Investigated was the criterion validity of confidence-testing as applied to a multiple-choice test in introductory psychology. Examinees made confidence judgements in addition to choosing the correct alternative. The test was scored conventionally with a penalty for guessing and again using confidence-weightings. Over-all achievement for the academic year in psychology was the criterion for validity. There was greater reliability but no improvement in validity. High test anxiety was associated with low confidence and poor achievement.

Abstract - This research is aimed to find the effect of cooperative model learning think pair share type with experiment method toward learning physics result of the students at man west Lombok in academic year 2017/2018. The kind of this research is quasi experiment with Untreated control group design with pretest-posttest research design. The population of this research is all of the XI students of MAN West Lombok which consist of 34 students. Sampling jenuh technique is a way of taking the sample, while XI IPA 1 students as experiment class and XI IPA 2 as control class. The instruments that used are; multiple choice test and observation sheet. The amount of the multiple choice test are 25 questions where the test before has been through validity test, reliability, different capacity and standard of questions difficulty, while the observation sheet used to measure the affective and psychomotor score. Based on the result of the research that achieved from the mean score for pretest of experiment class is 40,19 and control class is 37,45, while the mean score of post-test experiment class is 73,52 and control class is 51,27. The hypothesis of the research is tested using t-test polled varians with significant standard 5% and achieved tresult 7,646 and ttable  2,021. Based on the criteria of hypothesis test, if tresult > ttable, it means Ho released and Ha accepted, where it can conclude that there is a effect of cooperative model learning think pair share type with experiment method toward learning physics result of the students at man west Lombok in academic year 2017/2018.

Penelitian  ini  bertujuan  untuk  mengetahui  ada  tidaknya  pengeruh  penerapan model pembelajaran Inkuiri terhadap hasil belajar kognitif dan sikap demokratis sisw a  MA  Darussalimin  NW  Sengkol  pada  mata  pelajaran  PKn tahun ajaran 2017/2018.   Penelitian  ini  menggunakan  pendekatan   kuantitatif   dengan  jenis penelitian  quasi  eksperimen  (eksperimen  semu)  yaitu  Nonequivalent  Control Group Design.  Sampel  dalam  penelitian  ini adalah sisw a kelas XI Agama sebanyak 21 orang sisw a sebagai kelas eksperimen dan sisw a kelas XI IPA sebanyak 21 orang sisw a  sebagai  kelas  control.  Instrument  pengumpulan  data menggunakan  tes pilihan ganda sebanyak 20 soal untuk hasil belajar kognitif dan instrument angket untuk  sikap  demokratis.  Berdasarkan  hasil uji hipotesis  uji-t untuk  hasil belajar diperoleh data thitung =1,85 dan t table = 1,684 dengan taraf signifikan 5% dan dk=42 jadi t hitung > t table. Sedangkan hasil analisis sikap demokratis dengan menggunakan skala likert yakni 81,36% dari sebelumnya 69,04% untuk kelas eksperimen  dan  73,65%  dari sebelumnya  65,08%  untuk kelas control.  Hal ini menunjukka   hipotesis  dalam   penelitian  diterima  atau dengan  kata  lain  ada pengaruh  penerapan  model pembelajaran  inkuiri terhadap hasil belajar kognitif dan sikap demokratis sisw a. AbstractThis  thesis  aimed  at  finding  out  the effectiveness  or uneffectiveness  of  using inquiry model in finding result of cognitive study and democratic attitude student of MA darussalimin nw sengkol in PPKn lesson in academic year 2017/2018. The sample in this research w as IX (nineth) of Islamic class. That w as 21 student as experimental class and student of IX (nineth) IPA that w as 21 studenas control class. The instrument w as collecting the data used multiple choice test, there w ere 20  questions  for  the  resulted  of  cognitive  study  and  instrument  quisioner in democratic attitude. Based on the result of hipotesis experimental for the result of study the researcher got tcount = 1,85 and t table = 1,684 in taraf significant 5% and DK = 40. So tcount >t table.While analisist result of democratic attitude w as used likert scala that w as 81,36% w hich before 69,04% for experimental class and73,65% for control class. So based on the date the researcher got the other w ord it w as effective in using inquiry model to cognitive result of study and democratic attitude.Keywords: Inquiry, result of PPKn lesson and Democratic Atitude

Evolution as a subject in lecture is a material that has many concepts, theoretical, and hard to understand. Then it impacts some misconception on students. Misconception is a situation where the concept that students’ get is different from what experts' mean. The purpose of this research is to know the evaluations' concepts that be misconception by biology' students of Padang state University who has been learning evolution subject and to know the percentage of misconception which had been happened. This research is a desriptive study. Subject of this research is the students of biology of Padang state University who has been learning evolution in second semester in academic year 2016/2017. Sample of this research is all subject that still active in college. Variable of this research is students' misconception toward concpets in evolution material. Instrument of this research is multiple choice test that be equipped with criteria of certainty of response index (CRI) have the form of numeral 1, 2 and 3 which be choosed based on level of conviction of the answer. Analysis of the data used quantitative with count percentage of students have misconception that is students who are choosen flase answer ans index 3 in CRI. Based on data analysis indicate students of biology of Padang University did misconception in evolution material after learning evolution subject with high percentage be found in basic material about definition and the scope of evolution is 39.52% and the low percentage of misconception be found in basic material about Darwin's evolution is 15.86%.

Two experiments investigated the information conveyed by intonation from speaker to listener. A multiple-choice test was devised to test the ability of 48 adults to recognize and label intonation when it was separated from all other meaning. Nine intonation contours whose labels were most agreed upon by adults were each matched with two English sentences (one with appropriate and one with inappropriate intonation and semantic content) to make a matching-test for children. The matching-test was tape-recorded and given to children in the first, third, and fifth grades (32 subjects in each grade). The first-grade children matched the intonations with significantly greater agreement than chance; but they agreed upon significantly fewer sentences than either the third or fifth graders. Some intonation contours were matched with significantly greater frequency than others. The performance of the girls was better than that of the boys on an impatient question and a simple command which indicates that there was a significant interaction between sex and intonation.
