Abstract: A kinetic façade responds to user requirements and environmental conditions. In designing a kinetic façade, kinetic patterns play a key role in determining its performance. This paper proposes a biomimetic method for the multi-objective optimization for kinetic façade design. The autonomous decentralized control system is combined with flocking algorithm. The flocking agents are autonomously reacting to sensor values and bring about kinetic patterns changing over time. A series of experiments were conducted to verify the potential and limitations of the flocking based decentralized control. As a result, it could show the highest performance balancing multiple objectives such as solar radiation and openness among the comparison group.
Abstract: Business education has been criticized for being too theoretical and distant from business life. Different types of experiential learning environments ranging from manual role-play to computer simulations and enterprise resource planning (ERP) systems have been used to introduce the realistic and practical experience into business learning. Each of these learning environments approaches business learning from a different perspective. The implementations tend to be individual exercises supplementing the traditional courses. We suggest combining them into a business skills laboratory resembling an actual workplace. In this paper, we present a concrete implementation of an ERP-supported business learning environment that is used throughout the first year undergraduate business curriculum. We validate the implementation by evaluating the learning outcomes through the different domains of Bloom’s taxonomy. We use the role-play oriented practice enterprise model as a comparison group. Our findings indicate that using the ERP simulation improves the poor and average students’ lower-level cognitive learning. On the affective domain, the ERP-simulation appears to enhance motivation to learn as well as perceived acquisition of practical hands-on skills.
Abstract: The aim of this study was to examine the effect of
cooperative learning method on student’s academic achievement and
on the achievement level over a usual method in teaching different
topics of mathematics. The study also examines the perceptions of
students towards cooperative learning. Cooperative learning is the
instructional strategy in which pairs or small groups of students with
different levels of ability work together to accomplish a shared goal.
The aim of this cooperation is for students to maximize their own
and each other learning, with members striving for joint benefit.
The teacher’s role changes from wise on the wise to guide on
the side. Cooperative learning due to its influential aspects is the
most prevalent teaching-learning technique in the modern world.
Therefore the study was conducted in order to examine the effect
of cooperative learning on the academic achievement of grade 9
students in Mathematics in case of Mettu secondary school. Two
sample sections are randomly selected by which one section served
randomly as an experimental and the other as a comparison group.
Data gathering instruments are achievement tests and questionnaires.
A treatment of STAD method of cooperative learning was provided
to the experimental group while the usual method is used in the
comparison group. The experiment lasted for one semester. To
determine the effect of cooperative learning on the student’s academic
achievement, the significance of difference between the scores of
groups at 0.05 levels was tested by applying t test. The effect size
was calculated to see the strength of the treatment. The student’s
perceptions about the method were tested by percentiles of the
questionnaires. During data analysis, each group was divided into
high and low achievers on basis of their previous Mathematics result.
Data analysis revealed that both the experimental and comparison
groups were almost equal in Mathematics at the beginning of the
experiment. The experimental group out scored significantly than
comparison group on posttest. Additionally, the comparison of mean
posttest scores of high achievers indicates significant difference
between the two groups. The same is true for low achiever students
of both groups on posttest. Hence, the result of the study indicates
the effectiveness of the method for Mathematics topics as compared
to usual method of teaching.
