Inquiry-based learning can be an effective approach when students are provided with sufficient guidance. However, there is an ongoing debate among practitioners about the nature, type, and level of such guidance. This study investigated the effects on middle school students' (N = 116) conceptual knowledge and inquiry skills acquisition of…

The demand for improving student interest in science has increased efforts toward teaching Einstein's theory of general relativity in schools. Research has already shown that teaching Einsteinian gravity at the secondary level is feasible, however, appropriate resources must be readily available for science teachers to make Einsteinian gravity…

This study investigates the effectiveness of using a REACT strategy instruction enriched with guided inquiry-based experiments to improve 7th-grade students' understanding of mixtures compared to conventional teacher-centered instruction. A convergent parallel mixed-method design was used, and 39 middle school students were divided into…

Although hands-on laboratory experiments are traditionally used in schools, virtual laboratories have entered today's classrooms, due to their specific affordances. In this study, we compared the effect of using hands-on and virtual laboratories in isolation to two different combinations on middle school (7th grade) students' acquisition of…

The aim of this study is to investigate the impacts of nature education on the affective tendencies and science curiosities of students. In this study, one group pretest-posttest test design was used. The study group consists of 30 seventh grade students studying in Istanbul, Turkey. In the study, nature education implementations were carried out…

Despite the inherent potential of cooperative learning, there has been very little research into its effectiveness in middle school laboratory classes. This study focuses on an empirical comparison between cooperative learning and individual learning in the school science laboratory, evaluating the quality of learning and the students' attitudes.…

Experimentation is a valuable way to build understanding in science. EcoXPT research looks at supporting authentic experiment-based inquiry within an immersive virtual ecosystem. EcoXPT includes a variety of investigative tools, including a Mesocosm tool that allows students to set up experimental pools to test interactions between variables. This…

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:…

One obstacle to understanding abstract concepts such as the "control of variables" strategy (CVS) is the tendency for learners to focus on surface rather than deep features in instructional materials. However, in tasks such as learning CVS, these same surface features may also support understanding, provided learners realize the…

For over a century, genetic arguments for the existence of racial inequality have been used to oppose policies that promote social equality. And, over that same time period, American biology textbooks have repeatedly discussed genetic differences between races. This experiment tests whether racial terminology in the biology curriculum causes…

This paper contributes to the discourse in stochastic education of how young students deal with learning settings that allow a data-based approach to probability. By using the micro-structure of arguments by Toulmin (1958), it explores which arguments students use and which role they play in the learning process. The data stems from design…

The so-called control-of-variables strategy (CVS) incorporates the important scientific reasoning skills of designing controlled experiments and interpreting experimental outcomes. As CVS is a prominent component of science standards appropriate assessment instruments are required to measure these scientific reasoning skills and to evaluate the…

The objective of this research and development was to develop a curriculum for enhancing grade 7 students' aesthetic sense and substantial art learning. There were 2 phases of the study consisting of: (i) the study of basic information about art aesthetics, including the attributes, approaches, theories, problems, and needs, (ii) the development…

This paper describes the multiple school and school science experiences of eight Latina students of Central American descent in a tracked, urbanized, middle school setting. Framed by a sociocultural perspective, I describe how eight seventh and eighth grade Latino girls interacted with school science. Implications for the concept "science for…

In this experimental study, 151 middle school students explored 3 historical controversies, first reading and discussing primary source documents in groups, then writing arguments on their own. Students were either randomly assigned to an experimental condition, using argumentative schemes and critical questions as guides during discussions, or to…
