How temporal and spatial aspects of presenting visualizations affect learning about locomotion patterns

Two studies investigated the effectiveness of dynamic and static visualizations for a perceptual learning task (locomotion pattern classification). In Study 1, seventy-five students viewed either dynamic, static-sequential, or static-simultaneous visualizations. For tasks of intermediate difficulty, dynamic visualizations led to better classification performance than static-sequential visualizations, but not than static-simultaneous visualizations. To test whether the temporal aspects of presenting static-simultaneous visualizations (i.e., their permanent visibility) or their spatial aspects (i.e., their arrangement in rows) accounted for this effect, Study 2 investigated three additional static-simultaneous conditions. Seventy-five students viewed static-simultaneous visualizations presented either in columns, matrices, or circles. For tasks of intermediate difficulty dynamic visualizations outperformed pictures presented in columns, matrices, and circles, but not the rows format. Accordingly, for learning about locomotion patterns, dynamic visualizations are better suited than most, but not all static visualization formats. From a practical point of view, effort should be invested into the design of static-simultaneous visualizations to further optimize instructional materials.

Suicidal Behavior and Help Seeking Among Diverse College Students

Suicidal and help‐seeking behaviors of students of color remain a significant problem on college campuses. Self‐reported suicidal experiences and help‐seeking behavior of diverse students are examined on the basis of results from a national survey of college student mental health. The results suggest significant differences in the expression of suicidal thoughts and behavior across racial and ethnic groups and different experiences in their referral for, and utilization of, professional help.

DEVELOPMENT, EVALUATION, AND VALIDATION OF A PAPER-AND-PENCIL TEST FOR MEASURING TWO COMPONENTS OF BIOLOGY TEACHERS’ PEDAGOGICAL CONTENT KNOWLEDGE CONCERNING THE “CARDIOVASCULAR SYSTEM”

One main focus of teacher education research concentrates on teachers’ pedagogical content knowledge (PCK). It has been shown that teachers’ PCK correlates with teaching effectiveness as well as with students’ achievement gains. Teachers’ PCK should be analyzed as one of the main important components to evaluate professional development programs. On this account, it is necessary to develop standardized measures of biology teachers’ topic-specific PCK that are labor-efficient. This paper presents a study on the development, evaluation, and validation of a paper-and-pencil test to measure biology teachers’ declarative PCK on the topic of blood and the human cardiovascular system. The development of the test was based, among other considerations, on a review of research literature on PCK and an analysis of 50 videotaped biology lessons. The final test instrument was comprised of 15 items distributed across 2 scales. The findings of the main study—with 93 preservice and in-service biology teachers and 12 biologists—confirmed that this measure of biology teachers’ declarative PCK was reliable, objective, and valid. In-service biology teachers scored higher on the test than preservice teachers (effect size Cohen’s d, 0.65) on one hand and, also, than biologists (Cohen’s d, 1.00) on the other hand. Future versions of this test should explore enlarging the scales and measuring procedural aspects of PCK.     

Peer Mentoring Styles and Their Contribution to Academic Success Among Mentees: A Person-Oriented Study in Higher Education

The purpose of our study was to explore peer mentoring styles and examine their contribution to academic success among mentees. Data were collected as part of a comprehensive evaluation of a peer mentoring program. The sample consisted of 49 mentors (advanced students) who supported 376 mentees (first year students) in small groups. Indicators for peer mentoring styles were constructed using mentee assessments of mentoring functions and mentor quality, and unobtrusive data gathered in an analysis of online mentoring activities and a content analysis of the quality of the online mentoring activities. Using cluster analyses, three distinct mentoring styles were identified: Motivating master mentoring, informatory standard mentoring, and negative minimalist mentoring. Motivating master mentors were shown to have a positive influence on success in the mentoring program among those mentees who failed two preliminary exams. Implications for the training of peer mentors in higher education are discussed.
