The Ideal

Beyond students’ ability to manipulate variables and solve problems, chemistry instructors are also interested in students developing a deeper conceptual understanding of chemistry, that is, engaging in the process of sensemaking. The concept of sensemaking transcends problem-solving and focuses on students recognizing a gap in knowledge and working to construct an explanation that resolves this gap, leading them to “make sense” of a concept. Here, we focus on adapting and applying sensemaking as a framework to analyze three groups of students working through a collaborative gas law activity. The activity was designed around the learning cycle to aid students in constructing the ideal gas law using an interactive simulation. For this analysis, we characterized student discourse using the structural components of the sensemaking epistemic game using a deductive coding scheme. Next, we further analyzed students’ epistemic form by assessing features of the activity and student discourse related to sensemaking: whether the question was framed in a real-world context, the extent of student engagement in robust explanation building, and analysis of written scientific explanations. Our work provides further insight regarding the application and use of the sensemaking framework for analyzing students’ problem solving by providing a framework for inferring the depth with which students engage in the process of sensemaking.

This study proposed a calligraphy brush trajectory model for the behavior of brush movements and provided the three-dimensional handle coordinates for a robotic arm to write calligraphy. This study dealt with basic footprints and bent lines of calligraphy and proceeded as follows. The shape of brush footprints on paper was measured, which provided the positions of the brush relative to its handle. These brush footprints were scanned and corrected for skew using the Direct Linear Transformation. The outer frame of each basic footprint was characterized using Bézier curves. Bent lines were drawn to derive the brush trajectory model, and it was used to derive the relationship between the trajectories of the brush and handle. By characterizing the changes in the footprints with handle displacement, we obtained the relationship between the handle coordinates and the position and shape of the brush footprints. The written characters were evaluated based on their size, position, and stroke balance, with a maximum score of 100 in each category. The average score of the “Yong” character written using our brush trajectory model was approximately 94 points; when the handle coordinates were fixed to the center of each footprint, the average score was only 88 points.

To acquire a fast method for better volume estimation, a novel soft sensor technique is proposed in this paper. Based on the principle of energy conservation as well as the ideal gas law, mathematical models of charging and discharging process are set up. Afterwards, simulations are carried out to explore the relationship between the estimated volume and the pressure stable time. Finally, experiments with different pneumatic cylinders are conducted to select the suitable estimation mode and also optimize the parameters. Results show that in discharging mode, the average estimation error for volume estimation can be less than 4% with both low pressure and high pressure, making this method quite suitable for industrial application.

The misconception is a problem in learning and it is very necessary to solve it so that learning is better. Students who are identified with misconceptions on material concepts can make it difficult for them to believe new concepts that are true. The purpose of this study is to identify the existence of misconceptions in students in an ecosystem material concept that they have studied previously. This study uses a descriptive method with a quatitative approach. The research was conducted at Senior High School (SMA) in Sukabumi Regency. The subjects studied were 36 students of class XI MIPA 5. The instrument used was 45 multiple choice questions with the help of the Certainty of Response Index (CRI). The results showed the understanding of students in the percentage of conceptual understanding (PK), understanding the concept of being unsure (PKKY), Misconception (M), and not knowing the concept (TTK) were 20%, 6%, 32%, 42%. The highest misconception percentage at level 1 after testing was at the indicator describing the relationship between ecosystem components (60%), level 2 understanding the pattern of interactions between organisms (53%), and the lowest on indicators showing succession definition (12%). Therefore, misconceptions among students in ecosystem material need to be eliminated by choosing the right method, learning model, and approach. Abstrak.

The Relationship

In collaborative learning, the intuition “the more device, the merrier” is somehow widely acknowledged, but little research has investigated the relationship between device-student ratio and the learning outcome. This study aims to investigate not only the main effect of different device-student ratio, also to identify the moderators in the learning context including task complexity, external script availability and students’ familiarity to the collaboration settings. A three-round quasi-experiment was conducted in a primary school in mainland China, 130 fifth-grade students from four classes participated. Group worksheet including conceptual understanding and problem-solving tasks were used to collect participants’ inquiry performance. Repeated measures ANOVA was employed in data analysis. Findings indicate that 1:m device-student ratio could be beneficial, and external scripts, and prior collaboration experience could moderate such effect. The different effect of 1:m device-student ratio to 1:1 is only significant in the situation when students are faced with relatively simple task, and the effect size is larger when external script is present. When the task is more complicated, such effect of device-student ratio would only emerge after a period of collaboration. This finding challenged the intuition that one-to-one device-student ratio could be better. Related discussions and recommendations to teaching were made.
