The Big6 model is a systematic approach to information problem-solving that relies upon critical thinking skills. It is the most used model for information literacy instruction in schools worldwide. Since there is a lack of information literacy skills instruction in the educational system of Iran, especially in primary schools, this research evaluates an information literacy intervention in the Iranian 6 th grade science classroom. The study employs a mixed-method explanatory design using a true experimental method with pre-test and post-tests. The qualitative phase investigated the experiences and perceptions of the experimental group. Results show that integrating the Big6 model into the primary science curriculum helps the students to improve their information literacy skills as well as gain a deeper understanding of the research process. Overall, the research contributes evidence to show the effectiveness of a collaborative teaching approach in information literacy instruction. This approach promotes positive attitudes among students towards the school library and the school librarian's role in the educational process.
Solutions to global issues demand the involvement of scientists, yet concern exists about retention rates in science as students pass through school into University. Young children are curious about science, yet are considered incapable of grappling with abstract and microscopic concepts such as atoms, sub-atomic particles, molecules and DNA. School curricula for primary (elementary) aged children reflect this by their limitation to examining only what phenomena are without providing any explanatory frameworks for how or why they occur. This research challenges the assumption that atomic-molecular theory is too difficult for young children, examining new ways of introducing atomic theory to 9 year olds and seeks to verify their efficacy in producing genuine learning in the participants. Early results in three cases in different schools indicate these novel methods fostered further interest in science, allowed diverse children to engage and learn aspects of atomic theory, and satisfied the children's desire for intellectual challenge. Learning exceeded expectations as demonstrated in the post-interview findings. Learning was also remarkably robust, as demonstrated in two schools eight weeks after the intervention, and in one school, one year after their first exposure to ideas about atoms, elements and molecules.
This chapter challenges existing school science curricula modes for teaching atomic-molecular structure and describes a current research project designed to provide supporting evidence for reviewing school science curricula. Using evidence from this project and other research studies, the chapter argues for the introduction of atomic-molecular structure in the curriculum at Year 3 or 4 and proposes that consideration be given to devising a spiral curriculum in which the macroscopic and microscopic properties of matter are taught concurrently rather than sequentially.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
