Susac, Ana; Bubic, Andreja; Planinic, Maja; Movre, Marko; Palmovic, Marijan – Physical Review Physics Education Research, 2019
Typical physics textbook problems often include supportive diagrams that visualize the physical situation although the potential benefits of providing such diagrams is not yet fully established. We used eye tracking to explore the role of supportive diagrams in problem solving. Including a supportive diagram with the text of the problem improved…

Mešic, Vanes; Neumann, Knut; Aviani, Ivica; Hasovic, Elvedin; Boone, William J.; Erceg, Nataša; Grubelnik, Vladimir; Sušac, Ana; Glamocic, Džana Salibašic; Karuza, Marin; Vidak, Andrej; Alihodžic, Adis; Repnik, Robert – Physical Review Physics Education Research, 2019
Even graduate physics students have many misconceptions about basic wave optics phenomena. This suggests that there is much room for improvement of the traditional wave optics curriculum. An effective way for initiating a curriculum change is to reconsider and revise the expected learning outcomes and corresponding assessment instruments. By…

Susac, Ana; Planinic, Maja; Klemencic, Damjan; Sipus, Zeljka Milin – Physical Review Physics Education Research, 2018
The test of understanding of vectors (TUV) is a multiple-choice test that was recently developed to assess student understanding of vector concepts required in introductory physics courses at the university level. In this study, the TUV was administered to 889 first-year students at the University of Zagreb. The Rasch model was used to evaluate…

Susac, Ana; Bubic, Andreja; Kazotti, Elizabeta; Planinic, Maja; Palmovic, Marijan – Physical Review Physics Education Research, 2018
Previous studies have identified physics students' difficulties with graph slope and area under a graph in different contexts. In this study we compared physics and nonphysics (psychology) students' understanding of graphs; i.e., we evaluated the effects of concept (graph slope vs area under graph), type of question (qualitative vs quantitative),…

Jelicic, Katarina; Planinic, Maja; Planinsic, Gorazd – Physical Review Physics Education Research, 2017
Electromagnetic induction is an important, yet complex, physics topic that is a part of Croatian high school curriculum. Nine Croatian high school students of different abilities in physics were interviewed using six demonstration experiments from electromagnetism (three of them concerned the topic of electromagnetic induction). Students were…

Susac, Ana; Bubic, Andreja; Martinjak, Petra; Planinic, Maja; Palmovic, Marijan – Physical Review Physics Education Research, 2017
Developing a better understanding of the measurement process and measurement uncertainty is one of the main goals of university physics laboratory courses. This study investigated the influence of graphical representation of data on student understanding and interpreting of measurement results. A sample of 101 undergraduate students (48 first year…

Ivanjek, Lana; Susac, Ana; Planinic, Maja; Andrasevic, Aneta; Milin-Sipus, Zeljka – Physical Review Physics Education Research, 2016
This study investigates university students' graph interpretation strategies and difficulties in mathematics, physics (kinematics), and contexts other than physics. Eight sets of parallel (isomorphic) mathematics, physics, and other context questions about graphs, which were developed by us, were administered to 385 first-year students at the…

Erceg, Nataša; Aviani, Ivica; Mešic, Vanes; Gluncic, Matko; Žauhar, Gordana – Physical Review Physics Education Research, 2016
In this study, we investigated students' understanding of concepts related to the microscopic model of gas. We thoroughly reviewed the relevant literature and conducted think alouds with students by asking them to answer open-ended questions about the kinetic molecular theory of gases. Thereafter, we transformed the open-ended questions into…

Aviani, Ivica; Erceg, Nataša; Mešic, Vanes – Physical Review Special Topics - Physics Education Research, 2015
In this study we investigated how two different approaches to drawing free body diagrams influence the development of students' understanding of Newton's laws, including their ability to identify real forces. For this purpose we developed a 12-item two-tier multiple choice survey and conducted a quasiexperiment. This experiment included two groups…

Planinic, Maja; Ivanjek, Lana; Susac, Ana; Milin-Sipus, Zeljka – Physical Review Special Topics - Physics Education Research, 2013
This study investigates university students' understanding of graphs in three different domains: mathematics, physics (kinematics), and contexts other than physics. Eight sets of parallel mathematics, physics, and other context questions about graphs were developed. A test consisting of these eight sets of questions (24 questions in all) was…

Planinic, Maja; Ivanjek, Lana; Susac, Ana – Physical Review Special Topics - Physics Education Research, 2010
The Force Concept Inventory (FCI) is an important diagnostic instrument which is widely used in the field of physics education research. It is therefore very important to evaluate and monitor its functioning using different tools for statistical analysis. One of such tools is the stochastic Rasch model, which enables construction of linear…
