Background/purpose: This study aims to evaluate the effect of the application of the PjBL learning model assisted by AR on students' critical thinking skills. The focus of this study is on sixth-grade students with solar system material, designed to explore how the integration of AR technology in PjBL can improve student engagement, conceptual…

Further analysis of the effectiveness of integrating project-based learning (PjBL) in Invertebrate Zoology courses to improve students' science process skills and conceptual understanding needs to be carried out. This research was aimed to analyze the integration of PjBL in the Invertebrate Zoology course on scientific process skills and…

Young children are familiar with astronomical phenomena from everyday life, such as the movement of the celestial bodies or the shift from day to night. The present study examines the extent to which kindergarten students understand abstract concepts related to celestial bodies and processes (such as gravity and time), and whether they change…

Numerous studies illustrate the value of simulations or project-based learning approaches to enhance the learning of science. Simulations can help students connect across macroscopic, microscopic, and symbolic representations of scientific phenomena, while project-based learning can provide a meaningful narrative and activities for students to…

Critical and creative thinking abilities are part of 21st century skills that have not been well utilized. One effort to improve these abilities can be through project-based learning (PjBL). This quantitative study aims to determine the effect of the PjBL model on students' critical thinking and creative thinking abilities on the ecosystem…

The Clemmensen reduction is a common example of a reaction demonstrating the deoxygenation of carbonyl groups, which is a topic that has been widely studied in the field of organic chemistry. The use of trimethylchlorosilane, as a substitute for concentrated hydrochloric acid, allows for the reduction of carbonyl groups. The Clemmensen reduction…

This pilot study utilizes 360° camera and viewer technology in a science content-based EFL class at a Japanese University. Due to a lack of initial knowledge on how to best incorporate this technology into a content driven EFL class, a co-development strategy was devised between the teacher and students to dynamically design a course over…

We investigated the effect of modeling and visualization resources on upper-division, undergraduate and graduate students' performance on an open-ended assessment of their understanding of physical hydrology. The students were enrolled in one of five sections of a physical hydrology course. In two of the sections, students completed homework…

A thematic course called "Climate Change: Chemistry and Controversy" was developed for upper-level non-STEM students. This course used the socioscientific context of climate change to teach chemical principles and the nature of science. Students used principles of agnotology (direct study of misinformation) to debunk climate change…

We present our Lunar Phases Project, an ongoing effort utilizing students' actual observations within a mental model building framework to improve student understanding of the causes and process of the lunar phases. We implement this project with a sample of undergraduate, nonscience major students enrolled in a midsized public university located…

In a contest featuring hands-on projects, college students were required to design a simple crawling worm using planning, self-monitoring and self-evaluation processes to solve contradictive problems. To enhance the efficiency of problem solving, one needs to practice meta-cognition based on an application of related scientific concepts. The…

A nanotechnology module was developed for ninth grade students in the context of teaching chemistry. Two basic concepts in nanotechnology were chosen: (1) size and scale and (2) surface-area-to-volume ratio (SA/V). A wide spectrum of instructional methods (e.g., game-based learning, learning with multimedia, learning with models, project based…

This article reports the phases of design and use of video editing technology as a medium for creatively expressing science content knowledge in an elementary science methods course. Teacher candidates communicated their understanding of standards-based core science concepts through the creation of original digital movies. The movies were assigned…

Describes a seven-week project completed by the author's eighth-grade science students (as they studied "the chemistry of living things") in which they designed an alien and its world using the scientific concepts that they learned in class. Compares class presentations using PowerPoint software to presentations using posterboard. (SR)

The objective of this study was to evaluate grade 9-12 students' motivation while engaged in two different engineering design projects: marble-sorter and bridge designs. The motivation components measured in this study were focused on students' intrinsic (IGO) and extrinsic (EGO) goal orientations, task value (TV), self-efficacy for learning and…
