The relationship between conceptual and procedural knowledge in calculus

Hechter, Janine Esther January 2020 (has links)
Literature describes different stances with respect to conceptual and procedural mathematical knowledge. The concept-driven versus skills-orientated perspectives have led to “math wars” between researchers, while some mathematics education specialists advocate that the five strands of mathematical proficiency should be seen as interconnected. Conceptual knowledge is the knowledge of concepts or principles, and procedural knowledge the knowledge of procedures. Both types of knowledge are critical components of mathematical proficiency. This study used a mixed methods design to analyse the relationship between conceptual and procedural knowledge. The qualitative content analysis investigated relations between procedural and conceptual knowledge within the solutions of 33 calculus items. The analysis included the number of procedural and conceptual steps needed to answer the item, item label and item classification into one of four knowledge classes based on the type and quality of knowledge. The items were included in a data collection instrument used for quantitative analysis. Rasch analysis was performed to measure item difficulty and person proficiency, and describe the underlying cognitive construct between items. The Rasch person–item map confirmed that items were not clustered together per class and that item difficulty was not linked to the number of procedural and/or conceptual steps needed to do the mathematics. Confirmatory factor analysis showed over-correlation between classes and that defined classes cannot be separated, confirming integration of procedural and conceptual cognitive processes. The relationship between procedural and conceptual knowledge within and between items is complex. Findings indicated that item solutions drew on both procedural and conceptual components that cannot be separated. Solutions could follow more than one approach and analyses could differ, since what is conceptual for one student could be procedural for another. Therefore, teaching strategies should navigate between concepts and procedures, methods and representations. / Thesis (PhD)--University of Pretoria, 2020. / Science, Mathematics and Technology Education / PhD / Unrestricted

Climate change: a conflict driver? : A study seeking to understand how state actors in the Arctic Region perceive central aspects of the Environmental Conflict lens.

Kranjc, Aleksander January 2021 (has links)
With parallel increases in both climate change effects and heightening tension between state actors within the Arctic Region, a detrimental outcome is possible if not properly understood. Handling such intricate relationship between climate change, its impacts on human society and conflicts, the Environmental Conflict lens offers a useful perspective that identifies structural conditions and behavioural mechanisms created by climate change, as drivers of conflict. However, a lack within the theoretical understanding of knowing if theorised tenants are present within the perception of actors experiencing empirical reality, does present a problem. Therefore, this research wished to answer how state actors within the Arctic Region describe the theorised structural conditions and behavioural mechanism argued to drive conflict from an Environmental Conflict lens. The study conducted a Qualitative Content Analysis to gain this understanding, focusing on the state actors respective Artic Policy/Strategy, which represented their respective perception. The research was able to identify several instances of the theoretical concepts within each case and to gain an understanding of the state actors’ description derived from the data analysis. The insights gained by the study, call for further theoretical development of Environmental Conflict lens and more proactive research engagements with the Arctic Region.

Informační válka a politika hrozeb: Analýza ruské informační války v Německu a její vnímání německými politiky / Information Warfare and the Politics of Threats: An analysis of Russian Information Warfare on Germany and its Perception by German politicians

Mehrer, Angela January 2020 (has links)
The master thesis analyses the perception of Information Warfare and Russia among German politicians. By using the Qualitative Content Analysis by Schreier, speeches given in the German Bundestag relating to Information Warfare, and Russia were analyzed from January 2015 until December 2018. Using International Relations (IR) theories and political psychological approaches, a theoretical framework was developed in order to determine factors which have an impact on the perception of politicians. The thesis divides this perception into three categories - friend, partner, and threat. Each category is analyzed in depth resulting in support for two of the four hypotheses. The thesis demonstrates that it is not only the political orientation, but also economic interests which determine if a state and its warfare tactics are perceived as a danger. Moreover, the deductive part of the analysis reveals that Russia's behavior which can be perceived as aggressive, irrational, and power-seeking, also determines whether the regime is perceived as threatening. Information Warfare per se is no issue of concern in the Bundestag. However, information warfare tactics such as disinformation campaigns, the spread of fake news and propaganda, and Russia's meddling in western politics are perceived as a danger to...

Autoritářské aliance - pochopení vztahu mezi Ruskem a Tureckem: Zkoumání souvislosti mezi politickým režimem a mírem / Authoritarian Alliances - Understanding the Russia-Turkey Relationship: Exploring the Link Between Political Regime and Peace

Merkel, Lea Judith January 2020 (has links)
The thesis analyses Turkey's and Russia's foreign relations with each other based on the theoretical premise that democratic peace can explain similar behaviour among authoritarian regimes as well. The thesis explores Russia's and Turkey's distinct forms or authoritarianism, before employing a detailed qualitative content analysis on official documents from Russia's and Turkey's presidents and foreign ministries. The readers will attain a broader understanding of democratic theory and the link between political regimes and peaceful relations.

Let it Go: A Critical Comparative Analysis of the Modern-Day Female Protagonist Based on Disney's Frozen and Frozen II

Hannah G Scheffer-Wentz (9764021) 16 December 2020 (has links)
<p>This thesis is a comparative content analysis of the modern-day female protagonists represented in Disney’s newest and highest grossing film series, Frozen and Frozen II. As one of the few major media companies that have captivated a global audience, Disney has supplied fantasy princess narratives for over 80 years. With the new addition of Disney+, classic and modern princess films alike are now available for instant streaming. As the sample represents the newest films in the post-transitional wave of the Disney Princess line, this study aims to reveal what messages are being projected to young, impressionable audiences around the world. Between the third wave of feminism and rising conversations of gender roles and communication, Disney Princess films in particular have been the subject of many conversations and criticisms. Using content analysis methodology with each film, the data identifies gender roles, conflict resolution, and common themes between the six main characters: Elsa, Anna, Kristoff, Olaf, the King, and the Queen.</p>

A Content Analysis of the Journal of Adolescent Health: Using Past Literature to Guide Healthcare Research of US Ethnic Minority Adolescents

Handy, Kate Amanda 01 July 2018 (has links)
Ethnic minority research in the U.S. is important given the increase in ethnic minority populations, particularly within the adolescent population. Content analyses are useful in guiding researchers as they document representation and progress of research on ethnic minorities within many fields, including healthcare. The Journal of Adolescent Health was coded for the following variables: ethnic minority focus, article topic, article funding by topic, geographic location of sample, and inclusion of measures (ethnic identity and acculturation). The results indicated that the percentage of published articles focused on each specific ethnic minority group were lower than the current U. S. percentages, including Latinos (3.7% of the published articles versus 17.8% of the U. S. population), African Americans (5.8% versus 13.3%), Asian Americans (0.6% versus 5.9%) and Native Americans (0.5% versus 1.3%). Over the 28-year period, the Journal of Adolescent Health increased in the number of ethnic minority focused articles published per year, but in relation to the yearly article output decreased in actual percentage of ethnic minority focused articles per year (5.7% decrease in percentage of ethnic minority focused articles published).

U.S. Racial/Ethnic/Cultural Groups in Counseling Psychology Literature: A Content Analysis

Hawkins, Jared Mark 01 July 2018 (has links)
Research on ethnic/racial/cultural (REC) groups can contribute to reducing mental health risks and treatment disparities among REC minorities. Content analysis is a way to measure the quantity and quality of REC-focused research within a given field. For this study, counseling psychology was chosen for its leadership in multicultural and social justice issues. Three journals (Journal of Counseling Psychology, The Counseling Psychologist, and Journal of Counseling & Development) were coded for several variables, including REC-minority focus, article topic, geographic location of sample, urban/rural setting of sample, and inclusion of ethnic identity and acculturation measures. The results showed that 490 (21.3%) of the articles were coded as REC-focused. Of the REC-focused articles, 107 (21.8%) articles were focused on African Americans, 99 (20.2%) were focused on Asian Americans, 74 (16.9%) were focused on Latinos, and 17 (3.5%) were focused on Native Americans. Additionally, 194 (39.5%) were coded as "Other." REC minorities, especially Latinos and African Americans, were found to be under-represented relative to their populations in the U.S. The results indicate a need for improved reporting practices and increased focus on REC minorities in counseling psychology research.

Health Communication via Social Media: How Pharmaceutical Companies are using Instagram for Corporate Social Responsibility

Akinboboye, Abisoluwa 01 May 2020 (has links)
This study examines the depth of audience engagement with six dimensions of Corporate Social Responsibility (CSR) via the Instagram platforms of pharmaceutical companies. Recent research on the relationship between CSR and health communication has established a robust link between both variables but created a gap on the level of audience engagement. Drawing on Voluntary Disclosure, Agenda Setting and Media System Dependency theories, this study finds that voluntary communication of CSR strategies has the maximum potential to set the agenda for audience engagement on social media. The remodeled digitization of the media has increased the level of media dependency making social media a tool to be leveraged for effective health communication. The results revealed that Community Volunteering had the strongest impact on total audience engagement and revealed that engagement is higher with image posts than video posts. This study is important for the burgeoning field of CSR in the healthcare industry.

Kvinnor i kriminella gäng : En kvalitativ textanalys av medias beskrivning av kvinnors roller i kriminella gäng

Nordberg, Denice, Genberg, Jenni January 2020 (has links)
This study researches the mass media description of women’s roles in criminal gangs as well as the contributing factors portrayed by the media for women and their involvement in the criminal gangs. We believe that this is an important subject to highlight, mainly due to the fact that the information available today is more often than not about the men whereas the women and their situation are portrayed and written about far less frequently. By using a qualitative text analysis we want to bring light to the image portrayed by the women and thereby contribute with an increase to understanding the specific terms these women face in the given contexts with the hope that the result will contribute to an increase in the knowledge of crime fighting and law enforcement. The empirical material consists of 20 articles from the following newspaper: Aftonbladet, Expressen, Svenska Dagbladet and Göteborgs-Posten, which have been analyzed through a content analysis. The results show that women in the gang have a far more active role than previously reported and that the activity in the gangs has increased as well. This falls in line with previous international research where women’s roles have been highlighted as predominantly active in organised crime. Furthermore, the women’s role in media is often mentioned as supportive or even being victims of the men in the gangs. A common explanation that is given is that the women join the gang due to societal factors such as the women feeling let down by their society. Social relations such as family and boyfriends that are part of criminal gangs and that might influence the women are also brought up as possible causes. More unusual factors that draw the women to gangs regard financial incentives such as the dream of making a great deal of money, longing for a feeling of safety or to simply experience excitement.

Representation of U.S. Minority Groups in the Marriage and Family Therapy Literature Over an 18-Year Period: A Content Analysis

Osmond, Kensington 30 July 2020 (has links)
Research relevant to the unique needs and experiences of racial/ethnic/cultural (REC) minority groups in social science literature is essential to the work of policymakers and clinical practitioners. However, the social sciences have traditionally failed to publish a sufficient number of articles that address these needs and experiences or even adequately report the racial and ethnic makeup of their samples. The purpose of this study is to provide an updated look at Marriage and Family Therapy (MFT) literature and how often sample participants’ ethnicity is reported, how frequently studies focus on ethnic issues or specific REC minority groups, which REC minority groups and topics receive the most attention in minority-focused studies, which REC minority groups and topics receive the most attention in funded studies, and how these trends have changed over time. Specifically, five journals (American Journal of Family Therapy, Family Process, Journal of Family Therapy, Journal of Marital and Family Therapy, and Contemporary Family Therapy) were selected for inclusion in the analysis and were examined inclusively from 2000-2017. Results and suggestions for future research are discussed.
