This study investigates the ability of future primary school teachers to design experiments when confronted with everyday life problems, particularly those involving complex phenomena or counterintuitive outcomes. Data were collected using a content analysis approach from the written assignments submitted during a Science Education university…

This study aimed to enhance students' experimental skills and laboratory techniques in cell and molecular biology. A trifold intervention involving a Gene Screen Worksheet, a Gene Screen Flowchart, and a laboratory manual were used, along with a mixed methods approach to data collection. The trifold intervention was grounded in constructivism,…

In the present study, atmospheric pressure, an abstract concept that learners generally have difficulty understanding and explaining, was presented to pre-service elementary teachers (PSTs) with the method of argumentation. The argument levels of the PSTs were examined using the Predict-Observe-Explain (POE) experiments in teaching the subject of…

Long before the "Next Generation Science Standards" ("NGSS") were formalized, sensors and other probeware engaged students in science and engineering practices (Metcalf and Tinker 2004). A new generation of probeware based on modern Internet of Things (IoT) technologies is beginning to expand the ways that students can…

The main objective of this paper is to provide an explanation on a conceptual level of how the Mirascope and the occurring image formation work. The physics behind a Mirascope--a well-known device consisting of two concave mirrors--is very complex. In literature, only either high level or very simplified and deficient explanations can be found.…

The results of an earlier four-year longitudinal research study on the development of experimental design skills led to the conclusion that 12-13 year old students probably need more help to design experiments than had been offered to them in that project. This paper reports the findings of the first year of a further four-year empirical research…

In this study, the primary goal was to enhance the knowledge and awareness of 4th-grade primary school students regarding global pandemic diseases and methods of safeguarding against worldwide epidemic diseases which are socio-scientific issues. To achieve this goal, two activity modules tailored for 4th-grade students were created. These…

This study aimed to develop a science experiments guidebook (based on discussion method and enriched worksheet) for fourth grade mainstreamed students with learning disabilities and to investigate its effect on their conceptual understanding of the "Matter and its Nature", "Living Things and Life", "Physical Events"…

The goals of this advanced physics laboratory course emphasized not only to improve students' physics knowledge but also spectrum scientific abilities in particular for preparing their future-ready competencies. One of those scientific abilities was initiated to study that was "the ability to design experiment". It was the fundamental…

In this paper a sequence of nine, easy to manufacture optical black-box experiments with increasing levels of difficulty, and supportive frameworks for physics classes are introduced. They have been evaluated in a lower-secondary school at the end of optics lessons. A black-box is a kind of experimental task where the inner structure is not…

We propose an inquiry-based science activity centred on the effects of climate change on ocean ecosystems. This activity can be used to improve acquisition of knowledge on the effects of climate change and to promote inquiry skills, such as researching, reading and selecting relevant information, identifying a problem, focusing on a research…

The present study employed a quasi-experimental design to assess a computer-based tool, which was intended to scaffold the task of designing experiments when using a virtual lab for the process of experimentation. In particular, we assessed the impact of this tool on primary school students' cognitive processes and inquiry skills before and after…

This article describes the Exploring Experimental Design lesson, which uses a Pictionary-style approach to introduce the elements of the third science and engineering practice: Planning and Carrying Out Investigations, found in "A Framework for K-12 Science Education" (NRC 2012) and the "Next Generation Science Standards"…

As part of "The Blue Marble" project, the Universities of Leicester and Nottingham, UK, have developed day-long, interdisciplinary, hands-on workshops for primary schools to introduce space technology and the role of the research scientist. The workshop activities introduce 5-11 year olds to the role of the UK space industry, show the…

Analyzing evolutionary relationships requires that students have a thorough understanding of evidence and of how scientists use evidence to develop these relationships. In this lesson sequence, students work in groups to process many different lines of evidence of evolutionary relationships between ungulates, then construct a scientific argument…
