The purpose of this article is to introduce a 12-step approach for an abbreviated research project to promote research writing in an undergraduate measurement course. This 12-step approach assumes a 14-week semester schedule that is common among many colleges and universities. The steps for the proposed research project include selecting a topic,…

There are many ways to share a collection of data and students' thinking about that data. Explaining the results of science inquiry is important--working scientists and amateurs both contribute information to the body of scientific knowledge. Students can collect data about an activity that is already happening in a classroom (e.g., the qualities…

In the paper the qualitative research in which the researcher has been directly involved, and has himself been examining the research phenomenon in the studied environment, is presented. The aim of this qualitative study is to gather data in the form of rich content-based descriptions of people, events, and situations by using different,…

Most people visit a science center in order to satisfy specific leisure-related needs; needs which may or may not actually include science learning. Falk proposed that an individual's identity-related motivations provide a useful lens through which to understand adult free-choice science learning in leisure settings. Over a 3-year period the…

We have investigated student difficulties with the learning of organic chemistry. Using Perry's Model of Intellectual Development as a framework revealed that organic chemistry students who function as dualistic thinkers struggle with the complexity of the subject matter. Understanding substitution/elimination reactions and multi-step syntheses is…

Objective: Symptoms of overactivity form part of the "DSM-IV" criteria for the combined or hyperactive-impulsive subtypes of attention-deficit/hyperactivity disorder (ADHD); yet little data exist that would quantify the nature of the overactivity component. We aimed to quantify the ability of four different measures of motion sensor data, taken…

In the present study, we have applied a word association procedure for assessing conceptual change in science education, leaning on the presuppositions of the theory of social representations. The proposed method was applied both before and after a university population ecology course. Our results have shown that the teaching procedure can change…

Discusses the domain of measurement and evaluation: methods of data collection, focus of evaluation, criteria for evaluation, and purpose of evaluation. (MLH)

Describes a curriculum evaluation model that includes a focus of evaluation and the method of evaluation. Identifies three distinct modes of evaluation: unstructured subjective observation, semi-structured consensus of opinion, and structured objective observation. Outlines the role played by curriculum evaluation in science education today. (GS)

An approach to evaluation initiated by the Kellogg Foundation called cluster evaluation (not to be confused with cluster sampling) is described. Cluster evaluation provides a skilled, credible evaluator to work with a cluster of projects to assure that useful and defensible information is obtained for program evaluation. (SLD)

Reviews background of atomic absorption spectrometry techniques. Discusses problems encountered and precautions to be taken in determining trace elements in the parts-per-billion concentration range and below. Concentrates on determining chromium in biological samples by graphite furnace atomic absorption. Considers other elements, matrices, and…

Argues that science educators often face the problem of abnormal distributions when conducting large-scale assessments or evaluating national curriculum projects that require complex sampling plans. Examines the precision of science test scores. (DDR)

There has been considerable interest recently in the teaching of skills to undergraduate students. However, existing methods for collating data on how much, where and when students are taught and assessed skills have often been shown to be time-consuming and ineffective. Here, we outline an electronic research skills audit tool that has been…

Indicators of mathematics and science education progress are important to policymakers and the public in order to evaluate the quality of education. Recent reports have evaluated existing indicators and suggested core aspects of mathematics and science education that an indicator system should evaluate. This note discusses two fundamental aspects…

Some steps to identify an initial set of indicators and to develop alternative indicator systems are outlined for educational evaluation and illustrated through the example of a National Science Foundation (NSF) study of mathematics and science education. The first step is to conceptualize potential indicators to specify a comprehensive monitoring…
