The purpose of this study was to improve the conceptual development of an infant through age-appropriate picture books, as well as potentially reveal the effects of such books for developing concepts in children's literature. Study participants used the changing criterion design from single-case research models that consisted of 1 infant and 3…

This study explores science teachers' questions encouraging students to see and speak about natural phenomena in novel ways. In particular, the teachers' challenging questions that may be instrumental in persuading students to see and talk about everyday events differently were qualitatively examined. The participants were 22 science teachers.…

This cross-sectional study investigated the conceptual understanding of linear relationships for 195 students enrolled in a single school in a large, urban district across five mathematics courses: Grade 7 Math (n = 24), Grade 8 Math (n = 52), Geometry (n = 43), Algebra 1 (n = 31), and Algebra 2 (n = 45). The following questions guided this study:…

The conception of functions, defined as the relationship between magnitudes or sets of ordered pairs, varies among students depending on the contextualization of the concept within the curriculum, notably in school textbooks. This investigation endeavors to scrutinize the approach taken by Indonesian textbooks in introducing the function concept…

The work presented in the following chapters was undertaken with the goal of understanding and improving education in organic chemistry. Initial work, described in Chapters 1 and 2, focuses on students' ability to explain and rationalize the outcomes of organic chemistry reactions. Chapter 1 explores the relationship between assessment emphasis…

We present an approach to the question of the educational relations between chemistry and physics based on the one hand, on an inferentialist account of scientific representation (Suárez M., (2024), "Inference and Representation. A Study in Modelling Science," Chicago and London: The University of Chicago Press). On the other, we have…

Incorporating open-ended real-world tasks enhances students' access to mathematical and real-life knowledge and maximizes learning experiences. This article examines how a secondary mathematics teacher used an open-ended problem on distributing pay raises to teach mathematical concepts and fairness to students. The teacher's actions exemplify…

Mathematical concepts have been a consensus goal for decades, yet there is little consensus on what is meant by the terms "mathematical concept" and "mathematical understanding." This article attempts to discuss these terms in a way that can be of practical use to teachers. Greater clarity on "mathematical concept"…

This study aims to compare the impact of hybrid learning and online learning on students' understanding of concepts at the college level. The type of research used in this study was a quasi-experimental control group design. This research data collection technique was obtained from 100 students who attended civic education lectures. The number of…

This case study investigated the conceptual understanding of the Simple Pendulum topic amongst physics student-teachers using online experiments. A pre-experimental design was utilised, employing a one-group pretest-posttest approach with 20 student-teachers. The research instruments included a highspeed video activity conducted within Online…

This study aims to investigate the effect of the teaching model developed for hot conceptual change on middle school 7th-grade students' understanding of the Nature of Science (NOS) aspects. In this qualitative and exploratory study, activities were carried out with 24 students of two classes in a village school in the South Marmara region using a…

Local wisdom in the use of medicinal plants is still not understood by students' potential. This study aims to develop student worksheets ("LKPD") on biodiversity of medicinal plants of the tidung tribe for class X students at SMA Negeri 3 Nunukan Regency. The research method used is Research and Development (R&D) with the ADDIE…

This design-based research project explored how various design features of AR-based learning environments (ARLE) influence students' mathematics self-efficacy and learning of kinematics. Specifically, five ARLEs with different design features were developed and implemented with 136 seventh-grade students in two rounds. Data were gathered from pre-…

Tanzanian secondary school students have consistently performed poorly in the topic of motion in a straight line, which involves kinematics formulas and graphs. Despite instruction, many struggle to plot and interpret these graphs, largely due to limited conceptual understanding among both learners and teachers. This study examines the conceptual…

This study explores the metaphorical perceptions of gifted students towards basic science concepts. A total of 210 gifted students participated in the study, which utilized a phenomenology design to reveal the metaphors used by students to describe the concepts of 'universe, living thing, matter, light, sound, electricity and environment'. A…
