Students’ Reflections on Implementation of Group Investigation in Korean Secondary Science Classrooms

Student reflective ideas were examined with respect to Group Investigation (GI), which was employed in 11^th grade Korean earth science classrooms. A modified GI method was implemented during the course of an action research effort consisting of two yearlong projects. Students’ writings, which had been produced twice a year, were analyzed to reveal their reflections concerning the GI method. The students were positive about how GI altered the ways their learning occurred in the classrooms. They also reported several positive learning outcomes resulting from the GI implementation. However, there were some students who considered the GI method inappropriate for them. At times, students had difficulties and experienced problems arising from implementing GI. Implications for use of cooperative inquiry learning methods in science classrooms are elaborated on and discussed.     

Longitudinal outcome effects of non-at-risk and at-risk transition first-grade samples: A follow-up study and further analysis

Fourth-grade follow-up achievement outcome data of placed and nonplaced transition extra-year school readiness samples indicate a nonsignificant standardized score difference, as noted in the second-grade findings. New analysis of correlation data indicates that within-sample age distribution shows a positive correlation with standardized achievement test scores in a study sample of non-at-risk students nonretained or recommended for retention. This age-achievement correlation is strong in kindergarten, with decreased effects by second and fourth grade. Four study samples of at-risk students (students retained in a transition extra-year school readiness program, students recommended and eligible for such placement but not placed, students retained in kindergarten through second grade, and students held out of school prior to kindergarten) reflect moderate inverse (negative) correlations between age and achievement test scores, with increasing inverse effects in fourth grade. Effect analysis and implications are discussed. © 1996 John Wiley & Sons, Inc.     

The influence of reputation information on the assessment of undergraduate student work

The present study employed an experimental design to examine the influence of knowledge of a student’s previous performance and the general quality of their writing style on the assessment of undergraduate student work. Fifteen sport and exercise physiology academics were asked to mark and give feedback on two final year undergraduate student essays. The first student essay that participants marked was a control essay. The second essay was the target essay. Participants read one of three student reputation profiles (positive, negative or neutral) prior to marking this essay. Kruskal–Wallis tests for difference indicated that the marks awarded to each essay did not significantly differ between the three student reputation conditions. Thematic analysis of the target essay also revealed no apparent differences in the way in which feedback was presented across the three student reputation profiles. It was therefore concluded that non-anonymous marking did not induce marker bias in this instance.     

THE BULLYING DYNAMIC: PREVALENCE OF INVOLVEMENT AMONG A LARGE‐SCALE SAMPLE OF MIDDLE AND HIGH SCHOOL YOUTH WITH AND WITHOUT DISABILITIES

Bullying has been the topic of much debate and empirical investigations over the past decade. Contemporary literature contends that students with disabilities may be overrepresented within the bullying dynamic as both perpetrators and victims. Unfortunately, prevalence rates associated with the representation of students with disabilities is limited due to measurement, disability status identification, and definition issues. The present study attempted to address these issues by assessing the prevalence rates of specific subgroups of students with disabilities in a large‐scale cross‐sectional study with 13,325 students without disabilities and 1,183 students with disabilities in Grades 6 through 12. Results suggest that overall, students with disabilities reported proportionally higher rates of bullying, fighting, relational aggression, victimization, online victimization, and relational victimization than did their peers without disabilities. These findings suggest that schools must begin to establish targeted interventions to support skill development based on characteristics associated with specific disability identification.     

Conditional inference and advanced mathematical study

Many mathematicians and curriculum bodies have argued in favour of the theory of formal discipline: that studying advanced mathematics develops one’s ability to reason logically. In this paper we explore this view by directly comparing the inferences drawn from abstract conditional statements by advanced mathematics students and well-educated arts students. The mathematics students in the study were found to endorse fewer invalid conditional inferences than the arts students, but they did not endorse significantly more valid inferences. We establish that both groups tended to endorse more inferences which led to negated conclusions than inferences which led to affirmative conclusions (a phenomenon known as the negative conclusion effect). In contrast, however, we demonstrate that, unlike the arts students, the mathematics students did not exhibit the affirmative premise effect: the tendency to endorse more inferences with affirmative premises than with negated premises. We speculate that this latter result may be due to an increased ability for successful mathematics students to be able to ‘see through’ opaque representations. Overall, our data are consistent with a version of the formal discipline view. However, there are important caveats; in particular, we demonstrate that there is no simplistic relationship between the study of advanced mathematics and conditional inference behaviour.

Human causality judgments and response rates on DRL and DRH schedules of reinforcement

The effect of various relationships between a response (an investment made in the context of a game) and an outcome (a return on the investment) on judgments of the causal effectiveness of the response was examined. In Experiment 1, response rates and causal judgments were higher for a differential-reinforcement-of-high-rate (DRH) schedule relative to a variable-ratio (VR) schedule with the same probability of outcome following a response. Response rates were also higher for a DRH than for a variable-interval schedule matched for reinforcement rate. In Experiment 2, response rates and causal judgments were lower for a differential-reinforcement-of-low-rate schedule relative to a VR schedule with the same probability of outcome following a response. These results corroborate the view that schedules are a determinant of both response rates and causal judgments, and that few current theories of causal judgment explicitly predict this pattern of results.     

Silicon Valley versus Silicon Glen: the impact of computers upon teaching and learning: a comparative study

Drawing on data from a major survey on the impact of information technology initiatives on Scottish schools, we assess the extent to which the outcomes resemble those that have already been reported by Larry Cuban in his study of schools in Silicon Valley. We find a large measure of agreement. Scottish teachers and school students mostly have access to computers in their homes and classrooms. The home computers appear to be frequently used. The classroom computers, however, are encountered by students only seldom and when students do use computers in the classroom the activity is often peripheral to the learning process, such as word processing of essays. We discuss some possible explanations for this state of affairs and suggest some implications for policy-making.     

Pedagogical Transformations of Science Content Knowledge in Korean Elementary Classrooms

While a solid understanding of science content knowledge is important in developing expertise in science teaching, it is not necessarily a sufficient condition to teach science effectively in elementary schools. Teachers need to have the ability to transform their knowledge into forms learnable by students. Based on this perspective, the current study explored how science content knowledge was pedagogically transformed in Korean elementary classrooms. Data sources included video-recorded science lessons of five elementary teachers in a metropolitan city of Korea. The analysis of the data revealed that the Korean teachers often engaged in transforming science content knowledge by means of different semiotic modes, including language, pictures, materials, actions, and their complex combinations. Further, their representations of scientific knowledge were in diverse forms, such as personifications, analogies, quiz questions, pictorial models, diagrams, animations, real-life examples, hand demonstrations, videos, flash tools, and songs-and-dances. Future research involving a wider range of participants, such as students, content specialists, and teachers with weak and strong content understanding, was suggested to confirm the findings of this study and find more various ways of pedagogical transformation of science subject matter knowledge.
