Practical independent research projects in science: a synthesis and evaluation of the evidence of impact on high school students

Practical independent research projects (IRPs) are a feature of school science in a number of countries. To assess the impact of IRPs on students, a systematic review of the literature was undertaken. Thirty-nine papers met the review inclusion criteria, reporting on work from twelve countries. The review indicates that IRPs are often associated with wider initiatives such as authentic science, problem-based learning, and project-based learning. There is considerable variability in the nature of IRP work in relation to focus, models of provision, assessment, the involvement of external partners such as universities and employers, and funding, and this diversity affects judgements on the quality of the evidence base on impact. The majority of the research reviewed explored areas such as conceptual understanding, motivation to study science once it is no longer compulsory and attitudes to science, and the development of practical skills. Benefits were identified in relation to the learning of science ideas, affective responses to science, views of pursuing careers involving science, and development of a range of skills. Studies focusing on traditionally under-represented groups indicated that such students felt more positive about science as a result of undertaking IRPs. The review findings indicate that further work is needed to enhance the quality of the available evidence, to consider the ways in which IRPs can be validly assessed, to explore more fully the potential benefits for traditionally under-represented groups, and to explore more fully the potential longer-term benefits of participation in IRPs at high school level.     

Voices from the Field: Perspectives of U.S. Kinesiology Chairs on Opportunities,Challenges, and the Role of Mentoring in the Chair Position

This study examined perspectives of U.S. collegiate kinesiology department chairs (n = 54/144; 37.5% response rate) relative to: (a) opportunities and most enjoyable aspects of being a department chair, (b) challenges and least enjoyable aspects of being a department chair, and (c) perspectives on mentoring. The majority of participants enjoyed their chair role (90%) and did not aspire to advance in administration (61%). Job-related opportunities included mentoring others, facilitating department success, and leading initiatives (e.g., curricula, policies, and finances). Job-related challenges included a lack of university support, personnel issues, and urgent requests for information. Many had a mentor for a long time (mean = 7.9 ± 7.6 years; range 1 to 28 years), and the majority (71%) did not consider their dean a mentor. Protégés appreciated their mentors’ experience, listening skills, and willingness to share information, advice, and empathy. Results from this study provide helpful information for serving as a kinesiology chair.     

Hostility, hostile detachment, and conflict engagement in marriages: effects on child and family functioning

This study examined the relations between patterns of marital communication, child adjustment, and family functioning. Couples with a 4- or 5-year-old child were divided into three groups (N = 126) based on observed patterns of emotional communication: Hostile couples showed a cumulative increase in negative speaker behaviors over the course of a high-conflict marital discussion; hostile-withdrawn couples showed a cumulative increase in both negative speaker and negative listener behaviors over the course of the interaction; and engaged couples showed a cumulative increase in both positive speaker and listener behaviors over the course of the interaction. The families of these three types of couples were then compared on child outcomes (i.e., peer relations, behavior problems), parenting quality, co-parenting quality, and family-level functioning. Differences in marital violence and marital satisfaction between marital couples were also examined in relation to family risk. Families in which couples were hostile-detached showed the most negative outcomes. Hostile-detached couples were more likely than hostile or conflict-engaging couples to use more power-assertive methods of discipline; to be ineffective in co-parenting their child; to have family units that were less cohesive, less playful, and more conflictual; and to have children that exhibited behavior problems. Results also indicated that marital typology still accounted for significant variance in child outcome after controlling for marital violence and marital satisfaction. Differences in the absolute degree of negative behaviors also did not account for results. Findings are discussed in terms of the detrimental impact of marital conflict on child and family functioning.     

Vocabulary does not complicate the simple view of reading

Gough and Tunmer’s (1986) simple view of reading (SVR) proposed that reading comprehension (RC) is a function of language comprehension (LC) and word recognition/decoding. Braze et al. (2007) presented data suggesting an extension of the SVR in which knowledge of vocabulary (V) affected RC over and above the effects of LC. Tunmer and Chapman (2012) found a similar independent contribution of V to RC when the data were analyzed by hierarchical regression. However, additional analysis by factor analysis and structural equation modeling indicated that the effect of V on RC was, in fact, completely captured by LC itself and there was no need to posit a separate direct effect of V on RC. In the present study, we present new data from young adults with sub-optimal reading skill (N = 286). Latent variable and regression analyses support Gough and Tunmer’s original proposal and the conclusions of Tunmer and Chapman that V can be considered a component of LC and not an independent contributor to RC.     

Using Computer Assisted Instruction to Compare the Inventive Model and the Radical Constructivist Approach to Teaching Physics

This paper introduces a new way of evaluating instructional strategies by using computers. Two basic theories, instructivism and constructivism, are discussed and critically evaluated in terms of their effectiveness in conceptual learning. Despite the current popularity of constructivism, the radical form of it is criticized in this paper. The advantages and limitations of these two approaches, especially the radical forms of constructivism, are outlined. After borrowing some ideas from other effective conceptual change models, an integrative model for conceptual learning (the Inventive Model) is introduced. Two versions of multimedia physics software are developed by the authors. The first version is based on the Inventive Model and the second version based on a radical constructivist model. The effectiveness of the Inventive Model was compared with the radical constructivist approach and conventional science instruction. Students' log files were analyzed to investigate the nature and the processes of the conceptual change. A conceptual test and a knowledge test were used to compare the groups. The quantitative results showed the superiority of the Inventive Model over the other models in conceptual learning and the superiority of conventional instruction in learning the basic knowledge. The qualitative analysis showed that only the Inventive Model lead to coherent conceptual learning. It was concluded that the process of conceptual change is gradual and continuous. Analysis of students' log files revealed no moments of dramatic change in students' conceptions.     

Introduction to the Special Issue on Teaching Inquiry (Part I): Illuminating Inquiry

Abstract

We provide an introduction to the special issue on Teaching Inquiry, through its motivation and themes. We focus here on Part I: Illuminating Inquiry.     

Predictive text entry with PAL and children with learning difficulties

Nine case studies were conducted to evaluate the usefulness of a predictive text entry program within a classroom environment. The program, PAL, was found to be very successful in eight of the cases. For children with poor motor control, the key-saving aspects speeded up text creation. Of even greater significance was the extent to which children with severe spelling problems were helped. They were able to produce much higher quality written work with a substantial reduction in the number of spelling errors. This provided great motivation for the children, and teaching staff commented on their improved confidence and attention span, as well as stimulation of language and vocabulary development. One of the children was on the verge of being classified as a non-reader and, although progress was slow, a significant improvement in the child's work was observed.
