Harnessing Yik Yak for Good: A Study of Students’ Anonymous Library Feedback

This study explores academic libraries’ potential uses of the mobile application Yik Yak, with particular focus on patrons’ anonymous feedback about library services and spaces. Over a 232-day period, the authors observed the Yik Yak feed for their university and recorded all yaks related to the library. A content analysis of the 249 library-related yaks found six distinct purposes that these library-related yaks served, from the perspective of the patron, which are of interest to the library: asking questions about library services; reporting problems with library spaces; reprimanding violations of and encouraging adherence to library policies; sharing compliments about library services; demons-trating need for improved library services; and discussing and offering feedback about library programs. This study reveals several opportunities for academic libraries to engage with Yik Yak in order to serve their patrons better, including providing virtual reference services, monitoring problems within the building, developing proactive approaches to policy enforce-ment, gathering honest and continuous feedback about the library's strengths, and identifying opportunities to improve and expand services. Implications for practice are discussed.     

Whiteboards,Blanket Forts,and Autonomy: Using Self-Determination Theory to Improve Library De-Stress Programming

In recent years, librarians at Valparaiso University have adopted a user-centered programming model, allowing students to choose their own library de-stress programs during finals. After several semesters of using this approach, the authors sought to examine whether students felt a sense of agency in suggesting and voting on programs and whether this agency affected students’ motivation to attend de-stress programs. The authors conducted two focus groups with undergraduate students. Results suggest that most students are more interested in attending programs that they personally suggested or voted for, deriving intrinsic rewards from the autonomy of having their voices heard.     

Water Quality Statistics

Water quality experiments, especially the use of macroinvertebrates as indicators of water quality, offer an ideal context for connecting statistics and science. In the STAR program for secondary students and teachers, water quality experiments were also used as a context for teaching statistics. In this article, we trace one activity that uses virtual streams and repeated sampling to develop the notion of a hypothesis test for one proportion.     

Attitudes of high-school students taught using traditional and reform mathematics curricula in middle school: a retrospective analysis

This paper presents findings from a larger research project that provides insight into the attitudes of high-school students who were taught using different types of mathematics curricula when they were in middle school. A total of 44 12th-grade students from 10 high schools in the same urban school district were interviewed. Eighteen (41%) of them had been taught using a reform curriculum in middle school and 26 (59%) had been taught using a more traditional curriculum. Using Di Martino and Zan’s three-dimensional model for attitude, we found that the high-school seniors who had been taught using the reform curriculum in middle school harbored attitudes toward mathematics that differed significantly from the attitudes of those who had been taught using a traditional curriculum in middle school. Our analysis of the student interviews culled seven themes that provide fine-grained information about the students’ attitudes toward mathematics. Significantly greater percentages of reform students than traditional students had a relational Vision of mathematics as opposed to an instrumental Vision; however, there was no significant difference between the proportions of reform and traditional students who had a positive Emotional Disposition toward mathematics or a positive Perceived Competence in mathematics.     

Fostering Community College Leaders: An Examination of Leadership Development Programs

The study reported in this paper identifies leadership development practices within community colleges by surveying North Carolina community college presidents and evaluating an individual North Carolina community college's leadership institute. The results of the study indicate these community colleges indeed have an interest in leadership development activities for its employees, and the examined leadership institutes are quite effective and beneficial for its participants. Based upon these findings, two sets of recommendations are offered for fostering leadership initiatives within community colleges, namely, a focus on more significant topics for community college employees and developing a leadership learning community within a community college.     

Cloning the Professor,an Alternative to Ineffective Teaching in a Large Course

Pedagogical strategies have been experimentally applied in large-enrollment biology courses in an attempt to amplify what teachers do best in effecting deep learning, thus more closely approximating a one-on-one interaction with students. Carefully orchestrated in-class formative assessments were conducted to provide frequent, high-quality feedback that allows students to accurately diagnose the current state of their understanding of fundamental biological concepts and make specific plans to remedy any deficiencies. Teachers can also assume responsibility to guide out-of-class study among classmates by promoting Elaborative Questioning, an inquiry exchange that permits misconceptions to be identified and corrected and that promotes long-lasting metacognitive and analytical thinking skills. Data are presented that demonstrate the positive impact of these innovations on student performance and affect.     

Noise avoidance in the C57BL/6J mouse

Noise was evaluated as an aversive stimulus in the C57BL/6J mouse, using a simple escape/avoidance procedure in which mice could terminate noise by entering and remaining in a designatedsafe area (corner or side) of a square apparatus. Exposed to pulsed noise of 87.5–90 dB, mice spent 45%–50% of total corner time in the safe corner or approximately 80% of total time in the safe side. Acquisition was significantly faster with moderate intensities of pulsed noise (87.5–90 dB) than it was with high-intensity pulsed noise (100 dB). In comparisons of continuous as opposed to pulsed noise, acquisition was significantly faster with continuous (87.5-dB) noise than it was with pulsed noise, and continuous noise was shown in a choice procedure to be more aversive. Continuous noise caused significant, though not severe, suppression of activity, but pulsed noise caused virtually none. Thus, pulsed noise is a mildly aversive stimuhis for C57BL/6J mice and may have promise for the study of stress-induced behaviors in freely moving animals, but continuous noise is clearly more effective for rapid short-term conditioning.     

Rethinking exams and letter grades: how much can teachers delegate to students?

In this article we report a 3-yr study of a large-enrollment Cell Biology course focused on developing student skill in scientific reasoning and data interpretation. Specifically, the study tested the hypothesis that converting the role of exams from summative grading devices to formative tools would increase student success in acquiring those skills. Traditional midterm examinations were replaced by weekly assessments administered under test-like conditions and followed immediately by extensive self, peer, and instructor feedback. Course grades were criterion based and derived using data from the final exam. To alleviate anxiety associated with a single grading instrument, students were given the option of informing the grading process with evidence from weekly assessments. A comparative analysis was conducted to determine the impact of these design changes on both performance and measures of student affect. Results at the end of each year were used to inform modifications to the course in subsequent years. Significant improvements in student performance and attitudes were observed as refinements were implemented. The findings from this study emphasized the importance of prolonging student opportunity and motivation to improve by delaying grade decisions, providing frequent and immediate performance feedback, and designing that feedback to be maximally formative and minimally punitive.
