Abstract

This research aims to identify the conception of Central Javanese students on fluid pressure. The survey was conducted in Central Java involving 515 participants (eight grade students about 14 years old) consisting of 177 Male and 338 Female. The instrument consists of six questions in a four-tier format about fluid pressure and is distributed via Microsoft Form. The analysis was carried out with Rasch analysis and percentages with six categories of conceptions: CU (Conceptual Understanding)- PP (Partial Plus)- PM (Partial Minus)- NU (No Understanding)- MC (Misconception)- and NC (No Coding). The Rasch analysis show the Cronbach alpha is 0.68 (Enough) and the distribution of students^ conceptions on fluid pressure forms a normal curve. Meanwhile, the percentage are: CU (17%), PP (4%), PM (39%), NU (13%), MC (27%), and NC (0%). This indicate that students^ conceptions are still dominated by PM and MC, thus, the action is needed to overcome.
