Rapid advancements in hardware, software, and connectivity are helping to shorten the times needed to develop computer simulations for science education. These advancements, however, have not been accompanied by corresponding theories of how best to design and use these technologies for teaching, learning, and testing. Such design frameworks ideally would be guided less by the strengths/limitations of the presentation media and more by cognitive analyses detailing the goals of the tasks, the needs and abilities of students, and the resulting decision outcomes needed by different audiences. This article describes a problem-solving environment and associated theoretical framework for investigating how students select and use strategies as they solve complex science problems. A framework is first described for designing on-line problem spaces that highlights issues of content, scale, cognitive complexity, and constraints. While this framework was originally designed for medical education, it has proven robust and has been successfully applied to learning environments from elementary school through medical school. Next, a similar framework is detailed for collecting student performance and progress data that can provide evidence of students' strategic thinking and that could potentially be used to accelerate student progress. Finally, experimental validation data are presented that link strategy selection and use with other metrics of scientific reasoning and student achievement.

Improve Student Learning

Teaching is filled with spirited debate about the best practices for improving students' learning and performance. Today, educators from different parts of the world are supporting the use of rubrics as an instructional tool and highlighting the enormous contributions that rubrics can make in the teaching-learning paradigm. A rubric is a useful grading tool which can help instructors to grade students' work in a more consistent, reliable and unbiased manner. A well-designed rubric can help students to identify their strengths and weaknesses and be more objective about their own quality of work. Although some studies have examined the benefits of rubrics on student performance levels; nevertheless, research on rubrics is still at an early stage. In this paper we will explore what a rubric is, the different types of rubrics that can be utilized in the classroom and the process of constructing a rubric. We will also discuss how the application of rubrics in teaching can help educators to improve student learning and provide more effective feedback on student performance.

This paper investigates the planning and problem-solving abilities of normal adult subjects using a complex version of Shallice's (1982, 1988) Tower of London (TOL) task. Subjects were required to plan a fluent solution to a range of 5-disc TOL puzzles and then execute their formulated plans as fast as possible. The number of errors and the times taken to prepare the most efficient solutions increased monotonically with the number of chunks of subgoal moves. A subgoal move is a move that is essential for the solution of the puzzle, but which does not place a disc into its goal position. A subgoal chunk is a consecutive series of subgoal moves that all transfer discs to and from the same pegs. Furthermore, preparation time was found to be sensitive to a manipulation that increased the number of competing alternative choices, at critical steps in move selection. When subjects planned their action sequences “on-line”, analyses of individual moves and individual move latencies suggested that planning TOL solutions was limited by the difficulty in evaluating and selecting one action (or one subgoal chunk) from the set of competing potential actions at each step in the course of problem solving.

The teaching and learning environment have subsequently expanded. For the Independent Landscape Design course offered at UiTM Perak Branch, the online distance learning (ODL) has demonstrated the changes of delivery approach in teaching landscape design process. This design-based syllabus is more acquainted with face to face or physical teaching learning environment. Aligned with the Educational 5.0 @ Universiti Teknologi MARA that embraces values and future progressive thinking, this course has adopted MOOCLAA350 to engage and equip these design students with significant understanding, graphic presentation skills as well as technical aspects related to design developments and constructions. This paper analyses student performance throughout the ODL implementation, adopting MOOC and other relevant online platforms during this Covid-19 pandemic outbreak. An online survey supported with a comparative analysis between semesters was conducted to evaluate the students’ readiness, challenges and performance throughout the semester. Some tools and techniques to ensure the continuity of learning during the current pandemic are described. The findings revealed factors contributing to student performance and the reality behind the success of this new teaching strategy which is practical for landscape architecture programs and may also be relevant to other design-based programs or courses.

Abstract Introduction: Teaching learning in the times of Covid 19 pandemic needs to be revamped in order to follow norms of social distancing. Therefore, online classes are a necessity now.Methodology: We registered our institution on Microsoft Teams under educational institutes. Entire college faculty was registered along with undergraduates and post graduate students. E- classes were planned after a professional demonstration.Results: The feedback of e classes given by students was encouraging. They were satisfied by the teacher’s way of delivering lecture. The students felt, on line classes are almost similar to offline classes. The main hinderance in e-classes was internet connection.Conclusion: The e classes helped to continue the teaching learning activities during restrictions because of Covid19 pandemic

Abstract A new setup named Fast On-line Reaction Apparatus (FORA) is presented which allows for the efficient investigation and optimization of metal carbonyl complex (MCC) formation reactions under various reaction conditions. The setup contains a 252Cf-source producing short-lived Mo, Tc, Ru and Rh isotopes at a rate of a few atoms per second by its 3% spontaneous fission decay branch. Those atoms are transformed within FORA in-situ into volatile metal carbonyl complexes (MCCs) by using CO-containing carrier gases. Here, the design, operation and performance of FORA is discussed, revealing it as a suitable setup for performing single-atom chemistry studies. The influence of various gas-additives, such as CO2, CH4, H2, Ar, O2, H2O and ambient air, on the formation and transport of MCCs was investigated. O2, H2O and air were found to harm the formation and transport of MCCs in FORA, with H2O being the most severe. An exception is Tc, for which about 130 ppmv of H2O caused an increased production and transport of volatile compounds. The other gas-additives were not influencing the formation and transport efficiency of MCCs. Using an older setup called Miss Piggy based on a similar working principle as FORA, it was additionally investigated if gas-additives are mostly affecting the formation or only the transport stability of MCCs. It was found that mostly formation is impacted, as MCCs appear to be much less sensitive to reacting with gas-additives in comparison to the bare Mo, Tc, Ru and Rh atoms.
