Gauging the effectiveness of specific teaching strategies remains a major topic of interest in science education. Inquiry teaching among others has been supported by extensive research and recommended by the National Science Education Standards. However, most of the empirical evidence in support was collected in research settings rather than in normal school environments. Propensity score analysis was performed within the marginal mean weighting through stratification (MMW-S) approach to examine the effects of the level of openness of inquiry teaching on student science achievement and attitudes with the Programme for International Student Assessment (PISA) 2006 data. Weighting subjects on MMW-S weight successfully balanced all treatment groups on all selected covariates. Significant effects were identified on both cognitive and attitudinal outcomes. For student science achievement, the highest score was achieved at Level 2 inquiry teaching, that is, students conduct activities and draw conclusions from data. For student science attitudes, higher level of inquiry teaching resulted in higher scores. The said conclusions were generally held in most PISA 2006 participating countries when the analysis was performed in each country separately. 相似文献

Assessment data must be valid for the purpose for which educators use them. Establishing evidence of validity is an ongoing process that must be shared by test developers and test users. This study examined the predictive validity and the diagnostic accuracy of universal screening measures in reading. Scores on three different universal screening tools were compared for nearly 500 second‐ and third‐grade students attending four public schools in a large urban district. Hierarchical regression and receiver operating characteristic curves were used to examine the criterion‐related validity and diagnostic accuracy of students’ oral reading fluency (ORF), Fountas and Pinnell Benchmark Assessment System (BAS) scores, and fall scores from the Measures of Academic Progress for reading (MAP). Results indicated that a combination of all three measures accounted for 65% of the variance in spring MAP scores, whereas a reduced model of ORF and MAP scores predicted 60%. ORF and BAS scores did not meet standards for diagnostic accuracy. Combining the measures improved diagnostic accuracy, depending on how criterion scores were calculated. Implications for practice and future research are discussed. 相似文献

Recently, the nature of science (NOS) has become recognized as an important element within the K-12 science curriculum. Despite differences in the ultimate lists of recommended aspects, a consensus is emerging on what specific NOS elements should be the focus of science instruction and inform textbook writers and curriculum developers. In this article, we suggest a contextualized, explicit approach addressing one core NOS aspect: the human aspects of science that include the domains of creativity, social influences and subjectivity. To illustrate these ideas, we have focused on Charles Darwin, a scientist whose life, work and thought processes were particularly well recorded at the time and analyzed by scholars in the succeeding years. Historical facts are discussed and linked to core NOS ideas. Creativity is illustrated through the analogies between the struggle for existence in human societies and in nature, between artificial and natural selection, and between the division of labor in human societies and in nature. Social influences are represented by Darwin’s aversion of criticism of various kinds and by his response to the methodological requirements of the science of that time. Finally, subjectivity is discussed through Darwin’s development of a unique but incorrect source for the origin of variations within species. 相似文献

The two concepts law and theory are among the most important elements of the nature of science. They represent both the tools and products of science itself. Unfortunately, the variable meanings and use of these terms in general discourse and in other school disciplines results in much confusion with respect to their proper application in a science context. The project included the design of a six-part model definition for law and theory based on a review of the literature of the philosophy of science with special reference to biology. These model definitions were then compared with those provided in a range of U.S. secondary school biology textbooks. The majority of all current major U.S. secondary school biology texts were reviewed and analyzed with respect to how the concepts of law and theory were defined and applied, in an attempt to determine whether students and teachers using such texts would gain an accurate impression of these terms and the distinction between them. This study focuses on biology instruction since a life science course is completed as a graduation requirement by virtually all U.S. high school students and as such serves as a widely shared educational experience across the nation. The term law is rarely defined in any text but various laws such as those found in genetics are frequently included as examples. The term theory is frequently defined but with a wide range of completeness of the definitions. Only rarely are theories in biology included as examples. 相似文献

Response to Intervention (RtI) is being implemented as a new initiative in PK‐12 schools with increasing frequency. However, the model must be sustained at the school level, which is potentially difficult due to a number of challenges brought about by systems change. This article applied the Stokes and Baer (1977) framework for programming for generalization and maintenance of behavior change to suggest specific activities in which schools could engage to better ensure RtI sustainability. We specifically discussed ways to (1) introduce to natural maintaining contingencies, (2) train with sufficient exemplars, (3) train loosely, (4) program common stimuli, (5) mediate generalization, and (6) train to generalize. Directions for future research are included. 相似文献
