Fifty adolescents (7th and 10th grades) participated in a ten-session argumentation programme as part of which they produced dialogues and written texts on the topic of whether or not Portugal should receive more refugees. Applying social identity and intergroup threat theories as frameworks, causes for flight and seeking asylum were felt to be…

The aim of this study is to examine the effects of computer-based analogy (CBA) used in science teaching in terms of the unit of Structure and Properties of Matter on seventh-grade students' academic success. The attitudes of students against science teaching lesson were also described in this study. This study was applied to 60 seventh-grade…

We compare poor-performing and normal-performing decoders' processing times on real words, pseudo-homophones, and nonwords (Study 1), and evaluate how a processing time difference is associated with rates of decoding development (Study 2). Over 800 sixth and seventh graders took an online reading component battery, which included a decoding test,…

Since the release of "A Framework for K-12 Science Education" in 2012, there has been a significant shift toward the use of science and engineering practices that mirror the way scientists do their work (NRC 2012). The "Framework" states, "A focus on practices (in the plural) avoids the mistaken impression that there is…

This study aims to identify students' approaches toward courses lectured by visual arts teachers with elements of popular culture with a view to enabling students to attain 7th grade targeted achievements. To this end, the multiple-case design, one of the qualitative research methods, was utilized in the study. The sample of the study comprised 11…

Given the important role played by students' spatial reasoning skills, in this paper we analyse how students use these skills to solve problems involving 2D representations of 3D geometrical shapes. Using data from in total 1357 grades 4 to 9 students, we examine how they visualise shapes in the given diagrams and make use of properties of shapes…

The present study investigated the executive functioning of working memory, inhibition, shifting, and planning in Chinese adolescent readers with dyslexia and how they related to Chinese (L1) and English (L2) reading comprehension. Fifty-seven Hong Kong Chinese students at Grade 7 were compared with 57 typically developing readers of…

This paper reports a study developed with twenty-six students from a 7th-grade class and was carried in the context of teaching experience in the school year of 2016/2017, using an applet, Equation Buster, on the learning of solving single-variable linear equations. The research objectives are to assess how this applet can help students to see the…

The main goal of this research is to study the effect of modelling with system dynamics on learning. Specifically, this research studies if using inductive or deductive learning methods applied during modelling with system dynamics has any effect on problem solving skills of students. This research has three other goals: Firstly, the successful…

Mechanisms are central in scientific explanations. However, developing mechanistic explanations is difficult for students especially in domains in which mechanisms involve abstract components and functions, such as genetics. One of the core components of genetic mechanisms are proteins and their functions. Students struggle to reason about the…

In this study, it was aimed both to examine middle school students' perceptions of the concept of pattern and to reveal if the metaphoric perceptions which the students created in relation to the concept of pattern changed according to the variable of grade level.
