Time estimations, patterns and measurement sense are important skills to develop within the mathematics classroom (Mildenhall, 2016; Thomas et al., 2017). To develop a true understanding of time, students need to holistically understand: the language of time, the notion of duration and succession, how time is measured, and the concept of time…

Spatial skills, which represent the ability to mentally manipulate objects (Schneider & McGrew, 2012; Atit et al., 2020) have been shown to be correlated with entrance, persistence and success in STEM (Shea et al., 2001; Wai et al., 2009). Specifically, these skills have been shown to be necessary to geologists and geoscientists (Hegarty,…

This study investigated Chinese international students' sense of belonging by exploring the cultural and cognitive validity of a commonly used sense of belonging instrument, namely the Hoffman et al.'s (2002) Sense of Belonging Scale. Cognitive interviewing procedures supplemented with open-ended questions were administered to 20 sophomore- and…

The objective of this research was to determine if and to what extent students' learning of geographic concepts can be improved through incorporation of hands-on play with Play-Doh® and LEGO® and geospatial technologies, specifically drones. The project team conducted six months of biweekly, collaborative instruction at Comstock Middle School in…

Mental illness is an epidemic sweeping the nation and, more specifically, the world of education (Salerno, 2016). According to the Center for Disease Control and Prevention [CDC] (2020b), approximately 4.4 million children 3-17 years old in the United States have been diagnosed with anxiety, and approximately 1.9 million diagnosed with depression.…

Assessing students' conceptions related to independence of events and determining probabilities from a sample space has been the focus of research in probability education for over 40 years. While we know a lot from past studies about predictable ways students may reason with well-known tasks, developing a diagnostic assessment that can be used by…

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…
