Attenuation by contextual cues of retroactive interference of a conditional discrimination in rats

We investigated the effect of associating unique contextual cues with an interpolated learning task on retroactive interference in long-term memory. Rats were originally trained in a two-bar operant chamber with an auditory conditional discrimination stimulus. During interpolated learning, which occurred in either the original or a new context, some rats were trained on a probability learning task that did not include the auditory stimuli present during original learning. Subsequent retraining on the original conditional discrimination task in the original context showed that (1) significant retroactive interference occurs in rats, and (2) the presence of unique contextual cues during interpolated learning significantly reduces this interference. These results extend the conditions under which the susceptibility to retroactive interference can be altered by contextual cues.     

Deepening kindergarteners' science vocabulary: A design study

Early, effective instruction to introduce both science vocabulary and general academic language may help children build a strong conceptual and linguistic foundation for later instruction. In this study, a design research intervention was employed to expose children to a variety of interrelated science content words to increase both the breadth and the depth of their vocabularies. This 8-week intervention targeted specific science content vocabulary development through adapting teachers' practices to include use of three instructional techniques: Teachers interactively read aloud information books, engaged students in conversation, and provided hands-on science activity centers. Results demonstrated that children deepened their understanding of the targeted vocabulary words.     

SCALE‐UP OF SAFE & CIVIL SCHOOLS’ MODEL FOR SCHOOL‐WIDE POSITIVE BEHAVIORAL INTERVENTIONS AND SUPPORTS

This study evaluated the scale‐up of a Safe & Civil Schools Foundations: Establishing Positive Discipline Policies positive behavioral interventions and supports initiative through 4 years of “real‐world” implementation in a large urban school district. The study extends results from a previous randomized controlled trial that established the effectiveness of the Safe & Civil Schools program in 32 elementary schools in the same district. This study emphasizes the application and evaluation of the program in regular district schools. Four‐year results indicate that elementary, middle, and high schools experienced moderate but steady improvements in (a) school discipline, (b) student safety policy and training, (c) staff perceptions of student behavior, and (d) student suspension and chronic tardiness rates. With few exceptions, improvements occurred after schools began Safe & Civil Schools Foundations training, and more years of training were associated with larger cumulative improvements in school and student outcomes. Given that similar effects were observed in schools with and without random assignment of training, and only after training began, we concluded that the improvements stem from Safe & Civil School's Foundations training.     

Assessing the added value of the self-system model of motivational development in explaining school engagement among students at risk of early leaving from education and training

European Journal of Psychology of Education - Tackling early leaving from education and training (ELET) is one of the headline targets for education policy in the European Union. Although ELET...     

Studying the effects of early child care experiences on the development of children of color in the United States: toward a more inclusive research agenda

Evidence is presented of the different cultural and ecological contexts affecting early child care for families of color. It is argued that improvements on previous research require a fundamental shift in how race, ethnicity, and culture as psychological variables are examined. Furthermore, to avoid the pitfalls and failures of previous research, new research must incorporate expanded models of child care and development in childhood. The integrative model of development for children of color proposed by Garcia Coll et al. (1996) is presented as a basis for developing more specific ecological models relevant to addressing child care issues in ethnic minority families. Finally, priority areas for future research are recommended to stimulate and enable child care researchers to adopt a more inclusive view of child care and its effects.     

Casual Games and Casual Learning About Human Biological Systems

Casual games are everywhere. People play them throughout life to pass the time, to engage in social interactions, and to learn. However, their simplicity and use in distraction-heavy environments can attenuate their potential for learning. This experimental study explored the effects playing an online, casual game has on awareness of human biological systems. Two hundred and forty-two children were given pretests at a Museum and posttests at home after playing either a treatment or control game. Also, 41 children were interviewed to explore deeper meanings behind the test results. Results show modest improvement in scientific attitudes, ability to identify human biological systems and in the children’s ability to describe how those systems work together in real-world scenarios. Interviews reveal that children drew upon their prior school learning as they played the game. Also, on the surface they perceived the game as mainly entertainment but were easily able to discern learning outcomes when prompted. Implications for the design of casual games and how they can be used to enhance transfer of knowledge from the classroom to everyday life are discussed.     

Air Toxics Under the Big Sky: examining the effectiveness of authentic scientific research on high school students’ science skills and interest

Air Toxics Under the Big Sky is an environmental science outreach/education program that incorporates the Next Generation Science Standards (NGSS) 8 Practices with the goal of promoting knowledge and understanding of authentic scientific research in high school classrooms through air quality research. This research explored: (1) how the program affects student understanding of scientific inquiry and research and (2) how the open-inquiry learning opportunities provided by the program increase student interest in science as a career path. Treatment students received instruction related to air pollution (airborne particulate matter), associated health concerns, and training on how to operate air quality testing equipment. They then participated in a yearlong scientific research project in which they developed and tested hypotheses through research of their own design regarding the sources and concentrations of air pollution in their homes and communities. Results from an external evaluation revealed that treatment students developed a deeper understanding of scientific research than did comparison students, as measured by their ability to generate good hypotheses and research designs, and equally expressed an increased interest in pursuing a career in science. These results emphasize the value of and need for authentic science learning opportunities in the modern science classroom.     

Whose reality counts? Local educators as researchers on the quality of primary education

This article describes a methodology that local educators can use to conduct structured analytic research on the quality of primary education. The methodology has been developed by four twenty-person teams of local educators who carried out studies in rural regions of Madagascar, Mozambique, Tanzania and Uganda. In addition to describing the methodology, the article presents short summaries of the researchers’ conclusions and recommendations. However, its main purpose is to share the methodology that has evolved. The methodology is qualitative, but a simple quantitative measure of relationship between binary variables (Yule’s Q) was used to test the researchers’ qualitative findings. It is this tool that provoked the most significant reflection among the researchers in each group. In general, the results of the four studies corroborate other research on the factors that influence student outcomes in primary schools in Sub-Saharan Africa. More importantly, the studies’ results demonstrate that the methodology offers practicing educators a tool that helps them define, collect, and rigorously analyse empirical information to reach shared insights about their schools and then to formulate practical recommendations about what to do to improve student learning.
