Integrating K-W-L Prompts into Science Journal Writing: Can Simple Question Scaffolding Increase Student Content Knowledge?

Wagner, Brandon Joel 24 September 2014 (has links)
Writing-to-learn strategies have been administered in the past to enrich student learning. The purpose of this study was to see if K-W-L prompts in science journal writing could benefit student content knowledge within biology. Two high school biology classes were provided with learning journals. The journals given to the students during the treatment unit were provided with K-W-L question prompts to guide student learning while during the comparison unit students were given an open ended writing assignment. Pre and posttests were administered to determine student-learning gains. Student motivations and opinions of the treatment were collected through student interviews. The combined results were used to determine to what extent could K-W-L prompts in science journal writing influence comprehension of content knowledge. This study found there to be no difference in student learning gains when utilizing the K-W-L literacy strategy versus another free-writing activity. When scored, student K-W-Ls total scores did correlate to student success on unit tests. This opens up the potential for K-W-Ls to serve as an adequate tool for formative assessment. Here the K-W-L could be expanded to enrich student question asking, potentially aid students learning English, and potentially be used by students without teacher scaffolding.

Using the Task Analysis Process with Teachers to Uncover Language Demands within an Eight-Week NGSS Summer Course

Plack, Leah 26 July 2017 (has links)
The state of Oregon has adopted the Next Generation Science Standards as well as the English Language Proficiency standards, both of which affect elementary school teachers. These standards adoptions challenge teachers and professional developers to rethink how they approach science conceptual understanding and language acquisition. The Math Science Partnership K-6 Instructional Specialist Grant made the decision to incorporate a Task Analysis process, which asks the participant to analyze the demands of a content-based task in the domains of content knowledge, analytical skills and language, into six eight-week summer courses focused on the Next Generation Science Standards. A pre and post-assessment was created to determine if any growth in teacher understanding of the demands of a science task could be observed as a result of engaging in the Task Analysis process. A four point rubric was created to score participant responses. Two research questions were developed: 1. How well does the ELPA21 Task Analysis tool help participants understand the language demands of a science task when used as part of an NGSS summer professional development course? 2. How effective is a work sample and scoring rubric protocol for measuring the impact of the Task Analysis process? Participants showed statistically significant growth in their analysis of a science task from pre to post-assessment responses, with particularly strong growth demonstrated in the domains of content and language. Further coding of responses revealed that participants frequently discussed vocabulary as both a language and content knowledge demand of a science task.

An awareness programme to improve participation of young women in the science, technology, engineering and mathematics (STEM) fields in South African universities

Toolo, Lineo Lynnette 06 1900 (has links)
The purpose of this study was to develop the i-STEM programme, an awareness initiative that would improve the participation of young women in the science, technology, engineering and mathematics (STEM) fields in South African universities. That would serve as an intervention measure to young women’s significantly low numbers in the STEM fields, causing a gender disparity in those fields. Young women are said to be overrepresented in the fields that are at a lower level, the so-called soft disciplines and of short-term duration at tertiary level. The STEM fields, on the other hand, are well-remunerated and high-status careers, perceived as the main solution for the unprecedented socioeconomic challenges that the world is experiencing, as a result of, mainly, climate change and lack of food security. The literature reviewed was focused on the participation of young women in the STEM fields in South Africa, Africa and globally, assisting the study to investigate the reasons for low numbers of young women in the STEM fields. The mixed method approach was of benefit to the nature of this study, a quantitative and qualitative enquiry. The study was conducted at two universities with completely different profiles, contact sessions and modes of content delivery. The third institution was the government department relating to higher education. For research design, data was collected from 111 participants who were involved with the STEM fields and/or university education. Two (2) lecturers, two (2) government officials and two (2) young female students were interviewed and 105 other participants completed the questionnaires. Some data were collected from participating institutions’ documents. Interpretation and analysis of such data, was done through concurrent, triangulation design, where data collection was done concurrently, i.e. in the same phase, in both the quantitative and qualitative manner. The main findings blamed the different ways in which boys and girls were socialised in their communities. Girls were more exposed to matters pertaining to food and caring while boys were more exposed to cars and machines, resulting in girls preferring socially orientated careers and the boys, mechanical ones. Those findings were used as the impetus to construct Phases 1, 2 and 3 of the developed awareness programme, i.e. ‘Identification’, ‘Induction’ and ‘Implementation’, whereby the departments of Basic Education and Higher Education and Training, together with universities, would identify learners and students as mentees and mentors, who will become the advocates for breaking the above stereotypes. Another discovery was that there is an element of cultural stereotyping in society, that the STEM fields were difficult and therefore meant for men, since they are supposed to be more demanding and not for women as soft targets; hence the environment was unsupportive of women. It also related to the classification of certain jobs as men’s and others as women’s territory. That theory was further extended through the finding that the STEM fields were more-costly than the social sciences and that most of them require a longer study period. As a result, young women who anticipate becoming mothers and wives, avoid them as careers, in consideration of their future cultural roles. Those findings influenced the last four phases of the i-STEM programme, i.e. ‘Impression’, ‘Integration’, ‘Intensification’ and ‘Ignition’, whereby cultural and classist stereotypes would be determined through baseline information and rooted out by synergy in terms of resources, research and effort by local, national and international stakeholders, as guided by the programme. / Curriculum and Instructional Studies / D.

Crossing the Cartesian divide : an investigation into the role of emotion in science learning

Staus, Nancy L. (Nancy Lynn) 02 March 2012 (has links)
Although many science educators and researchers believe that emotion is an important part of the learning process, few researchers have dealt with the topic in a systematic fashion. The purpose of this study was to examine the role of emotion in the learning process, particularly in the learning of science content. My study utilized a dimensional perspective which defined emotion in terms of arousal and valence, and drew on research from the fields of psychology and neuroscience to examine how emotion affects different aspects of cognition such as attention and memory. On the basis of these findings, I developed and tested a path model to investigate the predicted relationships among emotional arousal, valence, attention, intrinsic motivation and short- and long-term learning outcomes. I conducted the study in two phases. The first phase took place in a psychology laboratory in which participants watched either an exciting or neutral nature video, read a factual article related to the video and were tested on their learning. The second phase took place at the Oregon Coast Aquarium in which participants watched a narrated otter or sea lion presentation and took a short posttest after the show. In both phases, participants' emotional arousal, valence, attention, and motivation levels were also measured for inclusion in the model. The results indicated that emotional arousal was an important predictor of short-term learning in both experiments although its effect was fully mediated by attention at the aquarium. In addition, negative valence (displeasure) and intrinsic motivation were strong predictors of short-term learning in the laboratory experiment. At the aquarium, the narrator of the animal presentation strongly affected both attention and short-term learning—visitors who listened to a non-scripted rather than a scripted narration paid more attention and had significantly better short-term learning outcomes. In the aquarium study, emotional arousal correlated strongly with several measures of long-term learning. In particular, those who felt more arousal during the animal presentation were able to describe their experience at greater length and with more detail and complexity two to three months after their visit. My findings suggest that emotional arousal is an important component of science learning both directly and through its relationship with attention. Therefore, science educators in both informal and formal learning institutions may be able to increase both attention and learning outcomes by designing emotionally arousing learning experiences around the science content they wish to teach. In addition, the importance of narrator quality in the aquarium study suggests that narrators and teachers should be trained to deliver information in such a way that supports short- and long-term science learning. / Graduation date: 2012

Argumentation and equity in inquiry-based science instruction : reasoning patterns of teachers and students

Irish, Tobias E. L. 30 August 2012 (has links)
This multiple case study explores issues of equity in science education through an examination of how teachers' reasoning patterns compare with students' reasoning patterns during inquiry-based lessons. It also examines the ways in which teachers utilize students' cultural and linguistic resources, or funds of knowledge, during inquiry-based lessons and the ways in which students utilize their funds of knowledge, during inquiry-based lessons. Three middle school teachers and a total of 57 middle school students participated in this study. The data collection involved classroom observations and multiple interviews with each of the teachers individually and with small groups of students. The findings indicate that the students are capable of far more complex reasoning than what was elicited by the lessons observed or what was modeled and expected by the teachers, but that during the inquiry-based lessons they conformed to the more simplistic reasoning patterns they perceived as the expected norm of classroom dialogue. The findings also indicate that the students possess funds of knowledge that are relevant to science topics, but very seldom use these funds in the context of their inquiry-based lessons. In addition, the teachers in this study very seldom worked to elicit students' use of their funds in these contexts. The few attempts they did make involved the use of analogies, examples, or questions. The findings from this study have implications for both teachers and teacher educators in that they highlight similarities and differences in reasoning that can help teachers establish instructional congruence and facilitate more equitable science instruction. They also provide insight into how students' cultural and linguistic resources are utilized during inquiry-based science lessons. / Graduation date: 2013

Exploring the Development and Transfer of Case Use Skills in Middle-School Project-Based Inquiry Classrooms

Owensby, Jakita Nicole 11 April 2006 (has links)
The ability to interpret and apply experiences, or cases (Kolodner, 1993; 1997) is a skill (Anderson, et. al, 1981; Anderson, 2000) that is key to successful learning that can be transferred (Bransford, Brown and Cocking, 1999) to new learning situations. For middle-schoolers in a project-based inquiry science classroom, interpreting and applying the experiences of experts to inform their design solutions is not always easy (Owensby and Kolodner, 2002). Interpreting and applying an expert case and then assessing the solution that results from that application are the components of a process I call case use. This work seeks to answer three questions: 1. How do small-group case use capabilities develop over time? 2. How well are students able to apply case use skills in new situations over time? 3. What difficulties do learners have as they learn case use skills and as they apply case use skills in new situations? What do these difficulties suggest about how software might further support cognitive skill development using a cognitive apprenticeship (Collins, Brown and Newman, 1989) framework? I argue that if learners in project based inquiry classrooms are able to understand, engage in, and carry out the processes involved in interpreting and applying expert cases effectively, then they will be able to do several things. They will learn those process and be able to read an expert case for understanding, glean the lessons they can learn from it, and apply those lessons to their question or challenge. Furthermore, I argue that they may also be able to transfer interpretation, application, and assessment skills to other learning situations where application of cases is appropriate.

Evaluating the impacts of partnership: an electronic panel study of partnering and the potential for adaptive management

Waschak, Michael R. 21 August 2009 (has links)
There has been an increase in the use of partnerships as a policy prescription for improving education since the mid 1980's. This trend builds on nearly a century of reform movements in education. In order to improve education policy, this study focuses on the question of whether math and science education partnerships as typically constituted provide the necessary conditions for the adaptive management (sustainable and adaptable action) of local education problems by the participants. This qualitative study uses data derived from the views of 32 experts on math and science partnerships collected during an internet-based application of the Delphi methodology designed to develop testable elements of a logic model of partnerships in math and science education. The results of this study suggest that the implementation and content requirements built into grant programs that include partners as a condition in aid most often result in a narrow programmatic focus among the participants. Organizations choose to participate in disjointed serial interventions that support organizational needs or goals based on the availability of funding and partners for particular programmatic activities. They choose partners from among those who are interested in similar or complementary activities. The primary focus of STEM education partnerships is therefore on implementing and sometimes evaluating the funded programmatic activities and not on building a broader learning community. Activities or education problems that are not funded tend to be excluded from the activities and dialog of the policy-induced partnership. By limiting the scope of the collaboration we are limiting the potential for adaptive management and the value of these partnerships.
