Multiple Outcomes of Class Visits to Natural History Museums: The Students’ View

The purpose of this study was to describe and understand the range of outcomes of class visits to natural history museums. The theoretical framework is based on the multifaceted process of learning in free choice learning environments, and emphasizes the unique and individual learning experience in museum settings. The study’s significance is in highlighting several possible cognitive as well as non-cognitive learning effects in museums class visits, by providing the student’s point of view. Data was collected by semi-structured interviews with 50 students in grades 6–8 on the day following the visit. We present evidence that students expressed several learning outcomes, connected directly and indirectly to the scientific content of the visit. Content oriented outcomes included acquiring scientific knowledge and making connections to prior knowledge; social oriented outcomes were identified in students’ statements regarding communicating knowledge and social aspects of learning; and interest oriented outcomes were evidenced by students’ expressions about emotions, interest and curiosity. The aggregate data addressed the common outcomes and the impact of class visits to natural history museums in the short term. Comparisons between two types of museums show significant differences in several aspects, regarding the exhibit and/or the activity type. Practical ideas for structuring the ultimate experience are included.     

Metacognition and Self-Regulation in James,Piaget, and Vygotsky

This article investigates the intertwined constructs of metacognition and self-regulation as they emerge in the works and theories of James, Piaget, and Vygotsky. To coordinate this exploration, we use an interpretive framework based on the relation of subject and object. In this framework, James’s perspective on metacognition and self-regulation is aligned with the Self, Piaget’s with the other and object, and Vygotsky’s with the medium or agency of language. We explore how metacognition and self-regulation function within the realm of human behavior and development as described in the works of each of these theorists. Key questions or issues that emerge for current research are outlined, and the limitations and benefits of each theorist’s perspective vis-à-vis metacognition and self-regulation are discussed.     

Mitigating Unintended Impacts? The Effects of Premiums for Underserved Populations in Performance-Funding Policies for Higher Education

Performance funding is an increasingly prevalent policy state officials use to allocate a portion of state funds to public colleges and universities. Researchers have begun to evaluate the effect of these policies, finding bleak evidence of their effectiveness in yielding intended outputs and suggesting the policies may even result in limited college access for underserved students. There may also be differences in policy effects depending on performance-funding policy designs, which vary considerably across states. Of particular interest to this study are premiums—financial bonuses to institutions—for promoting access and success for specified underserved student groups. Using difference-in-differences models and an original dataset on premiums in funding models, this study evaluates the impact of premiums for underserved students in performance-funding models on selectivity and the enrollment of minority and low-income students at 4-year universities from 1993 to 2014. We find that the share of both low-income and Hispanic students increases in institutions with performance-funding premiums for underserved students compared to institutions subject to performance funding without such premiums. Effects vary depending on premium type and longevity. The findings also reveal unexpected, negative effects of premiums on Black student enrollments. Our findings suggest that, by incorporating premiums, performance-funding model designers might prevent, minimize, or reverse the negative consequences of performance funding on vulnerable student groups. However, given variation in premium effects across student groups, performance- funding model designs should be tailored to local contexts.     

Surgical management of gastric stump cancer： a report of 37 cases

Objective: To observe the clinicopathological characteristics of gastric stump cancer (GSC) and evaluate the benefits of radical surgery of GSC. Methods: The clinicopathological characteristics and postoperative survival time of 37 GSC patients who underwent surgery were investigated retrospectively. The survival time was compared according to the type of surgical pTMN stage. Survival curves were traced by using Kaplan-Meier methods. Results: Most GSC (32/37) was detected in patients who had received Billroth Ⅱ reconstruction after partial gastrectomy for benign gastric disease. The lesser curvature side and the suture line of anastomosis were the most frequent sites where GSC occurred (27/37). Differentiated adenocarcinoma was the dominant histopathological type (24/37). The postoperative 5-year survival rate of early stage GSC patients (n=9) was significantly higher than advanced stage GSC (n=12) (55.6% vs 16.5%, xL2=1 1.48, P＜0.01). Five-year survival rate of 21 GSC patients with radical resection were 75% (3/4) for stage Ⅰ, 60% (3/5) for stage Ⅱ, 14.2% (1/7) for stage Ⅲ, and 0% (0/5) for stage Ⅳ respectively.The median survival time of 21 GSC patients who underwent radical resection was longer than those undergoing palliative operation (43.0m vs 13.0m, xL2=36.31, P＜0.01), the median survival time of stage Ⅳ patients with radical resection was 23.8months. Conclusions: Without remote metastasis, radical resection for GSC is possible, and is an effective way to improve the prognosis of GSC. Even in stage Ⅳ GSC, radical resection can still prolong the survival time. It is necessary for the patients with benign gastric diseases who received partial gastrectomy to carry out the endoscopy follow-up, especially in patients with Billroth Ⅱ reconstruction procedure at 15-20 years.     

Pressurizing the STEM Pipeline: an Expectancy-Value Theory Analysis of Youths’ STEM Attitudes

Over the past decade, there has been a strong national push to increase minority students’ positive attitudes towards STEM-related careers. However, despite this focus, minority students have remained underrepresented in these fields. Some researchers have directed their attention towards improving the STEM pipeline which carries students through our educational system and into STEM careers. Previous research has shown that expectancy-value theory (EVT) is useful for examining the short-term as well as long-term academic motivations and intentions of elementary age minority students. These findings provide insights into ways we may be able to potentially “patch” particular STEM pipeline leaks. In the current study, we advance this research by using EVT as a framework to examine the STEM attitudes of young students directly. We hypothesize that students’ academic-related expectancies for success and subjective task values will be associated with an increase in STEM attitudes. Data for this study was gathered over the course of a large-scale computing intervention which sought to increase students’ STEM interest. This computing intervention took place in an urban elementary school district located within the southeastern USA. Results from this study indicate that both intrinsic values and utility values predict students’ STEM attitudes but they influence attitudes related to the various dimensions of STEM differently. These findings demonstrate that EVT provides a useful framework, which can be integrated into future computing interventions, to help encourage positive STEM attitudes in young children, thus increasing the internal pressure (or flow) within the STEM pipeline.     

Examining evolutions in the adoption of metacognitive regulation in reciprocal peer tutoring groups

We aimed to investigate how metacognitive regulation is characterised during collaborative learning in a higher education reciprocal peer tutoring (RPT) setting. Sixty-four Educational Sciences students participated in a semester-long RPT-intervention and tutored one another in small groups of six. All sessions of five randomly selected RPT-groups were videotaped (70 h of video recordings). Analyses were focussed on identifying time-bound evolutions with regard to (a) the frequency of occurrence of metacognitive regulation, (b) the low-/deep-level approach to regulation, and (c) the initiative (by tutors/tutees) for metacognitive regulation. Logistic regression models allowing change points were adopted to study evolutions over time. The results indicated that RPT-groups increasingly adopt metacognitive regulation (i.e. orientation and evaluation) as the RPT-intervention progressed. Regarding RPT-groups’ regulative approach, the results revealed a significant evolution towards deep-level metacognitive regulation (i.e. orientation and monitoring), despite a dominant adoption of low-level regulation strategies. With regard to the initiative, the results demonstrated that tutees started to initiate RPT-groups’ monitoring significantly more frequently as they became familiar with the RPT-setting. Orientation, planning, and evaluation remained tutor-centred responsibilities.
