This longitudinal study examines the relationship between students' knowledge-in-use performance and their performance on third-party designed summative tests within a coherent and equitable learning environment. Focusing on third-grade students across three consecutive project-based learning (PBL) units aligned with the Next Generation Science Standards (NGSS), the study includes 1067 participants from 23 schools in a Great Lakes state. Two-level hierarchical linear modeling estimates the effects of post-unit assessments on end-of-year summative tests. Results indicate that post-unit assessment performances predict NGSS-aligned summative test performance. Students experiencing more PBL units demonstrate greater gains on the summative test, with predictions not favoring students from diverse backgrounds. This study underscores the importance of coherence, equity, and the PBL approach in promoting knowledge-in-use and science achievement. A systematically coherent PBL environment across multiple units facilitates the development of students' knowledge-in-use, highlighting the significance of designing science and engineering practices (SEPs) and crosscutting concepts coherently and progressively, with intentional revisitation of disciplinary core ideas (DCIs). The study also investigates how the PBL approach fosters equitable learning environments for diverse demographic groups, offering equitable opportunities through equity-oriented design. Contributions include a coherent assessment system that tracks and supports learning aligned with NGSS, emphasizing the predictive power of post-unit assessments, continuous monitoring and tracking. The implications of context similarity and optimal performance expectations within units are discussed. Findings inform educators, administrators, and policymakers about the benefits of NGSS-aligned PBL systems and the need for coherent and equitable learning and assessment systems supporting knowledge-in-use development and equitable opportunities for all learners.  相似文献

Though environmentally responsible behavior (ERB) has been a focus of many studies in the field of environmental education, very few scales have been developed to assess children’s ERB. In this regard, this article focuses on the development and validation of Children’s Responsible Environmental Behavior Scale (CREBS) and also reports the psychometric properties of this scale. The items in the CREBS were developed initially from the responses to four open-ended items by 229 fourth and fifth grade students. This initial form was pilot tested with 673 fourth and fifth graders and then subjected to exploratory factor analysis. Later, the revised version of the scale was administrated to 2412 fifth graders, and those results were subjected to confirmatory factor analysis and reliability analysis. CREBS consists of 23 items measured using a seven-point Likert-type scale, which have been organized into four sub-scales: political action (six items, α?=?.92); eco-management (six items, α?=?.70); consumer and economic action (five items, α?=?.70); and Individual and Public Persuasion (six items, α?=?.80). Study results indicate that CREBS can be used for exploring the extent to which elementary school students in Turkey demonstrate four types of behavior to help prevent and resolve environmental problems and issues.  相似文献

This study examined the type of growth model that best fit within-year growth in oral reading fluency and between-student differences in growth. Participants were 2,465 students in grades 3–5. Hierarchical linear modeling (HLM) analyses modeled curriculum-based measurement (CBM) oral reading fluency benchmark measures in fall, winter, and spring with grade level and student characteristics (including special education and Limited English Proficiency status) as covariates. Results indicated that a discontinuous growth model fit the data better than a linear growth model, with greater growth in the fall than in the spring. Oral reading fluency growth rates also differed by grade and student characteristics. Implications for school practice and research are discussed.  相似文献

Despite the recent attention to text reading fluency, few studies have studied the construct of oral reading rate and accuracy in connected text in a model that simultaneously examines many of the important variables in a multi-leveled fashion with young readers. Using Structural Equation Modeling, this study examined the measurement and structural relations of the rate and accuracy of variables important in early reading: phonemic blending, letter sounds, phonograms, decoding, single-word reading, reading comprehension, and text reading as well as reading comprehension among second grade readers. The effects from phonemic blending fluency and letter sound fluency to decoding were completely mediated by phonogram fluency, decoding fluency, single-word reading fluency, and reading comprehension had direct effects on the text reading fluency of the second grade students. Understanding the relationship among the many component skills of readers early in their reading development is important because a deficiency in any of the component skills has the potential to affect the development of other skills and, ultimately, the development of the child as a proficient reader.  相似文献

The purpose of this study was to identify subgroups of adult basic education (ABE) learners with different profiles of skills in the core reading components of decoding, word recognition, spelling, fluency, and comprehension. The analysis uses factor scores of those 5 reading components from on a prior investigation of the reliability and construct validity of measures of reading component skills (MacArthur, Konold, Glutting, & Alamprese, 2010). In that investigation, confirmatory factor analysis found that a model with those 5 factors fit the data best and fit equally well for native and non-native English speakers. The study included 486 students, 334 born or educated in the United States (native) and 152 not born nor educated in the US (non-native) but who spoke English well enough to participate in English reading classes. The cluster analysis found an 8-cluster solution with good internal cohesion, external isolation, and replicability across subsamples. Of the 8 subgroups, 4 had relatively flat profiles (range of mean scores across factors <0.5 SD), 2 had higher comprehension than decoding, and 2 had higher decoding than comprehension. Profiles were consistent with expectations regarding demographic factors. Non-native speakers were overrepresented in subgroups with relatively higher decoding and underrepresented in subgroups with relatively higher comprehension. Adults with self-reported learning disabilities were overrepresented in the lowest performing subgroup. Older adults and men were overrepresented in subgroups with lower performance. The study adds to the limited research on the reading skills of ABE learners and, from the perspective of practice, supports the importance of assessing component skills to plan instruction.  相似文献

The purpose of this paper is to examine the talk of older athletes, with particular focus on how the context of sport helps them negotiate the ageing process. It draws on personal stories provided by 44 World Masters Games competitors (23 women; 21 men; aged 56–90 years; M = 72). Four themes emerged: ‘There's no such thing as old’ (a story of avoiding old age); ‘Keep moving’ (a story of fighting the ageing process); ‘Fun, fitness, friendship … [and] competing’ (a story of redefining self and ‘old age’) and; ‘Making the most of your life … with the capabilities that you still have’ (a story of adaptation and acceptance). Together, the four themes show how through sports participation older individuals can simultaneously resist, redefine and accept the ageing process. These stories of a ‘sporting later life’ allow for alternative meanings to the dominant ‘declining body’ narrative of ageing. Therefore, these narratives present the possibility for personal, pedagogical and social transformation.  相似文献
