Preliminary study of authentic assessment that focus on self assessment and portfolio assessment using problem based models in senior high school

The use of process-based assessment instrument by teachers is not yet implemented effectively. Most of teachers have used written test and oral test in the form of mid-semester and end-semester test well, but the process aspects such as skills and attitudes have not been implemented optimally. Therefore, it is necessary to do research to analyze the assessment process provided by teachers. This initial research was conducted in one of the high schools in Padang City, namely SMAN 15 Padang. Data analysis techniques used are tabulation and percentage. The data obtained from an assessment process conducted by teacher are around 80% results-based assessment and 20% process-based assessment, wherein the results-based assessment are more dominant than the process-based assessment. Skills indicators assessed in this study include: doing practicum (K1), conclude the results of the practicum (K2), make a presentation (K3), apply new knowledge (K4), and solve problems and questions (K5). While attitude indicators assessed in this study include: curious (A1), confidence (A2), responsibility (A3), discipline (A4), conscientious (A5), cooperation (A6). Suggestions raised based on the results of preliminary research that process-based assessment especially skills and attitudes need special attention by conducting further research to develop a process assessment instrument
