Science education standards established by American Association for the Advancement of Science (AAAS) and the National Research Council (NRC) urge less emphasis on memorizing scientific facts and more emphasis on students investigating the everyday world and developing deep understanding from their inquiries. These approaches to instruction challenge teachers and students, particularly urban students who often have additional challenges related to poverty. We report data on student learning spanning 3 years from a science education reform collaboration with the Detroit Public Schools. Data were collected from nearly 8,000 students who participated in inquiry‐based and technology‐infused curriculum units that were collaboratively developed by district personnel and staff from the University of Michigan as part of a larger, district‐wide systemic reform effort in science education. The results show statistically significant increases on curriculum‐based test scores for each year of participation. Moreover, the strength of the effects grew over the years, as evidenced by increasing effect size estimates across the years. The findings indicate that students who historically are low achievers in science can succeed in standards‐based, inquiry science when curriculum is carefully developed and aligned with professional development and district policies. Additional longitudinal research on the development of student understanding over multiple inquiry projects, the progress of teacher enactment over time, and the effect of changes in the policy and administrative environment would further contribute to the intellectual and practical tools necessary to implement meaningful standards‐based systemic reform in science. © 2004 Wiley Periodicals, Inc.

ABSTRACT:The study aims to characterize contextual learning during class visits to science and natural history museums. Based on previous studies, we assumed that "outdoor" learning is different from classroom-based learning, and free choice learning in the museums enhances the expression of learning in personal context. We studied about 750 students participating in class visits at four museums, focusing on the levels of choice provided through the activity. The museums were of different sizes, locations, visitor number, and foci. A descriptive-interpretative approach was adopted, with data sources comprising observations, semistructured interviews with students, and museum worksheets. Analysis of the museum activities has yielded four levels of choice that affect learning from no choice to free choice activities. The effectiveness of learning was examined as well by looking at task behavior, linkage to the students' prior knowledge and their school's science curriculum, and linkage to the students' life and experience. Our findings indicate that activities of limited choice offered scaffolding, allowed the students to control their learning, and enhanced deeper engagement in the learning process. Within all the choice opportunities, the students connected the visit to their own life experiences and to their prior knowledge,

ABSTRACT:Teaching nonscience majors topics in biotechnology through case studies is the focus of this research. Our Biotechnology, Environment, and Related Issues module, developed within the Science for All framework, is aimed at elevating the level of students' scientific and technological literacy and their higher order thinking skills. The research goal was to investigate nonscience major students' ability to use various thinking skills in analyzing environmental and moral conflicts presented through case studies in the Biotechnology Module. The research population consisted of about 200 nonscience majors in eight classes of grades 10 -12 from heterogeneous communities. We found a significant improvement in students' knowledge and understanding and higher order thinking skills at all academic levels. The scores that low academic level students achieved in the knowledge and understanding category were higher than their high academic level peers' scores. In the higher order thinking skills-question posing, argumentation, and system thinking-a significant difference in favor of the high academic level students was found. The gap that had existed between low and high academic level students narrowed. Most students reported that the biotechnological topics that they had studied were interesting and relevant. Based on these results, we advocate a curriculum that exposes students to scientific controversies through case studies with environmental and moral implications. Our research has shown that this approach is likely to contribute to developing scientific and technological literacy along with higher order thinking skills of nonscience majors.

ABSTRACT:Museums are favorite and respected resources for learning worldwide. In Israel, there are two relatively large science centers and a number of small natural history museums that are visited by thousands of students. Unlike other countries, studying museum visits in Israel only emerges in the last few years. The study focused on the roles and perceptions of teachers, who visited four natural history museums with their classes. The study followed previous studies that aimed at understanding the role teachers play in class visits

This article describes a 3‐year study of school visits to four natural history museums and addresses the research agenda with regard to out‐of‐school learning. More specifically, the findings focus on the process of learning in museums. Comprehensive data collection allowed for an analysis of patterns of guided visits, the way the scientific content was conveyed to students, and the extent and types of social interactions thus enabled. Observations of 42 guided visits (grades 3–11) indicates that the main visitation pattern consisted of guide‐centered and task‐oriented activity. Analysis of questions asked by museum guides reveals that most of these questions required mainly lower‐order thinking skills. A common questioning pattern was to ask rhetorical questions as a means of carrying on the lecture. Detailed analysis of the scientific vocabulary used by the guides indicates that they used much scientific jargon, with limited explanation. There was only limited social mediation provided by teachers and museum guides. A minority of teachers were involved in the activities or in helping the guide to clarify or in helping the students to understand the explanations. The overall data indicate limited opportunities for meaningful learning, suggesting that the museums should shift from the traditional knowledge‐transmission model of teaching to a more socioculturally contextualized model. © 2007 Wiley Periodicals, Inc.

The ''Treasures in the Sea: Use and Abuse'' unit that deals with authentic socioscientific issues related to the Mediterranean was developed as part of a national effort to increase scientific literacy. The unit aimed to enhance active participation of the learners and encourage higher order thinking in class by applying teaching methods that reduce the unfamiliarity felt by students. This was expected through an explicit use of a variety of teaching and assessment-for-learning methods, suitable for Science for All students. Our main goal was to examine the culture of Science for All classes in which the unit was enacted. In order to address the main learning objectives, we monitored students' performances in tasks that required the higher order thinking skills of argumentation and value judgment, which are central constituents of decision-making processes. We show that while socioscientific issues were discussed in whole class and small group sessions, and students' argumentation improved, there is still a long way to go in applying a thinking culture in non-science major classes. We suggest that science teachers should shift from traditional content-based and valuefree approach, to a sociocultural approach that views science as a community practice and the students as active participants in decision-making processes.
