Involving students in the co-design of educational curricula and practices can benefit both students and teachers. Students who participate in co-design may show better learning or increased agency or engagement. In the present study, we investigated what kind of science knowledge or practices can be learned by student co-designers while engaging in co-design practices and how that learning happens with six high school students. We created a model to guide the analysis of students’ learning with technology in co-designing processes. The results revealed that students learned engineering design process even if no explicit instruction on engineering learning was given. Also, our analysis suggested that co-designing with technology enabled learning of the engineering design process and potentially furthered learning of science because it promoted knowledge integration. The results have implications for understanding and enhancing engineering design and science learning through co-designing with technology.

The effects of parent–child conversation and object manipulation on children's learning, transfer of knowledge, and memory were examined in two museum exhibits and conversations recorded at home. Seventy‐eight children (Mage = 4.9) and their parents were randomly assigned to receive conversation cards featuring elaborative questions about exhibit objects, the physical objects themselves, both, or neither, before their exhibit visits. Dyads who received the cards engaged in more elaborative talk and joint nonverbal activities with objects in the first exhibit than those who did not. Dyads who received objects engaged in the most parent–child joint talk. Results also illustrate transfer of information across exhibits and from museum to home. Implications for understanding mechanisms of informal learning and transfer are discussed. 相似文献

Although microbes directly impact everyone's health, most people have limited knowledge about them. In this article, we describe a museum and media public education campaign aimed at helping diverse audiences better understand emerging knowledge about microbes and infectious disease. Funded primarily by the Science Education Partnership (SEPA) program of the National Institutes of Health, this campaign involved crosscutting programs designed to extend impacts throughout a broad public audience. Collaborations with partners from public media, libraries, science education, the social sciences, and biomedical research centers extended our outreach to local and national audiences of adults and youth. Our campaign developed programs for radio broadcast, schools, libraries, museums, and publishers to ultimately reach over eight million people. In addition, we conducted a series of research studies focused on understanding the mental models that people create of the complex concepts of microbes and infectious disease and on how to engage hard‐to‐reach adolescents with this science content. These studies furthered our understanding of how people reason about unseen phenomena, the kinds of materials that might intrigue youth who claim little interest in science, and how to begin to combat misinformation pervasive in this field. Our comparisons of expert, teacher, and teen reasoning about microbes revealed their distinct mental models on the topics of infection, vaccination, and immune response. Our investigation of comics confirmed their power to motivate teenagers to want to read more about science. Across all levels of science identity, we found that youth were more engaged with the comics than with comparable essays. Together, these findings provide insights into how to educate a diverse public about emerging biomedical research. 相似文献

School achievement among black, white, and Hispanic elementary school children was investigated, and efforts were made to study the beliefs about academic achievement of the children and their mothers. A total of approximately 3,000 first, third, and fifth graders enrolled in 20 schools in the Chicago metropolitan area were given achievement tests in mathematics and reading. Black and Hispanic children performed at a significantly lower level than white children, but at fifth grade ethnic differences in mathematics scores were no longer significant when mothers' education was statistically controlled. This was not the case in reading, where differences were found after controlling for the effects of mothers' education. Interviews with subsamples of approximately 1,000 mothers and children revealed greater emphasis on and concern about education among minority families than among white families. Black and Hispanic children and mothers evaluated the children and their academic abilities highly; they were positive about education and held high expectations about the children's future prospects for education. Mothers of minority children and teachers in minority schools believed more strongly than white mothers and teachers in the value of homework, competency testing, and a longer school day as means of improving children's education. 相似文献

This study examined whether families’ conversational reflections after a STEM (science, technology, engineering, and mathematics)-related experience in a museum promoted learning transfer. 63 children (M = 6.93 years; 30 girls; 57% White, 17.5% Latinx, 8% Asian, 5% African American, 9.5% mixed, 3% missing race/ethnicity) and their parents received an engineering demonstration, engaged in a building activity, and either recorded a photo-narrative reflection about their building experience or not at the museum. Thirty-six of these families completed a building activity with different materials weeks later at home, and the majority (77%) evidenced learning transfer of the building principle demonstrated at the museum. Those who participated in the photo-narrative reflection at the museum also showed learning transfer by talking more about STEM during the home building activity. 相似文献

Young children have performed poorly in spatial tasks that require the scaling and reconstruction of a configuration. The present research investigated whether or not children's reconstructions nevertheless preserved the relative positions of objects within the configuration. In Experiment 1, preschoolers (ages 4 and 5), young elementary school children (ages 6 and 7), and adults were asked to reconstruct symmetric configurations of six objects that were depicted on simple maps of an empty room. Most subjects preserved the overall configuration of objects, but preschoolers placed the objects far from the correct locations. Many of the preschoolers' reconstructions contained systematic transformations; many reconstructions were off-center and too small or too large. In Experiment 2, the configurations were asymmetric, and preschoolers performed substantially worse than in Experiment 1. Experiment 3 demonstrated that preschoolers could reconstruct the asymmetric configurations when scaling was not required. Taken together, the results reveal that even young children can represent and transform an entire configuration of objects. At the same time, the results reveal important developmental differences. 相似文献

Teachers use remote labs and simulations to augment or even replace hands-on science learning. We compared undergraduate students’ experiences with a remote lab and a simulation to investigate beliefs about and learning from the interactions. Although learning occurred in both groups, students were more deeply engaged while performing the remote lab. Remote lab users felt and behaved as though they completed a real scientific experiment. We also examined whether realistic visualizations improved the psychological and learning experiences for each lab. Students who watched live video of the device collecting their data in the remote lab felt most engaged with the task, suggesting that it is the combination of the realistic lab and realistic video that was of the greatest benefit. 相似文献

How do concrete objects that cue real-world knowledge affect students' performance on mathematics word problems? In Experiment 1, fourth- and sixth-grade students (N = 229) solved word problems involving money. Students in the experimental condition were given bills and coins to help them solve the problems, and students in the control condition were not. Students in the experimental condition solved fewer problems correctly. Experiment 2 tested whether this effect was due to the perceptually rich nature of the materials. Fifth-grade students (N = 79) were given: perceptually rich bills and coins, bland bills and coins, or no bills and coins. Students in the perceptually rich condition made the most errors; however, their errors were least likely to be conceptual errors. Results suggest that the use of perceptually rich concrete objects conveys both advantages and disadvantages in children's performance in school mathematics. 相似文献

To use a symbol to solve a problem, children must achieve representational insight; they must realize that the symbol stands for its referent. Moreover, they must keep this relation in mind as they attempt to use the symbol. The present studies investigated the achievement and maintenance of representational insight. 3-year-olds were asked to use a scale model of a room to find a toy hidden in the room. In Study 1a, children first watched as a small toy was hidden in the model. They then waited either 20 sec, 2 min, or 5 min before attempting to find a similar, larger toy that was hidden in the corresponding place in the room. All children experienced all delay intervals; three groups experienced the delays in different orders. There was a dramatic effect of delay order. The children who experienced the 20-sec delay on their first trial generally performed well throughout the 6 trials, but the children who experienced a 5-min delay first almost always failed to find the toy in the room, even on subsequent trials with shorter delays. Additional studies revealed that the negative effects of the initial long delay could be overcome by providing reminders of the model and its relevance (Studies 2 and 3) or by giving children prior experience in using the model (Study 4). The results indicate that keeping a symbol-referent relation in mind can be difficult for 3.0-year-old children. This research is discussed in terms of the importance of maintaining representational insight. 相似文献
