Anatomical Sciences Education Vol. 5, Issue 3, 2012 Cover Image

Medical students at the Schulich School of Medicine and Dentistry at The University of Western Ontario in London, Ontario, Canada, learn clinical facts about the hepatobiliary system as transplant surgeon Dr. Vivian McAlister (at the far right) demonstrates Whipple's procedure in the anatomy laboratory. In this issue of ASE, Ullah and colleagues describe an extracurricular student initiative known as the Surgically Oriented Anatomy Program (SOAP), which aims to deliver anatomy teaching from a surgical perspective through the philosophy of “education through recreation”.     

College Students’ Conceptions of Stem Cells, Stem Cell Research, and Cloning

In this study, we examined 96 undergraduate non-science majors’ conceptions of stem cells, stem cell research, and cloning. This study was performed at a large, Midwest, research extensive university. Participants in the study were asked to answer 23 questions relating to stem cells, stem cell research, and cloning in an on-line assessment before and after instruction. Two goals of the instruction were to: (1) help students construct accurate scientific ideas, and (2) enhance their reasoning about socioscientific issues. The course structure included interactive lectures, case discussions, hands-on activities, and independent projects. Overall, students’ understandings of stem cells, stem cell research, and cloning increased from pre-test to post-test. For example, on the post-test, students gained knowledge concerning the age of an organism related to the type of stem cell it possesses. However, we found that some incorrect ideas that were evident on the pre-test persisted after instruction. For example, before and after instruction several students maintained the idea that stem cells can currently be used to produce organs.     

Defining the Difference: Comparing Integrated and Traditional Single-Subject Lessons

Early childhood curricula should be authentic and child-centered, however, many teachers still rely on direct instruction lessons. To better define how an integrated curriculum meets the needs of students, this study examined teacher talk and actions during instructional activities with first and second graders under two conditions: (1) subject-integrated social studies lessons of an integrated curriculum unit (experimental condition); and (2) single subject-focused mathematics lessons of a traditional separate subject curriculum (control condition). The mixed-methods study sought to define and compare characteristics of both curriculum approaches. Fourteen hours of observations were collected in each setting. In the integrated curriculum setting, the teacher was a facilitator of teamwork, offering choices, and giving praise; students made choices, decisions, and worked collaboratively. In the traditional setting, the teacher delivered direct instruction and controlled behavior; students followed directions, recalled knowledge, and worked individually. Less teacher energy was expended for behavior management in the integrated curriculum setting, indicating intrinsic motivation of students. Implementation of integrated curricula is recommended because of the student-centered focus that results in greater motivation, ownership, and teamwork, along with deeper knowledge connections. Because many factors hinder implementation, teachers need support when first teaching with this approach.     

Promoting Community in Early Childhood Programs: A Comparison of Two Programs

Every interaction within an early childhood program either promotes community or disrupts it. Therefore, excellent early childhood programs have in place a process that pulls the energies and abilities of all the members of the school community together so that everyone—children, educators, parents, and community members—develop well. In particular, healthy interactions between educators and families create the necessary conditions for the early childhood programs: (1) to impact the lifepaths of the families; and, in turn, (2) to engage the families in the work of improving the early childhood programs. In this article, research on the Jewish Early Childhood Education Initiative (JECEI) is presented. JECEI was selected for study because JECEI early childhood programs are characterized by healthy relationships, the capacity to successfully promote children’s learning and development, and the engagement of families in the work of school improvement.     

Enhancing Student Learning in Food Engineering Using Computational Fluid Dynamics Simulations

Abstract: The current generation of students coming into food science and engineering programs is very visually oriented from their early experiences. To increase their interest in learning, new and visually appealing teaching materials need to be developed. Two diverse groups of students may be identified based on their math skills. Food science students tend to find it difficult to use mathematics as a problem‐solving tool for food engineering problems. Food engineering students, on the other hand, should be challenged to use emerging mathematical tools to develop their problem‐solving skills. Therefore, the approach of this project involved the development of a curriculum to train undergraduate food engineers in the effective use of computational fluid dynamics (CFD) software to solve food engineering problems by engaging them in the creation of food engineering teaching tools. These CFD outputs were then used as innovative teaching tools for the food science students. In this paper, this concept will be illustrated by unsteady‐state heat transfer and fluid flow problems. To evaluate the efficiency of the teaching materials developed, a student focus group was asked to answer the same quiz following a conventional and CFD output aided teaching session. The assessment result showed an improved understanding of the subject after the CFD teaching session. These visual aids were excellent tools to illustrate the validity of the formulas presented in class. In addition, the new visual materials enabled a better understanding of the relationships among different process parameters. In general, this helped the food science students better appreciate the food engineering concepts that govern food processing operations.     

Effect of outcome valence on positive and negative patterning in human causal reasoning

The importance of configural cues and whether a situation involves beneficent or maleficent outcomes was investigated in two experiments on human causal reasoning, based on experienced causal information. Participants learned positive and negative patterning discriminations involving either beneficent or maleficent outcomes in a health-reasoning task and in a social-reasoning task. With maleficent outcomes, positive patterning was consistently easier to learn than negative patterning, a positive patterning advantage that is predicted by current associative theories and commonly taken as evidence for configural cues. However, with beneficent outcomes, the two discrimination tasks were not significantly different in ease of learning, a result not predicted by current theories. The reliable positive patterning effect found with maleficent outcomes broadens the range of conditions in which the effect can be shown in causal reasoning. The novel effect of outcome valence poses an interesting theoretical challenge for attempts to account for the relation between learning about individual cues and combinations of those cues.     

Collaboration modality, cognitive load, and science inquiry learning in virtual inquiry environments

Educational multi-user virtual environments (MUVEs) have been shown to be effective platforms for situated science inquiry curricula. While researchers find MUVEs to be supportive of collaborative scientific inquiry processes, the complex mix of multi-modal messages present in MUVEs can lead to cognitive overload, with learners unable to effectively process the rich information encountered in virtual space. In this study, we investigated the effect of communication modality on cognitive load and science inquiry learning in students completing a science inquiry curriculum in an educational MUVE. Seventy-eight undergraduate education majors from a large southwestern university participated in this control-treatment study. Significant positive results were found for reducing cognitive load for participants communicating through voice-based chat, although this reduction was not found to influence learning outcomes. We conclude that use of voice-based communication can successfully reduce cognitive load in MUVE-based inquiry curricula.     

Attachment Styles,Social Skills,and Depression in College Women

Attachment styles, social skills, and depression were studied in 93 college women using the Relationship Questionnaire (K. Bartholomew & L. M. Horowitz, 1991), the Beck Depression Inventory‐II (A.T. Beck, R.A. Steer, & G. K. Brown, 1996), and the Interpersonal Competence Questionnaire (D. Buhrmester, W. Furman, M.T. Wittenberg, & H.T. Reis, 1988). The self and other attachment models and the social skills of negative assertion, self‐disclosure, and conflict management all correlated with depression. Conflict management partially mediated the relationship between attachment self‐model and depression. Implications for counseling are discussed.     

Relative Age Effects are a developmental problem in tennis: but not necessarily when you’re left‐handed!

Relative Age Effects (RAEs), describing attainment inequalities as a result of interactions between biological age and age‐grouping procedures, have been demonstrated across many sports contexts. This study examined whether an additional individual characteristic (i.e., handedness) mediated RAEs in tennis. Relative age and handedness distributions of 1027 male professional tennis players ranked in the year‐end ATP Top 500 for 2000–2006 were analyzed. Relatively older players, born in the first two quartiles, were over‐represented for right‐handed players (86.56%), whereas no RAEs were found for left‐handers (13.44%). Findings seem to suggest that left‐handers in tennis gain advantages that circumvent the RAE problem.
