The purpose of this work is to examine the issue of pre-service science teachers' (PSST) Geogebra applications on misconceptions about projectile motion (PM) and the permanence of learning concepts. In this study, quantitative research method was used as scientific research method, and semi-experimental design with pre-test, post-test control…

The purposes of this study were to determine metaphoric perception of preservice teachers from different fields regarding technological change and to examine the differences and similarities between perceptions of preservice teachers (1st and 4th grades). This study employed single case (holistic) study as a qualitative approach. Participants…

Resonance is a fundamental concept that is necessary for students' successful learning in organic chemistry. However, there is a need to know more about both (1) what students find important when describing resonance and (2) students' conceptual understanding. This research seeks to address this discrepancy by examining second-semester organic…

The study aims to investigate students' conceptualisation of the quantum numbers concept through their verbal descriptions and pictorial representations of the corresponding atomic structures. The study was conducted with the participation of 192 12th-grade students from six secondary schools in Northern Greece, via a paper-and-pencil test,…

Proof generally has a bad reputation among students, especially at the high school level. In fact, when the first author initially mentioned to her students that she would like to interview them about proof, many reacted with fear. Further, classroom experiences and existing research (Stylianou, Blanton, and Rotou 2015) suggest that undergraduate…

The identification of coloring substances is a relevant task in the field of conservation and restoration, but it can be challenging as in real samples the target analytes are inserted in a very complex matrix made of binders and additives. Understanding this concept is fundamental for upper-division undergraduate students interested in…

The use of three-dimensional printing in chemistry education has expanded greatly in the past 10 years. The technique has been used to demonstrate a range of concepts including molecular structure, orbitals, and point groups; to produce chemical equipment such as cuvettes and columns; and even to print out mathematical shapes and functions. Here,…

Student feedback from an undergraduate biochemistry lab course suggested the use of visibly traceable proteins may assist learning. Based on this feedback, we used guided inquiry lab exercises where students developed and characterized a suite of fluorescent protein-dihydrofolate reductase (DHFR) fusions as tools for a biochemistry teaching lab.…

This article explains how explorations into the quadratic formula can offer students opportunities to learn about the structure of algebraic expressions. In this article, the author leverages the graphical interpretation of the quadratic formula and describes an activity in which students derive the quadratic formula by quantifying the symmetry of…

To support the development of more robust conceptual knowledge, it is crucial to understand the alternative conceptions that students bring to the classroom, and how these can be considered and dealt with through instruction. In this study, we report the alternative conceptions of 498 students enrolled in secondary education in Ireland. A…

This research was performed to determine the Common Metaphorical Perceptions of Prospective Teachers on DNA-Gene-Chromosome Concepts, despite classroom levels and university differences. For the baseline group studies, two State Universities, one from the east and the other from the north of Turkey, were selected to be studied in the Fall Semester…

The role theory plays in research work cannot be over-emphasized. A theory that is apt gives direction to research work in explaining, organizing, analyzing, and predicting phenomenon and showing their relationships in order to enhance understanding. Despite these roles played by theory, upcoming scholars and students many at times fail to use…

This paper describes a study that used a novel method to investigate conceptual difficulties with mathematical induction among two groups of undergraduate students: students who had received university-level instruction in formal mathematical induction, and students who had not been exposed to formal mathematical induction at the university level.…

Many students do not have a deep understanding of slope. This paper defines what a deep understanding of slope is in terms of mathematics-education theory. The various factors which help explain why such a deep understanding is difficult to acquire are then discussed. These factors include the following: the different representations for slope;…

Mathematical connections play an important role in achieving mathematical understanding. Therefore, in this article, we report research whose objective was to identify mathematical connections that pre-university students make when they solve problems that involve the derivative and the integral. In this research, we consider a mathematical…
