Disruptive silence: deepening experiential learning in the absence of technology

Technology plays an integral role in the lives of the majority of the US population. As technology becomes integrated into young people’s lives, questions arise regarding its effects on learning. This exploratory study draws on interviews with students who attend university in the United States to determine how separating students from technology deepens experiential learning. Participants were interviewed following a study abroad course to New Zealand, during which they were disconnected from technologies such as cell phones, the Internet and social media. In the interviews, students discussed their feelings of being disconnected and describe how disconnecting impacted their overall experience. Participants agreed that disconnecting from technology had positive effects on experiential learning and the global experience. Major themes that emerged include students’ enhanced immersion and engagement, the value of disconnection in providing opportunities for personal growth and the difficulty of initial separation from technology as a result of conditioning.     

Messy learning: Preservice teachers’ lesson-study conversations about mathematics and students

Research about lesson study and other forms of collaborative, practice-based professional development has tended to focus on identifying structures that support teacher learning. This study builds on this work by examining preservice elementary teachers’ efforts to conduct lesson studies in mathematics. Analysis showed that the structures of the lesson study project supported some groups in developing mathematical and equity lenses for looking at teaching; however, the use of these lenses simultaneously led to productive and problematic learning. This finding suggests that future research focus on challenges present in collaborative, practice-based work even when productive structures are in place.     

Shifting Lenses to Deepen Reflection and Connection in Human Sexuality Education

Photovoice, a participatory action research method, supports deep, personal reflection through the use of photography, personal narrative development, and group discussion. This lesson plan describes the use of Photovoice as a pedagogical tool in an undergraduate human sexuality course. The goal of this activity is to encourage students to 1) think beyond the texts presented in class, 2) make critical connections to their own lived experience and community context, and 3) deepen reflection through sharing and discussing with others. The lesson plan describes the process of bringing Photovoice into the classroom as well as student insights on the activity.     

How Accurate Is Peer Grading?

Previously we showed that weekly, written, timed, and peer-graded practice exams help increase student performance on written exams and decrease failure rates in an introductory biology course. Here we analyze the accuracy of peer grading, based on a comparison of student scores to those assigned by a professional grader. When students graded practice exams by themselves, they were significantly easier graders than a professional; overall, students awarded ≈25% more points than the professional did. This difference represented ≈1.33 points on a 10-point exercise, or 0.27 points on each of the five 2-point questions posed. When students graded practice exams as a group of four, the same student-expert difference occurred. The student-professional gap was wider for questions that demanded higher-order versus lower-order cognitive skills. Thus, students not only have a harder time answering questions on the upper levels of Bloom's taxonomy, they have a harder time grading them. Our results suggest that peer grading may be accurate enough for low-risk assessments in introductory biology. Peer grading can help relieve the burden on instructional staff posed by grading written answers-making it possible to add practice opportunities that increase student performance on actual exams.     

Comparisons of the IQ and vocabulary scores on Wechsler Preschool and Primary Scale of Intelligence-Revised and Peabody Picture Vocabulary Test-Revised

The Wechsler Preschool and Primary Scale of Intelligence-Revised and the Peabody Picture Vocabulary Test-Revised were administered to 51 preschool, kindergarten, first-grade, and second-grade students. Although 2 of 4 Pearson correlations between these two instruments were statistically significant, they may not be of practical significance.     

Sex,drugs and science: the IOC’s and IAAF’s attempts to control fairness in sport

Abstract

This paper traces the history of two important policies in sport: rules against drugs and ‘ambiguous’ athletes in women’s events. We identify three phases in the work of the International Olympic Committee’s and International Amateur Athletic Federation’s medical committees: (1) from the mid-1960s to the 1970s, the medical grounding of the committees and the members’ worldviews encouraged the groups to enlist scientific techniques to solve drug use and sex ambiguity issues; (2) from the 1970s to the 1980s, administrative confusion underscored both committees, but scientific personnel gained legitimacy and furthered their own agendas; and (3) from the 1980s to the mid-1980s, the seeds of diversion in sex and drug tests were sown. The central finding of this study is that the stakeholders who shaped anti-doping and sex testing policies took for granted concerns regarding ethics and instead increasingly relied upon medical, scientific, and technical practices to define and control fairness in sport.
