This study aims to investigate the effect of the problem-based learning method supported by experiments on the inquiry learning skills of secondary school students and their reflective thinking skills for problem-solving. This research uses a quasi-experimental design with a pretest-posttest control group. This study consists of 21 students in the…

To meet the demands of the Next Generation Science Standards (NGSS), teachers need to reconsider their current instructional practices, shifting from learning about scientific ideas to making sense of phenomena and solving problems using three-dimensional learning components. Project-Based Learning (PBL) provides a framework for creating…

Background: There is substantial descriptive and correlational evidence that the COVID-19 pandemic has exacerbated achievement gaps, as historically underserved students have fallen farther behind in reading. Furthermore, contextual factors like concentrated poverty have systematically amplified the negative effects of the pandemic. Recent data…

The purpose of this study was to conduct a critical text analysis of Next Generation Science Standards (NGSS) policy documents and the resources teachers have access to help them implement these standards into their classroom. NGSS outlines the skills and content needed for students to become proficient in STEM fields. These standards increase the…

[This paper is part of the Focused Collection on Curriculum Development: Theory into Design.] Developing a solid understanding of simple electric circuits represents a major challenge to most students in middle school. In particular, students tend to reason exclusively with current and resistance when analyzing electric circuits as they view…

Life Science is a course that has been taught since the beginning of the first years of Turkish Republic. Life Science curriculum was revised in 1924, 1936, 1948, 1968 and 1998, 2004, 2009, 2015, 2017 and 2018. When the structure of 2018 Life Sciences curriculum is examined, it is seen that the curriculum is composed of general aims, values, basic…

Underrepresentation is endemic across disciplines and across time (National Science Foundation 2019), and extensive research clearly shows that this reflects bias and a lack of access, not a lack of ability in students from those underrepresented groups (National Research Council 2012). Systemic injustice is present in the teaching (Moss-Racusin…

Understanding the nature of science (NOS) has emerged as a core curricular goal since at least the 1960s. While science education reforms around the world have shed light on various epistemic and social underpinnings of science, how science curriculum documents portray the nature of other related disciplines such as mathematics and engineering has…

Although in-depth educational reviews can be carried out building on curricular theories, the appropriation of this knowledge by science education scholarship can still be considered timid. In this paper, our intention is to work on this interface; we first introduce basic concepts from the main curricular frameworks and bring possible…

Campus shutdowns during the SARS-CoV-2 pandemic posed unique challenges to faculty and students engaged in laboratory courses. Formerly hands-on experiments had to be quickly pivoted to emergency remote learning. While some resources existed prior to this period, many currently available online modules and/or simulations focus on a single…

The purpose of this study was to examine the interactions between in-service chemistry teachers' science teaching orientations and other components of their pedagogical content knowledge (PCK). Two experienced chemistry teachers participated in this study. Data were collected through interviews, classroom observations, and field notes as the…

This study investigated the effect of including explicit nature of science (NOS) content in read-alouds of elementary science trade books on the teaching and learning of NOS. We focused on three aspects of NOS: the creative, the empirical, and the inferential NOS. The trade books were read aloud by teachers in three hierarchical levels: Level I…

The United States is currently experiencing its most severe measles outbreak in decades, driven in part by parents' belief that vaccines cause autism. That harmful misinformation is contrary to scientific evidence (DeStefano et al. 2013). The CEO of the American Association for the Advancement of Science, the world's largest multidisciplinary…

The aim of this study is to taxonomically analyse the 9th grade Turkish chemistry curriculum. A descriptive analysis method is used throughout the study. The document analysis is applied as a method to construct the codes and themes to reflect the results of the study. The results of the study exhibit that most of learning outcomes of the 9th…

Large numbers of U.S. students lack proficiency in science, and students from different ethnic and socioeconomic groups show disparities in science achievement.2 Science knowledge and skills are important for both academic and workplace success, and a variety of interventions have been developed to improve student science achievement.…
