Current engineering courses are not structured to develop real problem-solving skills in their students. They rely on a bottom-up approach to learning, where the first three years is spend mostly on theory, with almost no practice at problem definition. Instead, the students spend most of their time solving carefully designed exercises. Real-world problems are not as neatly packaged as these exercises, and, as a consequence, graduate engineers often lack the problem-definition and problem-recognition skills that are essential if the theory they have learned is to be useful to them. On the contrary, a problem-oriented course requires the students to develop those problem recognition skills. It also is intended to develop student-directed learning, and group and communication skills. A problem-oriented approach was used in 1991 in two second-year courses in civil engineering—surveying and computing. The courses were well received by the students, and the average exam result for surveying showed a noticeable improvement, while the average exam result for computing showed a marginal improvement. (There were, however, other encouraging signs in the computing course.) The author believes that the difference in response between the two subjects is due to the difference between working in groups and working individually, and a course change for the computing subject for 1992 is proposed. 相似文献

This study seeks to analyze how students apply a mathematical modeling skill that was previously learned by solving standard word problems to the solution of word problems with nonstandard contexts. During the course of an experiment involving 106 freshmen, we assessed how well they were able to transfer the mathematical modeling skill that is used to solve standard problems to the solution of nonstandard ones that had an analogous structure. The results of our research show that students had varying degrees of success applying the different stages of modeling depending on whether they were solving a familiar problem (involving near transfer) or one that had an unfamiliar context (involving far transfer): in cases of near transfer, students applied the template formally even though it did not align with the text of the new word problem, which complicated further interpretation. In cases of far transfer, students chose to solve the problem by using an ordinary method of selecting a solution by trial and error in preference to the use of modeling. Thus, the application of the modeling skill as a multistage process is complicated when solving nonstandard problems involving either near or far transfer. 相似文献

Abstraction is a major concept in computer science and serves as a powerful tool in software development. Pattern-oriented instruction (POI) is a pedagogical approach that incorporates patterns in an introductory computer science course in order to structure the learning of algorithmic problem solving. This paper examines abstraction processes in the course of solving an algorithmic problem and highlights three distinct, although interrelated, facets of abstraction: pattern recognition, black-boxing, and structure identification. A study that examined the influence of the POI approach on students' abstraction skills is described; students who learned according to the POI approach were compared with students who learned in a traditional manner with regard to analogical reasoning and problem decomposition and solution, as well as verbal expression. The three facets of abstraction were used to analyze students' abstraction skills and their competency in algorithmic problem solving. 相似文献

This article describes the design, evaluation, and results of an innovative undergraduate engineering course at the U.S. Air Force Academy (USAFA). The course, ENGR 110 — Introduction to Engineering, is a problem‐based learning environment in which freshmen students work in teams to solve problems integral to a “mission to Mars”, that is, getting to Mars, constructing a research site on Mars, and developing a renewable power source there. In addition to traditional knowledge and skill objectives, the course focuses on “higher order” outcomes such as: framing and resolving ill‐defined problems; communicating via multiple media; exhibiting intellectual curiosity; and developing a rich conceptualisation of engineering. The course is described in terms of a set of pedagogical dimensions for problem‐based learning environments. Several cognitive assessment methods were used to assess student achievement and evaluate the effectiveness of the course. Results included statistically and educationally significant differences in “problem‐solving” between two classes of ENGR 110 students and two control classes of sophomore engineering students. 相似文献

We conducted a series of experiments to investigate the extent to which prompting the construction of a force diagram affects student solutions to simple mechanics problems. A total of 891 university introductory physics students were given typical force and motion problems under one of the two conditions: when a force diagram was or was not prompted as part of the solution. Results indicated that students who were prompted to draw the force diagram were less likely to obtain a correct solution than those who were not prompted to solve the problem in any particular way. Analysis of the solution methods revealed that those students prompted to use a diagram tended to use the formally taught problem‐solving method, and those students not prompted to draw a force diagram tended to use more intuitive methods. Students who were prompted to draw diagrams were also more likely to depict incorrect forces. These results may be explained by two factors. First, novice students may simply be more effective using intuitive, situational reasoning than using new formal methods. Second, prompting the construction of a force diagram may be misinterpreted by the student as a separate task, unrelated to solving the problem. For instruction, the results of this study imply that ignoring students’ prior abilities to solve problems and their necessary developmental stages in learning formal problem‐solving techniques may lead to serious mismatches in what is taught and what is intended to be learned. 相似文献

First-year computer science students are receiving early introduction to the software process through a problem solving and program development approach. We present a methodology that addresses the needs and difficulties of students learning programming, incorporating the tasks required for solving problems and writing programs. This approach allows for incremental exposure to the complex field of software engineering, consistent with the level of the introductory computing course, while providing the learner with fundamental skills applicable to other domains. The correlation between the software process and the problem solving/program development approach is also demonstrated. 相似文献

The present study was designed to investigate problem- and solution-related activity of elementary students in ill-defined and open-ended settings. One Grade 4/5 class of 28 students engaged in the activities of the “Engineering for Children: Structures” curriculum, designed as a vehicle for introducing science concepts, providing ill-defined problem solving contexts, and fostering positive attitudes towards science and technology. Data included video recordings, ethnographic field notes, student produced artefacts (projects and engineering logbooks), and interviews with teachers and observers. These data supported the notion of problems, solutions, and courses of actions as entities with flexible ontologies. In the course of their negotiations, students demonstrated an uncanny competence to frame and reframe problems and solutions and to decide courses of actions of different complexities in spite of the ambiguous nature of (arte)facts, plans, and language. A case study approach was chosen as the literary device to report these general findings. The discussion focuses on the inevitably ambiguous nature of (arte)facts, plans, and language and the associated notion of “interpretive flexibility.” Suggestions are provided for teachers on how to deal with interpretive flexibility without seeking recourse to the didactic approaches of direct teaching. But what happens when problems and solutions are negotiable, when there are no longer isolated problems which one tries to solve but problems which maintain complex linkages with ensembles of other problems and diverse constraints, or when problems and solutions are simultaneously invented?

Project high hopes summer institute: Curriculum for developing talent in students with special needs
This article examines a summer institute curriculum that was developed for and used with handicapped students who were identified as gifted in the area(s) of visual arts, performing arts, engineering, or life sciences. The students and the summer institute were part of a federally funded Javits program, Project High Hopes. The curriculum was real world, multi‐disciplinary and problem based in that it used a decaying water feature on the school grounds as its focus. Using a creative problem solving process, students identified problems with the water feature, developed solutions, created presentations, and presented their solutions to the school board. Student products are described as are conclusions, results and possible implications for other educational settings. 相似文献

If we carefully observe the spatial and temporal organization of students' pen strokes as they solve an engineering problem, can we predict their ability to achieve the correct answer? To address this question, 122 college students were asked to solve exam problems in an engineering course using a smartpen that recorded their writing as digitized timestamped pen strokes. The pen stroke data was used to compute a collection of 10 metrics characterizing various elements of problem-solving fluency including the tendency to progress down the page without revisions, the amount of time with no activity, and the frequency of constructing and using equations. The primary finding is that, on average across 13 different exam problems, these elements of problem-solving process explained 40% of the variance in scores of the correctness of the problem solution. In short, success on generating correct solutions was related to the fluency of the student's problem-solving process (i.e., working sequentially from the top to the bottom of the page, working without detours or long pauses, and working by constructing equations). This work is consistent with the idea that expertise in solving common engineering problems involves being able to treat them like routine rather than non-routine problems. 相似文献

While Physics Education Research has a rich tradition of problem-solving scholarship, most of the work has focused on more traditional, well-defined problems. Less work has been done with ill-structured problems, problems that are better aligned with the engineering and design-based scenarios promoted by the Next Generation Science Standards. This study explored the relationship between physics content knowledge and ill-structured problem solving for two groups of high school students with different levels of content knowledge. Both groups of students completed an ill-structured problem set, using a talk-aloud procedure to narrate their thought process as they worked. Analysis of the data focused on identifying students’ solution pathways, as well as the obstacles that prevented them from reaching “reasonable” solutions. Students with more content knowledge were more successful reaching reasonable solutions for each of the problems, experiencing fewer obstacles. These students also employed a greater variety of solution pathways than those with less content knowledge. Results suggest that a student’s solution pathway choice may depend on how she perceives the problem. 相似文献

ABSTRACTIntroductory undergraduate courses present an opportunity to use disciplinary concepts in solving authentic problems. Making complex natural systems accessible to students through computer-based models allows them to practice making evidence-based predictions and communicate understanding. Despite the importance of modelling tools in formal classrooms, gaps exist in our understanding of how post-secondary students engage in computer-based modelling. Introductory courses, particularly in the hydrosciences, typically do not use these tools. This mixed methods study examines students’ model-based reasoning about a water-related issue over two years in response to a flipped course model. Students in an introductory water course learned basic hydrologic content and used a computer-based water model to complete a project. Data came from a pre-/post-course assessment, student assignments, and student interviews. Results of quantitative and qualitative data analyses show that students in the revised version of the course (Year 2, n?=?53) increased their understanding of core hydrology concepts and performed better on their evaluation of a computer-based water model, than students in the initial course (Year 1, n?=?38). We tentatively attribute these observed changes to increased active learning opportunities surrounding computer-based modelling of water systems. Findings contribute to science literacy development, undergraduate science learning environment design, and undergraduate scientific modelling. 相似文献

Although many educators now recognize the value of problem‐based learning and experiential learning, undergraduate‐level food science courses that reflect these pedagogical approaches are still relatively novel, especially in East and Southeast Asia. Leveraging existing partnerships with farmers in Vietnam, a food science course for students at Nong Lam Univ. was designed and taught. The aim was to give students the opportunity to work in small groups and conduct evidence‐based research with farmers, apply food science principles, and develop Success Skills, including the ability to think critically and communicate clearly. Drawing on the experience of 2 student groups, this exploratory study describes what students learned from the process of conducting research. In one group, students learned to work through and resolve the challenge of initial disagreement and misunderstanding with farmers and ultimately carried out a project that aligned with the students’ research interests and farmers’ needs. Another group of students learned to consider the financial limitations of farmers when attempting to develop solutions for problems and ultimately worked with farmers to address a different problem that was less financially taxing. It is important to note the challenges of planning and teaching a course in which instructors are not able to predict exactly what students will learn or experience. This is largely dependent on each student's prior knowledge, experiences, and interests; yet this study demonstrates the transformative potential of teaching a research‐based food science course that gives students authentic opportunities to identify and address real‐world challenges. 相似文献

This study examined whether developing earlier forms of knowledge in specific learning environments prepares students better for future learning when they are placed in an unfamiliar learning environment. Forty‐one students in the fifth and sixth grades learned to program robot movements using abstract concepts of speed, distance and direction. Students in high‐transparency environments learned visual programming to control robots (eg, organizing visual icons), and students in low‐transparency environments learned syntactic programming to control robots (eg, text‐based coding). Both groups received feedback and models of solutions during the learning phase. The assessment midway showed students in both conditions learned equally well when solving problems using familiar materials. However, a difference emerged when students were asked to solve new problems, using unfamiliar materials. The low‐transparency group was more successful in adapting and repurposing their knowledge to solve novel problems that required the use of unfamiliar high‐transparency materials. Students in the high‐transparency group were less successful in adapting their knowledge when solving new problems using unfamiliar low‐transparency materials. Both groups then proceeded to learn in the opposing transparency environments. The posttest revealed the benefits of initial learning in low‐transparency environments as students performed better on repeated and new inferential problems across virtual and physical platforms. 相似文献
