Verbal Final Exam in Introductory Biology Yields Gains in Student Content Knowledge and Longitudinal Performance

We studied gains in student learning over eight semesters in which an introductory biology course curriculum was changed to include optional verbal final exams (VFs). Students could opt to demonstrate their mastery of course material via structured oral exams with the professor. In a quantitative assessment of cell biology content knowledge, students who passed the VF outscored their peers on the medical assessment test (MAT), an exam built with 40 Medical College Admissions Test (MCAT) questions (66.4% [n = 160] and 62% [n = 285], respectively; p < 0.001);. The higher-achieving students performed better on MCAT questions in all topic categories tested; the greatest gain occurred on the topic of cellular respiration. Because the VF focused on a conceptually parallel topic, photosynthesis, there may have been authentic knowledge transfer. In longitudinal tracking studies, passing the VF also correlated with higher performance in a range of upper-level science courses, with greatest significance in physiology, biochemistry, and organic chemistry. Participation had a wide range but not equal representation in academic standing, gender, and ethnicity. Yet students nearly unanimously (92%) valued the option. Our findings suggest oral exams at the introductory level may allow instructors to assess and aid students striving to achieve higher-level learning.     

The effects of passive and active learning on student preference and performance in an undergraduate basic science course

Active learning is based on self-directed and autonomous teaching methods, whereas passive learning is grounded in instructor taught lectures. An animal physiology course was studied over a two-year period (Year 1, n = 42 students; Year 2, n = 30 students) to determine the effects of student-led seminar (andragogical) and lecture (pedagogical) teaching methods on students' retention of information and performance. For each year of the study, the course was divided into two time periods. The first half was dedicated to instructor-led lectures, followed by a control survey in which the students rated the efficiency of pedagogical learning on a five-point Likert scale from one (strongly disagree) to five (strongly agree). During the second period, students engaged in andragogical learning via peer-led seminars. An experimental survey was then administered to students using the same scale as above to determine students' preferred teaching method. Raw examination scores and survey results from both halves of the course were statistically analyzed by ANOVA with Newman-Keuls multiple comparison test. By the end of the study, student preference for peer-led seminars increased [mean ± SD: (2.47 ± 0.94)/(4.03 ± 1.36), P < 0.04], and examination scores significantly increased [mean ± SD: (73.91% ± 13.18)/(85.77 ± 5.22), P < 0.001]. A majority of students (68.8%) preferred a method that contained peer-led seminars and instructor-led lectures. These results may indicate that integration of active and passive learning into undergraduate courses may have greater benefit in terms of student preference and performance than either method alone.     

For Whom Are We Building These Gems? Redefining Impact at the Museo Textil de Oaxaca

Abstract Can museums still be valuable to populations that don’t visit them? The city of Oaxaca, Mexico is home to a flourishing museum scene, but despite a desire by those museum professionals to serve the Oaxacan community, the city’s museums largely lack a local visiting base. This article, which reflects on ethnographic fieldwork conducted in Oaxaca in 2010, explores the implications of the disjunction between intention, assumption, and reality in some of Oaxaca’s museums, especially the Museo Textil de Oaxaca, a small private textile museum in the city’s historical center. By considering the museum’s inherent value and its innovative attempts to tangibly impact a specific community outside of the museum edifice, I suggest a way to rethink impact in museums by, in effect, turning them inside out: shifting the focus away from “public value driven by a universal right to cultural access” ( Stein 2012, 219 ), toward more tangible, external outcomes, including direct interventions in the dynamic world beyond the quiet galleries.     

Contemporary practices in school psychology: A national survey of roles and referral problems

Eight hundred school psychologists who were members of the National Association of School Psychologists were mailed a survey designed to assess their roles, types of referrals, consultation practices, and crisis team involvement. Three hundred seventy (49%) completed surveys were analyzed. Assessment was the most common role followed distantly by consultation. Academic problems were the most frequent type of referral with reading being the most common concern. Of the behavioral referrals, externalizing problems were more frequent than internalizing concerns. Behavioral consultation was the most common model used but less than half of respondents follow all of the stages. Only forty percent use an evaluative component in consultation. A majority of the informants had some involvement with their schools' crisis team. Implications of these findings for training, professional development, and future roles are discussed. © 2002 Wiley Periodicals, Inc.     

Teachers Speak Out on Assessment Practices

A 1997 statewide survey of Michigan teachers, administrators, and parents about assessment practices revealed that all 3 groups held similar views about what constitutes appropriate assessment in the early years, and they put little faith in test scores. This study reports on follow-up interviews aimed at determining the types, frequency, and utility of assessment techniques used by classroom teachers. Specifically, this study focused on the types of assessment techniques used by a sample of elementary teachers, including how often they use paper-and-pencil tests, how often they write observation notes and what they do with the notes, whether they use children's portfolios as assessment, and whether their teaching is influenced by mandated tests. Study findings revealed that paper and pencil tests were regularly used by teachers in grades 3 and 4 (92%), and rarely or occasionally used by the teachers below that level (16% rarely and 20% occasionally). Seventy-three percent of the early level teachers and 76% of the teachers in grade 3 and 4 used observation for summative rather than formative analysis. Teachers in both groups used checklists frequently, primarily for summative purposes. Portfolios, like other assessment tools, are used primarily for summative rather than formative purposes.     

Assessing the comparability of teacher-related constructs in TIMSS 2015 across 46 education systems: an alignment optimization approach

Research related to the “teacher characteristics” dimension of teacher quality has proven inconclusive and weakly related to student success, and addressing the teaching contexts may be crucial for furthering this line of inquiry. International large-scale assessments are well positioned to undertake such questions due to their systematic sampling of students, schools, and education systems. However, researchers are frequently prohibited from answering such questions due to measurement invariance related issues. This study uses the traditional multiple group confirmatory factor analysis (MGCFA) and an alignment optimization method to examine measurement invariance in several constructs from the teacher questionnaires in the Trends in International Mathematics and Science Study (TIMSS) 2015 across 46 education systems. Constructs included mathematics teacher’s Job satisfaction, School emphasis on academic success, School condition and resources, Safe and orderly school, and teacher’s Self-efficacy. The MGCFA results show that just three constructs achieve invariance at the metric level. However, an alignment optimization method is applied, and results show that all five constructs fall within the threshold of acceptable measurement non-invariance. This study therefore presents an argument that they can be validly compared across education systems, and a subsequent comparison of latent factor means compares differences across the groups. Future research may utilize the estimated factor means from the aligned models in order to further investigate the role of teacher characteristics and contexts in student outcomes.

     

#5: Non-Supine (e.g., Upright or Side-Lying) Positions for Birth

In this position paper—one of six care practice papers published by Lamaze International and reprinted here with permission—the benefit of non-supine positions for birth is discussed and presented as an evidence-based practice that helps promote, protect, and support normal birth. The paper is written for childbearing women and their families. Upright and gravity-neutral positions facilitate rotation and descent of the baby and result in reduced duration of second stage, a reduction in episiotomies, and fewer abnormal fetal heart rate patterns. The accompanying commentary—written by a leading proponent of maternity care—supports these benefits. Lamaze International recommends that laboring women not push until they feel an urge to do so, and that they choose positions for birth that are most comfortable for them.
