This study aims to develop a performance assessment instrument for Make up Training Subject in Beauty Education Program by appropriate validity and reliability procedure in thedevelopment of the assessment instrument as the assessment process and products. Thisresearch is a development research (R&D). The research focuses on the development ofassessment instrument for Makeup Training Subject. The aspects of research, data sources, techniques and instruments/data collection instrument, and validation and reliability of theinstrument used in the study conducted by interview, observation, and literature and documents.The data of this study is quantitative data, which was statistically analyzed due to relevant empirical testing (validation of instruments) that includes testing and content validity andinternal validity. Descriptive analyzes were undertaken to describe the research data. The results showed: 1) The design of the instrument Makeup Training Subject are developed through theneeds analysis. It is done through literature review and study of the course competencies byengaging a team of researchers. This study resulted in the instrument guidelines and assessment instrument completed with its scoring rubrics. The instrument comprising: a step of validityassessment is done through the stages: experts judgment, empirical tests to prove the validityand reliability of the instruments assessment. All the performance test instrument developed is

School is a space where learning mathematics should be accompanied by the student’s preferences; however, its valuation in the classroom is not necessarily the same. From a quantitative approach, we ask from the mathematical thinking styles (MTS) theory about the correlations between preferences of certain MTS and mathematical performance. For this, a valid test instrument and a sample of 275 16-year-old Chilean students were used to gain insight into their preferences, beliefs and emotions when solving mathematical tasks and when learning mathematics. The results show, among other things, a clear positive correlation between mathematical performance and analytical thinking style, and also evidence the correlation between self-efficacy, analytical thinking and grades. It is concluded that students who prefer the analytical style are more advantageous in school, since the evaluation processes have a higher valuation of analytic mathematical thinking.

Abstract Consistency of upper-tropospheric water vapor measurements from a variety of state-of-the-art instruments was assessed using collocated Geostationary Operational Environmental Satellite-8 (GOES-8) 6.7-μm brightness temperatures as a common benchmark during the Atmospheric Radiation Measurement Program (ARM) First International Satellite Cloud Climatology Project (ISCCP) Regional Experiment (FIRE) Water Vapor Experiment (AFWEX). To avoid uncertainties associated with the inversion of satellite-measured radiances into water vapor quantity, profiles of temperature and humidity observed from in situ, ground-based, and airborne instruments are inserted into a radiative transfer model to simulate the brightness temperature that the GOES-8 would have observed under those conditions (i.e., profile-to-radiance approach). Comparisons showed that Vaisala RS80-H radiosondes and Meteolabor Snow White chilled-mirror dewpoint hygrometers are systemically drier in the upper troposphere by ∼30%–40% relative to the GOES-8 measured upper-tropospheric humidity (UTH). By contrast, two ground-based Raman lidars (Cloud and Radiation Test Bed Raman lidar and scanning Raman lidar) and one airborne differential absorption lidar agree to within 10% of the GOES-8 measured UTH. These results indicate that upper-tropospheric water vapor can be monitored by these lidars and well-calibrated, stable geostationary satellites with an uncertainty of less than 10%, and that correction procedures are required to rectify the inherent deficiencies of humidity measurements in the upper troposphere from these radiosondes.
