How Much Have They Retained? Making Unseen Concepts Seen in a Freshman Electromagnetism Course at MIT

The introductory freshmen electromagnetism course at MIT has been taught since 2000 using a studio physics format entitled TEAL—Technology Enabled Active Learning. TEAL has created a collaborative, hands-on environment where students carry out desktop experiments, submit web-based assignments, and have access to a host of visualizations and simulations. These learning tools help them visualize unseen electromagnetic concepts and develop stronger intuition about related phenomena. A previous study has shown that students who took the course in the TEAL format (the experimental group) gained significantly better conceptual understanding than those who took it in the traditional lecture-recitation format (the control group). The present longitudinal study focuses on the extent to which these two research groups (experimental and control) retain conceptual understanding about a year to 18 months after finishing the course. It also examines students attitudes about whether the teaching format (TEAL or traditional) contributes to their learning in advanced courses. Our research has indicated that the long-term effect of the TEAL course on students’ retention of concepts was significantly stronger than that of the traditional course. This research is significant because it documents the long-term cognitive and affective impact of the TEAL studio physics format on learning outcomes of MIT students.

Evaluating climate change behaviors and concern in the family context

Abstract

Although research suggests that family dynamics likely play a role in shaping children’s behaviors, few studies focus on environmental behaviors, and none to our knowledge investigate how parents shape climate change mitigation behaviors among their children. We begin to fill this gap through a quantitative case study using matched household-level survey data from 182 coastal North Carolina families (n?=?241 parents aged 29–77; n?=?182 students aged 11–14) associated with 15 middle school science teachers. Family climate change discussions, parent behaviors, and children’s climate change concern levels predicted the degree to which children will participate in individual-level climate mitigation behaviors. These results provide evidence that promoting climate-related conversations within households may promote climate action even when parents are apathetic about climate change. Similarly, parental behaviors, but not their concern levels, were important predictors of adolescent behaviors. This study highlights novel ways that family dynamics may promote climate change mitigating behaviors and a new pathway to promoting climate mitigation at familial, and ultimately, societal levels.     

Place-Based Stewardship Education: Nurturing Aspirations to Protect the Rural Commons

In this mixed-methods study, we examine the potential of place-based stewardship education (PBSE) for nurturing rural students’ community attachment and aspirations to contribute to the preservation of the environmental “commons.” Analyzing pre- and post-experience surveys (n = 240) and open-ended responses (n = 275) collected from middle school students in a Northeast Michigan school district, we found significant increases in students’ environmental sensitivity, environmentally responsible behaviors, community attachment, and confidence in their capacities for civic action. Analyses of open-ended responses pointed to the potential of PBSE to nurture students’ identification with their community and to increase their commitment to stewardship of their community's natural resources. This study makes a unique contribution to the literature on rural schools by focusing on the environmental commons and younger generations’ commitments to preserve it as an asset of rural communities. By linking students’ learning with collective action to preserve the environmental commons, PBSE can expand students’ aspirations for the kind of world they want to live in and the roles they might play in it.     

For Science and Self: Youth Interactions with Data in Community and Citizen Science

In youth-focused community and citizen (YCCS) youth in classrooms and community-based programs produce data that scientists, resource managers and community members will use. This “nested” data situates learners’ scientific activity within larger datasets, projects, and communities, with consequences for youth agency. To document opportunities for agentive learning with data in YCCS, we report on how youth interact with data across eight school and community-based project sites and how youth talk about their data and work. From analysis of 54 participant interviews, we found that youth perceived the data they produced as being used for: (1) broader scientific work, (2) their own learning, and (3) community endeavors. Nested uses of data were most meaningful when youth interacted with end users, were exposed to the larger datasets to which they contributed, or took action linked to data. Not all youth saw, believed, or valued that data would be used by others. Framing of task and purpose, nature of engagement with community users, data production protocols, and level of emphasis on youth-identified questions may contribute to youth perceptions and can foster or undermine conditions for learner agency. The results shed light on when and how conditions for expansive learning and agency get established.     

Motivation coaching training for instructional coaches: a pilot study of motivational interviewing skills training

In our paper we describe a newly developed teacher coaching model that provides training on motivational interviewing (MI) to improve instructional coaches’ effectiveness with classroom teachers. Participants were 38 coaches who completed a three-day coaching training. At pre- and post-test, the participants completed role plays with an actor who played the role of a new teacher. Then, these sessions were coded for MI-consistent behavior. The results of our study revealed that the majority of the coaching conversations were inconsistent with effective MI. At baseline, conversations were primarily characterized by questions (60%) followed by attempts to persuade without permission (20%). Following training, coaches did not change their conversational style. Because an MI-inconsistent conversation style is associated with decreased self-efficacy and motivation for change, the findings suggest a need to help coaches develop interactions that are more consistent with best practices of MI.     

Immersion Learning in Social Work Education: A Pedagogical Tool for Enriching Knowledge and Practice Skills among BSW Students

Immersion learning is one form of experiential education and has great utility in social work education. However, there is limited research on student learning outcomes from immersion learning courses in social work education. This ethnographic research describes an immersion learning course offered to BSW students (N = 9) and the learning outcomes gained. This semester-long course focused on macrolevel practice with people experiencing poverty, homelessness, and the sexual exploitation of women. As part of this course, students went on a weeklong immersion trip, where they visited a dozen human service organizations and interacted with people experiencing poverty and homelessness. Qualitative analysis produced three findings. First, students reported that these interactions helped them realize their biases and impacted their understanding of poverty. Second, students reported enhanced social work practice skills, such as cultural competency, self-awareness, and interpersonal expertise. They also gained a better appreciation for macrolevel practice. Third, students reported a better understanding of how to deploy classroom knowledge in practice and how to apply what they learned back in the classroom. These findings have implications for undergraduate social work education and how immersion learning programs can be a tool for enriching both knowledge and practice skills.     

The Dangerous Individual('s) Dog: Race,Criminality and the ‘Pit Bull’

Abstract

Though it is generally acknowledged that there is a relationship between racist discourse and the figure of the non-human animal, this relationship is almost always assumed to be analogical: oppressed groups are compared with or treated as non-human animals. But the recent dogfighting case against NFL Quarterback Michael Vick and the attendant suspicion of ‘pit bulls’ suggests that racism today has a more complex relationship with (certain types of) animals than the analogy would capture. An analysis of this discourse both calls for and revises Foucault's notion of ‘the dangerous individual’ as an explanatory concept for contemporary racism. The concomitant revulsion toward both dogfighting and ‘pit bulls’ suggests an expression of fear of a perceived threat to normative whiteness, insofar as these ‘dangerous’ dogs are figured as carriers of the contagion of racial abnormality.     

Lower limb moments differ when towing a weighted sled with different attachment points

Sprinting while towing a sled improves sprinting parameters, however, only kinematic and temporal–spatial variables have been reported. The purpose of this study was to determine how lower extremity joint moment impulses alter when towing a sled compared to normal walking. Twelve participants walked normally, walked while towing a sled with a 50% body weight load attached at the waist, and with a 50% body weight load attached at the shoulders. Joint moment impulses were calculated for the hip, knee, and ankle. A mixed-model ANOVA with a between-subject factor of limb and repeated measures of condition was used to compare differences between limbs and towing conditions for each joint. Towing a sled increased joint moment impulses at the hip, knee, and non-dominant ankle. When compared with normal walking waist attachment increased hip extension moment impulse by 214.5% ( ? 3.31 vs. ? 10.41 Nms/kg), and shoulder attachment increased knee extension moment impulse by 166.9% (4.62 vs. 12.33 Nms/kg). The dominant limb produced greater knee extension moment impulse (p < 0.001), while the non-dominant limb produced greater hip extension (p < 0.001) and ankle plantarflexion moment impulse (p < 0.001) across all conditions. Results suggest that walking while towing may increase hip and knee extension strength.     

School‐based counseling of abused children

Abused children experience high rates of behavior, emotional, and learning problems but infrequently receive treatment. Most services provided to abused children and their families are not based on any clear evidence that they work. A number of evidence‐based treatments (EBTs), demonstrated to be safe and effective in treating a range of difficulties that present in children exposed to family violence, are appropriate for schools. We briefly review forms of abuse, describe EBTs appropriate for schools, and present a decision tree for deciding who to treat and how. © 2009 Wiley Periodicals, Inc.
