Enhancing Teachers' Knowledge For Using Multiple Representations In Teaching Chemistry In Nigerian Senior Secondary Schools, Bolanle Omotoke Olaleye Jan 2012

Enhancing Teachers' Knowledge For Using Multiple Representations In Teaching Chemistry In Nigerian Senior Secondary Schools, Bolanle Omotoke Olaleye

Theses: Doctorates and Masters

The quality of the teaching and learning of chemistry in Nigeria is of great concern to parents, teachers, and students and has been tied to various factors such as a lack of teaching resources, learning materials and well qualified teachers, large class sizes and poor funding. This resulted in poor student performance and lack of interest in chemistry. Also, learning chemistry concepts tends to be by rote and memorising of content, and as such, students do not perceive learning chemistry as relevant to their lives. These issues motivated the Researcher to explore how teaching and learning of chemistry could be …


Alignment Of Intended Learning Outcomes, Curriculum And Assessment In A Middle School Science Program, Reid J. Smith Jan 2012

Alignment Of Intended Learning Outcomes, Curriculum And Assessment In A Middle School Science Program, Reid J. Smith

Theses: Doctorates and Masters

This study focused on the intended learning outcomes, curriculum and assessment in the science curriculum offered at a regional independent Middle School in the state of Victoria, Australia. In-school assessment has indicated that the current science curriculum of this Middle School may not develop students' skills in scientific literacy as effectively as intended. One hypothesis to explain this deficit is that there is a misalignment of intended outcomes, curriculum materials and assessment. This study aimed to determine the extent to which the intended curriculum and assessment in this Victorian middle years' science program is aligned to its stated goals and …


An Investigation Of The Factors That Influence The Career Aspirations Of Year 12 Science Students, Christina R. Holly Jan 2005

An Investigation Of The Factors That Influence The Career Aspirations Of Year 12 Science Students, Christina R. Holly

Theses: Doctorates and Masters

What has become apparent in recent years is the lack of upper secondary students choosing science related subjects in their final years of schooling. Even of those students who choose science subjects to study in Years 11 and 12 in Australia, many tend to choose non-science pathways for tertiary education options (department of Education, Science and Training, 2003). This is worrying trend, given the numbers of science professionals and teachers required in the new age of technology. By investigating a sample of Western Australian Year 12 students that study any science related subjects, it is expected that there may be …


Student Beliefs About Learning In Religion And Science In Catholic Schools, Philip F. Cox Jan 2004

Student Beliefs About Learning In Religion And Science In Catholic Schools, Philip F. Cox

Theses: Doctorates and Masters

The focus of this study is the impact of student perception of the validity of content on student learning. It is proposed that, if the content of a subject is perceived by students as being different to the content of another subject, a result of this perceived difference is that students will treat their learning in these subjects differently. To test this proposal, student beliefs about items from the content of the religious education course are compared with student responses to items of content of their science course. A sample of 1418, year 11 students from nine co-educational Catholic secondary …

Facilitating Teacher Professional Learning : Analysing The Impact Of An Australian Professional Learning Model In Secondary Science, Rachel Sheffield

Theses: Doctorates and Masters

In education, innovations are frequently introduced to promote changes to the curriculum, teachers' practice, and the classroom environment, however, these initiatives are often implemented without sufficient evaluation to monitor their impact and effectiveness in bringing about the desired changes. This thesis analyses the impact of a teacher professional learning program on lower secondary science teachers' practice. It examines the relationship between teachers' concerns about the strategies incorporated in the Collaborative Australian Secondary Science Program (CASSP) and teachers' ability to understand the strategies, on their ability to utilise those strategies in the classroom. It also seeks to determine teachers' beliefs about …

Secondary Students Beliefs About, Understandings Of, And Intentions To Act Regarding The Greenhouse Effect, Premnadh M. Kurup

Theses: Doctorates and Masters

The greenhouse effect (GHE) is a concern to everyone on this planet. To understand the GHE, students and citizens need an understanding of the chemical processes underlying this environmental phenomenon. Citizens need to be scientifically literate in relation to this phenomenon in order to participate in democratic decision-making and to take appropriate actions in their daily lives. As the GHE is a global issue it will require collective and individual actions to prepare for the likely climatic changes and to reduce the further impact of the GHE. This study focused on high school students' beliefs about, understandings of the GHE …

The resources included background information for the teachers and suggested activities, demonstrations, analogies and focus questions …


Secondary Students' Skills Of Measuring Liquid Volume And Understanding Of Uncertainty Of Data, Wayne M. Keady Jan 1999

Secondary Students' Skills Of Measuring Liquid Volume And Understanding Of Uncertainty Of Data, Wayne M. Keady

Theses: Doctorates and Masters

This research is a detailed study of students' skills of measuring liquid volume, the decisions they make when planning to collect data and whilst collecting data, and the extent to which they understand the uncertainty associated with the data they collected. These skills and understandings are at the heart of scientific literacy (Duggan & Gall, 1996a). The introduction of the Working Scientifically strand in the Australian national curriculum framework and profile of learning outcome statements for science (Australian Education Council, 1994) illustrates the increased emphasis placed in curriculum documents on investigation skills and scientific literacy. The profile of outcome statements …

The Effect Of A Vee-Mapping Strategy On Students' Perceptions Of Laboratory Activities, Sonia J. Hueppauff Jan 1990

The Effect Of A Vee-Mapping Strategy On Students' Perceptions Of Laboratory Activities, Sonia J. Hueppauff

Theses : Honours

Practical work is considered important for learning science, by teachers and science educators. This acceptance though, has been reported as based on intuition rather than evidence (Atkinson & White, 1961). A significant proportion of class time is occupied with doing practical work. It is evident that in a majority of situations, students commence laboratory activities unsure of their aim, the procedure they are going to carry out, or that experimentation is a way of forming knowledge (Moreira, I 960; Novak & Gowin, I 964). Vee-maps (Novak & Gowin, 1 964) are one way of making laboratory work more meaningful. That …
