This study examined pre-service primary teachers' (PPTs) initial NOSI conceptions and their evolution after the immersion in a specific teaching module focused on inquiry and NOSI. The participants were 40 PPTs attending a science education course during a semester. The study consisted of a pre-test/post-test design approach framed qualitative…

The study explored the impact of peer critiquing on preservice teachers' understanding of the nature of science, scientific inquiry, and argumentation in an undergraduate science content course. The aim was to investigate innovative teaching strategies that enhance preservice teachers' comprehension of these key aspects. This study showcased…

The aim of this research was to establish the effects of argumentation and the quality of arguments related to history of the development of organic chemistry: (i) on the level of the pupils' knowledge about the composition, structure and general properties of organic compounds; and (ii) on their perception of the key aspect of NOS that scientific…

This study aimed to develop, implement, and evaluate argumentation-based inquiry teaching practices to train qualified science teachers. In this context, first, practices in argument-based inquiry were developed to have highly qualified individuals with cognitive flexibility; the ability to look at happening from divergent perspectives and…

This study aimed to teach 9th grade students the meanings of scientific theory and scientific law, and the differences between them. The related literature informs that students at different grade levels have misconceptions about the definition of both scientific theory and scientific law and the relationship between them. In this study, the…

There is a gap between the facts learned in a science course and the higher-cognitive skills of analysis and evaluation necessary for students to secure scientific knowledge and scientific habits of mind. Teaching science is not just about how we do science (i.e., focusing on just "accumulating undigested facts and scientific definitions and…

The National Assessment of Educational Progress (NAEP) measures student science achievement nationally, state by state, and, most recently, across selected urban school districts. Periodically, the framework underlying the science assessment is revised or updated. This document, "Science Framework for the 2019 National Assessment of…

In this mixed methods study, the researchers developed a video-based measure called a "Prediction Assessment" to determine preservice elementary teachers' abilities to predict students' scientific reasoning. The instrument is based on teachers' need to develop pedagogical content knowledge for teaching science. Developing a knowledge…

This article presents an instructional strategy called Premise-Reasoning- Outcome (PRO) designed to support students in the construction of scientific explanations. Informed by the philosophy of science and linguistic studies of science, the PRO strategy involves identifying three components of a scientific explanation: (i) premise--an accepted…

Graphing subjects in chemistry has been used to provide alternatives to verbal and algorithmic descriptions of a subject by handing students another way of improving their manipulation of concepts. Teachers should therefore know the level of students' graphing skills. Studies have identified that students have difficulty making connections with…

The molecular basis of evolution is an important and challenging concept for students to understand. In a previous article, we provided some of the scientific background necessary to teach this topic. This article features a series of laboratory activities demonstrating that molecular events can alter the genomes of organisms. These activities are…

Having the learning and retention of science content and skills as a goal of scientific literacy, it is significant to study the issue of retention as it relates to teaching and learning about nature of science (NOS). Then, the purpose of this study was to investigate the development of NOS understandings of students, and the retention of these…

The National Assessment of Educational Progress (NAEP) and its reports are a key measure in informing the nation on how well the goal of scientific literacy for all students is being met. The "Science Framework for the 2015 National Assessment of Educational Progress" sets forth the design of the NAEP Science Assessment. This document is…

Background: Problem-based learning (PBL) is a teaching approach working in cooperation with self-learning and involving research to solve real problems. The first law of thermodynamics states that energy can neither be created nor destroyed, but that energy is conserved. Students had difficulty learning or misconceptions about this law. This study…

This paper describes the development, administration, and results of an instrument to assess changes in students' science abilities as they progress from ninth grade through twelfth grade. Standard science tests commonly in use in schools to measure high school science students' achievement are content specific. Although these tests are useful…
