... stionnaire is needed to detect need analysis of an assessment that can help improving student digital literacy skills. Questionnaires were used to collect expert review data, while cognitive tests were used to collect data on students problem solving skills. Cognitive tests by posttest form was held to find out the progress of students understanding during learning process using the products. The results of content validity by Aiken's V is 0,80. The factor analysis is looked by The Bartlett test value with Chi-squares = 1.604 and significant at 0.659. Therefore, the problem-solving skills assessment from the aspect of content and construction has valid criteria and is suitable for use. The N-Gain test results of students problem-solving skills in the experimental class by 0.3 with a quite effective category higher than the control class of 0.12 with a quite effective category. The results show that the use of assessment of problem-solving skills effectively improved students digital literacy skills.
