Standardized test outcomes for students engaged in inquiry‐based science curricula in the context of urban reform

Considerable effort has been made over the past decade to address the needs of learners in large urban districts through scaleable reform initiatives. We examine the effects of a multifaceted scaling reform that focuses on supporting standards based science teaching in urban middle schools. The effort was one component of a systemic reform effort in the Detroit Public Schools, and was centered on highly specified and developed project‐based inquiry science units supported by aligned professional development and learning technologies. Two cohorts of 7th and 8th graders that participated in the project units are compared with the remainder of the district population, using results from the high‐stakes state standardized test in science. Both the initial and scaled up cohorts show increases in science content understanding and process skills over their peers, and significantly higher pass rates on the statewide test. The relative gains occur up to a year and a half after participation in the curriculum, and show little attenuation with in the second cohort when scaling occurred and the number of teachers involved increased. The effect of participation in units at different grade levels is independent and cumulative, with higher levels of participation associated with similarly higher achievement scores. Examination of results by gender reveals that the curriculum effort succeeds in reducing the gender gap in achievement experienced by urban African‐American boys. These findings demonstrate that standards‐based, inquiry science curriculum can lead to standardized achievement test gains in historically underserved urban students, when the curriculum is highly specified, developed, and aligned with professional development and administrative support. © 2008 Wiley Periodicals, Inc.

Bridging scientific reasoning and conceptual change through adaptive web‐based learning

This study reports an adaptive digital learning project, Scientific Concept Construction and Reconstruction (SCCR), and examines its effects on 108 8th grade students' scientific reasoning and conceptual change through mixed methods. A one‐group pre‐, post‐, and retention quasi‐experimental design was used in the study. All students received tests for Atomic Achievement, Scientific Reasoning, and Atomic Dependent Reasoning before, 1 week after, and 8 weeks after learning. A total of 18 students, six from each class, were each interviewed for 1 hour before, immediately after, and 2 months after learning. A flow map was used to provide a sequential representation of the flow of students' scientific narrative elicited from the interviews, and to further analyze the level of scientific reasoning and conceptual change. Results show students' concepts of atoms, scientific reasoning, and conceptual change made progress, which is consistent with the interviewing results regarding the level of scientific reasoning and quantity of conceptual change. This study demonstrated that students' conceptual change and scientific reasoning could be improved through the SCCR learning project. Moreover, regression results indicated students' scientific reasoning contributed more to their conceptual change than to the concepts students held immediately after learning. It implies that scientific reasoning was pivotal for conceptual change and prompted students to make associations among new mental sets and existing hierarchical structure‐based memory. © 2009 Wiley Periodicals, Inc.

Students' environmental NOS views,compassion, intent,and action: Impact of place‐based socioscientific issues instruction

Preparing students to achieve the lofty goal of functional scientific literacy entails addressing the normative and non‐normative facets of socioscientific issues (SSI) such as scientific processes, the nature of science (NOS) and diverse sociocultural perspectives. SSI instructional approaches have demonstrated some efficacy for promoting students' NOS views, compassion for others, and decision making. However, extant investigations appear to neglect fully engaging students through authentic SSI in several ways. These include: (i) providing SSI instruction through classroom approaches that are divorced from students' lived experiences; (ii) demonstrating a contextual misalignment between SSI and NOS (particularly evident in NOS assessments); and (iii) framing decision making and position taking analogously—with the latter being an unreliable indicator of how people truly act. The significance of the convergent parallel mixed‐methods investigation reported here is how it responds to these shortcomings through exploring how place‐based SSI instruction focused on the contentious environmental issue of wolf reintroduction in the Greater Yellowstone Area impacted sixty secondary students' NOS views, compassion toward those impacted by contentious environmental issues, and pro‐environmental intent. Moreover, this investigation explores how those perspectives associate with the students' pro‐environmental action of donating to a Yellowstone environmental organization. Results demonstrate that the students' NOS views became significantly more accurate and contextualized, with moderate to large effect, through the place‐based SSI instruction. Through that instruction, the students also exhibited significant gains in their compassion for nature and people impacted by contentious environmental issues and pro‐environmental intent. Further analyses showed that donating students developed and demonstrated significantly more robust and contextualized NOS views, compassion for people and nature impacted by contentious environmental issues, and pro‐environmental intent than their nondonating counterparts. Pedagogical implications include how place‐based learning in authentic settings could better prepare students to understand NOS, become socioculturally aware, and engage SSI across a variety of contexts.     

Santayana on Democracy

In his clever On Self-Government: First Dialogue, Santayanal has presented the keenest brief inquiry into the virtue of democracy that it is my fortune to know. Imputed to Socrates and Stranger, the dialogue proceeds after the Socratic manner into a detached, academic (and wholly interesting) discussion of the supposed oracular pronouncement: “Right government rests on the will of the governed.”     

The implementation of a geospatial information technology (GIT)‐supported land use change curriculum with urban middle school learners to promote spatial thinking

This study investigated whether a geospatial information technology (GIT)‐supported science curriculum helped students in an urban middle school understand land use change (LUC) concepts and enhanced their spatial thinking. Five 8th grade earth and space science classes in an urban middle school consisting of three different ability level tracks participated in the study. Data gathering methods included pre/posttest assessments, daily classroom observations, daily teacher meetings, and examination of student produced artifacts. Findings indicated that content knowledge about environmental issues associated with LUC and spatial thinking skills involved with aerial and remotely sensed (RS) imagery interpretation increased for all learners. In most content and skill area clusters, effect sizes were larger for lower and middle track learners than for upper track learners. Achievement for spatial thinking items increased for all ability level tracks. The curriculum implementation appeared effective for enhancing spatial thinking skills involved with RS image interpretation to identify objects and investigate ground cover features. Learners at all ability levels had difficulty interpreting time‐sequenced images. Influencing learning contexts including curriculum design principles and instructional strategies are discussed. The findings from this study provide support that spatial thinking can be learned, can be taught formally to all students in an urban middle school, and can be supported by appropriately designed tools, technologies, and curriculum. © 2011 Wiley Periodicals, Inc., Inc.

Self‐concept and science achievement: Investigating a reciprocal relation model across the gender classification in a crosscultural context

Science achievement and self‐concept are articulated in this study to examine a model of reciprocal relationship during a crosscultural transition. Trend data have been gathered to assess changes of the perceived English importance before and after Hong Kong's sovereignty handover from Britain to China. The data analyses were conducted four times across dimensions of gender and timing over which the political transition took place. Besides small gender differences in the statistical results, weak but significant reciprocal relationships have been found between science achievement and self‐concept. In line with a policy of switching the medium of instruction from English to Chinese in most secondary schools, interpretation of different path coefficients obliges incorporation of cross‐cultural understanding in science education. © 2006 Wiley Periodicals, Inc.

Understanding food processing and systems: Pilot testing a standards‐aligned middle school curriculum

Consumer confidence and trust, as it relates to the food system, is one of the most sensitive areas within consumers’ understanding of food. Surveys have shown that a large majority of people would like to learn more about agriculture and food manufacturing, with young people being among those most eager for more information about where their food comes from. Food‐focused educational resources often go unused due to teachers’ lack of familiarity with the subject area, the pressures of standardized testing, and lack of alignment to state content standards. Building on the success of the Hands On Classrooms platform that developed and validated curricula with high adoption rates by teachers and a demonstrated impact on student knowledge and self‐efficacy, a new curriculum on food system and food processing was developed and pilot tested. Two teachers from rural Virginia and Tennessee participated in the study. Both teachers received online professional development prior to implementation. Students were given pretests and posttests to measure (a) what impact does the curriculum have on students’ knowledge of food systems and processing and (b) to what extent does the curriculum have an impact on student's self‐reported skills related to these topics? A total of 87 students completed the assessments and showed significant improvements from pretest to posttest on both knowledge (p < .001) and skills (p < .001) related specifically to where food comes from and how it is processed, content that is typically not covered in middle school curriculum. Further research can be undertaken to measure the impact on others in different geographic and socioeconomic areas to provide additional data to validate the program.     

The writing on the wall: Classroom context,curriculum implementation,and student learning in integrated,community‐based science projects

In this study we examined curriculum integration in new ways by exploring the link between classroom context, the implementation of community‐based, integrated science projects, and the subsequent student learning. The literature is inconsistent regarding the benefits of an integrated approach to curriculum. The research design was a multiple case study conducted in two classrooms in different schools. We employed a “worldly interpretive framework” that recognizes and embraces the importance of context in framing curriculum practices and outcomes. We found that similar projects in the two classrooms produced distinctly different (and equally valid) outcomes—focused either on bounded discipline‐specific knowledge or, alternatively, on issues and problems that transcended disciplinary boundaries. © 2008 Wiley Periodicals, Inc.

The Effects of a Stress Management Course on Counselors‐in‐Training

The effects of a stress management course on the stress knowledge and coping techniques of 101 graduate students in counseling were examined. Participants, drawn from various racial groups, were typically female (79%) and 21 to 55 years of age. Seven of the 8 null hypotheses were rejected. There were significant differences on 6 of the 7 dependent variables (overall knowledge of stress, perceived state and trait anxiety, stress response to positive and negative self‐statements, and general and current stress level). The treatment group learned and implemented stress management strategies to better cope with stress. Recommendations and further directions for research are offered.     

The effect of reflective discussions following inquiry‐based laboratory activities on students' views of nature of science

This research investigated the effect of reflective discussions following inquiry‐based laboratory activities on students' views of the tentative, empirical, subjective, and social aspects of nature of science (NOS). Thirty‐eight grade six students from a Lebanese school participated in the study. The study used a pretest–posttest control‐group design and focused on collecting mainly qualitative data. During each laboratory session, students worked in groups of two. Later, experimental group students answered open‐ended questions about NOS then engaged in reflective discussions about NOS. Control group students answered open‐ended questions about the content of the laboratory activities then participated in discussions of results of these activities. Data sources included an open‐ended questionnaire used as pre‐ and posttest, answers to the open‐ended questions that experimental group students answered individually during every session, transcribed videotapes of the reflective discussions of the experimental group, and semi‐structured interviews. Results indicated that explicit and reflective discussions following inquiry‐based laboratory activities enhanced students' views of the target NOS aspects more than implicit inquiry‐based instruction. Moreover, implicit inquiry‐based instruction did not substantially enhance the students' target NOS views. This study also identified five major challenges that students faced in their attempts to change their NOS views. © 2010 Wiley Periodicals, Inc. J Res Sci Teach 47: 1229–1252, 2010     

Discourse comprehension intervention for high‐functioning students with autism spectrum disorders: preliminary findings from a school‐based study

Many students with autism spectrum disorders (ASD) demonstrate comprehension difficulties. In the present study, 12 high‐functioning Swedish students with ASD (aged 10–15 years) took part in a naturalistic classroom‐based intervention to support comprehension of connected narrative discourse. An effective approach for supporting discourse comprehension in children with ASD was assumed to include: (i) providing teachers and students with a shared and explicit set of concepts for talking and thinking about the activity of comprehension, that (ii) can structure the child's discourse comprehension under scaffolding and modelling from the teacher. In the pre‐testing session, the students with ASD presented with poor discourse comprehension but receptive vocabulary and reading decoding skills close to normative performance. Post‐intervention test results, following 4 weeks of training, indicated specific and significant improvements in discourse comprehension. Support for the potential of this type of teaching was also obtained from teachers and students. The teachers reported that they would continue to use the same or similar comprehension instruction for 11 out of 12 students, and for multiple reasons, and students were also mostly positive to the training. Implications for practice and further research are discussed, as are limitations of the study.     

Effects of image‐based and text‐based active learning exercises on student examination performance in a musculoskeletal anatomy course

Research on the benefits of visual learning has relied primarily on lecture‐based pedagogy, but the potential benefits of combining active learning strategies with visual and verbal materials on learning anatomy has not yet been explored. In this study, the differential effects of text‐based and image‐based active learning exercises on examination performance were investigated in a functional anatomy course. Each class session was punctuated with an average of 12 text‐based and image‐based active learning exercises. Participation data from 231 students were compared with their examination performance on 262 questions associated with the in‐class exercises. Students also rated the helpfulness and difficulty of the in‐class exercises on a survey. Participation in the active learning exercises was positively correlated with examination performance (r = 0.63, P < 0.001). When controlling for other key demographics (gender, underrepresented minority status) and prior grade point average, participation in the image‐based exercises was significantly correlated with performance on examination questions associated with image‐based exercises (P < 0.001) and text‐based exercises (P < 0.01), while participation in text‐based exercises was not. Additionally, students reported that the active learning exercises were helpful for seeing images of key ideas (94%) and clarifying key course concepts (80%), and that the image‐based exercises were significantly less demanding, less hard and required less effort than text‐based exercises (P < 0.05). The findings confirm the positive effect of using images and active learning strategies on student learning, and suggest that integrating them may be especially beneficial for learning anatomy.

Examining the effect of teachers' adaptations of a middle school science inquiry‐oriented curriculum unit on student learning

Reform based curriculum offer a promising avenue to support greater student achievement in science. Yet teachers frequently adapt innovative curriculum when they use them in their own classrooms. In this study, we examine how 19 teachers adapted an inquiry‐oriented middle school science curriculum. Specifically, we investigate how teachers' curricular adaptations (amount of time, level of completion, and activity structures), teacher self‐efficacy (teacher comfort and student understanding), and teacher experience enacting the unit influenced student learning. Data sources included curriculum surveys, videotape observations of focal teachers, and pre‐ and post‐tests from 1,234 students. Our analyses using hierarchical linear modeling found that 38% of the variance in student gain scores occurred between teachers. Two variables significantly predicted student learning: teacher experience and activity structure. Teachers who had previously taught the inquiry‐oriented curriculum had greater student gains. For activity structure, students who completed investigations themselves had greater learning gains compared to students in classrooms who observed their teacher completing the investigations as demonstrations. These findings suggest that it can take time for teachers to effectively use innovative science curriculum. Furthermore, this study provides evidence for the importance of having students actively engaging in inquiry investigations to develop understandings of key science concepts. © 2010 Wiley Periodicals, Inc., J Res Sci Teach 48: 149–169, 2011
