This paper introduces the LIDO, or the Low-Inference Discourse Observation tool, that captures discourse moves produced by students and teachers in whole-classroom discussions. Coding methods are described, followed by analyses that explore validity of the LIDO through correlations among LIDO-coded discourse moves and between LIDO scores and…

Owing to its recognition as a 21st-century skill, computational thinking (CT) is currently being introduced into school curricula around the world. However, in-service teachers are largely unprepared for this implementation, which, in turn, makes teacher educators (TEds) important stakeholders in preparing prospective teachers to integrate CT into…

Scientific modeling (SM) is a core practice of science and an important component of scientific literacy. Supporting students in developing the competence to construct, use, evaluate, and revise models is hence of particular relevance. While research has shown that spatial visualization (SV), a core component of spatial ability, is correlated with…

The purpose of this study is to investigate the extent to which science process skills are represented in the texts and activities in 3rd, 4th, 5th, 6th, 7th, and 8th-grade science textbooks according to the learning areas of the science curriculum. The document analysis method is adopted in the current study. Course contents and activities in…

The research aim was to examine the effects of a Critique-Driven Inquiry (CDI) intervention on primary and secondary school students' critical thinking and scientific inquiry competency. Twenty-five 4th grade Taiwanese students from a typical primary school were selected to participate in experimental group 1 (EG1), while 28 7th grade students…

The paper presents results from the evaluation of the Teach for Bulgaria (TFB) program, which is part of the Teach for All global network. TFB activities have relevance for a variety of fast-track pathways to the teaching profession. The evaluation is based on a quasi-experimental assessment of teacher performance through student value-added…

Seagrass ecosystems are widespread, valuable, and threatened. We have used this system as a model to teach 3rd-7th grade students about food webs, the interconnectedness of ecosystems, ecosystem services, and the effects of human activity on coastal systems. Our objective was to increase student understanding of seagrass ecosystems and other key…

This study aims to conduct a multidimensional analysis of the 2017 Science Curriculum taking the previous three curricula into account. The document analysis technique, which is a qualitative research method, was used. The Science curricula of 2000, 2005, 2013 and 2017 were analyzed in detail for this purpose. The 2017 Science Curriculum, which is…

So far, not enough effort has been invested in developing reliable, valid, and engaging assessments in school science, especially assessment of interdisciplinary science based on the new Next Generation Science Standards (NGSS). Furthermore, previous tools rely mostly on multiple-choice items and evaluation of student outcome is linked only to…

Literacy learning clubs are highly motivating small-group collaborations that can improve tweens' and teens' academic achievement, support their social-emotional development, and increase their enjoyment of reading and writing. This book explains the research basis for the author's approach and offers practical instructions for implementation in…

Reported are the results of a multiyear study in which reading comprehension and writing were integrated within an in-depth science instructional model (Science IDEAS) in daily 1.5 to 2 h daily lessons on a schoolwide basis in grades 3-4-5. Multilevel (HLM7) achievement findings showed the experimental intervention resulted in significant and…

This paper aims to analyze the science curricula which is being implemented in Turkey with respect to spiral curriculum approach. To carry out this analyze 3th, 4th, 5th, 6th, 7th and 8th grade education programs are analyzed correlatively based on qualitative research method. The research findings were analyzed in terms of iterative revisiting of…

States of matter are structures that we may easily encounter in the universe as well as our close environment. The plasma state is the fourth state of matter, and it has much different properties in comparison to the solid, liquid and gas states of matter. In order to understand the universe and the environment we live in better, one needs to have…

We present results of an experimental study of an urban, museum-based science teacher PD programme. A total of 125 teachers and 1676 of their students in grades 4-8 were tested at the beginning and end of the school year in which the PD programme took place. Teachers and students were assessed on subject content knowledge and attitudes towards…

Thermal cameras offer real-time visual access to otherwise invisible thermal phenomena, which are conceptually demanding for learners during traditional teaching. We present three studies of students' conduction of laboratory activities that employ thermal cameras to teach challenging thermal concepts in grades 4, 7 and 10-12. Visualization of…
