This paper investigates whether and how primary school students improve their epistemic understanding about a particular aspect of the nature of inquiry (NOSI), namely, the 'non-linear nature of inquiry' through an explicit-reflective or implicit instruction. The sample consisted of 30 5th grade students, who were randomly divided into two groups:…

Academic achievement in elementary science achievement scores throughout Title One schools in metro-Atlanta could be identified through analphabetism and improper vocabulary instruction to accommodate students' learning styles. Teaching words explicitly entails extensive time and patience when exposing new science vocabulary. However, teaching…

This study compares direct instruction to two constructivist approaches, namely experimentation and problem-based learning, in fifth-grade science learning in Hong Kong. Constructivist instructional approaches, contrary to direct instruction, stress on students' active role in constructing knowledge in learning. Experimentation and problem-based…

There is a long tradition of teaching science through inquiry, with broad agreement about the form it should take. Students should investigate researchable questions; gather and analyse data; and develop and represent evidence-based claims. Authoritative teacher or textbook representations are generally used to guide this learning (Buckley &…

In the present paper, we have examined the impact of explicit linkage between simulated (i.e., virtual) and real (i.e., physical) experimental settings in order to scaffold conceptual understanding, in the case of floating and sinking (F/S) phenomena explanations. This research is part of a research-based curriculum project and has been…

It is important that preservice and in-service teachers use effective supports for English language learners (ELLs) in science classes to enhance learning. ELLs with limited English proficiency may need more supports to address language barriers that affect student learning. Literature circles can be used to enhance understanding of content when…

The aim of the present study was twofold. First, we aimed to replicate the findings of previous studies which had showed a substantial improvement on procedural and epistemological knowledge after direct instruction and their maintenance in time. Second, we aimed to examine the dynamic relationships of the procedural (control of variables…

This study investigated how student participation in an authentic scientific investigation may shape underrepresented students' views of science and support students in learning science. The research centered on the instructional approach used in a fifth-grade classroom to engage English language learning students from Latino backgrounds in a…

Anecdotal accounts from science educators suggest that few teachers are teaching science as inquiry. However, there is little empirical evidence to support this claim. This study aimed to provide evidence-based documentation of the state-of-use of inquiry-based instruction and explicit instruction about nature of science (NOS). We examined the…

This paper presents the findings from a randomized control trial study of reading/literacy-integrated science inquiry intervention after 1 year of implementation and the treatment effect on 5th-grade low-socio-economic African-American and Hispanic students' achievement in science and English reading. A total of 94 treatment students and 194…

The authors investigated whether the amount of instructional guidance affects science learning and self-efficacy. Sixty 9- and 10-year-old children were randomly assigned to one of the following three instructional conditions: (a) guided instruction consisting of examples and student-generated explanations, (b) direct instruction consisting of a…

We explore the immediate and longer term consequences of different types of instruction about a central topic in middle school science: the "Control of Variables Strategy" (CVS). CVS represents the procedural and conceptual basis for designing simple, unconfounded experiments, such that unambiguous causal inferences can be made. CVS…
