Le questionnement de la thèse émerge d'un contexte de réforme, en France, de l'enseignement des sciences en lycée qui met au centre du curriculum les démarches d'investigation (DI). Notre étude se situe au moment exact de la décision institutionnelle d'intégrer les DI dans l'enseignement de la chimie en classe de seconde. La mise en place des DI engendre une nouvelle complexité du travail des enseignants qui questionne à la fois leurs pratiques, leurs ressources et leurs connaissances professionnelles. Nous nous sommes proposé de saisir le développement professionnel des professeurs en chimie, particulièrement tourné vers les DI, à partir de leur documentation, c'est-à-dire du travail sur les ressources qu'ils réalisent pour accomplir leur enseignement, particulièrement de la part de ce travail qui prend place au sein de collectifs. L'étude est conduite sur deux études de cas. Dans la première, il s'agit d'un professeur que nous avons suivi, sur deux années consécutives, au sein d'une diversité de communautés professionnelles, parmi lesquelles une communauté associative a pris une place prépondérante. La deuxième étude de cas concerne une enseignante suivie sur une année au sein de communautés ordinaires d'un établissement scolaire. Dans les deux cas, l'étude s'intéresse plus particulièrement à l'enseignement du thème de la quantité de matière en classe de seconde, du fait de l'importance et de la complexité de ce thème d'enseignement au niveau du lycée. La thèse propose des développements théoriques et méthodologiques pour saisir le travail des enseignants, dans ses composantes individuelles et collectives, dans son unité et sa dynamique, en classe comme hors classe. Elle met en évidence le potentiel qu'a le travail collectif pour le développement professionnel des enseignants dans la perspective de DI / The questioning of the thesis emerges from a context of a science education reform in France, that emphasizes the inclusion of inquiry-based science teaching (IBST) into upper secondary school curricula. Our study is situated at the exact moment of the institutional decision to integrate IBST into chemistry teaching at grade 10. The implementation of IBST leads to a new complexity in the work of teachers, which questions their practices, their resources and their professional knowledge. We aim at gaining insight into the chemistry teachers' professional development, particularly with respect to IBST, based on their documentation, i.e. their work on the resources they realize in order to perform their teaching. We focus particularly on the part of this work that takes place within communities. The study was conducted on two case studies. The first one concerns a teacher whom we have followed over two consecutive years within a variety of professional communities, among which one associative community has taken a prominent place. The second case study concerns a teacher followed over one year within ordinary communities of a school. In both cases, the study focuses on the teaching of the amount of substance in grade 10, because of the importance and the complexity of this chemical theme at high school level. The thesis proposes theoretical and methodological developments to understand teachers' work, in its individual and collective components, in its unity and its dynamics, in class and outside the class. It highlights the potential of collective work for teachers' professional development with respect to IBST

Philosophiae Doctor - PhD / Libya, as one of the third world countries, is struggling to address the issue of transformation and various institutional reforms (including the education system). For example, it has been observed that many biology teachers are faced with challenges relating to both subject matter knowledge (SMK) and pedagogical content knowledge (PCK) yet the expectation of the new curriculum is that biology teachers demonstrate professional efficacy in their work regardless of the challenges they face. In light of this, a group of Libyan secondary school biology teachers was investigated in Tripoli through a participatory action research process. The study was underpinned by the Shulman theory of PCK using a mixed-methods design to generate an understanding of the theory of basic knowledge of teaching. This investigation examined the influence of an in-service training programme consisting of three components of PCK namely: teachers‘ subject matter knowledge (SMK); use of instructional strategies; and understanding of learners on a group of Libyan biology teachers‘ instructional practices. On the one hand, the investigation considered their theoretical knowledge, and their experiences during the professional development programme aimed at designing new teaching and learning activities and materials while on the other hand, it considered their practical knowledge in terms of their professional skills or their practical use of what has been learned during their pre-service training as well as what they learned during the professional development programme. Specifically, the study focused on biology teachers from the Hai Alandalus District (Libya). This representation enabled me to unveil the PCK components held to some extent by the Libyan teachers in general. Moreover, the PCK representation has also enabled me to clarify the category of the teachers‘ PCK in the Libyan context especially as their PCK was unknown at the commencement of the study. The findings have shown that the professional development used in the study facilitated the biology teachers‘ ability in several ways such as increased their PCK and SMK; improved their ability to organize activity-based lessons; increased their desire to use a variety of instructional strategies; increased the understanding of their learners‘ needs; improved their awareness that their learners‘ performance is not unrelated to their socio-economic background; and so on. Overall, the findings suggest that designing and implementing new teaching and learning activities and materials based on the teachers‘ knowledge, experiences, and needs, in a workshop context could provide an enabling learning environment for them as well as facilitate their potential to provide a powerful means for increasing their PCK, SMK and understanding their learners. The study also reveals that there is a great necessity for designers to mount professional development programmes that take into consideration the teachers‘ PCK to meaningfully promote their professional development and instructional practices.

Several misconceptions show up when learners answer questions on Chemical Equilibrium during examinations. Literature from other researchers shows similar trend of misconceptions (Johnstone, 2000; Morais, Paiva and Barros, 2007; Adesoji and Babatunde, 2008) for example, ‘apply pressure to the reactants’ (Johnstone, 2000). This shows that Chemistry has no meaning to these learners and they end up with misconceptions as they try to memorise facts in order to pass examinations. Learners are taught before writing these examinations, but how are they taught the concepts of Chemical Equilibrium? A descriptive approach was used on an exploratory survey conducted in Thohoyandou Cluster among Physical Science (Chemistry) FET band Educators. Cluster sampling of 40 educators from 18 randomly sampled schools responded to questionnaires. Five ‘well experienced’ educators who have been producing ‘good’ results at Grade 12 NSC examinations and two Physical Sciences subject advisors were interviewed. Using Spearman Brown Split-Half statistical method a 0,891 reliability coefficient was obtained. Research results show lack or under utilisation of laboratory equipment, teaching strategies which promote rote learning. Lack of confidence of educators due to deficiency in topic content knowledge and pedagogical skills which promote conceptual understanding were identified. Problem of English language leading to communication breakdown between educator-learners and between learner-subject leading to emergency of knowledge gaps in learners. Educators consider professional development through re-training and workshops on subject content matter and teaching strategies as the way forward to improve the quality of teaching. Topic specific PCK focusing on problem-solving strategy was recommended as a means to increasing educators’ efficiency in teaching and enhance learners’ comprehension and achievement in Physical Science. / Science and Technology Education / M.

Abstract in English, Tswana and Northern Sotho / The study aimed to explore teachers’ mathematical knowledge in respect of teaching the concept of fractions to Grade 6 learners. To that end a qualitative study was done, using a case study design. Data were collected through the observation of, and interviews with, three teachers at three schools in the Capricorn South district. Rooted in the theory of constructivism, the study was supplemented by the conceptual framework of mathematical knowledge for teaching (MKT) (Ball et al., 2008) and Shulman’s (1986) notion of pedagogical knowledge for teaching (PCK). The key finding of this investigation revealed that, of the three teachers, two did not develop the concept of fractions for their learners, but merely followed the traditional method of teaching the concept by encouraging their learners to memorise rules without understanding. Only one teacher emphasised an understanding of mathematical concepts. The main observation which the researcher made, was that teachers require a great deal of knowledge and expertise, in carrying out the work of teaching subject matter related to fractions. / Maikaelelo a thutopatlisiso e ne e le go tlhotlhomisa kitso ya dipalo ya barutabana malebana le go ruta barutwana ba Mophato wa 6 mogopolo wa dikarolwana.

This study aimed at exploring the Life Orientation (LO) teachers’ knowledge and teaching of study skills in high schools, Ekudibeng cluster, Gauteng East. The Curriculum and Assessment Policy Statement (CAPS) is the most recent curriculum policy (Department of Basic Education [DBE], 2012) and serves as an action plan to 2030 for the South African education system in order to address some of the origins of underperformance in South African schools (Nicolson, 2013). Life Orientation (LO) can be described as a learning area within the educational context that promotes the holistic development of a child. The educational context refers to all processes at school level involved in training children’s minds and abilities so that they can acquire knowledge and develop skills to succeed in life. Life Orientation integrates subjects, such as life skills, career guidance, health education, physical education, human rights studies and religious education (Pillay, 2012). According to the Life Orientation 2011 CAPS document, Life Orientation teachers are expected to teach study skills to learners starting from grade 10 – 12 (Further Education and Training (FET) Phase (DBE, 2011). Learning or study skills carry over into other areas of life and beyond school. Study skills are therefore critical tools that ensure that learner achievement leads to success. Furthermore, effective study skills need effective interaction between teachers and learners (Gettinger, & Seibert, 2002). The teacher is a social agent and should make study skills accessible through the process of teaching in the classroom. This implies that the teacher is a central tool for equipping the learners with the necessary study skills which can aid in the unlocking of their future potential (Sasikala, 2012). As such, it was considered important to explore the knowledge and skills for teaching LO as well as the challenges faced and their needs for further development. Three schools in Ekudibeng cluster, Gauteng East were purposefully selected for this purpose on the basis of their results in the previous year’ matric exit examinations. Qualitative case studies of the Further Education and Training LO teachers’ experiences at each of these schools were undertaken utilising semi-structured interviews as a data collection tool. The data were analysed via qualitative content analysis techniques. The findings of this study emphasise the need for a focus on study skills teaching and teacher proficiency in the high school education system. The South African Education System role-players need to take LO seriously and have teachers qualified to teach LO, and to meet their needs through study skills training workshops. Comprehensive continuous improvement in learner performance requires a constant determination of trained LO teachers, qualified for the subject and properly equipped with relevant knowledge to cascade it to learners and cooperative community members, where parents are involved/hands on in shaping their children’s’ future. / Psychology of Education / M.

Ce travail constitue un état des lieux de l'enseignement-apprentissage de la stéréochimie, au Bénin, qui caractérise les raisonnements et difficultés des élèves et certaines connaissances professionnelles des enseignants (connaissances du contenu et connaissances pédagogiques du contenu, PCK). Nous analysons des données collectées à partir de questionnaires papier-crayon et d'entretiens avec des élèves, et des enseignants. Les résultats montrent que les élèves utilisent deux types de raisonnements, spatial et analytique, souvent infructueux, pour résoudre les problèmes de stéréochimie. Pour certains, la conduite d'un raisonnement analytique est dû à des difficultés de visualisation mentale. Pour d'autres, elle est provoquée par un manque de connaissances stéréochimiques plutôt qu'une incapacité à manipuler mentalement les représentations sémiotiques. Des raisons de nature différente expliquent les raisonnements spatiaux infructueux : le manque de connaissances géométriques, de capacités de visualisation mentale et de connaissances suffisantes de stéréochimie. Les "connaissances de la compréhension de la stéréochimie par les élèves" et les "connaissances des stratégies d'enseignement" sont reconnues comme des composants clés des PCK, qui se caractérisent donc par la capacité à identifier les difficultés des élèves, à leur attribuer une cause et à proposer une stratégie pertinente pour les surmonter. Les enseignants interrogés n'ont pas atteint ce stade de connaissance et de réflexion sur l'enseignement de la stéréochimie, en raison d'une connaissance réduite des concepts stéréochimiques élémentaires.

The teaching of writing is a central task for teachers of Swedish and it is a complex activity which requires knowledge of different areas such as language, communication, and text. The aim of this licentiate’s dissertation is to investigate when and how the knowledge needed for the teaching of writing is developed in teacher education as well as during the first years of teaching. The study is based on semi-structured qualitative interviews with prospective and novice upper secondary school teachers of Swedish. The data obtained from the interviews were analyzed in two ways. The first analysis focused on the way in which the prospective and novice teachers talked about text, writing, and the teaching of writing. The result shows that, at the beginning of the teacher education, prospective teachers focus on concrete aspects of text – such as syntax, punctuation and spelling – when they speak about text, writing, writing instruction, and assessment of student writings. In other words, they pay special attention to local text levels. At the end of the teacher education  programme, prospective teachers focus on aspects of text structure such as outline, the structure of paragraphs, coherence and cohesion. Certain aspects that the students pay special attention to are mentioned by the novice teachers, but these aspects are not central to them. Instead, novice teachers give special attention to the global text levels such as context, receivers and the purpose of the text, i.e. abstract aspects of text and writing. The pattern discerned shows a development that starts with a focus on the details at a local text level and expands into a more comprehensive view with a focus at a global level. The second analysis concerns the development of the knowledge base for the teaching of writing. This analysis focuses on two of the knowledge categories described by Lee S. Shulman (1986, 1987), namely subject matter knowledge and pedagogical content knowledge (PCK), both of which can be seen as central for the teaching of writing. The knowledge base manifested in the prospective teachers’ utterances mainly consists of subject matter knowledge, whereas the greater part of the knowledge base manifested in the teachers’ utterances consists of pedagogical content knowledge for the teaching of writing. The teachers also manifest a more complex subject matter knowledge and speak about writing instruction in a way which is characterized by conscious choices, reflection and metacognition. The analysis thus shows that the PCK for the teaching of writing is mainly developed in the teaching profession; in other words, after the teacher education programme is finished.
