Evaluation of the Redesign of an Undergraduate Cell Biology Course

This article offers a case study of the evaluation of a redesigned and redeveloped laboratory-based cell biology course. The course was a compulsory element of the biology program, but the laboratory had become outdated and was inadequately equipped. With the support of a faculty-based teaching improvement project, the teaching team redesigned the course and re-equipped the laboratory, using a more learner-centered, constructivist approach. The focus of the article is on the project-supported evaluation of the redesign rather than the redesign per se. The evaluation involved aspects well beyond standard course assessments, including the gathering of self-reported data from the students concerning both the laboratory component and the technical skills associated with the course. The comparison of pre- and postdata gave valuable information to the teaching team on course design issues and skill acquisition. It is argued that the evaluation process was an effective use of the scarce resources of the teaching improvement project.     

Assessment of learning outcomes in Finnish vocational education and training

This article provides an outline and critical review of assessment, an evaluation of learning outcomes, in vocational education and training (VET) in Finland. Assessment of VET is formative, development-orientated and criteria-based. There are no national tests and information from vocational skills demonstrations is used instead. Assessment targets are individual and communal learning focusing on processes instead of reports. Interactive, multifaceted assessments and qualitative methods promote learning and are based on trust – not control. The developmental assessment of learning outcomes started as an experiment in 2002 and as a permanent system in 2007. The whole process has been included and still includes also many challenges of methods, which this article tries to open.

Caregiving and Social Support: A Twenty-first Century Challenge for College Students

This study adopted a caregiving perspective to analyze college students’ supportive relationships (N=266). With respect to the provision of care, female caregivers engaged in more difficult types of hands-on support than male caregivers, and data suggested that college caregivers are differently challenged by the life stage of the person for whom they provide care. With respect to students’ reception of social support, both main and interaction effects were found for sex, care giving status, and locus of control. Discussion focuses on the developmental nature of caregiving skills, social support reciprocity, and implications of these findings for public policy and human communication research.
