Science centers provide an engaging way for young learners to explore related concepts. The hands-on nature of each exercise secures the stimulation necessary to maintain focused attention. In this article, the authors describe a multi-day 5E (Engage, Explore, Explain, Elaborate, Evaluate) lesson on nocturnal and diurnal animals with science…

Estimation of soil texture is an essential skill for soil scientists, but a difficult skill to learn. We compared two approaches for teaching soil texture: the traditional flowchart approach and an experimental self-calibration method. Three lab sections of an introductory soil science class were assigned to learn by the flowchart method (n = 60)…

This study investigated with the help of in-depth interviews and a think-aloud-approach how 10- to12-year-old children (n = 46) in the Canton of Berne, Switzerland, get to know species, how they identify plants and animals, and for how important they consider species knowledge to be. Own observations and sensual experiences coupled with positive…

We outline the basic theory behind white light interferometry and the workings of a typical light interferometer microscope. We study WLI images obtained for rough and smooth chrome steel spheres to illustrate the principle that curved rough surfaces can be imaged with such a device as long as the surface roughness is kept within certain limits.

In this study, we compared students' learning from two conditions in a unit on inclined planes: Virtual-then-Physical (V-t-P) (n = 50), where students conducted a virtual lab followed by a physical lab, or vice versa in the Physical-then-Virtual condition (P-t-V) (n = 60). We analyzed students' written explanations after each lab focusing on…

Teaching and learning introductory thermodynamics has drawn considerable research attention over the last two decades, especially in several disciplines of higher education. Under particular investigation is the First Law of Thermodynamics (FLT), which offers an expression of energy conservation in thermodynamic systems, as the evidence shows that…

We present a simple and affordable method for making a surface electrodynamic trap for microparticles. The principles of electrodynamic trapping of charged particles are discussed and step-by-step instructions on how to make a surface trap are given. In addition to the electrodynamic trap implementation and operation process, options for its…

Learning science outdoors can enhance the understanding of theoretical scientific content taught in the classroom. However, learners are rarely afforded the opportunity to go outdoors to learn chemistry. This study investigates how problem-based learning outdoors can facilitate the understanding of basic chemistry in teacher education. A teaching…

When teaching a general education introductory astronomy course that includes a mathematics prerequisite, it is important to convey that formulas and equations physically represent properties of actual objects and processes that occur that can actually be observed. Students with varying comfort levels with mathematics often need to be convinced…

In this paper, I ask: 'Can digital games support the learning of scientific inquiry as a situated practice? If so, how?' To approach this question, I draw upon feminist, STS, and pragmatist scholarship to develop a framework that can be used to analyze how a learning environment has been designed to teach scientific inquiry, as well as how it can…

Learning progressions (LPs) serve as frameworks for understanding the level of complexity of students' ideas within a domain. Multifaceted LPs contain multiple interrelated constructs where increased knowledge in one construct may increase knowledge of a separate construct. While it is challenging to identify and test these contingencies between…

This longitudinal case study investigates how one science teachers' conceptions change in one domain (assessment of science learning) but not in another (understanding the pedagogical implications of student diversity) over a period of 10 years that includes a university teacher education program and nine subsequent years of experience of…

The study aimed to investigate the effects of a STEM-based course design on students' attitudes toward STEM and a science course. STEM activities were prepared per learning outcomes relating to the "illumination and sound technologies" learning domain in the Grade 4 science course. The study was carried out based on an experiment and…

It is important for students to understand force concepts because they are central to learning physics and other sciences; however, students find it difficult to understand. There are calls for teachers to tap into their professional knowledge and develop beliefs that help them assist students comprehend the topic. To meet this challenge,…

The study deals with Lithuanian science teachers' self-confidence in teaching science and its role in teachers' innovative activities on the basis TIMSS 2015 data set. The latent construct of science teachers' self-confidence in teaching science was examined using confirmatory factor analysis (CFA). Seeking to disclose the influence of science…
