STEM education in elementary school is guided by the understanding that engineering represents the application of science and math concepts to make life better for people. The Engineering Design Process (EDP) guides the application of creative solutions to problems. Helping teachers understand how to apply the EDP to create lessons develops a…

This study begins by connecting semantic elaboration with conceptual understanding and syntactic elaboration with procedural understanding in the context of fractions. Through case studies and discourse analysis, the work and communication of students in fourth through sixth grade is analyzed to determine the extent of their semantic and syntactic…

For new-majority students (traditionally underrepresented minority, first-generation, and low-income students) who are less likely to have access to support systems, learning how to navigate the often hidden facets of academia can be a challenge. Providing programming that helps students learn how to navigate the academic landscape as they…

The through-the-air mode is the "real engine" for thought and communication, and that on which secondary representations such as print or Braille are based. This should not be construed as an either-or; it is important to develop high levels of thought in both through-the- air and the corresponding secondary (or captured) modes. It is…

Background: This study investigates the role of figures of speech in the process of conceptual change in the physics classroom. Purpose: Its objectives are to examine what teachers and students perceive to be the advantages in using figures of speech in teaching physics concepts, what they perceive to be the challenges in using them, and how…

This study conducts a textbook analysis in the frame of the following working hypothesis: The transformation of scientific knowledge into school knowledge is expected to reproduce the problems encountered with the scientific knowledge itself or generate additional problems, which may both induce misconceptions in textbook users. Specifically, we…

Organic chemistry students struggle with understanding the energetics of chemical reactions. Reaction coordinate diagrams are one tool that is widely used in organic chemistry classrooms to assist students with visualizing and explaining the energy changes that take place throughout a reaction. Thirty-six students enrolled in organic chemistry II…

The present study uses the intuitive rules theory as a framework to examine whether some of the difficulties in dealing with errors and uncertainties observed among students in the university physics laboratory can stem from their use of intuitive rules. The study also examines the relationship between the use of intuitive rules and laboratory…

People often think that power only flows downhill in school. The author draws on his own research observations, as well as the philosophy of Michel Foucault, to offer more nuanced insights. He explains that power is not a "thing" people can possess and that it flows in multiple directions, forming a web of influence. These insights…

Instructional strategies that support meaningful student learning of complex chemical topics are an important aspect of improving chemistry education. Adequately assessing the success of these approaches can be supported with the use of aligned instruments with established psychometrics. Here, we report the implementation and assessment of one…

Purpose of this study is to determine cognitive structures, conceptual knowledge and misconceptions of the 8th grade students concerning concepts of citizenship through a word association test. In direction of this purpose, a word association test consisting of democracy, sovereignty, independency, freedom, right and responsibility concepts have…

Background: Many students carry negative beliefs about nuclear radiation and have concerns regarding the safety of nuclear power. However, most of these students have not had any personal or educational experiences with nuclear radiation or reactors on which to form these opinions. Purpose: To examine the influence that a visit to a nuclear…

Background: Many misconceptions about breast cancer exist. College students have the opportunity to perform breast cancer risk-reducing behaviors. Purpose: The purpose of this study was to assess breast cancer knowledge among university students and examine the influence of breast cancer knowledge on health behaviors for breast cancer prevention.…

This paper reports on the results from administering a modified version of the Introductory Astronomy Questionnaire (IAQ) to middle school students and preservice science teachers in Norway. Ranking tasks formed a key part of the instrument, and we detail a new method for analyzing ranking task data. One of our main findings was that even after…

Developing students' geometric reasoning skills is dependent on the quality of task designs and the role of the teacher. The purpose of this study was to apply Sfard's (2008) interpretive framework to analyse changes in students' mathematical discourse. This paper reports on the results of an investigation into the ways one class of Year 7…
