Educational reforms, cultural clashes and classroom practices

This article presents an ongoing study of educational policy enactment in Singapore lower primary English classrooms. It explores how teachers react to and interpret educational reforms in their classroom practices against a backdrop ofvtraditional cultural values. Using a prescribed coding scheme, the article presents the instructional organisational patterns and participation structures of the lessons.Through a systematic analysis of the enacted curricula, the paper examines classroom practices as well as teaching and learning activities in Primary 1 (7–8 years) and Primary 2 (8–9 years) English lessons in Singapore. The results suggest that there are cultural clashes between major educational reforms which emphasise independent/critical thinking and ‘Asian values’ which promote respect for authority and conformity.

Correlates of early reading comprehension skills: a componential analysis

This study had three main aims. First, we examined to what extent listening comprehension, vocabulary, grammatical skills and verbal short-term memory (VSTM) assessed prior to formal reading instruction explained individual differences in early reading comprehension levels. Second, we examined to what extent the three common component skills, namely vocabulary, grammar and VSTM explained the relationship between kindergarten listening comprehension and early reading comprehension levels. Third, we examined the relative contributions of word-reading and listening comprehension skills to early reading comprehension in Turkish. For this purpose, 56 Turkish-speaking children were followed from kindergarten (mean age = 67.7 months) into Grade 2 (mean age = 90.6 months). The relative role of kindergarten listening comprehension, vocabulary, VSTM and grammatical skills in later reading comprehension tended to vary across time, and they partly explained the relationship between listening comprehension and reading comprehension. Finally, as anticipated, listening comprehension, rather than word-reading , was found to play a more powerful role in children’s reading comprehension levels even during the early primary grades. These results contradicted those reported in English and can be explained by the rapid development of accurate word-reading skills due to the consistency of the grapheme–phoneme relationships of the Turkish orthography.

Why Implementing History and Philosophy in School Science Education is a Challenge: An Analysis of Obstacles

Teaching and learning with history and philosophy of science (HPS) has been, and continues to be, supported by science educators. While science education standards documents in many countries also stress the importance of teaching and learning with HPS, the approach still suffers from ineffective implementation in school science teaching. In order to better understand this problem, an analysis of the obstacles of implementing HPS into classrooms was undertaken. The obstacles taken into account were structured in four groups: 1. culture of teaching physics, 2. teachers` skills, epistemological and didactical attitudes and beliefs, 3. institutional framework of science teaching, and 4. textbooks as fundamental didactical support. Implications for more effective implementation of HPS are presented, taking the social nature of educational systems into account.

Contemporary Approaches to Translation in the Classroom : A study of students' Attitudes and Strategies

The purpose of this study is to explore the strategies and attitudes of students towards translation in the context of language learning. The informants come from two different classes at an Upper Secondary vocational program. The study was born from the backdrop of discussions among some English teachers representing different theories on translation and language learning, meeting students endeavoring in language learning beyond the confinement of the classroom and personal experiences of translation in language learning. The curriculum and course plan for English at the vocational program emphasize two things of particular interest to our study; integration of the program outcomes and vocational language into the English course - so called meshed learning – and student awareness of their own learning processes. A background is presented of different contrasting methods in translation and language learning that is relevant to our discussion. However, focus is given to contemporary research on reforms within the Comparative Theory, as expressed in Translation in Language and Teaching (TILT), Contrastive Analysis and “The Third Space”. The results of the students’ reflections are presented as attempts to translate two different texts; one lyric and one technical vocational text. The results show a pragmatic attitude among the students toward tools like dictionaries or Google Translate, but also a critical awareness about their use and limits. They appear to prefer the use of first language to the target language when discussing the correct translation as they sought accuracy over meaning. Translation for them was a natural and problem-solving event worth a rightful place in language teaching.

Acceptability of home-assessment post medical abortion and medical abortion in a low-resource setting in Rajasthan, India : Secondary outcome analysis of a non-inferiority randomized controlled trial

Background: Studies evaluating acceptability of simplified follow-up after medical abortion have focused on high-resource or urban settings where telephones, road connections, and modes of transport are available and where women have formal education. Objective: To investigate women's acceptability of home-assessment of abortion and whether acceptability of medical abortion differs by in-clinic or home-assessment of abortion outcome in a low-resource setting in India. Design: Secondary outcome of a randomised, controlled, non-inferiority trial. Setting Outpatient primary health care clinics in rural and urban Rajasthan, India. Population: Women were eligible if they sought abortion with a gestation up to 9 weeks, lived within defined study area and agreed to follow-up. Women were ineligible if they had known contraindications to medical abortion, haemoglobin < 85mg/l and were below 18 years. Methods: Abortion outcome assessment through routine clinic follow-up by a doctor was compared with home-assessment using a low-sensitivity pregnancy test and a pictorial instruction sheet. A computerized random number generator generated the randomisation sequence (1: 1) in blocks of six. Research assistants randomly allocated eligible women who opted for medical abortion (mifepristone and misoprostol), using opaque sealed envelopes. Blinding during outcome assessment was not possible. Main outcome measures: Women's acceptability of home-assessment was measured as future preference of follow-up. Overall satisfaction, expectations, and comparison with previous abortion experiences were compared between study groups. Results: 731 women were randomized to the clinic follow-up group (n = 353) or home-assessment group (n = 378). 623 (85%) women were successfully followed up, of those 597 (96%) were satisfied and 592 (95%) found the abortion better or as expected, with no difference between study groups. The majority, 355 (57%) women, preferred home-assessment in the event of a future abortion. Significantly more women, 284 (82%), in the home-assessment group preferred home-assessment in the future, as compared with 188 (70%) of women in the clinic follow-up group, who preferred clinic follow-up in the future (p < 0.001). Conclusion: Home-assessment is highly acceptable among women in low-resource, and rural, settings. The choice to follow-up an early medical abortion according to women's preference should be offered to foster women's reproductive autonomy.

Social Media, Privacy, and the Academic Classroom

We live in a world full of social media and portable technology that allows for the effortless access to, and sharing of, information. While this constant connection can be viewed as a benefit by some, there have been recent, sometimes embarrassing, instances throughout the world that show just how quickly any expectation of privacy can be destroyed. From pictures of poorly dressed shoppers at a grocery store to customers recording interactions with their servers at restaurants, the internet is full of media (all with the potential to go viral) created and posted without consent of all parties captured. This risk to privacy is not just limited to retail and restaurants, as being in any situation amongst people puts you at risk, including being in an academic classroom. Anyone providing in-class instruction, be they professor or librarian, can be at risk for this type of violation of privacy. In addition, the students in the class are also at risk for being unwittingly captured by their classmates. To combat this, colleges and universities are providing recommendations to faculty regarding this issue, such as including suggested syllabus statements about classroom recording by students. In some instances, colleges and universities have instituted formal policies with strict penalties for violators. An overview of current privacy law as it relates to an academic setting is discussed as well as recent, newsworthy instances of student recording in the classroom and the resulting controversies. Additionally, there is a discussion highlighting various recommendations and formal policies that have been issued and adopted by colleges and universities around the country. Finally, advice is offered about what librarians can do to educate students, faculty, and staff about the privacy rights of others and the potential harm that could come from posting to social media and the open web images and video of others without their consent.

Context-sensitive analysis of obfuscated x86 executables

A method for context-sensitive analysis of binaries that may have obfuscated procedure call and return operations is presented. Such binaries may use operators to directly manipulate stack instead of using native call and ret instructions to achieve equivalent behavior. Since definition of context-sensitivity and algorithms for context-sensitive analysis have thus far been based on the specific semantics associated to procedure call and return operations, classic interprocedural analyses cannot be used reliably for analyzing programs in which these operations cannot be discerned. A new notion of context-sensitivity is introduced that is based on the state of the stack at any instruction. While changes in 'calling'-context are associated with transfer of control, and hence can be reasoned in terms of paths in an interprocedural control flow graph (ICFG), the same is not true of changes in 'stack'-context. An abstract interpretation based framework is developed to reason about stack-contexts and to derive analogues of call-strings based methods for the context-sensitive analysis using stack-context. The method presented is used to create a context-sensitive version of Venable et al.'s algorithm for detecting obfuscated calls. Experimental results show that the context-sensitive version of the algorithm generates more precise results and is also computationally more efficient than its context-insensitive counterpart.

Classroom discipline, classroom environment and student performance in Chile

This paper assesses the extent to which teachers’ actions in the classroom influence the school environment. The assessment is based on a statistical analysis of videotaped classroom observations of 51,329 teachers. The classroom environment was found to have a significant influence on students’ performance. More specifically, the teacher’s ability to handle the class as a group is consistently more significant than other measures of class environment. It was also founds that the overall school environment is a better predictor of students’ test results than the environment in the classrooms of the students whose test results are being reported. This suggests that the most effective course of action would be to improve the overall school environment, although individual teachers have less control over this factor.

Análise de metodologia baseada no sistema de ensino individualizado de Keller aplicada em um curso introdutório de eletromagnetismo

Uma das metodologias de ensino individualizado mais usadas e documentadas na década de 70 foi o Sistema Personalizado de Instrução (SPI) de Fred Keller. Diversas pesquisas sobre essa metodologia foram publicadas, as quais proveram extensa evidência empírica de seus resultados positivos. Apesar disso, a aplicação desse sistema de ensino entrou em declínio a partir da década de 80. Dentre as razões para tal declínio, podemos destacar o maior esforço requerido para a elaboração de cursos utilizando essa metodologia e para o provimento de feedback sistemático ao desempenho dos alunos, assim como o surgimento de críticas a ela devido à abordagem comportamentalista de Keller. Mesmo sendo fundamentais para a aprendizagem, o estímulo à postura ativa do estudante, o respeito ao ritmo individual de aprendizagem, as avaliações formativas e o provimento de feedback sistemático ao aluno continuam frequentemente fora das salas de aula. Uma estratégia para suprir tais carências é o ensino individualizado. Neste trabalho, propomos várias modificações ao SPI de Keller visando uma metodologia viável de ser empregada em um curso introdutório de eletromagnetismo para estudantes de física da Universidade Federal do Pará. Dentre estas modificações, destacamos: (i) o emprego de avaliações semanais, e não em todas as aulas; (ii) a correção das avaliações e provisão de feedback feitas pelo professor, e não pelos monitores; e (iii) a manutenção parcial de aulas expositivas. Com base em uma avaliação incluindo parâmetros mensuráveis, obtivemos indícios de que, apesar das modificações introduzidas, a aplicação dessa metodologia permitiu obter vários dos resultados positivos comuns na aplicação do SPI de Keller.

Emergência de comportamentos autônomos na aprendizagem da língua estrangeira a partir da interface da consciência linguageira e da motivação

Esta pesquisa situa-se entre os estudos da Consciência Linguageira e a formação de comportamentos autônomos com influência do fator motivacional em aprendentes do Inglês como língua estrangeira. Considerando a relevância da explicitude dos insumos complexos e da Consciência Linguageira na instrução, observei que, ao utilizar esses princípios, o docente pode favorecer em seus aprendentes a formação de comportamentos que os levem a um maior controle de sua própria aprendizagem. Desta forma, o presente estudo tem como objetivos verificar a correlação entre Consciência Linguageira, autonomização e motivação como aspecto subliminar. O embasamento teórico deste estudo respalda-se essencialmente nas contribuições de Little (1997), Flavell (1976), Donmall (1991), Hawkings (2001), James; Garret (1991), Benson (2001), Rutherford (1987) e Van Lier (1991). Concomitantemente à investigação bibliográfica foi desenvolvida uma pesquisa - ação a fim de compreender o processo de apropriação do insumo pelo aprendente adulto, formulando hipóteses e valorizando o contexto dinâmico da sala de aula para intervir na melhoria da aprendizagem. A observação e a coleta de dados ocorreram em uma turma do 6º nível de língua inglesa, dos Cursos Livres de Línguas Estrangeiras, da Universidade Federal do Pará. Os dados procedentes das entrevistas, questionários, observações e atividades de foco na forma demonstraram que diante de situações em que o insumo linguístico apresentava maior complexidade, as produções orais e escritas ficavam comprometidas e havia menor participação dos aprendentes nas atividades de conversação. Observei ainda, que as atividades de Foco na Forma, a explicitude e as reflexões conduzidas por meio de metalinguagem aproximaram os alunos da solução de dificuldades ante os insumos complexos, e os motivaram a buscar, autonomamente, diferentes alternativas de aprendizagem. Os dados foram cruzados para as análises a respeito das implicações da Consciência Linguageira no desenvolvimento de comportamentos autônomos e da motivação sobre o desempenho dos aprendentes, permitindo uma reflexão relativa ao tema e aos insights significativos para a solução de problemas oriundos da imprevisibilidade do contexto em sala de aula.
