This paper re-validates middle school students' learning progression of the concept of buoyancy (Gao et al., 2020) by using two-time point data. The previous study developed a four-level learning progression based on data collected at a single time point using cross-sectional design. This single-time-point model of learning progression calls for a…

Artificial intelligence (AI) is now affecting all aspects of our social lives. Without always knowing it, we interact daily with intelligent systems. They serve us invisibly. At least that is the goal we assign to them: to make our lives better, task by task. Artificial intelligence has the potential to make biology education more engaging,…

One of the core practices of science is constructing scientific explanations. However, numerous studies have shown that constructing scientific explanations poses significant challenges to students. Proper assessment of scientific explanations is costly and time-consuming, and teachers often do not have a clear definition of the educational goals…

Paraprofessionals play a significant role in the education system. However, they often need more training on specific instructional strategies to use with the students they work with. In this study, we trained two paraprofessionals working in a self-contained U.S. elementary classroom for students with high-intensity behavioral support needs. Each…

To develop expertise, novice chemistry students require deliberate practice with immediate and thoughtful feedback. Whereas opportunities for practice are often abundant, opportunities for feedback tend to be much scarcer. To address this challenge, we collaborated with students to develop a flexible and scalable online platform called…

This study examined the effectiveness of instructional design to teach science concepts to visually impaired students. The study was conducted through case study. The study consisted of three stages. The first stage identified the visually impaired students' learning needs related to the concepts of the structure of matter. The second stage…

This study compared the effects of Individualised Instructional Strategy (IIS) and Cooperative Learning Instructional Strategy (CLIS) on male and female senior secondary school students' academic achievement in Organic Chemistry. The study was guided by 2 research questions and 3 null hypotheses. The design was quasi-experimental. The population…

Students learn scientific concepts and mathematical calculations relating to scientific principles by repetition and reinforcement. Teachers and instructors cannot practically spend the long time required during tutorials to patiently teach students the calculations. Usually, teachers assign homework to provide practice to students, hoping that…

Although the "Next Generation Science Standards" and "Common Core State Standards" do not extend to prekindergarten, early learning experiences are vital to preparing young children entering kindergarten with the background knowledge, technical vocabulary, resourcefulness, and dispositions for inquiry that are the foundations…

One of the most powerful strategies to support next generation science instruction is the use of instructional models. The Biological Sciences Curriculum Study 5E (Engage, Explore, Explain, Elaborate, and Evaluate) instructional model is arguably the most widely used version of a learning cycle in today's classrooms. The use of the 5Es as an…

This article is a qualitative study that explored bilingual/ESL science teachers' reflections about subject matter knowledge (SMK) and instructional practice in the elementary grades. Thirty-three teachers were part of a 5-year professional development program designed to enhance instructional quality and effectiveness to teach English learners.…

Positive results of science teaching studies supported with the means provided by technology require the enrichment of the content of blended learning environments to provide more benefits. Within this context, it is thought that preparing a web-assisted model-based teaching, which is frequently used in science teaching, based on the "Matter…

Research indicates that differentiated practices enhance the likelihood of meeting the needs of students who find literacy learning challenging (Tobin & McInnes, 2008; Tomlinson, 2003). The aim of the professional development project described here was to leverage these findings and to build the foundation for future research exploring if…

In an experiment with 65 high-school students, we tested the hypothesis that personalizing learning materials would increase students' learning performance and motivation to study the learning materials. Students studied either a 915-word standard text on the anatomy and functionality of the human eye or a personalized version of the same text in…

Students studying complex science topics can benefit from receiving immediate, personalized guidance. Supporting students to revise their written explanations in science can help students to integrate disparate ideas and develop a coherent, generative account of complex scientific topics. Using natural language processing to analyze student…
