Abstract: Implementation of Multiple-Representation-Based Instructions to Improve the Mastery of Quantum Physics Concepts. This study aimed to design and investigate the role of multiple-representation-based instructions in the improvement of student teachers’ quantum physics mastery. This study used a quasi-experimental control group pretest-posttest design as quantitative part of a mixed-methods study. The subjects were student teachers of physics in the Department of Mathematics and Science Education in a state university in Lampung Province in the 2009-2010 academic year. For assessing the quantum physics mastery, the Quantum Physics Concept Achievement Test (QPCAT) was used. The quantitative analyses were conducted using the Mann Whitney U test. The results showed that multiple-representation-based instructions had a significant effect on student teachers’ quantum physics concept mastery. The results of semi-structured interviews as qualitative part of this study indicated that in the experimental group the students used a variety of representation modes in the learning process and were capable of using the most appropriate one to solve a given quantum physics concept problem. Keywords: quantum physics, multiple representations, concept mastery

This study aimed to explore the effectiveness of a Kinect-based game called Tom Clancy's Ghost Recon: Future Soldier to investigate possible contributions of game-based learning in a virtual language classroom at a state university in Ankara, Turkey. A quasi-experimental design where the treatment group (N= 26) was subjected to kinect-based learning environments, and the control group (N = 26) continued with traditional learning environments was used. All the participants were administered an achievement test as a pre-test, and a post-test. Moreover, the qualitative part of the study included post-study semi-structured interviews with 10 students. The findings showed that there was significant mean difference in student achievement in post-test scores in favor of the experimental group. In addition, the study explored the opinions of the students toward the use of gesture-based computing systems for instructional purposes. The findings suggested some important points to consider while making use of kinect-based games for educational purposes like interaction and learner motivation.

Many recent studies have reported that feedback plays a very important role in students’ learning outcomes. However, currently, feedback has not been utilized by lecturers and students in the learning process effectively. This study aimed to explore the impact of feedback as a soft scaffolding in the ongoing assessment of Quantum Physics class for the students as prospective Physics teachers. A quasi-experimental design non-equivalent pretest-posttest control group was used to examine the effectiveness of feedback based on ongoing assessment. The results of the study revealed that students who received feedback based on metacognitive and social constructivism on studying Quantum Physics showed better average results compared to students who received traditional feedback based on the cognitivism in the form of correction.

This study investigates the effects of problem-based learning (PBL) on students' academic achievements in studying ‘Electrochemistry’ within a course on Analytical Chemistry. The research was of a pretest–posttest control group quasi-experimental design and it was conducted with second year students in the Chemistry Teaching Program at the Faculty of Education at Dokuz Eylul University. The topic was taught with PBL in the experimental group and with expository teaching strategies in the control group. The ‘Chemistry achievement test (CAT)’ was applied as the pre-test and post-test in both groups. Post-test scores from the CAT demonstrated that there was a significant difference between the academic achievements of the two groups in favour of the experimental group (U= 8.500,p< 0.05). After using PBL for a period, eleven open-ended questions related to the topic were asked to both groups. The results of these questions were categorized and the scores obtained from the categories were evaluated using content analysis. The results of the scores obtained from the open-ended questions showed that the students in the experimental group were able to make statements containing fewer misconceptions and also had a better understanding of this topic when compared to the students in the control group (U= 2.500,p< 0.05). The correlation between the scores in the CAT post-test and the scores obtained from the open-ended questions of the experimental and control groups was also examined. The Spearman correlation coefficients were found to be 0.907 and 0.595 for the experimental and the control group, respectively. This finding indicated that there was a positive and very high level of statistically significant correlation between the scores in the CAT post-test and the scores obtained from the open-ended questions of the students in the experimental group. Therefore this finding also supports the conclusion that the students in the experimental group were better able to understand the topic and its structure compared to the students in the control group. At the end of the application, the results of semi-structured interviews carried out showed that students in the experimental group had positive opinions regarding PBL.

<p>A number of writers have recently criticised a perceived narrowness in accountants’ understanding of their profession. In particular, they claim that the predominant focus on shareholders and capital markets may be at the expense of wider public interests that accounting should serve. As accountants engage increasingly with a variety of complex and politically contentious issues, there is cause for concern regarding their capacity to represent and engage with non-financial interests. Some of these concerns are reflected in ongoing debates regarding social and environmental reporting (SER). Accountants are important players in the SER field. They have high-profile roles as self-proclaimed ‘thought leaders’ in areas such as sustainability and integrated reporting, and are increasingly involved in developing SER concepts and practices, discussion papers and best practice guidance. These technologies increasingly rely on, and are legitimised by, their incorporation of a plurality of perspectives. However, both academics and civil society groups have raised concerns that professional accounting bodies are too closely aligned with business interests, and prioritise ‘business case’ (BC) understandings of concepts such as SER, which favour shareholder-oriented perspectives. As in other areas of policy controversy, the capacity to engage with a plurality of perspectives is important because of its impact on, inter alia, the issues that are recognised, how problems are conceived and responded to, and which or whose perspectives are prioritised.  While prior research has explored management and stakeholder perspectives, there has been very little research to date on accountants’ perspectives on SER. Relatedly, relatively little is known about accountants’ abilities to incorporate a multiplicity of views when attempting to engage with complex issues. This study seeks to fill this gap. My research was designed as a quasi-experimental investigation that uses Constructive Conflict Methodology (CCM) and Q methodology (QM) to examine divergent perspectives of SER among three groups of accountants: academics, practitioners, and students. In particular, my research explores the use of CCM as a framework, which when implemented via QM, can help operationalise the theoretical developments of an agonistic approach to critical dialogic accounting (CDA). Drawing on applications of CCM and QM in political theory and policy analysis, my research design is divided into two distinct phases. Phase One focuses on identifying and understanding the range of perspectives among participants regarding SER. Informed by this understanding, Phase Two develops a workshop, the SER Dialogue, to bring together participants who are representative of the diverse perspectives identified.  In Phase One, 34 participants’ perspectives of SER were explored through a mix of semi-structured interviews, questionnaires and QM. The participants evidenced a range of diverse understandings of SER, with three general approaches identified from participants’ Q data: the Critical (F1(CR)), Business Case (F2(BC)) and Incremental Change (F3(INC)) approaches. These general categorisations helped identify differences, inconsistencies and contradictions in the participants’ ideological orientations and illustrated the contested discursive landscape within which SER is conceptualised. Participants’ alignment with each general category also identified possible constraints in their capacity to recognise and understand divergent perspectives. Informed by these insights, Phase Two focused on developing a discursive space for agonistic pluralist engagement (the SER Dialogue) with a group of participants, representing the three diverse perspectives. Ultimately, these participants had both a larger number and magnitude of shifts in their perspective of SER compared to a control group. There was also a general increase in alignment with F1(CR), with many participants demonstrating the development of critically pluralist and reflexive understandings. These findings illustrate the potential for agonistic pluralist engagement to develop accountants’ capacity for pluralist engagement with perspectives surrounding complex and politically contentious issues, while also enabling resistance to the hegemony of BC perspectives within the field of accounting.</p>

A research on the effects of the microteaching Multiple-Representation Lesson Study (MRLS) on pre-service Physics teachers’ critical thinking was conducted using a pre-test-post-test quasi-experimental design. Eighteen fourth year Bachelor of Secondary Education-Physical Science majors participated in the research. The experimental group employed the microteaching MRLS while the control group implemented the Traditional Instructional Planning Approach (TIPA). Data were gathered from multiple sources such as researcher-made written tests, interviews, diaries, and field notes. The Mann-Whitney U test was utilized to ascertain statistical difference between the experimental and the control group. Results revealed significant differences in the scores between the two groups in the overall critical thinking and on its sub-domains. Findings indicate beneficial effects of the microteaching MRLS in developing pre-service teachers’ critical thinking. Keywords: critical thinking, lesson study, multiple representations, physics education, pre-service teachers, science education.
