The current study focused on scaffolding programmes, including cognitive and meta-cognitive components, for science problem solving in a computerised learning environment to identify their unique effects on aspects of student motivation. Using expectancy-value theory as a conceptual framework, the current study focused on two motivational aspects:…

This randomised controlled trial used a mixed-methods approach to investigate the frequency and how elementary teachers integrated engineering design (ED) principles into their science instruction following professional development (PD). The ED components of the PD were aligned with Cunningham and Carlsen's [(2014). "Teaching engineering…

This embedded mixed method study used a randomised controlled? trial design to examine two cohorts of upper (grades 4-6) elementary teachers' classroom implementation of nature of science (NOS) instruction following their participation in a statewide professional development (PD). The treatment group (n = 145) was compared to a control group (n =…

The present research tested the hypothesis that the reading of science text can create new misconceptions in students with incongruent prior knowledge, and that these new misconceptions will be similar to the fragmented and synthetic conceptions obtained in prior developmental research. Ninety-nine third- and fifth-grade children read and recalled…

This study used an experimental, pretest-posttest control group design to investigate whether participation in a large-scale inquiry project would improve primary teachers' attitudes towards teaching science and towards conducting inquiry. The inquiry project positively affected several elements of teachers' attitudes. Teachers felt less anxious…

This randomized controlled trial or "true experiment" examines the effects of a school garden intervention on the science knowledge of elementary school children. Schools were randomly assigned to a group that received the garden intervention (n?=?25) or to a waitlist control group that received the garden intervention at the end of the…

The scientific competencies advocated by the Programme for International Student Assessment (PISA) focus on the abilities needed in students' adult lives. This study investigated how such scientific competencies could be improved by using online argumentation. One hundred and thirty-eight 8th grade high school students took part in the study, with…

Our study investigated whether problem-oriented designed ecology lessons with phases of direct instruction and of open experimentation foster the development of cross-domain and domain-specific components of "experimental problem-solving ability" better than conventional lessons in science. We used a paper-and-pencil test to assess…

This paper concerns the identification of teaching strategies that enhance the development of 4th grade students' experimental design skills at a public primary school in Argentina. Students' performance in the design of relevant experiments was evaluated before and after an eight-week intervention compared to a control group, as well as the…

This study investigates the role of the discursive process in the act of scientific knowledge building. Specifically, it links scientific knowledge building to risk perception of Genetically Modified Organisms (GMOs). To this end, this study designed and implemented a three-stage argumentation programme giving pre-service teachers (PSTs) the…

This study examined the effect of learning progression-aligned formal embedded formative assessment on conceptual change and achievement in middle-school science. Fifty-two sixth graders were randomly assigned to either an experimental group or a control group. Both groups were taught about sinking and floating by the same teacher with identical…

Climate change generally and global warming specifically have become a common feature of the daily news. Due to widespread recognition of the adverse consequences of climate change on human lives, concerted societal effort has been taken to address it (e.g. by means of the science curriculum). This study was designed to test the effect that…

The purpose of this study was to examine the impact of mobile learning among young learners. Specifically, we investigated whether the use of mobile devices for data collection during field trips outside the classroom could enhance fourth graders' learning about the parts of the flower and their functions, flower pollinators and the process of…

The purpose of this study is to investigate the effectiveness of guided-inquiry approach in science classes over existing science and technology curriculum in developing content-based science achievement, science process skills, and attitude toward science of grade level 6 students in Turkey. Non-equivalent control group quasi-experimental design…

Considerable research has focused on how best to satisfy modern societies' needs for skilled labour in the field of science. The present study evaluated an intervention programme designed to increase secondary school students' motivation to pursue a science career. Students from 3 schools of the highest educational track participated for up to 2…
