The "Hands on CERN" education project makes it possible for students and teachers to get close to the forefront of scientific research. The project confronts the students with contemporary physics at its most fundamental level with the help of particle collisions from the DELPHI particle physics experiment at CERN. It now exists in 14 languages…

A study describes an easy procedure based on a negative photoresist process designed for junior high or high school students, which will introduce them to the key terms and concepts of photolithography. The experiment allows students to visualize the fundamental process behind microchip fabrication, observe the rapid prototyping enabled by such a…

From 1992 through 2003 the Chemical Engineering program at Arizona State offered an integrated series of core courses that taught students how conservation and accounting principles can be applied to describe engineering phenomena across disciplines. A brine-water mixing tank experiment was introduced in the third course in the series (ECE 394C:…

Learning in educational settings most often emphasizes declarative and procedural knowledge. Studies of expertise, however, point to other, equally important components of learning, especially improvements produced by experience in the extraction of information: "Perceptual learning." Here we describe research that combines principles of…

Using cultured fibroblast cells, undergraduate students explore cell division and the responses of cultured cells to a variety of environmental changes. The students learn new research techniques and carry out a self-designed experiment. Through this project, students enhance their creative approach to scientific inquiry, learn time-management and…

Recently, a lot of open source e-learning platforms have been offered for free in the Internet. We thus incorporate the intelligent diagnosis and assessment tool into an open software e-learning platform developed for programming language courses, wherein the proposed learning diagnosis assessment tools based on text mining and machine learning…

People can use a variety of different strategies to perform tasks and these strategies all have two characteristics in common. First, they can be evaluated in comparison with either an absolute or a relative standard. Second, they can be used at varying levels of consistency. In the present article, the authors develop a general theory of task…

An activity called "Project Physics, a Classroom Without Walls" was started during the spring of 2003 at the amusement park in Mirabilandia (Italy). Many thousands of students from Italian middle and high schools are today participating in the initiative. Under the guidance of trained tutors, they perform physics experiments on some of…

To enhance the learning outcomes achieved by students, learners undertook a computer-simulated activity based on an acid-base titration prior to a university-level chemistry laboratory activity. Students were categorized with respect to their attitudes toward learning. During the laboratory exercise, questions that students asked their assistant…

This study sought to connect the science activity educational approach to the higher cognitive development of students using a relatively new learning model, the Cultural Historical theory, based upon the work of Vygotsky. The theory advances the concept that children's intellectual development occurs in interactions with an adult or more capable…

The goal of this mini-curriculum is for students to discover what drinking water really is. Five units are designed to be presented as a lecture and to allow 30 to 40 students to perform every procedure, each testing their own tap water sample. Games are provided in each section to reinforce the concepts presented in each unit. Unit 1 introduces…

This book of life science activities introduces a new experimental animal--the WOWBug, "Melittobia digitata"--that is commonly found in nature but has never before been used in the precollege classroom. It includes 20 activities and experiments for grades 5-12, that cover topics from basic orientation to ecological interactions, from physical…

This pilot study explored the characteristics of children's co-inquiry with a mentor and the changes occurring in their questioning with prolonged engagement in mediated inquiry. Six graduate students, who were practicing teachers, acted as mentors to individual students for inquiry into child-selected topics for 10 weeks. Children ranged in age…

This document is the laboratory manual for the Physics 152 course at Purdue University. It includes a laboratory introduction, hardware and software guide, and laboratory report guide. Labs include: (1) "Measurement Uncertainty and Propagation"; (2) "Introduction to Computer Data Acquisition and Relationships between Position,…

This book contains hands-on science laboratory activities for grades 4 through 9 that use discrepant events to challenge students. All of the "puzzlers" are based upon science principles and include directions for building gadgets that explain the "puzzlers." Topics covered include: volume conservation, magnetic phenomena,…
