the education system to improve the quality of human resources so that Indonesian students’ problem-solving skills can be better. This qualitative descriptive research aimed to examine the mathematics problem-solving skills of vocational high school students. The research subjects were 22 vocational high school students and the data collection involved a problem-solving test and interview. The results showed that out of 22 subjects (11 groups) in the research, no subject achieved the ‘very good’ and ‘good’ category of problem-solving skills. Four groups had ‘adequate’ problem-solving skills and seven groups had ‘poor’ problem-solving skills. The results showed that students had difficulty in solving problems because they did not understand the problems, and thus they can not solve problems. They were also not accustomed to non-routine problems and had a lack of understanding of designing mathematical models and connecting mathematics to the real world.

Abstract
Higher order thinking skills are important for students to help them solve various problems faced over time. Several previous studies on higher order thinking skills have been conducted, but no one focuses on higher order thinking skills at junior high school level in the regions where the average of computer-based national exam results are relatively low in Indonesia. The purpose of this study is to find out categories of and describe students’ higher order thinking skills in solving PISA problems based on determined indicators. This study used a descriptive qualitative methodology. The instruments used in this study were the PISA test and interview guide. The participants were students in the age range of 15 years randomly selected from several junior high schools in Banda Aceh. At this age, the students’ knowledge and abilities could be assessed. Data were collected from the test, interview and documentation that involved 40 participants. This study found that, generally, students had low level of higher order thinking skills, and there were no students who achieved a high level. Therefore, it is recommended to address this issue by developing and improving the students’ abilities that require higher order thinking skills so that the students are able to apply their knowledge and skills to solve new problems and implement them in real life situations.
