Bibliography: pages 73-82. / Using 262 acknowledged science educators from 41 countries, Bybee developed a scale for measuring the ranked priorities of scientists, and others, with respect to twelve major global problems related to science and technology in 1984. In 1993 this scale was re-administered to samples of 76 Cape Town science educators, 55 Transkei science educators and 129 chemical engineering undergraduates at the University of Cape Town. High correlations ranging from r = 0.68 to r = 0.90 were obtained among the four samples' mean ranked priorities on the scale as a whole, over the ten year period. Among the top six global problems in 1984, five still received consistently high overall prioritisation in 1993, namely: population growth; world hunger and food resources; human health and disease; air quality and atmosphere; and water resources. The mean ranking of war technology as a priority declined by seven places over the ten year period. Educators surveyed in follow-up studies in 1993 made numerous recommendations for teaching these global problems. These included the use of the science-technology-society (STS) approach in science education; the introduction of a core school curriculum on environmental education; the encouragement of student participation in projects which help to reduce or eliminate such global problems; and the re-allocation of money spent on nuclear arms towards the satisfaction of human basic needs such as food, housing, health and water services. In a follow-up survey of twenty lecturers in engineering at the University of Cape Town in 1993 and 1994 important goals and issues singled out by individuals included the provision of mass housing and infrastructure; sanitation; urbanisation; job creation; the abuse of high technology in communications; technological illiteracy among decision makers; abuse and reduction of oceanic resources; photochemical smog; the prediction and possible control of droughts and floods; demands on the human race of the information explosion; electromagnetic wave hazards and pollution; resource depletion education and the dissemination of knowledge; the emergence and separation of C.P. Snow's "Two cultures"; and the myth of the peace dividend. Several of these issues were then subsequently included in 1995 in an updated, modified and extended form of the Bybee Scale. Currently a reliable and validated 15-item Scale -emerging from the findings of this dissertation - is being employed by other research workers in various parts of the new South Africa. During 1995 its chief use has been offering relevant input into, and providing empirical justification for, fundamental aspects of the policy of the current Reconstruction and Development Programme, as set out in the 1995 White Paper of the Government of National Unity.

In 2010, Oregon Department of Education (ODE) developed a set of rubrics designed to score a state required performance assessment targeting Science Inquiry (SI) and Engineering Design (ED) skills. During the development of the rubrics, ODE invited six panels of teachers to provide feedback on an early draft of the rubrics. This case study analyzed the teachers' feedback and the revisions of the rubrics to identify the types of feedback teachers offered and how ODE used that feedback to develop the rubrics. The results showed the teachers' feedback focused on defining the skills students were asked to demonstrate and distinguishing levels of student performance. There was clear evidence that the teachers' feedback had a substantial impact on the development of the rubrics. These results suggest that teachers can add substantial value during the development of a state issued assessment tool.

The implementation of scientific inquiry in the high school classroom has proven to be not only relevant and exploratory, but challenging and engaging as well. This style of curriculum design has been recognized as a primary means of achieving the goals and objectives set by the National Resource Council (NRC, 1996). While much research has shown that science inquiry helps students to gain understanding of content knowledge, little research has been conducted to assess gains in higher order thinking skills, specifically those related to data analysis (Anderson, 2002; Germann and Aram, 1996; Hofstein, Navon, Kipnis, and Mamlok-Naaman, 2005; Miner, Levy, and Century, 2009; Windschitl, Thompson, and Braaten, 2008; Zohar and Dori, 2003). Through a better understanding of the scientific inquiry process as well as insights into students' struggles with data analysis, we can better understand how to effectively implement strategies in the classroom that encourage the higher order thinking skill of data analysis. This mixed methods, multiple-case study investigated teacher practice in eight high school science inquiry units in the Portland, Oregon metropolitan area and the data analyses that students produced in their accompanying work samples. The results of this study indicate that students struggle to produce proficient analysis and interpretations of data. The areas of student struggle were in the areas that required higher order thinking: analyzing results, drawing conclusions, and communicating results. Furthermore, this research discusses areas of data analysis instruction that may benefit from professional development opportunities.

This mixed methods case study documents an effort to implement authentic science and engineering instruction in one teacher's ninth grade science classrooms in a science-focused public school. The research framework and methodology is a derivative of work developed and reported by Newmann and others (Newmann & Associates, 1996). Based on a working definition of authenticity, data were collected for eight months on the authenticity in the experienced teacher's pedagogy and in student performance. Authenticity was defined as the degree to which a classroom lesson, an assessment task, or an example of student performance demonstrates construction of knowledge through use of the meaning-making processes of science and engineering, and has some value to students beyond demonstrating success in school (Wehlage et al., 1996). Instruments adapted for this study produced a rich description of the authenticity of the teacher's instruction and student performance. The pedagogical practices of the classroom teacher were measured as moderately authentic on average. However, the authenticity model revealed the teacher's strategy of interspersing relatively low authenticity instructional units focused on building science knowledge with much higher authenticity tasks requiring students to apply these concepts and skills. The authenticity of the construction of knowledge and science meaning-making processes components of authentic pedagogy were found to be greater, than the authenticity of affordances for students to find value in classroom activities beyond demonstrating success in school. Instruction frequently included one aspect of value beyond school, connections to the world outside the classroom, but students were infrequently afforded the opportunity to present their classwork to audiences beyond the teacher. When the science instruction in the case was measured to afford a greater level of authentic intellectual work, a higher level of authentic student performance on science classwork was also measured. In addition, direct observation measures of student behavioral engagement showed that behavioral engagement was generally high, but not associated with the authenticity of the pedagogy. Direct observation measures of student self-regulation found evidence that when instruction focused on core science and engineering concepts and made stronger connections to the student's world beyond the classroom, student self-regulated learning was greater, and included evidence of student ownership. In light of the alignment between the model of authenticity used in this study and the Next Generation Science Standards (NGSS), the results suggest that further research on the value beyond school component of the model could improve understanding of student engagement and performance in response to the implementation of the NGSS. In particular, it suggests a unique role environmental education can play in affording student success in K-12 science and a tool to measure that role.

The goal of environmental education (EE) has always been to increase knowledge about the environment and to foster positive environmental attitudes. Increasingly, as the call for integrating EE programs into mainstream science curriculum intensifies, it is important to continue to evaluate the effectiveness of these programs not only through measures of change in knowledge and attitudes, but through the additional criteria of meeting the needs of different gender and ethnic groups. The purpose of this research was to identify whether a watershed education program was meeting the needs of diverse learners within the context of a year-long, integrated, sixth-grade science curriculum. This study specifically sought to answer the following questions: 1) Do differences exist between genders and ethnic groups in regards to change in environmental knowledge after participation in an environmental education program? and 2) Do differences exist between genders and ethnic groups in regards to changes in environmental attitudes after participation in an environmental education program? A mixed-methods approach consisting of a pre/post-test survey, interviews, and observational data was used to evaluate these questions. The quantitative results of the survey data suggests that, overall, students had statistically significant (p < 0.01) gains in environmental knowledge, but no change in attitude towards the environment after participation in the program. When subpopulations are broken down into gender and ethnic groups, however, there is statistically significant support for the idea that ethnic groups--and, to a lesser extent, gender groups--were affected differently by the program. One important finding was that Hispanic and Native American students had significantly less gain in knowledge than their White, Asian and African-American peers. Qualitative interviews and observations shed light on these findings and illustrate the experiences of students during the year-long program. Other findings, trends, observations, and opportunities for future research are also discussed.

Cooperative learning has been one of the most widely used instructional practices around the world since the early 1980's. Small learning groups have been in existence since the beginning of the human race. These groups have grown in their variance and complexity overtime. Classrooms are getting more diverse every year and instructors need a way to take advantage of this diversity to improve learning. The purpose of this study was to see if heterogeneous cooperative learning groups based on student achievement can be used as a differentiated instructional strategy to increase students' ability to demonstrate knowledge of science concepts and ability to do engineering design. This study includes two different groups made up of two different middle school science classrooms of 25-30 students. These students were given an engineering design problem to solve within cooperative learning groups. One class was put into heterogeneous cooperative learning groups based on student's pre-test scores. The other class was grouped based on random assignment. The study measured the difference between each class's pre-post gains, student's responses to a group interaction form and interview questions addressing their perceptions of the makeup of their groups. The findings of the study were that there was no significant difference between learning gains for the treatment and comparison groups. There was a significant difference between the treatment and comparison groups in student perceptions of their group's ability to stay on task and manage their time efficiently. Both the comparison and treatment groups had a positive perception of the composition of their cooperative learning groups.

It is important that students understand not only how their local watershed functions, but also how it is being impacted by impervious surfaces. Additionally, students need experience exploring the scientific and engineering practices that are necessary for a strong STEM background. With this knowledge students can be empowered to tackle this real and local problem using engineering design, a powerful practice gaining momentum and clarity through its prominence in the recent Framework for K-12 Science Education. Twenty classes of suburban sixth-graders participated in a new five-week Watershed Engineering Design Unit taught by their regular science teachers. Students engaged in scientific inquiry to learn about the structure, function, and health of their local watersheds, focusing on the effects of impervious surfaces. In small groups, students used the engineering design process to propose solutions to lessen the impact of runoff from their school campuses. The goal of this evaluation was to determine the effectiveness of the curriculum in terms of student gains in understanding of (1) watershed function, (2) the impact of impervious surfaces, and (3) the engineering design process. To determine the impact of this curriculum on their learning, students took multiple-choice pre- and post-assessments made up of items covering the three categories above. This data was analyzed for statistical significance using a lower-tailed paired sample t-test. All three objectives showed statistically significant learning gains and the results were used to recommend improvements to the curriculum and the assessment instrument for future iterations.

The post-pandemic classroom dealt with not only the mental health struggles of educators and students, but also the technological and virtual learning dependence in a time ridden with misinformation. At this time, it was important to not only consider the purpose and intent of science education as a learning experience, but also pedagogical approaches that seek to actualize this very intent. The pedagogy of science has at its foundation the experience of inquiry beginning from self and expanding to the natural world. Explained by educationalists like John Dewey and Thomas Kuhn and in theory, implemented into classrooms through the Next Generation Science Standards, the potential of inquiry is to expand from a first-person experience to the wellbeing of community and society. Moreover, contemplative philosophies, such as Yoga, Vedanta, and Buddhist mindfulness, provide novel, yet ancient approaches to teaching this awareness through their pedagogical framework. Contemplative or spiritual pedagogies are those whose approach involves the exploration of subjectivity through introspection and empathy practices like meditation, journaling, and activism. In all, as the practitioner of these traditions and the educator-researcher in the classroom, I performed a qualitative study in phenomenology. I taught an AP Physics C class influenced by the lens of this contemplative paradigm, although this was not detached from the usual curriculum or interventional by nature. From emergent themes in the past student work and evaluation of their experience, I discovered the following: when an educator applied the approach of these wisdom traditions into the classroom curriculum, the resulting environment impacted a positive learning experience as it pertained to engaging science as inquiry. This study had an ambition to provide a novel approach to teaching and learning inquiry informed by the above-mentioned traditions.

Thesis (M.Ed. (Science Education)) -- University of Limpopo, 2016 / This study investigated Grade 11 learners’ misconceptions about force. An exploratory design was used with six schools. A purposive sample of 190 learners studying Physical Sciences was tested for common misconceptions using the Force Concept Inventory (FCI). Furthermore, the prevalence of the misconceptions was also determined. Focus group discussions were used to determine the origin of learners’ misconceptions. Descriptive analysis of the FCI revealed extensive misconceptions about Newtonian physics amongst Grade 11 learners with a prevalence range of 70% to 90%. The researcher surmised that the origins of these prevalent misconceptions are inherent of the sources of misconceptions that learners encounter in the formal physics classrooms: teachers and textbooks. Textbooks used by learners do not take into account possible misconceptions that learners might have. Thus, it might be difficult for teachers to identify possible misconceptions-prone topics based on their own background. The researcher recommends interactive teaching strategies.

This study involved a comparative analysis of reforms in the organization and structure of curricula and instruction in science education in the United States during the last decades of the nineteenth and twentieth centuries. A review of literature of these periods revealed similar concerns and goals for science instructional reform in schools. With the use of primary and secondary sources from these decades, a comparison of the conditions surrounding the reform movements was made. The author explored such concerns as educational norms, aims, values, customs, curricula content, instructional methods, psychological bases and their relationships with the technological and scientific cultures of the times. This comparison characterized common factors associated with the two reform movements. A historical characterization of the two reform periods identified relationships and responses of science education reform to social, educational, scientific, technological, and economic influences. These relationships and responses represent some of the common factors that late-nineteenth century and late-twentieth century reform movements in science education share. The author determined that although the terms, phrases, and jargon used by late-nineteenth century science education reformers sound similar to those used today, the reform efforts are not as similar as they seem. Different meanings of reform terminology used by educators of the two time periods resulted in science education means and goals that are distinct for each period, although the terminology used to describe these ideals sounds and appears very similar. This study shows how science education reforms in the late-nineteenth and late-twentieth centuries responded to the world of which they were a part, and how under apparent similar conditions, responses of reformers appear similar, but in reality are different. / Ph.
