The purpose of this research is to reveal and describe how the self-efficacy of mathematics teachers in Cianjur towards the dynamics of learning during the Covid-19 pandemic. The research was conducted in Cianjur Regency. The methodology used is descriptive quantitative method. The technique of collecting data is through questionnaires given by purposive and snowball sampling techniques. Data analysis uses descriptive statistics which do not aim to make conclusions about the entire population but rather help understand the details of the sample. The results showed that the overall self-efficacy of Mathematics Teachers in Cianjur was in the moderate category. Likewise, four of the seven constructs on teacher self-efficacy are Mathematics Knowledge Self-efficacy (KS), Instructional Self-efficacy (IS), Outcome Expectancy (OE) and Technology Literacy (TL) in the medium category. This means that teachers believe they have the ability to carry out their duties in the midst of a pandemic even though they still need development related to the four constructs. However, the other constructs namely Motivational Self-efficacy (MS), Engagement Self-efficacy (ES), and Disciplinary (as in classroom management) Self-efficacy (DS) are in the high category. This condition shows that teachers are able to provide motivation, students can be actively involved in learning and learning continues to be carried out conducive even though learning is carried out in the midst of a pandemic condition.
本研究的目的是揭示和描述新冠肺炎大流行期间Cianjur数学教师的自我效能感对学习动态的影响。这项研究是在cianjurr摄政进行的。研究方法采用描述性定量方法。收集数据的技术是通过有目的的问卷调查和滚雪球抽样技术。数据分析使用描述性统计,其目的不是得出关于整个人口的结论,而是帮助了解样本的细节。结果表明,钱玉尔市数学教师的整体自我效能感处于中等水平。同样,在教师自我效能感的七个构念中,有四个构念是中等类别的数学知识自我效能感(KS)、教学自我效能感(IS)、结果期望(OE)和技术素养(TL)。这意味着教师相信他们有能力在大流行中履行自己的职责,尽管他们仍然需要与这四个结构相关的发展。然而,其他构念即动机自我效能感(MS)、敬业自我效能感(ES)和纪律自我效能感(如课堂管理)属于高范畴。这种情况表明,教师能够提供动力,学生可以积极参与学习,即使在大流行的情况下进行学习,学习也能继续进行有益的学习。

Students who tend to only follow directions from the teacher cause learning to be meaningless. This meaningless learning causes students to be unable to master mathematical concepts and principles, so that when given a problem students are unable to work on the problem independently. Therefore, this study aims to describe the mathematical understanding ability of MTs students on algebraic material using descriptive qualitative. The research subjects used were 6 students who were taken using purposive sampling technique. The test instrument is in the form of a description of algebraic material consisting of 7 questions that are adjusted to the indicators of mathematical understanding ability according to the Ministry of National Education and non-test in the form of interviews. The data analysis technique used in this research is data collection, data reduction, data presentation, and drawing conclusions. The results of the student's instrument will be analyzed based on indicators of mathematical understanding ability by converting the score into percentage form. The results obtained from 7 indicators of mathematical understanding, 5 of which are already above 50% and 2 others are still below 50%. These results indicate that students' mathematical understanding abilities are still not optimal because students still have difficulty applying their understanding in solving algebraic questions, especially on indicators of building necessary conditions and applying concepts or algorithms in problem solving.
只听从老师指示的学生会使学习变得毫无意义。这种无意义的学习导致学生无法掌握数学概念和原理,因此当给学生一个问题时,学生无法独立解决问题。因此,本研究旨在运用描述性定性的方法来描述mit学生对代数材料的数学理解能力。研究对象为6名学生,采用有目的抽样法。测试工具采用代数材料描述的形式,由7道题组成,根据教育部数学理解能力指标进行调整,非测试形式为访谈。本研究使用的数据分析技术是数据收集、数据简化、数据呈现和得出结论。学生的乐器成绩将根据数学理解能力的指标进行分析,将分数转换为百分比形式。7项数学理解指标的结果,其中5项已超过50%,2项仍低于50%。这些结果表明,学生的数学理解能力仍然不是最优的,因为学生在解决代数问题时仍然难以应用他们的理解,特别是在建立必要条件和应用概念或算法解决问题的指标上。
