Literature review shows that, to date, no local based method has been developed for evaluation of optimal wall constructions in a hot and humid climate from architects’ point of view. Hence, this study aims at developing a multi factor optimization model (MFOM) for comparative selection of opaque wall construction in a hot and humid climate based on four main evaluation criterion namely energy efficiency, thermal comfort, moisture control, and cost efficiency. In order to indicate the application of the MFOM, a case study methodology was employed in Kish Island, Iran, which is characterized by a hot and humid climate. Both qualitative and quantitative research methods were employed in the research process including literature and field survey, computer simulation, thermal, moisture and economic analysis finalized with a simple multi attribute rating technique (SMART) grading the outputs for final assessment. According to the results, it can be deducted that the application of the MFOM has the potential to save cost and energy, improve the thermal quality of the indoor environment while predicting the possible construction hazards posed by condensation in hot and humid climates.

Educational research is one of the many fields of knowledge that frequently use case studies as a research method, particularly when applying an interpretive approach. Based on literature reviews and a systematic analysis of current scientific literature, this paper examines the prevalence and characteristics of the case study as a methodology for research on MOOCs. Ninety-two documents were selected from the search results returned by two of the most prestigious scientific databases: Web of Science (WOS) and SCOPUS. Findings showed that (a) even when searching solely for case studies, quantitative research paradigms were more prevalent than interpretive approaches; (b) geographical distribution of these studies was partially biased; (c) case studies were less prevalent in these databases than other empirical investigations on MOOCs; (d) the data collection and data analysis methods most frequently used in the case studies were more aligned with a quantitative approach; and (e) there is still very little instructor-focused research using this methodology. In the light of these findings and their discussion, future directions for research using case study methodology are proposed, given the potential of this method to illustrate certain issues for which other approaches have proved inadequate or insufficient.

ABSTRACT Broccoli has great economic, social, and nutritional importance. Genetic improvements through breeding programs for this species made available cultivars with satisfactory production in hot and humid climates. Two experiments were conducted to evaluate the inflorescence production of broccoli cultivars (Ramoso and Cabeça groups) in the hot and humid climate of Central Amazonia. In experiment 1, Ramoso group cultivars were evaluated (Verão Ramoso Piracicaba, Ramoso Santana, Piracicaba, Piracicaba Precoce, Ramirez F1, Hanabi, Piracicaba Precoce Verão, and Hanapon ). In experiment 2, Cabeça group cultivars were evaluated (Green Storm, Strong, TPX-00925, Salinas F1, Bibou, Domador, Burney, and BRO 68 ). A randomized block experimental design was used, with eight treatments consisted of cultivars, and four replications for each experiment. Quantitative variables were evaluated, including inflorescence fresh and dry weights; and the qualitative variables evaluated showed the occurrence of undesirable characteristics in the inflorescences. Significant differences were found within the Ramoso group cultivars and within the Cabeça group cultivars evaluated. The broccoli cultivars that showed the best inflorescence production in the humid, hot climate of Central Amazonia were Verão Ramoso Piracicaba, Piracicaba Precoce Verão, Ramoso Santana, and Piracicaba Precoce of the Ramoso group; and Green Storm and Burney of the Cabeça group.

Case study researchers have traditionally focused on micro-level analysis of a “bounded” case, yet this approach has come under methodological scrutiny in a world where phenomena are rarely isolated from globalization’s expansive reach. Social science and policy-oriented research in particular are nearly always subject to local and global histories as well as socio-cultural, political, and economic trends. Furthermore, the experience of individuals, organizations, and institutions are often tangled in interconnected webs of influence, such that a case study that does not trace these underlying relationships is likely to be analyzing only the tip of a phenomenological iceberg. Hence critical scholars call for the need to repurpose traditional case study research methods to embrace shifting contextual factors that surround a research project at multiple levels. Comparative case study methods answer this call by making socio-cultural and political analysis an explicit part of the research process. They expand the researcher’s methodological lens by advancing the analysis of processes across three axes: the horizontal (through distinct research sites), the vertical (through scales; e.g., local vs national) and the transversal (over time; e.g., historically). The methodology is particularly useful for social science research and policy studies, where complex interactions between actors and institutions are tied to socio-cultural, political, and economic contexts. Teacher education research is an area where comparative case studies can potentially contribute to policy formulation. Using the example of case study research on teacher education in India, the comparative case study methodology is shown to be an effective research tool. Through insights into the socio-cultural and political context surrounding pedagogical reform, case study research can generate corrective measures to improve policy effectiveness.

The present research aims to determine the effect of films including school and teacher whose learning processes are applied with “Critical Reflection Skills (CRS)” on the critical reflection skills of 4th primary education teachers. In accordance with this purpose, the research was carried out with 73 participants who were the 4th grade students in the Primary Education Teacher Training Department of Gazi Faculty of Education in Gazi University in 2012-2013 education year. The qualitative and quantitative research methods were applied together during the process. Data were collected with “The Critical Reflection Self-assessment Scale (CRSS)” - “Critical Team Application Focus Team Interview Form (CTAFTIF)” and “ Meta Team Observation Form”. During the data collection process, the participants watched the school and teacher containing films at first and then, “Critical Reflection Application (CRA)” adapted from “Critical Reflection Strategy with Teams” was applied. Content analysis was adopted in the analysis of the qualitative data gathered during the research process. In the analysis of the quantitative data, t-test and one-way variance analysis were used.  The results of the conducted research demonstrated that teachers started to generate thinking of critical reflection with school and teacher containing films and the CRA process. It was noticed that statistically a significant difference occurred between the control and experimental groups in terms of critical reflection skills.

Case study methodology has grown in popularity within Health Services Research (HSR). However, its use and merit as a methodology are frequently criticized due to its flexible approach and inconsistent application. Nevertheless, case study methodology is well suited to HSR because it can track and examine complex relationships, contexts, and systems as they evolve. Applied appropriately, it can help generate information on how multiple forms of knowledge come together to inform decision-making within healthcare contexts. In this article, we aim to demystify case study methodology by outlining its philosophical underpinnings and three foundational approaches. We provide literature-based guidance to decision-makers, policy-makers, and health leaders on how to engage in and critically appraise case study design. We advocate that researchers work in collaboration with health leaders to detail their research process with an aim of strengthening the validity and integrity of case study for its continued and advanced use in HSR.

The purpose of this study is to help students who experience mathematical phobia by conducting mathematical therapy. Mathematical therapy was carried out using multimedia "digimonica". This research used quantitative research methods, type of action research. The data sources in this study were 13 students of Class XI of SMA Islam Hasyim Asy'ari Batu who have a mathematical phobia. Data collection method was done by using tests and interviews. The action research process began with the identification of problems, namely the level of students' mathematical phobias. This process was carried out by conducting a pretest, then the researcher conducted a mathematical therapy action with multimedia "digimonica" as an effort to overcome the students' mathematical phobia, then ended with a posttest. Based on the results of the pretest and posttest, the data obtained changes in the level of mathematical phobia of students. In the initial conditions, there were three categories of students who had mathematical phobias (mild, moderate, high), whereas after mathematical therapy, the level of mathematical phobia decreased (mild and moderate). In general, the average student successfully answered more than 2 questions correctly. This proves that therapy using multimedia "digimonica" can help students to reduce the level of mathematical phobia.

A case study is expected to capture the complexity of a single case, which should be a functioning unit, be investigated in its natural context with a multitude of methods, and be contemporary. A case study and, normally, history focus on one case, but simultaneously take account of the context, and so encompass many variables and qualities. When a physical artefact is the case the gap between case study and history tends to diminish and case studies often become more or less historical case studies. Case study methodology also bridges the gap between quantitative and qualitative methods in the social sciences. Still the different concepts of validation in quantitative and qualitative research sometimes create confusion when they are combined, as they often are in case studies. The case might be studied with an intrinsic interest in the case as such, or with an interest in generalising. When a generalisation is based on the deductive principle, the procedure of testing hypothesis is used. A second mode of generalisation is inductive theory-generation, or conceptualisation. The third mode depends on the principle of abduction. Abduction is the process of facing an unexpected fact, applying some rule and, as a result, positing a case that may be. But there are two kinds of abduction: One is when a case is created from a few facts; for instance, historical data or clues. The other is operative when generalisations are made from known cases and applied to an actual problem situation by making appropriate comparisons. This is also called naturalistic generalisation. In a case study, the different modes of generalisation are often combined. The conclusion is that case studies has the potential for further development through the mastery of the combination on different levels of techniques, methodologies, strategies, or theories, like; the combination of case study and history, which is important when the case is an artefact; the combination of differing quality standards in qualitative and quantitative research, which are difficult to codify; and the combination of different modes of generalisation.
