This article focuses on an approach to the concept of historical time in early childhood education through the lens of cognitive psychology. It consists of three parts: (1) theoretical approaches, inspired by three broad scientific fields -- cognitive psychology, pedagogy and history; (2) the presentation of educational examples, formed by…

This experimental field study (pre-post-follow-up design) with 184 student teachers examined the effectiveness of an intervention to reduce misconceptions about psychology within an introductory psychology course. For this purpose, over the course's one-semester duration, all students attended six lectures and, in addition, worked individually on…

In this article, we present kindergarten children's ideas about thermal phenomena before any educational intervention took place. In order to capture and account for the heterogeneity of the kindergarten group in this study, first teachers observed children's exploration behavior, task orientation, science interest, and language comprehension in…

This study investigated factors influencing Force and Motion Conceptual Evaluation (FMCE) pretest and post-test scores for a sample (N=1116 students) collected in the introductory calculus-based mechanics class at a large eastern land-grant university. Several academic and noncognitive factors were examined using correlation analysis and linear…

Professional identity development of students is an often discussed but never resolved issue in higher education. To facilitate a shift toward developing students' professional identity, we propose a pedagogical model where students are tasked with developing and providing instruction to their classmates during a 75-minute teaching session.…

Relational thinking and dealing with variables are two essential aspects of algebraic thinking. Relational thinking means viewing mathematical expressions and equations as a whole rather than as individual computing processes. It is characterized by using relationships between mathematical objects, and refers to the relations of equality and…

Empirical research shows that adults' role in play with infant-toddlers is to provide children with play materials, observe from a distance, and control the surrounding dangers. An international trend to increase children's cognitive skills at a very early age has established a need to better understand toddler's conceptual learning and how this…

This qualitative study aimed to explore six student teachers' changing perceptions and understandings of teacher leadership during their participation in a practicum experience in Qatar. The practicum experience particularly targeted developing student teachers' understanding of teacher leadership through discussions, coaching, and mentoring. Data…

This study aims to determine students' difficulties in understanding the concept of polygons in elementary schools. This research is qualitative research with a case study method. The subjects of this study were 30 grade 5 elementary school students from two different schools in the city of Bandung. The instruments used are test and non-test. The…

One of the central tenets of Universal Design for Learning (UDL) is the presentation of concepts using multiple modalities. As new technologies develop, the variety of available representations increases as well. In this paper, we explore how 3D-printed models can provide another avenue of approach to physics concepts. Students with low vision may…

This quasi-experimental design study aimed to examine how exposure to supporting productive struggle teaching practice impacts students' conceptual understanding, procedural fluency, and strategic competence when solving high-demanding quadratic functions problem solving tasks. Results suggested that students in the supporting productive struggle…

In mathematics, learners often spontaneously draw on prior knowledge when learning new ideas. In this study, we examined whether the specific diagrams used to represent more familiar (i.e., whole number division) and less familiar ideas (i.e., fraction division) shape successful transfer. Undergraduates (N = 177) were randomly assigned to…

A student experiment that uses QuEChERS (quick, easy, cheap, effective, rugged, and safe) methodology for extraction and HPLC for quantitative determination of tocopherols from seeds and nuts is described here. Chromatographic separation is achieved by using a pentafluorophenyl stationary phase which gives enhanced separation of the tocopherols…

Organic chemistry students often struggle with reaction mechanisms, particularly in how they are proposed and justified. In this activity targeting second year organic undergraduates, students used infrared spectroscopy (IR) to track the reaction progress of two distinct aldol reactions and used polarimetry to analyze the stereoselectivity of…

In this paper, we explore the early indicators of design fixation occurring during the concept development stage of children's design processes. This type of fixation, which we named: "concept fixation," causes a blind adherence to the current (possibly unfavourable) state of a design idea. Its occurrence hampers the creative thinking…
