Two groups of pigeons were trained to perform symbolic delayed matching-to-sample at a 0-sec delay with sample stimuli that consisted of sequences of light flashes. The sequences varied in number but not time for one group (number group) and in time but not number for the other group (time group). When retention was tested at delays up to 10 sec in Experiment 1, a choose-small effect was found in the number group, and a choose-long effect was found in the time group. Transfer tests between number and time samples in Experiment 2 supported the hypothesis that pigeons were discriminating between the number of light flashes at the end of sample sequences in Experiment 1. It was concluded that pigeons in both the number and the time groups were discriminating between number of flashes and that the apparent choose-long effect was actually a choose-small effect. The implications of these findings for the mode-control model of counting and timing (Meck & Church, 1983) were discussed. 相似文献

Research indicates that preservice teacher (PT) education programs can positively impact perceptions of scientific probeware use in K-8 environments. Despite the potential of probeware to improve science instruction and student engagement, its use in elementary education has been limited. Sixty-seven PT enrolled across three sections of an elementary science methods course participated in a mixed-methods study through which they utilized probeware in a thematic experience on ocean acidification. One-way repeated measures ANOVA of pre and post survey data measuring subscales of utility, ability, and intent to use probeware demonstrated a statistically significant increase with medium to large effect sizes for all subscales across all sections \( \left(p<0.01,\kern0.5em {\eta}_p^2=0.384;\kern0.5em p<0.001,\kern0.5em {\eta}_p^2=0.517;\kern0.0em p<0.001,\kern0.0em {\eta}_p^2=0.214\right) \). Analysis of reflective journals revealed over 60% felt the multiple capabilities (notably graphing) of probeware make it a useful classroom tool, and almost one-half believed that its use makes science more enjoyable and engaging. Mapping of the unitized data from the journals on the Next Generation Science Standards suggested that probeware use especially engages learners in planning and carrying out investigations and in analyzing and interpreting data. Journals also revealed that despite PT having prior experience with probeware in science courses, its use in their future elementary classroom is conditional on having a positive experience with probeware in a science methods course. Further, embedding a probeware experience in a unit on ocean acidification provides PT with strategies for addressing climate change and engaging in argument from evidence. 相似文献

A common suggestion made in the psychometric literature for fixed‐length classification tests is that one should design tests so that they have maximum information at the cut score. Designing tests in this way is believed to maximize the classification accuracy and consistency of the assessment. This article uses simulated examples to illustrate that one can obtain higher classification accuracy and consistency by designing tests that have maximum test information at locations other than at the cut score. We show that the location where one should maximize the test information is dependent on the length of the test, the mean of the ability distribution in comparison to the cut score, and, to a lesser degree, whether or not one wants to optimize classification accuracy or consistency. Analyses also suggested that the differences in classification performance between designing tests optimally versus maximizing information at the cut score tended to be greatest when tests were short and the mean of ability distribution was further away from the cut score. Larger differences were also found in the simulated examples that used the 3PL model compared to the examples that used the Rasch model. 相似文献

Driven largely by calls for accountability, the use of large‐scale testing is expanding in terms of the number and purposes of testing programmes. At the same time, financial constraints have resulted in attempts to reduce the lengths of such examinations. An examination of the 1994/1995 and 1995/1996 British Columbia Scholarship programme illustrates that differential and unanticipated differences can occur when such changes to the testing programme are made. The removal of a portion of the constructed‐response (CR) and written tasks (WT) items used to identify scholarship recipients resulted in differences in scholarship scores and the identification of scholarship recipients. Further, the differences were found to affect subgroups of students differentially. While there were no differences attributed to gender, higher difference rates were associated with course area (humanities vs. science) or examination session (January vs. June). The results illustrate the complex and contextual impact of changes to examination programmes and the potential consequences of such changes. Test developers and users must make more of an effort to examine the consequences of examination programmes and planned changes upon the students and others who may be affected by the results. 相似文献

The effects of controversy and concurrence seeking and participation is age-homogeneous and age-heterogeneous cooperative learning groups were compared on achievement, achievement motivation, perspective-taking accuracy, and interpersonal attraction. In addition, the interaction among students within the cooperative learning groups was observed. One-hundred-twelve 4th-, 5th-, and 6th-grade students were assigned to conditions on a stratified random basis controlling for age, sex, reading ability, and homerooms. In all conditions, students studied two controversial issues with materials representing both pro and con views. In the controversy condition each small group was divided into two halves representing the pro and con sides. In the concurrence-seeking condition each small group studied pro and con materials on alternating days and were told to learn the material without arguing or disagreeing with one another. In the multi-age conditions 4th-, 5th, and 6th-graders were placed in the same learning groups, while in the single-age conditions students were placed in small groups with peers of the same age. The results indicate that controversy promoted higher achievement, greater achievement motivation, and more accurate perspective taking than did concurrence seeking. Multi-age learning groups had greater achievement motivation than did the single-age groups. 相似文献

Differentiated instruction is a proactive teaching model and philosophy with demonstrated potential to cater for diverse learners and create inclusive classrooms. There is little research, however, into the implementation of this approach in the senior secondary classroom. Teachers’ implementation of differentiated instruction has been shown to be linked to teacher attitudes and self-efficacy in other settings. This study investigated the impact of teachers’ self-efficacy and attitudes towards the implementation of differentiated instruction in the senior secondary context across two Australian states with a total of five participating teachers. The A (Affective) B (Behaviour) C (Cognitive) model was employed to define teacher attitudes from interviews concerning differentiated instruction. Findings indicated that teacher knowledge was a major factor influencing differentiation, in addition to attitude and self-efficacy. The discourse analysis demonstrated that teachers held a greater knowledge of differentiation strategies than the concepts that underpin the differentiated instruction framework. Additionally, time constraints and feelings of failure in implementing differentiation strategies impacted teacher attitudes. Teacher knowledge, attitude and self-efficacy were interrelated and impacted on teachers’ implementation of differentiated instruction in the senior secondary classroom. Implications for professional development to address student needs through differentiated instruction in the inclusive senior secondary classroom teacher are discussed. 相似文献

This study details a program evaluation of the PREPa RE School Crisis Prevention and Intervention Training Curriculum (PREPa RE), conducted in the United States and Canada between 2009 and 2011. Significant improvements in crisis prevention and intervention attitudes and knowledge were shown among 875 Crisis Prevention and Preparedness workshop (Workshop 1) participants and 1,422 Crisis Intervention and Recovery workshop (Workshop 2) participants on matched pre‐tests and post‐tests. Results indicated high participant satisfaction for both Workshop 1 and Workshop 2. A qualitative analysis of workshop evaluation comments indicated strengths regarding workshop aims, materials, and activities, as well as suggestions for improvement, such as utilizing more active learning components. The use of these findings in the PREPa RE curriculum revision is discussed. 相似文献

This article examines the influence of a practicum teaching experience on two pre-service science teachers. The research is focused on examining a practicum in a secondary science department that actively promotes the teaching and learning of science as inquiry. We investigated the process through which the pre-service science teachers integrated their practical knowledge, and examined this in the context of the quantified reformed instruction they enacted. Using a mixed methods design, we have quantified these pre-service science teachers’ practice using the Reformed Teaching Observation Protocol (Piburn et al. 2000), in concert with a narrative methodology drawn from in-depth interviews. Our analysis of the data indicates two important conclusions. The first is the importance of a consistently reformed image of science education being presented and practiced by both science teacher educators and cooperating teachers. The second is the recognition that a consistently reformed image may not be sufficient, of itself, to challenge pre-service teachers’ views of science education. Pre-service teachers appear to be heavily influenced by their biographies and own science education. Consequently, it appears the extent to which a pre-service teacher identifies problems of teaching and learning, and then works toward possible resolution, influences their progress in shaping reformed views of science education. 相似文献
