Designing Curriculum-Based Mathematics Professional Development for Kindergarten Teachers

This study examines the influence of a year-long mathematics professional development program on Kindergarten teachers’ beliefs, content knowledge, instructional practices, and their students’ achievement. The professional development program is grounded in the theoretical construct of learner-centered professional development and focuses on supporting teachers’ integration of standards-based pedagogies aligned with the Common Core State Standards in Mathematics. Data analysis included examining 15 Kindergarten teachers’ mathematics content knowledge, their beliefs about mathematics, their enactment of student-centered pedagogies, and student achievement on curriculum-based assessments. Findings indicated that teachers adopted more student-centered pedagogies and embraced more student-centered beliefs about mathematics teaching during their time in the project. Further, Kindergarten teachers also demonstrated gains in their mathematical content knowledge, and those content knowledge gains were linked to gains in student achievement.     

Mapping the knowledge structure exhibited by a cohort of students based on their understanding of how a galvanic cell produces energy

This study evaluates the use of an open‐ended question to determine students' knowledge structure on the topic of galvanic cells. The open‐ended question was developed and administered to 163 Grade 10 students who had earlier completed a course on electrochemistry. Students' responses were marked as well as coded on the basis of the fields identified from their responses. This was then evaluated statistically to determine the collective knowledge structure of the sample of students. The knowledge structure thus mapped contains both canonical concepts and alternative conceptions (ACs). An important finding emerging from this study is that instructors need to focus student's attention on the dynamic processes involving electrons and ions during the operation of galvanic cells. In order for students to fully understand how a galvanic cell operates, they need to see the whole picture. There are three critical components that lead to students' understanding of how an oxidation–reduction reaction can generate energy and how a circuit is complete: transfer of electrons during oxidation–reduction half‐reactions, flow of electrons within metals, and migration of ions in solution. Also, we found that it is possible for students to use correct chemistry concepts in an incorrect way by establishing linkages among these in an inappropriate manner. We reiterate that apart from evaluating students' ACs, it is also important to evaluate the links between the concepts and conceptions present in students' knowledge structure so that teaching can be made more effective.     

Children's attitudes toward their peers with Down Syndrome in schools in rural Ireland: an exploratory study

Increasingly, children with Down Syndrome are attending mainstream schools, but evidence suggests that these children are more prone to peer rejection and other problems when compared with their non‐disabled counterparts. However, relatively little is known about children's attitudes toward their peers with moderate to serious learning disabilities, including Down Syndrome. This study assessed the attitudes of non‐disabled primary school children (n = 118) in mainstream education toward their peers with Down Syndrome. A secondary aim was to assess whether exposure to audiovisual material promoting inclusion had any immediate effects on overall attitudes. A cross‐sectional, questionnaire‐based survey was administered in four rural‐based schools. The results showed that female participants over 10 were the most sociable. Overall attitudes toward inclusion were consistently and statistically significantly more negative than those toward sociability. Other factors, such as contact with peers with Down Syndrome, were not related to attitudes. Neither was there any change in overall attitudes following exposure to the promotional material. Further work is needed to identify factors underpinning the attitudes of non‐disabled children to their peers with Down Syndrome and how best to promote inclusion in mainstream schools.     

Theoretical Value Belief, Cognitive Ability, and Personality as Predictors of Student Performance in Object-Oriented Programming Environments

The research described in this article reports the results of a study designed to evaluate the relationship among object‐oriented (OO) computer programming task performance and a student's (1) theoretical value belief, (2) cognitive ability, and (3) personality. The results of this study do not support the assertion that cognitive ability is a main determinant of performance. Rather, the findings suggest that characteristics of an individual nature have more effect on a student's performance. This supports our belief advanced herein that theoretical value belief and personality are significant predictors of computer programming performance in OO environments. From the findings of this study, we assert that academicians who must teach OO computer programming consider these factors when developing course materials or student assistance programs.     

America's Wasted Talent: A Karplus Lecture

Millions of young people who could achieve in mathematics and science are being discouraged or prevented from studying these subjects. Access to jobs, status and power in a high-tech, information economy depends upon mastery of these fields, but erroneous beliefs about aptitude are limiting the options for young women, students of color and students from poverty. Curriculum reform efforts are exciting, much-needed improvements, but the single most important change we need is a national consciousness raising. We should hold high expectations for all students and expect virtually all of them to achieve. Outdated and false notions about which groups possess the aptitude for technical subjects should not be used as barriers to access.     

Examining Online Instruction in Undergraduate Nursing Education

Web-based courses have increased in number as one of the primary modes of distance education in undergraduate nursing programs across the United States. An online survey of 171 nursing faculty in the United States with experience teaching Web-based courses served as the primary data source. Interviews and a review of course Web sites provided additional comparative information. Results of this study indicated online faculty spent significantly more time in planning and implementing a Web course than they did a traditional course. Despite this time commitment respondents perceived the teaching experience to be a successful and effective form of instruction that they felt could be used to deliver any type of nursing course. The online teaching experience was described as both collaborative and highly interactive. Most respondents indicated they preferred online teaching to traditional face-to-face instruction. This positive reaction to teaching online supports the future viability of Web-based instruction at colleges of nursing.
