This study describes the profile of vocational high school students' metacognitive abilities in mathematics problem solving based on their logical thinking abilities. This research was conducted using descriptive research methods with a qualitative approach. The data was collected using a logical thinking ability test and problem-solving test and. Three students were selected who met different logical thinking stages: the abstract operation stage, the transition stage, and the concrete operational stage. The results showed the subject of the abstract operation stage fulfilled the metacognition stage by re-describing the given problem, knowing the relationship between what was known and what was asked, working on the problem by writing down what was known and asked and entering into the formula and also checking the answer. Transition stage subjects fulfill the metacognition stage by describing initial information and instructions, performing problem-solving steps, and counting to check completed work. The subject of concrete operations fulfills the metacognition stage by stating information and instructions that are non-specific and detailed. The subject has not been able to state the proper steps to ensure the information's conformity with the problem, and the subject sees what is done by calculating.

The main target of the current study is to explain the metacognition of junior high school students with Field Independent (FI) and Field Dependent (FD) cognitive styles in mathematics problem-solving. It should be noted that the statistical population of this study was all junior high school students in the Sragen regency in the 2018/2019 academic year. To reach the research purpose, different instruments such as the cognitive style tests, the problem-solving exercises, and the interview guidance were used. Data analysis was carried out by data collection, data reduction, data presentation, and conclusion. The results indicated that the students who have field-independent cognitive style had high self-confidence that they were able to solve the problem correctly, able to do planning steps, able to make important decisions for themselves, so they can solve the problem properly. Students with FD cognitive style are completely confident that their answer is correct, but they have not yet clarified the steps they need to solve their problems and have not yet focused on their shortcomings in mathematics problem solving, so their task results in mathematics problem-solving incorrectness answer.   Keywords: Cognitive style; Mathematics problem solving; Metacognition

Faktor-faktor kesulitan yang dialami siswa SMA dalam memecahkan masalah matematika kelas XII program IPA yakni: siswa kurang teliti, tergesa-gesa dalam mengerjakan soal, lupa, kurang waktu untuk mengerjakan soal, cepat menyerah, terkecoh, dan cemas. Kata Kunci: analisis kesulitan, pemecahan masalah matematika, kemampuan pemecahan masalah   AN ANALYSIS OF SENIOR HIGH SCHOOL STUDENTS’ DIFFICULTIES IN MATHEMATICS PROBLEM SOLVING BASED AT GRADE XII OF SCIENCE PROGRAM IN YOGYAKARTA CITY Abstract This research aims to describe the locations of the difficulties and the factors of the difficulties faced by Senior High School students in mathematics problem solving in Yogyakarta City. This research is descriptive supported by the quantitative and qualitative approach. The subject of this research was 94 grade XII students of senior high schools in Yogyakarta City. The sample was established from three different schools grouped in the three categories namely high, middle, and low category. The subjects of this research were selected by using the stratified proportional random sampling. The data were collected from the documents and the result of the test and interviews. The data analysis was done by using the qualitative descriptive analysis method with quantitative and qualitative approach that figure out the types and factors of students’ difficulties. The research result suggests that mathematics difficulty locations faced by the research subjects are fact remembering difficulty 3.54%, fact analyzing difficulty 10.18%, concept remembering difficulty 1.33%, concept understanding difficulty 13.27%, concept applying difficulty 11.95%, concept analyzing difficulty 4.42%, procedure understanding difficulty 7.52%, procedure applying difficulty 15.49%, procedure analyzing difficulty 16.37%, visual-spasial concept remembering difficulty 1.33%, visual-spasial understanding difficulty 3.54%, visual-spasial applying difficulty 3.10%, dan visual-spasial analyzing difficulty 2.65%. The factor that make the student difficult in mathematics problem solving was external factor, which is: student that carelessness, answering the question in a hurry, forgetfullness, and having a time limit in doing the work, easily giving up, getting decieved, and being worried.

Preparing high school students for engineering disciplines is crucial for sustainable scientific and technological developments in the USA. This paper discusses a pre-college program, which not only exposes students to various engineering disciplines but also enables them to consider engineering as the profession. The four-week long “Engineering Innovation (EI)” course is offered every year to high school students by the center of outreach, Johns Hopkins University. EI program is designed to develop problem-solving skills through extensive hands-on engineering experiments. A team consisting of an instructor, generally a PhD in Engineering, and a teaching fellow, generally a high school science teacher, closely work with students to pedagogically inculcate basics of core engineering disciplines such as civil, mechanical, electrical, materials, and chemical engineering. EI values independent problem-solving skills and simultaneously promote the team spirit among students. A number of crucial engineering aspects such as professional ethics, communications, technical writing, and understanding of common engineering principles are inculcated among high school students via well-designed individual and group activities. This paper discusses the model of EI program and its impact on students learning and their preparation for the engineering career.
