Peer and self-assessment applied to oral presentations from a multidisciplinary perspective

This article analyses the use of peer and self-assessment in oral presentations as complementary tools to assessment by the professor. The analysis is based on a study conducted at the University of Girona (Spain) in seven different degree subjects and fields of knowledge. We designed and implemented two instruments to measure students’ peer and self-assessment, and a rubric to guide the assessment process. Results were compared with the marks awarded by the professor. In contrast with studies by other authors, which show a high correlation between these different assessment systems, our study revealed significant deviations. Applying peer and self-assessment to oral presentation activities also demonstrates their formative value above and beyond their summative usefulness.     

MIND IS PRIMARILY A VERB: AN EXAMINATION OF MISTAKEN SIMILARITIES BETWEEN JOHN DEWEY AND HERBERT SPENCER

A bstract .  In educational scholarship, a number of comparisons have been made between the work of John Dewey and Herbert Spencer, many claiming that Spencer's influence is unmistakable in Dewey's theories or even that Dewey is derivative of Spencer. However, one must look beyond the surface similarities of Dewey and Spencer and recognize the drastically divergent views that each held on those very foundational notions upon which each built his educational program. In this essay, Robin Zebrowksi examines the theories of evolution, the directionality of organism and environment interaction, the agency of the individual, and the conceptualizations of progress in the respective works of Dewey and Spencer. Their underlying beliefs about the world and how it operates show that their philosophies cannot be reconciled. The educational theories that follow from these discrepancies, Zebrowski concludes, have incompatible and distinct implications for the classroom.     

Musicality in the Language of Picture Books

The authors of picture books who write especially melodic language are doing more than simply offering up work that is pleasing to the ear. They are accessing more of the whole child. In this article five picture books will be discussed for their musical attributes: Now One Foot, Now the Other, by Tomie dePaola, The Cat in the Hat, by Dr. Seuss, Knuffle Bunny, by Mo Willems, Mirandy and Brother Wind, by Patricia C. McKissack, and Click Clack Moo, by Doreen Cronin. Drawing on the observations of scientists, educators, and composers, I will discuss what an extraordinary aid a picture book with musical sounding language can be in the nurturing and development of the young child’s intellect, emotional life, and social skills.     

The influence of reading unit size on the development of Stroop interference in early word decoding

The purpose of the experiments was to determine the automatic use of large or small word reading units in young readers in the absence of word decoding strategies. Picture-word Stroop interference was examined from four types of conflicting labels: (a) words containing both highly predictable grapheme–phoneme correspondence (GPC) units and highly consistent rime units (henceforth, Hi-GPC + Hi-Rime); (b) words with highly predictable GPC units and less consistent rime units (Hi-GPC + Lo-Rime); (c) words with low predictability GPC units and highly consistent rime units (Low GPC + High Rime); (d) nonwords that contained both highly predictable GPC and highly consistent rime units. Naming time for pictures containing these labels was compared against that for pictures with random letter strings or no labels. In Experiment 1, Stroop interference was examined in first, second, and third grade children to determine whether there was developmental change in the presence of rime or GPC interference. In Experiment 2, Stroop interference was examined as a function of relative reading skill in first grade children. In Experiment 3, Stroop interference in adults was compared to the use of rime or GPC pronunciation strategies for nonword reading. In all experiments, Stroop interference in picture naming was longer for pictures with highly predictable GPC unit labels than less predictable GPC unit labels. However, in Experiment 3, even though adults showed interference from predictable GPC units in the Stroop task, they always preferred rime pronunciation for ambiguous nonwords in the nonword reading task. It is argued that the current experiments provide evidence for a flexible units model. The results of this study were presented at the Cognitive Development Society meeting, November 2001, Virginia Beach, VA, and the American Educational Research Association meeting, April 2004, San Diego, California.     

Going to Prison: The Effect of a Prison Tour on Students’ Attitudes Toward Punitiveness

The pedagogical approaches of a criminal justice education affect the attitudes and perceptions of those most likely to develop and administer criminal justice policies in the future. This study examines the effect of a prison tour on students’ understanding of prison and attitudes about punishment. Undergraduate criminal justice students were given a survey to assess their attitudes about prisons, prisoners, and alternative sanctions before and after a field trip to the Southern Ohio Correctional Facility. Post-survey responses showed changes in students’ perceptions regarding punitiveness, prisons, prisoners, and rehabilitation. We discuss this finding within the framework of the contact hypothesis, and we recommend including this type of first-hand exposure as part of a criminal justice curriculum.     

Predicting relevance based on assessor disagreement: analysis and practical applications for search evaluation

Evaluation of search engines relies on assessments of search results for selected test queries, from which we would ideally like to draw conclusions in terms of relevance of the results for general (e.g., future, unknown) users. In practice however, most evaluation scenarios only allow us to conclusively determine the relevance towards the particular assessor that provided the judgments. A factor that cannot be ignored when extending conclusions made from assessors towards users, is the possible disagreement on relevance, assuming that a single gold truth label does not exist. This paper presents and analyzes the predicted relevance model (PRM), which allows predicting a particular result’s relevance for a random user, based on an observed assessment and knowledge on the average disagreement between assessors. With the PRM, existing evaluation metrics designed to measure binary assessor relevance, can be transformed into more robust and effectively graded measures that evaluate relevance towards a random user. It also leads to a principled way of quantifying multiple graded or categorical relevance levels for use as gains in established graded relevance measures, such as normalized discounted cumulative gain, which nowadays often use heuristic and data-independent gain values. Given a set of test topics with graded relevance judgments, the PRM allows evaluating systems on different scenarios, such as their capability of retrieving top results, or how well they are able to filter out non-relevant ones. Its use in actual evaluation scenarios is illustrated on several information retrieval test collections.     

University Choice: What Influences the Decisions of Academically Successful Post‐16 Students?

The questionnaire survey reported in this paper is part of an ongoing evaluation of the effect of a bursary scheme on recruitment to Cambridge University. It sought to identify factors that encouraged or discouraged highly successful A Level students from applying to Cambridge. Findings reveal three main dimensions associated with the decision to apply to Cambridge, the nature of the courses, the prestige of the university and anxiety about the application process combined with fear of failure. Further analyses showed that there were complex interactions between these three dimensions which governed the decision to apply to Cambridge. These findings are relevant to other prestigious universities. The availability of a bursary did appear to influence the decisions of those who were eligible, but its influence was not as great as some of the other factors.
