In this study, the research problem was: "Is the computer based physics instruction as effective as laboratory intensive physics instruction with regards to academic success on electric circuits 9th grade students?" For this research of experimental quality the design of pre-test and post-test are applied with an experiment and a control…

Web-based financial commentary, in which experts routinely express market-related thought processes, is proposed as a means for college students to learn vicariously about financial markets. Undergraduate business school students from a regional university were exposed to expert market commentary from a single financial Web site for a 6-week…

In this study, the research problem was: "Is the computer based physics instruction as effective as laboratory intensive physics instruction with regards to academic success on electric circuits 9th grade students?" For this research of experimental quality the design of pre-test and post-test are applied with an experiment and a control…

This study evaluated the efficacy of a preschool mathematics program based on a comprehensive model of developing research-based software and print curricula. Building Blocks, funded by the National Science Foundation, is a curriculum development project focused on creating research-based, technology-enhanced mathematics materials for pre-K…

This paper presents results of Year 2 of an Early Reading First project in a low-income, primarily African American community. Goals of Early Reading First include preparing at-risk preschoolers for school success. This project provided professional development, classroom coaching, books, and materials in support of a literacy-focused preschool…

This study investigated the effects of using Romanized spellings on beginner-level Japanese vocabulary learning. Sixty-one first-semester students at two universities in Arizona were both taught and tested on 40 Japanese content words in a computer-assisted language learning (CALL) program. The primary goal of the study was to examine whether the…

Long-term synaptic enhancement in the hippocampus has been suggested to cause deficits in spatial performance. Synaptic enhancement has been reported after hippocampal kindling that induced repeated electrographic seizures or afterdischarges (ADs) and after long-term potentiation (LTP) defined as synaptic enhancement without ADs. We studied…

The purpose of this study was to explore the effects of conceptual change texts oriented instruction on 9th grade students' understanding of chemical bonding concepts. In this study, the main aim of the preparation of conceptual change texts was to activate students' prior knowledge and misconceptions and to help them to understand the chemical…

Introduction: Many of the residents who supervise medical students in clinical practice are unfamiliar with the principles of effective supervision. Training in teaching skills is therefore seen as an effective strategy to improve the quality of clinical supervision. Method: Twenty seven medical residents were matched and assigned to an…

This paper explores the idea of informal science education in scientific field laboratory (The Science Field Centre). The experimental group of pupils (N = 153) was experienced with approximately 5-day lasting field trips and experiments in the Field Centre in Slovakia. After finishing the course, two different research methods were used to…

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 review focuses on the effects of multiple contacts with respondents on studies of response rates to mail surveys. After screening articles on research criteria, such as the presence of original research and sufficient reporting detail, 28 studies remained of the original 208 identified. The difference in response rate between treatment and…

The effects of conditions of informed consent and disclosure on the performance of 84 students doing a statistics laboratory assignment for an introductory graduate course in statistics at a state university in the southeast were studied. Four separate classes taught by three instructors were included. Subjects ranged in age from 22 to 47 years,…

Problems associated with the analysis of data collected using the Solomon Four Group Design are discussed. The design includes an experimental group and a control group that have been pretested and posttested, and an experimental and a control group that have been posttested only. A sample problem is approached in three different ways. First, the…

THE ACHIEVEMENT OF ALL BEGINNING AND ADVANCED SHORTHAND STUDENTS USING TRADITIONAL SHORTHAND TEACHING DURING 1964-65 WAS COMPARED WITH THAT OF ALL BEGINNING AND ADVANCED SHORTHAND STUDENTS USING THE FOUR-CHANNEL STENOGRAPHIC LABORATORIES AND A LOCALLY DEVELOPED 440-TAPE LIBRARY DURING 1965-66. IN BEGINNING SHORTHAND, 1,596 STUDENTS STARTED AND…
