The mathematical problem mostly has been involved in the measurement of student ability according to study objectives and data needs. In this study, geometric-function problem has been used to data collection, analyzed problem type, and students thinking levels based on their completion. The sample of this study was three student high school in a science programme in the region of West Jakarta who selected purposively. Based on data analyzed, the result was found that students view the problem as the task constructed algebraic function formula. The completion and solution that have been shown by students, categorized the problem in open-ended type. The finding of mathematical thinking levels analysis there was a different complexity of thinking process between students because the number of concepts applicate. According to van Hiele theory, student's geometry thinking levels was on abstraction level minimally, and the problem is not relevant for deduction thinking level criterion. For the analysis result about algebraic thinking levels, by the structure of the observed learning outcome (SOLO) taxonomy, students at the levels between relational and extended abstract. Students in these levels was a student high ability so it is appropriate with the background of the sample selected.

Assessment in learning is an important aspect to analyze the learning progress. Nowadays, the assessment runs a shifted paradigm from measuring in higher-order thinking aspects to performance assessment. This study aims to develop an assessment instrument based Authentic Scienti_c Inquiry Assessment (ASIA) in measuring the laboratory skills. The laboratory skills consist of_ve skills categories, they are safety skills in the laboratory, experiment management, measuring skills, collecting data, and interpreting skills. From those skills, we derive 20 aspects. We used 4D methods in developing the instruments, define, design, develop, and disseminate. The results of construct validation and content show that the instrument is valid and reliable. We perform the effectivity test and gain the tcount = 25281; ttable = 1,708 with significance level less than 0,05. We also perform a questionnaire for the lecturers and laboratory assistant that shows 85% positive response, 11% of negative response, and 4% of abstance. We can conclude that our instrument is effective to measure the laboratory skills.
