Building on rich training literature, we examined which skills constituting the control-of-variables strategy (CVS) benefit from a comprehensive training, and which develop similarly during content-focused inquiry at ages 10-12. In addition, we examined whether prior knowledge, reasoning abilities, and reading comprehension explain variation in…

This study aimed to investigate the following questions: Does the use of thinking maps and semantic mapping during explicit vocabulary instruction affect content specific science vocabulary knowledge and comprehension in fourth grade students? and What are student perceptions of using thinking maps and semantic maps to learn new vocabulary? To…

While some students will pursue careers in science, all will engage with multimodal science-based texts. The effective use of language skills is essential to support sense making in science. The purpose of this study was to examine how elementary teachers integrated language within their science instruction, and how their instructional enactments…

This study analyzed the comprehension strategies and visuals in two science textbook series for grades 6, 7, and 8 as means of better understanding a core element of the ecological component of science literacy. The iScience [Biggs et al. in iScience (Grade 6), McGraw-Hill, 2015a, iScience (Grade 7), McGraw-Hill, 2015b, iScience (Grade 7),…

Inquiry-based teaching methods have been found to enhance students' abilities to understand the process of scientific inquiry. The purpose of this study was to determine if middle school students taught through an inquiry-based teaching approach consisting of scientific skill development, scientific knowledge, and scientific reasoning were more…

In this study, the effect of teaching based on the 5E instructional model on students' conceptual learning was investigated. The participants consisted of three inclusion students with mild mental disabilities who were studying in the sixth grade of a secondary school. A lesson plan based on the 5E teaching model was designed, focusing on the…

This study examined the effects of a teacher-led learning-strategy intervention program on fourth-grade students' reported use and perceived effectiveness of rehearsal and comprehension-oriented learning strategies. During 18 program units, teachers taught about learning and various learning strategies, including visualisation, elaboration and…

The study of water as a K-12 science idea often divorces its properties from its deeply politicized history as a resource that has been limited, compromised, and intentionally withheld from nondominant communities. Although a robust body of scholarship has aptly critiqued decontextualized and depoliticized pedagogies and called for critical…

This is a qualitative case study framed by a sociosemiotic theoretical framework to explore science and language instruction with three Emergent Bilinguals (EBs) in sixth grade. The study details the modeling and explanatory processes used by EBs to mediate science learning through evidence-based argumentation. A thematic analysis of students'…

Confusion may benefit learning when it is resolved or partially resolved. Metacognitive strategies (MS) may help learners to resolve confusion when it occurs during learning and problem solving. This study examined the relationship between confusion and MS that students evoked in Betty's Brain, a computer-based learning-by-modelling environment…

Genetics has become increasingly important in everyday life, a fact that is reflected in state and national science education standards. This study examines the relationship between 474 fifth graders' understandings of the core ideas of "inheritance of traits" and "variation of traits". A confirmatory factor analysis,…

Experimentation skills are a central component of scientific thinking, and many studies have investigated whether and when primary-school children develop adequate experimentation strategies. However, the answers to these questions vary substantially depending on the type of task that is used: while discovery tasks, which require children to…

Engaging in science as an argumentative practice can promote students' critical thinking, reflection, and evaluation of evidence. However, many do not approach science in this way. Furthermore, the presumed confrontational nature of argumentation may run against cultural norms particularly during the sensitive time of early adolescence. This paper…

Improving youth science comprehension is critical to youth development, yet this intended outcome is often overlooked in terms of how Extension programs are delivered. The purpose of the study reported in this article was to determine through the assessment of potential student growth whether applying features of a youth science comprehension…

Improving youth science comprehension in the United States is imperative to reverse current trends in student achievement and to meet an expected shortage of scientists in the future. This lag in achievement scores and need for future scientists is a problem. One challenge is to link inquiry-based learning and experiential education with…
