The paper describes guidelines for the planning, organization, and implementation of virtual activities within a metaverse environment, aiming to familiarize students with key concepts related to hard and soft acids and bases (HSAB) theory. The guidelines are based on experience gained during an online lesson given in January of 2022 for 188…

Grounded within literature pointing to the value of narrative in communicating scientific information, the purpose of this study was to examine the use of stories as a tool for teaching about natural selection in the context of school science. The study utilizes a mixed method, case study approach which focuses on the design, implementation, and…

In this paper we put forward a proposal for the design and evaluation of teaching and learning sequences in upper secondary school and university. We will connect our proposal with relevant contributions on the design of teaching sequences, ground it on the design-based research methodology, and discuss how teaching and learning sequences designed…

Though school is out for the summer, ninth- and tenth-grade students at Union Intermediate High School are burning off energy playing a game of tag on the soccer field. But that is not all they are doing. They are also synthesizing and applying key chemistry concepts they have just learned related to the conditions of the early solar system. They…

An instructional program using four simulation applets was used to facilitate understanding of gas and liquid pressure concepts among twenty-two students in a Year 9 class from an independent secondary school in Singapore. A comparison group consisting of twenty-two students was taught using traditional didactic, chalk-and-talk instruction.…

The integration of student research into a general chemistry laboratory and an environmental geology course has been evaluated for its effectiveness to improve (i) student attitudes about science and chemistry, (ii) student understanding of the nature of experimental science and the scientific method, and (iii) student perceptions of the…

Presents an informal evaluation of the Science as a Way of Knowing Project started in 1983. (PR)

The purpose of this study is to compare the efficacy of three different approaches to professional development in Earth science education: preparing teachers to "adopt" expert-"design" curricula; preparing teachers to use a principled approach to design curricula; and preparing teachers to use a principled approach to "adapt" curricula. The claims…

This study evaluated the effectiveness of the use of videodisc technology in a school system. The videodisc "Understanding Chemistry and Energy" (Systems Impact, 1987) having 20 lessons was used in Physical Science classes (grade 9) and Biology classes (grades 10 and 11) in an experimental school. It was designed to be used with a variety of…

Presents an evaluation of a correlational reasoning module using content from a variety of topics implemented in 12 grade 9/10 classrooms. Among the findings are that performance on a multivariate correlational task increased substantially and the average treatment student scored higher than 99% of those in the control condition. (PR)

The Test of Logical Thinking in Science and tape recordings and notes from a scientific inquiry lesson were used to evaluate the relative effectiveness of the regular and new science programs in developing scientific thinking among elementary school pupils. The findings, limited by sample size and short-term experimental design, indicated that the…

Describes the teacher's guide made up of 125 student activities encompassing 1 year of high school physics instruction called Physics Resources and Instructional Strategies for Motivating Students (PRISMS). The learning cycle of each activity includes three phases: exploration, concept introduction, and concept application. Provides exploration…

Although numerous programs have been developed for Grade Kindergarten through 12 science education, evaluation has been difficult owing to the inherent problems conducting controlled experiments in the typical classroom. Using a rigorous experimental design, we developed and tested a novel program containing a series of pharmacology modules (e.g.,…

The documents enclosed in this report provide a comprehensive and systematic review of the progress made in developing a network organization capable of supporting nanoscience education for the public on a national scale. There is a logic to the studies that were done and to the reports that are included in this notebook. The following are the…

Research has established that students generally possess conceptions relevant to curricular topics before they begin to study them and that these preconceptions often persist despite instruction on scientific theories which contradict them. Discrepancies between students' post instruction conceptions and the scientific theories as taught often…
