Phylogenetic trees are important tools for teaching and understanding evolution, yet students struggle to read and interpret them correctly. In this study, we extend a study conducted by Catley and Novick (2008) by investigating depictions of evolutionary trees in US textbooks. We investigated 1197 diagrams from 11 German and 11 United States…

In this article, we present the question of our didactic research on the relative conceptual evolution and transition from high school to university in Morocco. We focused on the difficulties encountered by students in the first year of the Physics Sciences using a questionnaire which aims at evaluating the evolution of the concept of…

The aim of this study was to improve the criterion-related test score interpretation of a text-based assessment of scientific reasoning competencies in higher education by evaluating factors which systematically affect item difficulty. To provide evidence about the specific demands which test items of various difficulty make on pre-service…

Following the trend in science and engineering education generated by the visible impact created by the Force Concept Inventory (FCI), the investigator developed a Physics of Semiconductors Concept Inventory (PSCI). PSCI fills the need of standardized concept tests for undergraduate education in photonics and electrical engineering. The structure…

These proceedings contain papers of the 3rd International Baltic Symposium on Science and Technology Education (BalticSTE2019) held in Šiauliai, Lithuania, June 17-19, 2019. This symposium was organized by the Scientific Methodical Center "Scientia Educologica" in cooperation with the Institute of Education, Šiauliai University. The…

This paper describes and evaluates a new type of multiple-choice test question that is relatively easy to construct and that challenges students' understandings of biological concepts. The questions involve a small narrative of scientific text that students must evaluate for accuracy. These are termed "You are the Teacher" questions because the…

Describes a technique devised to isolate topics of high perceived difficulty in a school biology syllabus. Discusses results obtained from questioning school pupils, teachers, and university students. (Author/CS)

Diagrams are considered to be invaluable teaching and learning tools in biochemistry, because they help learners build mental models of phenomena, which allows for comprehension and integration of scientific concepts. Sometimes, however, students experience difficulties with the interpretation of diagrams, which may have a negative effect on their…

Two key factors affecting the success of non-major science courses are students' perceptions of topic difficulty and interest. An attitudinal survey administered to 300 college students, after completion of a college science course, evaluated their attitudes toward a geology curriculum. Using a Likert type scale students rated their level of…

Despite rising enrollments, college biology education has until recently lagged behind other science disciplines in reforming undergraduate instruction. However, new approaches are emerging, including introductory classes that focus more on concepts, laboratory assignments that are increasingly sophisticated, and more in-depth curricula for…
