How students switch on and switch off in mathematics: exploring patterns and predictors of (dis)engagement across middle school and high school

Using growth modeling, this study examined trajectories of ‘switching on’ (aspirations) and ‘switching off’ (disengagement) in mathematics across middle school and high school. In addition, guided by principles under expectancy-value theory, the study sought to determine the extent to which patterns of growth differed by motivation (self-efficacy and valuing) and socio-educational attributes (gender, language background, and achievement). The sample comprised 194 students from four schools who participated in three rounds of data collection across five academic years of their schooling, spanning middle school and high school. In the main, mathematics aspirations declined over time while mathematics disengagement increased. However, initial levels of aspirations and disengagement and their rates of change over time were impacted by motivational and socio-educational factors. Salient findings and their implications for educational assessment and practice are discussed.     

Using Palm Technology in Participatory Simulations of Complex Systems: A New Take on Ubiquitous and Accessible Mobile Computing

This paper reports on teachers’ perceptions of the educational affordances of a handheld application called Participatory Simulations. It presents evidence from five cases representing each of the populations who work with these computational tools. Evidence across multiple data sources yield similar results to previous research evaluations of handheld activities with respect to enhancing motivation, engagement and self-directed learning. Three additional themes are discussed that provide insight into understanding curricular applicability of Participatory Simulations that suggest a new take on ubiquitous and accessible mobile computing. These themes generally point to the multiple layers of social and cognitive flexibility intrinsic to their design: ease of adaptation to subject-matter content knowledge and curricular integration; facility in attending to teacher-individualized goals; and encouraging the adoption of learner-centered strategies.     

Digital Citizenship: You Can’t Go Home Again

In the July/August 2011 edition of TechTrends, a group of AECT members and academic professionals explored the state of digital citizenship for students in K-12 through an article entitled: Digital Citizenship in K-12: It Takes a Village. Identified was a significant need for digital citizenship awareness by parents, educators, and students through a series of interviews, exploration of resources, reports, and surveys. In this current article, the purpose is to provide an updated perspective of the state of digital citizenship in the K-12 academic and professional environments as gathered from re-administering the 2010 survey and interviewing experts quoted in the 2010 article. Results showed the need for teaching digital citizenship at an earlier age, improved digital citizenship awareness by both educators and administrators, and a continued focus on the misuse and abuse of technology.     

Teacher‐Child Oral Reading Interactions: how do teachers typically tutor?

This paper reports the results of three studies which examine the behaviours of teachers when hearing children read. In the first study, we examine the tutoring behaviour of 55 teachers listening to 8‐14‐year‐old low progress readers. In the second study, we report results on 31 teachers listening to very low progress readers aged 9‐16 years and, in the third, we discuss the findings from 55 teachers listening to young average progress readers aged 4‐8 years. The results suggest that, for all three groups of readers, most teachers tend to respond immediately most of the time to reader errors, allowing little or no time for readers to self‐correct. Teachers tend to respond to errors with a prompt on most occasions but this is more likely with low and very low progress readers than with young, average progress readers. Relatively low rates of praise were apparent in all three groups. We also found that a large number of readers in all groups were inappropriately placed on book levels which were too easy or (less frequently) too difficult, as against an appropriate instructional level.     

On Location Learning: Authentic Applied Science with Networked Augmented Realities

The learning of science can be made more like the practice of science through authentic simulated experiences. We have created a networked handheld Augmented Reality environment that combines the authentic role-playing of Augmented Realities and the underlying models of Participatory Simulations. This game, known as Outbreak @ The Institute, is played across a university campus where players take on the roles of doctors, medical technicians, and public health experts to contain a disease outbreak. Players can interact with virtual characters and employ virtual diagnostic tests and medicines. They are challenged to identify the source and prevent the spread of an infectious disease that can spread among real and/or virtual characters according to an underlying model. In this paper, we report on data from three high school classes who played the game. We investigate students’ perception of the authenticity of the game in terms of their personal embodiment in the game, their experience playing different roles, and their understanding of the dynamic model underlying the game.     

“I think everybody is afraid of the unknown”: Early childhood teachers prepare for mainstreaming

Conclusion In conclusion, as early childhood teachers prepare to meet the “unknown” —mainstreaming—the early childhood community has an excellent opportunity to benefit from both past experiences and the research literature on mainstreaming and teacher change. This work suggests that teachers' feelings and attitudes about mainstreaming must be addressed in dynamic relation to their needs for information and skills as these change over time. Teachers, directors, and teacher educators need help in understanding that teachers' development and the development of the children they teach are inextricably linked. While these concepts have been explored previously, it is imperative that practitioners at all levels recognize their relevance at this critical juncture in the implementation of P.L. 99–457 and consider new and creative ways to translate them into practice. I feel... not just that I couldn't cope with it... but emotionally I don't think I could... Emotionally I think I would have a hard time, you know, going home and feeling good about myself when I know that there's this child [with disabilities in my classroom].     

Attentional enhancement in matching-to-sample: Facilitation in matching acquisition by sample-discrimination training

In three experiments, we examined how matching-to-sample by pigeons is affected by discrimination versus nondifferential training between the matching stimuli. In Experiment 1A, pigeons responding differentially to the sample stimuli off-baseline acquired accurate matching performances more rapidly than did pigeons responding nondifferentially to those same stimuli. In Experiment 1B, tests involving reversal of the off-baseline requirements demonstrated that the birds were primarily controlled in their matching choices by the sample stimuli. The results of Experiment 2 showed that off-baseline nondifferential training did not retard acquisition relative to comparable training between stimuli unrelated to the matching task. Together, these results suggest that discrimination training can facilitate matching acquisition by enhancing attention to the sample stimuli.     

Social Science Boot Camp: Development and Assessment of a Foundational Course on Academic Literacy in the Social Sciences

We developed a course, as part of our institution's core program, which provides students with a foundation in academic literacy in the social sciences: how to find, read, critically assess, and communicate about social science research. It is not a research methods course; rather, it is intended to introduce students to the social sciences and be better consumers of social science research. In this article, we describe the key learning objectives of this course, the basic content areas, and some of the innovative teaching and learning strategies used in the course. We also provide empirical evidence of the effectiveness of the course in meeting its learning objectives and of student responses to the course. Finally, we discuss some of the challenges in developing interdisciplinary core courses and offer suggestions for best practices for teaching social science literacy as part of the core curriculum.     

Using a cross section to train veterinary students to visualize anatomical structures in three dimensions*

A cross section was used to enhance three‐dimensional knowledge of anatomy of the canine head. All veterinary students in two successive classes (n = 124) dissected the head; experimental groups also identified structures on a cross section of the head. A test assessing spatial knowledge of the head generated 10 dependent variables from two administrations. The test had content validity and statistically significant interrater and test–retest reliability. A live‐dog examination generated one additional dependent variable. Analysis of covariance controlling for performance on course examinations and quizzes revealed no treatment effect. Including spatial skill as a third covariate revealed a statistically significant effect of spatial skill on three dependent variables. Men initially had greater spatial skill than women, but spatial skills were equal after 8 months. A qualitative analysis showed the positive impact of this experience on participants. Suggestions for improvement and future research are discussed. © 2002 John Wiley & Sons, Inc. J Res Sci Teach 39: 10–34, 2002
