Energy is a concept frequently encountered both in daily life and in various disciplines. Despite such a wide range of scope, conceptualizing it might be challenging at times. This study aims to investigate high school students' views on the concept of energy through a set of various paper-and-pencil tests. For this purpose, 654 high school…

Being able to move between different representations levels (macroscopic, submicroscopic, and symbolic) is important to understand a chemical phenomenon meaningfully. The current study investigated how pre-service science teachers moved from symbolic representation to sub-microscopic representation. A total of 205 pre-service science teachers,…

Dealing with students' conceptions is one of the central elements of student-oriented teaching. To be able to organize learning processes efficiently, it is necessary to look at the learners in a differentiated way and to approach their conceptions individually. The first necessary step is the individual diagnosis of each student's conceptions.…

Research on students' understanding of the greenhouse effect and global warming has been focused on identifying and overcoming misconceptions. However, to date, very few studies have looked into the ways in which student conceptions are organised and interrelated from a model-based perspective. In this study, we investigated student-generated…

In this study, adults naïve to organic chemistry drew stereoisomers of molecules and explained their drawings. From these explanations, we identified nine strategies that participants expressed during those explanations. Five of the nine strategies referred to properties of the molecule that were explanatorily "irrelevant" to solving the…

Teachers' subject matter knowledge is a substantive component of the teaching-learning process. For a teacher to be able to transform and integrate into the classroom all the knowledge and experience they have acquired in the course of the professional activity, it is first necessary to acquire a deep and solid knowledge of the matter. The aim of…

We studied the initial conceptions of 73 pre-service primary teachers regarding the concept of ecosystem and examined how their understanding evolved as a result of participation in an inquiry-based learning exercise. The inquiry process involved identifying students' initial conceptions, making them aware of these, comparison of their ideas with…

Students' ability to explain phenomena were compared when they were provided a model versus asked to draw their own model. As part of a pilot test, 1,405 students in the fourth through twelfth grades from across the United States responded to one of three different modeling tasks. Each task presented students with a phenomenon related to energy…

We present a multi-method design for elucidating young, mostly illiterate children's (grades 1 and 2 of Swiss elementary school, ages 6-8) ideas about energy. The design uses semi-structured interviews and video recordings as the main methods of data generation and collection, respectively. A plurality of tasks, including drawing, sorting and a…

Plant nutrition is a complex subject at any educational level therefore, identification of student's ideas regarding this scientific concept is important in order to define the best instructional learning method. In this study, we conduct a cross-age comparison of the conceptual understanding of compulsory students and prospective elementary…

This study aims to find out the effect of activities and practices on concept education to help carry out activities to teach these concepts more effectively and permanently, and determine student preconceptions about the concepts related to the landforms in the 5th-grade social studies curriculum in the learning subdomain called "People,…

Formative assessment is a teaching method that helps to determine the prior knowledge of students, schedule the course plan accordingly, give it the final shape based on the feedback received from students, and encourage conceptual learning. The aim of this study is to introduce the "annotated student drawings" as one of the common…

The present research explores benefits of using young students' drawings in combination with written responses for gathering information about science concepts. Younger students are still very limited in their verbal expression and less biologically literate than older students. The aim was to determine primary school students' conceptions about…

Children from southern and northern Brazil have a basic knowledge of plants, which they observe during their everyday life. Children ages between 3 to 10 years old (kindergarten & primary school), but the majority of them in the age group of 4-5 (total 145) were asked to draw what they think is a plant (total sample = 332). Afterwards, a equal…

Student-generated annotated concept sketches provide an alternative approach for instructors to formatively assess students' understanding of environmental topics, such as photochemical smog and ozone layer depletion. The sketches are external representations of students' cognitive models. Results obtained from a group of 150 female students using…
