An Innovative Course Featuring Action Research Integrated with Unifying Science Themes

In this article, we describe an innovative capstone course for preservice K-8 teachers integrating action research and a unifying theme in science (AAAS in Science for all Americans. Oxford University Press, New York, 1989; NRC in National science education standards. National Academy Press, Washington, DC, 1996). The goals of the capstone course are to increase student knowledge of the unifying theme, improve written communication skills, and introduce students to educational research. We provide evidence that each of these goals is met. Student growth in theme knowledge is demonstrated through concept maps, questionnaires, and previously reported assessments. Improved writing ability is demonstrated using the spelling and grammar checking feature of Microsoft Word. The analysis of action research reports demonstrates that students are able to connect their action research project results to previous research.     

Young deafblind adults in action: becoming self-determined change agents through advocacy

Six young deafblind adults took a 1-week course on civic engagement and advocacy, which provided the focus for a participatory action research study with a collective case study design. They selected advocacy topics, were briefed on these policy issues, and were paired with experienced mentors for meetings with legislators in Washington, DC. Eight themes were identified from constant comparative and in vivo analysis of classroom discussion notes, interviews, and journals: (a) defining advocacy and advocate, (b) rights and equality, (c) expectations, (d) role of education in change, (e) deafblind expertise, (f) characteristics of effective change agents, (g) advocacy is teamwork, (h) future advocacy. In the classroom, the participants learned about policy issues, communication considerations, and leadership, then applied this knowledge in the legislative arena. Through the advocacy process, they learned to apply their personal strengths as advocates and experienced the importance of teamwork in advocacy.     

Learning environment,motivation, and achievement in high school science

In a study of the relationship between high school students' perceptions of their science learning environments and their motivation, learning strategies, and achievement, 377 students in 22 introductory science classrooms completed surveys in the fall and spring of their ninth‐grade year. Hierarchical linear regression was used to model the effects of variables at both the classroom and individual level simultaneously. High intraclass agreement (indicated by high parameter reliability) on all classroom environment measures indicated that students shared perceptions of the classroom learning environment. Controlling for other factors, shared perceptions that only the most able could succeed in science classrooms and that instruction was fast‐paced and focused on correct answers negatively predicted science achievement, as measured on a districtwide curriculum‐linked test. Shared perceptions that classrooms focused on understanding and independent thinking positively predicted students' self‐reported satisfaction with learning. Implications of these results for both teaching and research into classroom environments are discussed. © 2003 Wiley Periodicals, Inc. J Res Sci Teach 40: 347–368, 2003

Effects of Maternal Employment on Maternal and Two-Year-Old Child Behavior

94 mothers with 2-year-old children were interviewd about their employment, role satisfaction, and social support and were observed in their homes at dinnertime and in a laboratory compliance task. Hierarchical multiple regressions were used to test main effects of employment, hours employed, and their interactions. Maternal employment adversely affected maternal behavior when satisfaction with social support or with the work role was low, but only in the laboratory. Positive main effects of employment on maternal behavior were observed in the home: employed mothers used less power assertion with their children. Mothers who worked longer hours used more guidance and were more responsive to their children in both settings. In both settings, the effect of poor-quality care on child behavior was greater when mothers were employed, and, in the laboratory, boys of employed mothers were more defiant than boys of nonemployed mothers and girls of employed mothers. Boys with more than one current arrangement were more likely than similarly situated girls to be defiant in the laboratory, but they were also less likely than girls to be cared for by fathers.     

The Developmental Sequence and Relations Between Gesture and Spoken Language in Toddlers With Autism Spectrum Disorder

In typical development, gestures precede and predict language development. This study examines the developmental sequence of expressive communication and relations between specific gestural and language milestones in toddlers with autism spectrum disorder (ASD), who demonstrate marked difficulty with gesture production and language. Communication skills across five stages (gestures, word approximations, first words, gesture-word combinations, and two-word combinations) were assessed monthly by blind raters for toddlers with ASD participating in an randomized control trial of parent-mediated treatment (N = 42, 12–30 months). Findings revealed that toddlers acquired skills following a reliable (vs. idiosyncratic) sequence and the majority of toddlers combined gestures with words before combining words in speech, but in contrast to the pattern observed in typical development, a significant subset acquired pointing after first words.     

Learning to be critically reflective: exploring fiction writing and adult learning

Many educators in adult, community and higher education contexts are concerned with fostering reflective learning amongst their students. This paper explores the concept of critical reflection and considers how engaging with fiction may be an innovative pedagogical approach to support critical learning opportunities. Drawing upon interviews with fiction writers, ways in which critical reflection may be encouraged in connection to reading and writing fiction are taken up by exploring three different thematic areas that relate to a Habermasian framework of knowledge constitutive approaches to learning. These different areas can be categorised as (a) technical-rational, (b) humanistic and (c) critical or emancipatory. The first of these considers critical reflection as a way to develop technical capacities as a creative writer. The next section takes up a humanistic framework to explore the value of individual and collective learning opportunities to enhance personal growth and critical reflection. The third area of discussion considers a deeper critical or emancipatory framework of learning through critical reflection which may lead to social change. The paper concludes by considering the value of arts-informed adult education approaches, such as those related to fiction writing, to enhance the development of critical reflection amongst adult learners.     

‘Just turn to us’: the persuasive features of contract cheating websites

Academic integrity is important to universities and students must abide by codes of academic conduct around assessment. Students are, however, subject to multiple pressures around assessment, some of which can push them to cheat. Modern contract cheating websites are the fronts for sophisticated, commercial operations that offer individually written assessment items for a fee; to combat their use we need a better understanding of the tools they use to persuade students to become customers. In this study we examined the persuasive features of 11 highly-visible contract cheating websites and mapped these features to a previously used persuasiveness framework. We find that contract-cheating websites use a variety of credibility, interactive and informative features designed to persuade students to use their services. In addition, the sites offer low-cost, customisable products available in very short timeframes. We suggest ways in which educators can encourage academic integrity by talking with their students about how the websites promulgate their ‘just turn to us’ message.
