Abstract
The 16 multiple choice items measuring 21st Century Skills based on real laboratories for both time and the topic of measurement physics were developed by capturing the 21st Century Skills framework based on expert validity analysis, developing blueprint tests based on physical materials in the school curriculum, analyzing 21st Century Skills assessment items based on collected data. The construction of the framework is carried out through a literature review (several 21st Century Skills Frameworks, the study of physical materials in the Indonesian curriculum 2013, and analyzing contextual issues as project problems that can be developed). First, based on a real laboratory, we built 16 open-ended questions to measure time measurements and 4C physics to 1stgrade 0 studentsin West Java to capture their answers to multiple answer options. Then the instrument is validated by the expert and revises the item if it does not need to be revised. The next step is to validate the contents by using a judgment sheet that has been created to be given to the validator. This validation sheet to state the suitability of the problem item with the 21st century skills indicator. The material provided contained 2 subjects for the first test has a low validity of 0.58,high reliability of 0.73,and good diskrimanting power. the first test has a low validity of 0.72, High reliability 0.83,and good diskrimanting power. There is a balance or proportion of the difficulty level of the question (easy, moderate, and difficult). There are some issues that are not validated. Therefore, some of the issues on this proposed standardized test should be further improved.
