Limited literature addresses how elementary preservice teachers (PSTs) can advance their thinking about hierarchical geometric relationships. Informed by a commognitive perspective, we investigated this phenomenon as a matter of discursive change, focusing on word use, visual mediators, and narratives. We report on a teaching experiment involving…

We have reified the concept of economy. I review some illustrations of the current use of economy and argue for making the economy our concept. It is too important to leave to economists.

Geography education requires a combination of knowledge, skills, and geospatial relational thinking. To improve the learning efficiency and durability of knowledge, a new inquiry-based instruction system using tangible user interfaces has been developed. The tangible landscape modeling system (TLMS) comprises four components including a malleable…

A new diagnostic instrument, the Conceptual Survey on Wave Optics (CSWO), was developed and validated on 224 high school students (aged 18-19 years) in Croatia. The process of test construction, which included the testing of 61 items on the total of 712 students is presented. The final version of the test consists of 26 multiple-choice items which…

Children's early knowledge and skills set the stage for later reading development. The present studies examined children's conceptual knowledge of reading prior to formal literacy instruction. Young children's knowledge about who is able to read books and what readers are reading when they read books has been studied primarily through interviews.…

Quantum mechanics (QM) has become part of many secondary school curricula. These curricula often do not include the mathematical tools for a formal, mathematical introduction of QM. QM therefore needs to be taught at a more conceptual level, but making secondary school students understand counterintuitive QM concepts without introducing…

Research-based assessments (RBAs) measure how well a course achieves discipline-specific outcomes. Educators can use outcomes from RBAs to guide instructional choices and to request resources to implement and sustain instructional transformations. One challenge for using RBAs, however, is a lack of comparative data, particularly given the skew in…

This study examined students' views on geometry teaching via three-dimensional dynamic geometry software Cabri 3D. Teaching designed with Cabri 3D for solids volume measurement was implemented for 16 students in the eighth grade from a public secondary school in Turkey. The data obtained from the interviews with the students about the teaching,…

This study aimed at determining the category and analyzes the mental models of the students from three senior high school clusters (low, medium, high) on the solubility and solubility product topic, knowing students' opinions on chemistry subject, knowing learning methods and assessment that teacher used in solubility and solubility products…

Physical and life science disciplines emphasize how basic structural units influence function, yet it is challenging for students to understand structure-function relationships, particularly at molecular scales. Undergraduates in our biology capstone course struggled to connect mutations in a gene encoding a key protein in a cell development…

This research examines the effectiveness of the STEM Supported Inquiry-Based Learning Approach on the conceptual understanding of 7th graders. In the study, a mixed-method design was adopted. The research was carried out with 64 students studying in a secondary school. The study used a Conceptual Understanding Test (CUT) and an Interview Form as…

The purpose of this study was to find out the influence of the integration sequence of interactive simulation on the construction of the scientific explanation of buffer solutions. This study was conducted with 30 pre-service science teachers. The control group was randomly assigned to study with lecture first and then interactive simulation-based…

This study examined the effects of an Arduino microrobot activity on college students' interest in robotics through three specific objectives: (1) determining how students' conceptual understanding regarding the basics of microcomputing and computer programming changes after engaging in an engineering robotics learning module, (2) assessing the…

Language and numerical development are associated in early childhood. In the present study, we focused on the association of the development of children's cardinality understanding of small numbers and their knowledge on unspecific quantifiers (i.e., many, a few). In a longitudinal study, we pursued the research question whether children's…

The aim of the study is to investigate the level of understanding of light-related concepts of teacher candidates who took the "Basic Science in Primary School" course in the classroom teaching undergraduate program. This research is a descriptive study. The study group consists of 65 teacher candidates, 51 female, and 14 male studying…
