This randomized controlled trial or ‘true experiment' examines the effects of a school garden intervention on the science knowledge of elementary school children. Schools were randomly assigned to a group that received the garden intervention (n?=?25) or to a waitlist control group that received the garden intervention at the end of the study (n?=?24). The garden intervention consisted of both raised-bed garden kits and a series of 19 lessons. Schools, located in the US states of Arkansas, Iowa, Washington, and New York, were all low-income as defined by having 50% or more children qualifying for the federal school lunch program. Participants were students in second, fourth, and fifth grade (ages 6–12) at baseline (n?=?3,061). Science knowledge was measured using a 7-item questionnaire focused on nutritional science and plant science. The survey was administered at baseline (Fall 2011) and at three time points during the intervention (Spring 2012, Fall 2012, and Spring 2013). Garden intervention fidelity (GIF) captured the robustness or fidelity of the intervention delivered in each classroom based on both lessons delivered and garden activities. Analyses were conducted using general linear mixed models. Survey data indicated that among children in the garden intervention, science knowledge increased from baseline to follow-up more than among control group children. However, science knowledge scores were uniformly poor and gains were very modest. GIF, which takes into account the robustness of the intervention, revealed a dose–response relation with science knowledge: more robust or substantial intervention implementations corresponded to stronger treatment effects. 相似文献

This article presents the findings from a teacher intervention in Dutch kindergartens aimed at improving teachers’ differentiation practices (DP) to better anticipate student differences. The intervention was designed to improve the match between student levels and curricular activities, in particular for high-ability students and consists of three components. A pretest–posttest cluster randomised design was used with three conditions: control (n = 34), pilot intervention (n = 32) and improved intervention (n = 34). Quantitative results demonstrate that the intervention fidelity was relatively high in the improved intervention. Correlations confirmed that teacher-reported DP were higher in schools where the intervention was more completely implemented. DP were enhanced in both intervention conditions, but showed greater improvement in the improved intervention. Qualitative data revealed process characteristics that reflect problems schools encounter with this intervention. Teachers can be supported in improving DP, but this requires school-wide intensive and long support. 相似文献

This paper reports a study which implemented and evaluated a method of student self‐assessment. The theme of the importance of marking criteria (Orsmond et al., 1996) is developed. Pairs of first‐year undergraduate biology students were asked to complete a poster assignment on a specific aspect of nerve physiology. The study was designed to allow the evaluation of (1) student self and tutor marking for individual marking criteria; and (2) student vs student marking of their poster work for individual marking criteria. A comparison between the tutor and the student self‐assessed mark reveals how important it is to consider the individual marking criteria rather than the overall mark. These results support our findings on peer assessment reported earlier (Orsmond et al., 1996). The results also illustrate the potential pitfalls that exist when making assumptions about the degree of student/student interaction and students’ marking ability. This study supports previous work which showed that self‐assessment is extremely useful in helping students reach their learning goals, i.e. it is a strong formative educational tool and can be used in order to bring about behavioural changes in students with regard to their own learning processes. 相似文献

Background: This exploratory study is part of a larger-scale research project aimed at building theoretical and practical knowledge of complex systems in students and teachers with the goal of improving high school biology learning through professional development and a classroom intervention.Purpose: We propose a model of adaptive expertise to better understand teachers’ classroom practices as they attempt to navigate myriad variables in the implementation of biology units that include working with computer simulations, and learning about and teaching through complex systems ideas.Sample: Research participants were three high school biology teachers, two females and one male, ranging in teaching experience from six to 16 years. Their teaching contexts also ranged in student achievement from 14–47% advanced science proficiency.Design and methods: We used a holistic multiple case study methodology and collected data during the 2011–2012 school year. Data sources include classroom observations, teacher and student surveys, and interviews. Data analyses and trustworthiness measures were conducted through qualitative mining of data sources and triangulation of findings.Results: We illustrate the characteristics of adaptive expertise of more or less successful teaching and learning when implementing complex systems curricula. We also demonstrate differences between case study teachers in terms of particular variables associated with adaptive expertise.Conclusions: This research contributes to scholarship on practices and professional development needed to better support teachers to teach through a complex systems pedagogical and curricular approach. 相似文献

This study considered outcomes when 27 academics explicitly developed and assessed student research skills in 28 regular (non-research methods) semester-length courses. These courses ranged from small (n?=?17) to medium-large (n = 222) and included those from first year to masters in business, engineering, health science, humanities and science, across five universities in three Australian cities. The two-year study used three data sets to determine the outcomes of development and assessment initiatives: student pre- (n?=?779) and post-questionnaires (n?=?601), interviews with students (n?=?46) one year after completing a course that developed research skills and interviews with academics (n?=?17) involved in developing and assessing student research skills. These multiple sources provided evidence that students developed a variety of discipline-specific research skills and that these skills were useful for subsequent studies and especially for employment. Academics indicated that the process of making explicit the development of student research skills led to enhancement of their teaching, helping the academics to clarify major course purposes as well as enabling them to provide more substantial feedback to students than in the past. Academics also indicated that this teaching process changed their understanding of disciplinary research and, for some, even suggested new directions in their research. 相似文献

This paper reports on a study where rubrics have been used to convey assessment expectations to students (n?=?176) in three different assessment situations in professional education. These situations are: (1) the development of a survey instrument, which was part of a course in statistics and epidemiology; (2) an inspection of a house, which was part of a course about the functions of buildings for real estate brokers and (3) a workshop in communication with patients, which was part of a course in the evaluation of diagnostic procedures and treatments of oral infections in dental education. In all situations, students’ perceptions and uses of the rubrics were investigated. Findings suggest that it is indeed possible to convey expectations to students through the use of rubrics, in the sense that students not only appreciate the efforts to make assessment criteria transparent, but may also use the criteria in order to support and self-assess their performance. Important features of the rubrics, which were found to facilitate students’ understanding and use of the criteria in these situations, are presented and discussed. 相似文献

The seeming lack of motivation of many academically gifted students is an area of frustration and concern for many parents, teachers, and psychologists. This article explores two studies in which researchers designed interventions to improve academic achievement. Both interventions were created using the Achievement‐Orientation Model. The first study matched the intervention to the student and found that the students' grades increased over the intervention period, t(45) = 2.56, p = .014, d = .38. Students using treatments linked to goal valuation and environmental perceptions showed the greatest academic grade growth; the self‐efficacy and self‐regulation groups showed little or no grade improvement. Building on the finding that goal valuation was important, the second study used a mixed‐methods design to pilot an intervention focused on goal valuation and student autonomy. The results of this study were mixed, as the intervention appeared to help two of the three students. Although these studies offer further insight into possibilities for promoting academic achievement among gifted students, further research examining how to best support and foster academic achievement in underachieving gifted students is needed. © 2012 Wiley Periodicals, Inc. 相似文献

AbstractThis study uses a regression discontinuity design to evaluate the impact of seventh-grade interventions delivered by 25 schools on the reading and school engagement outcomes of struggling readers. Students in participating schools were assigned to intervention (n?=?1,495) or comparison (n?=?4,397) conditions, based on their state reading performance and reading fluency scores in sixth grade. On the state reading test, intervention impact favoring the treatment group approached, but did not reach, statistical significance (p?=?.056, g?=?.15). On a measure of reading fluency, there was a significant interaction between the cut points schools chose for condition assignment and intervention impact (p?=?.015). In schools that chose a lower cut point, intervention students outperformed comparison students, while in schools that chose a higher cut point, comparison students outperformed intervention students. On a student self-report measure of school engagement, no significant differences between the intervention and comparison groups were observed (p?=?.83, g?=?.02). Implications for rigorous evaluation of interventions implemented by districts and schools under naturalistic conditions are discussed. 相似文献

This paper reports a study which implemented and evaluated a method of student self and peer assessment involving student constructed marking criteria. The theme of the importance of marking criteria (Orsmond et al ., 1996, 1997) is developed. Pairs of first-year undergraduate biology students were asked to complete a poster assignment. The study was designed to allow the comparison and evaluation of (1) student self and tutor marking for individual marking criteria; (2) student self and peer marking for individual marking criteria; and (3) student and tutor marking for student constructed and tutor provided individual marking criteria. The present study shows that: (a) students may be less able to discriminate between individual marking criteria which they have constructed compared to marking criteria that have been provided; (b) asking students to construct their own marking criteria in discussion with tutors or fellow students does not enhance agreement between student/tutor or student/student marking; and (c) allowing students to construct their own marking criteria may lead to different learning outcomes compared to providing students with a marking criteria. 相似文献

Worldwide there is a growing reliance on sessional teachers in universities. This has impacted all disciplines in higher education including medical anatomy programs. The objective of this review was to define the role and support needs of sessional anatomy teachers by reporting on the (1) qualifications, (2) teaching role, (3) training, and (4) performance management of this group of educators. A systematic literature search was conducted on the 27 July 2017 in Scopus, Web of Science, and several databases on the Ovid, ProQuest and EBSCOhost platforms. The search retrieved 5,658 articles, with 39 deemed eligible for inclusion. The qualifications and educational distance between sessional anatomy teachers and their students varied widely. Reports of cross‐level, near‐peer and reciprocal‐peer teaching were identified, with most institutes utilizing recent medical graduates or medical students as sessional teachers. Sessional anatomy teachers were engaged in the full spectrum of teaching‐related duties from assisting students with cadaveric dissection, to marking student assessments and developing course materials. Fourteen institutes reported that training was provided to sessional anatomy teachers, but the specific content, objectives, methods and effectiveness of the training programs were rarely defined. Evaluations of sessional anatomy teacher performance primarily relied on subjective feedback measures such as student surveys (n = 18) or teacher self‐assessment (n = 3). The results of this systematic review highlight the need for rigorous explorations of the use of sessional anatomy teachers in medical education, and the development of evidence‐based policies and training programs that regulate and support the use of sessional teachers in higher education.

Capturing evidence for dynamic changes in self-regulated learning (SRL) behaviours resulting from interventions is challenging for researchers. In the current study, we identified students who were likely to do poorly in a biology course and those who were likely to do well. Then, we randomly assigned a portion of the students predicted to perform poorly to a science of learning to learn intervention where they were taught SRL study strategies. Learning outcome and log data (257 K events) were collected from n = 226 students. We used a complex systems framework to model the differences in SRL including the amount, interrelatedness, density and regularity of engagement captured in digital trace data (ie, logs). Differences were compared between students who were predicted to (1) perform poorly (control, n = 48), (2) perform poorly and received intervention (treatment, n = 95) and (3) perform well (not flagged, n = 83). Results indicated that the regularity of students' engagement was predictive of course grade, and that the intervention group exhibited increased regularity in engagement over the control group immediately after the intervention and maintained that increase over the course of the semester. We discuss the implications of these findings in relation to the future of artificial intelligence and potential uses for monitoring student learning in online environments.

This study was designed to determine the relationship among teacher classroom management behavior, student engagement, and student achievement of middle and high school science students. These variables were investigated across varying levels of academic aptitude. Two week long units were taught by 30 experienced science teachers. During this period of time teacher classroom management behavior, student achievement (n = 570), student engagement (n = 269), and student academic aptitude (n = 649) were measured. Twelve selected management indicators from Georgia Teachers Performance Assessment Indicators (TPAI) were used to measure teacher classroom management behaviors. Regression analysis was used to determine the relationship between the variables, and appropriate post hoc procedures were used. Analyses showed that there was a significant relationship among all variables. Post hoc analysis showed that these results were consistent across levels of aptitude. Other relationships found were between student engagement and achievement, student aptitude and achievement, and student aptitude and engagement. Correlation coefficients were obtained for each individual management indicators. Those particular management behaviors which were correlated with achievement and engagement are: identifies students who do not understand directions and helps them individually, maintains learner involvement in lessons, reinforces and encourages the efforts of learners to maintain involvement, attends to routine tasks, uses instructional time efficiently, provides feedback to learners about their behavior, manages disruptive behavior among learners. 相似文献

Burnout is a significant problem in the workplace and recent research suggests burnout is also a growing concern for students. This study aimed to explore the transition from study to work, including exploring the impact of student burnout on work burnout. Australian health profession students (T1, n?=?86; T2, n?=?86; T3, n?=?57) from the disciplines of nursing, psychology, occupational therapy and social work were followed from their final year at university into their first two years at work. An online questionnaire which included measures of exhaustion, cynicism, professional efficacy, mental health, neuroticism, study/job demands and resources was administered at three time points, one year apart. Contrary to the hypotheses, burnout was higher in study than work for all dimensions of burnout. Study exhaustion and cynicism predicted work exhaustion and cynicism, respectively. These results demonstrate the importance of early intervention for burnout in university settings, both to decrease student burnout and to prevent future work burnout. 相似文献

We report the results of a study with 30 teachers designed to examine the effects of teacher knowledge on the achievement
of struggling readers. We worked with teachers of grades three, four, and five during a 10-day intervention focused on literacy
instruction and related linguistic knowledge, and we assessed their students’ learning across the year. Hierarchical models
of student outcomes indicated that lower-performing students in intervention classrooms showed significantly higher levels
of performance at year end on all literacy measures, compared with their peers in control classrooms (n = 140). In addition, teacher’s linguistic knowledge was related to improved student performance, regardless of condition.
Additional analyses including all students (n = 718) indicated that benefits for the lower performing students in intervention classrooms were shared by their classmates,
but to a more limited extent. 相似文献

ABSTRACTHistorically, higher education research has focused on traditional students (i.e., recent high school graduates at a residential, 4-year institutions), but community college students are quickly becoming the new traditional student (Jenkins, 2012). In the fall of 2011, more than one third (36%) of all students enrolled in postsecondary education and almost half (46.7%) of all students enrolled in a public postsecondary institution were enrolled at a community college (Knapp, Kelly-Reid, & Ginder, 2012). However, community colleges have struggled to match the persistence rates at other institutional types. The 2011 2-year public community college national 3-year persistence-to-degree rate was 26.9% (American College Testing [ACT], 2011). The purpose of this paper is to review the literature regarding the most prominent theoretical frameworks for community college student persistence and suggest a new theoretical construct. The resultant framework is termed the Collective Affiliation Model because it views the student’s sense of belonging with the college as only one of many senses of belonging in the student’s life (e.g., family, work). The Collective Affiliation Model does not view student dropout as the student’s inability to integrate into the life of the institution; rather, it views it as the institution’s inability to collectively affiliate with the student. This model’s strength is that it does not work from a student deficit model. Instead, it provides a new framework for researchers and practitioners to better understand and address student drop-out at community colleges. 相似文献
