The value of Black students knowing about their history has been well-established within the scholarly literature on the teaching and learning of African American history. There is a paucity of empirical studies, however, that examine how exposure to this knowledge informs students’ historical and contemporary understandings. Framed by the theory of collective memory, the purpose of this study was to investigate how two teachers’ contrasting representations of African American history shaped student’ understanding of the Black past and its relationship to the experiences of Black Americans today. To examine this, I conducted an ethnographic study at two school sites that each required students to complete a year-long course on African American history. The participants in this study were two groups of Black high school students and their respective African American history teacher. Analysis of data derived from classroom observations, student and teacher interviews and curricular artifacts (e.g., reading materials, handouts, assessments and writing samples) indicate that teachers’ representations of African American history shaped students’ understandings in distinctive ways. This study contributes to the existing literature by examining students’ interpretations of the Black experience in relation to two teachers’ competing narratives on the meaning and significance of African American history. Findings from this study suggest that we must go beyond advocating for inclusion of African American history curricula and work toward ensuring this is being taught in a way that is relevant and meaningful for students. / Urban Education

This study was undertaken to determine what differences are found among personality characteristics of superior students, in special English classes, who score high on a standardized achievement test and superior students in the same classes who score low on this test. A second dimension of the study was to determine whether the same personality characteristics are evident among superior students in these classes at the eighth, tenth and twelfth grade levels.

In Australia, as in most English-speaking countries, increasing numbers of children with significant hearing loss are being educated in regular classes with the support of itinerant teachers of the deaf, rather than in segregated settings. These students primarily use their amplified residual hearing and communicate orally, and may be functionally defined as hard of hearing. This thesis reports on a study investigating the career development of hard of hearing high school students attending regular Year 10, 11, and 12 classes with itinerant teacher support in the Australian states of Queensland and New South Wales. The students had bilateral sensorineural hearing losses ranging from mild to profound. The study sought to identify and analyse the key factors that influence the career development of this population. The design of the study was informed by Social Cognitive Career Theory (Lent, Brown, & Hackett, 1994), with its emphasis on cognitive variables, personal agency, diversity, and contextual influences, and the developmental theory of Donald Super and its associated concept of career maturity (Super, 1980; Super, Savickas, & Super, 1996). The study also investigated the social participation of hard of hearing adolescents and the relationship among the students' perceptions of their social participation, their social self-concept, and their career decision-making. The research was conducted using a three-phase, mixed methods approach incorporating two major phases, one quantitative and one qualitative, preceded by a minor, preliminary phase. The preliminary, exploratory phase of the study was included in order to guide the design of the survey instrument, and in particular the section covering perceived career barriers, an area not discussed in the literature for this population. Interviews were conducted with four hard of hearing Year 12 school students and four hard of hearing first-year university students who were recent school-leavers. In phase two, sixty-five hard of hearing students were compared with a matched group of normally hearing peers on measures of career maturity, career indecision, perceived career barriers, social participation and three variables associated with Social Cognitive Career Theory: career decision-making self-efficacy, outcome expectations, and goals. In addition, predictors of career maturity were tested for both groups. Phase three comprised the collection and analysis of qualitative data from interviews with a proportion of the survey respondents to explore the quantitative results in greater depth. Twelve students with hearing losses ranging from moderate to profound participated in these interviews. Results of the quantitative analysis indicated that (a) the two groups did not differ on measures of career maturity or social participation, (b) the Social Cognitive Career Theory variables were less predictive of career behaviours for the hard of hearing students than for the normally hearing students, and (c) perceived career barriers related to hearing loss predicted lower scores on the measure of career development attitudes for the hard of hearing students. The quantitative data also showed that survey respondents reported high levels of anticipation of some hearing-related barriers to achieving their educational or career goals, particularly 'people not understanding my hearing loss.' The results of the qualitative analysis extended many of the quantitative findings, yielding information and insights inaccessible through traditional quantitative methods. The qualitative findings revealed ways in which students perceived potential barriers, how they felt about them, and ways in which their perceptions of barriers influenced their career choice and decision-making. In addition, the qualitative findings revealed a complex interaction among students' social participation with their peers, their experiences of other people's negative reactions, their self-consciousness about their hearing loss, their fears about mishearing people, and their career decision-making. In sum, the study identified potential career barriers as a key factor influencing the career development of this group of hard of hearing students, and clarified understanding of the way in which their social self-concept interacted with their career development. The study's findings contribute to current knowledge and understanding of the career development of adolescents with significant hearing loss who attend regular classes with itinerant teacher support in two states of Australia. The thesis discusses implications for theory and for practice that have arisen from the study, and sets out recommendations for ways in which the career development and transition of this population might be improved.

Much of the emphasis on interventions to improve literacy skills has been focused on the primary grade levels. Over the last decade, an increasing amount of research has stressed the need for effective reading interventions for adolescents. However, little research has evaluated effective professional development of secondary teachers in the area of literacy. The current study examines the results of embedded teacher professional development in the form of an intensive summer reading program on student reading achievement. Students reading below the 50th percentile at the end of seventh and ninth grades were identified. The final sample consisted of 92 students who participated in the summer program in its entirety. The program consisted of four weeks (20 sessions) of reading instruction. For the students below grade level, grade equivalent scores significantly increased one-third to one-half of a year. Limitations of the current study are discussed as well as recommendations for future research.

Chemistry is often claimed to be difficult, irrelevant, and uninteresting to school students. Even students who enjoy doing science often have problems seeing themselves as being scientists. This thesis explores and challenges the negative perception of chemistry by investigating upper secondary students’ views on the subject. Based on students’ ideas for improving chemistry education to make the subject more interesting and meaningful, new learning approaches rooted in context-based learning (CBL) are presented. CBL approaches are applied in several countries to enhance interest, de-emphasise rote learning, and improve students’ higher order thinking. Students’ views on upper secondary school chemistry classes in combination with their problem- solving strategies and application of chemistry content knowledge when solving context-based chemistry tasks were investigated using a mixed methods approach. Questionnaire responses, written solutions to chemistry problems, classroom observations, and think-aloud interviews with upper secondary students at the Natural Science Programme and with experts working on context- based chemistry tasks were analysed to obtain a general overview and explore specific issues in detail. Several students were identified who had positive feelings about chemistry, found it interesting, and chose to continue with it beyond the compulsory level, mainly with the aim of future university studies or simply because they enjoyed it. Their suggestions for improving school chemistry by connecting it to everyday life prompted an exploration of CBL approaches. Studies on the cognitive learning outcomes arising from the students’ work on context-based tasks revealed that school chemistry heavily emphasises the recall of memorised facts. However, there is evidence of higher order thinking when students’ problem-solving processes are scaffolded using hints based on the Model of Hierarchical Complexity in Chemistry (MHC-C). In addition, the contextualisation of problems is identified as something that supports learning rather than distracting students. To conclude, the students in this thesis are interested in chemistry and enjoy chemistry education, and their motives for choosing to study chemistry at the post-compulsory level are related to their aspirations; students’ identity formation is important for their choices. Because students are accustomed to recalling facts and solving chemistry problems that have “one single correct answer”, they find more open problems that demand higher order thinking (e.g. knowledge transfer) unfamiliar and complex, suggesting that such processes should be practiced more often in school chemistry. / Kemi är ett skolämne som generellt anses vara både svårt, irrelevant och ointressant för ungdomar. Trots att det ändå finns ungdomar som uppskattar naturvetenskap i allmänhet och kemi i synnerhet, har de ofta problem att se sig själva som naturvetare eller kemister. Denna avhandling undersöker och ifrågasätter den negativa bilden av kemiämnet genom att till en början studera gymnasieelevers syn på kemi. Med utgångspunkt från naturvetarelevers förslag för att förbättra kemiundervisningen och göra ämnet mer intressant och meningsfullt, anknyter avhandlingen därefter till kontextbaserad kemi. Kontextbaserade kurser används i flera länder för att öka elevernas intresse, minska fokuseringen på utantillkunskaper och utveckla elevernas mer avancerade tänkande; med andra ord med målet att uppnå ett meningsfullt lärande. Vid kontextbaserade angreppssätt utgår man från ett sammanhang (kontexten), ofta något personligt eller samhälleligt, som ska vara relevant och intressant. Från dessa kontexter koncentreras därefter undervisningen på de ämneskunskaper man behöver ha för att förstå sammanhanget (s.k. need-to-know). Syftet med avhandlingen är att undersöka naturvetarelevers syn på gymnasiekemin, både deras intresse för ämnet och deras skäl att välja det naturvetenskapliga programmet på gymnasiet, samt elevernas problemlösningsförmåga och användande av ämneskunskaper när de löser kontextbaserade kemiuppgifter. Skälet att studera naturvetarelever på gymnasiet är att dessa elever uppfattas som möjliga framtida naturvetare eftersom de själva har valt naturvetenskaplig inriktning efter den obligatoriska grundskolan. Med hjälp av olika metoder (enkäter, klassrums- observationer, skriftliga lösningar till kemiuppgifter och intervjuer med både elever och experter som löser kemiuppgifter) har analyser genomförts för att dels får en allmän överblick, dels för att utforska specifika delar i detalj både gällande kognitiva och affektiva aspekter av lärande. Resultaten visar att flertalet elever har en positiv inställning till kemi, många tycker att ämnet är intressant och har valt att fortsätta läsa kemi efter den obligatoriska grundskolan främst med målet att studera vidare på universitetsnivå, men också eftersom de specifikt uppskattar kemi. Gymnasieeleverna lyfter fram lärarna som viktiga och lärarstyrda kemilektioner anses positivt, speciellt om lärarna är strukturerade i sin undervisning. Ett vanligt skäl till att välja naturvetenskapsprogrammet är också att man aktivt väljer utbildning med utgångspunkt från vilken skola man vill gå på, något som i denna avhandling tolkas som ett identitetsskapande. Elevernas förslag för att förbättra skolkemin genom att anknyta kemin till vardagen låg till grund för avhandlingens fortsatta inriktning mot kontextbaserade angreppssätt. Analyser av elevernas kognitiva resultat när de löser kontextbaserade kemiuppgifter visar att dagens skolkemi tydligt fokuserar på att memorera faktakunskaper. Eleverna är vana att använda utantillkunskaper när de löser kemiuppgifter eftersom uppgifterna, enligt eleverna, efterfrågar ”det rätta svaret”. Däremot visar studierna också att ett mer avancerat tänkande kan uppnås när elevernas problemlösning stöds av hjälp och ledtrådar som baseras på ett specifikt ramverk, MHC-C (Model of Hierarchical Complexity in Chemistry). När det gäller ämneskunskaperna som krävs för att lösa de kontextbaserade kemiuppgifterna är vissa kemibegrepp viktiga tröskelbegrepp (sk. threshold concepts). Med hjälp av medvetenhet om tröskelbegrepp, som exempelvis polaritet och elektronegativitet för löslighetsuppgifter inom den organiska kemin, kan en större helhetsförståelse för övergripande begrepp (crosscutting disciplinary concepts) som förhållandet mellan kemiska ämnens struktur och egenskaper förhoppningsvis uppnås. När det gäller affektiva resultat anser eleverna att kontexterna i uppgifterna både var intressanta och relevanta, främst när en personlig anknytning var tydlig. Dessutom visade sig kontexterna i uppgifterna vara positiva för lärandet, inte en distraktionsfaktor. Sammanfattningsvis konstateras att svenska elever på naturvetenskaps- programmet är intresserade av kemi och uppskattar kemiundervisningen, speciellt om kemin knyts till vardagen och att lärarna har en tydlig struktur i sin undervisning. Elevernas skäl att välja fortsatta kemistudier efter den obligatoriska grundskolan kan knytas till deras utbildningssträvan men också att elevers identitetsskapande är viktigt för deras gymnasieval. Med hjälp av kontextbaserade angreppssätt kan kemiundervisningen göras mer intressant och relevant samtidigt som elevernas problemlösningsförmåga kan utvecklas. När eleverna möter mer öppna frågor som kräver förklaringar och resonemang är de ovana vid detta och uppfattar uppgifterna komplicerade, samtidigt som de uppskattar denna typ av uppgifter eftersom de uppfattas relevanta och intressanta. Slutsatsen blir att elevernas förmåga till problemlösning av öppna frågor som både kräver faktakunskaper men också förklaringar och resonemang måste tränas oftare inom ramen för skolans kemi för att utveckla elevernas meningsfulla lärande.
