Abstract
16 items multiple choices measuring 21st-Century Skills based on real laboratory both for temperature and heat transfer topic is developed by capturing the 21st-Century Skills^ framework based on expert validity analysis, developing a blueprint test based on the physics material in school curriculum, analyzing 21st-Century Skills^ assessment items based on the data collected. The built of the framework is done through a literature review (several 21st-Century Skills^ Framework, a study of physics material in the 2013 Indonesian curriculum, and analyzing the contextual problems as project problems that can be developed). First, based on real laboratory, we construct 16 open ended questions to measure 4C in temperature and heat transfer to 30 eleventh grade students in west java in order to capture their answer for multiple answer options. Then the instrument was validated by three experts and revised the item if it needs t be revised. Next step, the revised instruments are tested to a class consist of 50 eleventh students. We analyze its validity using the Content Validity Ratio (CVR) and Content Validity Index (CVI). The CVR Limited stage testing is conducted to determine the empirical validity and reliability of items, level of difficulty, and discriminating power. We found that the test has high validity 0.64, high reliability 0.76, and good discrimanting power 0.68. There is a balance or proportion of the level of difficulty of the questions (easy, medium, and difficult). There are some problems not validated. Therefore, some issues on this proposed standard test should be further improved.
