The purpose of this project was to develop a valid and reliable science process skill test for middle and high school students. Multiple-choice items were generated for each of five objectives. Following pilot testing and revision, the test was administered to middle and high school students in the northeastern United States. The 36-item test can be completed in a normal class period. Results yielded a mean score of 19.14 and a total test reliability of 0.86. Mean difficulty and discrimination indices were 0.53 and 0.35, respectively. Split-test correlations coefficients between TIPS II and the original TIPS items were 0.86 and 0.90. TIPS II provides another reliable instrument for measuring process skill achievement. Additionally, it increases the available item pool for measuring these skills. 相似文献

Teacher evaluation instruments frequently fail to support teacher growth and improvement—particularly in critical constructs surrounding pedagogical content knowledge that promote student growth and achievement. The current study details the development and validation of the Teacher Intentionality of Practice Scale (TIPS), an observational protocol designed to measure intentional teaching practices and provide support for teacher growth over time. Findings suggest that TIPS provides a valid and highly reliable research-based teacher observational instrument that also serves as a professional development model to help scaffold the growth and improvement of K-12 educators. This paper details the theoretical foundations of TIPS, reports reliability and validity measures (including both Exploratory and Confirmatory Factor Analyses), and discusses applications and implications of TIPS for teacher evaluation and professional development. 相似文献

Effectiveness of microcomputer simulations in stimulating environmental problem solving by community college students 总被引：1，自引：0，他引：1
This study examined the impact of microcomputer simulations on environmental problem solving by community college students. A subordinate question was also addressed: Was the test instrument, which was used to assess the outcome of the treatment, biased by reading ability? The quasiexperimental design used two intact groups of community college students and parallels an earlier study by Rivers and Vockell (1987). The experimental group was assigned three simulation modules that focused on lake pollution analysis, wastewater quality management, and population dynamics. The comparison group was not exposed to any simulations, and served as a quasicontrol to identify possible Hawthorne effects. Effectiveness was assessed by the Test of Integrated Process Skills (TIPS I and II). Statistical analyses were done with t tests, Pearson product-moment correlation coefficients, and reliability coefficients. The experimental group showed a highly significant improvement in problem-solving skills after treatment, t(33) = 4.42, p < 0.001. Subtest mean gain scores supported the hierarchical relationships among cognitive modes for transitional operational reasoners as reported by Yap and Yeany (1988). An analysis of the correlation between the TIPS I and Nelson-Denny reading test scores indicated that the TIPS did not have a reading-level bias for the subjects in this study. Informal and anecdotal observations described improvements in other problem-solving skills which were not measured by the TIPS. 相似文献

The need for a redefinition of first year experience in higher education is advocated with the aid of two models, which, although focused on a sample of Australian pre-service teaching students, is proposed as generalisable across the first year. Introduction to the mores of higher education is generally supported by teaching institutions during Orientation days and into the first few weeks of study on the assumption that students are then prepared for academic study. Institutions have invested significantly in providing a range of resources and services to support this process but their effectiveness relies on their timely and appropriate use by students. It is proposed that first year students' transition be identified as the FYST, a unique and important experience and the first of a series of transitions that occur throughout tertiary study. It is also argued that student engagement should be explicitly linked to critical points in the academic programme. Student teacher focus group feedback suggests that Timely, Individualised, and Prioritised Survival [TIPS] support may be key to aiding students' transition to higher education and valuable to student retention. 相似文献

Background: Hepatic hydrothorax is defined as a significant pleural effusion in patients with liver cirrhosis and without underlying cardiopulmonary diseases. Treatment of hepatic hydrothorax remains a challenge at present. Methods: Herein we share our experiences in the treatment of 12 patients with hepatic hydrothorax by video-assisted thoracoscopic surgery (VATS).Repair of the diaphragmatic defects, or pleurodesis by focal pleureetomy, talc spray, mechanical abrasion, electro-cauterization or injection was administered intraoperatively, and tetracycline intrapleural injection was used postoperatively for patients with prolonged (＞7 d) high-output (＞300 ml/d) pleural effusion. Results: Out of the 12 patients, 8 (67%) had uneventful postoperative course and did not require tube for drainage more than 3 months after discharge. In 4 (33%) patients the pleural effusion still recurred after discharge due to end-stage cirrhosis with massive ascites. Conclusion: We conclude that the repair of the diaphragrnatic defect and pleurodesis through VATS could be an alternative of transjugular intrahepatic portal systemic shunt (TIPS) or a bridge to liver transplantation for patients with refractory hepatic hydrothorax. Pleurodesis with electrocauterization can be an alternative therapy if talc is unavailable. 相似文献

The ability to plan and execute projects is a fundamental skill required among managers and business school graduates. In the opening phase of a project, the project team makes decisions about the relative priority of project time, cost, and performance objectives, oftentimes without complete information about customer and stakeholder requirements. Existing project management curriculum assists in developing skills to decide among these priorities in the abstract through paradigms such as the time–cost–performance triangle, with limited attention to the improvement of skills required to develop solutions to these trade-offs, particularly in uncertain and ambiguous project environments. Further, there is often an underlying bias in project teams toward consideration of the project task and project deliverables and reduced attention to time and cost objectives. This study demonstrates the benefits of a balanced approach to setting project time, cost, and performance objectives using a goal-based simulation exercise entitled "The Bridge to Project Leadership." Results for 124 project teams illustrate the tendency to ignore this balanced approach, resulting in reduced project performance, even among experienced project managers. 相似文献

The article is based on a research and development work project (R&D project) conducted in a Norwegian lower secondary school. The purpose of the text is to describe the researchers’ and teachers’ roles during the initial phase of such a project, and what this phase and the close cooperation between the researcher and teachers mean for the progress of the project. The reader will see how the participating teachers modify their attitudes to the project throughout the start-up phase. This phase is outlined by means of empirical data. The study shows how such a project challenges the researchers’ communicative, social and knowledge competence. Furthermore, teachers have to see the need for development and willingly participate in developmental processes, listening to and using researchers as resource persons, if a start-up phase is to be successful for subsequent development in the project. 相似文献
