Students are introduced to the term wavelength in optics at school level. In this paper, we present an inexpensive and simple method to measure the wavelength of the light of a light emitting diode using a light depending resistor. This experimental set-up is developed at Science Laboratory, Nehru Planetarium (Mumbai), India. It is useful as an…

The present study aims to investigate university students' conceptions of liquids with the help of the scientific story writing technique, which is one of the alternative assessment techniques. The study group comprised students studying science (n=50) and biology teaching departments (n=20) in Turkey. Thus, the study carries within two groups. In…

A central goal of introductory physics for the life sciences (IPLS) is to prepare students to use physics to model and analyze biological situations, a skill of increasing importance for their future studies and careers. Here we report our findings on life science students' ability to carry out a sophisticated biological modeling task at the end…

The "Primary SPACE Project Research Report: Sound" (Watt and Russell, 1990) provides interesting reading relating to primary-aged children's concepts of sound. It reveals a range of children's views on how sound is made, how sounds are heard and how sound travels. While some children are shown to have knowledge that sounds travel and are…

This paper presents improvements made to a computerized adaptive testing (CAT)-based version of the FCI (FCI-CAT) in regards to test security and test efficiency. First, we will discuss measures to enhance test security by controlling for item overexposure, decreasing the risk that respondents may (i) memorize the content of a pretest for use on…

In this article, the author describes an activity using physical models -- each a clear plastic box enclosing a miniature coastal town, complete with real water in the "ocean." This activity shows students a natural cause-and-effect relationship that is scientifically simple, yet even many adults don't grasp the worldwide implications:…

Research Findings: This research aims to examine the affordances for high quality instructional support offered by the Northern Territory Preschool Science Games, alongside differences between classroom quality during the enactment of this teaching resource and the broader early childhood program. Applying a multiple-case study approach, quality…

The topic 'photosynthesis' contains many intangible and abstract scientific concepts, regarding which students hold many preconceptions. Conceptual learning is a process of co-creation and flow that requires the teachers' higher educational level on conceptual teaching. The present research considers photosynthesis as an example. Results of Ball's…

The pendulum was an important scientific instrument in the 17th century. It became a typical textbook problem in the 18th century. After the introduction of vectors in physics in the 1890s, the pendulum problem started to be progressively solved in the manner we know nowadays from introductory mechanics courses. Starting from "F = ma"…

The real-time graphing of simple harmonic motion of mass on springs with an Arduino based on an experiment set for teaching and learning physics in high schools where students can learn from real experiences. The objectives of this study are to create and develop a real-time measurement for vertical oscillations of mass on springs using the…

We investigate students' misconceptions in electrostatics, direct current (DC) and magnetism which are important in electricity and magnetism. We developed and administered a multiple-choice questionnaire test to reveal students' misconceptions related to charged bodies, lightning, electric fields, electric potential, forces, DC resistive electric…

Students possess alternative conceptions of many science topics, and these conceptions can act as obstacles for learning scientific concepts. In the field of biology education, students' alternative conceptions of evolution have been widely investigated. However, there is little research on how teachers diagnose and deal with these alternative…

Numerous studies illustrate the value of simulations or project-based learning approaches to enhance the learning of science. Simulations can help students connect across macroscopic, microscopic, and symbolic representations of scientific phenomena, while project-based learning can provide a meaningful narrative and activities for students to…

This study examined how students' position on social-scientific issues (SSIs) influenced their performance on attitude toward science, science conceptual and argumentation learning. It defined two positions adopted by students regarding SSIs: affirmative and oppositional. The interactions between student position and two learning environments --…

Cross-age studies have suggested that although children's notions of scientific phenomena change moderately with increasing age, certain misconceptions persist from preschool to a higher educational level. The purpose of this study was to diagnose the prevalence of selected misconceptions about the particulate nature of matter among preservice…
