“…The research of Castillo et al (2017) related to students' prediction about the state of an object in a liquid. Chien et al (2009), Havu-Nuutinen (2005), Shen et al (2017), Shivakumar (2016), and Teo et al (2017) examined the concepts of properties and states of objects in liquids. In the context of learning, Qonita et al (2019) examined process skills in instilling the concept of floating and sinking.…”

<p style="text-align: justify;">This study aims to explore the pattern of external representation of suspending objects in a static fluid. The study used a qualitative descriptive method involving 57 elementary, junior, senior school, and university students. Data collection implemented a 30-item test covering the dominant context of suspending and partially floating and sinking. Some of phenomenographic steps were adapted in data analysis. Based on the data analysis, it can be concluded that there is a dominant external representation pattern, where there is a simplification of the depiction of suspending objects. Suspending position tends to be locked in a limited area, namely in the middle of the depth of the liquid. In the context of suspending objects' cuts, the cuts were generally represented by an upward shifting pattern. Factors that influence the pattern of representation are the involvement of intuition in conceptualizing the phenomena presented, and the conceptual aspect of density has not been integrated into the reasoning process for compiling external representations, both diagrams, and texts. Research limitation is presented in this article.</p>

“…Similarly, Havu-Nuutinen (2005), Chien, Hsiung and Chen (2009), Shen, Liu and Chang (2017), Shivakumar (2016), and Teo, Yan and Ong (2017) examined the concept of the object properties and state in liquid fluid on floating and sinking objects. Castillo, Waltzer and Kloos (2017) carried out a study focusing on predictions related to the sinking of an object.…”

This study aims to develop a test that can be used to explore mental models and representation patterns of objects in liquid fluid. The test developed by adapting the Reeves's Development Model was carried out in several stages, namely: determining the orientation and test segments; initial survey; preparation of the initial draft; try out; expansion of coverage; expert validation; trial and proving validity-reliability; and test finalization. The content and construct validity were determined by involving two experts as raters. The test reliability was determined using Cohen's Kappa (к), which involved 62 students and combined the test-retest and inter-rater methods to determine the consistency of students' responses. The developed test consists of 30 items covering the context of floating, sinking, and hanging objects. The hanging objects are dominant context of the test. The results showed that in the development process, the test has very good validity, and high reliability. The test can be used to explore mental models and external representation patterns on students in elementary, junior, senior high schools and undergraduate. Furthermore, limitations of the test are also presented in this paper.
