Pose sentences : a new representation for understanding human actions

Ankara : The Department of Computer Engineering and the Institute of Engineering and Science of Bilkent University, 2008.Thesis (Master's) -- Bilkent University, 2008.Includes bibliographical references leaves 55-58.In this thesis we address the problem of human action recognition from video sequences. Our main contribution to the literature is the compact use of poses while representing videos and most importantly considering actions as pose-sentences and exploit string matching approaches for classification. We focus on single actions, where the actor performs one simple action through the video sequence. We represent actions as documents consisting of words, where a word refers to a pose in a frame. We think pose information is a powerful source for describing actions. In search of a robust pose descriptor, we make use of four well-known techniques to extract pose information, Histogram of Oriented Gradients, k-Adjacent Segments, Shape Context and Optical Flow Histograms. To represent actions, first we generate a codebook which will act as a dictionary for our action dataset. Action sequences are then represented using a sequence of pose-words, as posesentences. The similarity between two actions are obtained using string matching techniques. We also apply a bag-of-poses approach for comparison purposes and show the superiority of pose-sentences. We test the efficiency of our method with two widely used benchmark datasets, Weizmann and KTH. We show that pose is indeed very descriptive while representing actions, and without having to examine complex dynamic characteristics of actions, one can apply simple techniques with equally successful results.Hatun, KardelenM.S

Aspect-Oriented Language Mechanisms for Component Binding

Domain Specific Languages (DSLs) are programming languages customized for a problem/solution domain, which allow development of software modules in high-level specifications. Code generation is a common practice for making DSL programs executable: A DSL specification is transformed to a functionally equivalent GPL (general-purpose programing language) representation. Integrating the module generated from a DSL specification to a base system poses a challenge, especially in a case where the DSL and the base system are developed independently. In this paper we describe the problem of integrating domain-specific modules to a system non-intrusively and promote loose coupling between these to allow software evolution. We present our on-going work on aspect-oriented language mechanisms for defining object selectors and object adapters as a solution to this problem

THE COMPARISON BETWEEN THE COGNITIVE AND METACOGNITIVE STRATEGIES USED BY 8TH GRADE STUDENTS TO SOLVE MULTIPLE-CHOICE QUESTIONS ON “PHOTOSYNTHESIS AND RESPIRATION”

The primary aim of this paper is to identify the cognitive and metacognitive strategies used by 8th grade students for solving multiple-choice questions on “Photosynthesis and Respiration” which is among the main subjects of Biology and to compare these strategies according to the type of the school (public school- private school), the level overall grade point averages and the status of answering questions correctly or incorrectly. The study was designed as a qualitative case study. The participants of the study included 8 eighth-grade students in total, who were studying in a private, and in a public school located in the province of Kars. The students who participated in the study were asked to answer the multiple-choice questions on “Photosynthesis and Respiration” during thinking-aloud sessions. To identify whether the strategies used by students in the problem-solving process were cognitive or metacognitive, semi-structured interviews focused on students’ purposes to use cognitive and metacognitive strategies were conducted with students directly after they solve each multiple-choice question. The data collected from the observation records of the processes of multiple-choice question solving, and semi-structured interviews were analysed. The studied data were analysed. The results of the study revealed that 8th grade students who were studying in a private school, whose overall grade point averages was at “Very Good” level, and who answered the multiple-choice questions correctly used a number of cognitive and metacognitive strategies while solving these questions. On the other hand, the students who were studying in a public school, whose overall grade point averages was at “Average” and “Poor” levels , and who answered the questions incorrectly, used a limited range of cognitive and metacognitive strategies.  Article visualizations

ANALYZING STRATEGIES EMPLOYED BY 7TH GRADE STUDENTS IN CORRECTLY AND INCORRECTLY ANSWERING MULTIPLE-CHOICE QUESTIONS ON "REPRODUCTION, GROWTH, AND DEVELOPMENT IN LIVING THINGS"

The objective of this research is to ascertain the cognitive and metacognitive strategies employed by 7th-grade students who correctly answered four multiple-choice questions pertaining to the "Reproduction, Growth, and Development in Living Things" unit, contrasting with those who answered incorrectly. Employing a multiple holistic case study approach within qualitative research methodology, six students from a public secondary school in Kars, Türkiye, participated in the study. These students engaged in solving the aforementioned questions using the think-aloud technique, followed by semi-structured interviews after each question. The entire process, including solving the questions and subsequent interviews, was captured on camera and transcribed for analysis. The transcribed data underwent qualitative analysis using computer-based tools. Results revealed that students who answered correctly employed cognitive strategies such as contextualizing the question, rephrasing it, mental visualization, strategic reading techniques, and increased reading pace, in contrast to those who answered incorrectly. Additionally, those who answered correctly utilized metacognitive strategies including identifying and marking clues, note-taking, option marking, summarization, and option elimination. Notably, students who answered correctly exhibited a broader array of strategies compared to their counterparts who answered incorrectl

Cognitive and metacognitive strategies of 6th-grade students to answer multiple-choice questions on “human body systems”

In this study, cognitive and metacognitive strategies were determined which used by 6th-grade students who answered multiple-choice questions correctly on “Human Body Systems". In determining these strategies, the characteristics of multiple-choice questions (figures, graphs, explanations, etc.) were also considered. Participants of the study included three 6th-grade students, who were studying in a private school located in the province of Kars. The study was designed as a qualitative “case study”. Students whose overall grade point averages were at the “Very Good” level were selected for the study. The students who participated in the study were asked to answer four multiple-choice questions related to four learning areas (circulatory system, respiratory system, digestive system, and excretory system) of the “Human Body Systems” unit of a biology course. The students were asked to answer the multiple-choice questions during the thinking-aloud sessions. Semi-structured interviews were conducted after each question. Students' processes of answering the multiple-choice questions and semi-structured interviews were recorded in video format. The observations from the thinking-aloud sessions, the process of solving the multiple-choice questions, and the semi-structured interviews conducted with students for each question was transcribed. Computer programs for qualitative data analysis were used to analyze data. This study had determined that three students who were studying in the 6th-grade of a private school and whose overall grade averages were at the “Very Good” level, using a large number and diverse range of strategies while answering multiple-choice questions on “Human Body Systems” unit. This study had determined that, students used a diverse range of cognitive strategies such as visualizing, expressing in their own words, analyzing figures, and comparing the answer options to answer the multiple-choice questions. Additionally, metacognitive strategies including re-examining the answer, underlining or circling the clues, marking the explanations in the text of the question, and eliminating incorrect answer options were determined. It was also determined that cognitive and metacognitive strategies, which are important for students to answer multiple-choice questions correctly, vary according to the characteristics of the questions (figures, graphics, explanations, etc.)
