Abstract

Growing evidence indicates that COVID-19 has influenced student achievement. In core subject like physics, there are upsetting indications that in some grades students could be falling further behind pre pandemic expectancy. Concerning to the pandemic worrying effects, the major purpose of this paper is to explore the grade-11 student understanding about dynamics fluid following online learning during the corona virus pandemics. The four-tier diagnostic instrument was administered to a total of 142 grade-11 students. Cronbach alpha reliability coefficient was estimated for the four-tier diagnostics test at 0,79. Item validities ranged from 0,442 to 0,18. Data was analysed by computing the percent of correct answers at each tier for every item and the percent of answer to alternative conceptions for each category. Dealing with dynamics fluid concepts, 75% students had alternative conceptions, 21% students did not know the concepts, and 4% students were lack of knowledge. The high percentage of alternative conception related to continuity equation dan Bernoulli^s principle.
