The instrument of collecting the data was used multiple-choices and questionnaires. In this research, the writer rendered treatment and prepared a test in the form of multiple-choices to look the effect of Inquiry-Based Learning and questionnaires for look the critical thinking. The result of data analysis indicated at third-semester students of Faculty of Education, and Education of Science Qamarul Huda University, Bagu, Central Lombok attained high score on post-test whom were treated by Inquiry-Based Learning. It means that Inquiry-Based Learning gave a significant effect on critical thinking of students in reading. It was proven by the lowest and highest in pre-test score was 30 and 50 and post-test was 35 and 65. Then, the result of hypothesis testing was the alternative hypothesis accepted. It was provable that t-test was higher than t-table, which was the score of t-test was 3.81 and t-table in df 17 with significant 0.05 was 1.753. Inquiry-Based


INTRODUCTION
There are four academic skills in English language that should be mastered by the students such as listening, reading, writing, and speaking. In mastering English well. Especially reading is one of the important skills in teaching English. where reading is a process that is applied and conducted by a reader to acquire a message that has been told by a writer in writing script. Reading enable people to find out information from a variety of text, newspapers, magazine, advertisement, brochures, etc. As part of language skill, reading plays an important role in the success of language learning. In the reading activity, we are not only reading the text but also trying to understand what we are reading.
The general objective of reading is that the students can understand and interpret the content of reading texts through observation and interpretation. Related to English reading in general, there are some advantages students may obtain. Students may be able to find a lot of new information to expand their knowledge and to enrich their vocabulary. The students are good in reading, they can rapidly get the main idea of the text, know the explicit and implicit information about the text, finding detailed information, finding the word references, making an inference, etc.
In the educational field, in doing the observation at third-semester students of Faculty of Education, and Education of Science Qamarul Huda University, Bagu, Central Lombok the researcher found that the students are lack of constructing the meaning in reading, especially to finding main ideas, specific, and implicit information from the text. it because the students are lack of thinking critically. Where having the ability to think critically is an important skill that should have by students because critical thinking plays an important role for the students. Critical thinking is the best ability to understand a concept fully, and the best way to solve the problem since it requires looking at the issue from several standpoints before reaching a final decision. Critical thinking is very important in reading.
Based on the problem that the researcher found at third-semester students of Faculty of Education, and Education of Science Qamarul Huda University, Bagu, Central Lombok the researcher wants to give the appropriate strategy in teaching reading to solve the problem and the strategy that the researcher wants to give is Inquiry-Based Learning.
Inquiry-Based learning is one kind of strategy that demanded students to think where the students were involved to formulate questions, observation, and also finding the information. According to Paula (2006: 20) inquiry-based learning is a strategy to learning that involves a process of exploring the natural or material world, and that leads to asking questions, doing observation, and discussing the result of the observation to get the conclusion. It provides students the opportunity to construct the understanding necessary to produce deeper learning. Inquiry-Based Learning strategy also serves as a stimulus for learning, thinking, and questioning. From those explanations, the researcher decides to investigate the effect of Inquiry-Based Learning strategy in teaching reading at third-semester students of Faculty of Education, and Education of Science Qamarul Huda University, Bagu, Central Lombok in academic year 2019/2020.
Reading is the understanding of the written word, the understanding of the content that is being read, and the construction of meanings of the text. Reading is a purposeful and active process. A reader reads to understand, to remember what is understood and put the understanding to use. A reader can read a text to learn, to find out information, or to be entertained (Healy, 2002:3).
According to Leung (1998: 12) inquiry can be viewed as a process for answering questions and solving problems based on facts and observations. At the classroom level, inquiry is a teaching strategy. The definition states that Inquiry-Based Learning gives the teacher the opportunity to help students learn the content and course concept by having them chance to explore a question, develop the information, and research a hypothesis. Thus, giving students more opportunity to inflict on their own learning, gain a deeper understanding of the course concepts in an integrated fashion, and become better critical thinkers. In addition, the inquiry approach is more focused on using and learning as a means to develop information-processing and problem-solving skills. The system is more students centered, with the teacher as a facilitator of learning. Critical thinking is the correct assessing of statements (Ennis, 1962: 179). Critical thinking includes the ability to respond to material by distinguishing between facts and opinions or personal feelings, judgments and inferences, inductive and deductive arguments, and the objective and subjective. In addition Ennis (1992) in Mark Mison (2008, maintained that the skills associated with critical thinking can be learned independently of specific disciplines, and can be transferred from one domain to another. For him, the process of critical thinking is deductive: it involves applying the principles and skills of critical thought to a particular discipline.

RESEARCH METHOD
The experimental method was used in this research. Thus, experimental research is the proof of a hypothesis which seeks to make up two factors into a casual relationship through the study of contrasting situations which have been controlled on all factors the one of interest, the latter being either the hypothetical cause or the hypothetical effect (Singh, 2006:135). The research was a categorized pre-experimental design because in this study the researcher only used an experimental class without control class. In this case, the researcher was used One Group Pretest-Posttest.

Population and Sample
The population in this study was at third-semester students of Faculty of Education, and Education of Science Qamarul Huda University, Bagu, Central Lombok in academic year 2019/2020.There was only one class of the third-semester students consisted of 18 students. The researcher used a surfeited sampling method for choosing the sample. So, the researcher had determined the sample using surfeited sampling. Surfeited Sampling is the technique to determine sample if the whole population use as sample and the population is less than 30 students (Sugiyono 2014: 85). Based on the construct above, the researcher has used the whole of the population as sample; the populations are 18 students and it also for sample.

Instruments
The instrument was used in this research was multiple choice that consist 50 items to measure the students' reading along with critical thinking and questionnaires to know their students' respons on Inquiry technique based-learning by choosing the option on questionnaires which was Likert scale which consisted of 7 items. Each item has 4 options with the first option scores 4 (Very Agree) , the second option scores 3 (Agree), the third option scores 2 (Disagree), and the last option scores 1 (Very not agree). And for multiple choice that consist 50 items. Each correct answer was scored 5 and if incorrect was 0. So, the highest possible score for students was 20. The technique data analysis employed a descriptive analysis to know the score of the mean, median, and mode. The inferential statistic was to measure the data significant or not. Then, the result of the t-test will compare to t-table to know significant or not.

Data Analysis
In this study, the researcher wants to show the statistical analysis of the data obtained, this analysis leads the discussion toward the finding at the investigation. There are several steps to measuring whether between them are having significance effect such as descriptive statistic and T-test for reading test and questionnaire for measure students' critical thinking.
