title: Perceptual outcomes as reinforcers

authors: Sumpter, Catherine E.

subjects: psychology

abstract: The paucity of basic behavioral research with humans was highlighted almost 40 years ago (Findley, 1966). A recent search of the basic behavioral research journals by the present authors indicated that this situation remains, with only approximately 15% of the research using human participants. It may seem surprising that so few studies use human participants given the apparent practical advantages of doing so. Human participants are readily available, extensively pre-trained, can use a range of complex apparatus and require no feeding or housing. In reality, however, the use of human participants involves a number of practical difficulties: humans generally will not agree to participate in research involving a large number of sessions or sessions lasting more than two to three hours; it is difficult to gain within-session compliance as a result of the often repetitive and simplistic nature of the tasks; and it is often unclear whether the experimental results are a product of the experimentally-arranged contingencies or the instructions given to the participants. Another difficulty, that which is addressed here, lies in the identification of a suitable experimental outcome that will serve as a reinforcer.

title: Improving the Training of Pre-Service Physics Teachers in Malaysia using Didaktik Analysis

authors: Ishak, Mohd. Zaki

subjects: Physics Education

abstract: The research in this thesis examined the use of a didaktik-based approach to thinking about teaching and learning to the training of pre-service physics teachers in a Malaysian teacher training programme. The process of developing a specific content knowledge (real or true physics) was done through a didaktik analysis of specific physics content, to develop physics content knowledge suitable for schooling, in a particular educational context. Didaktik analysis used as intervention in this study involved: analysing specific physics content as contained in the curriculum specifications and textbooks; analysis of literature on students' alternative conceptions; developing a lesson plan; developing teaching sequences that involve teaching and learning activities, enacting lesson plans and teaching sequence in the microteaching and practicum, and subsequent reflection.
Klafki's (2000) model of didaktik analysis was used as the basis of an intervention employed in a physics teaching methods course (TT4133) at the School of Education, University of Malaysia Sabah (UMS). The intervention consisted of the 14 week course: first seven weeks on theoretical aspects of teaching methods, followed the usual course synopsis, but with modifications in content resulting from didaktik analysis, and the remainder dealt with microteaching; and 8 weeks practicum.  To illustrate the use of didaktik analysis in the training programme, the specific physics content in the areas of force and motion was provided as an example, showing how this was presented to the pre-service physics teachers in the programme. The researcher began with a conceptual analysis of force and motion as presented in the Malaysian secondary physics curriculum specifications and textbooks. This was followed by analysis of the science education literature on students' alternative conceptions involving force and motion, analysis of textbooks presentations of force and motion, and importantly a synopsis of the history of scientific thinking about force and motion. Subsequently, the pre-service teachers were required to prepare lesson plans aided by the researcher based on the above tasks, and this was followed by the development of a teaching sequence which was intended to be implemented in teaching practice with peers (called microteaching in Malaysia), and after further refinement in the practicum in a real classroom (under supervision). 
Participants were third year (15 males and 20 females) and fourth year (18 males and 60 females) pre-service physics teachers in their final year of undergraduate studies. The third year cohort consisted of experienced primary school teachers seeking to become secondary school physics teachers via a three-year conversion course. The fourth year cohort had no prior teaching experience, but held degree-level qualifications in physics. Quantitative data were gathered through two tests of conceptual understanding, The Test of Understanding Graph in Kinematics, TUG-K and The Force and Motion Conceptual Evaluation, FMCE tests, and a purpose-designed instrument the Beliefs About Physics Teaching, BAPT questionnaire. Qualitative data were constructed through the inspection of self-written reports about prior physics learning experiences, inspection of assignments on the didaktik analysis of physics, and individual lesson plans. Video recording and field notes made during observations of microteaching and the practicum, examination of 'written reflections' done in the middle of the methods course, during the practicum, and in the final examinations, and interviews and field notes made by the researcher during meetings with the pre-service physics teachers, completed the data corpus. 
The research findings indicate that generally both cohorts had difficulty understanding kinematics graphs, and weak conceptual understanding of Newtonian concepts. These findings support the findings from the BAPT questionnaire and interviews, which point to perceptions of lack of ability to teach physics, negative attitudes towards teaching specific physics topics at the secondary level, and overall low physics teaching self-efficacy. Overall the findings from the BAPT questionnaire and interviews, before the intervention based on didaktik analysis of physics suggest that these pre-service physics teachers' attitude toward, and beliefs about, physics teaching were based on career interest in teaching, and not on any intrinsic interest in physics or physics teaching as a profession.
After the didaktik analysis intervention it seems that the pre-service physics teachers' teaching practices were shaped by their beliefs about, and experiences of, the physics teaching methods course generally, and the didaktik analysis experience in particular. Overall, it seems this part of methods course helped to improve pre-service physics teachers' understanding of specific physics content, improved their attitude-toward-physics and teaching, helped them to identify problems with students' learning of physics concepts, and helped their teaching practice, subsequently making them more confident about teaching secondary school physics.
The pre-service physics teachers commented on the value of didaktik analysis and this was evident in the microteaching, but not in lesson plans and teaching sequence used in the practicum. It seems this was as a result of a limited amount and a drive by schools to adhere to curriculum specifications. Overall it seems the introduction of didaktik-based analysis intervention increased participants' confidence to teach secondary school physics and that these pre-service physics teachers have gone some way in developing into reflective practitioners in terms of their experiences of: their own secondary physics learning; their physics methods course, both of which led to a better and deeper understanding of physics and methods course content; and the teaching practices in the microteaching and practicum, both of which gave confidence to teach secondary school physics.
Three recommendations are made from this thesis. First, the introduction of a didaktik analysis-based intervention in physics teaching methods courses such as the one in this study, necessitates identification in advance of pre-service physics teachers' attitude toward, and beliefs about physics teaching, along with their attitude-toward-physics and learning, their physics teaching self-efficacy beliefs, and their conceptual understanding of specific physics content. Second, didaktik analysis involving other specific physics content, with other cohorts of pre-service physics teachers, experienced secondary physics teachers, and physicists, is worthy of consideration. Third, the success of the use of a didaktik-based analysis in a physics teaching methods courses requires scaffolding of the teaching sequences employed, and strong support from associate/mentor teachers during the practicum, if didaktik-based teaching is to be realized in the classroom.

title: Teaching Maori in English-medium schools in New Zealand: Teacher responses to aspects of the curriculum guidelines for 'te reo' Maori in English-medium school

authors: Takurua, Nātana

subjects: Maori

abstract: Opinions are divided about how the content of language courses should be specified and whether educational authorities should include specifications/ suggestions about language content in national curriculum documents. Issues associated with language content are, however, not ones that can be avoided, particularly as teachers are expected to prepare students for national examinations at the upper levels of schooling and these examinations are necessarily predicated on general expectations about proficiency achievements and more specific expectations about the types of language with which students will be familiar. In this article, we explore the complex nature of some of the issues involved and the ways in which the New Zealand Ministry of Education has sought/ is seeking to resolve them in the case of the curriculum for Maori in English-medium schools. We also report on the responses of a sample of teachers of Maori in secondary schools in New Zealand to the omission of language examples from the final version of the curriculum guidelines document.
