Impact Evaluation by Using Text Mining and Sentiment Analysis

Stuetzer, Cathleen M., Jablonka, Marcel, Gaaw, Stephanie 03 September 2020 (has links)
Web surveys in higher education are particularly important for assessing the quality of academic teaching and learning. Traditionally, mainly quantitative data is used for quality assessment. Increasingly, questions are being raised about the impact of attitudes of the individuals involved. Therefore, especially the analysis of open-ended text responses in web surveys offers the potential for impact evaluation. Despite the fact that qualitative text mining and sentiment analysis are being introduced in other research areas, these instruments are still slowly gaining access to evaluation research. On the one hand, there is a lack of methodological expertise to deal with large numbers of text responses (e.g. via semantic analysis, linguistically supported coding, etc.). On the other hand, deficiencies in interdisciplinary expertise are identified in order to be able to contextualize the results. The following contribution aims to address these issues. The presentation will contribute to the field of impact evaluation and reveals methodological implications for the development of text mining and sentiment analysis in evaluation processes.

Traditional Versus Nontraditional Instructional and Assessment Differences in 8th-Grade History-Social Science Achievement

Landers, John David 01 January 2018 (has links)
In southern California school districts, 8th grade students in history-social science (H-SS) classes did not perform well on the California Standards Test (CST). To improve student performance, middle school H-SS teachers in some districts received staff development in the use of authentic assessment, the understanding and application of multiple intelligences theory, and the application of a student centered focus in lesson design and instruction. The purpose of this comparative pretest/posttest study was to determine if there was significant achievement difference between 2 8th-grade U.S. H-SS classes taught in 2 districts. The research question addressed a significant difference in CST H-SS achievement scores between 8th-grade students taught using multiple intelligences strategies and authentic assessments (n = 28) and those who were taught using traditional strategies and curriculum assessments (n = 31). The theoretical foundation for this study was constructivism. Post-data from archived student scores on the CST H-SS test were collected and analyzed using an analysis of covariance (ANCOVA), controlling for varying differences in CST pre-test H-SS scores. There was a statistically significant difference in posttest CST H-SS scores between the 2 groups (F = 10.491, p < .002), with the nontraditional group scoring higher. Based on the findings, it is recommended that district leaders provide professional development opportunities for teachers in nontraditional constructivist instructional strategies that support student-centered instruction. These endeavors may lead to positive social change if H-SS teachers change instruction and assessment methods to improve student achievement, thus, meeting graduation requirements and enhancing citizenship development.

Attributes affecting adoption of pollinator conservation practices

Westlake, Shannon M 13 December 2019 (has links)
Pollinator conservation has recently become a topic of greater interest and research around the world as native insect pollinator species increasingly face population declines. In the United States, growing concerns regarding food security and decreased biodiversity have led to the creation of programmatic and best management practices (BMPs) promotional efforts among governmental and non-governmental organizations. These efforts seek to support pollinators on public and private lands by addressing the primary causes of decline (e.g., habitat loss and increased chemical use). Although these organizations have worked diligently to increase awareness and applicability of programs to private landholders, there is still a gap in pollinator BMP adoption. The purpose of my dissertation was to address the pollinator BMP adoption gap through empirical research with two primary goals: 1) develop and test a measurement instrument to investigate the current state of adoption in Mississippi, landholder attributes, and attribute influence on adoption intentions, and 2) conduct segmentation analyses to develop preliminary recommendations for future educational and outreach efforts to increase adoption of pollinator BMPs. I used two sociological theories to develop a questionnaire consisting of constructs measuring landholder attributes, including Attitudes, Injunctive Norms, Perceived Behavioral Control, Intentions, Knowledge, and Communication Channel Use. I conducted a selfministered mail survey during summer 2018 and received a 38.5% effective response rate. Relative to the first goal, major findings from the research included evidence of reliability and validity for the measurement constructs, landholders having more favorable than unfavorable Attitudes regarding the use of pollinator BMPs on their properties, and Perceived Behavioral Control as the strongest influence on adoption intentions compared to additional landholder attributes. Relative to the second goal, major findings included the generation of four distinct clusters and three land use type segments that allowed for group comparisons and development of a recommended two-step targeted educational and outreach approach. My dissertation provided theoretical and substantive advances to the fields of adoption research and pollinator conservation from which future research and outreach efforts can grow.

Two Strategies for Improving the Retention Rate of the High-Risk Students in an Instructional Television History Course

Trickel, John A. (John Andrew) 08 1900 (has links)
The problem of this study was to test and compare the impact of two alternative educational treatments on the rate of success among high-risk students enrolled in the United States History telecourse at Richland College, DCCCD during the Spring Semester of 1980. The purposes of the study were to determine whether 1. The rate of success, that is, the proportion of students completing the course with a grade of "C" or higher, would increase among high-risk students in either experimental group; 2. The rate of success would increase among high-risk students with poor reading skills in either experimental group; 3. The rate of success would increase among high-risk students with poor academic motivation for telecourses in either experimental group; 4. The rate of success would increase among high-risk students when related to the demographic variables used as predictors and collected for the students who were in either experimental group; 5. There would be a difference in the effects of experimental treatment I and experimental treatment II in helping students with poor reading skills to complete the course with a grade of "C" or higher; 6. There would be a difference in the effects of experimental treatment I and experimental treatment II in aiding students with different levels and types of motivation to complete the course with a grade of "C" or higher; 7. There would be a difference in the effects of experimental treatment I and experimental treatment II in helping students with the various demographic characteristics used in the prediction equation to complete the course with a grade of "C" or higher.

A Relational Investigation of Political Polarization on Twitter

Walton, Tyler 28 June 2022 (has links)
Over the last several decades there has been a debate among social scientists on whether the United States has become, or is in the process of being, politically polarized. These conversations started with discussion of the “culture wars,” moved to the discussion of selective exposure and media outrage, and currently involve concerns about online radicalization and the spread of online misinformation. Throughout these themes one characteristic has remained constant: a lack of systematic evidence despite anecdotes and feelings of animosity between the two parties. Today researchers are beginning to shift from operationalizing political polarization as growing divides in attitudes towards policy issues towards a focus on political animosity. Scholars attempting to understand the origins of affective polarization have looked at the effect of political identity, out-group perceptions, and the diffusion of moral and emotional content in social media networks. In the current study I build on this literature using a panel of longitudinal data Twitter users to examine whether there is an association between following prominent partisan Twitter accounts and the expression of emotional valence through Tweeting or Retweeting. I take a relational approach to analysis by examining how this relationship varies between networks of Twitter users and under different historical circumstances. I argue that this relational approach is necessary for understanding how political polarization is unfolding in the country and that the lack of a relational approach may explain why political polarization has been downplayed in systematic studies. This study finds that the amount of political polarization on Twitter is dependent both on cultural and historical context. It makes contributions to the literature on political polarization in the United States, research methodology, and has implications for reducing radicalization in online spaces.

Social science students’ perceptions of motivational methods and approaches in science class

Kumlin, Terese January 2017 (has links)
How to motivate students effectively is a question teachers have asked for thousands ofyears. In my teaching program at Malmö University, a variety of teaching methods andapproaches, that also increase motivation, have come into focus. These include:teaching at the right level, using a variety of teaching methods, seeing every student,being enthusiastic about the material, using formative evaluation, connecting lessons tostudents’ everyday life, and adapting classes to students’ interests. The aim of this studyis to find out how secondary students in a social science program perceive teachingmethods and approaches aimed at increasing motivation, and determine which methodsthey perceive as most/least effective. The study used both qualitative and quantitativemethods. 23 upper-secondary students from a class at a school in southern Swedenwere interviewed in four focus groups, where participants were purposefully sampled.10 of these students were also asked to complete a questionnaire ranking the teachingmethods and approaches on a scale of 1-7 (where 1 was most effective at increasingmotivation and 7 least effective), and the mean values of these scores were used in theanalysis. A phenomenological approach and content analysis were used to code andanalyze the data. Students perceived all of the motivational methods to be effective, themost effective being teaching lessons at the right level, followed by using a variety ofteaching methods, with mean values of 1.9 and 3.2, respectively. Adapting lessons tostudents’ interests and connecting them to everyday life were the least effective, withmean values of 5.6 and 5.7, respectively. The categories of teachers having a positiveattitude towards the material and the students, and seeing every student, had the samemean value, 3.8, while formative evaluation had a mean value of 3.9. When trying tomotivate students, it would thus appear more effective to make sure that lessons aretaught at the right level and that teachers vary the lessons, than to adapt lessons tostudents’ interests or connect the material to everyday life. While this was a small studyand the findings cannot be generalized to school populations, they are of high interestfor the researcher.

Practicing Narrative Inquiry II: Making Meanings Move

Bochner, Arthur P., Herrmann, Andrew F. 01 January 2020 (has links)
Narrative inquiry provides an opportunity to humanize the human sciences, placing people, meaning, and personal identity at the center of research, inviting the development of reflexive, relational, dialogic, and interpretive methodologies, and drawing attention to the need to focus not only on the actual but also on the possible and the good. In this chapter, we focus on the intellectual, existential, empirical, and pragmatic development of the turn toward narrative. We trace the rise of narrative inquiry as it evolved in the aftermath of the crisis of representation in the social sciences. The chapter synthesizes the changing methodological orientations of qualitative researchers associated with narrative inquiry as well as their ethical commitments. In the second half of the chapter, our focus shifts to the divergent standpoints of small-story and big-story researchers; the differences between narrative analysis and narratives under analysis; and narrative practices that seek to help people form better relationships, overcome oppressive canonical identities, amplify or reclaim moral agency, and cope better with contingencies and difficulties experienced over the life course. We anticipate that narrative inquiry will continue to situate itself within an intermediate zone between art and science, healing and research, self and others, subjectivity and objectivity, and theories and stories.

Environmental Sustainability Post-COVID-19: Scrutinizing Popular Hypotheses from a Social Science Perspective

Lehmann, Paul, Beck, Silke, de Brito, Mariana Madruga, Gawel, Erik, Groß, Matthias, Haase, Annegret, Lepenies, Robert, Otto, Danny, Schiller, Johannes, Strunz, Sebastian, Thrän, Daniela 09 May 2023 (has links)
There is an increasingly vocal debate on potential long-term changes in environmental sustainability spurred by the global COVID-19 pandemic. This article scrutinizes the social science basis of selected popular hypotheses regarding the nexus between the COVID-19 pandemic and the societal transitions towards environmental sustainability. It presents results that were derived through an interdisciplinary dialogue among social scientists. First, it is confirmed that the COVID-19 crisis has likely created a potential window of opportunity for societal change. Yet, to ensure that societal change is enduring and actually supporting the transition towards environmental sustainability, a clear and well-targeted political framework guiding private investments and behavior is required. Second, it is emphasized that there are important structural differences between the COVID-19 crisis and environmental crises, like time scales. Consequently, many strategies used to address the COVID-19 crisis are hardly suitable for long-term transitions towards environmental sustainability. Third, it is argued that transitions towards environmental sustainability—building both on reducing environmental degradation and building socio-techno-ecological resilience—may create co-benefits in terms of preventing and coping with potential future pandemics. However, research still needs to explore how big these synergies are (and whether trade-offs are also possible), and what type of governance framework they require to materialize.

Kontroversiella ämnen i skolan: didaktik, utmaningar och ansvar : En uppsats om lärares reflektioner kring undervisning om kontroversiella ämnen

Tomley, Zoe, Åberg, John January 2024 (has links)
This study aims to obtain a deeper understanding of upper secondary teachers’ didactical choiceswhen teaching about controversial or sensitive topics; and what the challenges and possibilities arewithin a subject. Controversial and sensitive topics are a part of our everyday life. This study wantstherefore to contribute to the understanding of what can be regarded as controversial or sensitive intoday’s classrooms. To do this we carried out qualitative interviews with semi-structured questionswhich allowed openness in possible follow-up questions. Five civics teachers were interviewed, theirviews recorded, and transcribed. An inductive approach was initially taken when analysing thetranscripts. The three didactical questions what, why, and how, were used as a guide when coding thetranscription. In addition, the data was conceptualised, and themes were identified. These themeswere then used as markers for the result and discussion. The teachers' statements aligned with whatprevious research told us. All teachers interviewed identified at least one controversy, and stated theyfelt positively about their use in schools to aid students in learning. These included recently emergingtopics such as the conflict between Israel and Palestine, national party politics, LGBTQI+, andvictimology. The topics could be used as a tool to give perspective to the information flow in societyand social media surrounding the students. Discussions were also deemed as important whenhandling matters that could cause the class distress. The teachers often used their own or others’ pastexperiences with a subject when handling a topic, often with the students' possible connection andbackground in mind. Even though they found the student’s relation to the subject to be the toughestchallenge and not the topic itself. The teachers' beliefs were that nuancing the subject and discussionsabout controversial and sensitive topics are vital in civic education. / <p>Godkänd 2024-01-19</p>
