Addressing Challenges in Narrative Writing: An Error Analysis of Eleventh Grade Senior High School Students' Use of Simple Past Tense

The motivation behind this review is to distinguish errors in the utilization of the basic past tense by 11th grade at Madrasah Aliyah Nurul Jihad in Indragiri Hilir. The exploration technique is descriptive qualitative, with an emphasis on information got from the writing tests. The information showed that students made errors in utilizing the straightforward past tense, which were delegated omission, addition, misformation, and misordering. There were 104 errors found, including 43 omissions, 16 additions, 20 misformations, and 25 misorderings. The most prevalent type of error was omission (42%), followed by misordering (24%), misformation (19%), and addition (15%). The prevalence of omission errors suggests that students struggle with understanding and applying the simple past tense in their narrative writing, often resulting in incomplete sentences or omitted words. To improve, students should engage in more practice with narrative text writing to enhance their grasp of the simple past tense.

Feasibility of Natural Indicators Worksheets for 11th grade Student

This study aims to determine the level of eligibility of worksheets for natural indicators of acid-base 11th grade Senior High School (SMA/MA) students in even semester. The population used in this study is a population sample consisting of six validators consisting of two content validator validators, two linguistic validator validators, and two graphic feasibility validators. Data collection instruments used were content eligibility questionnaire, linguistic feasibility questionnaire, and graphic eligibility questionnaire. The data analysis technique used is Gregory. Results Processing data in terms of content eligibility has a validity of 1 so that it has a very high level of content eligibility. For language eligibility, continued validity is obtained at 1 so that the level of language eligibility is also very high. However, the validity of the worthiness of the graphic is only 0.5 so that the level of feasibility of the graphic is still categorized as moderate. Thus, it can be concluded that LKPD of the natural indicators of acid-base for 11th grade students in even semester is feasible to be used in the learning process with very high criteria for content and linguistic aspects and moderate categories for graphic aspects.
