The term 'Plant Blindness' describes people tending to overlook plants, even though they have an enormous importance for life on earth, especially because of their ability to photosynthesise. Many attempts have been made to counteract plant blindness in biology education. However, so far there is no comprehensive tool to assess the degree of plant…

Learning resources are quite important for online learning while resource provision based on algorithms could not address learners' ubiquitous needs well. Moreover, the structure and content of resources are pre-defined which makes the "Structure" and "Content" coupled closely and could not easily adjust when learners' needs…

Artificial photosynthesis is a promising approach to generate commodity chemicals using abundant chemical feedstocks and renewable energy sources. Despite its importance, affordable and effective hands-on classroom activities that demonstrate artificial photosynthesis and teach key concepts, especially for primary school students, are lacking.…

This paper reports on one preservice teacher's use of the Inquiry-Application Instructional Model (I-AIM) to plan and teach an instructional sequence on photosynthesis to 5th-grade students. Analysis of the preservice teacher's planned and enacted instructional sequences and interviews shows that the preservice teacher was successful in leveraging…

This study examines whether and how tapping into students' everyday language in a web-based learning environment can improve all students' science learning in linguistically heterogeneous classrooms. A total of 220 fifth-grade English Language Learners (ELLs) and their non-ELL peers were assigned to either an everyday English approach…

This study examines the impact of "Disaggregate Instruction" on students' science learning. "Disaggregate Instruction" is the idea that science teaching and learning can be separated into conceptual and discursive components. Using randomly assigned experimental and control groups, 49 fifth-grade students received web-based…

This article describes a collaborative effort that included a botany professor, an art teacher, and a science teacher, called,"Plants, Pots, and Paints." This interdisciplinary project was successful in connecting content across disciplines (science to art) and for motivating fourth-and fifth-grade students to create something beautiful both they…

The purpose of this study was to investigate how concept cartoons, together with other diagnostic and scaffolding tools, could be used in formative assessment, to stimulate talk and argumentation among students in small groups, as part of peer-assessment and self-assessment; and to provide diagnostic feedback about students' misconceptions to the…

This study was designed to theoretically articulate and empirically assess the role of computer scaffolds. In this project, several examples of educational software were developed to scaffold the learning of students performing high level cognitive activities. The software used in this study, Artemis, focused on scaffolding the learning of…
