This workbook presents lessons, workshop sessions, and laboratory exercises designed to help youth and adults clarify personal values and develop decision-making skills. The workbook (or "portable school") provides guidance in procedure and method of values clarification. The learning experiences involve users of the text in establishing criteria,…

This publication presents changes and modifications for 2007-2008 to the "International Rules for Precollege Science Research: Guidelines for Science and Engineering Fairs." It is written to guide fair directors, teachers, scientists, parents, and adult volunteers as they pursue their work of encouraging students to explore and investigate their…

According to the spatial registration hypothesis, the representation of stimulus location is automatically encoded during perception and it can interact with a more abstract linguistic representation. We tested this hypothesis in two experiments, using the semantic judgements of words. In the first experiment, words for animals that either fly or…

This study investigates how high school students respond to an environment of authentic science inquiry while participating in an intensive summer institute, the Waksman Student Scholars Programme at Rutgers University. We examined how students apprenticed with expert scientists in a study of contemporary questions in molecular genetics. Students…

This study examined the influence of critical reading orientation on use of external strategies such as note-taking and underlining while reading an expository text. In two experiments, undergraduate students were asked either to review an article on a linguistic policy (critical reading) or to summarise it (less-critical reading). Experiment 1…

This essay describes the results of an experimental class co-taught by an historian and a social studies educator. The class was designed to accomplish two things: to narrow the gap in disciplinary thinking between preservice teachers and historians, and to overcome the preservice teachers' compartmentalized thinking about the nature of their…

Modeling has been shown to correct weaknesses of traditional instruction by engaging students in the design of physical models to describe, explain, and predict phenomena. Although the modeling method can be used without computers, the use of computers allows students to study problems that are difficult and time consuming, to visualize their…

The author studied children's (aged 5-16 years) and young adults' (aged 18-22 years) perception and use of facial features to discriminate the age of mature adult faces. In Experiment 1, participants rated the age of unaltered and transformed (eyes, nose, eyes and nose, and whole face blurred) adult faces (aged 20-80 years). In Experiment 2,…

In our Fundamentals of Genetics lab, students perform a wide variety of labs to reinforce and extend the topics covered in lecture. I developed an active-learning lab to augment the lecture topic of mutagenesis. In this lab exercise, students determine if a compound they bring from home is a mutagen. Students are required to read extensive…

A three-dimensional pendulum, modelled after the Laser Interferometer Gravitational-Wave Observatory's suspended optics, was constructed to investigate the pendulum's dynamics due to suspension point motion. In particular, we were interested in studying the pendular-pitch energy coupling. Determination of the pendular's Q value (the quality factor…

One aim of physics laboratory instruction is to help students connect theory to practice. So experiments are often chosen in order to "demonstrate" specific concepts. Furthermore, students are expected to approach phenomena in a scientific way, that is, they should develop a hypothesis and plan their experiments accordingly. Although it is usually…

This paper examines the impact of implementing Participatory School Administration, Leadership and Management (PSALM) on the levels of trust among the educational stakeholders in Philippine public secondary schools. After an introductory section, the research context is provided by briefly reviewing relevant literature on PSALM and on trust and by…

With the number of popular medical and forensics programs on television and many references in the media today, even elementary students can comfortably throw around terms such as "cells," "DNA," and "artificial products." However, their questions on these topics often go unanswered, or they are left with misinformation regarding these concepts.…

The location of an object is often described by spatially relating it to a known landmark. The spatial terms used in such descriptions can provide various types of information. For example, projective terms such as "above" indicate direction but not distance, whereas proximal terms such as "near" indicate distance but not direction. Previous…

A new, fast and effective colorimetric analysis of the artificial sweetener aspartame is presented for application in undergraduate laboratory courses. This new method incorporates the use of a modified biuret reagent for selective detection and analysis of aspartame in aqueous solutions. The modified reagent is less caustic than the traditional…
